Complete stent graft relining of the hemodialysis access circuit for access salvage.

Background: Stent grafts (SGs) are widely used in hemodialysis access procedures to maintain function and patency of the access circuit. There are no reports to date describing complete relining of the access circuit with SGs for extreme access salvage.

Objective: To report outcomes and experience with complete SG relining of the hemodialysis access circuit.

Stent Grafts Across the Elbow Joint for Access Salvage.

Purpose: Covered stent grafts (SGs) are currently being used in a wide variety of situations to maintain function and patency of hemodialysis access circuits. Stent grafts are rarely placed across the elbow joint (EJ), however, due to fear of stent fracture. This study reports on the experience and patency rates with SGs across the EJ.

Pave and Pop: A novel addition to the endovascular treatment of hemodialysis access aneurysms.

Background: Hemodialysis access sites can be complicated by both true and false aneurysms with significant potential morbidity. Aneurysms have traditionally been treated by a variety of surgical methods. Less commonly, endovascular treatment with stent graft placement has been used as an alternative to open surgery.

Patency and Durability of Stent Grafts Placed in the Dialysis Circuit Cannulation Zone.

Purpose: To investigate the safety, durability, and patency rates of stent grafts (SGs) placed in the cannulation zone of hemodialysis access circuits.

Materials And Methods: From April 2020 to April 2023, all procedures with SGs placed in the cannulation zone were retrospectively analyzed. A total of 40 patients (25 men and 15 women) with SGs placed in the cannulation zone were included in the study.

Early experience with the Abre venous stent for central venous stenoses and occlusions in hemodialysis patients.

Background: Hemodialysis patients are prone to stenoses and occlusions throughout the access circuit. Central venous stenoses or occlusions (CVO) can be particularly challenging. There are many different types of balloons and stents available for treatment, including a new generation of dedicated venous stents (VS).

In-thrombus thrombin secretion: a new diagnostic marker of atrial fibrillation in cryptogenic stroke.

Background: Endovascularly retrieved clots are a potential resource for diagnosing stroke etiology, which may influence secondary prevention treatment. In this study we measured thrombin activity eluted by serially washing clots.

Methods: Clots were retrieved from 68 patients with acute ischemic stroke, freshly frozen and classified by standard criteria into proven atrial fibrillation (AF, 18 patients), atherosclerotic origin (AS, 15 patients), cryptogenic stroke (Cr, 17 patients) and other known causes (18 patients).

Inguinal lymphadenopathy as a predicting factor for ipsilateral primary limb amputation after a successful endovascular treatment.

Purpose: To assess the correlation between inguinal lymph node characteristics and ipsilateral limb amputation rates in patients with ischemic foot ulcers after a successful endovascular treatment.

Method: A retrospective review of patients who were endovascularly treated for ischemic foot ulcers between January 2015 and May 2017. Technical success was defined as arterial recanalization with stenosis less than 30 % and ankle brachial index improvement by > 0.

Primary Retrograde Dorsalis Pedis Artery Single Access for Revascularization of Chronic Total Occlusion in Patients with Critical Limb Ischemia.

Purpose: To evaluate the dorsalis pedis artery (DPA) approach as a single access site for revascularization in patients with critical limb ischemia (CLI) when the femoral approach is hostile or unavailable.

Materials And Methods: A retrospective review of patients who underwent iliac and femoropopliteal ipsilateral revascularization via a single access site from the DPA between January 2017 and February 2018 was performed. Fifteen limbs in 15 patients (10 men and 5 women; average age 72 y; range, 49-96 y) with CLI and unavailable femoral access were included.

The Aortic Bifurcation Angle as a Factor in Application of the Outback for Femoropopliteal Lesions in Ipsilateral Versus Contralateral Approaches.

Purpose: To assess the technical success of the Outback reentry device in contralateral versus ipsilateral approaches for femoropopliteal arterial occlusion.

Materials And Methods: A retrospective review of patients treated for critical limb ischemia (CLI) using the Outback between January 2013 and July 2016 was performed. Age, gender, length and site of the occlusion, approach site, aortic bifurcation angle, and reentry site were recorded.
