Long-term results of microcoil embolization for XXXX : how common is rebleeding?

@entity1 @entity1347 @entity694 @entity548
OBJECTIVE: To determine the long-term results of @entity1 undergoing transcatheter coil embolization for the treatment of acute @entity548 . METHODS: @entity1 undergoing angiography for suspected @entity694 between January 2002 and December 2012 were reviewed (average age, 60   years; 38.4% male). Baseline, procedural and outcome parameters were recorded following the Society of Interventional Radiology guidelines. Primary outcome measures included early (<30   days) and delayed (>30   days) rebleeding events and adverse procedure-related complication. Average follow-up time was 996   days (median, 232   days; range, 30-3663   days). RESULTS: One or multiple sites of @entity548 were identified in 40 cases. Coil embolization was performed in 39 @entity1 , 26 (66.7%, 26/39) of whom were treated successfully without technical/clinical failure (n   =   12) or loss to follow-up (n   =   1). Three @entity1 (11.5%, 3/26) rebled in the early period within 30 days; one @entity1 went on to hemicolectomy. Four @entity1 (15.3%, 4/26) experienced delayed rebleeding after 30   days; two of whom also underwent hemicolectomy. No major complication occurred. One minor complication of @entity1347 was seen in the clinical failure group. One case of asymptomatic ischaemia was identified on a @entity1 undergoing pre-operative colonoscopy for elective bowel resection. No instances of ischaemic stricture were seen. All-cause mortality of successfully treated and all @entity1 at 1   year was 31% (8/26) and 30% (12/40), respectively. CONCLUSION: Transcatheter coil embolization is a durable treatment option with a technical and clinical success rate of 67% in the setting of acute @entity548 . A modest level of rebleeding was seen among successfully treated @entity1 in both the early and delayed periods; in the majority of @entity1 , embolization proved to be definitive therapy. ADVANCES IN KNOWLEDGE: Transcatheter coil embolization is a durable and potentially definitive therapy in the management of acute @entity548 .
