The usual treatment for aortic aneurysms is surgical replacement with a prosthetic graft; however the associated morbidity and mortality rates must be considered. Endovascular placement of self-expandable stent-graft is a safe noninvasive treatment that can be an alternative to the surgical repair, the postoperative course of the 2 cases of thoracoabdominal aortic aneurysms was uneventful and no complication has been associated with the stent-graft during the 17 months and 5 months follow-up studies,.

흉복부대동맥류 질환에서 고전적인 수술은 고위험군 환자에서 아직까지 높은 합병증 발생과 사망률을 나타낸다. 최근에는 스텐트 그라프트를 이용한 혈관내 시술(endovascular repair)이 시행되고 있으나 내장동맥의 보존이 시술의 걸림돌이 되고 있다. 저자들은 2명의 고위험군 흉복부대동맥류 환자에서 내장동맥 우회술과 흉복부대동맥에 스벤트 그라프트를 삽입하는 하이브리드 술식을 이용하여 성공적으로 치료하였다.

We experienced 12 patients with the abdominal aortic aneurysm during last 31 years [Dec. 1958 \ulcornerSep. 1989]. Among them, 10 patients were reviewed. They were all male. The age ranged from 34 to 80 years with the mean age of 59.4 years. The etiology of the aneurysm was atherosclerotic in 8, mycotic in 1, and aortitis in 1. The location of the aneurysm was infrarenal in 8, and suprarenal in 2 cases. Aneurysmectomy and Dacron Y-graft interposition in 8 cases, and lease with Teflon Y-graft were made. In another 1 case, long thoracoabdominal bypass surgery was made. The operative mortality was 30%[3cases]. The postoperative complications were respiratory complications[3cases], acute renal failure[2cases], bleeding[lease], mechanical ileus[ lease], and peritonitis[lease].

Background: Mycotic aortic aneurysms are rare and life-threatening. Unfortunately, no established guidelines exist for the treatment of patients with mycotic aortic aneurysms. The purpose of this study was to evaluate the midterm outcomes of the open repair of mycotic thoracic and thoracoabdominal aneurysms and suggest a therapeutic strategy. Methods: From 2006 to 2016, 19 patients underwent open repair for an aortic aneurysm. All infected tissue was extensively debrided and covered with soft tissue. We recorded the clinical findings, anatomic location of the aneurysm, bacteriology results, antibiotic therapy, morbidity, and mortality for these cases. Results: The median age was $62{\pm}7.2years$ (range, 16 to 78 years), 13 patients (68%) were men, and the mean aneurysm size was $44.5{\pm}4.9mm$. The mean time from onset of illness to surgery was $14.5{\pm}2.4days$. Aortic continuity was restored in situ with a Dacron prosthesis (79%), homograft (16%), or Gore-Tex graft (5%). Soft-tissue coverage of the prosthesis was performed in 8 patients. The mean follow-up time was $43.2{\pm}11.7months$. The early mortality rate was 10.5%, and the 5-year survival rate was $74.9%{\pm}11.5%$. Conclusion: This study showed acceptable early and midterm outcomes of open repair of mycotic aneurysms. We emphasize that aggressive intraoperative debridement with soft-tissue coverage results in a high rate of success in these high-risk patients.

A Case of thoraco-abdominal aortic aneurysm involving from the lower descending- thoracic aorta to bifurcation of abdominal aorta into both common iliac artery is presented in special view-point of its surgical technic and postoperative complication. Operative technic is the most popular method of Dr. De Bakey's shunt of Dacron which is bridging thoracic aorta to terminal abdominal aorta primarily as temporary shunt but after anastomosing the individual hranch of left Renal, Celiac, Sup. meseateric and right Renal artery to corresponding part of the Dacron tube, the Dacroa graft is fixed as permanent graft in stead of excised thoraco-abdominal aorta. The patient died of acute renal failure and increasing evidence of CNS damage due to respiratory acidosis on 6th postoperative day hut this report will he a good experience in respect of further progress of aortic surgery in Korea.

대동맥수술 후 발생하는 문합부 가성동맥류는 드문 합병증이다. 파열로 심한 출혈이 일어날 경우 치명적이므로 발견 즉시 교정을 해주어야 하는데 본원에서는 2명에서 3번에 걸친 대동맥문합부 가성동맥류를 수술적으로 치료하였으므로 그 과정을 보고하고자 한다. 첫 증례는 B형 만성 대동맥박리증이 있는 환자에서 복부대동맥류를 인조혈관으로 교정한 후에 대동맥문합부에 발생한 가성동맥류였는데 흉복부대동맥치환술로 문합부를 인조혈관끼리 연결 문합하여 치료하였다. 두 번째 증례는 파열 흉복부대동맥류에서 근위부 대동맥문합부에 발생한 가성동맥류로서 대동맥궁 치환술로 문합부를 인조혈관끼리 연결 문합하여 치료하였다. 그 후 이 증례에서는 다시 대동맥근부 문합부에 가성동맥류가 발생되어 재보강하는 이차 수술을 시행하였다. 두 증례 모두 별 합병증 없이 외래에서 경과 관찰 중이다.

