Bentall`s operation for repair of annuloaortic ectasia has been associated with postoperative bleeding and with false aneurysm of the anastomotic site between the coronary orifice and composite graft.Among 5 cases, 2 cases have been operated direct anastomosis between coronary artery and vascular graft.Remained 3 cases have been operated with doughnutlike Teflon felt buttress.The technique of sandwiching the freed button of aortic wall bearing the coronary artery ostium between an outer Teflon felt doughnutlike buttress and the inner composite graft provides a leak-proof anastomosis.We experienced one case reoperation for bleeding at coronary anastomotic site above method.

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.

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.

The surgical treatment of annuloaortic ectasia falls into two basic categories, depending on the management of the coronary artery ostia and the sinus of Valsalva. The conventional method, first suggested by Groves, Wheat and their associates, employs a supracoronary graft for the treatment of aneurysm and conventional valve replacement. A more radical approach, that of Bentall and DeBono, uses a valve conduit from the aortic annulus to the distal extent of the aneurysm. This latter technique requires reimplantation of the coronary artery ostia for reestablishment of coronary artery blood flow. Recently we experienced a case of annuloaortic ectasia to which we applied the Bentall operation with the good postoperative result, and now we report this with literature review.

급성 대동맥 박리증에는 주요 장기의 관류 부전이 동반될 수 있으며 이는 사망의 중요한 원인이다. 관류 부전은 수술 전뿐 아니라 수술 중 및 수술 후에도 발생할 수 있고 침범하는 대동맥 분지의 위치에 따라 다양한 양상으로 나타난다. 이를 성공적으로 치료하기 위해서는 급성 대동맥 박리증 환자의 진료시 항상 관류 부전 합병 가능성을 염두에 두고 적절한 진단 및 치료 조치를 신속하게 진행하는 것이 가상 중요하다. 저자들은 급성 대동맥 박리증에 뇌, 하지, 신장 및 위장관 등 다양한 장기의 관류 부전이 합병한 환자 4명을 성공적으로 치험하였기에 보고한다.

From February 1985 to February 1993, 18 operations were performed in 17 patients for treatment of aneurysmal disease [n=12] and/or dissection of the ascending aorta [n=6]. The ages ranged from 26 to 69 years [mean 44.3 $\pm$ 11.0 years].The proposed operations include composite graft replacement of aortic valve and ascending aorta with coronary reimplantation in 11, graft replacement of ascending aorta alone in 5, aortic valve replacement and supracoronary graft replacement in 1 and ascending aorta to abdominal aorta bypass with thromboexclusion of descending aorta in one patient. Both Bentall [n=6] and Cabrol [n=5] technique were utilized for reimplantation of coronary arteries.Concomitant replacement of aortic arch and arch vessel reconstruction was necessary in two patients. Hypothermic circulatory arrest was utilized in 6 patients. Recently, four patients were managed on warm blood continuous cardioplegia via retrograde route. There were no operative deaths. No significant postoperative complications were noted. Postoperative follow up was complete in 15 patients from 1 month to 72 months. Redo operation was necessary in one patient who had suffered from distal recurrence of dissection 5 years after successful Bentall operation. The other patients are all in excellent clinical condition. From our early experience with those 17 cases, we assume that satisfactory operative result could be achieved with a variety of surgical technique including hypothermic circulatory arrest. In addition, continuous perfusion of warm blood cardioplegia via retrograde route is supposed to be beneficial in selected cases.

