We present a case of a 4.2-cm hepatic artery aneurysm following remote pancreaticoduodenectomy, which extended to the first division of the right hepatic artery. Given the absence of collateral flow from the superior mesenteric artery (SMA) and the inability to place a covered stent, we treated the patient with a saphenous vein graft to the right hepatic artery bifurcation. A CT scan at 1-year demonstrated a patent bypass to the right hepatic artery. We would advise caution when considering hepatic embolization following pancreaticoduodenectomy due to loss of SMA-based collaterals. Techniques that preserve arterial flow should be favored in this situation.

Infected abdominal aortic aneurysms (AAAs) make up a small minority of AAAs yet are characterized by a high fatality rate, largely attributed to their increased risk of aneurysm rupture. This case details a rare presentation of a 56-year-old man that developed Proteus mirabilis bacteremia secondary to a perineal abscess and subsequently experienced a 3 cm growth of his previously stable AAA over an 8 day period. This case underscores the importance of maintaining a heightened suspicion for infected aortic aneurysms in sick patients and highlights the critical role of surgical management in achieving source control.

OBJECTIVE: To evaluate the current evidence and literature on treatment options for proximal hamstring injuries.
RESULTS: Patients with 3-tendon complete tears with greater than 2 cm of retraction have worse outcomes and higher complication rates compared to those with less severe injuries. Endoscopic and open proximal hamstring repair both have favorable patient reported outcomes at 5-year follow up. Proximal hamstring repair in patients who are male, with isolated semimembranosus injury, and have proximal hamstring free tendon rupture are more likely to have earlier return to sports. The Parisian Hamstring Avulsion Score (PHAS) is a validated patient-reported outcome measure to predict return to sports. Proximal hamstring injuries may occur in both elite and recreational athletes and may present with varying degrees of chronicity and severity. Injuries occur most commonly during forceful eccentric contraction of the hamstrings and often present with ischial tuberosity tenderness, ecchymosis, and hamstring weakness. Treatment decision-making is dictated by the tendons involved and chronicity. Many proximal hamstring injuries can be successfully treated with non-surgical measures. However, operative treatment of appropriately indicated proximal hamstring tendon injuries can result in significantly better functional outcomes and faster and more reliable return to sports compared to nonoperative treatment. Both endoscopic and open surgical repair techniques show high satisfaction levels and excellent patient-reported outcomes at short- and mid-term follow-up. Postoperative rehabilitation protocols vary across the literature and ongoing study is needed to clarify the optimal program, though emphasis on eccentric hamstring strengthening may be beneficial.

We report the case of a 77-year-old woman presenting with an asymptomatic internal carotid artery (ICA) aneurysm arising at the skull base. The distal right extracranial ICA aneurysm presented as a challenging case due to difficulty in obtaining adequate surgical exposure and preserving the facial nerves present near the ICA aneurysm. Transcervical open repair with a team of vascular and otolaryngology surgeons was completed successfully. In this report, we detail the operative steps needed to complete this exposure and our perioperative management.

BACKGROUND: Ventral hernia repair underwent various developments in the previous decade. Laparoscopic primary ventral hernia repair may be an alternative to open repair since it prevents large abdominal incisions. However, whether laparoscopy improves clinical outcomes has not been systematically assessed.
OBJECTIVE: The aim is to compare the clinical outcomes of the laparoscopic versus open approach of primary ventral hernias.
METHODS: A systematic search of MEDLINE (PubMed), Scopus, Web of Science, and Cochrane Central Register of Controlled Trials was conducted in February 2023. All randomized controlled trials comparing laparoscopy with the open approach in patients with a primary ventral hernia were included. A fixed-effects meta-analysis of risk ratios was performed for hernia recurrence, local infection, wound dehiscence, and local seroma. Meta-analysis for weighted mean differences was performed for postoperative pain, duration of surgery, length of hospital stay, and time until return to work.
RESULTS: Nine studies were included in the systematic review and meta-analysis. The overall hernia recurrence was twice less likely to occur in laparoscopy (RR = 0.49; 95%CI = 0.32-0.74; p < 0.001; I2 = 29%). Local infection (RR = 0.30; 95%CI = 0.19-0.49; p < 0.001; I2 = 0%), wound dehiscence (RR = 0.08; 95%CI = 0.02-0.32; p < 0.001; I2 = 0%), and local seroma (RR = 0.34; 95%CI = 0.19-0.59; p < 0.001; I2 = 14%) were also significantly less likely in patients undergoing laparoscopy. Severe heterogeneity was obtained when pooling data on postoperative pain, duration of surgery, length of hospital stay, and time until return to work.
CONCLUSIONS: The results of available studies are controversial and have a high risk of bias, small sample sizes, and no well-defined protocols. However, the laparoscopic approach seems associated with a lower frequency of hernia recurrence, local infection, wound dehiscence, and local seroma.