We experienced 20 cases of acquired aortic diseases during last 1 year [Sep. 1992-Aug. 1993] with newly developed surgical strategies. There were 13 cases[65%] of aortic dissections, 5 cases[25%] of aortic aneurysms and 2 cases of Takayasu arteritis with mean age of 56 + 16 years[range:5-78].In ten cases of patients requiring ascending aortic replacement, femoral artery and femoral vein &/or RA auricle were used as cannulation site. With deep hypothermic circulatory arrest and retrograde cerebral perfusion of cold oxygenated blood via SVC, we can replace the ascending aorta and part of arch if necessary. The mean duration of circulatory arrest was 30 minutes[17-45 min]. In 5 cases of patients who requiring descending and thoracoabdominal aorta replacement, we used simple aortic crossclamping under normothermia with no heparin. The mean duration of aortic crossclamping was 37 minutes[25-50 min].The results of operation were as follow:Operative mortality[2 cases, 10%], delayed cerebral infarct[1], low extremity weakness[1] and intraoperative myocardial infarct[1]. There are no delayed complication or mortality as yet.

We report an unusual case of delayed bleeding after open surgical repair of a thoracoabdominal aortic aneurysm. A 79-year-old man developed a massive retroperitoneal hematoma 49 days after Crawford type III thoracoabdominal aorta replacement. During emergency surgery, a tear was found in the prosthetic vascular graft caused by a sharp bony spur arising from the second lumbar vertebral body. This rare, but potentially lethal, complication indicates that attention should be paid to sharp bony structures during open repair of the descending aorta.

1987년부터 1994년까지 서울대학교병원 흉부외과에서 흉복부 대동맥류의 진단하에 외과적 치료를 받은 환자는21명이었다. 이 환자들의 나이는20세부터 67세까지 다양하게 분포하였으며, 평균연령은 41.5세 였다. 남녀는 각각 11명, 10명이었다. 증상으로는 대부분의 환자들이 신체의 한 부분의 동통을 호소했는데, 배부동통이 가장 많았고, 흉통과 흉부의 불쾌감, 옆구리 동통 등도 호소했으며, 증상이 없었던 경우도 3례 있었다. 21례 중 15례(71.4%)가 만성 해리성 대동맥류였으며, 6례 (28.5%)가 진성 대동맥류였다. 만성 해리성 대동맥류 환자중 고혈압과 연관된 동맥경화증이 6례(28.5%)에서 관찰되었으며, Martian증후군이 5례 (2).8%)의 환자에서 확인되 었고, 2례 (9.5%)는 임신이 원 인으로 판단되 었다. 대동맥류의 크기는 6~12cm까지 다양했고, Crawford 분류에 따라 분류하면, Type I 이 7례 (33.3%), Type II가 8례 (38.1%)였고, Type R과 Type W가 각각 3례 (14.3%)씩 있었다. 한 예를 제외한 모든 환자에서 질환이 있는 부위의 대동맥을 인조혈관으로 치환하는 수술을 시행하였고, 한 예 에서만 가성동맥류로 인한 질환으로 진단되어 동맥벽의 열상\ulcorner위를 일차봉합하였다. 대동맥 교차차단시 근위부의 고혈압 및 그로인한 뇌척수액압 증가를 막고, 원위부의 허혈상태의 교정 및 척수허혈을 방지하고, 혈역학적 조절을 용이하게 하기위하여 우회술을 시행하였는데 21명의 환자 중, 12례(57.1%)에서는 대퇴동맥과 대퇴정맥, 또는 대퇴동맥과 폐동맥에 캐늘라를 상관하여 부분적 체 외순환을 시행하였고, 4례 (19.0%)에서는 Biopump를 좌심실심이와 대퇴동맥에 상관하여 우회술을 시행하였으며, 체와순환술과 일시적 완전순환정지를 이용한 예가 2례 (9.5%), Gott씨 도관을 이용한 단락술을 실시한 예가 1례 (4.7%) 있었으며, 우회술물 시행하지 않고 단순 대동맥 교차차단만으로 수술을 시행한 경우도 2례 (9.5%) 있었다. 수술후 발생한 합병증으로는 5례 (23.8%)에서 일측 성대신경 손상으로 인한 애성이 발생하였고, 창상감염이 4례(19.0%), 하반신 마비가 2례 (9.5%), 유미흉이 1례 (4.7%)에서 발생하였다. 병원사망율은 9.5%로 2례 있었고, 만기 사망례는 없었다. 결론적으로, 중요합병 증 발생율과 사망율이 비교적 낮았고, 외래 추적조사 결과 퇴원환자 모두 양호한 건강상태를 유지 하고 있었기에, 흉복부 대동맥류의 丙珦岵\ulcorner치료는 이제 더이상 고위첨도의 수술이 아니라고 여겨지며, 수술의 적응증이 되는 환자에게는 조기에 수술을 권유하는 것이 좋으리라 판단된다.

Due to its low prevalence and because there is lack of awareness about it, Loeys-Dietz syndrome is often misdiagnosed as Marfan syndrome, which has similar skeletal abnormalities and aortic pathology. However, the differential diagnosis between these two connective tissue diseases is critical because they correspond to different surgical indications and surgical decision-making. We report two cases of successful thoracoabdominal aortic replacement in patients with previously undiagnosed Loeys-Dietz syndrome.
