[Osmolar and free water clearance as renal function test during extracorporeal circulation with parcial and total hemodilution (author's transl)].

Four groups of dogs are subjected to extracorporeal circulation. Total hemodilution is used in groups I and II, either in normothermia or moderate hypothermia at 30 degrees C. Partial hemodilution is used in groups III and IV with identical temperature variations. The animals are kept under extracorporeal circulation for 120 min. Osmolar and free water clearance are measured at basal conditions after 40, 80 and 120 min. The present results show that total hemodilution should be used in those patients subjected to extracorporeal circulation where renal function has been previously disturbed.

Cardiac echinococcosis: report of 3 cases and review of the literature.

Three patients who underwent successful surgical treatment of cardiac hydatid disease are discussed. The nonspecificity of diagnostic measures and the importance of keeping this diagnosis in mind when faced with a patient coming from an area where hydatidosis is endemic are stressed. We propose the use of cardiopulmonary bypass in the surgical treatment of this problem.

Budd-Chiari syndrome due to obstruction of the inferior vena cava. A report of two cases.

Two cases of Budd-Chiari syndrome caused by membranous occlusion of the proximal portion of the inferior vena cava are presented. Both were treated surgically, using the modified technique of Kimura in one case, and a resection with direct vision and extracorporeal circulation in the other. Both patients progressed well. We discuss the etiology and pathogenesis of the syndrome, the diagnostic means that can be used, and the importance of early treatment.

Combined mitral and aortic valve replacement with the Börk-Shiley prosthesis.

Combined mitral and aortic valve replacement with the BJORK-Shiley tilting-disc valve prosthesis was performed in 42 patients. Hospital and late mortality rates were both at the 9.5% level. No correlation was seen between mortality and combination of concomitant valve lesions. Morbidity was elevated. No episodes of embolism were observed after surgery, although one patient died of severe haemorrhage. Only one patient showed valvular dysfunction (grade 2/4 leakage), but did not require reoperation. Postoperatively, 75.7% of the patients were asymptomatic for a mean follow-up period of 21.1 months. The Björk-Shiley prosthesis offers a small gradient associated with a low profile, which constitute important advantages in multiple valve replacement.

Supravalvular stenotic mitral ring. A new case with surgical correction.

In this report, we present a case of supravalvular stenotic mitral ring in a child. The lesion created a picture of severe mitral stenosis and was successfully managed by resection of the ring. No other malformations of the mitral apparatus or left ventricular outlfow tract were found. On analyzing the diagnostic criteria, we concluded that there appears to be only one useful criterion--the angiographic morphology. However, when ther- is an associated ventricular septal defect or findings of Shone's complex, we should suspect supravalvular ring rather than any other form of mitral stenosis.

Pulmonary arteriovenous fistula. A review.

A successfully treated case of an arteriovenous fistula of the lung is reported. An exhaustive review is made of the pertinent literature and the pathophysiology, embryology, clinical aspects, diagnosis and treatment are discussed.

Anoxic cardiac arrest: Its effect on myocardial mitochondrial metabolism.

Forty eight healthy dogs are subjects to cardiopulmonary bypass and divide into two groups according to whether the perfusion is performed in normothermia or moderate hypothermia (30 degrees C). The effects on oxidative phosphorylation and mitochondrial respiration, produced by increasing periods of myocardial anoxia from aortic cross clamping, are studied. A clear correlation is found between the disturbances of mitochondrial metabolism and the future cardiac recovery. Hypothermia shows a protective effect on the anoxic myocardium. It is concluded that the period of absolute safety in cardiac anoxia, as far as mitochondrial function is concerned, is 15 minutes in normal thermic perfusion and 90 minutes in moderately hypothermic ones.
