Results The success rate of endovascular graft exclusion was 88.9% (8/9).Nine mainly covered stents and 1 short covered stent were implanted.One patient died of aortic rupture after intraoperative implantation??2 patients had partial closure of the left subclavian artery??and 1 patient had a small amount of residual leakage.One patient died of aortic rupture 36 hours after the operation??and 7 patients discharged.The average time of postoperative follow-up was (69±29)months.One patient appeared to have cerebral hemorrhage with ineffectiveness of the right side of the body and 1 patient died without known causes.The other 5 patients were stable with good postoperative recovery.Conclusion It is both long-term and short-term effective with high success rates and few complications to treat thoracic aortic rupture incompletely merged with left hemothorax or near rupture in dilated aorta diseases by endovascular graft exclusion combined with chest tube drainage.     

Emergency stent graft deployment for acute aortic rupture following primary stenting for aortic coarctation.

We present a case of endovascular stenting for aortic recoarctation complicated by acute aortic rupture, which was successfully treated by emergency stent graft deployment. This case illustrates the potential serious complication that can occur during aortic stent dilatation and how the prompt deployment of a stent graft helped to change the clinical outcome of this life-threatening situation.     

Percutaneous Management of RetroFlex 3 Balloon Rupture and Separation of the Edwards Sapien Delivery System

We report the case of an 85-year-old woman with severe aortic stenosis who underwent transcatheter aortic valve replacement with use of the Edwards Sapien^® valve system. The procedure was complicated by rupture of the valve-deployment balloon, with separation and retention of the nose cone of the RetroFlex 3^® delivery system in the iliac artery. Our endovascular retrieval of the equipment was successful, and we achieved access-site hemostasis by deploying a covered stent. To our knowledge, this is the first report of the endovascular retrieval of a malfunctioning delivery system during transcatheter aortic valve replacement.

Aortic rupture following a covered stent for coarctation: delayed recognition.

Primary stenting for aortic coarctation is frequently used in adult patients. Aortic rupture remains an infrequent complication. A number of strategies, including the use of covered stents, have been proposed to reduce the risk of this catastrophic complication. We describe a 51-year-old female who underwent stenting of aortic coarctation using a covered stent, which was complicated by aortic rupture. Treatment consisted of placement of an additional covered stent to seal the site of aortic disruption. The prevention and management of aortic rupture complicating aortic coarctation stenting are discussed.     

Endovascular treatment of aortic rupture during angioplasty for aortic in-stent restenosis in aortoarteritis.

Aortic rupture during balloon angioplasty for in-stent restenosis without attempting to overexpand it is a rarity. We report a case of a young woman with aortoarteritis who had aortic rupture during angioplasty for in-stent restenosis. The balloon used was of the same diameter as the previously implanted stent and was completely within the stent during inflation. The disruption was successfully treated by percutaneous placement of a self-expandable endovascular stent graft.

Endovascular treatment for the spontaneous rupture of a non-aneurysmal subdiaphragmatic aorta

The case of a patient who underwent an endovascular aortic repair for a spontaneous rupture of a non-aneurysmal subdiaphragmatic aorta without trauma, infection, or inflammation is reported. The patient is a 51-year-old male diagnosed with subdiaphragmatic aortic rupture and was in a state of hemorrhagic shock upon admission to the hospital. Intraoperative aortography revealed the abdominal aortic rupture site located above the celiac artery. A coated thoracic stent graft was used. Completion angiography showed a total exclusion with no endoleaks. After six months of follow-up, computed tomographic scans confirmed the absence of endoleaks or graft displacements.     

