OBJECTIVES: The management of patients with splenic artery aneurysms (SAAs) is variable since the natural history of these aneurysms is poorly delineated. The objective of this study was to review our experience with open repair, endovascular therapy, and observation of SAAs over a 14-year interval. METHODS: Between January 1, 1996 and December 31, 2009, 128 patients with SAAs were evaluated. Sixty-two patients underwent surgical repair (n = 13) or endovascular coil/glue ablation (n = 49), while 66 patients underwent serial observation...

OBJECTIVE: True splenic artery aneurysms (SAAs) are a rare but potentially fatal pathology. For many years, open repair (OPEN) and conservative management (CONS) were the treatments of choice, but throughout the last decade endovascular repair (EV) has become increasingly used. The purpose of the present study was to perform a systematic review and meta-analysis evaluating the outcomes of the three major treatment modalities (OPEN, EV, and CONS) for the management of SAAs. METHODS: A systematic review of all studies describing the outcomes of SAAs treated with OPEN, EV, or CONS was performed using seven large medical databases...

OBJECTIVE: Contrast-enhanced ultrasound (CEUS) imaging is a powerful noninvasive modality offering numerous potential diagnostic and therapeutic applications in vascular medicine. CEUS imaging uses microbubble contrast agents composed of an encapsulating shell surrounding a gaseous core. These microbubbles act as nearly perfect intravascular reflectors of ultrasound energy and may be used to enhance the overall contrast and quality of ultrasound images. The purpose of this narrative review is to survey the current literature regarding CEUS imaging and discuss its diagnostic and therapeutic roles in current vascular and selected nonvascular applications...

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: Therapeutic anticoagulation (AC) is used clinically for prolongation of infrainguinal bypass patency, but evidence for the efficacy of this practice is conflicting. The objective of our study was to determine the association of AC with bypass graft primary patency. METHODS: Clinical and comorbid data of patients undergoing infrainguinal bypass grafts to a below-knee target with at least 1 year of follow-up performed from 2003 to 2015 were obtained from the Society for Vascular Surgery Vascular Quality Initiative...

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...

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...
