좌관상동맥동과 비관상동맥동에서 발생하여 좌심실로 파열된 발살바동 동맥류에 기인한 울혈성 심부전을 주소로 내원한 37세 남자 환자의 수술적 체험 1예를 보고하고자 한다. 술전 심초음파에서 발살바동 주위의 낭성 구조물이 관찰되었고 좌심실 비대와 심한 대동맥판폐쇄부전이 관찰되었고 발살바동맥류와 대동맥-좌심실터널을 감별진단의 범주에 두었다. 수술 소견에서 좌관상동맥동과 비관상동맥동 모두 좌심실로 통하는 누공을 가지고 있었다. 좌심실로 파열된 누공은 bovine pericardium으로 봉합하였으며 대동맥근부는 21 mm St. Jude Epic Supra tissue valve와 24 mm Hemashild의 복합도관을 사용하여 교정된 Bentall 수술을 시행하였다. 환자는 수술 후 15일째 퇴원하였으며, 2개월간 정기적으로 외래추적 관찰중이다. 이에 저자들은 본 질환의 희귀성과 함께 수술적 방법을 알리고자 증례보고 하는 바이다.

배경: Dubost 등이 1952년에 실시한 신동맥 하부 대동맥류 수술을 시작으로 복부 대동맥류의 근치적인 수술적 치료가 시작되었다. 최근에 경피적 대동맥 스텐트 삽입술의 비약적인 발전으로 외과적 수술이 감소하고는 있으나, 여전히 근치를 위한 치료로 인정되고 있다. 저자들은 지난 6년간 시행한 복부 대동맥류의 수술성적 및 그 예후에 미치는 영향인자에 대해 분석하여 보았다. 대상 및 방법: 2002년 3월부터 2008년 3월까지 복부 대동맥류로 수술 받은 환자 18명을 대상으로 하였다. 수술의 적응은 파열, 60 mm 이상의 최대직경, 크기의 증가, 내과적으로 조절 안되는 고혈압이나 통증이 있는 경우 등이었다. 결과: 환자들의 평균 나이는 $66.6{\pm}9.3$세$(49\sim81)$였고, 남자가 12명(66.7%), 여자가 6명이었다. 신동맥 상부까지 진행된 경우는 6명(33.3%), 장골동맥까지 진행된 경우는 13명(72.2%)이었다. 진단 당시 대동맥이 파열되어 있었던 환자들은 5명(27.8%)이었다. 대동맥의 평균 최대직경은 $72.2{\pm}12.9$ mm ($58\sim109$ mm)였다. 수술은 모두 정중 복부절개를 통한 복강 내 접근으로 시행하였고, 응급수술은 6명의 환자에서 시행하였다. 대동맥 겸자 후 양쪽 하지로 혈류개통이 될 때까지의 허혈시간은 평균 $82{\pm}42$분($35\sim180$분)이었다. 전체 환자 중 3명이 사망하여 전체 사망률은 16.7%였고, 파열된 환자의 사망률은 60%, 파열되지 않은 환자의 사망률은 0%였다. 수술 후 합병증으로는 신부전, 대퇴등 정맥 폐쇄, 창상감염이 각 1예씩 있었다. 생존 환자들은 $34{\pm}26$개월($4\sim90$개월)간의 추적관찰 기간동안 대동맥 내 문제는 없이 장기생존 중이다. 사망에 영향을 주는 인자로는 파열, 응급수술이 의미 있었다(p<0.05). 결론: 파열된 복부대동맥류에 대한 응급수술은 여전히 높은 사망률을 보이나, 파열되지 않은 복부대동맥류의 수술은 비교적 안전하게 진행할 수 있으며 수술 후 생존한 환자는 장기생존을 보인다. 비록 경피적 대동맥 스탠트 삽입술이 최근의 치료 경향이나 종래의 수술방법도 만족할 만 한다.

Background: Although patients with a ruptured abdominal aortic aneurysm (RAAA) often reach the hospital alive, the perioperative mortality is still very high. We retrospectively reviewed thirty patients who underwent repair of RAAA to identify the factors affecting postoperative mortality in a single hospital. Materials and Methods: Between September 2007 and May 2011, thirty patients with RAAA underwent emergent surgery (n=27) or endovascular aneurysm repair (n=3). Their medical records were retrospectively reviewed regarding three categories: 1) preoperative patient status: age, gender, vital signs, serum creatinine, blood urea nitrogen, hematocrit, and hemoglobin level: 2) aneurysmal status: size, type, and rupture status; and 3) operative factors: interval time to operating room, operative duration, and amount of perioperative transfusion. Results: The 30-day postoperative mortality rate was 13.3% (4/30); later mortality was 3.3% (1/30). On multivariate analysis, the initial diastolic blood pressure (BP), interval time to operating room and amount of preoperative packed cell transfusion were statistically significantly linked with postoperative mortality (p<0.05). Conclusion: In this study, preoperative diastolic BP, preoperative packed cell transfusion amount and interval time between arrival and entry to operating room were significantly associated with postoperative mortality. It is important to prevent hemorrhage as quickly as possible.

