Thoracoabdominal aortic aneurysm (TAAA) involving the roots of the celiac, superior mesenteric and both renal arteries is a rare, but potentially lethal disease. The overall postoperative mortality rate is high even when the intact TAAA is electively repaired. Furthermore, the postoperative complications are often serious and they include acute renal failure, paraplegia, respiratory distress and intestinal ischemia. The inclusion technique using a visceral-aortic patch (VAP) is considered the gold standard method for visceral artery revascularization for the treatment of TAAA. However, the inclusion technique is not feasible for patients with Marfan syndrome or for those patients with inappropriate anatomy for VAP. In such cases, separate visceral revascularization is a useful alternative and this may decrease the visceral ischemic time. Herein we report on 3 cases of TAAA, and the patients all underwent successful separate visceral revascularization, including one patient with Marfan syndrome.

Acute coronary artery obstruction is a rare but fatal complication of surgical aortic valve replacement (AVR). Sudden coronary spasm, embolization of calcium plaque, and surgical factors can induce acute coronary syndrome after AVR. Here, we report a case of left main coronary ostial obstruction that occurred immediately after weaning from cardiopulmonary bypass. This case highlights the importance of coronary ostial flow patency and assessment of regional wall motion abnormalities with intraoperative transesophageal echocardiography in AVR.

Objective: To investigate the influence of blood pressure control after discharge on prognosis of patients with acute aortic syndrome (AAS) complicated with hypertension who underwent thoracic endovascular aortic repair (TEVAR). Methods: This is a retrospective case analysis. Patients diagnosed with AAS complicated with hypertension and undergoing TEVAR in Northern Theater Command General Hospital from June 2002 to December 2021 were consecutively enrolled. Average systolic blood pressure (SBP) and the occurrence of endpoint events were recorded at one month, one year and every 2 years after TEVAR. According to the patients' average SBP, patients with average SBP<140 mmHg (1 mmHg=0.133 kPa) or<150 mmHg were divided into the target blood pressure achievement group, and the others were divided into target blood pressure non-achievement group. Endpoint events included all-cause death, aortic death, stroke, renal insufficiency, aortic related adverse events and a composite of these events (overall clinical adverse events), and re-accepting TEVAR. The incidence of endpoint events was compared between the two groups at each follow-up period. Results: A total of 987 patients were included, aged (55.7±11.7) years, including 779 male (78.9%). When the cutoff value was 140 mmHg, the rate of average target SBP achievement was 71.2% (703/987) at one month, 66.7% (618/927) during 1st to 12th month and 65.1% (542/832) from the first year to the third year after TEVAR. The proportion of patients taking≥2 antihypertensive agents was higher in the group of target blood pressure non-achievement group than the target blood pressure achievement group after TEVAR at 1 month (74.3% (211/284) vs.65.9% (463/703), P=0.010) and during 1st to 12th month (71.5% (221/309) vs. 63.6% (393/618), P=0.016). There were no statistical differences in the all-cause deaths, stroke, aortic related adverse events, and repeat TEVAR between the two groups (All P>0.05) during above follow-up periods. When the cutoff value was 150 mmHg, the rate of target SBP achievement was 89.3% (881/987) at one month, 85.2% (790/927) during 1st to 12th month and 85.6%(712/832) from the first year to the third year after TEVAR. The incidence of clinical total adverse events (8.8% (12/137) vs. 4.2% (33/790), P=0.021) and repeat TEVAR (4.4% (6/137) vs. 1.0% (8/790), P=0.003) in target blood pressure non-achievement group were significantly higher than the target blood pressure achievement group during 1st to 12th month after TEVAR. The incidence of all-cause deaths (5.8% (7/120) vs. 2.4% (17/712), P=0.037) in the target blood pressure non-achievement group was significantly higher than the target blood pressure achievement group from the first year to the third year follow-up period, but there were no statistical differences in the incidence of clinical total adverse events between the two group (P>0.05). Conclusion: Among TEVAR treated AAS patients complicated with hypertension, the average SBP more than 150 mmHg post discharge is associated with increased risk of adverse events. Ideal blood pressure control should be encouraged to improve the outcome of these patients.

The main cause of death in hemodialysis patients is cardiovascular disease. Aortic dissection with rupture is one of the most life threatening cardiovascular diseases. The risk of developing aortic dissection can be increased by renal failure or hemodialysis and the morbidity also increases in Turner syndrome. Here, we report a case of Turner syndrome patient who died from ruptured aortic dissection after hemodialysis, and review relevant literature. A 59 year-old female presented to the emergency department complaining of severe dyspnea and general weakness. Six months ago, she had undergone an operation at another hospital due to horseshoe kidney and staghorn calculus. After the operation, acute renal failure developed, so she received hemodialysis. The chest x-ray image taken at the time of admission showed mediastinal widening compared to image taken 6 months ago. Aortic dissection was diagnosed by chest computer tomograph. Chromosomal analysis was performed and the study revealed the mosaicism of Turner syndrome (45,X/ 46,XX). The genetic defect, renal failure and especially hemodialysis were thought as important risk factors in the development of aortic dissection in this patient. Although storongly advised to have emergency operation, the patient only wanted conservative management. Two months later, the patient died from aorta rupture.

