Objective: We aimed to analyse patient outcomes following open (OAR) or endovascular repair (EVAR) of an abdominal aortic aneurysm (AAA) in Finland and Sweden from 1998 to 2017. Both intact and ruptured AAAs (rAAAs) were included in the analysis. Methods: Patient-level data from national registries in Finland and Sweden were analysed, pairing operations for intact and ruptured AAA repair with mortality data (date of death). All-cause mortality was the primary endpoint. Anonymized patient data from both countries were pooled, comprising a total of 32,324 operations. Ruptured and intact AAAs were considered separately. In total, EVAR was performed on 9619 intact AAAs and 1470 rAAAs, while OAR was performed on 13,241 intact AAAs and 7994 rAAAs. The patient\'s age, sex and the date of operation were obtained as demographic information. Cox regression and Kaplan-Meier analyses were used to evaluate long-term (10-year) survival after the treatment of AAA or rAAA with either modality. Kaplan-Meier analysis was performed in three different age groups (<65 years, 65-79 years and ≥80 years). Results: Considering all age groups together, the 1-, 3- and 10-year Kaplan-Meier survival rates after EVAR were 93.4%, 80.5% and 35.3%, respectively, for intact AAA repair and 67.2%, 55.9% and 22.2%, respectively, for rAAA repair. For OAR of intact AAAs, the 1-, 3- and 10-year Kaplan-Meier survival rates were 92.1%, 84.8% and 48.7%, respectively. The respective rates for OAR of rAAAs were 55.4%, 49.3% and 24.6%. In a Cox regression analysis, a more recent year of operation was associated with improved survival, and older age affected survival negatively for both intact and ruptured AAA repair. If patients survived the first 90 days after the operation, the survival after intact AAA repair was 13.5 years for those <65 years (general population: 18.0 years), and 7.3 years for those ≥80 years (general population: 7.9 years). After rAAA repair, the mean survival was 13.1 years for patients <65 years and 5.5 years for patients ≥80 years, respectively. Conclusions: The long-term survival of patients undergoing intact AAA treatment at the age of 80 or older is close to that of the general population, provided they survive the operation. Conversely, for patients younger than 65, the long-term survival is markedly worse. The long-term survival of AAA patients has improved over time. Open surgery is still a safe and effective option for young patients undergoing intact AAA repair. Our results support the ESVS guidelines recommendation of EVAR being the first-line treatment for patients with rAAA.

OBJECTIVE: The objective of this case series is to investigate the outcomes of double-fenestrated physician-modified endografts (PMEGs) in patients with distal anastomotic aneurysms following open repair of the ascending aorta or proximal arch replacement.
METHODS: All consecutive patients with a distal anastomotic aneurysm following open ascending aorta surgery who underwent aortic arch repair with a homemade double-fenestrated stent-graft from 2017 to 2023 were reviewed. Study endpoints included technical success, 30-day, and long-term follow-up analysis of mortality, morbidity, and re-interventions.
RESULTS: 10 patients were treated with double-fenestrated PMEGs for anastomotic aneurysms following open surgery of the ascending aorta. Of these, nine were male with a mean age of 58 years. Nine patients were initially treated for acute dissection, and two had mechanical aortic valves. The mean time between open surgery and the treatment of the pseudoaneurysm was 4.15 years. Technical success was 100%. The proximal landing zone was consistently in zone 0, and all endografts were deployed via femoral access. Early outcomes revealed one endoleak (type 1a), which was successfully treated by prompt reintervention. No deaths or strokes occurred during the early postoperative period. During long-term follow-up (mean time 35 months), no endoleaks requiring intervention occurred, and there were no reports of stent fractures or migrations. No patient died from an aortic-related cause.
CONCLUSIONS: Aortic arch repair with double-fenestrated PMEGs for distal anastomotic aneurysms after open surgery is feasible and represents a promising alternative in patients ineligible for redo surgery.

