  • 본 연구에서 지난 17년간 경험한 부분방실중격결손증의 외과적 교정술의 장기결과를 후향적으로 분석하였다. 대상 및 방법: 1986년 4월부터 2002년 12월까지 부분방실중격결손증으로 외과적 교정술을 시행 받은 93명의 환자를 대상으로 사망률, 생존율 및 그 위험인자를 분석하고, 추적관찰 기간중 재수술과 관련되는 위험인자를 분석하였다. 남자 환자가 32명 여자 환자가 61명이었으며, 수술 당시 연령의 중앙값은 68개월(3∼818개월)이었고 평균추적관찰기간은 108$\pm$59.4개월(1∼200개월)이었다. 결과: 조기사망은 4예로 수술 사망률은 4.3%였다. 사망원인은 발작성 폐동맥고혈압증 1예, 저심박출증 1예, 심부전에 의한 심폐기이탈실패 1예, 심실세동 1예였고, 사망과 관련하여 통계적으로 의미 있는 인자는 없었다. 조기사망한 환자 4명을 제외한 89명의 환자를 추적 관찰하였고, 1예에서 만기사망을 확인하였다. 3년, 5년, 10년, 15년 생존율은 각각 95.7%, 94.3%, 94.3%, 94.3%였다. 수술 직후 63명(67.7%)의 환자에서 좌측 방실판막폐쇄부전이 개선되었고, 14명(15.1%)의 환자에서는 술 전과 같았고, 12명(12.9%)에서는 악화되었다. 추적관찰 기간 중 8명(9.0%)의 환자에서 재수술을 시행하였으며, 완전 교정술 후 평균 38.6개월(3∼136개월) 후 시행되었다. 3년, 5년, 10년, 15년 무재수술 생존율은 각각 94.0%, 91.4%, 91.4%, 88.2%였다. 재수술의 원인으로는 좌측 방실판막페쇄부전이 7예, 좌심실유출로협착이 2예, 잔존심방중격결손 1예, 좌측 방실판막협착 1예, 우심부전 1예였고, 재수술과 관련하여 좌심실 유출로 협착이 통계적으로 의미있는 위험인자였다(p=0.002). 10명의 환자에서 술 후 부정맥이 발생하였는데, 3명의 환자에서 상심실성 부정맥, 7명의 환자에서는 완전 방실전도차단이 발생하였고, 이 중 6명의 환자에서 영구 인공심박조율기의 삽입이 필요하였다. 걸론: 부분방실중격결손증은 낮은 사망률로 수술을 시행할 수 있었다. 재수술의 원인은 좌측 방실판막페쇄부전이 가장 많았다. 방실판막구조물의 기형이 동반된 경우 재수술의 가능성이 높아지는 경향을 보였으나 통계적 의미는 없었다. 또한, 술후 좌심실유출로협착여부가 재수술의 위험인자였으므로 좌측 방실판막 및 좌심실 유출로의 해부학적인 구조에 대한 정확한 이해가 요구된다. 좌심실유출로협착은 발생시 대동맥하부의 조직에 대한 절제술을 시행할 수 있으나 재발 가능성이 크고, 필요시 수정 Konno수술로 만족할만한 결과를 얻을 수 있었다. 또한, 방실전도차단은 초기시행단계에서 많이 발생하였으며, 심장 전도계에 대한 정확한 해부학적 이해와 경험축적으로 극복할 수 있었다.

  • A 65-year-old man who had lateral cervical disc herniation underwent cervical posterior laminoforaminotomy at C5-6 and C6-7 level right side. During the operation, there was no serious surgical bleeding event. After operation, he complained persistent right shoulder pain and neck pain. Repeated magnetic resonance image (MRI) showed diffuse cervical epidural hematoma (EDH) extending from C5 to T1 level right side and spinal cord compression at C5-6-7 level. He underwent exploration. There was active bleeding at muscular layer. Muscular active bleeding was controlled and intramuscular hematoma was removed. The patient's symptom was reduced after second operation. Symptomatic postoperative spinal EDH requiring reoperation is rare. Meticulous bleeding control is important before wound closure. In addition, if patient presents persistent or aggravated pain after operation, rapid evaluation using MRI and second look operation is needed as soon as possible.

  • 최근 심폐기를 사용하지 않는 최소침습성 직접 관상동맥우회술(MIDCAB procedure)은 심장수술 분야에서 급속도로 발전을 거듭하고 있다. 금번 저자들은 전에 만들어 준 좌전하행지 이식편이 막혀 관상동맥 재수술을 필요로 하였으나 좌내 유동맥의 혈류량의 불충분하였다고 생각되었다. 1례에서 최소 침습 수기를 통한 액와-관상동맥 우회술을 시행하여 만족스러운 결과를 얻었기에 문헌고찰과 함께 보고하고자 한다.