PURPOSE: Acute myocardial infarction (AMI) concomitant with acute aortic syndrome (AAS) is rare but prompt recognition of concomitant AAS is critical, particularly in patients with ST-segment elevation myocardial infarction (STEMI) because misdiagnosis with early thrombolytic or anticoagulant treatment may result in catastrophic consequences. This study examined the clinical features of patients of STEMI concomitant with AAS that may be a diagnostic clue. METHODS: Between January 1, 2010 and December 31, 2014, 22 patients who had the initial diagnosis of acute coronary syndrome (AMI and unstable angina) and AAS (aortic dissection, intramural hematoma, and ruptured thoracic aneurysm) in our emergency department were reviewed. Among them, 10 patients who were transferred from other hospitals and 4 patients with non-STEMI were excluded, leaving 8 patients of STEMI concomitant with AAS for analysis. RESULTS: The mean age of study patients was 57.5+/-16.31 years and five patients were Stanford type A and three patients were type B aortic dissection. Six patients had ST-segment elevation in anterior leads and 2 patients in inferior leads. Most patients had acute onset and severe chest pain, but none had dissecting nature chest pain. Serum troponin I was elevated in three patients but all patients had Ddimer elevation. Aortic regurgitation or regional wall motion abnormality was detected in four patients, and widened mediastinum was observed in all study patients. CONCLUSION: Concomitant AAS might be suspected in patients with STEMI who have elevated D-dimer and widened mediastinum.

OBJECTIVETo summarize the experience with emergency coronary artery bypass grafting (ECABG) for management of acute coronary syndrome and analyze the mid-term follow-up results.

METHODSForty-five ECABG surgeries were performed in 34 male and 11 female patients (aged 65.6∓5.8 years) for cardiogenic shock (5 cases), acute heart failure (6 cases) and refractory unstable angina (34 cases). Twenty patients received the operation within one week after acute myocardial infarction (AMI) and 18 were preoperatively supported by intra-aortic balloon pumping (IABP). All patients had triple-vessel disease and 15 had left main stenosis. Ten patients experienced two myocardial infarctions and 6 had chronic renal dysfunction including two requiring hemodialysis. On-pump operations were performed in all cases with a mean CPB time of 104.2∓29.7 min and cross clamping time of 69.0∓21.3 min. Cold blood or HTK cardioplegia was used for myocardial protection. The left internal mammary artery (LIMA) was routinely anastomosed to the left anterior descending artery (LAD), and the great saphenous vein (GSV) to other target vessels. The mean number of grafts was 2.9∓0.6.

RESULTSForty-one patients were cured and discharged and 4 patients died with an in-hospital mortality of 8.9%, including one associated with cardiac event (2.2%). IABP was weaned off within 28.5∓10.6 h after surgery except for one patient who died of multiple organ and system failure (MOSF). Thirty-eight patients (92.7%) were followed up for a mean of 37.3∓16.7 months, during which 2 patients died with a mid-term survival rate of 94.7%. Thirty-five (92.1%) patients had New York Heart Association (NYHA) class I and II. The freedom from cardiac event was 90.5%. Follow-up echocardiography showed significantly improved left ventricular dimension and ejection fraction in these cases (P<0.05), and graft patency was 95.8% for the LIMA and 90.5% for the GSV.

CONCLUSIONDespite a slight increase of the in-hospital mortality, ECABG can improve the mid-term survival, freedom from cardiac event, and cardiac function when the indications and timing for surgery are well controlled with optimal perioperative management.

Aortic aneurysm has poor prognosis and high mortality, but the incidence of aortic aneurysm is in increasing state. From July, 1986 to July, 1996, we operated on 25 patients with aortic aneurysm and analysed the clinical results and relations between the duration from symptoms onset to operation (Sx-Op), the duration from admission to operation (Adm-Op), preoperative blood pressure, preoperative heart rate and postoperative mortality, retrospectively. The patients were classified as dissecting aneurysm (10 cases), abdominal aortic aneurysm (9 cases), Marfan's syndrome (3 cases), descending thoracic aortic aneurysm (3 cases). The operative technique were graft interposition in 17 cases, Bentall's operation in 4 cases, aneurysm bypass in 2 cases, and wrapping of aorta in 2 cases. Seven patients died of several causes, bleeding in 5 cases, acute renal failure in 1 case and respiratory failure in another one case. Before 1992, the early stage of operation, 6 mortality among 14 operated patients occurred, and after then 1 mortality among 11 operated patients occurred. Eighteen survivors were followed up from 1 to 118 months (mean 50.6 months), and total follow up was 911 patient-months. During the follow up period one patient died of melena 30 months after operation. The other patients did not complain chest pain or dyspnea. The surgical mortality was improved in the late period, and the major cause of death was intraoperative or postoperative bleeding. The Sx-Op duration, the Adm-Op duration, preoperative blood pressure and preoperative heart rate were proven to have no statistical relations with postoperative mortality.
