The treatment of aortic aneurysm of ascending aorta has been fraught with difficult surgical problems. For the most part, these were resolved in 1968 with the introduction of a technique of total replacement of ascending aorta and reimplantation of the coronary arteries by Bentall and De Bono. This technique however, with all of its advantages, caries a certain problems. In chronic dissecting aneurysms, there is frequently a marked disparity in circumference between the true and false lumen distally. Distal perfusion is directed into both the true and false lumens by removing segment of the septum between the two lumens and constructing the distal graft anastomosis is to the outer layer of aortic adventitia. The distal false lumen, aortic branches and fenestrations have matured and healed in most cases. And importantly, major aortic tributaries may be solely dependent on the false lumen for perfusion. We are presenting two cases of chronic dissecting aneurysm of ascending aorta with aortic regurgitation, who have good result by surgical correction of so-called Bentall procedure with maintenance of blood flow directed into both true and false lumen.

Ruptured aneurysms of the sinus of Valsalva are relatively rare, and the incidence seems to be higher in oriental than in western countries. Eight patients underwent operative treatment at Chonnam University Hospital from June, 1986 to May, 1992. Six of the patients were male and two female. Age ranged from eight to fifty six years. Associated cardiac lesions were common including AR and VSD in four patients respectively. Diagnosis was made by 2D-Echo and cine-angiogram. In six patients aneurysms of the sinus of valsalva ruptured from the right coronary sinus to the right ventricle and in two from right coronary sinus to the right atrium Direct closure of aneurysmal rupture and patch closure of VSD in four cases, resection of the aneurysm and direct closure in one case, direct closure of the fistula and AVR in two cases, direct closure in one case were performed. One patient combined with VSD, pulmonary hypertention and bacterial endocarditis underwent operation, but he died of sudden cardiac arrest the day after the operation. Operative results were relatively good in the other patients.

발살바동 동맥류는 매우 드문 질환으로 1987년부터 1994년까지 인제대학교 의과대학 서울백병원 흉부외과학교실에서는 총 12례를 경험하였으며 이는 이 기간중의 심폐체외순환을 이용한 심장수술중 0.7%였다. 남자가 8례, 여자가 4례였고, 연령분포는 8세에서 38세까지로 평균 19.2세 였다. 파열이 있었던 경우는 8례였다. 발살바동 동맥류의 기원은 우측 발살바동에서 10례(83.3%), noncoronary 발살바동에서 2례 (16.6%)였다. 파열된 경우에는 우측 발살바동에서 6례, noncoronary발살바동에서 2례였으며, 우측 발살바동에서 기원한 6례중 5례가 우심실로, 1례가 우심방 및 우심실로 파열됐고, noncoronary 발살바동에서 기원한 2례중 1례가 우심방으로, 1례가 우심실로 파열됐었다. 동반된 심질환은 심실중격결손이 10례(83.3%)였고 이중 9례는 우측 발살바동에서 동반되었으며, 대동맥 판폐쇄부전이 동반된 예는 3례로서 모두 심실중격결손도 같이 동반하고 있었다. 그외 승모판폐쇄부전이 1례, 우심실양분증이 1례였다. 조기사망은 없었고, 만기사망은 술후 15개월에서 1례있었는데 심내막염으로 인하여 사망하였다. 술후 평균 29개월(4~60개월)간의 추적기간 \ulcorner만기사망 1례를 제외한 11례에서 WYHA기능적 분류로 classs I의 상태이다. 수술의 위험도나 사망률이 낮으므로 합병증의 위험이 있으면 파열이 없더라도 수술하여야 하며, 파열이 있는 경우는 진단이 되면 바로 수술을 해야할 것으로 사료된다. 대부분의 경우 대동맥판막 및 동맥류의 정확한 판단 및 교정을 위해 대동맥절개가 필요하다. 한편 동반된 심질환도 동시에 교정해주며 특히 대동맥판막에 대해서는 철저히 교정 해주어야 한다고 생각한다.

Formation of an aneurysm in the sinus of Valsalva of the aortic root is usually due to an area of congenital weakness in its wall. This aneurysm may progressively dilate and rupture into any of the cardiac chambers or into the pericardial cavity. Though this is conventionally treated by surgery, interventional therapy using various closure devices is becoming more common. Embolization of these closure devices may occur. We report a case of embolization of such a device into the left pulmonary artery which during surgical retrieval, unmasked the hidden ventricular septal defect (VSD). Therefore one has to be cautious while making a diagnosis of rupture of the sinus of Valsalva of right coronary sinus without VSD.

