UNASSIGNED: There is great variability in the treatment of chronic limb-threatening ischemia, including the practice paradigm, vascular provider specialty, devices utilized, and experience with advanced open and/or endovascular treatments, among other factors. Our unique practice consists of patient-centered, clinically oriented Interventional Radiologists and Vascular Surgeons, with treatments being performed in Office Interventional Suites (OIS), Ambulatory surgery center (ASC), and hospital inpatient/outpatient settings. We evaluate our results, centered on major amputation rates while comparing case complexity and rates with previously published data.
UNASSIGNED: A retrospective review was performed of all Rutherford 4, 5, and 6 patients who underwent treatment in our practice from 2015 to 2021. Baseline patient characteristics, complexity of lesions, and major amputation rates were collected. Patients with more complex diseases or requiring re-interventions were openly discussed in multidisciplinary fashion to determine the group\'s approach to revascularization. Limb salvage, clinically driven target lesion revascularization (TLR), repeat interventions, length of follow-up, and mortality were assessed.
UNASSIGNED: Treatment was performed in 829 limbs in 351 females and 478 males, with chronic limb-threatening ischemia. Of the 829 cases, 541 cases had at least 1 chronic total occlusion (CTO), including 115 limbs with 2 CTOs and 24 limbs with 3 CTOs with 63.5% of cases requiring multilevel intervention. One year mortality rate was 6.2% with a major lower extremity amputation rate of 2.3% with a mean length of follow-up of 22.3 months. One-year freedom from clinically driven TLR rate was 78.7% with repeat intervention in 163 cases within 12 months. Over the course of the study, within the femoropopliteal stent subset, there was a significant increase in time to reintervention when newer stent technologies were utilized such as woven nitinol and drug-eluting technology (p=0.03). The overall 1-year amputation-free survival (AFS) was 91.5.
UNASSIGNED: Multidisciplinary approach with surgical and endovascular treatment may provide patients with the best chance of AFS.
CONCLUSIONS: Real world practice of critical limb-threatening ischemia in a multidisciplinary practice demonstrates favorable outcomes for patients with the best reported one year major amputation free survival in a population this large. A strong clinical practice based on close routine follow up and arterial duplex monitoring is a major contributing factor, as well as utilization of the latest technology in drug eluting stents and drug coated balloons for best patient outcomes. We hope this study provides other practices with a guideline for establishing or modifying their practice to attain the best procedural and clinical outcomes.

Spontaneous celiac artery dissection is uncommon. Abdominal pain is a common clinical presentation. Conservative medical treatments, endovascular interventions, and open surgery are used to treat spontaneous celiac artery dissection. A 49-year-old male patient visited our hospital, with back and subxiphoid pain that had persisted for 11 hours. He has been smoking 40 cigarettes a day for 20 years. The blood pressure was 180/100mmHg. Aortic computed tomography angiography (CTA) images revealed dissection of the celiac artery, common hepatic artery, left hepatic artery, right hepatic artery, and splenic artery. Urapidil hydrochloride and isosorbide dinitrate were administered to lower the blood pressure to approximately 110/70 mmHg. However, the back and subxiphoid pain persisted without relief. Angiography was performed and a vascular stent (BARD, LIFE STENT, VASCULAR, 8 × 60) was implanted into the celiac artery without involving the branches. Pain was immediately relieved after interventional therapy. The patient was discharged after 4 days. A subsequent aortic CTA after 10 months confirmed that the celiac artery dissection had still not reoccurred.

