Takayasu’s disease produces the occlusive and aneurysmal lesions of major branches of the aorta. Angiography is the most important diagnostic procedure in Takayasu’s disease. Surgical treatment is often justified to avoid the possible lethal consequences of hypertension on the heart, kidney, and brain, as well as in the case of aneurysm because of its risk of rupture. We experienced one case of the Takayasu’s disease associated with abdominal coarctation and renovascular hypertension. The patient was 17 years old female and had suffered from hypertension for 14 months. On physical examination, BP was 150/100 mmHg in the right arm and 120/80 mmHg in the left arm. The pulses of the left brachial and femoral arteries were weakly palpable. Aortogram showed the stenosis of the left common and subclavian arteries, coarctation of the abdominal aorta, and stenosis of the right renal artery and complete occlusion of the left renal artery. The stenosis of the right renal artery and the occlusion of the left renal artery produced the renovascular hypertension. She underwent aorta-aortic bypass for the coarctation of the abdominal aorta and aorta-renal bypass for treatment of renovascular hypertension Postoperatively, both femoral pulses were equally palpable. On discharge, antihypertensive drugs were discontinued. She has remained normotensive for last one year.

Aortic dissection is a serious disease that mortality does not approach to zero despite of medical and surgical improvement. Recently two cases of aortic dissection were treated with good results by the two other methods. Case 1 [57-Y-0-Male]; Chief complaint was chest pain radiating to the back. Preoperatively he was controlled by Minipress, dichlotride, & sodium nitroprusside. Aortography showed DeBakey Type III aortic dissection extending from just below the Lt. subclavian artery to the proximal portion of the origin of the renal artery. Through the midline long incision Flow reversal & Thrombo-exclusion method was used, and bypass course was proximal anastomosis at the ascending aorta - through the Rt. thoracic cavity - midportion of the diaphragm - posterior to the liver, stomach, & pancreas - distal anastomosis at the abdominal aorta proximal to its bifurcation. Bypass graft was preclotted 20 mm Dacron Woven Graft, and the aortic arch between the Lt. subclavian artery & Lt. common carotid artery was divided and meticulously sutured. Control aortogram which was done at 4th postoperative month revealed obstruction of the false lumen by thrombosis, and complications were not noticed. Case 2 [53-Y-0-Male]; Chief complaint was chest pain radiating to the abdomen. DeBakey Type III aortic dissection which was similar to the case 1 was detected by the aortography, and involvement of the Lt. subclavian & common carotid arteries was suspicious. Through the Lt. posterolateral thoracotomy the Ringed Intraluminal Sutureless Graft, No. 22 mm, was inserted from just below the Lt. common carotid artery to the midportion of the descending thoracic aorta under total circulation arrest using a F-F bypass, and the Lt. subclavian artery was ligated. Postoperatively hospital course was uneventful with antihypertensive drugs, and any specific complications were not noticed.

Objective : Cerebral aneurysm (CA) is an important acquired cerebrovascular disease that can cause catastrophic results. MicroRNAs (miRNAs) are small non-coding RNAs, playing essential roles in modulating basic physiologic and pathological processes. Currently, evidences have been established about biologic relationship between miRNAs and abdominal aortic aneurysms. However, biologic roles of miRNAs in CA formation have not been explained yet. We employed microarray analysis to detect and compare miRNA expression profiles in late stage of CA in rat model. Methods : Twenty-six, 7-week-old male Sprague-Dawley rats underwent a CA induction procedure. The control animals (n=11) were fed a normal diet, and the experimental animals (n=26) were fed a normal diet with 1% normal saline for 3 months. Then, the rats were sacrificed, their cerebral arteries were dissected, and the five regions of aneurysmal dilation on the left posterior communicating artery were cut for miRNA microarrays analysis. Six miRNAs (miRNA-1, miRNA-223, miRNA-24-1-5p, miRNA-551b, miRNA-433, and miRNA-489) were randomly chosen for validation using real-time quantitative PCR. Results : Among a set of differentially expressed miRNAs, 14 miRNAs were over-expressed more than 200% and 6 miRNAs were down-expressed lower than 50% in the CA tissues. Conclusion : The results show that miRNAs might take part in CA formation probably by affecting multiple target genes and signaling pathways. Further investigations to identify the exact roles of these miRNAs in CA formation are required.

From 1968 through September 1986, the authors have experienced 34 cases of peripheral arterial surgery using various vascular grafts. Almost all patients [32] were men, and age distribution was variable according to the disease entities. There were twenty eight cases of chronic occlusive peripheral vascular disease including ASO [21], Buerger`s disease [6], Aortoenteric fistula complicating infrarenal abdominal aortic aneurysm [1], four cases of vascular trauma, one case of acute arterial embolism [1] and one case of unknown etiology. The indications of operations for chronic vascular disease was intermittent claudication in 48%, rest pain in 45%, ischemic pregangrene or gangrene in 28%, and sensory change in 10% of patients. Types of operation used were arterial bypass in 28 cases [Aortobifemoral in 5, Aortoiliac in 3, Aortofemoral in 4, Aortoiliac with Aortofemoral in 1, Femorofemoral in 1, Femoropopliteal in 8, Femoroperoneal in 2, Axillofemoral in 3 cases of patients], graft interposition in four and patch angioplasty in three cases. Thirty four prosthetic vascular grafts including Dacron, Gore-Tex, Nylon and two autogenous saphenous vein graft and patch were used for vascular reconstruction in thirty four patients. Unfortunately recently performed one vein bypass was failed immediate postoperatively due to severity of disease and poor case selection. The authors experienced five post operative complications: wound infection [1], graft infection [1], bleeding [1], great saphenous neuralgia [1], pseudoaneurysm [1]. Twenty two of thirty four patients were followed up for more than one month and their cumulative patency rate was 81% [17/22] at 1 month and, 31% [7/22] at 5 month.

