승모판성형술 직후에 시행한 재수술에 대한 연구보고는 많지 않다. 저자들은 승모판성형술 직후 성형술 실패로 판단되는 환자에서 즉시 시행한 재수술 결과에 대해 알아보았다. 대상 및 방법: 1995년 4월부터 2001년 7월까지 세종병원에서 승모판성형술을 받은 환자 중 체외순환 이탈 직후 시행한 경식도초음파 검사에서 승모판막폐쇄부전 혹은 협착이 의미있게 잔존하거나 다른 이유로 재수술이 즉시 필요하였던 18명을 대상으로 후향적으로 조사하였다. 남녀비는 5 : 13이었고 평균 연령은 44세였다. 승모판막 질환은 폐쇄부전 12명, 협착 3명, 그리고 혼합형이 3명이었다. 원인은 류머치스성 9명, 퇴행성 8명, 그리고 심내막염이 1명이었다. 재수술의 원인은 잔존 승모판폐쇄부전 13명, 협착 4명, 그리고 좌심실천공이 1명이었다. 14명(77.8%)에서 재성형술을, 4명에서는 인공기계판막치환술이 시행되었다. 결과: 조기사망은 없었다. 조기결과는 승모판막치환을 한 4명을 제외한 14명 중 13명(92.9%)에서 0-I도의 폐쇄부전을 보였고 협착은 14명 모두 경도 이하 상태였다. 평균 33개월을 추적조사 한 결과 1명이 술 후 4개월 후 심기능부전으로 사망하였다. 승모판폐쇄부전은 9명(64.3%)에서 0-I도를, 승모판협착은 11명(78.6%)에서 경도 이하였고 재수술은 1명에서 시행되었다. 6년 생존율과 재수술로부터의 자유도는 각각 94%와 90%였다. 4년 후 승모판폐쇄부전 및 협착 재발로부터의 자유도는 각각 56%와44%였다. 결론: 승모판막성형술 직후 재수술은 양호한 조기 및 중기 생존율을 보이며 일차성형술 실패 후에도 높은 빈도에서 재성형술이 가능하다. 하지만 재성형술 시 특히 류머치스성 판막질환에서는 판막 기능부전 발생률이 높기 때문에 성형술 후 판막부전의 재발을 줄이기 위해서는 성형술의 적절한 적용 및 적응증 선별이 중요할 것으로 생각된다.

Background: Reoperations on the aortic root or the ascending aorta are being performed with increasing frequency and remain a challenging problem. This study was performed to analyze the results of reoperations on the ascending aorta and aortic root. Material and Method: Between May 1995 and April 2001, 30 patients had reoperations on the ascending aorta and aortic root and were reviewed retrospectively. The mean interval between the previous repair and the actual reoperation was 56 months(range 3 to 142 months). Seven patients(23.3%) had two or more previous operations. The indications for reoperations were true aneurysm in 7 patients(23.3%), prosthetic valve endocarditis in 6(20%), false aneurysm in 5(16.7%), paravalvular leak associated with Behcet's disease in 4(13.3%), malfunction of prosthetic aortic valve in 4(13.3%), aortic dissection in 3(10%), and annuloaortic ectasia in 1(3.3%). The principal reoperations performed were aortic root replacement in 17 patients(56.7%), replacement of the ascending aorta in 8(26.7%), aortic and mitral valve replacement with reconstruction of fibrous trigone in 2(6.6%), patch aortoplasty in 2(6.6%), and aortic valve replacement after Bentall operation in 1 (3.3%). The cardiopulmonary bypass was started before sternotomy in 7 patients and the hypothermic circulatory arrest was used in 16(53.3%). The mean time of circulatory arrest, total bypass, and aortic crossclamp were 20$\pm$ 12 minutes, 228$\pm$56 minutes, and 143$\pm$62 minutes, respectively Result: There were three early deaths(10%). The postoperative complications were reoperation for bleeding in 7 patients(23.3%), cardiac complications in 5(16.7%), transient acute renal failure in 2(6.6%), transient focal seizure in 2(6.6%), and the others in 5. The mean follow-up was 22.8 $\pm$20.5 months. There were two late deaths(7.4%). The actuarial survival was 92.6$\pm$5.0% at 6 years. One patient required reoperation for complication of reoperation on the ascending aorta and aortic root(3.7%). The 1- and 6-year actuarial freedom from reoperation was 100% and 83.3$\pm$15.2%, respectively. One patient with Behcet's disease are waiting for reoperation due to false aneurysm, which developed after aortic root replacement with homograft. There were no thromboembolisms or anticoagulant related complications. Conclusions: This study suggests that reoperations on the ascending aorta and aortic root can be performed with acceptable early mortality and morbidity, and adequate surgical strategies according to the pathologi conditions are critical to the prevention of the reoperation.