Aortic dissection is a critical and life-threatening condition that can present with atypical symptoms, often leading to misdiagnosis and delayed treatment. The report presents a case of a 65-year-old male who initially exhibited fever, right-sided chest pain, and a productive cough, resulting in an initial diagnosis of pneumonia. Despite empirical antibiotic therapy, his symptoms persisted, prompting further investigation. A computed tomography (CT) scan ultimately revealed a Type B aortic dissection. The patient was then transferred to a specialized tertiary care facility for successful endovascular intervention. This case underscores the importance of considering aortic dissection in patients presenting with persistent, atypical symptoms that do not respond to standard treatments, such as unexplained fever and chest pain. It highlights the crucial role of advanced imaging techniques, such as CT scans, in achieving an accurate and timely diagnosis. Clinicians must maintain a high index of suspicion and ensure prompt referral to specialized centers to improve patient outcomes in this potentially fatal condition.

OBJECTIVE: Popliteal access (PA) as an alternative to conventional femoral access has not been reported in the office-based catheter laboratory setting (OBL) and may be perceived to have higher risks. The purpose of this study is to evaluate the safety and efficacy of popliteal access for endovascular treatment of iliofemoral arterial occlusive disease in an OBL setting.
METHODS: From 10/2018 - 10/2023 a total of 1,408 PAD interventions were performed in our OBL. A cohort of 27 popliteal access consecutive procedures for femoral and iliac artery occlusions were studied. All interventions were done using a micro-puncture needle under ultrasound guidance. All patients were discharged 1 hour after completion of the procedure. Indications for popliteal access were presence of aortoiliac stent/grafts, aorto-bifemoral or aortoiliac bypasses, difficult contralateral or antegrade femoral access, and flush superficial femoral artery (SFA) occlusions. Procedures were determined to be successful upon complete resolution of the target lesions and safety was measured peri-operatively and at 90-days. Patency was determined clinically, by arterial duplex, and by need for reintervention up to 2 years.
RESULTS: 27 popliteal access procedures were performed in 25 patients (21 complete femoral artery occlusions, 6 severe stenosis). Iliac disease was present in 9. Indications for PA were existing aortoiliac stent graft 11, aorto-bifem-iliac bypass 4, non-crossable iliac occlusions 3, failed antegrade femoral access 4, flush SFA occlusion 3, and bilateral common femoral artery disease precluding access 2. TASC pre-op was B: 4, C: 4, D:19. Treatments included atherectomy/balloon angioplasty (BA) and stent 12, BA and stenting 4, atherectomy/BA 5, BA alone 6. Successful opening of occlusions occurred in 25/27 (92.5%). No complications or major adverse cardiac events (MACE) occurred except 1 asymptomatic small popliteal AV fistula. Of the 25 successful procedures duplex patency at 3, 6 & 12 months was 19/20 (95%), 11/15 (69.3%) & 11/13 (61%). Rutherford Classification improved from pre-op > 4 in 24/27 (89%) to post-op < 2 at 1 month in 23/23 (100%), 3 months in 19/20 (95%), 6 months in 11/15 (69.3%), 12 months in 11/13 (61%). Freedom from re-intervention at 3 months in 19/20 (95%), 6 months in 13/15 (86%), and 12 months in 12/13 (79%).
CONCLUSIONS: Popliteal artery access for complex iliofemoral disease is safe and effective and should be considered as a valid alternative option in the OBL setting.

BACKGROUND: Patients with symptomatic chronic internal carotid artery occlusion (ICAO) face a high risk of recurrent stroke despite receiving aggressive medical therapy. This study aimed to evaluate the effectiveness and safety of hybrid surgery in treating symptomatic chronic ICAO.
METHODS: This retrospective case series was conducted at a single center. From January 2019 to December 2022, patients with symptomatic chronic ICAO who underwent hybrid surgery were included. We collected baseline data, lesion characteristics, revascularization rates, perioperative complications, and follow-up outcomes.
RESULTS: The study enrolled 27 patients, comprising 22 males and 5 females, with symptomatic chronic ICAO. The hybrid surgery achieved a technical success rate of 100% for revascularization (n = 27), with a perioperative complication rate of 14.8% (n = 4). Following a median follow-up of 6.0 months (IQR, 4-10), 21 patients underwent a DSA or CT angiography reexamination, confirming a vascular patency rate of 90.5% (n = 19). One patient required surgery for severe in-stent restenosis, and another experienced asymptomatic occlusion. Clinical follow-ups were conducted for all 26 patients; no new strokes were reported in the qualifying artery territory, with 13 patients scoring 0, 12 scoring 1, and 1 scoring 2 on the mRS.
CONCLUSIONS: Although hybrid surgery represent a promising option for treating chronic ICAO, they are also associated with a relatively high incidence of treatment-related complications. The application of composite surgery should be based on standardized technical guidelines and the careful selection of patients who are genuinely at high risk for recurrent strokes.

