ABSTRACT

Objective:To investigate the risk factors of postoperative continuous renal replacement therapy application in Stanford type A acute aortic dissection.Methods:This retrospective study included 527 patients with Stanford type A acute aortic dissection from November 2015 to February 2018 in Beijing Anzhen Hospital. They were divided into 2 groups according to whether or not needed postoperative continuous renal replacement therapy, group CRRT(78 cases) and group None CRRT(449 cases). Binary logistic regression analysis was used to analyze the risk factors of continuous renal replacement therapy. Results:Of all the patients, the percentage of using continuous renal replacement therapy was 14.8%(78/527), and the mortality of 30 days after surgery was 8.5%(45/527). The independent risk factors associated with CRRT were preoperative serum creatinine(sCr)( OR=1.012, 95% CI: 1.005-1.019, P<0.001), transfusion of red blood cell in surgery( OR=1.141, 95% CI: 1.071-1.216, P<0.001), transfusion of platelet in surgery( OR=1.307, 95% CI: 1.084-1.576, P=0.005), the total amount of drainage( OR=1.000, 95% CI: 1.000-1.000, P=0.036), and the time of extubation after surgery( OR=1.004, 95% CI: 1.001-1.008, P=0.013). Conclusion:The risk factors of CRRT after emergency surgery of Stanford type A acute aortic dissection are preoperative serum creatinine, transfusion of red blood cell in surgery, transfusion of platelet in surgery, the total amount of drainage and the time of tracheal extubation after surgery. We need to focus on those risk factors in our daily job and manage them timely and properly, in order to improve patients’ prognosis.

ABSTRACT

A 76-year-old man with a history of total esophagectomy and retrosternal gastric tube reconstruction for esophageal cancer was transferred to our hospital because of consciousness disorder. It became an emergency operation on diagnosis of Stanford type A acute aortic dissection on enhanced CT. Because CT showed the retrosternal gastric tube ran along the right side of the body of the sternum through the back side of the manubrium, we opted for skin and the suprasternal incision on the left side from center. We could perform total aortic arch replacement without the damage of the gastric tube except that the right side of the operative view was slightly poor. We did not recognize digestive organ symptoms such as postoperative passage disorders nor mediastinitis. The patient was discharged from our hospital on postoperative day 24.

ABSTRACT

<b>Objective</b> : Although dissection extending to the aortic root is a common finding, it is potentially fatal in patients with acute type A aortic dissection. The purpose of this study was to evaluate surgical results of acute type A aortic dissection with proximal involvement. The proximal extension of dissection, types of aortic root procedure and its feasibility were investigated. <b>Methods</b> : Between 1997 and 2011, 80 patients with acute type A aortic dissection underwent emergent operation. <b>Results</b> : Dissection reaching around the coronary artery orifice was observed in 28 patients. In 11 patients, both left and right coronary arteries were involved with aortic dissection. Aortic root replacement was performed in 4 patients. In 7 patients, the dissected aortic root was reinforced by GRF glue and proximal aorta was replaced with a graft. Among these patients, postoperative aortic root redissection with severe aortic regurgitation was observed in 5 patients during postoperative long-term periods. All of them required surgical re-intervention of the aortic root. In 17 patients, dissection was extended to the right coronary artery. Aortic root reconstruction was performed in 2 patients due to pre-existing annulo-aortic ectasia. The remaining 15 patients underwent proximal reinforcement with GRF glue. No patient showed dissection extending to the left coronary artery alone. Operative mortality was 11% and other types of complications concerning the aortic root was not observed. <b>Conclusion</b> : An acceptable outcome was demonstrated with our surgical strategy of proximal aortic dissection. For patients, in particular, with proximal involvement to both the left and right coronary arteries, redissection of the aortic root should be noticed as a late complication with considerable frequency. Special care should be taken for precise recognition of the proximal extension of dissection and appropriate surgical procedure including simultaneous aortic root replacement.

ABSTRACT

A 68-year-old woman with a sudden onset of back pain was brought to our hospital by ambulance. Computed tomography (CT) showed Stanford type A (DeBakey type II) acute aortic dissection, left hemothorax, and hematoma extending along the pulmonary artery ; therefore, the patient underwent emergency operation. We performed a median sternotomy. Pericardial effusion was not observed ; however, a hematoma was found around the ascending aorta. Preoperative CT showed left hemothorax, but pleural effusion was not observed in the left pleural cavity. The left hemothorax, which was detected on preoperative CT, was diagnosed as an extrapleural hematoma. The dissection entry site was located at the proximal aortic arch ; therefore, ascending aorta-hemiarch replacement was performed. After weaning from cardiopulmonary bypass, the patient experienced sudden airway bleeding. The bleeding was attributed to the hematoma extending along the pulmonary artery. Here, we have reported a rare case of Stanford type A acute aortic dissection with the left extrapleural hematoma and lung hemorrhage.
