This review analyzed the incidence, mechanisms, and risk factors of aortic-related reintervention after endovascular repair of chronic dissections. The systematic review identified 28 studies describing 1,249 patients at median 27 months follow-up (range, 10.3 to 64.4). There were six reinterventions, 0.7 ruptures, and 1.2 surgical conversions per 100 patient-years of follow-up. Stent-related reinterventions were more frequent than nonstent related (80.2% vs 19.8%). Distal false lumen perfusion was the most common complication (40...

OBJECTIVE: When a bypass fails, the options are lysis, redo bypass, or endovascular intervention. If lysis of the original bypass is not considered an option, which is better-redo bypass or attempts at endovascular recanalization of the native system? This retrospective study examined the outcomes of native superficial femoral artery (SFA) chronic total occlusion (CTO) recanalization compared with redo bypass after failed femoropopliteal bypass. METHODS: Patients presenting with a symptomatic failed femoropopliteal bypass that underwent attempted CTO endovascular (EV) recanalization of the native SFA or a redo femoropopliteal bypass (BP) from 2000 to 2015 were analyzed...

OBJECTIVE: The objective of this study was to evaluate the risk of recurrent ischaemic stroke in patients with ultrasound assessed symptomatic mild carotid artery stenosis (20-49% NASCET) treated solely with modern medical treatment. METHOD: This was a retrospective, observational register cohort study. Three groups of patients were recruited from a database of all carotid Doppler ultrasound examinations performed in the Gothenburg region between 2004 and 2009. Patients with symptomatic mild carotid artery stenosis (n = 162) were compared with patients with asymptomatic carotid artery stenosis (n = 301) of equal degree and a group of patients with surgically (CEA) treated symptomatic moderate or severe carotid artery stenosis (n = 220)...

OBJECTIVE: One complication of autogenous arteriovenous fistula (AVF) for hemodialysis is the formation of a venous aneurysm (VA). The treatment of massive aneurysmal AVF generally involves ligation or resection with the use of prosthetic interposition. Partial aneurysmectomy, with or without reduction venoplasty, has been suggested to treat such a complicated AVF to maintain an all-autogenous access. The purpose of this study was to describe these procedures and examine their outcomes...

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: Apixaban, an oral factor Xa inhibitor administered in fixed doses, may simplify the treatment of venous thromboembolism. METHODS: In this randomized, double-blind study, we compared apixaban (at a dose of 10 mg twice daily for 7 days, followed by 5 mg twice daily for 6 months) with conventional therapy (subcutaneous enoxaparin, followed by warfarin) in 5395 patients with acute venous thromboembolism. The primary efficacy outcome was recurrent symptomatic venous thromboembolism or death related to venous thromboembolism...
