Background: Advancement in endovascular techniques has led to rapid growth in endovascular revascularization, and it has emerged as a treatment for critical limb ischemia (CLI). Clinical effectiveness of revascularization has been frequently judged by vessel patency and limb salvage, but there is paucity of reports on outcomes of the wound. We present a retrospective analysis of immediate angiographic and 3-month clinical outcome of patients who underwent endovascular reconstruction of popliteal and infrapopliteal arteries for CLI.
Methods: All patients who underwent endovascular reconstruction of popliteal and/or infrapopliteal arteries for CLI and >70% stenosis on digital subtraction angiography between March 2010 and November 2014 and had a clinical follow-up of at least 3 months were selected for analysis.
Results: 34 patients underwent endovascular reconstruction. 9 patients (26%) underwent only POBA and remaining 25 (74%) underwent additional stenting. 13 patients (38%) had multiple segmental revascularization. 24 patients (71%) had successful vessel recanalization. Linear flow to foot in at least one artery could be achieved in 20 patients (59%) post revascularization. Successful wound healing occurred in 11 (35%) patients with an additional 7 (21%) patients showing clinical improvement in their wounds. Limb salvage was achieved in 33 patients (97%) at 3-month follow-up.
Conclusion: Endovascular revascularization of popliteal and infrapopliteal arteries is a feasible, safe, and effective procedure for the treatment of CLI. Normal inflow and outflow with at least one of the three infrapopliteal vessels being patent is essential for adequate healing of chronic ulcers and prevention of major amputation.

Background: Flow diverters (FDs) have been introduced for the management of large or giant cavernous carotid aneurysms (CCAs) in addition to conventional modalities, dramatically changing treatment strategies. The aim of this study was to examine the management of unruptured large/giant CCAs in Japan when FDs were being introduced using a nationwide survey.
Methods: 540 unruptured large/giant CCAs treated at neurosurgical teaching departments in Japan between 2012 and 2016 were retrospectively studied.

Objective: Popliteal artery injury is a rare but serious complication of arthroscopic knee surgery. The absence of comprehensive data and standardized guidelines underscores the urgent need for further investigation. This study examines the incidence, risk factors, management strategies, and long-term outcomes of popliteal artery injury in the context of arthroscopic knee procedures.

Background: Multidisciplinary care with vascular surgery and plastic surgery is essential for lower extremity free flap (LEFF) success in the chronic wound population with diabetes and peripheral vascular disease. There is a lack of understanding on performing targeted direct endovascular reperfusion on a vessel that will be used as the flap recipient. Our study compares outcomes of patients who received targeted revascularization (TR) to the recipient vessel for LEFF anastomosis versus nontargeted revascularization (NR) of arterial recipients prior to LEFF.

The Purpose: Evaluation of the short-term and long-term results of a phased correction of the tetralogy of Fallot (ToF) with stenting of the right ventricular outflow tract (RVOT) in comparison with a one-stage total correction (TC) of the defect.
Materials And Methods: Two groups of patients with classical ToF were formed. Group 1 (n = 25; median age = 72 days) was initially represented by children with ToF with a more severe clinical status (median weight = 3.

A superior mesenteric arteriovenous fistula (SMAVF) following gastrointestinal surgery represents a rare vascular complication. Enhanced computed tomography with 3-dimensional reconstruction proves to be the most efficacious modality for detecting this uncommon entity. Superior mesenteric angiography becomes imperative to accurately delineate the location and extent of mesenteric vessel involvement, which is essential for devising an optimal treatment strategy.
