BACKGROUND: Cilostazol improves clinical endovascular therapy outcomes for femoropopliteal (FP) lesions in patients with symptomatic peripheral arterial disease, but whether it also has clinical benefits for patients after drug-eluting stent implantation remains unclear. METHODS: This study is a subanalysis of the ZilvEr PTX for tHe Femoral ArterY and Proximal Popliteal ArteRy (ZEPHYR) study, a prospective multicenter study investigating FP lesions treated with the Zilver (Cook Medical, Bloomington, Ind) paclitaxel-eluting stent...

Purpose Percutaneous remote access for endovascular aortic repair is an advantageous alternative to open access. Previous surgery in the femoral region and the presence of synthetic vascular grafts in the femoral/iliac arteries represent major limitations to percutaneous remote access. The aim of this study was to evaluate an original technique used for enabling percutaneous remote access for thoracic or abdominal endovascular aortic repair in patients with scar tissue and/or a vascular graft in the groin. Methods Twenty-five consecutive patients with a thoracic (11/25; 44%) or an aortic aneurysm (14/25; 66%) and with a synthetic vascular graft in the groin (16/25; 64%) or a redo groin access (9/25; 36%) were managed through the percutaneous remote access...

Transcaval access has been used successfully for over 200 transcatheter aortic valve replacements, large-bore percutaneous left ventricular assist devices, and thoracic endovascular aortic aneurysm repairs. This review teaches how to plan transcaval access and closure based on computed tomography. The main planning goals are to: 1) identify calcium-free crossing targets in the abdominal aorta along with optimal fluoroscopic projection angles and level with respect to lumbar vertebrae; 2) identify obstacles such as interposed bowel or pedunculated aortic atheroma; 3) plan covered stent bailout; and 4) identify jeopardized vascular branches such as renal arteries that might be obstructed by bailout covered stents if employed...

OBJECTIVE: Endovascular interventions of the common femoral (CFA) and deep (DFA) femoral arteries are becoming more common. However, there is very little published data for guidance. Our objective was to analyze practice patterns and outcomes from these interventions. METHODS: The Vascular Quality Initiative (2010-2015) was queried for all endovascular interventions of the CFA and DFA. Cases that were emergent or for acute limb ischemia were excluded. Those with isolated CFA with or without DFA treatment were analyzed...

BACKGROUND: Gender and age are non-modifiable factors influencing clinical outcomes in acute coronary syndromes (ACS). There is evidence that coronary artery disease pathophysiology varies in women. We therefore evaluated the effect of age and gender on clinical outcomes in patients with ACS undergoing percutaneous coronary interventions (PCI). METHODS: Among 3178 (25% female) consecutive ACS patients who underwent PCI at Liverpool Hospital, Sydney from 2003 to 2010, using femoral access in 98% of cases, we determined late events including mortality, myocardial infarction and bleeding according to Bleeding Academic Research Consortium (BARC) criteria...

Endovascular repair has revolutionised the emergency treatment of thoracic aortic disease. We report our 10 year experience using this treatment in emergency cases. A prospectively maintained vascular database was analysed. Patients' medical records and CT images stored on the hospital PACS system were also reviewed. Statistical analysis was done using IBM SPSS V21. There were a total of 59 thoracic aortic stenting procedures of which 33 (60% males with a mean age of 58 yrs) were performed for emergency thoracic pathologies: traumatic transection (n = 10), ruptured aneurysm (n = 6), non-traumatic dissection (n = 8) and penetrating aortic ulcer (n = 9)...

A 79-year-old man underwent bifurcated graft replacement for abdominal aortic aneurysm, but the graft was totally occluded owing to an acute type B aortic dissection. We could not have access to the root for performing endovascular stenting for dissecting aneurysm. Furthermore, it was difficult to remove the aneurysm via a left thoracotomy because it was impossible to perfuse the lower body with blood from the femoral artery and also a left axillary arterial cannulation was unusable. Herein, we report a patient who was successfully treated with open surgical aortic stenting for an enlarged ulcer-like projection complicated by a type B aortic dissection...

