In 1964, Abbott and Colleagues published the world's first heterotopic heart transplantation technique in the rat. Their method established circulation by end-to-end anastomoses of the graft's aorta and pulmonary artery to the recipient's abdominal aorta and Inferior Vena Cava(IVC), respectively. In 1966, Tomita et al altered Abbott's technique by employing end-to-side rather than end-to-end anastomoses, thus eliminating the hind leg paralysis that sometimes resulted from Abbott's technique. In order to prevent postsuture hemorrhage (since 7-0 silk suture was the finest available at that time), Tomita's aortic anastomosis was done with double up-and-down continuous suture technique. A single layer continuous anstomosis effected the pulmonary artery-IVC anastomosis. The availability of Nylon monofilament suture made it possible for Ono and Lindsey to use a single layer suture technique for the aortic end-to-side anastomosis in their modified rat heart transplantation. We observed survival time between control group and Immunosuppression(Cyclosporine administration, 10mg/Kg${\times}$4 times postoperatively) group after heterotopic heart transplantation in the rat model. The cyclosporine adminstration group survived longer than the control group, thus we concluded that cyclosporine was based on Immunosuppressive drugs.

A case is presented of a steering wheel Injury to the chest which developed right atrial free wall rupture and cardiac tamponade without rib fractures or hemo-pneumothorax. A 30 year old man who sustained, blunt chest trauma by steering wheel injury to his chest developed right atrial rupture and cardiac tamponade. Pericardiocentesis was performed and cardiac tamponade was confirmed. After a median sternotomy, large right atrial free wall laceration [about 8cm] was noted. He was placed on cardiopulmonary bypass. The laceration wound of right atrium was closed with a 2 rows of continuous suture. Recovery was uneventful. The patient has returned to his previous level of activity.

One case of surgical correction of a large aortopulmonary window in a 4 months old female is reported in detail. Clinical symptoms consisted of fatigue when feeding and recurrent upper respiratory tract infection. Under cardiopulmonary bypass with moderate hypothermia and cardioplegic arrest of the heart, the aortopulmonary window was approached through a vertical incision at the anterior wall of window itself. The defect was closed with pericardial patch using continuous suture posteriorly and sandwitch technique anteriorly. The patient was weaned from the cardiopulmoanry bypas without hemodynamic problem and postoperative course was uneventful. This surgical technique is recommandable as it provides good exposure of the defect and can be performed easily and safely.

Purpose : This study was undertaken to observe the occurrence of the vessel aneurysms according to several different methods of microvascular anastomosis. Mterials & methods : Forty Sprague-Dawley rats, weighing $180{\sim}200$ grams, were used for this experiment. The rats were divided into 4 groups. Group 1 (10 rats): The adventitia was trimmed off 5mm from the cut edge each and 20 arterial anastomoses were performed using 8 to 10 interrupted 9-0 polypropylene ($Prolene^{TM}$, Ethicon, U.K.) suture. Group 2 (10 rats): The adventitia was trimmed off as in group 1. Twenty arterial anastomoses were performed using continuous 9-0 polypropylene($Prolene^{TM}$, Ethicon, U.K.) suture. Group 3 (10 rats): The adventitia was stripped only 1mm from the cut edge each but not removed,. Twenty arterial anastomoses were performed using 8 to 10 interrupted 9-0 polypropylene($Prolene^{TM}$, Ethicon, U.K.) suture. Group 4 (10 rats): The adventitia was handled as in group 3. Twenty arterial anastomoses were performed using 9-0 polypropylene($Prolene^{TM}$, Ethicon, U.K.) suture. The arteries of the animals in all groups were explored at 28th days. We examined patency, presence of an aneurysm, other vascular abnormalities and microscopically observed the aneurysms with H&E and Van-Gieson stains. Result : 1. Patency rate was 80% in group 1, 95% in group 2, 85% in group 3 and 90% in group 4, respectively. 2. Aneurysm occurred 20% in group 1, 5% in group 2, 5% in group 3 and 5% in group 4, respectively. 3. There was no other vascular abnormalities in each group. 4. Infection rate was 5% in group 1, 0% in group 2, 20% in group 3 and 15% in group 4, respectively. 5. In the histopathological findings, we observed partially necrotic changes, loss and fragmentation of outer elastic lamella of smooth muscle in media and the proliferation of hyperplastic subintima. A lot of inflammatory cells were infiltrated in hyperplastic intima. Conclusions : On the basis of these observation, we could state that there were little differences in the occurrence of aneurysms according to different anastomotic suture methods.

Coronary arteriovenous fistula is a relatively rare congenital heart disease and it drains into right atrium, right ventricle, pulmonary artery, coronary sinus or superior vena cava. We experienced one case of fistulous communication between right coronary artery and right ventricle which was most common condition. The patient was a 12 year old female and the only sign was continuous cardiac murmur. The cardiac catheterization and coronary angiography showed the fistulous communication between right coronary artery and right ventricle and aneurysmal dilatation of right coronary artery. Under the cardiopulmonary bypass with the hypothermic cardioplegia, fistula opening[7mm] which was located at right ventricle below the tricuspid valve annulus between septal and posterior leaflet was closed with 4 - 0 prolene continuous suture through right ventriculotomy. Her postoperative course was uneventful.