서울 대학교 병원 흉부외과에서 1981년부터 1996년 6월까지 65명의 환자에서 대동맥근부 치환술을 시행하였다. 해당 질환은 대동맥판륜 확장증이 31예(47.7%)로 가장 많은 빈도를 차지하였으며, 대동맥판륜 확장증을 동반한 Stanford type A 대동맥 박리증이 28예(43.1%), 대동맥 판막 폐쇄부전증을 동반한 상행대동맥류가 4예(6.2%), 그리고 대동맥 판막 치환술 후 재발성 심내막염에 의한 치환 판막의 열개와 Behcet씨 질환 환자에서의 대동맥 판막 치환술 후 치환 판막의 열개에 의한 판막주위 누출이 각각 1예씩 이었다. Martian증후군은 34명(52.3%)의 환자에서 동반되었다. 수술은 전형적인 Bentall 수술이 3예(4.6%), Cabrol 변형의 Bentall 수술 (Cabrol 수술)이 58예(89.2%)이었으며, 대동맥판막 보존술이 2예이었고, 2예에서 동종이식편을 이용하여 대동 맥근부 치환술이 시행되었다. 수술직후 3명의 환자가 사망(4.6%)하였으며, 수술 후 합병증은 19명(29.2%)의 환자에서 발생하였으나, 대부분 일시적인 합병증이었다. 수술직후 사망한 3명의 환자를 제외한 62명의 환자에서 평균 60.2$\pm$42.4 개월간 추적 관찰하였다. 7명의 환자(11.3%)가 추적기간 중 사 좡臼느만\ulcorner 12명의 환자 (19.4%)에서 잔여 대동맥의 동맥류성 변화가 발견되었다. 10년 생존율은 72.0$\pm$9.7%이었으며, 추후대동맥수 술의 10년 See-rate는 68.0$\pm$8.9%이었다. 다변수 분석을 통한 위험요소 분석에서 Martian 증후군, 응급 수술, 대동맥 박리증, 대동맥궁 치환술이 동반된 경우, 완전 순환정지를 시행했던 경우에서 수술 사망률 및 추후 대동맥수술의 가능성이 높은 것으로 나타났으며, 60세 이상의 고령이 만기 사망률의 위험요소로 분석되었다. 대동맥근부 치환술(주로 Cabrol 방법에 의한)은 다양한 대동맥근부 질환에 성공적으로 사용될 수 있으며, 대동맥판막 보존술과 동종이식 편을 이용한 치환술의 장기 결과에 대해서는 앞으로 지속적인 추적 결과가 필 요할 것으로 보인다. 또한 대동맥박리증 환자와 Marfan 증후군이 동반된 환자에서 잔여 대동맥의 동맥류성 변화에 대한 정기적인 추적 검사가 요구된다.

A case of Annuloaortic Ectasia associated with Marfan syndrome and mitral regurgitation is treated surgically by Bentall`s method and mitral annuloplasty. The Annuloaortic Ectasia is frequently accompanied with Marfan syndrome, its definition is simply explained as the following; the marked dilatation of the sinuses of Valsalva and the aortic annulus as well as the huge aneurysm of the ascending aorta. As the operative finding, the intimal tearing was shown as circular and the both coronary ostia were changed the position into high up. The patient was taken a corrective operation replacing the ascending aorta and aortic valve with a composite graft[St. Jude medical valve 29mm, woven Dacron tubular graft 31mm]. The both coronary ostia were reimplanted on the graft with 4-0 prolene by continuous suture. Mitral annuloplasty was performed. After the operation, the patient developed both spontaneous pneumothorax, he improved state by the closed thoracostomy. He has been doing well, postoperatively.

Between April, 1986 and July, 1991, 477 patients underwent open heart surgery with hypothermic cardiopulmonary bypass. There were 242 patients [50.7%] of acyanotic congenital anomalies, 34 patients [7.1%] of cyanotic congenital anomalies, and 187 patients [39.2%] of acquired heart diseases, 8 patients [1.7%] of coronary artery diseases, and 6 patients [1.3%] of mixed anomalies. Among the 276 congenital cardiac anomalies, 147 patients [53.3%] were male and 129 patients [46.7%] were female, ranged in age from 2 years to 58 years. Among the 187 acquired heart diseases, 72 patients [38.5%] were male and 115 patients [61.5%] were female, ranged in age from 10 years to 68 years. The common congenital defect were VSD and ASD in acyanotic cardiac patients, and TOF in cyanotic cardiac patients. Among the 187 acquired heart diseases, 180 patients underwent operation for cardiac valvular diseases, 4 patients were resected left atrial myxoma, and 3 patients underwent operation for aortic regurgitation with ascending aortic aneurysm. The operative mortality rate was 1.2% in acyanotic cardiac patients, 11.8% in cyanotic cardiac patients, and 6.9% in acquired cardiac patients, with overall mortality rate 4.2%.
