OBJECTIVETo investigate the post-operative complications of aortic endovascular grafting exclusion (EVGE) and its reasons and treatments.

METHODSClinical data of 82 cases received aortic endovascular grafting exclusion from January 2002 to October 2008 were retrospectively analyzed. Seventy-one cases were male and 11 cases were female with the age of 33 to 78 years and the average age of 49.2 years. There were 66 cases of thoracic aortic dissecting aneurysms and 16 cases of abdominal aortic aneurysm. The effect, post-operational complications and its treatment were investigated.

RESULTSThere were 90.1% patients had been followed up with the time of 3 to 78 months with technical success of 90.3%, clinical success of 94.1%, peri-operational mortality of 2.4%, total mortality of 6.1% and mortality associated with EVGE of 2.4%. Twenty-one cases underwent complications including type I endoleak (13 cases), abdominal aortoduodenal fistula (1 case), narrow true lumen (2 cases), reverse Stanford A dissection (2 cases), post EVGE syndrome (12 cases), delayed healing of inguinal incision (5 cases), constipation (3 cases), cerebral infarction (1 case). No paraplegia, left subclavian artery ischemia, contrast media associated nephrosis, ischemic colitis, ischemic neurologic injury, and artery embolism occurred. Post operation 4 cases had the second intervention including 2 type I endoleak and 2 narrow true lumen.

CONCLUSIONSThe technique-related complications still hinder the long-term effect of EVGE. It needs to be further investigated on technique improvement and treatment standardization.
