  • The surgical treatment of annuloaortic ectasia falls into two basic categories, depending on the management of the coronary artery ostia and the sinus of Valsalva. The conventional method, first suggested by Groves, Wheat and their associates, employs a supracoronary graft for the treatment of aneurysm and conventional valve replacement. A more radical approach, that of Bentall and DeBono, uses a valve conduit from the aortic annulus to the distal extent of the aneurysm. This latter technique requires reimplantation of the coronary artery ostia for reestablishment of coronary artery blood flow. Recently we experienced a case of annuloaortic ectasia to which we applied the Bentall operation with the good postoperative result, and now we report this with literature review.

  • In the advanced age, cardiovascular disease is more serious than any other disease. Especially, the thrombus causes the serious disease like apoplexia, carebri and myocardial infarction. Thrombosis is caused by the injury of endothelium and the alterations in normal blood flow. To investigate activities of Carthamus tinctorius L. Semen butanol fraction for blood coagulation system, endotoxin (4000EU/kg) was injected (i..v) to rats at 1hr after administration of Carthamus tinctorius L. Semen butanole fraction (500 mg/kg, p.o.). Carthamus tinctorius L. Semen butanol fraction was found to have antiplatelet activity in vitro. In vivo it showed a delay of blood clotting time, and prothrombin time, and reduction of fibrinogen and FDP It also increased SOD activity, and decreased MDA content. These results suggest that the antithrombosis effect of Carthamus tinctorius L. Semen butanol frac tion results from suppressive activity for a blood coagulation system and antioxidative activity.

  • Mustard succeeded in the physiological correction of the circulation for transposition of the great arteries by redistribution of the pulmonary and systemic venous blood flow using pericardial baffle in the atrium. This procedure has become one of the most confirmative corrective operations for transposition. A six years old girl was performed mustard operation for complete transposition of the great arteries combined with hemodynamically insignificant ventricular septal defect in December 1979. The postoperative patient`s condition has been satisfactory and she is now enjoying a productive life.

  • Membranous obstruction of the inferior vena cava[IVC] is a rare congenital anomaly that may present clinical features of Budd-Chiari syndrome caused by chronic obstruction of hepatic drain. We have experienced a case of IVC obstruction caused by hour-glass constriction and membrane in its center. Operative correction was accomplished using profound hypothermia [20%] and total circulatory arrest of 26 minutes. This technique permitted resection of membrane with direct vision and removal of thrombus of IVC and hepatic vein. After then constricted IVC was repaired with autologous pericardial patch. Total circulatory arrest was used intermittently for good visual field. Postoperative course was smooth and postoperative angiography showed unobstructed flow through the IVC in spite of slight constriction of cavoatrial junction and nearly complete disappearance of collateral vessels.

  • Four patients with traumatic rupture of aorta underwent operative repair at Seoul national university hospital. All cases were confirmed by preoperative aortography. Rupture site was aortic isthmus or just distal to it. Operations were somewhat delayed due to the low degree of suspicion and difficulties in diagnosis: ranging from 5 hours to 8 days. Operation was performed as same manners in all cases: resection of the ruptured portion and tubular woven dacron graft interposition in conjunction with shunt or bypass procedures, TDMAC-Heparin shunt between ascending and descending aorta was used in 3 cases, and LA-femoral centrifugal pump was used in one case. There were no intraoperative or postoperative mortality. Hoarseness was developed in all patients but paraplegia or other significant complications were not found in any of patients. We concluded that 1] high degree of suspicion is essential in the early diagnosis and treatment of traumatic aortic rupture and 2] any kind of shunt or bypass procedure is necessary in operative repair of traumatic aortic rupture and use of centrifugal pump without systemic heparinization is easier and safer procedure than others for the maintenance of adequate distal flow.