68세된 남자로 좌측과 후측 흉부에 통증을 주소로 내원하였다. 술전 시행한 흉복부 W scan에서 대동맥류는 좌측 쇄골하동맥에서 횡격막까지 연결되었고 긴박성 파열의 소견도 보였다. 또한 술전 관동맥조영술에서는 좌회선동맥에 95%, 좌전하행지에 50%의 협착소견을 보였다. 수술은 고동맥-고정맥 우회술을 하면서 좌측 제 4늑간을 통하여 측후방 개흉절개를 하여 수술시야를 확보하였고 대동맥을 차단한뒤 대동맥류를 절개하고 인조혈관으로 대치하였다. 그리고 심박동하에서 대복제정 맥을 이용하여 좌회선동맥의 두번째 둔각변연동맥과 좌측 쇄골하동맥 기시부에 관상동맥 우회술을 하였다. 술후 환자는 술중 저혈압성 쇼크와 저산소증으로 다발성 뇌경색의 합병증을 보였다.

Background: The aim of this study was to report our early experiences with the endovascular repair of ruptured descending thoracic aortic aneurysms (rDTAAs), which are a rare and life-threatening condition. Methods: Among 42 patients who underwent thoracic endovascular aortic repair (TEVAR) between October 2010 and September 2015, five patients (11.9%) suffered an rDTAA. Results: The mean age was $72.4{\pm}5.1years$, and all patients were male. Hemoptysis and hemothorax were present in three (60%) and two (40%) patients, respectively. Hypovolemic shock was noted in three patients who underwent emergency operations. A hybrid operation was performed in three patients. The mean operative time was $269.8{\pm}72.3minutes$. The mean total length of aortic coverage was $186.0{\pm}49.2mm$. No 30-day mortality occurred. Stroke, delirium, and atrial fibrillation were observed in one patient each. Paraplegia did not occur. Endoleak was found in two patients (40%), one of whom underwent an early and successful reintervention. During the mean follow-up period of $16.8{\pm}14.8months$, two patients died; one cause of death was a persistent type 1 endoleak and the other cause was unknown. Conclusion: TEVAR for rDTAA was associated with favorable early mortality and morbidity outcomes. However, early reintervention should be considered if persistent endoleak occurs.

Purpose: In the treatment of aortic aneurysm, endovascular stent-graft application has become an established method of treatment. To observe the outcomes of the procedure as the size change of aneurysm in relation with endoleak, a retrospective analysis was done for the consecutive cases who undertook the procedure. Materials & Method: Stent-graft was applied to the aortic aneurysm in 33 patients. The location of the aneurysm was thoracic in 11 patients and abdominal in 22 patients. CT angiographic was done for the follow-up evaluation to analyze the aneurysm size and the presence of endoleak. Results: Technical success rate was 97% (32/33). The primary success rate without endoleak was 84% (28/33). The secondary success was 90% (30/33). During the follow-up period of 3 months to 7years and 6months in 26 patients, a secondary endoleak developed in 5 cases. Post-implantation syndrome developed in 17 cases (51%). Among the 14 cases with follow-up imaging data for size, endoleak was negative in 10 cases. The aneurysm decreased in 5 cases, stable in size in 4 cases and enlarged in one case (10%).Among the 4 cases with endoleak positive, the aneurysm enlarged in two cases (50%). Conclusion: In the stent-graft application for aortic aneurysm, there is high chance of decrease of aneurysm size in those cases with endoleak negative. However, the aneurysm may increase and eventually rupture in the cases with en do leak positive. Close observation with CT angiography is necessary for the evaluation for the presence of endoleak and size change.

A 66-year-old male patient arrived at the emergency room with a crush injury to his chest. Multiple rib fractures, hemothorax on both sides, left scapular fracture, liver laceration, and retroperitoneal hematoma were found upon the radiologic examination. After closed thoracostomy, the patient had been initially admitted to the intensive care unit, but he was transferred to the general ward on the next day. On the 4th post-trauma day, the patient complained of severe pain and there was bloody drainage through the chest tube. This case is an exploration with the consideration of the possibility of major bleeding and the subsequent repair of the descending thoracic aorta. This case is regarded as a case in which the aorta wall was damaged as the sharp margin of the fractured ribs caused continuous irritation.

The first Mitral Commissurotomy was performed for tight mitral stenosis on March 1957. The patient was at that time 22-year-old male, student. The longest follow 9p for 22 years and 8 months has been obtained. During the follow up period, late deterioration due to restenosis developed 4 years after initial good result and reoperation was succeeded by transventricular Mitral Valvotomy with Tubb`s ilator on April 1964. The possible cause of restenosis was attributed to recurrent rheumatic activity. After more than 13 years long-good life following 2nd operation, Endocarditis such as episode of high fever & chill intermittently followed by mild fever and night sweat, I t. tibial artery embolization and rupture of aortic cusp. At present, patient complained of no subjective symptom, enjoying ordinary life {NYHA II]. Blood pressure has been 110/50-60 mmHg, trivial diastolic murmur at apex and moderate degree of mechanical murmur on diastole at Erb`s rea. Neither signs of RVH for mitral stenosis nor sign of LVH. ST-T change for aortic regurgitation appeared yet during last 2 yrs. The patient`s are for prevention of Rheumatic activity and development of endocarditis is important for obtaining the better long-term result.
