BACKGROUND: Subclavian and axillary artery injuries are uncommon. In addition to many open vascular repairs, endovascular techniques are used for definitive repair or vascular control of these anatomically challenging injuries. The aim of this study was to determine the relative roles of endovascular and open techniques in the management of subclavian and axillary artery injuries comparing hospital outcomes, and long-term limb viability. METHODS: A multicenter, retrospective review of patients with subclavian or axillary artery injuries from 1/1/2004-12/31/2014 was completed at 11 participating Western Trauma Association institutions...

The quality standards of the French Society of Vascular Medicine for the ultrasound assessment of lower limb arteries in vascular medicine practice are based on the principle that these examinations have to meet two requirements: technical know-how (knowledge of devices and methodologies); medical know-how (level of examination matching the indication and purpose of the examination, interpretation and critical analysis of results). OBJECTIVES OF THE QUALITY STANDARDS: To describe an optimal level of examination adjusted to the indication or clinical hypothesis; to establish harmonious practices, methodologies, terminologies, results description and report; to provide good practice reference points and to promote a high quality process...

Recently, the use of central venous catheters (CVC) as a vascular access in patients undergoing hemodialysis is significantly increased, mainly because of the aging of this population and the presence of several comorbidities. However, the implantation and the long stay of CVC are associated with many complications. Among them, central venous stenosis represents one of the most common problems that, if not properly diagnosed, could lead to vascular thrombosis and consequent vascular access malfunction. Here, we report a case of a 38-year-old patient, who underwent hemodialysis firstly by a CVC long-term into right jugular vein and then by a prosthetic fistula in the ipsilateral limb...

INTRODUCTION: The small diameter of temporary vascular shunts for vascular trauma management may restrict flow and result in ischemia or early thrombosis. We have previously reported a clinical experience with direct, open surgical reconstruction using expanded polytetrafluoroethylene (ePTFE) stent grafts to create a "sutureless" anastomosis as an alternative to standard temporary vascular shunts. We sought to characterize patency and flow characteristics of these grafts compared to standard shunts in a survival model of porcine vascular injury...

Background The endovascular approach has become a mainstay in the treatment of aortic aneurysms. While the transfemoral approach is most commonly used, it is often inaccessible due to a vascular pathology, such as occlusion, tortuosity or heavy calcifications. The transapical access provides an alternative approach. The goal of this study is to report the feasibility of the transapical approach for total endovascular repair of thoracic aortic aneurysms (TEVAR). Methods Three patients with thoracic aortic aneurysms with inaccessible femoral arteries underwent TEVAR via the transapical approach...

INTRODUCTION: Rupture of superior mesenteric artery aneurysm (SMAA) is a very rare and life-threatening condition, presenting with acute intraabdominal hemorrhage. CASE: The patient was hospitalized upon complaint of nonspecific severe abdominal pain. Diagnosis of SMAA was established by abdominal Doppler ultrasound that showed a pseudo-aneurysmal lesion with size of 76 × 47 mm at the superior mesenteric main branch. Endovascular stenting was not performed because of the wide neck in the segment of the jejunal branches from SMA and the risk of branch loss during treatment...

BACKGROUND: Endovascular aneurysm repair of aortoiliac or iliac aneurysms is often performed with stent graft coverage of the origin of the hypogastric artery (HA) to ensure adequate distal seal. It is considered common practice to perform adjunctive coiling of the HA to prevent a type II endoleak. Our objective was to question the necessity of pre-emptive coiling by comparing the outcomes of HA coverage with and without prior coil embolization. METHODS: Data from the Endurant Stent Graft Natural Selection Global Postmarket Registry (ENGAGE), which prospectively enrolled 1263 endovascular aneurysm repair patients between March 2009 and April 2011 from multiple centers worldwide, were used for this study...

BACKGROUND: Ultrasound-guided percutaneous endovascular treatment of arteriovenous fistula (AVF) or graft failure is an alternative to radiologically-guided angioplastic methods. Its main advantages are that it can be used with open or percutaneous access, using no contrast media and no radiation. The aim of this study was to analyze the results of ultrasound-guided endovascular treatment of arteriovenous access failure. MATERIAL AND METHODS: Preoperative ultrasound was used to determine the degree of stenosis and the size of balloon used in angioplasty...

Thoracic endovascular repair is considered the first-line treatment in complicated acute type B dissection. Central venous catheters provide valuable vascular access during endovascular treatments. However, central venous catheters are not without complications. Herein, we report a case of central venous catheter insertion into the false lumen of a complicated acute type B aortic dissection by direct aortic puncture. The tip of the central venous catheter was in the false lumen. The central venous catheter was left in place initially and was removed after graft stent deployment...

OBJECTIVE: The aim of this study was to evaluate the utility of the P4 stump stenting approach for treating portal vein (PV) complications in pediatric living donor liver transplantation (LDLT). BACKGROUND: PV complications cause significant morbidity and mortality in pediatric LDLT. Biliary atresia in the backdrop of pathological PV hypoplasia and sclerosis heightens the complexity of PV reconstruction. The authors developed a novel approach for intraoperative PV stenting via the graft segment 4 PV stump (P4 stump) to address this challenge...

Some studies consider the different physical properties of the stent graft when compared with the blood vessel on the basis of vascular lesions that may require further intervention. We present a case in which a patient developed an intramural hematoma at the distal landing of previous thoracic endovascular aortic repair (TEVAR) that required the relining with a flared prosthesis. During follow-up, we observed the appearance of more caudal hematoma. We decided to observe this lesion with close radiological controls...

Introduction In traditional locations, the standard Blalock-Taussig shunt presents numerous technical difficulties for percutaneous intervention. We changed our strategy to a central type shunt (Laks-type) with end-to-side pulmonary and side-to-side aortic anastomosis. The aim of this study was to determine whether this modified strategy would allow easier percutaneous manipulation in patients with small pulmonary arteries. Methods All children with a stretchable central vascular graft who required any form of percutaneous intervention were prospectively enrolled in the study...

PURPOSE: Pulse wave velocity (PWV), which measures vascular stiffness, is a powerful predictor of cardiovascular event. Treatment of aneurysms with endovascular prosthesis has been reported to increase PWV. The purpose of this study was to evaluate whether an endoskeleton stent graft design has less effect on PWV than the exoskeleton stent graft design. METHODS: Between July 2008 and September 2016, 74 patients underwent endovascular treatment of aortic arch aneurysm in our institution...

OBJECTIVE: Hostile proximal aortic neck (HN) challenges the suitability for standard endovascular aneurysm repair (EVAR) of patients at high risk for "open" repair. However, there has been little if any focus placed on the individual role of the "nonlength" HN features in EVAR outcomes. The aim of this study was to evaluate their individual and potentially predictive role in outcomes of EVAR under HN conditions. METHODS: Data of 156 consecutive EVAR patients with short (<15 mm) HN, treated with the Endurant device (Medtronic Cardiovascular, Santa Rosa, Calif) at three European academic vascular centers between 2007 and 2015, were collected and retrospectively analyzed...

Vascular complications are common after transcatheter aortic valve replacement (TAVR) and are associated with increased morbidity and mortality. Stent graft implantation enables percutaneous treatment of access site bleeding; however, the efficacy and durability and of this approach are unknown. We studied the immediate outcome of stent graft implantation for control of access site bleeding and the need for repeat vascular interventions after stenting, in a cohort of consecutive patients with severe symptomatic aortic stenosis who underwent transfemoral TAVR...