BACKGROUND: Congenital diaphragmatic hernia (CDH) repair can be challenging, particularly when a larger defect is present. Barbed sutures prevent the suture from slipping back after approximation of the tissues. Although introduced almost 2 decades ago, barbed sutures have not been widely used for CDH repair. We report our initial experience and pitfalls.
METHODS: All patients presenting with CDH from 2021 onward underwent repair using barbed sutures. Demographics, operative parameters, complications, and outcomes were prospectively recorded.
RESULTS: A total of 13 patients underwent CDH repair during the study interval (median age 6 days, range 3 days to 5.75 years). Median operative time was 89 min (range 46 to 288 min). Five thoracoscopic and eight open procedures were performed. Severe pulmonary hypertension and ECMO (extracorporeal membrane oxygenation) were considered contraindications for thoracoscopic repair. The included patients were compared to a historic controlled group performed without barbed sutures. The barbed suture facilitated easy and quick closure of the defects in most cases and obviated the need for knot tying. One patient in the thoracoscopic group had a patch placed due to high tension after the barbed sutures tore the diaphragm. At a median follow-up time of 15 months (range 2 to 34 months), one patient had died, and one patient with complete diaphragmatic agenesis was home-ventilated. There were no recurrences. Median operative time trended lower (89 min) than in the historic control group repaired without barbed sutures (119 min, p < 0.06) after eliminating outliers with large, complex patch repairs.
CONCLUSIONS: Barbed sutures simplify congenital diaphragmatic hernia repair regardless of whether a minimal-invasive or open approach is performed. Patch repair is not a contraindication for using barbed sutures. The resulting potential time savings make them particularly useful in patients with cardiac or other severe co-morbidities in which shorter operative times are essential. In cases with high tension, though, the barbs may tear through and produce a \"saw\" effect on the tissue with subsequent damage.

UNASSIGNED: The introduction of endovascular repair provides an alternative to traditional open repair of thoracoabdominal aortic aneurysms (TAAA). Its utility is not well defined, however. Using a national database, we studied the treatment patterns and outcomes of TAAA to gain insight into its contemporary surgical practice in the United States.
UNASSIGNED: Records of TAAA patients who received endovascular and open repair were retrieved from the 2002 to 2018 National Inpatient Sample database. Each cohort was stratified into 4 age groups: ≤50, 51 to 60, 61 to 70, and >70 years. Patient characteristics and in-hospital outcomes were compared between the 2 repair modalities. Temporal trends were investigated.
UNASSIGNED: Endovascular repair use increased steadily, whereas open repair volume remained stable until 2012, before declining by 50% by 2018. This appears to be associated with a declining number of open repairs in patients age >60 years. Patients who underwent endovascular repair were older and had a higher Charlson Comorbidity Index (mean, 2.8 ± 1.7 vs 2.5 ± 1.5; P < .001) but lower in-hospital mortality (mean, 8.9% vs 17.1%; P < .001), shorter length of stay (mean, 10.1 ± 12.2 days vs 17.1 ± 17.4 days; P < .001), and fewer postoperative complications. A difference in mortality between open and endovascular repair was observed for patients age >60 years but not for patients age ≤60 years.
UNASSIGNED: There has been a shift in the treatment of TAAA in the United States from open repair-dominant to endovascular repair-dominant. It has increased surgical access for older and more comorbid patients and has led to a decline in the use of open repair while lowering in-hospital mortality.

UNASSIGNED: Primary aortic thrombus (PAT) in the absence of underlying aortic pathology such as atherosclerosis or aneurysm is quite rare and presents with various symptoms related to distal embolization. Treatment options include anticoagulation alone, open surgical thrombectomy, endovascular repair, and a combination of these approaches. The optimal management strategy remains controversial.
UNASSIGNED: Between 2016 and 2020, 10 patients (6 females; mean age, 49.1 years) presented to our institution with PAT in the thoracic aorta. All 10 patients were active tobacco users, and 6 patients were found to have an underlying hypercoagulable state. Locations of the PAT included the ascending aorta in 4 patients, the descending thoracic aorta in 3 patients, and the aortic root, aortic arch, and thoracoabdominal aorta in 1 patient each. At presentation, 2 patients had developed myocardial infarction, and 2 others had cerebral infarction. All patients but 1, who was managed medically for PAT, underwent open surgical thrombectomy via either sternotomy or left thoracotomy. Concomitant procedures included coronary artery bypass grafting in 2 patients and pulmonary thromboembolectomy in 1 patient. There were no operative deaths. During a median follow-up of 18 months, 2 patients developed recurrent PAT, owing primarily to poor compliance with anticoagulation. One patient required redo open thrombectomy. Two patients had mesenteric ischemia necessitating small bowel resection.
UNASSIGNED: Open surgical thrombectomy of the thoracic aorta can be performed with low mortality and morbidity; however, PAT can recur, especially in patients who have difficulty managing anticoagulation.

New-onset acute type B aortic dissection after prior endovascular aneurysm repair is extremely rare. Extension of an aortic dissection can cause destabilization of the previously implanted stent graft, thrombosis of the stent graft, and rupture of the aneurysmal sac, with high mortality without therapy. This report describes the case of a 66-year-old patient complaining of sudden abdominal pain radiating to both flanks. Computed tomography angiography of the aorta revealed acute type B aortic dissection with infrarenal rupture of the false lumen after endovascular abdominal aneurysm repair 5 years prior. The patient underwent infrarenal open surgical conversion with suprarenal aortic clamping and implantation of a bifurcated Dacron graft. Postoperatively, no serious complications resulted from the treatment, except for fascial dehiscence. In such cases, the patients can be treated in an emergency situation with open repair, despite the high risk of complications and mortality.

Several options exist for the treatment of celiac artery (CA) aneurysms (CAAs), including surgical repair and endovascular procedures. However, treatment of CAAs can be challenging owing to their proximity to the ostium of the CA and involvement of the CA branches. In the present report, we have described a case of a giant CAA extending from the proximal CA to the hepatosplenic bifurcation. Owing to the anatomic complexity of this CAA, proximal control was a major therapeutic concern. The patient underwent open aneurysmectomy using the retrograde balloon occlusion technique to control the inflow of the CAA, with a satisfactory result.
