[A case of surgical treatment of Budd-Chiari syndrome].

A 37-year-old man was admitted to our hospital for evaluation and surgical treatment of Budd-Chiari syndrome. He underwent a radical operation (endovenectomy and patch dilatation) with femoro-femoral assist bypass. The inferior vena cava (IVC) showed narrowing just below the diaphragm, and its lumen was completely obliterated with fibrous tissue. The fibrous strand was partially resected, and the IVC was closed by Xeno-medica pericardial patch. The patient has been doing well after the operation.

Effect of temperature on the arrested heart exposed to a 4-hour ischemia during blood potassium cardioplegia. An experimental study.

This study was undertaken to evaluate the optimal myocardial temperature during a 4-hour ischemia induced by blood potassium cardioplegia (PC). Heart-lung preparations with work load circuit were used as experimental model. 24 mongrel dogs were divided into four groups and two myocardial temperatures (moderate hypothermia, deep hypothermia) and two perfusates (PC with blood, PC without blood) were tested. Parameters used to evaluate the myocardial protection include the coronary sinus blood pH of the initial reperfusion and left ventricular stroke work after resuscitation. In blood PC at moderate hypothermia, deleterious acid metabolites were minimally produced as evidenced by the coronary sinus blood pH (7.221 +/- 0.122) at initial reperfusion, and cardiac function was best recovered in this group. Blood PC at moderate hypothermia allows the heart to tolerate 4 h ischemia without an excessively elevated coronary perfusion pressure during cardioplegic infusion.