To minimize the period of brain ischemia and the potential for neurologic damage during aortic arch replacement, we used the arch-first technique. First case was a 28-year-old female with extensive aneurysm involving ascending, arch and descending thoracic aorta. Exposure was obtained via a bilateral via a bilateral thoracotomy (clamshell incision) in the anterior 4th right and 3rd left intercostal space with oblique sternotomy. To prepare for arch perfusion, the side-arm graft(10mm) was anastomosed to the aortic graft, opposite the site of the planned anastomosis to the arch vessels. After completing the arch anastomosis under total circulatory arrest(37min) and retrograde cerebral perfusion(12min), aortic graft was clamped on either side and the arch was perfused via side-arm graft for 36min. When distal aortic anastomosis was finished, distal clamp of aortic graft was released and arch vessels were perfused via common femoral artery, and the proximal aortic anastomosis was accomplished. The patient was discharged with no event. Second case was a 48-year-old male with extensive aneurysm involving ascending, arch, and aortic regurgitaiton(grade III/IV). This case was also done using the clamshell incision. Aortic valve replacement was done by valved-conduit(Vascutek 30mm), both coronary artery anastomosis using Cabrol's procedure. Last operation procedure was the same as the 1st case.

Two cases of congenital aneurysm of sinus of Valsalva, ruptured into the right ventricle, and associated with ventricular septal defects, were undergone intracardiac repair with the aid of extracorporeal circulation using Bentley bubble oxygenator and moderate hypothermia. Case 1. A 20 year old male, with the chief complaints of palpitation and dyspnea, was admitted to Kyungpook National University Hospital on Dec. 16, 1976. Continuous machinery murmur was heard best at left 3rd. intercostal space along the sternal border. Retrograde aortography disclosed aneurysm of the right coronary cusp, which ruptured into the right ventricle. Utilizing cardiac bypass and moderate hypothermia, the right ventricle was opened and aneurysm was closed by direct sutures. Associated ventricuar septal defect was directly ,closed and suture line was reinforced by Dacron patch. Total bypass time was 112 minutes and total aortic cross clamping time was 37 minutes. Assist ventilation was carried out for 28 hours postoperatively. His postoperative course was smooth except removal o1 substernal hematoma and he was .discharged on 24th postoperative day. Case 2. A 28 year old man was admitted to our Hospital on June 9, 1976. two weeks prior to this admission, suddenly he had collapsed while he was walking on the street. Following `this episode, palpitation, dyspnea on exertion and frequent respiratory infection developed. Grade IV systolic murmur was heard best at 3rd intercostal space along the sternal border. Retrograde aortography confirmed the diagnosis of rupture of aneurysm of the sinus Valsalva ruptured into the right ventricle. Under the cardiopulmonary bypass the right ventricle was opened and ruptured aneurysm and infracristal ventricular septal defect were directly closed and reinforced with Dacron patch. Postoperative course was uneventful and he was discharged on 14th postoperative day. The pathogenesis of aneurysm of the sinus Valsalva and mode of diagnosis were discussed. Principle of surgical repair was presented.

The aneurysmal dilatation of ascending aorta with the aortic regurgitation presents typical surgical problems. Over the years, various surgical procedures had been used for the management of the dilated segment of sending aorta and the aortic regurgitation. The surgical technique Is still in the state of evolution. The one method is the super coronary replacement of the ascending aorta with vascular graft and replacement of the aortic valve with preservation of the coronary ostia as advocated by Miller and his colleague at Stanford University, so called conventional technique". The other is the replacement of aortic valve and the dilated segment of the ascending aorta using a composite graft and transplantation of the coronary ostia as described by Bentall and DeBono in 1968. The controversy appears to evolve around 3 technical problems. One is bleeding from the grafted area. Two is later development of the aneurysmal dilatation of the subcoronary aortic wall when non-composite graft is employed. Three is a management of the coronary arteries. The purpose of this article is to present our experience with 7 cases of annuloaortic ectasia in whom both of these surgical techniques at that employed and to review some of the problems that encountered during the management of these patients .
