DSCTA检查在腹主动脉瘤诊断及EVE术后随访中的临床价值
Clinical Value of Dual-source CT Angiography in Diagnosis and Following -up Postoperative Endovascular Stent-graft Exclusion of Abdominal Aortic Aneurysm
摘要
Abstract
Objective To investigate the value of dual-source CT angiography ( DSCTA ) in diagnosis and following-up postoperative endovascular stent-graft exclusion(EVE)of abdominal aortic aneurysm(AAA). Methods Eighty-six patients were diagnosed as AAA by dual-source CT angiography. Of these patients,16 patients with aneurysm body under renal artery underwent EVE were following-up observed by DSCTA. Imaging reconstruction that include multi-plane reconstruction( MPR) , maximum in-tensity projection(MIP)and volume rendering technique(VRT), and analysis were finished at workstation. Type, location, size and extension of AAA were focused. Besides, based on correlative measured parameters that satisfied requirement of EVE, AAA located under level of renal artery was classified. The outcomes and complications of 16 patients with AAA underwent EVE were focused. Results ①Eighty-six cases included 4 with aneurysm body located upper level of renal artery and 82 with aneurysm body located under level of renal artery. ②Based on requirement of EVE, 82 cases with aneurysms body located under level of re-nal artery were classified as 9 typeⅠ, 6 typeⅡA, 12 typeⅡB, 42 typeⅡC and 13 typeⅢ.③DSCTA images clearly displayed shape, locality and size of aneurysm, and anatomic relation between aneurysm body and adjacent main branches of aorta, and mu-ral thrombus in all patients. Furthermore, relative data of AAA could also be accurately measured on CTA images. ④The size of aneurysm body reduced to varying degrees or stabilized in all 16 cases underwent EVE, outer area of aneurysm body covered by stent-graft were almost filled with thrombus,and inner surface of stent-graft didn’t observed thrombus in every patient. Shape of stent-graft was normal in 12 cases and slightly abnormal in 4 cases. Stent endoleaking weren’t observed in 16 cases. Conclusion DSCTA examination with handy, effective and non-invasived advantages, is one of important imaging methods in diagnosis and mo-nitoring, preoperative evaluation,and following-up postoperative EVE of AAA.关键词
