Objectives: to report the long term results of remote superficial femoral artery endarterectomy (RSFAE) with the MollRing Cutter for the treatment of long segmental SFA occlusive disease.
Design: retrospective open study.
Patients And Methods: from March 1994 to August 2000 183 RSFAEs were performed in 164 selected patients (105 males, 120 procedures) with a median age of 63 years (43-84 years). Indications for operation were disabling intermittent claudication in 129 procedures (70%), rest pain in 20 procedures (11%), and limb salvage in 34 procedures (19%). Follow up consisted of clinical evaluation, ankle-brachial index measurements and duplex scanning.
Results: the mean follow-up time was 29.3 months. The mean length of the endarterectomised SFAs was 31 cm (range, 17-45cm). The five year cumulative primary patency rate by means of life table analysis was 37.8+/-6.67% (SE). Percutaneous transluminal balloon angioplasty and surgical re-intervention were performed in twenty-nine and four patients respectively resulting in a primary assisted patency rate of 47.9+/-6.27%. Limb salvage was achieved in 30 of the 34 patients. Females had a statistically significant lower primary patency rate, i.e., 26 vs 45% (p -value=0.01).
Conclusions: the long term results of remote SFA endarterectomy show that it is a safe, effective and durable, minimally invasive procedure. It also leaves open all other options for conventional bypass procedures. The five-year primary patency rate is at least similar to prosthetic above-knee bypass surgery.

Background: This study aimed to examine the early clinical outcomes of AngioJet rheolytic thrombectomy (RT) in patients with acute bilateral iliofemoral deep vein thrombosis (IFDVT), with a specific focus on the incidence of post-thrombotic syndrome (PTS).
Methods: From March 2021 to August 2023, sixteen consecutive patients with acute bilateral IFDVT treated with AngioJet RT at our center were evaluated. Primary outcomes include patency of the target veins, development of PTS, recurrent DVT, and procedure related death.
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) .
Fully Covered Stent-TIPS for Advanced HCC Patients with Portal Vein Tumor Thrombus-Related Severe Symptomatic Portal Hypertension.

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.

Although venous stent placement is an established treatment for patients with deep vein thrombosis (DVT) and post-thrombotic syndrome (PTS), stent patency rate may be as low as 80% at 12 months. Treatment of stent occlusion requires the removal of a large amount of fresh or organized thrombus from stents with a diameter of 12-20 mm. The feasibility of large-bore rotational thrombectomy in combination with angioplasty to treat thrombosed venous iliofemoral or inferior vena cava stents has not been investigated yet.

Purpose: Angioplasty of lower extremity arteries with calcification may result in flow-limiting dissection requiring bail-out stenting with unfavorable long-term outcomes. Vessel preparation prior to angioplasty may improve immediate results of the angioplasty and long-term patency. This prospective study assessed the 12-month outcomes of patients who underwent novel vessel preparation catheter, the FLEX Vessel Prep™ System (FLEX VP), prior to drug-coated balloon angioplasty (DCB-PTA).