Tracheoinnominate artery fistula is a rare, fatal complication of tracheostomy, and prompt diagnosis and management are imperative. We report the case of tracheoinnominate artery fistula after tracheostomy in a 14-year-old boy with a history of severe periventricular leukomalacia, hydrocephalus, cerebral palsy, and epilepsy. The tracheoinnominate artery fistula was successfully treated with a stent graft insertion via the right common femoral artery. Endovascular repair of the tracheoinnominate artery fistula via stent grafting is a safe, effective, and minimally invasive treatment for patients in poor clinical conditions and is an alternative to traditional open surgical treatment...

The objective of this work was to develop a system for three-dimensional (3D) reconstruction of the femoropopliteal artery from two angiographic views and to quantify the in vivo 3D deformations in 18 patients before balloon angioplasty and after primary stent implantation. The procedure had an insignificant effect on the bending behavior of the artery, as the average mean curvature change within the lesion remained constant before (0.04 cm(-1) ± 0.03) and after stent implantation (0.03 cm(-1) ± 0.04). A significant effect of stent implantation was measured in terms of a decrease in arterial shortening during leg flexion...

False aneurysms are formed as a result of bleeding causing a hematoma to compress the surrounding tissue. The majority of false aneurysms presenting to the vascular surgeon are caused by iatrogenic injury to an artery. Although anastomotic failure occurs, a much higher number is caused by bleeding from puncture sites after percutaeous intervention. Anticoagulative medication, low patelet counts and severely calcified vessels increase the risk of forming a false aneurysm. Experienced specialists may make the diagnosis from physical examination, but ultrasound imaging is almost always needed in order to decide for a treatment strategy...

: Restenosis after angioplasty is a serious clinical problem that can result in re-occlusion of the coronary artery. Although current drug-eluting stents have proved to be more effective in reducing restenosis, they have drawbacks of inhibiting reendothelialization to promote thrombosis. New treatment options are in urgent need. We have shown that netrin-1, an axon-guiding protein, promotes angiogenesis and cardioprotection via production of nitric oxide (NO). The present study examined whether and how netrin-1 attenuates neointimal formation in a femoral wire injury model...

AIMS: Limited data exist on the treatment and outcomes of patients with chronic total occlusions due to in-stent restenosis (CTO-ISR). We sought to evaluate results and clinical outcomes in percutaneous interventions over CTO-ISR. METHODS AND RESULTS: Registry in 16 centers involving consecutive patients undergoing attempt of percutaneous intervention over CTO-ISR. A total of 233 patients were included, 192 (82.4%) with successful acute result. Success rate was significantly lower in patients with: lesion in circumflex artery, ostial lesion, J score > 3 and no femoral access...

BACKGROUND: Transcaval access may enable fully percutaneous transcatheter aortic valve replacement (TAVR) without the hazards and discomfort of transthoracic (transapical or transaortic) access. OBJECTIVES: We performed a prospective, independently-adjudicated, multi-center, single-arm Investigational Device Exemption trial of transcaval access for TAVR in patients ineligible for femoral artery access and high or prohibitive risk of complications from transthoracic access...

BACKGROUND: Venous drainage from the leg is poorly understood, and it is difficult to quantify it hemodynamically. Attempts have been made using duplex ultrasound scanning and venous occlusion air plethysmography (APG). However, they have limited value in day-to-day clinical practice. This is because venous drainage measurements have never been validated successfully against increasing obstruction pressures. The hypothesis is that the novel gravitational venous drainage index (VDI) in milliliters/second is reduced in response to increasing venous obstruction, and the aim was to quantify this, using stepwise inflations of a thigh cuff...

OBJECTIVE: Historically, edge stenosis and late thrombosis limited the effectiveness of adjunctive endovascular brachytherapy (EVBT) for in-stent restenosis (ISR) after percutaneous transluminal angioplasty (PTA) and stenting. We evaluated an updated protocol of PTA and EVBT for ISR among patients with lower extremity occlusive disease. METHODS: This is a retrospective, single-center review of patients treated with PTA and EVBT for ISR in the iliac and femoropopliteal segments between 2004 and 2012...
