主动脉瘤的血管内支架治疗

作者对１例胸腹主动脉瘤（假性）伴后纵隔和腹膜后血肿患者作了密集网格式镍钛合金内支架治疗。经股动脉入路，用１２Ｆ导管将直径２０ｍｍ、长９０ｍｍ内支架跨靶病灶放置，另一直径２４ｍｍ、长５０ｍｍ内支架则用于加固前者。术后即刻造影示动脉瘤被部分隔离；２周后ＣＴ和造影随访显示：瘤腔被完全隔离，主动脉狭窄和受压移位消失，所有分支血管完全畅通，支架无移位。临床随访至今８周未出现腹痛复发，围手术期亦未发生严重并发

Application of Self-expandable Nitinol Mesh Stent in the Treatment of Aortic Aneurysm

This article reported a case,female,age 44 years suffering from thoracicoab- dominal pseudoaneurysm surrounded by a huge hematoma in the postmediastinal and retroperitoneal space,and treated with two self-made self-expandable nitinol mesh stents. The stents were delivered through 12F catheter sheath via femoral artery approach.One stent (20mm in diameter and 90mm in length) was transluminally implanted across target lesion and the other one (24 mm in diameter and 50mm in length)was used for fixation. Immediately after the procedure, the aneurysm was partially isolated as seen on the aortogram. Follow -up CT scan and aortography two weeks later revealed that the aneurvsm was completely isolated,and the aorta recovered to its normal size and shape with fully patent branches. There were no abdominal pain and no serious complications.Our preliminal experi- ence suggestes that treatment of aortic pseudoaneurysm with nitinol mesh stent seem to be feasible- and safe,but further investigation is necessary.
