The patient was a 70-year-old woman with an asymptomatic aneurysm of the distal aortic arch, and thoracic endovascular aortic repair was performed. The patient showed a blood pressure difference between the left arm and the right arm on postoperative day (POD) 17 prompting the performance of a chest computed tomography scan which revealed stent graft collapse. She then underwent staged debranching of thoracic endovascular aortic repair. Stent graft collapse is a rare but well-described complication of thoracic endovascular repair. Therefore, patients who undergo such a procedure should be carefully monitored for signs and symptoms, which suggest the possibility of stent collapse.展开更多

METHODS We performed a narrative review about psychological issues in adults with IE and TAD. Through the electronic databases, Pub Med and Psyc INFO, we searched full manuscripts in English and published until September 1, 2014. RESULTS We found sixteen studies exploring psychological issues in patients with IE(six studies) and in TAD(ten papers). Psychological issues assessed were quality of life, depression, anxiety and posttraumatic stress disorder. Quality of life was explored in IE(four papers) and in TAD(eight papers). Depression and anxiety were analyzed in TAD only(five papers). Post-traumatic stress disorder was assessed in IE(one study). Quality of life was found impaired in three of four studies about IE and in three of eight studies about TAD. Posttraumatic stress disorder was present in 11% and was associated with lower levels of quality of life in IE patients. In TAD patients, anxiety and depression levels after different invasive interventions did not differ. CONCLUSION Sixteen studies report about psychological issues in IE and TAD. Most of them explore quality of life and to a less extent anxiety and depression.展开更多

Methods: Since September 1998, Endovascular Graft Exclusion for thoracic aortic dissection has been performed on 10 patients. Graft was constructed from self-expanding Z-stents covered with a woven Dacron polyester fabric graft. Ged dimensions were determined ftom spiral computed tomographic scans. All operations were performed under DSA guidance. Results: There was one early death resulting from endoleaks. Proedures in the other 9 patients succeeded. No complications such as myocardial infarction, lung failure, kidney failureand paralysis that commonly occurred ther conventional operations were obsered. Immediate thrombosis in false lumen was achieved in 6 patients, and late thrombosis occurred in 3 patients. Mean follow-up duration was 3 months, the aneurysmal diameter was decreased obviously. Conclusion: These early results support the hypothesis that Endovascular Graft Exclusion may be a safe and durable treatment for selected patients with theracic aortic dissection. Endoleak may allow continued aneurysmal expansion and rupture. Further follow-up is necessary to evaluate the true long-term effectiveness of this procedure.展开更多

Excellent results in 24 consecutive AAAD patients with just one hospital mortality. <strong>Conclusions:</strong> We believe we are entering a new phase in the treatment of AAAD, facilitated by the availability of a hybrid prosthesis which combines expanding stent technology with familiar surgical graft material. Our particular management of the left subclavian artery and of the cerebral circulation during implantation has contributed to an expeditious and reproducible method of treating dissection within the arch of the aorta and beyond.展开更多

This article adds three cases of blunt thoracic aortic injuries in pediatric patients to the literature and analyzes these in conjunction with several of the previous case series which have been published. Methods: Three cases were reviewed along with 38 previously reported cases in an attempt to identify trends in demographics and management. The three new cases presented over a four year period. All are male. A six year old and a 17-year-old were involved in motor vehicle crashes and a 10-year-old was struck by a vehicle while skateboarding. Results: The 6-year-old and the 17-year-old were treated non-interventionally due to severe closed head injuries. One received beta blockade. Both survived. The third, without head injury, underwent interposition graft and also survived. Conclusions: These findings are not greatly dissimilar from the adult experience. In reviewing all 41 pediatric cases, findings reveal a high mortality, predominantly due to head injury as well as the aortic injury. Open repair and interposition grafting continue to be the mainstay of management, with endovascular procedures and non-operative management becoming more prevalent recently. The role of beta-blockade is unclear in children with this injury. Further multicenter prospective studies of this rare pediatric injury may be useful.展开更多

This RCT will clarify the impact of GDFHT with ΔVpeak and DM on postoperative outcome in terms of morbidity, length of stay in the intensive care unit (LOSICU), length of mechanical ventilation (LMV) and length of hospital stay (LOS) in children. To determine values of ΔVpeak, DM and VTI predictive of these postoperative outcomes, an observational pilot study will be realized. This pilot study is described here. The primary objective of this study is to determine values of ΔVpeak, DM and ITV predictive of postoperative outcome in children in terms of morbidity. The secondary objectives are to determine values of ΔVpeak, DM and ITV predictive of LOSICU, LMV, LOS, intraoperative, postoperative fluid administration and vasoactive-inotropic therapy. Methods: 500 - 1000 children aged less than 18 years will be included prospectively. Statistic analysis will be realized with XLSTAT 2019.4.2 software or plus. Results and Conclusions: This trial protocol will determine values of ΔVpeak, DM and ITV with echocardiography predictive of postoperative outcome in children.展开更多

