A 38-year old man was admitted to our hospital due to a $5{\times}6cm$ sized pulsating mass in the right neck. He suffered from intermittent neck pain and hoarseness for two months due to the rapidly growing mass. The radiological examinations revealed an aneurysm of the right common carotid artery near the bifurcation, and it was compressing the internal and external carotid arteries. Endarterectomy of the right internal carotid artery, aneurysmectomy of the right common carotid artery and graft interposition were done, while the cerebral circulation was maintained by an internal shunt. Intraoperative injury to the nerve tissue around the aneurysm was avoided. He was discharged on the postoperative 7th day without any complications.

Posttraumatic psoudoaneurysrns of the subclavian artery are very rare. A 49-year-old woman who had been involved in a car accident ten years before presentation was initially diagnosed with a mediastinal tumor at a local clinic. Exploratory thoracotomy was performed for evaluation and treatment. During the operation, a hematoma was evacuated, and primary repair was undertaken to stop massive bleeding. Computed tomography angiography revealed a pseudoaneurysm of the left subclavian artery. The patient was treated with aneurysmectomy and end-to-end anastomosis. The postoperative course was uneventful.

A 72-year-old man with progressive, unexplained lower gastrointestinal bleeding presented to the emergency department with abdominal pain and shock. Computed tomography of the abdomen showed a fistula between a right common iliac artery aneurysm and the small intestine. Laparotomy demonstrated a saccular aneurysm of the common iliac artery with a fistulous communication to the terminal ileum. Aneurysmectomy, aortoiliac graft replacement and segmental ileocecal resection with end-to-side anastomosis were all successfully performed. For a patient having an arterioenteric fistula along with lower gastrointestinal bleeding, making an early diagnosis using computed tomography and then performing immediate surgery can be expected to save the patient's life.

Between January 1986 and August 1993, 11 patients underwent surgical repair of ventricular septal defect [VSD] complicated with myocardial infarction. The ages of patients were ranged from 22 years to 83 years with a mean of 64 years. There were 8 male and 3 female patients. The preoperative cineangiograms of all patients were reviewed to measure both ventricular function and to evaluate coronary artery disease. The mean time interval between occurance of VSD and operation was 13 days. The operations were performed as soon as possible if there were hemodynamic derangement. Postmyocardial infarction VSD were repaired simultaneuously with coronary artery bypass graft in 3 patients, repaired with left ventricular aneurysmectomy in 6 patients, with left ventricular thrombectomy in 1 patient and with mitral valve chordae repair in 1 patient. There was no early death [within 30 days]. There were 6 postoperative complications; one with perioperative myocardial infarction, two with recurred VSD on postoperative 1 and 6 days respectively, two with lower leg embolism associated with intraaortic balloon pump insertion, one with wound infection. Of the complicated patients, 1 patient with lower leg embolism performed left above ankle amputation. Among two patients with recurred ventricular septal defect, one patient is doing well without problem. On follow up echocardiogram, the residual VSD was occluded completely. However another patient was with recurred VSD died 3 months after the operation because of congestive heart failure. Of the long term survivors, all patients are in NEW YORK Heart Association functional Class I or II. Although number of patients were small, our results of surgical closure of postmyocardial infarction VSD were favored to the others. Moreover, seven patients with preoperative cardiogenic shock among 11 were performed early operation after diagnosis of ventricular septal rupture. All of the patients were survived and doing well during the follow up period. Therefore early diagnosis with aggressive preoperative care with intraaortic balloon pumping and early operation seems to be very important for prevention of deterioration of vital organ.