Purpose: Except for continuous suture in skin layer, stitching out in facial laceration, we have to hold each knots up and cut the knots by No. 11 blade or small scissors. However, we often have difficulty in stitching out the knots on children who do not cooperate well. Therefore we introduce an easy and fast stitch out method of pediatric lacerations. Methods: From January to May 2009, we studied 15 pediatric patients (mean age 5.6 years old) who had facial laceration on face or underwent any surgery on operation room. For easy stitch out, we left the one string of the first knot long enough to extend at the opposite end of laceration site. And then the extended string was fixed to skin using Steri-strip. Next we do simple interrupted suture including the extended traction nylon string inside the knot. Through this method, we can stitch out all knots simply by lifting up the traction nylon needless to hold the each knot one by one. Results: Until stitching out, the traction nylon was just right position and there was no normal tissue injury during stitch out all knots. Patients were satisfied with the short stitch out time. Conclusion: By using the traction nylon on pediatric laceration suture, we can stitch out all the knots with no normal tissue injury in less time.

Surgical treatment for PDA has been pivotal in historical development of surgery for congenital heart disease. A clinical study on 36 cases of operated PDA were performed during period from Aug. 1981 to Jul. 1985 at the Department of Thoracic & Cardiovascular Surgery in Chonbuk University. The following results are obtained. 1. The 8 males and 28 females ranged in age from 2 yrs, to 24 yrs, [mean 11 yrs.] 2. Chief complaints of the patients were dyspnea on exertion in 61%, palpitation in 39%, frequent URI in 12%, and no subjective symptoms in 11%. 3. On auscultation, continuous machinery murmur heard in 94% and systolic in 14%. 4. Radiologic findings of chest P-A showed increased density of pulmonary vascularity in 94%, cardiomegaly in 69%, and within normal limits in 5% of the patients. 5. EKG findings of the patients revealed LVH in 69%, RVH in 6%, BVH in 6%, and within normal limits in 17%. 6. Of the 36 patients, cardiac catheterization was performed in 34 patients. The results showed mean Qp/Qs = 2.25, mean Pp/Ps=0.42, and mean systolic pulmonary arterial pressure=53mmHg. 7. Surgical methods were as followed: The 32 case of ductal ligation and one case of division & suture technique for PDA through the left posterolateral thoracotomy were done. And 2 cases of ductal ligation one suture closure through the pulmonary artery were performed under the cardiopulmonary bypass. 8. Intraoperative complication was ductal rupture with division 8< suture for PDA and transient hoarseness in 1, recanalization in 1, and urethral stricture in 1 case postoperatively. 9. One patient died due to ductal rupture intraoperatively and operative mortality was 2.8%.

Sixteen clinically healthy New Zealand white rabbits of either sex were divided into two equal groups I and II of 8 animals each. Under thiopental sodium (2.5%) anaesthesia a linear full thickness abdominal wall defect of 3 cm in length was created and repaired with continuous suture pattern using 3000 filaments of carbon fibres and 1~0 black braided nylon suture, ingroup I and II respectively. Increased vascularity was observed in carbon fibres (group I) and on day 30 the carbon fibres were covered by white fibrous tissue. Significantly higher (P < 0.05) values of glucose was seen on day 14 in group I, whereas, decrease in glucose value was observed in group II. Histopathologically, the carbon fiber implant induced extensive fibrous tissue (collagen fiber) reaction. Negligible inflammatory cells in the stroma indicate the host tissue tolerance to carbon fibers. Histochemically, gradually increased alkaline phosphatase activity up to day 14 in group I, suggested the proliferation of fibroblasts in early stages.

We experienced two cases of dissecting aneurysm[DeBakey type III] of the thoracic aorta treated using intraluminal sutureless graft. Controversy still exists about the exact timing of surgical intervention for dissection of the descending thoracic aorta. The surgical indication of dissecting aneurysm[DeBakey type III] is continuous flow in the false lumen, continuous chest pain, compromise of arterial supply to a specific organ or limb, or extension of the dissection while the patient is receiving satisfactory medical treatment. Surgical therapy for dissection of the aorta has had a high mortality. One contributing factor has been hemorrhage from the prosthesis and the suture lines. Recently, a new method of treatment with a intraluminal sutureless graft that requires no end-to-end anastomosis has been developed. In our cases, cardiopulmonary bypass and circulatory arrest was utilized in repairing dissecting aneurysm of descending aorta[DeBakey type III] in order to avoid the aortic cross clamping because of friable aortic intima. The basic technique consists of vertical incision of descending aorta in the area of intimal tear and inserting the whole ringed graft into the true lumen of the dissected aorta and circumferentially ligating the aorta against the groove in the rings. Postoperative course was uneventful.
