Aortic arch reconstruction remains a challenge for the cardiothoracic surgeon. We present our simplified technique in which we used two grafts for arch reconstruction without circulatory arrest. It is a relatively easy and quick technique consisting of a unique modification of the selective antegrade cerebral circulation system without the need for circulatory arrest in selected cases. 相似文献

This case illustrates an unusual and fatal complication after endovascular treatment of type B aortic dissection and highlights the role of echocardiography in the early diagnosis of complications. In this case, a patient with previous diagnosis of chronic type B aortic dissection and moderate aortic regurgitation underwent endovascular repair of the proximal descending aorta and conservative surgical correction of the aortic valve. On early postoperative, a transesophageal echocardiogram and aortic angiotomography demonstrated proximal endoleak by contrast extravasation around the proximal graft attachment site, causing compression of the stent in its middle portion, resulting in narrowing with reduced cross‐sectional area. 相似文献

Ascending aorta replacement for acute aortic dissection repair was carried out in a 29-year-old man without the use of blood or blood products. Intraoperative blood loss was minimized with the use of biological glues and red cell salvage. Erythropoietic agents were started before surgery and continued during and after operative repair. Postoperatively, oxygen balance was maintained despite very low hemoglobin levels by increasing the cardiac output to compensate for the low oxygen-carrying capacity, thus maximizing oxygen delivery. Only essential laboratory determinations were carried out, which reduced additional blood loss. Repair was successful, and the patient was discharged from the hospital despite a delay in diagnosis and definitive surgical repair. 相似文献

Surgical treatment for acute type A aortic dissection in pregnancy: a case of aortic root replacement just after Cesarean section 总被引:2,自引:0,他引:2

A 25-year-old woman with Marfan syndrome in the 37th week of pregnancy was referred for acute chest pain and dyspnea. An emergency Cesarean section was performed because of fetal distress. Intraoperative echocardiography at the end of the Cesarean section showed dilatation of the aortic root and dissection of the ascending aorta. The patient underwent replacement of the aortic root and the ascending aorta on the following day because of uterine bleeding. The postoperative course was uneventful for the mother and her baby. 相似文献

Acute type A aortic dissection is a surgical emergency. Treatment is based on dissected ascending aortic replacement and correction of an associated aortic insufficiency. Catheterization of the axillary artery, open distal anastomosis and systematic resection of the intimal tear are the main surgical evolutions of the last years. They allowed to significantly reduce intraoperative mortality rate particularly due to bleeding. Thirty days mortality rate of operated aortic dissection is about 20 to 30%. Visceral malperfusion syndromes induced by aortic dissection represent an important cause of postoperative death. An early diagnosis and treatment appears necessary. Thoracoabdominal CT scan allows understanding mechanisms inducing malperfusion. Aortography and an emergency endovascular procedure allow restoring arterial blood flow before renal or mesenteric irreversible ischemia. Collaboration between radiologist, anesthesiologist and surgeon is necessary to optimize survival of acute type A aortic dissection. 相似文献

There are at least 7000 aortic dissections diagnosed in the United States each year. Type B dissections accounted for 38% of cases enrolled in the prospective International Registry of Aortic Dissection. We report a case of a 48-year-old hypertensive woman with an acute type B aortic dissection causing significant dynamic obstruction of the aorta. Intravascular ultrasound of her aorta revealed a mobile intimal flap nearly obliterating the true lumen with each systolic contraction. Simultaneous pressure tracings obtained from her ascending aorta and femoral artery demonstrated a systolic pressure gradient in excess of 100 mm Hg. The patient developed progressive renal failure and ultimately underwent successful operative replacement of the proximal descending thoracic aorta with a Dacron graft. In this case presentation, we highlight the unusual physiology exemplified by this case and explore contemporary management strategies for complicated type B aortic dissection, including surgery and catheter-based techniques. 相似文献

Acute aortic dissection (AAD) is the most common aortic catastrophe. The mortality rate of type A dissection approaches 40% to 50% in 48 hours. Causes of death include rupture, aortic insufficiency, or malperfusion involving the coronary arteries, head vessels, visceral arteries, and lower extremities. Other acute aortic conditions can be confused with AAD. Emergent surgery is usually recommended, although there are some situations in which initial management of malperfusion or conservative therapy can be considered prior to proximal aortic repair. Various surgical techniques are employed to manage AAD. This article reviews the etiology, clinical presentations, and management of patients with type A AAD. 相似文献

Objective: We presented initial results of less invasive quick replacement (LIQR) with moderate hypothermic arrest without cerebral perfusion followed by aggressive rapid re-warming to shorten the duration of brain ischemia, eardiopulmonary bypass (CPB), and overall surgery (J-TCVS 2008). We then assessed the mid-term outcomes and quality of life for octogenarian patients who undergo the LIQR for type A acute aortic dissection (AAD). 相似文献

PURPOSE: To evaluate midterm results of endovascular stent-graft placement for acute Stanford type B dissection (TBD). METHODS: A retrospective review was conducted of 35 consecutive patients who were treated with stent-graft implantation for acute TBD between July 1996 and July 2007. Computed tomographic (CT) volumetric analysis of the true lumen (TL) and false lumen (FL) changes in 23 patients was performed, as well as evaluation of the influence of re-entry points and length of stent-graft coverage on volume changes. In addition, complications were evaluated. Follow-up was performed at 6 and 12 months and yearly thereafter. RESULTS: The technical success rate was 82.7%, and the 30-day mortality rate was 8.5%. Mean follow-up was 34 months. The overall survival rate at 5 years was 78.4%. Complications included retrograde type A dissections in 3 patients during the perioperative period and in 1 patient during midterm follow-up. In addition, 5 early and 3 late endoleaks were observed. Three patients were converted to open surgery and 2 needed secondary interventions. In the stented segment, stabilization of the aorta was achieved even during midterm follow-up, with a TL volume increase of 59% at 5 years and nearly stable FL volume. The segment from the distal end of the stent-graft to the celiac artery, however, showed unstable TL and FL volumes, with high standard deviations after the first postinterventional year and circumferential aneurysmal dilatation of the aorta immediately adjacent to the stent-graft in 5 patients. The abdominal aorta showed no substantial volume changes over time. The length of stent-graft coverage and the occurrence of re-entries greatly influenced FL volume changes distal to the stent-graft. CONCLUSION: Serious complications can occur during and after endovascular repair of TBD. Therefore, it should be reserved for high-risk patients. 相似文献
