ABSTRACT
A 72-year-old woman was admitted with a sensation of compression and shortness of breath. A mass was detected in the right atrium (RA) by transthoracic echocardiography. Preoperative chest computed tomography showed an RA tumor measuring 30×24 mm in the lateral wall. We performed resection under the cardiopulmonary bypass. Histopathological examination confirmed that this tumor was a lipoma.
ABSTRACT
We report an operative case of papillary muscle rupture after myocardial infarction with sustained ventricular tachycardia. A 56-year-old man referred to our emergency room in shock. Emergency CAG showed total occlusion of the left circumflex artery, in which we placed a metallic stent. Even after re-canalization of the coronary artery was achieved, circulation was unstable. IABP and PCPS were used to maintain the systemic circulation. Trans-esophageal echocardiography showed papillary muscle rupture and massive mitral regurgitation. Under total cardiopulmonary bypass and cardiac arrest, we performed mitral valve replacement with a 27mm SJM mechanical valve. PCPS was continued after surgical treatment because of pulmonary congestion. Since the patient's circulation and respiratory function improved, PCPS and IABP were removed on postoperative days 3 and 5. However, after removal of IABP, ventricular tachycardia appeared and IABP, PCPS were re-inserted. After adequate medication with Amiodarone and Carbedirol, ventricular tachycardia was controlled. PCPS and IABP were then removed uneventfully on postoperative days 14 and 19.
ABSTRACT
A 59-year-old man was admitted with sudden onset of back pain and abdominal discomfort. There was no history of pancreatitis, abdominal injury, or abdominal surgery. Enhanced abdominal computed tomography (CT) showed retroperitoneal hematoma behind the head of the pancreas, and emergency angiography demonstrated retroperitoneal bleeding due to rupture of a superior pancreaticoduodenal artery aneurysm. Embolization was tried unsuccessfully, because of difficulty in selective cannulation of the vessel feeding the aneurysm. Emergency laparotomy was performed. We inserted a finger behind the pancreas via the lateral side of the duodenum by Kocher's maneuver, then ligated the ruptured portion of the superior pancreaticoduodenal artery. We did not reconstruct the artery because blood supply to the peripheral tissue was good. The patient's postoperative course was uneventful, and he was discharged from the hospital in good condition 1 month after surgery. CT proved to be useful in revealing the voluminous retroperitoneal hematoma, and angiography proved to be necessary for the definitive diagnosis of pancreaticoduodenal artery aneurysm.