  • The emergence and expansion of cardiac surgery over the past decade has resulted in an increasing number of patients undergoing cardiac operations but many kinds of heart surgery was realized only palliative, resulting in increasing numbers of secondary cardiac procedures. From 1978 to 1988, 10 cases of various congenital heart diseases and 17 cases of acquired heart diseases were reoperated at Hanyang University Hospital. The leading indication of second operation was residual shunt or valvular malfunction due to technical failure in congenital heart disease and primary valve failure, endocarditis, paravalvular leakage were for acquired heart disease. The mortality of reoperation was 0% for congenital heart disease and 11.7%[2 death among the 17 patients] for acquired heart disease. The leading causes of death were myocardial failure, sepsis with endocarditis, acute renal failure and congestive heart failure.

  • A patient with intravascular hemolysis due to residual shunt and right ventricular outflow track obstruction after total correction of TOF was presented. The patient was 29 years old female. She underwented VSD closure with dacron patch, infundibulectomy, pulmonic valvotomy and direct closure of PFO. 8 months after the operation, severe intravascular hemolysis and hemolytic anemia appeared. Conservative therapies were not effective, her general condition and laboratory finding got worse gradually. She underwent reoperation, the shunt was closed and right ventricular outflow tract obstruction was corrected by pulmonary valvotomy, infudibulectomy and transannular patch. After operation, hemolysis disappeared dramatically. Severe hemolysis may induce renal failure and necessitate transfusion frequently. If hemolytic anemia is not corrected by conservative treatment, early reoperation is required.

  • From 1985 to 1990, a total of 160 new valves were implanted for 125 adult patients to whom prosthetic valve replacement had been performed [One patient had consecutive 2 reoperations]. Following data are the results from the follow-up study from January 1985 to February 1991. Mean age of the patients was 37.9$\pm$12.1 years. Mean follow-up period was 25.8$\pm$18.8 months. In bioprosthesis, mean interval between the previous operation and reoperation was 85.6$\pm$36.4 months in aortic valve, and 87.3$\pm$30.0 months in mitral valve. The causes of reoperation were prosthetic valve failure[103 patients, 81.7%], prosthetic valve endocarditis[17 patients, 13.5%], periprosthetic leakage[5 patients, 4.0%], and aneurysm of ascending aorta[1 patient, 0.8%]. Fourteen patients[11.1%] died in hospital; 5 in 22 replacement of aortic valve[22.7%], 6 in 73 rereplacement of mitral valve[8.2%], and 3 in 31 replacement of multiple valves [9.7%] Except for 3 intraoperative deaths, postoperative, major and minor complications occurred in 39 patients[31.0%]. And the actuarial 5-year survival rate of operative survivors was 95.5$\pm$8.6%.

  • From July 1966 to July 1983, sixteen atrial myxomas in fifteen patients were seen at Severance Hospital. Fifteen of the sixteen myxomas were located in the left atrium and one in the right atrium. All the cases except three were correctly diagnosed preoperatively. Presently, M-mode and two-dimensional echocardiography are utilized as safe, reliable, and noninvasive imaging modalities. Echocardiography provided an accurate diagnosis in twelve cases since November 1977. In all cases, myxoma were excised successfully. On patient had reoperation and mitral valve replacement on postoperative first day due to persist mitral regurgitation after excision of left atrial myxoma. One patient had recurrence requiring reoperation 37 months after primary operation. Follow up results of each patient were excellent.

  • Intravascular hemolysis occurs in the majority of patient with mechanical valve prosthesis. The primary cause is mechanical trauma to red cells from turbulent blood flow through the prosthesis. Degree of hemolysis is dependent upon the type, size and material of valve and aggravated by paravalvular leakage. Clinically important hemolytic anemia is required medical management or consideration of reoperation. In severe hemolysis, reoperation is recommended without delay when seems to be renal failure. In this case, postoperative severe mechanical hemolysis was developed immediately after aortic valve replacement with St. Jude medical valve in a 13 year-old male patient. Neither significant paravalvular leakage nor valvular dysfunction was found through redo, but the mechanical valve was strongly suspected the cause of severe hemolysis. The St. Jude Medical valve was changed with Ionescu-Shiley bioprosthesis and any significant clinical problems were not noted through the postoperative course.
