Objective To summarize the clinical experience of capture technology in the large diameter of abdominal aortic aneurysm in endovascular repair of abdominal aortic aneurysm(EVAR). Methods We retrospectively analyzed clinical data of 6 patients with abdominal aortic aneurysm (maximum diameter of 6.0 cm or bigger) in our hospital between July 2013 and May 2014.There were 3 males and 3 females at age of 76.2(73–81) years. Two patients of ruptured abdominal aortic aneurysm, in EVAR, established orbit using the capture technology successfully. Results The capture technology made the thread through the proximal tumor neck smoothly, successful repaired. One patient of rupture of abdominal aortic aneurysm was dead after 10 hours. One patient was lost to follow-up. Four patients were followed up for 3 to 11 months. The four patients had not occurred bracket displacement, internal leakage, thrombosis, or other serious complications. Conclusion For the patients with larger abdominal aortic aneurysm, capture technology may be used to the thread through the proximal tumor neck, to build a convey or track easily, to shorten the operation time, to improve the success rate of surgery.
目的 探討多層螺旋CT血管造影（CTA）在主動脈夾層中的診斷價值及臨床應用。 方法 回顧性分析2010年2月－2011年4月35例行CTA檢查的主動脈夾層患者，所有患者原始數據在圖像后處理工作站采用多平面重建、容積再重建、最大密度投影等方法進行主動脈成像。由2名有經驗的放射科副主任醫師進行診斷。 結果 35例均可明確顯示主動脈夾層的真假腔、內膜片及破裂口部位。Ⅰ型12例，Ⅱ型3例，Ⅲ型20例；累及左鎖骨下動脈5例，左頸總動脈2例，無名動脈2例，腹腔干3例，腸系膜上動脈4例，左腎動脈3例，右腎動脈2例，右髂總動脈受累6例，左髂總動脈受累8例，其中雙側髂總動脈均受累4例；合并動脈瘤3例；壁內血腫4例；所有患者均顯示了單一或多發破口。 結論 CTA及圖像后處理技術能快速、準確地診斷主動脈夾層，為臨床治療方案選擇提供重要的影像學依據。
