Background—With recent advances in endovascular treatment, percutaneous endoluminal angioplasty has become particularly attractive for arterial lesions of Takayasu arteritis. However, data came from case reports or small series, and the long-term outcome has not been reported. The incidence of potential vascular complications after surgery or endovascular treatment is still to be determined.
Interventional management of recurrent deep vein thrombosis (DVT) may pose a more challenging scenario than the initial episode, with respect to both the technical approach and postprocedural management. These patients fall into two groups that have similarities as well as differences: those who have not undergone a previous interventional procedure and those with a history of endovenous intervention for DVT. Each group poses unique challenges to interventionists. In both groups, clinical and imaging assessment should be geared toward addressing the causes of recurrent DVT and determining the extent of venous thrombosis and/or obstruction.
Background—Recent technical advances have made endovascular treatment (EVT) an alternative first-line treatment for critical limb ischemia.
Background—Advanced chronic obstructive pulmonary disease causes a significant reduction in functional capacity because of dyspnea and fatigue, partially related to hypoxemia and compromised oxygen delivery. Percutaneous creation of an arteriovenous shunt may increase oxygen delivery and, hence, improve patients functional capacity.
Purpose: Catheter-directed thrombolysis (CDT) for proximal deep vein thrombosis (DVT) effectively enhances clot removal and recently has been shown to reduce the development of postthrombotic syndrome (PTS). This study was performed to identify potential markers for early and long-term efficacy of CDT, adverse events, and their interrelationship.
Since it was first described in 1990, subintimal angioplasty (SIA) has proven to be a valuable alternative for bypass surgery in patients with atheroocclusive disease of the superficial femoral artery (SFA).1 In this minimally invasive technique, a guidewire is intentionally placed between the intima and the media to create a new track along the vessel wall, bypassing the atherosclerotic occlusion.2 However, to our knowledge, the exact route of this subintimal track has never been confirmed with histopathology.
Purpose: Ultrasound-guided antegrade access during endovenous lower-extremity vein ablation may be problematic. This study describes fluoroscopic-guided retrograde access to the target veins in cases in which antegrade access proved unfeasible.
Background—Critical limb ischemia portends a risk of major amputation of 25% to 35% within 1 year of diagnosis. Preclinical studies provide evidence that intramuscular injection of autologous CD34+ cells improves limb perfusion and reduces amputation risk. In this randomized, double-blind, placebo-controlled pilot study, we evaluated the safety and efficacy of intramuscular injections of autologous CD34+ cells in subjects with moderate or high-risk critical limb ischemia, who were poor or noncandidates for surgical or percutaneous revascularization (ACT34-CLI).
Objectives: We examined the efficacy and durability of a new interwoven self-expanding nitinol stent system in the treatment of complex popliteal artery lesions in unselected patients.
The role of endovascular therapy is expanding in the treatment of acute limb ischemia (ALI). In addition to catheter-based thrombolysis, there are multiple devices which allow for clot disruption and aspiration. The Trellis catheter system provides mechanical agitation of thrombus coupled with chemical thrombolysis. We present two cases of native arterial occlusions in which the Trellis catheter was used for thrombolysis. Procedural tips and challenges associated with the use of this device in native vessels are discussed. © 2012 Wiley Periodicals, Inc.
Background—Peripheral arterial disease is a manifestation of systemic atherosclerosis and is predictive of future cardiovascular events. Clinical trial data have demonstrated that medical therapy can attenuate cardiovascular morbidity and mortality in patients with peripheral arterial disease. The utilization and impact of recommended medical therapy in a contemporary population of patients who undergo percutaneous interventions for lifestyle-limiting peripheral arterial disease is unknown.
Purpose: To evaluate early patency rate of the heparin-bonded stent grafts in atherosclerotic long femoropopliteal occlusive disease, and to identify factors that affect outcome.

PURPOSE: We aimed to describe the long-term outcome of endovascular treatment of iliofemoral deep vein thrombosis in the postpartum period. Diagn Interv Radiol 2012; 18:587–593 Diagn Interv Radiol DOI 10.4261/1305-3825.DIR.5808-12.1 Copyright © Turkish Society of Radiology 2012
Purpose: This study was designed to assess aorto-iliac morphological characteristics in relation to reintervention and all-cause long-term mortality in patients undergoing standard EVAR for infrarenal AAA.

Purpose: Abdominal aortic aneurysm (AAA) accompanied by common iliac artery (CIA) aneurysms requires a more demanding procedure owing to the difficulties in obtaining an adequate distal landing zone for the stent-graft limb(s), a potential site of endoleak. The “sandwich technique” is a procedure to increase EVAR feasibility in the setting of adverse or challenging CIA anatomy. Its main advantages include no restrictions in terms of CIA diameter or length or internal iliac artery (IIA) diameter, no need to wait for a specific stent-graft. Our purpose is to describe our single-center experience and one year follow-up results of this new procedure.
