OBJECTIVETo describe our surgical experience on rupture of abdominal aortic aneurysm.

METHODSTwo cases of ruptured aortic aneurysms with severe complication were analysed. Aorta reconstruction procedures were performed using bifurcated e-PTFE grafts during emergency operation. Diagnosis, preoperative resuscitation, emergency surgical intervention, and postoperative complications of these patients were summarized and discussed.

RESULTSRupture of aortic aneurysm in both patients presented as a huge retroperitoneum haematoma by computed tomography scan. They were successfully saved by prompt body fluid compensation, emergency procedure, intraoperative resuscitation, and postoperative intensive care.

CONCLUSIONSCorrect diagnosis, prompt surgical management, immediate intraoperative proximal aorta clamping during procedure, and effective management of postoperative complications were the key points to successful treatment of ruptured aortic aneurysm.

BACKGROUNDAlthough it is generally acknowledged that patients with ruptured abdominal aortic aneurysm (rAAA) obtain the greatest benefit from endovascular repair (EVAR), convincing evidence on the medium-long term effect is lacking. The aim of this study was to compare and summarize published results of rAAA that underwent EVAR with open surgical repair (OSR).

METHODSA search of publicly published literature was performed. Based on an inclusion and exclusion criteria, a systematic meta-analysis was undertaken to compare patient characteristics, complications, short term mortality and medium-long term outcomes. A random-effects model was used to pool the data and calculate pooled odds ratios and weighted mean differences. A quantitative method was used to analyze the differences between these two methods.

RESULTSA search of the published literature showed that fourteen English language papers comprising totally 1213 patients with rAAA (435 EVAR and 778 OSR) would be suitable for this study. Furthermore, 13 Chinese studies were included, including 267 patients with rAAA totally, among which 238 patients received operation. The endovascular method was associated with more respiratory diseases before treatment (OR = 1.81, P = 0.01), while there are more patients with hemodynamic instability before treatment in OSR group (OR = 1.53, P = 0.031). Mean blood transfusion was 1328 ml for EVAR and 2809 ml for OSR (weighted mean difference (WMD) 1500 ml, P = 0.014). The endovascular method was associated with a shorter stay in intensive care (WMD 2.34 days, P < 0.001) and a shorter total postoperative stay (WMD 6.27 days, P < 0.001). The pooled post-operative complication rate of respiratory system and visceral ischemia seldom occurred in the EVAR group (OR = 0.48, P < 0.001 and OR = 0.28, P = 0.043, respectively). The pooled 30-day mortality was 25.7% for EVAR and 39.6% for OSR, and the odds ratio was 0.53 (95% confidence interval (CI) 0.41-0.70, P < 0.001). There was not, however, any significant reduction in the medium-long all-cause mortality rate (HR = 1.13, P = 0.381) and re-intervention rate (OR = 2.19, P = 0.243) following EVAR. In EVAR group, nevertheless, incidence of type I endoleak was significantly lower than type II endoleak (OR = 0.33, P = 0.039) at late follow-up period.

CONCLUSIONSOn the basis of this systematic review, rAAA EVAR results in less blood use for transfusion, shorter operation time, shorter intensive care unit and hospital stays, and lower 30-day mortality. However, in the medium-long term, it is not associated with a reduction in all-cause mortality.

OBJECTIVETo evaluate and report surgical management and experience of atypical ruptured abdominal aortic aneurysm (RAAA).

METHODSClinical data of 52 RAAA patients from May 2002 to February 2015 were retrospectively collected and analyzed. Thirty-three cases were included into this study based on atypical clinical presentation and etiology, including 6 infected RAAA, 5 inflammatory RAAA, 1 traumatic aortic rupture, 6 tuberculotic RAAA, 2 aoritc-vena cava fistula, 3 intestinal fistula and 5 spine erosion cases. Two of them refused operation during preparation, 19 of them received emergency open repair and 13 of them received endovascular aortic repair (EVAR) with 1 case converted to open surgery.

RESULTSThe systolic blood pressure of atypical RAAA before operation was (88±16) mmHg (1 mmHg=0.133 kPa), duration time from admission to diagnosis making was (17±10) hours. Perioperative death occurred in 1 patient because of hemorrhagic shock induced acidosis. During follow-up for 3 to 72 months, no operation related complications occured, such as artificial graft infection.

CONCLUSIONSEmergent operation including open surgery and EVAR is crucial for RAAA treatment. Early diagnosis, excellent operative techniques and comprehensive perioperative management are measures conducive to reduce the mortality rate of RAAA.

The rupture of an acute dissection of the ascending aorta into the space surrounding the pulmonary artery is an uncommon occurrence. No previous cases of transient pulmonary hypertension caused by a hematoma surrounding the pulmonary artery have been documented in the literature. Herein, we report a case of acute aortic dissection presenting as secondary pulmonary hypertension.

BACKGROUND: Endovascular aortic aneurysm repair (EVAR) has come into use and been widely extended because of the low complication rate and less-invasiveness. This article aimed to describe our experience in the treatment of abdominal aortic aneurysm with EVAR. MATERIALS AND METHODS: A retrospective review was conducted for the 22 patients who underwent EVAR in a single hospital December 2001 to June 2009. RESULTS: The mean age of the patients was 68.5+/-7.6 years. There were several risk factors and comorbidities in 20 patients (90.9%). The mean diameter of the aortic aneurysms was 61.2+/-12.9 mm. The mean length, diameter, and angle of the aneurysmal neck were 30.5+/-15.5 mm, 24.0+/-4.5 mm, and 43.9+/-16.0degrees, respectively. The mean follow-up period of the patients was 28.8+/-29.5 months. The 30-day postoperative mortality was none. Seven patients (31.8%) had endoleaks during the hospital stay and three patients (13.6%) had endoleaks during the follow-up period. One patient (4.5%) died due to a ruptured aortic aneurysm. The cumulative patient survival rates were 88.2%, 88.2%, and 70.6% at 1, 3, and 5 years of follow-up, respectively. CONCLUSION: EVAR is currently a safe, feasible procedure for high risk patients with abdominal aortic aneurysm because of low postoperative complication and mortality if patients are selected properly and followed up carefully.

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.
