[Intrascrotal sclerosing lipogranuloma: a case report].

The etiology of granuloma of the male genitalia has been a controversial issue. Paraffinoma resulting from local injection of paraffin hydrocarbon is a well established entity. Granuloma lacking the evidence of exogenous oil, however, is in enigma. Only 9 cases in which no causative agents were identified, have been reported in the Japanese literature. Herein we report a case of sclerosing lipogranuloma laying emphasis on the necessity of being aware of the entity which should lead to its proper diagnosis and treatment.

[Removal of intra-atrial tumor thrombus of renal cell carcinoma: report of a case].

A case of left renal cell carcinoma with a tumor thrombus extending into the vena cava and the right atrium is reported. A 49-year-old female presented with a one month history of palpitation, dyspnea, and leg edema. CT-scanning and angiography revealed a left renal tumor with a tumor thrombus extending into the right atrium. Left nephrectomy and the removal of an intra-atrial tumor thrombus were performed under cardiopulmonary bypass. The postoperative course was unfavorable and the patient died on the 42nd day after the operation because of multiple organ failure in spite of repeated hemoperfusion. Operative procedure and prognosis of renal cell carcinoma with tumor thrombus extending into the right atrium are discussed.

Changes in myocardial oxygen consumption and coronary sinus blood flow before and after resection of left ventricular aneurysm after myocardial infarction.

The patients in this study consisted of eight men who underwent resection of left ventricular aneurysm. Right and left heart catheterization at rest and measurement of coronary sinus blood flow by continuous thermodilution were performed preoperatively and an average of 6 months after the operation. Coronary sinus blood flow decreased significantly from 161 to 118 ml/min and myocardial oxygen consumption decreased significantly from 17.2 to 10.5 ml/min postoperatively. Cardiac index increased postoperatively. Ejection fraction increased from 0.31 to 0.49 and mean velocity of circumferential fiber shortening significantly increased from 0.53 to 1.0 circ/sec postoperatively. Left ventricular end-diastolic volume decreased significantly from 166 to 120 ml/m2 postoperatively. The mean systolic circumferential tension significantly decreased postoperatively. We believe that the decrease in wall tension postoperatively brought about the reduction in myocardial oxygen consumption. Thus the high wall tension and myocardial oxygen demand, present preoperatively, were improved postoperatively, with a resultant lowering of oxygen consumption and equivalent or better left ventricular function.
