Purpose: To evaluate the angiographic and clinical effects of percutaneous transluminal angioplasty (PTA) of distal ostial collateral stenoses in patients with claudication and long-segment occlusion of the superficial femoral artery (SFA).
Methods: In ten patients (9 men, 1 woman) with stable intermittent claudication due to chronic long-segment occlusion of the SFA a high-grade stenosis of the distal collateral ostium of the deep femoral artery to the popliteal artery were dilated. PTA was performed using popliteal artery access. Claudication distances on the treadmill and ankle-brachial pressure indices (ABI) at rest were analyzed before, 1 week, and 14 weeks after PTA.
Results: Initial technical success was obtained in all patients. There were no significant periprocedural local complications. The initial mean claudication distance on the treadmill increased significantly from 107 +/- 65 m to 306 +/- 209 m (p < 0.01), the maximal claudication distance from 203 +/- 128 m to 392 +/- 167 m (p < 0.01). The mean ABI changed slightly but significantly (0.61 +/- 0.08 vs. 0.64 +/- 0.07; p < 0.05). Early follow-up after 14 weeks revealed no clinical deterioration.
Conclusion: This new technique is considered helpful in patients with well-defined claudication and long-segment occlusion of the SFA.

We present a case of an 86-year-old female with chronic mesenteric ischemia secondary to long-segment flush occlusion of the superior mesenteric artery and near-total occlusion of the celiac artery. The superior mesenteric artery was unable to be revascularized by conventional antegrade approaches. Successful transcollateral crossing of the occluded superior mesenteric artery and body-flossing, followed by antegrade balloon angioplasty, shockwave lithotripsy, and stent implantation were performed.

Interventional therapies to relieve chronic deep vein thrombosis (DVT) fail through inability to penetrate, cross, and remove the occlusion. Development of suitable tools requires fundamental understanding of chronic DVT mechanical properties and a reliable model for testing. Female farm swine underwent a novel, endovenous generation of long-segment unilateral iliac vein thrombosis.

Purpose: Endovascular therapy (EVT) has emerged as a primary approach for managing femoropopliteal artery (FPA) lesions, leveraging drug-eluting stents (DESs), and drug-coated balloons (DCBs), to enhance clinical outcomes. Although a full DES coverage strategy is effective in treating complex lesions, concerns over long-term complications prompt the exploration of alternative strategies. The aim of this study was to investigate clinical result of combination therapy of DES with DCB and compare them with full DES implantation.

Systemic venous baffle obstruction is a long-term complication that can arise from the Mustard operation. We outline a novel percutaneous approach to a long segment, complete occlusion of a Mustard baffle using electrosurgical recanalization and stenting.

Introduction: Establishing optimal vascular access sites is important for the procedural success of endovascular treatment (EVT) and the patient's comfort afterwards. Among the variety of vascular access sites, the transankle intervention (TAI) has been used more recently; however, there have been no reports of complex lower extremity arterial disease lesions treated with the TAI manoeuvre.
Report: An 82 year old man with chronic limb threatening ischaemia in both lower extremities underwent EVT for bilateral long segment occlusion from the iliac arteries to the superficial femoral artery (SFA).