UNASSIGNED: This single-center study aimed to assess patients who underwent intentional percutaneous endovascular aortic aneurysm repair (pEVAR) with Hybrid Technique combining a single Perclose (Abbott, Abbott Park, Illinois) Suture-Mediated Closure Device + single Angio-Seal VIP 8F (Terumo, Tokyo, Japan) and compare outcomes with the standard Dual Perclose technique. Materials and Methods: Consecutive elective pEVAR patients treated from November 2022 to November 2023, with healthy femoral accesses and introducer sheaths ≤20 French (F) outer diameter, were included. Coin-toss randomization determined whether a combination of single Perclose Device + single Angio-Seal VIP 8F (Hybrid Technique) or the standard double Perclose Devices (Dual Perclose) was used. In Hybrid Technique, a single Perclose device was positioned at 12 o\'clock; a single Angio-Seal VIP 8F was placed after sheaths removal. Dual Perclose followed standard procedure. Primary endpoints included immediate hemostasis, sheath diameter differences, access conversion rate, technical success, and cost analysis.
UNASSIGNED: The study involved 60 pEVAR patients (median age=78, interquartile range [IQR]=72-85 years) within the inclusion criteria. In 14 (24%) cases, only 1 femoral access was studied. There were 106 pEVAR accesses, with 58 (54.7%) in the Hybrid Technique group and 48 (45.3%) in the Dual Perclose group. Both groups exhibited homogeneity in pre-operative characteristics and sheath diameter (Hybrid Technique-16F vs Dual Perclose-18F; p=0.202). Immediate hemostasis was achieved in 100% of the Hybrid Technique group vs 87.5% for the Dual Perclose group (p=0.006). Surgical access conversion was unnecessary. Technical success was 100%, with all 6 femoral bleeding cases after Dual Perclose resolved endovascularly, using additional devices. Cost analysis showed a median cost of 330 euros (IQR=0) for the Hybrid Technique group vs 384 euros (IQR=360-456) for the Dual Perclose group (p<0.001). Thirty-day mortality was 3%, in 2 fragile patients, without access-related complications. Multivariate analysis identified Dual Perclose access (odds ratio [OR]=35.6; 95% confidence interval [CI]=18.3-36.8; p<0.001) and obesity (OR=19.7; 95% CI=1.4-23.9.5; p<0.001) as independent risk factors for immediate hemostasis failure. Median follow-up was 134 days (IQR=41-227), with 1 Hybrid Technique case (2%) successfully treated with thrombin injection for a small femoral pseudoaneurysm after 62 days.
UNASSIGNED: The elective Hybrid Technique with combination of single Perclose Device + single Angio-Seal VIP 8F during pEVAR in selected patients appears to be non-inferior to the standard Dual Perclose procedure. It demonstrates a positive trend in reducing immediate hemostasis failure and costs. Both procedures achieved technical success and avoiding surgical access conversions.
CONCLUSIONS: This study introduces a novel elective hybrid technique combining a single Perclose device with a single Angio-Seal VIP 8Fr for percutaneous endovascular abdominal aortic interventions. Results for hybrid technique showed 100% technical success and efficient immediate hemostasis, while costing less than standard dual Perclose procedure. Both procedures did not require surgical conversions. Despite being a single-center study, it demonstrates potential benefits of the intentional application of this hybrid technique towards minimally invasiveness. Obesity and dual Perclose technique were identified as independent risk factors for hemostasis failure, reaffirming the hybrid technique procedure\'s efficacy as well as and non-inferiority to standard procedure.

