BACKGROUND: The impact of vascular injuries on patient mortality has not been well evaluated in multi-trauma patients. This study seeks to determine (1) whether the presence of vascular trauma negatively affects outcome compared with nonvascular trauma (NVT) and (2) the utility of existing severity scoring systems in predicting mortality among vascular trauma (VT) patients. METHODS: A retrospective review of our trauma database from January 2005 to December 2007 was conducted...

A metaanalysis of articles concerning the surgical management of acute traumatic rupture of the descending thoracic aorta published in the English-language literature between 1972 and July 1992 was performed. The overall mortality of 1,742 patients who arrived at the hospital alive was 32.0%, one-third died before surgical repair was started. Paraplegia was noted preoperatively in 2.6% of these hospitalized patients, and paraplegia complicated the surgical repair in 9.9% of 1,492 patients who reached the operating room in a relatively stable condition...

BACKGROUND: Direct oral anticoagulants (DOACs) are used as an alternative for traditional antithrombotic therapy. However, the safety profile of DOACs in patients with renal failure (RF) has not been determined. METHODS: A systematic review was performed assessing the reported safety of DOACs compared with vitamin K antagonists (VKAs) in patients with RF and estimated creatinine clearance (eCrCL) < 50 mL/min and eCrCL 50 to 80 mL/min. MEDLINE, EMBASE, Cochrane, and the Clinical Trials Registry (ClinicalTrials...

OBJECTIVE: Thoracic endovascular aortic repair (TEVAR) has become a widely established treatment for a variety of thoracic aortic pathologic diseases despite limited long-term data to support its use. We compared the long-term outcomes of TEVAR with the 3 commercially available stents grafts for thoracic aortic aneurysms to results in control subjects undergoing open surgery. METHODS: Demographic, clinical radiographic parameters were collected prospectively on patients enrolled in trials assessing the Gore TAG (55), Medtronic Talent (36) and Cook TX2 (15) devices...

BACKGROUND: Thoracic endovascular aortic repair (TEVAR) is widely used for treatment of traumatic aortic injury (TAI). Stent graft coverage of the left subclavian artery (LSA) may be required in up to 40% of patients. We evaluated the long-term effects of intentional LSA coverage (LSAC) on symptoms and return to normal activity in TAI patients compared with a similarly treated group whose LSA was uncovered (LSAU). METHODS: Patients were identified from a prospective institutional trauma registry between September 2005 and July 2012...

The aim of this study is to give an overview of current knowledge regarding abdominal aortic aneurysm (AAA) growth after endovascular aortic aneurysm repair (EVAR) that could potentially lead to aortic rupture. A search on Pubmed was performed. A total of 705 articles were found after initial search, of which 49 were included in the final selection. Reports on the incidence of aneurysm enlargement after EVAR vary between 0.2% and 41%. Continuous growth could lead to rupture of the aneurysm sac. There are several supposed risk factors for growth after EVAR...

OBJECTIVE: The predominant mode of bare nitinol stent failure is diffuse in-stent restenosis, and failure rates correlate to the length and complexity of the treated lesion. Addition of an expanded polytetrafluoroethylene lining to a nitinol stent frame, as found in the VIABAHN endoprosthesis, mitigates the ingrowth of intimal hyperplasia. We compared the long-term outcomes of complex superficial femoral artery disease intervention using the VIABAHN endoprosthesis to those obtained with bare nitinol stent implantation...