  • The treatment of aortic aneurysm of ascending aorta has been fraught with difficult surgical problems. For the most part, these were resolved in 1968 with the introduction of a technique of total replacement of ascending aorta and reimplantation of the coronary arteries by Bentall and De Bono. This technique however, with all of its advantages, caries a certain problems. In chronic dissecting aneurysms, there is frequently a marked disparity in circumference between the true and false lumen distally. Distal perfusion is directed into both the true and false lumens by removing segment of the septum between the two lumens and constructing the distal graft anastomosis is to the outer layer of aortic adventitia. The distal false lumen, aortic branches and fenestrations have matured and healed in most cases. And importantly, major aortic tributaries may be solely dependent on the false lumen for perfusion. We are presenting two cases of chronic dissecting aneurysm of ascending aorta with aortic regurgitation, who have good result by surgical correction of so-called Bentall procedure with maintenance of blood flow directed into both true and false lumen.

  • Mixed Venous oxygenation saturation[SvO2 is a variable determined in part by the externally controlled factors and in part by the patient during CPB. I monitored the SvO2 and tested it as a parameter for the regulation of pump output and as a criteria for the need of inotropics after CPB. With the help of SvO2, I increased the pump flow especially during rewarming for more optimal oxygenation of cells. After CPB, the calculated cardiac index was used as an indicator for the need of inotropic support with greater accuracy and without any clinical problems. I conclude that the SvO2 is an easily checkable variable and a good indicator for optimal oxygenation at cell level, and can be used as an objective criteria for the need of postoperative inotropic support.

  • Pulseless electrical activity (PEA) is a clinical condition characterized by unresponsiveness and lack of palpable pulse in the presence of organized cardiac electrical activity and is caused by a profound cardiovascular insult (e.g., severe prolonged hypoxia or acidosis, extreme hypovolemia, or flow-restricting pulmonary embolus). Amyotrophic lateral sclerosis (ALS) is a disease that is characterized by progressive degeneration of all levels of the motor nervous system. Damage to the respiratory system and weakness of the muscles may increase the likelihood of an emergency situation occurring in patients with ALS while under general anesthesia. We report a case of PEA during the induction of general anesthesia in a patient with ALS who presented for dental treatment and discuss the causes of PEA and necessary considerations for general anesthesia in patients with ALS.

  • Total anomalous pulmonary venous return (TAPVR) is very rare congenital heart disease. 25-year old male was admitted our hospital with dyspnea, headache and syncope as chief complaint. He was confirmed as mixed type TAPVR by echocardiography and cardiac catheterization. In this case, mixed type TAPVR was consisted with supracardiac type connection of left pulmonary vein and cardiac type of right pulmonary vein. Supracardiac type of left pulmonary common channel was anastomosed to the left auricular appendage during total cardiopulmonary bypass with fibrillating heart. Cardiac type of right pulmonary vein was operated during moderate hypothermia and aortic cross clamping. Coronary sinus septum was incised into ASD and closed with Gore-Tex patch so that right pulmonary blood flow directed to the left atrium. The patient's post-operative course was uneventful.

  • Total atherosclerotic obstruction of the juxtarenal abdominal aorta is a relatively rarely encountered form of atherosclerotic vascsular disease, accounting for less than 5% of all arterial obstrutive disease. We have encountered two patients with such lesions, both of whom were admitted for intermittent claudication of the lower extremities and symptoms of vascular ischemia. Digital subtraction angiography[DSA] was performed on both patients, the results of which revealed total obstruction of the aorta just inferior to the renal arteries without involving the latter. Operative technique involved the use of the sup-raceliac aorta as the site of proximal anastomosis of aortofemoral bypass followed by a fem-orofemoral bypass graft with Smm sized Woven Dacron[Vascutek] through a subcutaneous tunnel within the retroperitoneal space. Both patients experienced restoration of blood flow distal to the obstruction postoperatively without any complications, and OPD follow-up one month postoperatively and postoperative DSA showed evidence of continued graft patency with persistent symptomatic improvement.