As the experience of coronary artery bypass grafting (CABG) has been accumulated, the number of reoperation after CABG is increasing. We analyzed our clinical experience of redo-CABG. Material and Method: Fourteen patients who underwent redo-CABG between Jan. 1994 and Dec. 2002 were included in this study. The mean period from the first operation to reoperation was 66$\pm$56 (3∼157) months, and the average ages were 62.8$\pm$8.7 (51∼78) years. The survivors were followed up 39$\pm$29 (4∼101) months postoperatively. Indications of reoperation were stenosis or occlusion of previous grafts in 11 patients, progression of native coronary artery disease in one patient, and both etiologies in two patients. Result: There were two in-hospital mortalities (14.3%) resulting from low cardiac output syndrome, Postoperative morbidities were perioperative myocardiac infarction in 2 patients (14.3%), mediastinitis in one patient (7.2%), duodenal perforation in one patient, ischemic necrosis of the lower extremity in one patient, gastric perforation after mesenteric infarct in one patient, delayed brain infarct in one patient, and intraoperative splenic rupture in one patient. There was one late mortality at six months postoperatively during the follow up. There was no angina recurrence during the follow up. Conclusion: Although redo CABG demonstrated relatively high operative mortalities and morbidities, postoperative status and clinical outcome of the survivors were favorable.

Recently, the number of coronary artery bypass surgery(CABG) is increasing according to the increasing incidence of coronary artery disease. However, CABG is not a definite corrective surgery; therefore, in some patients, redo-CABG may be required. We retrospectively reviewed our redo-CABG experiences to help future redo-CABG. Material and Method: From January 1991 to April 2001, 14 cases of redo-CABG were performed in Yonsei Cardiovascular Center(M:F＝12:2) and mean age was 61,7 $\pm$ 7.1(47-72) years. Mean time from 1st. CABG to redo-CABG was 121.9 $\pm$ 50.5(6.1-179.6) months. Thirteen cases were conventional on-pump CABG and one case was off-pump CABG. In two patients, mitral valve re-replacement and mitral valve repair were performed each. All redo-CABG were performed through mid-sternotomy. During redo-CABG, left internal mammary artery and saphenous vein grafts were used in 6 patients, left internal mammary artery and left radial artery grafts were used in 2 patients, left internal mammary artery and gastroepiploic artery were used in one patient and only greater saphenous veins were used in 5 cases(In one case, cephalic vein was also used). The number of mean distal anastomosis was 2.1 $\pm$ 0.9(1-4). Result: There were no operative death and no perioperative myocardial infarctions and cerebrovascular accidents or other heart related complications. Mean follow up duration was 40.1 $\pm$ 38.6(1.1-118.5) months. During follow up period, angina was re-developed in one patient 13 months after operation. Two patients died of end-stage renal failure 14.8 months and 116.3 months after redo-CABG, respectively. During follow up period, coronary angiography was performed in 3 patients, and all grafts were patent. At last follow up, mean Canadian class was 1.3. Kaplan-Meier survival at 9 years was 90.0 $\pm$ 9.5% and event free survival at 9 years was 71.4 $\pm$ 6.9%. Conclusion: After redo-CABG, all patients improved their angina symptom and daily activity. And long-term survival after redo-CABG was excellent. Therefore, if patients have indications for redo-CABG, thenredo-CABG must be strongly recommended and performed.

