发生于大动脉的外科疾病主要是真性动脉瘤、夹层动脉瘤和假性动脉瘤等动脉扩张病。早在1684年,Moore将一段金属丝导入腹主动脉瘤腔内,希望促发瘤内血栓形成。这是人类的首次大动脉腔内治疗尝试,而其真正的发展仅仅是最近20年的事。上世纪80年代中后期开始了动脉瘤腔内隔绝系统的实验研究,到1990年,Parodi成功地施行了世界上第一例腹主动脉瘤腔内隔绝术,在国内,笔者于1997年率先开展了该手术[1],并在此后迅速推广应用于胸主动脉瘤、夹层动脉瘤、假性动脉瘤和动静脉瘘等疾病的治疗。1主动脉真性动脉瘤的腔内治疗发生在主动脉的真性动脉瘤可分…  相似文献

OBJECTIVE: The purpose of this study was to determine, on the basis of the late fate of the intact aortic arch with abnormal tissue after aortic root replacement, whether the intact aortic arch should be replaced prophylactically at the time of aortic root replacement for annuloaortic ectasia in Marfan syndrome. METHODS: A retrospective review was performed in 85 patients with Marfan syndrome who underwent aortic root replacement for annuloaortic ectasia with or without aortic dissection (mean age 37 years, range 19-61 years). These 85 patients were divided into four groups according to the postoperative condition of the residual aorta. In group I (n = 47), the patients underwent aortic root replacement for annuloaortic ectasia with or without localized dissection in the ascending aorta. In these patients the residual aorta, including the aortic arch, was therefore intact. In group II (n = 10), the aortic arch was intact, although the descending thoracic aorta was dissected because of the preoperative type B dissection. In groups III and IV, the patients had type A dissection involving the transverse arch associated with annuloaortic ectasia. In group III (n = 13), residual dissection existed in the descending thoracic aorta after concomitant total arch replacement. In group IV (n = 15), the aortic arch and the descending thoracic aorta were dissected. RESULTS: There were 5 early deaths (3 in group I, 1 in group II, and 1 in group III). Subsequent operations were required in 10, 5, 6, and 7 cases in groups I, II, III, and IV, respectively. Regarding the aortic arch, only 2 of 53 survivors of the initial hospitalization with an intact aortic arch (groups I and II) underwent subsequent total arch replacement for the onset of dissection in the aortic arch, and 4 of 14 survivors of the initial hospitalization with a residual dissecting arch (group III) needed subsequent total arch replacement. Actuarial freedom from arch repair among patients with an intact aortic arch (91% at 15 years) was significantly higher than that among patients with a residual dissecting arch (49% at 15 years, P =.0078). CONCLUSIONS: The incidence of new dissection in the residual intact arch after aortic root replacement was extremely low. Therefore prophylactic replacement of the intact arch does not appear to be necessary at aortic root replacement for annuloaortic ectasia in Marfan syndrome.  相似文献

Thoracic endovascular aortic repair (TEVAR) may involve either planned or inadvertent coverage of aortic branch vessels when stent grafts are implanted into the aortic arch. Vital branch vessels may be preserved by surgical debranching techniques or by placement of additional stents to maintain vessel patency. We report our experience with a double-barrel stent technique used to maintain aortic arch branch vessel patency during TEVAR. Seven patients underwent TEVAR using the double-barrel technique, with placement of branch stents into the innominate (n = 3), left common carotid (n = 3), and left subclavian (n = 1) arteries alongside an aortic stent graft. Gore TAG endografts were used in all cases, and either self-expanding stents (n = 6) or balloon-expandable (n = 1) stents were utilized to maintain patency of the arch branch vessels. In three cases the double-barrel stent technique was used to restore patency of an inadvertently covered left common carotid artery. Four planned cases involved endograft deployment proximally into the ascending aorta with placement of an innominate artery stent (n = 3) and coverage of the left subclavian artery with placement of a subclavian artery stent (n = 1). TEVAR using a double-barrel stent was technically successful with maintenance of branch vessel patency and absence of type I endoleak in all seven cases. One case of zone 0 endograft placement with an innominate stent was complicated by a left hemispheric stroke that was attributed to a technical problem with the carotid-carotid bypass. On follow-up of 2-18 months, all double-barrel branch stents and aortic endografts remained patent without endoleak, migration, or loss of device integrity. The double-barrel stent technique maintains aortic branch patency and provides additional stent-graft fixation length during TEVAR to treat aneurysms involving the aortic arch. Moreover, the technique uses commercially available devices and permits complete aortic arch coverage (zone 0) without a sternotomy. Although initial outcomes are encouraging, long-term durability remains unknown.  相似文献

