		                        			OBJECTIVES:
		                        			Thoracoabdominal aortic aneurysm (TAAA) prosthetic vessel replacement is one of the most complex operations in the field of cardiovascular surgery. The key to success of this operation is to prevent and avoid ischemia of important organs while repairing TAAA. This study aims to summarize and analyze the effect of prosthetic vessel replacement under left heart bypass in the treatment of TAAA.
		                        		
		                        			METHODS:
		                        			Data of 15 patients with TAAA who underwent prosthetic vessel replacement under left heart bypass in Xiangya Hospital of Central South University were retrospectively analyzed. According to Crawford classification, there were 2 cases of type I, 8 cases of type II, 3 cases of type III, and 2 cases of type V. There were 14 cases of selective operation and 1 case of emergency operation. All operations were performed under left heart bypass, and cerebrospinal fluid drainage was performed before operation. Left heart bypass was established by intubation of left inferior pulmonary vein and distal abdominal aorta or left femoral artery. The thoracoabdominal aorta was replaced segment by segment. After aortic dissection, the kidneys were perfused with cold crystalloid renal protective solution, and the celiac trunk and superior mesenteric artery were perfused with warm blood.
		                        		
		                        			RESULTS:
		                        			One patient with TAAA after aortic dissection of type A died. During the operation, straight blood vessels were used to repair TAAA, and the celiac artery branches were trimmed into island shape and anastomosed with prosthetic vessels. After the operation, massive bleeding occurred at the anastomotic stoma, then anaphylactic reaction occurred during massive blood transfusion, resulting in death. One patient suffered from paraplegia due to ischemic injury of spinal cord. The other patients recovered well and were discharged. The postoperative ventilation time was (16.5±13.8) h and the postoperative hospital stay was (10±4) d. The amount of red blood cell transfusion was (13±9) U. The patients were followed up for 2 months to 2 years, and the recovery was satisfactory.
		                        		
		                        			CONCLUSIONS
		                        			The effect of prosthetic vessel replacement under left heart bypass in the treatment of TAAA is good, which is worthy of clinical promotion.

		                        			To evaluate the early and mid-term results after surgical repair of thoracoabdominal aortic aneurysm(TAAA)in patients with DeBakey typeⅠor Ⅲ aortic dissection. The clinical data of 130 patients who underwent TAAA repair for chronic DeBakey typeⅠ(groupⅠ, =47)or type Ⅲ(group Ⅲ, =83)aortic dissections in our center between January 2009 and December 2017 were retrospectively analyzed.Early postoperative results,midterm survival,and re-interventions were compared between these two groups. The 30-day mortality rate was 6.9%(=9)in the overall cohort,with no statistic difference between groupⅠand group Ⅲ(10.6% 4.8%;=0.803, =0.370).The incidence of major adverse events(38.3% 51.8%;=2.199, =0.138),5-year actuarial survival rate [(81.7±5.9)% (87.2±4.2)%;=0.483, =0.487],and 5-year actuarial freedom from all reinterventions [(84.5±6.7)% (85.5±4.8)%;=0.010, =0.920] showed no significant differences between these two groups. The early and mid-term outcomes after surgical repair of TAAA are similar for DeBakey typeⅠ and type Ⅲ patients.However,studies with larger sample sizes are still required.

		                        			Objective To evaluate the early and midterm results of surgical repair of thoracoabdominal aortic aneurysm(TAAA)in patients with Marfan syndrome(MFS). Methods The clinical data of patients with MFS undergoing TAAA repair in Fuwai Hospital between January 2009 and December 2017 were retrospectively analyzed.These patients were divided into two groups:MFS group(=58)and non-MFS group(=98).The baseline data,early postoperative results,and midterm follow-up outcomes were compared between these two groups. Results MFS patients were significantly younger(32 years old 45 years old,=9.603,=0.000)and more frequently had a history of aortic aneurysm or dissection(19% 0,=19.996,=0.000)than non-MFS patients.However,the proportions of males and smokers were significantly lower when compared with non-MFS patients(55.2% 80.6%,=11.489,=0.001;13.8% 46.9%,=17.686,=0.001).There was no significant difference in proportion of emergency operation,prophylactic cerebrospinal fluid drainage,operation time,intra-operative circulation management,and intra-operative blood transfusion(all >0.05).The 30-day mortality rate was significantly lower in MFS group than in non-MFS group(0 9.2%, [Formula: see text]=5.034,=0.025). Conclusions For patients with MFS,TAAA repair provides lower 30-day mortality and comparative middle-term survival.However,the re-intervention rate is higher among MFS patients,highlighting the importance of close follow-up.