It was my great nohour that I can be exposed to such plenty materials of the coronary bypass surgery. Here, I am summarizing the xoronary bypass surgery, clinically. The material is serial 101 patients who underwent coronary bypass surgery between July 17, 1979 to November 30, 1979 in Shadyside Hospital, University of Pittsburgh. 1. Incidence of the Atherosclerosis is frequent in white, male, fiftieth who are living in industrialized country. It has been told the etiologic factor of the atherosclerosis is hereditary, hyperlipidemia, hypertension, smoking, drinking, diabetes, obesity, stress, etc. 2. The main and most frequent complication of the coronary atherosclerosis is angina pectoris. Angina pectoris is the chief cause of coronary bypass surgery and the other causes of coronary bypass surgery are obstruction of the left main coronary artery, unstable angina, papillary muscle disruption or malfunction and ventricular aneurysm complicated by coronary artery disease. 3. The preoperative clinical laboratory examination shows abnormal elevation of plasma lipid in 82 patint, plasma glucose in 40 patient, total CPK-MB in 24 patient stotal LDH in 22 patient out of 101 patient. 4. Abnormal ECG findings in preoperative examine were 29.1% myocardial infarction, 25.8% ischemia and injury, 14.6T conduction defect. 5. Also we had done Echocardiography, Tread Mill Test, Myocardial Scanning, Vectorcardiography and Lung function test to get adjunctive benefit in prediction of prognosis and accurate diagnosis. 6. The frequency of coronary atherosclerosis in main coronary arteries were LAD, RCA and Circumflex in that order. 7. The patients' main complaints which were became as etiologic factor undergoing coronary bypass surgery were angina, dyspnea, diaphoresis, dizziness, nausea and etc. 8. For the coronary bypass surgery, we used cardiopulmonary bypass machine, non-blood, diluting prime, cold cardioplegic solution and moderate cooling for the myocardial protection. 9. We got the grafted veins from Saphenous and Cephalic vein. Reversed and anastomosed between aorta and distal coronary A. using 5-0 and 7-0 prolene continuous suture. Occasionally we used internal mammary A. as an arterial blood source and anastomosed to the distal coronary A. and to side fashion. 10. The average cardiopulmonary bypass time for every graft was 43.9 min. and aortic clamp time was 23 minute. We could Rt. coronary A. bypass surgery only by stand by the cardiopulmonary machine and in the state of pumping heart. 11. Rates by the noumbers of graft were as follow : 21.8% single, 33.7% double, 26.7% triple, 13.9% quadruple, 3% quintuple and 1% was sixtuple graft. 12. combined procedures with coronary bypass surgery were 6% aneurysmectomy, 3% AVR, 1% MVR, 13% pacer implantation and 1% intraaortic ballon setting. 13. We could see the complete abolition of anginal pain after operation in 68% of patient, improvement 25.8%, no change in 3.1%, and there was unknown in 3%. 14. There were 4% immediate postoperative deaths, 13.5% some kinds of heart complication, 51.3% lung complications 33.3% pleural complications as prognosis.

Between May 1991 and September 1995, 7 patients underwent surgical repair of ventricular septal defect (VSD) complicated with myocardial infarction in Asan Medical Center. The patients included two male and five female. The ages of patients were ranged from 54 years to 76 years with a mean of 65 years. The sites of postinfarction ventricular septal defect were consist of anterior septal defect in 6 patients and anteroposterior septal defect in 1 patient. Preoperative 2D-echocardiography & angiography were performed in all patients in order to measure ventricular function and evaluate the extent of coronary artery disease. The operations were delayed till mean 24 $\pm$ 12days after myocardial infarction. All patients underwent infarctectomy and Teflon patch closures through the area of the left ventricle infarction or aneurysm in the anterior or apical aspect of postinfarction ventricular septal defect. The ventricular septal defect repaired simultaneously with coronary artery b pass graft in 3 patients, with ventricular aneurysmectomy in 5 patients, and with left ventricular thrombectomy in 1 patient. Patch fixation in the left side of interventricular septum by tracts-septal interrupted pledget suture reduced the recurrence rate of VSD. There were 2 postoperative complications : One with pneumonia, 1 patient with the skin necrosis of left thigh. There was ilo early death. The 6 patients except for one emigrant were followed up postoperatively between 3 and 63 months(mean .28 months), without any sequelae and late death. They are in New York Heart Association functional class I-II.

A 36 year old blindman, engineer was admitted with chief complaints of hemoptysis, recurrent sore throat, pyoderma in genital organ, uveitis and thrombophlebitis for 10 years. Above the chief complaints were remission or exacerbation during hospitalization. Physicalexamination showed that left radial, ulnar & brachial pulse was not palpable. No bruit or murmur was obtained over the mass. Neurologic examination revealed no significant finding.On admission, chest P-A showed hen egg sized round & oval compact hazy density on left upper lung field. Bronchogram revealed no pathological finding and Lt. tomogram showed well define large,ovoid mass density in the superior mediastinum. Fluoroscopy finding showed nonpulsatile on left upper lung field. Pre-op. aortography was not taken, under the impression of lung Ca. rule out .sortie aneurysm, exploratory operation was performed through the 2nd intercostal space, Lt. It was performed that the mass was ascending sortie aneurysm of saccular type. Direct aneurysmectomy with multiple figure of eight suture were done without any prosthetic graft. Post-op. control I.V.C graphy showed completely obstruction sign. Postopcontrol aortography revealed good surgical result. Final, histopathological answered non-specific sortie aneurysm, saccular type. Post-op. courses were uneventful except mild neurologic disturbance with subclavian steal syndrome and associated with both lower leg pitting edema due to inferior vena cava obstruction. After op, 3 month later, discharged to home, with big systemic problem. Behcet`s syndrome reviewed with related literatures. The coexistence of mouth and genital ulceration with hypopyon mentioned by hippocrates and described by various workers in the early part of this century was first defined as a syndrome by Behcet in 1937. In 1937 Behcet described a chronic relapsing triple symptom complex of oral ulceration, genital ulceration, and ocular inflammation. The place of the syndrome as part of a systemic disorder in now clearer, and the under lying pathology appears to be a vasculitis. The disease runs a- chronic course, blindness being the greatest disability and control nervous system involvement a cause of death. Thrombophlebitis is fairly frequent, france et al [1951] giving an incidence of 25% and Dowling [1961] 12%, superficial thrombophlebitis migrans and thrombosis of large veins, including venae cavae [Thomas, 1947: Boolukos 1960] are recorded. Little attention has been paid to arterial involvement. Mishima et al. [1961] described resection cf an aortic aneurysm in a 38 year old man with Behcet`s syndorme. Mounsey in a clinicopathological conference described a case [Brit, med. J., 1966] of ruptured aortic aneurysm in Bechcet`s syndrome treated by aorto-iliac graft. Also, Shikano and Oshima et al [1963] recorded two aneyrysm of smaller arteries. Unfrequently, aortic aneurysm was presumed to be secondary to osteomyelitis of the lumber spine, though the possible association between aortic aneurysm and Behcet`s syndrome was raised. A further case is reported here, in which ascending aortic aneurysm with Behcet`s Ds. appeared to form part of this generalized disease. This is a case report of surgical experience of Behcet`s Ds. with ascending aortic aneurysm which had nearly all the typical clinical features. Above mentioned and was reviewed with related literatures.