We summarize our experience out of 133 operations involving the aortic arch which were performed in 130 patients throughout the last 13 years. Aortic pathology was aneurysmal disease in 57 cases, acute aortic dissection in 44, and chronic aortic dissection in 29 patients. Operative strategies included partial replacement or repair of the aortic arch in 80 cases and subtotal or total replacement of the transverse arch in 53 patients. In 19 cases presenting with aneurysms of the descending thoracic aorta, implantation of an elephant trunk prothesis was performed simultaneously. The operations were performed during circulatory arrest (10-64 min, mean: 27 min) and in deep hypothermia (nasopharyngeal temperature: 11-25 degrees C). Recently, two modifications of the technique were introduced: First, the site of arterial inflow cannulation is changed by intubating the prothesis directly during reperfusion providing antegrade perfusion. Second, in patients with acute aortic dissection, the false lumen of the aortic root and arch is filled with resorcinformol glue and the layers are readapted by this means after anatomical reconstruction. Overall, early mortality was 14.3% and was much higher in acute dissection (22.7%) when compared to chronic dissection (6.9%, p = 0.110). A total of 24 reoperations were necessary in 16 patients of this group with subsequent replacement of the descending thoracic aorta being most frequently performed (n = 14). Actuarial survival after 5 years was not significantly different between the groups (69.1%) but showed a progressive decline for patients with aneurysms and chronic dissection (11 late deaths) while no late deaths occurred in acute dissections.(ABSTRACT TRUNCATED AT 250 WORDS)  相似文献

OBJECTIVES: Extensive aortic replacement, such as concomitant aortic root and arch replacement, thoracoabdominal aortic repair, and complete thoracic aorta replacement, remains controversial. We studied surgical morbidity and mortality in patients undergoing concomitant aortic root and arch replacement, and those undergoing secondary replacement of the thoracoabdominal aorta after this preceding procedure. SUBJECTS AND METHODS: Between January, 1987 and March 1999, 21 patients (mean age: 52 years) underwent concomitant aortic root and arch replacement involving 3 surgical procedures--aortic root replacement with composite graft and arch (n = 12), aortic root replacement with valve sparing and arch (n = 4), or aortic root replacement with composite graft and arch and elephant trunk (n = 5). RESULTS: Overall hospital mortality was 4.8%. Six patients (mean age: 42 years) underwent secondary thoracoabdominal aorta replacement after the concomitant root and arch procedure. The mean time until secondary surgery was 9.5 months. There was 1 hospital death. CONCLUSION: Concomitant replacement of the aortic root and arch, or secondary replacement of the thoracoabdominal aorta after concomitant root and arch replacement can be conducted with low surgical morbidity and mortality.  相似文献

OBJECTIVE: Recurrent aortic narrowing after repair of aortic coarctation or interrupted aortic arch, as well as diffuse, long-segment aortic hypoplasia, can be difficult to manage. Extra-anatomic ascending aorta-descending aorta bypass grafting through a sternotomy is an alternative approach for this problem. METHODS: Since 1985, 19 patients aged 2 months to 18 years (mean 10.7 years) underwent extra-anatomic bypass with 10- to 30-mm Dacron grafts. The initial diagnosis was coarctation with hypoplastic arch in 15, interrupted aortic arch in 3, and diffuse long-segment aortic hypoplasia in 1. Seventeen of the children had a total of 22 previous operations: transthoracic interposition or bypass graft (n = 7), end-to-end anastomosis (n = 7), subclavian arterioplasty (n = 6), and synthetic patch (n = 2). The mean time from initial repair was 8.0 years (range 0.6-18 years). Three children had previous sternotomies. Cardiopulmonary bypass was avoided in all but 6 patients (5 with simultaneous intracardiac repairs). RESULTS: No hospital or late deaths occurred. On follow-up from 4 months to 14.7 years (mean 7.9 years), no reoperations for recurrent stenosis were performed. Two patients have arm-to-leg pressure gradients: 20 mm Hg at rest in 1 patient and a 60-mm Hg systolic exercise gradient with no resting gradient in the other. One patient required exclusion of an aortic aneurysm at the old coarctation repair site 13 years after extra-anatomic bypass. Three children had subsequent successful cardiac operations. CONCLUSIONS: Extra-anatomic bypass is an effective and relatively easy approach for selected cases of complex or reoperative aortic arch obstruction. It should be considered as an alternative operative technique for complex aortic arch reconstruction.  相似文献

Sixty-seven operations were performed in 59 patients for aneurysmal disease occurring after previous operations involving the ascending aorta and transverse aortic arch. The initial aortic pathological condition included the following: fusiform aneurysm due to medial degenerative disease in 34 patients, 12 of whom had Marfan's syndrome; aortic dissection in a previously undilated aorta in 23; and aneurysm persisting or occurring after brachiocephalic bypass in 2. One of the latter had an aneurysm because of aortitis. Various operations initially performed did not completely treat the disease, and certain complications occurred spontaneously, including infection and dissection. The residual pathological condition led to the development of aortic insufficiency, aortic dissection, coronary artery insufficiency, and progressive aneurysmal dilatation. These complications were treated by composite valve graft replacement of the aortic valve and ascending aorta or the transverse aortic arch or both, simple aortic valve replacement, graft replacement of the ascending aorta or arch or both, and suture of false aneurysm with viable tissue wrap. Twenty patients (34%) had an aneurysm of the distal aorta. The entire aorta was replaced in 3, thoracoabdominal segments in 9, and the abdominal aorta in 1. Of the 59 patients, 49 (83%) were early survivors and 40 (68%) were alive on January 1, 1985. Principles of therapy that may have prevented the complications leading to reoperation include aneurysm replacement at the time of aortic valve replacement and coronary artery bypass; total replacement of the ascending aorta and aortic valve in patients with Marfan's syndrome; the same procedure or aortic valve replacement and separate graft replacement in patients with non-Marfan's medial degenerative disease; ascending aortic replacement in all patients with dissection combined with valve resuspension, aortic valve replacement, or composite valve graft depending on the involvement of the aortic sinuses and the presence of aortic insufficiency.  相似文献
