OBJECTIVE: There is no international consensus regarding the optimum management of infected aortae (mycotic aneurysms, infected aortic grafts). Neoaortoiliac reconstruction has advantages over extra anatomical bypass grafting; however use of autologous vein is associated with venous hypertension and compartment syndrome, alternatively cadaveric homografts are associated with high rates of perianastomotic haemorrhage, limb occlusion and pseudoaneurysm. Arterial repair using xenoprosthetic patches is associated with lower infection rates compared to the use of prosthetic material...

BACKGROUND: The Society of Vascular Surgery (SVS) guidelines currently suggest thoracic endovascular aortic repair (TEVAR) for grade II-IV and non-operative management (NOM) for grade I blunt traumatic aortic injury (BTAI). However, there is increasing evidence that grade II may also be observed safely. The purpose of this study was to compare the outcome of TEVAR and NOM for grade I-IV BTAI and determine if grade II can be safely observed with NOM. METHODS: The records of patients with BTAI from 2004 to 2015 at a Level I trauma center were retrospectively reviewed...

BACKGROUND: Acute kidney injury (AKI) has been found to be associated with short- and long-term mortality and morbidity in various clinical settings. However, it is unknown whether AKI after endovascular repair of abdominal aortic aneurysms (EVAR) is associated with postoperative mortality. METHODS: This observational study analyzed patients who underwent EVAR. The primary outcome was all-cause mortality. The outcomes of patients with and without postoperative AKI were compared using the Kaplan-Meier method and log-rank test...

BACKGROUND: Spinal aneurysms are rare among spinal arteriovenous malformations (SAVMs). There are few reports of endovascular management of spinal aneurysms associated with SAVM. OBJECTIVE: To present endovascular management of aneurysms associated with SAVM. METHODS: Of 91 patients with SAVMs,eight (9%) presented with aneurysms. Of these, three were male and five were female with a median age of 18 years (range 11-38). We evaluated the presenting pattern, lesion level, type of the target aneurysm related to the presenting pattern and AVM nidus, and the result obtained after embolization or open surgery...

BACKGROUND: Oral anticoagulants (OACs) reduce stroke risks with nonvalvular atrial fibrillation (AF); however, they are underused because of absolute or relative contraindications due to real or perceived risk of bleeding. Although left atrial appendage closure is increasingly performed in OAC-ineligible patients, this has not been studied in a randomized controlled trial. STUDY OBJECTIVES: The ASAP-TOO study is designed to establish the safety and effectiveness of the Watchman left atrial appendage closure device in patients with nonvalvular AF who are deemed ineligible for OAC...

BACKGROUND: Hemodialysis arteriovenous fistulas (AVFs) are suboptimally used primarily due to problems with maturation, early thrombosis, and patient nonacceptance. An endovascular approach to fistula creation without open surgery offers another hemodialysis vascular access option. STUDY DESIGN: Prospective, single-arm, multicenter study (Novel Endovascular Access Trial [NEAT]). SETTINGS & PARTICIPANTS: Consecutive adult non-dialysis-dependent and dialysis-dependent patients referred for vascular access creation at 9 centers in Canada, Australia, and New Zealand...

Endovascular redo aortic operations are a challenging undertaking. Techniques for treatment date almost as far back as the original open repair itself. Risk factors for failure following aortic repair include larger AAA necks, severe neck angulation, as well as clinical variables such as age, family history, obesity and chronic obstructive pulmonary disease. The armamentarium of endovascular treatments is vast and increasing. Aside from provisional embolization of endoleaks or deferment to open repair conversion, attention should be directed toward obtaining adequate proximal and distal sealing...

Aortic dissection is a life threatening condition. Hybrid repair has been described for the treatment of complex aortic pathology such as thoracoabdominal aortic aneurysms (TAAA) and type A and B dissections, although open and total endovascular repair are also possible. Open surgery is still associated with substantial perioperative morbi-mortality rates, thus less invasive techniques such as endovascular repair and hybrid procedures can achieve good results in centers with experience. We present the case of a patient with a chronic type B dissection and TAAA degeneration that was treated in a single stage hybrid procedure with antegrade supra-aortic and renovisceral debranching from the ascending aorta and TEVAR...

Conventional open surgery still remains as the gold standard of care for aortic arch and thoracoabdominal pathology. In centers of excellence, open repair of the arch has been performed with 5% immediate mortality and a low rate of complications; however overall mortality rates are around 15%, being up to 40% of all patients rejected for treatment due to their age or comorbidities. For thoracoabdominal aortic pathology, data reported from centers of excellence show immediate mortality rates from 5% to 19%, spinal cord ischemia from 2...

Visceral arteries aneurysms (VAA) are an increasingly interesting clinical entity due to their challenging diagnosis and treatment options. The more prevalent use and accuracy of enhanced imaging techniques such as ultrasonography and computed tomography have increased the frequency of diagnosis of aneurysmal degeneration of the visceral arteries. Despite there is no statistically significant difference in terms of overall mortality and post-operative complications between endovascular therapy and open repair, interventional strategies present a significantly lower length of stay and less invasiveness and should be preferred in elderly patients, or in case of co-morbidity and poor candidates for surgery...

INTRODUCTION: Mycotic aneurysms are a serious complication of infective endocarditis with increased risk of intracranial hemorrhage. Patients undergoing open heart surgery for valve repair or replacement are exposed to anticoagulants, increasing the risk of aneurysm bleeding. These patients may require endovascular or surgical aneurysm treatment prior to heart surgery, but data on this approach are scarce. METHODS: Retrospective review of consecutive patients with infectious endocarditis and mycotic aneurysms treated endovascularly with Trufill n-butyl cyanoacrylate (n-BCA) at the Cleveland Clinic between January 2013 and December 2015...