본 증례는 와파린을 복용하던 72세 여자가 기침을 심하게 하던 중 하복부 통증과 압통을 보이는 복부 팽만이 발생하여 복부 전산화단층촬영을 통해 복직근초 혈종을 진단한 경우이다. 복직근초 혈종은 매우 드물지만 항응고제를 복용하는 고령 환자나 분만을 했거나 복부 수술을 받은 경우 등에서 발생할 수 있고, 드물게 기침에 의해서도 발생할 수 있다. 따라서 이런 환자에서 심한 복통이나 복부 종물이 관찰되는 경우 그 가능성을 한 번쯤 생각해보아야 하겠다. 전산화단층촬영은 복직근초 혈종 진단의 특이성과 민감도가 높아 진단에 도움이 되며 대부분은 보존적인 치료만으로 회복되므로 본 질환의 위험인자와 진단방법에 대해 숙지하고 정확한 진단을 하는 것이 무엇보다도 중요하겠다.

One hundred and seventy-four patients were treated in this Department since 1956. One hundred and fifteen patients of them were surgically treated. They were classified on the basis of the disease entity as follows; 48 case of thrombo-angiitis obliterance, 8 cases of Leriche syndrome, 12 cases of arterial embolism, 36 arterial aneurysm, 5 arterio-venous fistula, 15 arterial and venous injuries, 8 pulseless diseases, 2 coarctation of aortas, 15 varicose veins, 12 thrombophlebitis, 9 superior venacaval syndromes, 2 inferior vena caval obstructions and Raynaud's diseases. All the cases of the Burger's diseases were males, and half of them were in the fourth decades, 39 cases underwent undergone unilateral or bilateral sympathectomies. All the Leriche syndromes were males aged over fifty. Three cases out of six were suffering from diabetes mellitus. 2 cases underwent aorto-femoral bypass graft with Y-shaped dacrons. And two embolectomies were performed in 2 cases. Eight cases of arterial embolisms among 12 had mitral valvular diseases with auricular fibrillation The most common site of lodgement of emboli was femoral artery. Nine out of 14 underwent embolectomies with Fogarty catheters. There were 14 peripheral arterial aneurysms, 16 thoracic and/or abdominal aortic aneurysms, and 4 dissecting aneurysms. Most frequent cause of peripheral arterial aneurysms were external trauma. Thoracic and abdominal aortic aneurysms were non-traumatic. And four cases of the dissecting aneurysms had significant hypertension and aged over fifty. Among 5 cases of arteriovenous fistulas, 2 cases hand typical Branham's sign, and they were normalized after operation. Eight cases of pulseless disease were females and aged from three to twenty-five. Three out of them were treated surgically using dacron prosthetic grafts, but the results of the surgery were variable and not satisfactory. A case of coarctation of aorta was treated surgically with an excellent result. Fourteen out of 15 varicose veins underwent ligation of the saphenous vein system, exstirpation of the varicose veins, stripping or some combination of these methods. Two cases of superior vena caval syndromes were operated by bypass graft between the left innominate vein and the right auricle. Two cases of inferior vena caval obstructions were operated upon through right atrial route using extracorporial circulation. All the four cases of vena caval obstructions showed excellent results postoperatively. Two cases out of 12 thrombophlebitis underwent thrombectomies. One of two Raynaud's diseases was surgically treated with an excellent result.

배경: 급성 type A 대동맥 박리에서 내막 파열의 위치는 다양할 수 있다. 본 연구에서는 내막 파열의 위치에 따른 수술 성적을 분석하였다. 대상 및 방법: 1995년 1월부터 2003년 5월까지 급성 type A 대동맥 박리로 수술받은 18명의 환자에서 내막 파열이 상행대동맥에 존재했던 경우(Group I, 11명)와 대동맥궁이나 하행대동맥에 위치하거나 대동맥 벽 내 혈종 (intramural hematoma)만이 있었던 경우(Group II, 7명)로 나누어 술 전, 술 중 소견, 수술 방법, 합병증, 사망 원인을 후향적으로 분석하였다. 결과: 수술 시간, 체외순환 시간, 대동맥 차단 시간 및 순환 정지 시간은 Group I에서 각각 381.5$\pm$81.0분, 223.5$\pm$42.5분, 146.4$\pm$34.8 분, 36.5$\pm$17.4분이었고, Group II에서는 각각 461.7$\pm$54.0분, 252.5$\pm$45.3분, 162.5$\pm$45.3분, 47.0$\pm$14.4분으로 Group II에서 더 길었다. 전체적으로 5명이 사망하여 27.8%(5/18)의 사망률을 나타냈으며 Group I에서는 9.1% (1/11), Group II에서는 57.1% (4/7)로 Group II에서 통계적으로 유의하게 높았다(p=0.003). 사망 원인으로는 출혈이 Group I에서 1명, Group II에서 2명, 저심박출 및 다발성 장기 기능 부전 1명, 술 후 복부대동맥 파열 1명이었다. 결론: 내막 파열이 상행 대동맥에 존재하는 type A 대동맥 박리에서의 수술 사망률은 크게 높지 않으나 내막 파열이 대동맥궁부 또는 하행대동맥에 위치했을 때 상행대동맥만을 대치한 경우 아직 높은 사망률을 나타내고 있다. 따라서 향후 수술 성적의 향상을 위해서는 내막 파열 부위를 수술 범위에 포함시키는 노력이 필요할 것으로 생각한다.