UNASSIGNED: To report results of application a new stent graft design for the treatment of patients with thoraco-abdominal aneurysms (TAAAs), which was co-invented by a vascular surgeon. This is a retrospective observational study.
UNASSIGNED: The Colt is a self-expanding stent graft, composed of nitinol metal stents creating a special exoskeleton with asymmetric springs covered with polyester material. The Colt device offers some advantages over existing stent graft options. The main body is available in two different diameters on both ends and in three different lengths. It has four branches pointing downward and coming from the main stent graft at two levels. It offers the physician an opportunity to decide which branch to choose for the target vessel. It may be implanted alone or extended proximally and distally. Balloon expandable and/or self-expanding stent grafts are used to create the visceral branches. In complex extensive aneurysms, the procedure is divided into two or three stages to minimize the risks of spinal cord ischemia.
UNASSIGNED: Between August 2015 and December 2021, twenty-two Colt stent grafts were implanted in twenty males and two females (aged 56-81) with TAAAs (eight Type II; twelve Type III; two Type IV). The mean aneurysm diameter was 73.4 mm (range 64-83). All patients were asymptomatic. Eighty-five target vessels were reconstructed using either self-expanding or balloon-expandable stent grafts. Fourteen bifurcated, six custom-made tubes and two aortouniiliac (AUI) stent grafts were used as distal extensions to the Colt device. Completion angiography revealed no type I endoleaks. Five patients had Type II endoleaks which were treated conservatively. There were no intraoperative deaths. One patient died on the 7th postoperative day from multiorgan failure. We did not observe any other complications within 30 days after implantation. One patient died from Covid-19 two months after discharge. Follow-up ranged from three to 75 months. There was no migration or dislocation of the docking station or proximal and distal extensions. All Colt device prostheses remained patent, however, two branches leading to the coeliac trunk were found occluded at the time of the 12-month CTA, without any symptoms. In two patients, there were late problems with three renal bridging stent grafts. One of the Type II endoleaks resolved spontaneously after one year, while four others remain under observation. No patient had an increase in sac diameter.
UNASSIGNED: Results from the current series are promising. The Colt stent graft can be applied to a large variety of TAAA anatomies, which may facilitate the development of new \"off-the-shelf\" devices in the future.

OBJECTIVE: This study aims to assess the efficacy and complications associated with upper limb catheterization during complex aneurysm endovascular surgery repair.
METHODS: A systematic review was conducted following PRISMA guidelines, involving a search across PubMed, Cochrane CENTRAL, and Web of Science. Primary endpoint was represented by 30-day stroke. Secondary endpoints were target vessels technical success, 30-day mortality, local access-related complications. Meta-analyses were performed using a random-effects model.
RESULTS: Sixteen observational studies encompassing 4,137 patients were included. The 30-day stroke incidence for upper limb access was 1.4% (95% CI 1.0%-1.8%), slightly higher than lower limb, despite not statistically significant. Mortality varied between 0-6.8%, and local access-related complications occurred in 3.2% (95% CI 1.9%-4.4%). Technical success in target vessel catheterization was 99.2% (95% CI 98.4%-100.0%).
CONCLUSIONS: This systematic review and meta-analysis demonstrate the safety and efficacy of upper limb access for f/b-EVAR, with low stroke risk, mortality rates, and minimal local complications. Despite the risk of bias, the findings suggest that upper limb access may be beneficial, especially in bailout situations when femoral access fails, offering valuable insights for clinical decision-making.

The incidence of T4b esophageal cancer with aortic invasion but without distant metastasis is estimated to be between 3.8% and 4.6% of all esophageal cancer cases. Development of an aortoesophageal fistula in such cases is a rare but not unlikely event, leading to catastrophic consequences. The aim of this systematic review is to evaluate the importance of aortic stenting (Thoracic Endovascular Aortic Repair-TEVAR) and its optimal timing in the management of locally advanced esophageal cancer. A systematic literature search of the MEDLINE, Scopus, and Google Scholar databases was undertaken to identify relevant studies published up to March 2024. An individual patient data analysis was performed by forming a patient cohort with elective and salvage TEVAR subgroups, depending on the timing of the stenting. The study pool consisted of 25 studies incorporating 101 cases of locally advanced esophageal cancer, with a median age of 64 years (range 45-87 years). Of them, 50 patients underwent elective TEVAR compared with 51 patients receiving TEVAR in an acute salvage setting. Elective or prophylactic TEVAR was found to significantly increase esophageal resection rates (65.6% vs. 16.7% in the salvage subgroup, P < 0.001), concurrently reducing complication rates (8.3% vs. 36.1%, P < 0.001). Overall survival was also prolonged in the elective subgroup (8.3 vs. 4 months, P = 0.001), with elective stenting being the only independent predictor of improved survival. In conclusion, management with aortic stenting in high-risk patients may reduce the catastrophic consequences of massive bleeding, minimize complications, and enhance survival rates.