The purpose of this study was to construct a hypothetic model for the influential theoretical variables for the facial cosmetic resurgery intention of female college students with cosmetic surgery experience and to examine the compatability of the re-surgery intention model with real data. The subjects in this study were 320 selected female college students who had undergone cosmetic surgery. After a survey was conducted from July 15 to September 20, 2014, the answer sheets from 300 respondents were gathered, and the answer sheets from 295 respondents were analyzed except for the five ones that included uncertain answers. As a result, it's ascertained that cognitive dissonance was under the direct influence of post-surgery satisfaction with appearance, self-esteem, subjective norm and lookism.. Self-esteem, subjective norm and lookism had a direct impact on resurgery intention, and self-esteem and lookism affected resurgery intention both in direct and indirect ways through the medium of cognitive dissonance. The findings of the study are expected to provide useful information on the development of nursing intervention programs geared toward promoting physical and mental health.

Transabdominal approach in redo coronary artery bypass grafting(CABG) may avoid the risk related to repeat sternotomy. Redo CABG using this approach can be performed safely in selected cases. We report a case of redo off-pump CABG through a transabdominal approach in a 59-year-old woman with recurrent unstable angina after a previous CABG. Through a curvilinear epigastric incision, right gastroepiploic artery(RGEA) was harvested as a graft, and the RGEA-to-right coronary artery anastomosis was performed on the beating heart. A 1-day postoperative angiographic study showed the patent RGEA graft, and she was discharged on postoperative 4th day without any complication.

The incidence of reoperative coronary artery bypass grafting (CABG) has increased because of the rise in the number of patients who have undergone initial CABG. In addition, recent technological advances have resulted in widespread application of off pump coronary artery bypass (OPCAB). We report a case of redo OPCAB through thoracotomy and small laparotomy in 76-year-old man with recurrent unstable angina.

From September 1989 to March 1996, 13 patients with prosthetic valve thrombosis underwent reoperdtion on 16 occasions. The mean interval between implantation and reoperation was 27.8 months. The anticoagulation status was inadequate in 44% of th Instances. The majority(75%) were in NYHA functional class IV, 6 of them being in shock. Reoperation was performed for valve replacement(15 of 16 occasions) or thrombectomy(1 of 16 occasions) within 3 to 192 hours(mean 33.5 hours). Operative mortality at reoperation was 25%(4 patients). Re-thrombosis occurred In 3 patients. Long-term outcome was satisfactory in all survivors with a mean follow-up of 30.B months. The present results indicate that an early diagnosis and prompt surgical intervention is needed to decrease operative mortality.

We analysed the surgical outcomes of immediate reoperations after mitral valve repair. Material and Method: Eighteen patients who underwent immediate reoperation for failed mitral valve repair from April 1995 through July 2001 were reviewed retrospectively. There were 13 female patients. The mitral valve disease was regurgitation (MR) in 12 patients, stenosis (MS) in 3, and mixed lesion in 3. The etiologies of the valve disease were rheumatic in 9 patients, degenerative in 8, and endocarditis in 1. The causes of reoperation was residual MR in 13 patients, residual MS in 4, and rupture of left ventricle in 1. Fourteen patients had rerepair for residual mitral lesions (77.8%) and four underwent replacement. Result: There was no early death. After mean follow-vp of 33 months, there was one late death. Echocardiography revealed no or grade 1 of MR (64.3%) in 9 patients and no or mild MS in 11 patients (78,6%). Reoperation was done in one patient. The cumulative survival and freedom from valve-related reoperation at 6 years were 94% and 90%, respectively. The cumulative freedom from recurrent MR and MS at 4 years were 56% and 44%, respectively. Conclusion: This study suggests that immediate reoperation for failed mitral valve repair offers good early and intermediate survival, and mitral valve rerepair can be successfully performed in most of patients. However, because mitral rerepair have high failure rate, especially in rheumatic valve disease, adequate selections of valvuloplasty technique and indication are important to reduce the failure rate of mitral rerepair.
