Hemorrhagic pseudocyst and pseudocyst with pseudoaneurysm successfully treated by pancreatectomy: report of three cases

Hemorrhagic pseudoaneurysm of pancreatic pseudocyst is one of the serious complications of acute pancreatitis. We successfully treated three patients who had hemorrhagic pseudocyst and pseudocyst with pseudoaneurysm by pancreatectomy. Case 1 was 43-year-old Japanese man who had had several episodes of acute pancreatitis and was diagnosed with hemorrhagic pseudoaneurysm of the splenic artery in a pseudocyst in the pancreatic tail, shown on computed tomography (CT) and angiography. Transarterial embolization (TAE) yielded hemostasis of the pseudoaneurysm, but rebleeding occurred 2 weeks after the TAE. Distal pancreatectomy and splenectomy was successfully performed. Case 2 was a 64-year-old Japanese man who presented to us with several attacks of acute pancreatitis. Imagings showed bleeding pseudoaneurysm of the transverse pancreatic artery in a pseudocyst in the pancreatic body. Because of marked stenosis in the proximal portion of the transverse pancreatic artery, TAE was unsuccessful. Distal pancreatectomy and splenectomy was performed successfully. Case 3 was a 40-year-old Japanese woman who had a history of abdominal trauma. Imagings showed bleeding pseudoaneurysm of the splenic artery in a posttraumatic pseudocyst in the pancreas. TAE of the pseudoaneurysm was unsuccessful because of the proximity of the pseudoaneurysm and the splenic artery. Distal pancreatectomy and splenectomy was successfully performed and her postoperative outcome was satisfactory. Whenever interventional radiology (IVR) is not indicated or has failed, aggressive and immediate surgical intervention should be considered for early and definitive recovery in these patients.

Right atrial separation effect for chronic atrial fibrillation with atrial septal defect: report of four cases.

We operated on 56 adults diagnosed with atrial septal defect (ASD) between 1990 and 2004. Of these, eight had complications of atrial fibrillation (AF) in the preoperative period. After 1998, right atrial separation was performed in four cases. Marked improvement was noted in three out of the four cases. The right atrial separation procedure was a simple, easy, and effective method for the treatment of chronic AF associated with ASD.     

微创心脏不停跳下房间隔缺损修补术（附46例报告）

目的报告经右侧腋下小切口，在心脏不停跳下修补房间隔缺损的手术方法及结果。方法1997年1月至2000年3月，为46例房间隔缺损经右侧腋下小切口，在心脏不停跳下完成了缺损修补术，其中1例功能性单心房，2例部分型肺静脉(右侧)畸形引流，3例中度肺动脉高压。结果平均切口长度(7.2±1.1)cm。平均体外循环时间(30.3±7.8)分钟。术后所有患者无房水平分流及手术相关并发症，37例随访3月～2.4(1.3±0.6)年。所有患者心功能良好，无并发症。结论右侧腋下小切口心脏不停跳下房间隔缺损修补术，是一种安全、可靠、美观、微创的手术方法。     

右径小切口房间隔缺损封堵术21例临床分析

目的探讨右径小切口房间隔缺损封堵术的方法与疗效。方法回顾性分析我院2004年7月至2005年5月收治的21例房间隔缺损患者,男性8例,女性13例,年龄1～70岁,中位年龄21岁。房间隔缺损直径8～40mm。全麻下右胸骨旁第4肋间行2～3cm切口,在经食管或胸壁超声引导下,经右心房通过单鞘管置入房间隔缺损封堵器。结果全组21例无手术死亡,使用的封堵器型号为14～46mm,均封堵满意,无残余分流,未影响心脏瓣膜功能。无封堵失败改行体外循环手术者。术中未输血,术后未发生封堵器移位或脱落等严重并发症,术后3～5d出院。复查无残余分流,无严重并发症,效果满意。结论右径小切口封堵房间隔缺损安全、创伤小,有一定推广价值。     

The Waffle procedure for constrictive epicarditis after direct closure of atrial septal defect; report of a case

A 20-year-old man was admitted with a diagnosis of constrictive pericarditis 6 months after direct closure of atrial septal defect (ASD). He complained of fatigue and dyspnea. Cardiac echo cardiography, computed tomography (CT), magnetic resonance imaging (MRI) and cardiac catheterization suggested pericardial and epicardial constriction. During the operation, the thickened pericardium was peeled off. Multiple longitudinal and transverse incisions were made in the thickened epicardium as reported by waffle. Postoperative hemodynamic state was improved. The cardiac index increased from 1.91 to 3.17 l/min/m2. The pulmonary capillary wedge pressure (PCWP) decreased from 26 to 14 mmHg, although dip and plateau pattern was maintained. The postoperative course was uneventful.     

Port-access heart surgery for the treatment of cor triatriatum with atrial septal defect: Report of a case

A 40-year-old woman was admitted because of progressive dyspnea on exertion. Magnetic resonance imaging revealed an atrial septal defect and an abnormal membranous structure separating the left atrium into proximal and distal chambers. Surgical correction was performed by a minimally invasive surgical approach, i.e., port-access heart surgery, under the diagnosis of cor triatriatum (subtype of Lucas Schmidt IIIA1 or IB1) complicated with atrial septal defect. The postoperative course was uneventful, and she was discharged 12 days after surgery. This case is the first report of a surgical correction for cor triatriatum using the port-access technique.     

Left main coronary trunk compression by dilated main pulmonary artery in atrial septal defect. Report of three cases.

Narrowing of the left main coronary trunk, which was compressed by the dilated pulmonary artery, was associated with atrial septal defect in three adults. One of them had severe pulmonary hypertension. Coronary angiograms revealed localized narrowing of the left main coronary trunk, and the left main coronary trunk had a concave shape. No stenosis of other coronary arteries was observed. In all patients the atrial septal defect was closed with a polytetrafluoroethylene patch. In the patient with 75% narrowing of the left main coronary trunk, aorta-coronary bypass was performed; it was not performed in the two with 50% narrowing. In two survivors postoperative coronary angiograms showed that the narrowing of the left main coronary trunk improved or disappeared. These results suggest that markedly dilated pulmonary arteries easily compress the left main coronary trunk and cause narrowing, which improves after atrial septal defect closure.     

A case of chronic constrictive pericarditis with rheumatic valvular heart disease successfully treated by surgery

Chronic constrictive pericarditis and rheumatic valvular heart disease are common surgical conditions, but the simultaneous occurrence of both is extremely rare and poses problems in diagnosis and treatment. A 47-year-old male with constrictive pericarditis and rheumatic valvular heart disease was successfully treated with operation. The valvular dysfunction had included aortic, mitral and tricuspid regurgitations. He had also complicated severe hepatic dysfunction due to the cardiac constriction and the secondary tricuspid valve regurgitation. With the aid of cardiopulmonary bypass radical pericardiectomy was performed for almost all cardiac surfaces including that of both ventricles, the right atrium, and the venae cavae. After the pericardiectomy, aortic valvular replacement, mitral and tricuspid valvular annuloplasties were performed. Postoperative course was uneventful and the hemodynamic abnormalities (elevated right atrial and ventricular end diastolic pressures) as well as the depressed hepatic functions were dramatically improved postoperatively.