In retrograde TAAD (r-TAAD) cases, some authors reported the efficacy of thoracic endovascular aortic repair (TEVAR). However, only a few reports chose TEVAR for the treatment of r-TAAD resulting in cardiac arrest before hospital arrival. We report a case of r-TAAD presenting with cardiac arrest before hospital arrival not indicated for surgery but TEVAR as treatment. <strong>Case: </strong>A 65-year-old woman with a history of Marfan syndrome presented to the emergency department after a CPA. Sequential return of spontaneous circulation was achieved 27 min after CPA. Contrast-enhanced computed tomography showed retrograde r-TAAD with an entry tear to the false lumen in the thoracic descending aorta. Therefore, thoracic endovascular aortic repair (TEVAR) was performed with r-TAAD. Afterward, the clinical course was stabilized. This patient suggests that TEVAR is an effective option for the treatment of patients with hemodynamically unstable r-TAAD, even after CPA. <strong>Conclusion:</strong> TEVAR can lead to a successful recovery from cardiac arrest due to r-TAAD.展开更多

文摘We present a case of stent graft collapse after performing thoracic endovascular aortic repair with a custom-made fenestrated stent graft. The patient was a 70-year-old woman with an asymptomatic aneurysm of the distal aortic arch, and thoracic endovascular aortic repair was performed. The patient showed a blood pressure difference between the left arm and the right arm on postoperative day (POD) 17 prompting the performance of a chest computed tomography scan which revealed stent graft collapse. She then underwent staged debranching of thoracic endovascular aortic repair. Stent graft collapse is a rare but well-described complication of thoracic endovascular repair. Therefore, patients who undergo such a procedure should be carefully monitored for signs and symptoms, which suggest the possibility of stent collapse.

文摘<strong>Background and Aim:</strong> Reports on recovery from Stanford type A aortic dissection (TAAD) leading to cardiopulmonary arrest (CPA) are few. In retrograde TAAD (r-TAAD) cases, some authors reported the efficacy of thoracic endovascular aortic repair (TEVAR). However, only a few reports chose TEVAR for the treatment of r-TAAD resulting in cardiac arrest before hospital arrival. We report a case of r-TAAD presenting with cardiac arrest before hospital arrival not indicated for surgery but TEVAR as treatment. <strong>Case: </strong>A 65-year-old woman with a history of Marfan syndrome presented to the emergency department after a CPA. Sequential return of spontaneous circulation was achieved 27 min after CPA. Contrast-enhanced computed tomography showed retrograde r-TAAD with an entry tear to the false lumen in the thoracic descending aorta. Therefore, thoracic endovascular aortic repair (TEVAR) was performed with r-TAAD. Afterward, the clinical course was stabilized. This patient suggests that TEVAR is an effective option for the treatment of patients with hemodynamically unstable r-TAAD, even after CPA. <strong>Conclusion:</strong> TEVAR can lead to a successful recovery from cardiac arrest due to r-TAAD.
文摘Non-A non-B aortic dissection(AAD)is an infrequently documented condition,comprising of only a small proportion of all AADs.The unique anatomy of the aortic arch and the failure of the existing classifications to adequately define individuals with non-A non-B AAD,have led to an ongoing controversy around the topic.It seems that the clinical progression of acute non-A non-B AAD diverges from the typical type A and B dissections,frequently leading to serious complications and thus mandating early intervention.Currently,the available treatment methods in the surgical armamentarium are conventional open,endovascular techniques and combined hybrid methods.The optimum approach is tailored in every individual case and may be determined by the dissection’s location,extent,the aortic diameter,the associated complications and the patient’s status.The management of non-A non-B dissections still remains challenging and a unanimous consensus defining the gold standard treatment has yet to be reached.In an attempt to provide further insight into this perplexing entity,we performed a minireview of the literature,aiming to elucidate the epidemiology,clinical course and the optimal treatment modality.
文摘Objective The optimal treatment for chronic type B dissection remains controversial. The purpose of this study was to report early and mid-term results of thoracic endovascular aortic repair (TEVAR) of chronic type B aortic dissection. Methods From June 2001 to September 2007, 84 patients with chronic type B aortic
文摘Objective To summarize the clinical study of modified total aortic arch replacement and stent elephant trunk technique treatment to patients with DeBakey Ⅰ thoracic aortic dissection. Methods From January 2006 to October 2010,101 cases of DeBakeyⅠaortic dissection were treated by modified total arch replacement and stent elephant trunk technique,in which emergencey surgery were performed on 73 cases. There were 76 male and 25