		                        			OBJECTIVE:
		                        			To analyze the morphological features and forensic pathological characteristics of cardiac ruptures of different causes for their differential diagnosis.
		                        		
		                        			METHODS:
		                        			We analyzed the data of 44 autopsy cases of cardiac rupture from 2014 to 2017 in our institute, including 11 cases caused by blunt violence with intact pericardium, 4 caused by cardiopulmonary resuscitation (CPR), 9 by myocardial infarction, and 20 by aorta dissection rupture.The gross features and histopathological characteristics of cardiac rupture and pericardial effusion were analyzed and compared.
		                        		
		                        			RESULTS:
		                        			Cardiac ruptures caused by blunt violence varied in both morphology and locations, and multiple ruptures could be found, often accompanied with rib or sternum fractures; the volume of pericardial effusion was variable in a wide range; microscopically, hemorrhage and contraction band necrosis could be observed in the cardiac tissue surrounding the rupture.Cardiac ruptures caused by CPR occurred typically near the apex of the right ventricular anterior wall, and the laceration was often parallel to the interventricular septum with frequent rib and sternum fractures; the volume of pericardial blood was small without blood clots; microscopic examination only revealed a few hemorrhages around the ruptured cardiac muscular fibers.Cardiac ruptures due to myocardial infarction caused massive pericardial blood with blood clots, and the blood volume was significantly greater than that found in cases of CPR-induced cardiac rupture ( < 0.05);lacerations were confined in the left ventricular anterior wall, and the microscopic findings included myocardial necrosis, inflammatory cell infiltration, and mural thrombus.Cardiac tamponade resulting from aorta dissection rupture was featured by massive pericardial blood with blood clots, and the blood volume was much greater than that in cases of cardiac ruptures caused by blunt violence, myocardial infarction and CPR ( < 0.05).
		                        		
		                        			CONCLUSIONS
		                        			Hemorrhage, inflammatory cell infiltration, and lateral thrombi around the cardiac rupture, along with pericardial blood clots, are all evidences of antemortem injuries.

		                        			PURPOSE: Acute aortic diseases, such as aortic dissection and aortic aneurysm, can be life-threatening vascular conditions. In this study, we compared outcomes before and after the implementation of a critical pathway (CP) for patients with acute aortic disease at the emergency department (ED). MATERIALS AND METHODS: This was a retrospective observational cohort study. The CP was composed of two phases: PRE-AORTA for early diagnosis and AORTA for prompt treatment. We compared patients who were diagnosed with acute aortic disease between pre-period (January 2010 to December 2011) and post-period (July 2012 to June 2014). RESULTS: Ninety-four and 104 patients were diagnosed with acute aortic disease in the pre- and post-periods, respectively. After the implementation of the CP, 38.7% of acute aortic disease cases were diagnosed via PRE-AORTA. The door-to-CT time was reduced more in PRE-AORTA-activated patients [71.0 (61.0, 115.0) min vs. 113.0 (56.0, 170.5) min; p=0.026]. During the post-period, more patients received emergency intervention than during the pre-period (22.3% vs. 36.5%; p=0.029). Time until emergency intervention was reduced in patients, who visited the ED directly, from 378.0 (302.0, 489.0) min in the pre-period to 200.0 (170.0, 299.0) min in the post-period (p=0.001). The number of patients who died in the ED declined from 11 to 4 from the pre-period to the post-period. Hospital mortality decreased from 26.6% to 14.4% in the post-period (p=0.033). CONCLUSION: After the implementation of a CP for patients with acute aortic disease, more patients received emergency intervention within a shorter time, resulting in improved hospital mortality.
