The results of conventional operative resection of diffuse subaortic stenosis[tunnel subaortic stenosis] have been less than satisfactory. We have performed modified Konno operation to enlarge the outflow tract of both ventricle with a patch in three patients with diffuse tunnel subaortic stenosis in the department of Thoracic and Cardiovascular Surgery, Seoul National University Children`s Hospital. Preoperative left ventricular aortic pressure gradients were 135 mmHg, 50 mmHg, 80 mmHg respectively in these patients. After right ventriculotomy, the septotomy was done and extended beyond the limit of the stenosis and fibrous and/or muscular tissue was removed from each edge of septal incision. After adequate widening of the tunnel subaortic stenosis with various patches, right ventricle was closed primarily or with prosthetic patches successfully. One patient who was diagnosed as complete atrioventricular septal defect had complete AV block preoperatively and was implanted permanent pacemaker, and others who were sinus rhythm preoperatively have no serious postoperative rhythm disturbance. One patient developed mild postoperative aortic insufficiency and one who had preoperative aortic insufficiency has still same grade of aortic insufficiency after operation. All had good postoperative hemodynamics without any postoperative residual pressure gradient.

심장수술후 심근의 부종, 심근이완, 심한 술후 출혈 등이 동반된 환자에서는 흉골봉합에 의해 심한 혈역학적 장애가 발생된다. 심한 심부종으로 흉골 봉합시 흉골 일부분에 의한 심압박에도 혈혁학적 장애를 일으키는 경우도 있다. 본 교실에서는 54세의 비만 여성에서 관상동맥 우회술후 Synthes DCP wide plate를 이용한지 연성 흉골 봉합을 경험하였으며, 이러한 지연성 흉골봉합이 심부종이 심한 환자에서는 상당히 효과적이고 간단한 방법임을 확인하였다. 관상동맥 우회술후 16시간만에 성공적으로 지연성 흉골봉합을 경칩하여 좋은 성적을 얻었기에 보고 하고자 한다. Severe hemodynamic dysfunction may follow after the closure of the median sternotomy in patients with myocardial edema, cardiac dilatation, and severe postoperative bleeding. In extreme cases, myocardial edema may be so severe that cardiac function is compromised merely by the edges of the open sternum touching the heart. Sternotomy remained open and delayed sternal closure is already described adjunct in complicated cardiac operations. We experi nced a case of delayed sternal closure after 16 hours of CABG using synthes DCP wide plate in a 54-year old obese female patient. Our experience conims that delayed sternal closure Is an effective at simple means of dealing with severe myocardial edema so we report this case with literature review.

Modified Blalock-Taussig operation remains the standard technique of systemic-to-pulmonary artery shunt in patients of congenital heart disease with decreased pulmonary blood flow. We reviewed the 41 patients who had been performed modified Blalock-Taussig operation from March 1985 to Feb. 1988, and angiographically measured pulmonary artery size before and after shunt, and calculated pulmonary artery index [PAI] and ratio of left and right pulmonary artery to descending aorta[[LPA+RPA]/dAo]. The mean duration of palliation after shunt operation was 624 days and mean age of the patient at shunt operation was 3.59 years. Mean PAI increased significantly from 131.15*67.11 mm2/M2 preoperatively to 232.70*84.46 mm2/M2 postoperatively. Mean ratio of right and left pulmonary artery to descending aorta also increased significantly from 1.48*0.40 preoperatively to 1.92*0.50 postoperatively. All patients manifested clinical improvement; there was mean decrease in hematocrit of 8.95%, mean increase in arterial oxygen saturation of 11.08%. Pulmonary arterial growth was not influenced by age at operation, initial pulmonary artery size, or graft size, but significantly influenced by antegrade flow. The patients who have some antegrade flow were in more increase of PAI. There were no linear correlation between change of PAI, change of [[LPA+RPA]/dAo], SaO2, and duration. But, according to Scatterplot between change of PAI and duration, some complex correlation was suggested and mean PAI was decreased after 2-year palliation. We concluded that modified Blalock-Taussig operation is excellent palliative surgery for pulmonary artery growth especially on the patient who have some antegrade flow, and the proper duration of palliation was about 2 years.
선천성 심장기형 환자에서 조기술후 심실 전부하 용적과 심박출량의 상호 관계 및 혈역학적 변화 분석

Postoperative cardiac performance of cyanotic congenital heart disease is somewhat different from that of other cardiac diseases. For the evaluation of postoperative cardiac performance in the cyanotic congenital heart disease we measured cardiac output by thermodilution technique at 1, 4, 8, 12, 16, 20, 24, 36, 48 postoperative hours in 14 patients operated from Feb. 1989 to Nov. 1989 in The Department of Thoracic and Cardiovascular Surgery, Seoul National University Children`s Hospital. At the same time, we checked left atrial pressure [LAP], central venous pressure [CUP], and mixed venous oxygen saturation [SvO2] to detect correlation between them. Immediate postoperative cardiac index was 3.585 $\pm$ 0.945 L/min/m2, and it decreased maximally to 3.322$\pm$1.007 L/min/m2 at postoperative 16 hours. After then it increased and stabilized from 36 hours after operation, and its value was 4.426$\pm$1.358 L/min/m2. There were no correlations between cardiac index and left atrial pressure or central venous pressure. Between mixed venous oxygen saturation and cardiac index, there was no correlation in the early postoperative period but after postoperative 16 hours, there was significant correlation between them and correlation coefficients were 0.573 [16hrs], 0.743 [20hrs], 0.436 [24hrs], 0.560 [36hrs], 0.636 [48hrs], respectively. From these results, we concluded that in the corrective surgery of cyanotic congenital heart disease, cardiac performance was depressed in the early postoperative period. It improved from postoperative 16 hours, and stabilized from 36 hours after operation. During early postoperative period, mixed venous oxygen saturation should not be used as a predictor of cardiac performance but it could be used as a predictor of cardiac performance from 16 hours after operation.

Pulmonary aspergilloma resulting from colonization of Aspergillus fumigatus is potentially life-threatening disease due to massive hemoptysis. Between August 1990 and November 1993, twelve patients were operated for the treatment of pulmonary aspergilloma. The mean age was 38.8 years. All patients had underlying cavitary lung disease, and the tuberculosis is the most common cause. Ten patients have experienced hemoptysis, but the clinical presentation of hemoptysis at the time of operation was mostly intermittent and scanty. Operative procedures were segmentectomy in 1 patient, lobectomy in 8, pneumonectomy in 2, and pleuropneumonectomy in 1. There were three complications, bronchopleural fistula in one patient and prolonged air leak in 2. There was no postoperative death. Conclusively, our results suggest that established aspergilloma associated with tuberculosis or other cavitary lesions should undergo early elective pulmonary resection, even though it has only minimal hemoptysis.
