This retrospective study was conducted to analyze a new concept of evaluation of the effect of distal runoff on patency in infrainguinal bypass surgery for arterial insufficiency. Distal runoff was evaluated on postreconstruction angiograms in 191 limbs undergoing femoropopliteal and femorodistal reconstruction. Runoff was characterized as good, fair, or poor. Determination of graft patency was made by clinical examination, ankle-brachial index measurement, or duplex scanning at 1 month and thereafter at 6-month intervals. Cumulative patency rates were calculated according to the actuarial life table method. Patency rates in limbs with good runoff were better than in limbs with fair and poor runoff; at 6 months, patency rates were 88.2%, 70.9%, and 21.8%, respectively (p < 0.01). Similar patency rates were found for good runoff in femoropopliteal and femorodistal reconstructions (84.7% in femoropopliteal and 75% in femorodistal reconstructions) at 6 months. The authors conclude that this method of angiographic evaluation accurately predicts patency in infrainguinal bypass reconstructions.

Background And Hypothesis: Efficient arteriovenous access (VA) surveillance is vital for early identification of dysfunctional access, allowing timely intervention to prevent thrombosis. This study compares the efficacy of adding remote software surveillance to standard clinical care across our units.
Methods: We conducted a 12-month prospective study on maintenance hemodialysis (HD) patients using Vasc-Alert software technology to assist clinical decision-making in 2 satellite HD units (Group 1) and standard care in the remaining 3 HD units (Group 2) .

Purpose: Portal vein tumor thrombus (PVTT)-related severe symptomatic portal hypertension (SPH) leads to a poor prognosis in patients with advanced hepatocellular carcinoma (HCC). Traditional transjugular intrahepatic portosystemic shunt (TIPS) using covered plus bare stent can effectively relieve SPH, however, the bare segment is susceptible to obstruction due to PVTT invasion. This study aimed to evaluate the safety and efficacy of fully covered stent-TIPS (FCS-TIPS) for treatment of PVTT-related SPH in advanced HCC patients.

Background: Catheter-related right atrial thrombus (CRAT) is a severe complication in hemodialysis patients that can lead to catheter dysfunction and pulmonary embolism (PE). However, no standardized treatment strategy currently exists for hemodialysis-related CRAT. This study aims to investigate the efficacy of catheter replacement and antiplatelet therapy in managing hemodialysis CRAT.

Background: Superficial temporal artery (STA)-middle cerebral artery (MCA) side-to-side microvascular anastomosis can achieve the same clinical effects as traditional STA-MCA end-to-side anastomosis in extracranial-intracranial revascularization surgery, furthermore, STA-MCA side-to-side anastomosis has the lower risk of postoperative cerebral hyperperfusion syndrome (CHS) and the potential to recruit all scalp arteries as the donor sources via self-regulation. Therefore, STA-MCA side-to-side microvascular anastomosis seems to be a revascularization strategy superior to traditional STA-MCA end-to-side anastomosis. In this study, we presented seven cases in which a STA-MCA side-to-side microvascular anastomosis was performed with a 4-5 mm long arteriotomy using the in-situ intraluminal suturing technique.

Objective: Superior vena cava syndrome (SVC) is a debilitating disease, and surgical reconstruction has been described with some of the best results using spiral great saphenous vein (SGSV) grafts. SGSV grafts can be difficult to construct, and a long segment of saphenous vein is needed. Femoral vein has been an excellent conduit for infected aortic and peripheral reconstructions in our hands, and we sought to review outcomes using this conduit for SVC reconstruction.