OBJECTIVE: Chronic lower limb ischaemia is a peripheral arterial disease (PAD) which is typically instigated by atherosclerotic plaques in the peripheral vasculature. This article reports on a unique case of chronic ischaemia in the lower limb, presenting in a distinctive manner as a fungal toenail infection.
METHODS: An 82-year-old frail woman with multimorbidity presented with toenail symptoms in her right foot. While initial examination had shown onychomycosis, further investigation was unexpectedly consistent with chronic ischaemia in the lower limb. We explored the clinical presentation, diagnostic challenges encountered, and the subsequent management of this unique manifestation in the context of the patient\'s multimorbidity.
CONCLUSIONS: This case report highlights the need to consider chronic limb ischemia as a differential diagnosis in toenail infections when no alternative causes or predisposing factors are identified.

UNASSIGNED: The role of atherectomy in treating femoropopliteal disease has been evolving rapidly. However, the clinical efficacy and safety of adjunctive atherectomy to percutaneous balloon angioplasty (BA) (plain balloon and drug-coated BA) remains controversial. We sought to perform a meta-analysis comparing atherectomy plus balloon angioplasty (ABA) versus BA alone in treating femoropopliteal disease.
UNASSIGNED: We searched PubMed, Cochrane Central Register of Clinical Trials, EMBASE, and ClinicalTrials.gov (from inception through January 10, 2022) for studies comparing ABA versus BA for femoropopliteal disease. We used a random-effects model to calculate risk ratio (RR) with 95% CIs. Target lesion revascularization (TLR), primary patency, and bailout stenting were the primary outcomes.
UNASSIGNED: Nine studies with 699 patients were included (4 randomized and 5 retrospective studies). Compared to BA alone, the ABA group showed a significant decrease in TLR driven by nonrandomized studies (RR 0.59; 95% CI, 0.40-0.85; P = .005) and bailout stenting (RR, 0.32; 95% CI, 0.21-0.48; P < .0001). There was no significant difference in TLR when the analysis was performed including only randomized trials. There was no significant difference in the primary patency between the 2 groups (RR, 1.04; 95% CI, 0.95-1.14; P = .37).
UNASSIGNED: Data from randomized trials suggest that compared with BA alone, the combination of atherectomy and BA showed no difference in TLR or primary patency. In observational studies, TLR and bailout stenting were reduced in ABA group but there was no difference in primary patency. Further studies are needed to investigate the clinical outcomes of atherectomy combined with BA in femoropopliteal lesions compared with BA alone.

İnternal carotid artery (ICA) aneurysms are rare but they can cause high morbidity and mortality. Although these aneurysms are usually asymptomatic, they can reach huge sizes and compress the surrounding neurovascular structures. Patients typically present with neurologic symptoms due to cranial nerve compression. If they rupture, they can lead to massive epistaxis and autorage. In physical examination, pulsatile mass in the middle ear or nasal cavity can be seen. If there is a clinical suspicion of an ICA aneurysms, diagnostic radiological imaging should be performed before the surgical procedure or biopsy. Cerebral digital subtraction angiography (DSA) should be performed for definitive diagnosis. After diagnosis, appropriate endovascular or open intervention should be performed. In this case report, we present a 48-year-old female patient with severe epistaxis complaint due to an ICA aneurysm. This report aims to present this case and review the current literature.