From March, 1983 to June, 1994, twenty-two patients underwent coronary artery and combined operations. The ages of the patients ranged from 42 years to 72 years (mean 60.4$\pm$8.2 years). There were 17 male and 5 female patients. The left ventricular (LV) ejection fraction ranged from 25% to 65% (mean 46.9$\pm$14.2%). Nine patients had mechanical complication of myocardial infarction (MI), of which 5 were LV aneurysm, 3 ventricular septal defect and 1 mitral regurgitation. Nine patients had rheumatic valvular heart disease of whom 7 with aortic valve disease and 2 with mitral valve disease. Two other patients had left atrial thrombi, only one with atrial septal defect a d another with aneurysm of ascending aorta. An average of 2.1$\pm$1.0 bypasses was done, ranging from one to four. There were 3 postoperative complications; 2 perioperative MI and 1 leg wound infection. Among complicated patients, mortality was 1 patient (4.5%) due to low cardiac output syndrome after perioperative MI. With 3 to 136 months follow-up (mean 41.1$\pm$40.2 months), late mortality was 1 patient due to cerebral vascular accident. Among long-term survivors, all patients are in New York Heart Association functional class I or II. Although the number of patients was small, our surgical results were favorable. Therefore we think that coronary revascularization combined with heart operation does not increase the operative risk when associated coronary artery disease is present, and it reduces the occurrence of late death.

From August 1986 until June 1995, single aortic valve replacement was performed in 65 patients at the Chonnam National University Hospital. worthy-eight were male and 17 were female patients, ranging from 19 to 68 years of age(median : 43 years). The causes of the valve lesions were rheumatic in 29 patients (44.6%), bicuspid aortic valve in 6 patients (6.2%), endocarditis in 6 patients(6.2%), unknown in others. Concomitant surgical procedures were performed in 10 patients : repair of congenital defect in 5, pericardiectomy in 1, coronary artery bypass grafting in 1, noncoronary sinus plication in 1, Valsalva sinus aneurysmectomy in 1, subaortic membrane resection in 1 Used valves were 51. Jude-Medical valve in 42, Duromedics valve in 22, Bjork-Shiley valve in 2, Carpentier-Edward valve in 1. There were 3 hospital deaths (4.6%), and 2 late deaths (3.2%). Follow-up was 95.2% complete. The 10-year acturlal survival rate was 85.3%. Postoperative complications were low cardiac utput in 8, arrythmia in 5, valve related hemolysis in 1, cerebral infarction in 1, and gastrointestinal bleeding in 2. Reoperation was performed in 4 for surgical bleeding, in 3 for paravalvular leak. The mean improvement in New York Heart Association functional class is from 2.79 $\pm$ 0.66 preoperatively to 1.25 $\pm$ 0.49 postoperatively(p < 0.001) The change of cardiothoracic ratio from preoperative to postoperative is 0.57 $\pm$ 0.06 to 0.54 $\pm$ 0.05 (p < 0.05). The left ventricular ejection fraction change is not significant perioperatively. There are no mechanical failures. This early and intermediate-term follow-up suggests that in adults in whom valve repair is not possible, the mechanical valve is a reliable and durable prosthesis with good hemodynamic function and a low rate of thromboembolic event.
