Thoracic aortic aneurysms: treatment with endovascular self-expandable stent grafts

BACKGROUND: This study was performed to evaluate the safety and feasibility of endovascular stent graft placement in the treatment of descending thoracic aortic aneurysms. METHODS: Between November 1996 and February 1999, endovascular stent graft repair was used in 21 patients. There were 5 women and 16 men with a mean age of 67 years (range, 41 to 87 years). An atherosclerotic aneurysm with a diameter of more than 6 cm was the indication for intervention in 19 patients (90.5%). In 2 patients (9.5%), a localized aortic dissection with a diameter of more than 6 cm was treated. In 71.4% (15 of 21) of patients, multiple stents were necessary for aneurysm exclusion. To allow safe deployment of the stent graft, preliminary subclavian-carotid artery transposition was performed in 9 patients (42.9%). Vascular access was achieved through a small incision in the abdominal aorta (n = 6), an iliac artery (n = 8), or a femoral artery (n = 7). Talent and Prograft stent grafts were used. RESULTS: Successful deployment of the endovascular stent grafts was achieved in all patients. Two patients died postoperatively (mortality rate, 9.5%), 1 of aneurysmal rupture and the other of impaired perfusion of the celiac axis. Repeat stenting was done in 3 patients because of intraoperative leakage. CONCLUSIONS: Endovascular stent graft repair is a promising and less invasive alternative to exclude the aneurysm from blood flow. This technique allows treatment of patients who are unsuitable for conventional surgical procedures. An exact definition of inclusion criteria and technical development of stent grafts should contribute to further improvements in clinical results.     

Endovascular treatment of the descending thoracic aorta.

OBJECTIVES: to report our initial experience with endovascular stent graft repair of a variety of thoracic aortic pathology. DESIGN: retrospective single center study. MATERIAL AND METHODS: between February 2000 and January 2002, endovascular stent graft repair was performed in 26 patients: traumatic aortic isthmus rupture (n=3), Type B dissection (n=11) and descending thoracic aortic aneurysm (n=12). The deployed stent graft systems were AneuRx-Medtronic (n=1), Talent-Medtronic (n=13) and Excluder-Gore (n=12). RESULTS: successful deployment of the stent grafts in the intended position was achieved in all patients. No hospital mortality neither paraplegia were observed. Late, non procedure related, death occurred in four patients (15%). Access artery complications with rupture of the iliac artery occurred in two patients and were managed by iliac-femoral bypass. The left subclavian artery was overstented in seven patients (27%). Only the first patient received a carotido-subclavian bypass. The mean maximal aortic diameter decreased significantly in patients treated for descending thoracic aneurysm. Only one patient had an endoleak type II after 6 months without enlargement of the aneurysm. Complete thrombosis of the thoracic false lumen occurred in all but one patient treated for Type B dissection 6 months postoperatively. Two patients underwent a consecutive stent graft placement, due to a large re-entry tear distal to the first stent graft. CONCLUSIONS: endovascular stent graft repair for Type B dissection, descending thoracic aneurysm and aortic isthmus rupture is a promising less-invasive alternative to surgical repair. Further studies are mandatory to determine its long-term efficacy.

A systematic review of primary endovascular repair of the ascending aorta

Objective

Endovascular repair of the ascending aorta is currently limited to patients at high surgical risk with aortic diseases originating above the sinotubular junction. A number of different endovascular technologies and approaches have been used, although no consensus exists regarding a standardized technique. To better understand real-world endovascular approaches to the ascending aorta, we performed a comprehensive review of the types of endovascular aortic stents and associated vascular access used in repair of the ascending aorta.

背景与目的 单分支型主动脉覆膜支架及其传输系统是近年国内研发的新型支架系统,适用于锚定区不足的主动脉夹层,是累及左锁骨下动脉（LSA）主动脉夹层的新选择。笔者通过总结使用该支架系统行胸主动脉覆膜支架腔内隔绝术（TEVAR）治疗锚定区不足的急性Stanford B型的病例,评估其近期效果与安全性。方法 回顾性收集2019年4月—2020年1月,在云南省阜外心血管病医院血管外科采用Castor^?一体化分支型主动脉覆膜支架行TEVAR的Stanford B型夹层伴锚定区不足的8例患者的临床资料。分析手术过程及围手术期并发症情况。结果 8例患者中,男7例（87.5%）,女1例（12.5%）;中位年龄42（33~64）岁;BMI（25.5±3.8）kg/m²。8例均成功植入支架,初始技术成功率100%,无围手术期死亡及神经系统并发症,无I型内漏。平均住院时间为（14.8±3.7）d。平均随访时间为223（60~370）d,所有主体、分支支架血管通畅、无相关I和III型内漏,无神经系统并发症,无左上肢缺血表现。结论 应用单分支覆膜支架行TEVAR治疗Stanford B型夹层伴锚定区不足是一种安全、有效的方法,中远期疗效有待随访。     

Device related problems of thoracic stent-grafts

The outcome of the endovascular repair of abdominal aortic aneurysms seems to be device related. The presented study evaluated the outcome of endovascular procedure in cases of thoracic aortic pathology according to the implanted thoracic stent graft devices. METHODS: Since November 1999 a variety of thoracic aortic pathologies in 59 patients has been treated endovascularly. The median age of the cohort (53 males, 6 females) was 64 years (rang, 21 to 83). The patients presented the following aortic morphology: aneurysm n = 23, dissections with aneurysm n = 9, dissection without aneurysm n = 9, intramural hematoma n = 2, penetrating ulcers n = 2, transsection n = 8, false aneurysm n = 6. The underlying pathology was: atherosclerotic medial degeneration n = 25, acute dissection (< 14 days) n = 10, chronic dissection (> or = 14 days) n = 10, trauma n = 8, iatrogenic n = 6. Three patients presented the symptoms of aortic pulmonary fistulas; one patient was treated due to traumatic aortic oesophageal fistula. The used stent graft devices included the GORE TAG (n = 35), the Talent device (n = 13), the Cook device (Zenith TX 1: n = 5), and the Endofit device (n = 3). At three cases a home-made device (n = 1) or a combination of different stent grafts was implanted (Talent plus TAG, Talent plus TX1). Totally, 93 stent grafts were primarily implanted. RESULTS: The 30-day mortality was 1 / 59. One patient with acute dissection (Stanford type B) suffered from a per-procedural acute retrograde dissection leading to death in spite of the performed Bentall's procedure. Per-operatively, one patient showed cerebral ischemia, one other patient experienced a transsection of the external iliac artery due to the retraction of the introducer sheath, and another patient showed an extravasation of contrast dye. 24 hours following the endovascular procedure, one patient developed paraplegia without regression in spite of performing a spinal drainage. The passage of the introducer sheath of the primarily chosen device was impossible at three cases, in another three cases type I endoleaks were detectable, a type III endoleak was evident at another patient with formerly implanted multiple stent grafts. SUMMARY AND CONCLUSIONS: The results of the endovascular procedures in treatment of thoracic aortic pathologies demonstrated typically device related problems and unwanted events. Various types of stent grafts, introducer sheaths, and delivery systems may be necessary to satisfy the different requirements for different indications.