Focal atherosclerotic abdominal aortic stenosis

We report a case of a 54-year-old woman presenting a symptomatic focal atherosclerotic abdominal aortic stenosis. Computed tomographic angiography allowed to study the lesion, the abdominal aorta and its main branches. The patient was treated via an endovascular approach using a covered stent. The postoperative course was uneventful and the patient was asymptomatic with a patent reconstruction after 18 months. Improvement in endovascular technology has totally modified the treatment of focal atherosclerotic abdominal aortic stenosis. However, many technical points remain to be determined including the necessity of systematic stenting, the type of stent to use, and the steps of the procedure.

Aortic Pseudo Aneurysm Complicating Coarctation Stenting Successfully Treated with a PTFE Balloon Expandable Covered Stent

Percutaneous stenting of both native and recurrent coarctation of the aorta has become an acceptable alternative to surgical repair in most centers throughout the world. Severe complications such as aortic rupture, dissection, and late pseudo aneurysm formation are rare but worrisome complications. In many countries, commercially available balloon expandable covered stents designed for intravascular use are used either for primary stenting, or in treating complications once identified. These endovascular stents, however, are not available in the United States. We report the use of a commercially available covered stent, which has been approved by the Food and Drug Administration for tracheal use, to exclude an aortic pseudo aneurysm that was identified late after stenting a native coarctation.     

覆膜支架腔内治疗急性胸主动脉综合征

目的 评价覆膜支架腔内治疗急性胸主动脉综合征的有效性和安全性。方法 2001年5月至2005年12月应用覆膜支架治疗57例急性胸主动脉综合征患者,其中急性主动脉B型夹层45例,穿透性粥样硬化性溃疡（PAU）或假性动脉瘤9例,创伤性胸主动脉瘤3例。建立数据库,分析其临床特点、疗效及随访结果。结果 57例患者覆膜支架置入技术成功率100％。5例有近端内漏,1例术中出现升主动脉夹层,未予特殊处理,随访结果良好;1例术后7天出现升主动脉夹层并发心包填塞死亡。5例PAU或主动脉夹层合并冠心病患者,在应用覆膜支架成功完全封闭破口后立即行冠状动脉介入治疗成功。1例出现术后一过性双下肢无力,经静脉滴注山莨菪碱和甘露醇2天后痊愈。1例支架覆盖左锁骨下动脉开口导致左椎动脉缺血,嗜睡2天后自行好转。术后重症监护病房时间1～8（平均3．5）天,术后平均住院10天。术后30天内死亡2例,1例死于升主动脉夹层破裂,1例死于急性肾衰竭。术后30天内死亡率3．5％。术后平均随访（25．3±13．1）（13—55）个月。1例于术后3个月死于大咯血,1例死因不明。1例因近端内漏行二次腔内修复术。5例患者因降主动脉覆膜支架远端再发现破口,行二次腔内修复术。术后截瘫发生率为0,无支架移位、狭窄等并发症。术后住院及随访期内总死亡率为7．0％。与传统手术相比,腔内治疗急性胸主动脉综合征具有创伤小、严重并发症少、住院时间较短的优势。结论 覆膜支架是治疗急性胸主动脉综合征优良且有效的方法,也可用于外科手术高风险患者,近中期随访结果良好,远期结果有待于进一步随访。

Rupture aiguë post-traumatique de l’aorte thoracique en double foyer

Purpose

Traumatic thoracic aortic rupture are commonly localised in one site essentially in the aortic isthmus but multiple localisation are not uncommon. The authors reported the case of a young man who had a double localisation of RTA after a violent car accident.

Case report

A 23-year-old man had a violent car crush involving sudden deceleration. He had multiple injuries essentially: a traumatic thoracic injury with acute posttraumatic aortic rupture in double localization, in the isthmus and in the descending thoracic aorta. He underwent thoracic endovascular aortic repair (TEVAR) with the use of stent graft three weeks after his car accident. The endovascular treatment was successful and no case of perigraft leakage has been detected during a meaning follow-up of five months.

Conclusion

The systematic analysis of the whole thoracic aortic vessel is crucial to not misdiagnose eventual multiple aortic rupture.     

