Pituitary apoplexy is a rare but potentially life-threatening clinical syndrome caused by the sudden enlargement of a pituitary adenoma secondary to hemorrhage or infarction. Pituitary apoplexy after cardiac surgery is a very rare perioperative complication. Factors associated with open heart surgery that may lead to pituitary apoplexy include hemodynamic instability during cardiopulmonary bypass and systemic heparinization. We report a case of pituitary apoplexy after mitral valvuloplasty with cardiopulmonary bypass. After early pituitary tumor resection and hormonal replacement therapy, the patient made a full recovery.

Aortic dissection is a challenging disease and the causes of that are well-known. Blunt chest trauma is one of the causes of aortic dissection. In such cases, nearly all cases involves the isthmic portion of descending aorta, but ascending aorta is involved in about 10. We experienced a patient who had ascending aortic dissection due to automobile accident and who showed spontaneous rupture of the aorta during operation. In this case, after installation of aortic line via left femoral artery, ascending aorta ruptured and a large amount of blood gushed out, which was suckered by cardiotomy sucker. A little delay of cardiopulmonary bypass may cause the fatal outcome in such a case because the bleeding from aorta is too much to be controlled. Fortunately, we controlled the bleeding with cardiopulmonary bypass and got the good outcome of this patient by interpositioning the vascular graft. One should suspect the possibility of aortic dissection in blunt chest trauma, and prepare all the facilities against bleeding due to rupture.

Patent ductus arteriosus in adult is frequently complicated with aneurysm, calcification and pulmonary hypertension. Therefore, surgical treatment of patent ductus arteriosus in adult has some differences from that of infants and children. We have experienced 25 cases of adult patent ductus arteriosus from July 1983 to December 1994. Mean age of the patients was 26.6 years[16-59 years . There were 12 males and 13 females. Exertional dyspnea was the most frequent clinical manifestation. Pulmonary hypertension was present in eight patients. Ligation was done in 20 cases and surgery using cardiopulmonary bypass was done in 5 cases. There was one hospital death, which had a 5x5cm sized main pulmonary artery aneurysm and was operated under cardiopulmonary bypass. Recanalization occured in one patient who received Teflon-felt supported ligation. Although one case of recannalization after ligation was present, we believed the fact that ligation was safe and simple method of operation in adult patent ductus arteriosus without calcification and aneurysm.

Communications of coronary arteries with the cardiac cavities have first time been described by Krause in 1865 in a case of an accessory artery draining into the pulmonary artery and later Cayla in a case of a right coronary artery entering the right ventricle. The initial cases have been found accidentally at autopsies, however In recent years after the Introduction of angiography and coronary arteriography, the malformation Is diagnosed during life and is corrected surgically. These conditions are unusual entitles since the advent of angiography they are being diagnosed with increasing frequency. Three patients who had surgical correction of coronary-cardiac chamber fistula at our hospital are presented. In the first case and second case, coronary arteriovenous fistula was corrected horizontal mattress suture ligation with pladget under the cardiopulmonary bypass and third case was corrected double ligation with cardiopulmonary bypass standby. The postoperative courses were uneventful. They discharged without any fistula related complica-tions.

This is a report of a case in which a left atrial myxoma was successfully removed by total cardiopulmonary bypass with total hemodilution and moderate hypothermia. The patient was a 17 old girl with mitral valvular symptoms that occured suddenly three months prior to operation. After the onset of symptoms. it was progressively aggravated to serious general condition. The preoperative diagnosis of left atrial tumor was made from echocardiography. and the tumor was confirmed as myxoma by the histopathological examination of the tumor tissue removed during operation. The myxoma was unusually originated from posterior wall of the left atrium. which was located between drainage orifices of right and left pulmonary veins, The tumor developed in the left atrial cavity and one of the polypoid processes of the myxoma was prolapsed into the the left ventricle through the mitral orifice. Following operation. there was no evidence for peripheral vascular embolism, and all valvular symptoms disappeared. The postoperative course was uneventful.

A experimental study of deep hypothermia for open heart surgery in 5 dogs was reviewed. Surface hypothermia in combination with limited cardiopulmonary bypass was employed. Circulatory dynamics were well maintained following cardiac arrest during one hour at $20^{\circ}C$. Some degree of acidosis usually developed after the arrest period but was gradually corrected during. rewarming Total circulatory occlusion could be maintained for at least one hour at $20^{\circ}C$ without evidence of cerebral damage in the dogs. Potassium in the serum after deep hypothermia was moderately decreased and it was the most severe change in the electrolyte. Free hemoglobin of serum was mild increased and it was one of advantages of combined hypothermia with limited cardiopulmonary bypass.

Plasma protein concentration, plasma albumin concentration, hematocrit, and arterial blood gas tension were measured in 15 mongrel dogs undergoing heart transplantation with cardiopulmonary bypass. The hemodilution due to priming solution resulted in a 49% decrease in plasma protein concentration, a 57% decrease in plasma albumin concentration, a 46%a decrease in hematocrit. The measurements had returned to preperfusion values 1 hour after the end of cardiopulmonary bypass. The intraoperative changes in plasma protein and albumin concentration did not correlate with changes in alveolar-arterial oxygen tension gradients[D[A\ulcorner PO2]]. It is concluded that, in the absence of an increase in left atrial pressure, marked decrease in plasma protein concentration can be tolerated without the occurrence of pulmonary edema. And further study should be done to determine how to prepare an ideal priming solution.

체외순환 후 heparin의 항응고효과를 중화시키기 위해 널리 사용되는 protamine에 대한 아나필락시스 반응은 매우 드물다. 하지만 그 결과는 매우 치명적일 수 있으며, 아직도 정확한 발생기전이 알려져 있지 않다. 당뇨병이 없는 57세 여자 환자가 승모판막 치환술 및 극초단파(Microwave)를 이용한 Maze 술식을 시행 받은 후 protamine에 의한 심각한 아나필락시스 반응이 발생하여 증례 보고하는 바이다.

Successful emergency pulmonary embolectomy with the cardiopulmonary bypass was performed in a 41 \ulcorneryear old male who suffered massive pulmonary embolism after longterm bed rest due to the injury of left knee. Temporary cardiopulmonary bypass provided 120 minutes of circulatory support while complete removal of bilateral pulmonary emboli accomplished using Forgarty catheter and Gall stone forceps. Also, manual compression of the lungs was necessary to remove distal branching emboli. The patient had smooth and uneventful hospital course without complications and discharged from hospital taking coumadine on the 13th day after the operation.
