Objective: The aim of this non-inferiority randomised trial was to compare the short and midterm safety and efficacy of hybrid repair (HR) and open reconstruction (OR) for patients with co-existing iliac and common femoral artery (CFA) occlusive disease.
Methods: The study was registered on the ClinicalTrials.gov register (identifier: NCT02580084). From 2015 to 2017, eligible patients presenting with combined iliac and CFA occlusive disease were randomised to either HR or OR. HR group patients underwent recanalisation and stenting of iliac arteries combined with CFA endarterectomy and patch angioplasty. The OR group underwent aortofemoral bypass with simultaneous CFA endarterectomy. Short (30 day) and midterm (36 month) outcomes including morbidity, mortality, and patency rates were compared between groups.
Results: Of 427 patients assessed, 202 were randomised (102 HR and 100 OR). The average hospital length of stay was shorter in the HR group (8.2 ± 4.2 days HR group vs. 15.7 ± 6.9 days OR group, p < .001); the 30 day peri-operative morbidity rate was 8.8% in the HR group vs. 21% in the OR group (p = .030). There was no significant difference in the 36 month mortality rate (p = .16). The cumulative primary patency rates were 93% (HR) vs. 93% (OR) at 12 months and 91% (HR) vs. 89% (OR) at 36 months (p = .38). The limb salvage rates were 99% (HR) vs. 99% (OR) at 12 months and 98% (HR) vs. 97% (OR) at 36 months (p = .49).
Conclusion: The results of this first non-inferiority randomised study support the safety and midterm efficacy of hybrid procedures for patients with iliofemoral peripheral arterial disease. HR patients had a shorter length of stay with reduced peri-operative morbidity and similar medium term patency rates.

Navigating complex arterial reconstruction in living donor liver transplantation: the role of the splenic artery as a viable conduit.
BMC Surg
January 2025
Liver Transplant Unit, Gastrointestinal Surgical Center (GISC), Surgery Department, Mansoura University, Mansoura, Dakahleyya, Egypt.
Background: In living donor liver transplantation (LDLT), maintaining hepatic arterial flow is critical for graft survival. Alternative methods are required when the recipient's hepatic artery is unsuitable due to extensive dissection or inadequate flow. This study evaluates the efficacy and safety of splenic artery transposition (SAT) for hepatic arterial reconstruction in LDLT.

Ann Otol Rhinol Laryngol
January 2025
Department of Otolaryngology-Head and Neck Surgery, University Hospitals Cleveland Medical Center, Cleveland, OH, USA.
Objectives: The primary objective of this case series is to assess the effectiveness of the off-label use of the PROPEL drug-eluting stent, traditionally FDA-approved for sinus surgery, in preventing restenosis following canalplasty in patients with chronic otologic conditions or congenital anomalies. The stent provides both mechanical support to maintain canal patency and localized steroid delivery to reduce inflammation and scarring.
Methods: Four patients with various otologic conditions underwent canalplasty, followed by the placement of drug-eluting stents into the external auditory canal.
Long-term Patency and Complications of Endovascular and Surgical Revascularization for Takayasu Arteritis.
Vasc Specialist Int
December 2024
Division of Vascular Surgery, Department of Surgery, Seoul National University College of Medicine, Seoul, Korea.
Purpose: Takayasu arteritis (TAK) is a rare form of chronic vasculitis that is common in Asian female. As TAK predominantly affects young female with a longer life expectancy than those with atherosclerotic diseases, assessing the specific long-term outcomes of TAK treatment is important. Therefore, this study aimed to evaluate the long-term outcomes and post-procedural complications of surgical and endovascular treatment for TAK.

Background: Vasectomy reversal (VR) is the only technique that allows men previously submitted to a vasectomy to conceive by natural pregnancy. We report our experience with microsurgical VR and identify predictive factors of natural pregnancy.
Methods: We retrospectively reviewed all patients submitted to VR by a single surgeon from 2008 to 2021 at our single center.
Endoscopic Vein Harvest Is Associated with Worse but Improving Outcomes in Infrainguinal Bypass.
J Vasc Surg
December 2024
Division of Vascular Surgery, Department of Surgery, Henry Ford Hospital, Detroit, USA. Electronic address:
Objective: The impact of great saphenous vein harvest technique on infrainguinal bypass outcomes remains a matter of debate, with no robust evidence favoring a specific technique over the other. This study aims to compare the outcomes of open vein harvest with endoscopic vein harvest in patients undergoing infrainguinal bypass surgery.
Methods: Patients who underwent an infrainguinal bypass from a femoral origin using a single-segment great saphenous vein between 2011 and 2023 were identified in the Vascular Quality Initiative infrainguinal bypass module.