BACKGROUND: Although renal artery aneurysms (RAAs) are rare and often asymptomatic with slow growth, their natural progression and optimal management are not well understood. Treatment recommendations for RAAs do exist; however, they are supported by limited data.
METHODS: A retrospective cohort study was conducted to explore the management of patients diagnosed with an RAA at our institution from January 1st, 2013, to December 31st, 2020. Patients were identified through a search of our radiological database, followed by a comprehensive chart review for further assessment. Data collection encompassed patient and aneurysm characteristics, the rationale for initial imaging, treatment, surveillance, and all-cause mortality.
RESULTS: One hundred eighty-five patients were diagnosed with or treated for RAAs at our center during this timeframe, with most aneurysms having been discovered incidentally. Average aneurysm size was 1.40 cm (±0.05). Of those treated, the mean size was 2.38 cm (±0.24). Among aneurysms larger than 3 cm in size, comprising 3.24% of the total cases, 83.3% underwent treatment procedures. Only 20% of women of childbearing age received treatment for their aneurysms. There was one instance of aneurysm rupture, with no associated mortality or significant morbidity.
CONCLUSIONS: Our institution\'s management of RAAs over the period of the study generally aligned with guidelines. One potential area of improvement is more proactive intervention for women of childbearing age.

BACKGROUND: Innominate artery aneurysms (IAAs) are rare and may result in rupture, distal arterial embolization, or local compression without timely treatment. Rupture is the most dangerous of these complications. This article reports a case of innominate artery bifurcation pseudoaneurysm.
METHODS: The patient was a 45-year-old man who was admitted to the emergency department due to chest discomfort. The computed tomographic angiography (CTA) imaging indicated the presence of a 3.6*2.4 cm saccular aneurysm in the bifurcation of the innominate artery, involving both the right proximal subclavian and common carotid arteries. The patient\'s vital signs were normal, there was equal blood pressure in the upper arms and no neurological dysfunction was observed. Gadolinium-enhanced magnetic resonance angiography indicated that the circle of Willis was intact. The treatment involved open surgery combined with endovascular therapy. The external carotid artery was first transposed to the right subclavian artery (RSA) and an 8-mm woven Dacron graft was inserted in the middle. The covered stent graft was then placed in the proximal part of the innominate artery to close the entrance of the aneurysm. Lastly, an occluder was implanted at the origin of the RSA. There were no perioperative or postoperative complications. At 1-year follow-up, no aneurysm was observed on CTA and the right vertebral artery was patent.
CONCLUSIONS: This study indicated that the combined use of endovascular therapy and open repair surgery is an effective strategy to treat innominate artery bifurcation pseudoaneurysm.

BACKGROUND: Blunt traumatic aortic injury (BTAI) is the second leading cause of death due to traumas in young patients. The primary presentation might be chest or interscapular pain, difficulty in breathing, and, in severe cases, hypotension. Considering the rapid deterioration of these patients\' clinical conditions, prompt diagnosis and treatment initiation are crucial. In these injuries, the most involved parts of the aorta are the isthmus (distal to the left subclavian artery) and the descending part in the thorax. Therefore, the main diagnostic strategies include transthoracic echocardiography, CT angiography, and endovascular diagnostic approaches. Case presentation The patient was a 19-year-old male presenting with the symptoms of chest pain, dyspnea, and extremities excruciating pain after a car turnover. The initial evaluation showed no abnormal cardiovascular finding except bilateral hemothorax, addressed with chest tubes. Twelve hours later, when the patient was under observation for orthopedic surgeries, his chest pain and dyspnea started, and TTE and CTA showed a grade three descending aneurysm of the aorta. The patient was treated immediately with an endovascular procedure of stent implantation. A delayed debranching surgery was also performed, which resulted in desirable outcomes and uneventful follow-up.
CONCLUSIONS: Although open thoracic surgery is the main and almost the only option for treating aneurysms of the aorta in hemodynamically unstable patients, the endovascular procedure has shown superior outcomes in selected patients with appropriate anatomy. Debranching surgery, which can be done simultaneously or with delay after the initial procedure, has proven protective against thromboembolic cerebral events.
UNASSIGNED: Patients with an aneurysm of the aorta should be transported to a medical center with a multidisciplinary team for an urgent evaluation and treatment. The initial resuscitation and diagnosis are challenging, considering the fatal nature of these injuries, and the selection of the treatment is based on the patient\'s clinical condition and evaluated anatomy in cardiovascular imaging.
