BACKGROUND: Iliac vein injury associated with pelvic fracture due to blunt trauma is an uncommon and difficult diagnosis but a life-threatening condition which often requires an emergent management. Although open repair has been traditionally used as the treatment of choice in unstable patients, it is controversial, given the difficulty injured vessel exposure in patients with significant retroperitoneal hematoma as well as tamponade effect loss associated to laparotomy. We present a challenging case of iliac vein laceration successfully treated by placement of a self-expanding covered stent...

To investigate the mid- and long-term results of endovascular-based procedures for Cockett syndrome. The clinical data of 412 patients with Cockett syndrome treated between January 2003 and September 2017 were retrospectively analyzed. In these patients, 231 cases were acute left iliac femoral vein thrombosis (group A), and 181 cases were chronic venous insufficiency (group B), and different endovascular procedures and/or hybrid procedures were performed. In group A, the technique success rate was 100% (231/231); the left iliac vein in 5 patients showed no stenosis or occlusion, and the incidence of pathological changes in the left iliac vein was 97...

Pulmonary vein stenosis (PVS) is still a frustrating disease with extremely high mortality, especially in children with multiple severe PVS. Hybrid pulmonary vein stenting (HPVS) is a rescue treatment for recurrent and malignant PVS. The aim of this study is to share our successful experience with intraoperative HPVS for recurrent PVS after total anomalous pulmonary venous connection (TAPVC) repair in infant. Six patients were identified between 2013 and January 2018, who were diagnosed with recurrent PVS and underwent HPVS in the operating room...

Peripheral arterial occlusive disease is a chronic pathology affecting at least 8-12 million people in the USA, typically treated with a vein graft bypass or through the deployment of a stent in order to restore the physiological circulation. Failure of peripheral endovascular interventions occurs at the intersection of vascular biology, biomechanics, and clinical decision making. It is our hypothesis that the majority of endovascular treatment approaches share the same driving mechanisms and that a deep understanding of the adaptation process is pivotal in order to improve the current outcome of the procedure...

Introduction: Renal venous graft restenosis is an uncommon event usually associated with significant clinical impact. Its treatment by endovascular stenting is seldom reported in the literature. Report: Two cases of successful stenting for restenosis in aorto-renal venous grafts are described, detailing the technique and in one case reporting for the first time the use of a covered stent in this condition. Discussion: Technical success may be achieved with proper material selection for the patient's anatomy and with dilation at relatively high pressures...

BACKGROUND: May-Thurner syndrome (MTS) leads to an increased incidence of deep vein thrombosis (DVT). Early thrombus removal decreases the post-thrombotic morbidities. Our aim was to better elucidate the relationship between MTS and venous patency after Catheter-directed thrombolysis CTD. METHOD: The medical records of all patients who underwent CTD from January 2005 to December 2011 due to acute DVT were reviewed retrospectively. Patient characteristics and clinical variables were evaluated to determine association with vein patency...

Recently, new techniques and devices in transjugular intrahepatic portosystemic shunt (TIPS) placement have emerged that can improve upon the standard procedure. Ultrasound guidance during TIPS with intracardiac echocardiography (ICE), placement of controlled expansion (CX) stents, and portal vein recanalization (PVR) via transsplenic access are three techniques with new data supporting their implementation. ICE guidance can improve the technical success of difficult cases, decrease procedure time, and decrease complications such as capsular puncture, hemobilia, and hepatic artery injury...

May-Thurner syndrome (MTS) is a medical condition where the left iliac vein is compressed by the right iliac artery, which in turn predisposes patients to deep venous thrombosis (DVT). We present a case of a 67-year-old female who had pain and swelling of the left leg. Ultrasound of the deep veins of the leg revealed DVT of the distal external iliac vein. She was treated with catheter-directed thrombolysis and stent placement. Finally, she was discharged on long-term anticoagulation with warfarin. The purpose of presenting this case is to highlight the clinical presentation, diagnosis, and treatment of MTS...

BACKGROUND: Several large randomized controlled trials (RCTs) have proven the superiority of drug-eluting stents (DESs) over bare-metal stents (BMSs) for native coronary stenosis. However, RCTs comparing DESs with BMSs for SVG lesions have predominantly been small in size and have yielded conflicting results. Therefore, we conducted an updated comprehensive meta-analysis of RCTs comparing DESs versus BMSs for SVG interventions using the largest sample size to date. METHODS: Scientific databases and websites were searched to find RCTs...

BACKGROUND: Risk stratification after percutaneous coronary intervention (PCI) is mainly based on demographics and clinical presentation (stable coronary artery disease [CAD] vs. acute coronary syndromes [ACS]). We investigated the impact of PCI extent and complexity on 2-year clinical outcomes after successful implantation of drug-eluting stents (DES) and whether this effect is influenced by clinical presentation and/or high platelet reactivity (HPR) on clopidogrel. METHODS AND RESULTS: Patients from the prospective, multicenter Assessment of Dual Antiplatelet Therapy with Drug-Eluting Stents study were stratified according to PCI complexity, with complex PCI (C-PCI) defined as ≥3 stents implanted, bifurcation PCI with 2 stents, rotational atherectomy use for severely calcified lesions, or left main or saphenous vein graft (SVG) PCI...