Fatal late multiple emboli after endovascular treatment of abdominal aortic aneurysm. Case report.

BACKGROUND: The short term experience of endovascular treatment of abdominal aortic aneurysms (AAA) seems promising but long term randomised data are lacking. Consequently, cases treated by endovascular procedures need to be closely followed for potential risks and benefits. CASE REPORT: A 70 year-old mildly hypertensive male without previous or present arteriosclerotic, pulmonary, or urological manifestations was subjected to endovascular treatment after his mass-screening diagnosed abdominal aortic aneurysm had expanded to above 5 cm in diameter, the aneurysm having been found by CT-scanning and arteriography to be endovascularly treatable. A Vanguard bifurcated aortic stent graft was implanted under epidural/spinal anaesthesia and covered by cephalosporine and heparin (8000 IE) protection. Apart from treatment of a groin haematoma and stenosis of the left superficial femoral artery, the postoperative period presented no problems. A few days before the monthly follow-up visit, the patient developed uraemia, gangrene of one foot and dyspnoea. Blood glucose and LDH was elevated. Deterioration led to death a month and a half after stent implantation. Autopsy showed extraordinary large, extensive soft, brown vegetations in the lower part of the thoracic aorta above the properly infrarenally-placed stent. Microscopic examination revealed multiple microemboli in the liver, spleen, pancreas, intestines, testes, and especially the kidneys. DISCUSSION: Early death from microemboli after aortic stent implantation has been reported. However, the present case developed fatal multiple microemboli so late that they could not have originated from the excluded mural thrombus. The sudden death of an otherwise healthy man of extensive microemboli is difficult to explain. The stent application may have altered the proximal flow and wall movements disposing to microemboli in the case of vegetations.     

带膜内支架治疗胸主动脉瘤

目的 探寻治疗胸主动脉瘤的新术式。方法 10例胸主动脉瘤病例，其中7例行单纯带膜血管内支架(stent-graft)治疗，3例夹层破裂(De Bakey I)患者行象鼻手术加带膜血管内支架置入术。结果 7例带膜血管内支架治疗组，5例成功，1例失败，1例术后死亡；3例夹层破裂手术病例均成功，恢复顺利，无并发症。结论带膜血管内支架为治疗胸降主动脉瘤的一种有效可靠方法；象鼻手术结合带膜内支架是治疗De BakeyI型的新方式，可降低手术并发症及术后病死率。     

In-stent restenosis and aneurysm development after bare stent implantation: rescue by e-PTFE-covered cheatham- platinum stent

We report on three cases of primary endovascular bare stenting for native aortic coarctation complicated by aortic aneurysm or in-stent stenosis because of neointimal proliferation that were successfully treated by covered stent. These cases show how the deployment of a covered stent may be a safe and definitive therapeutical option in the management of these complications.     

Endovascular Treatment of Acquired Atheromatous Postsubclavian Aortic Coarctation

Coral reef aorta is a rare calcifying obstructive disease that involves the thoracoabdominal aorta. Similar presentations in the postsubclavian aorta may result in acquired atheromatous aortic coarctation leading to systemic hypertension and heart failure. The associated calcification makes surgical anatomic or extraanatomic bypass and thromboendarterectomy challenging. Extensive circumferential calcification often precludes endovascular intervention. We present the case of a 25-year-old man with an acquired atheromatous coarctation of the postsubclavian aorta who underwent successful endovascular treatment with use of a balloon-expandable covered stent.     

A quick fix: graft rescue for iatrogenic pseudoaneurysm

We present a case of delayed rupture of a femoro-popliteal saphenous vein bypass graft after stent-supported angioplasty, resulting in a large, severely symptomatic pseudoaneurysm of the thigh. This was successfully treated with deployment of a covered stent graft. The possible mechanisms of pseudoaneurysm formation in this case are discussed, and a brief review of the literature regarding the endovascular management of this clinical entity is offered.
