A 21 years old male student was admitted because of mediastinal mass that was noticed in routine physical examination. He complained progressive hoarseness, mild dysphagia, and anterior chest pain on deep respiration. This mediastinal mass was diagnosed as aortic aneurysm involving ascending, transverse, and descending thoracic aorta with aid of aortogram. Total prosthetic replacement of aneurysm was performed successfully using extracorporeal circulation and hypothermia. For myocardial protection during aortic cross clamping, cardioplegic solution was used and topical myocardial cooling was also adapted For simplicity of cardiopulmonary bypass, Y-shaped connectors took cerebral perfusion catheters to the main perfusion line beyond the arterial pump. Total bypass time was 219 minutes, and aortic cross clamp time was 104 minutes. Recovery was uneventful except respiratory insufficiency for first 4 days. Isotope aortogram checked on post operative 30th day showed normal aortic configuration. He was discharged on post operative 35th day. A follow-up chest X-ray study 5 months later showed nearly normal anatomy.

True aneurysms of the coronary artery after aortic root replacement in Marfan syndrome patients are very rare. An anomalous origin of the right coronary artery (RCA) from the left sinus of Valsalva adds complexity during aortic root surgery. We present a case of a 37-year-old male patient with Marfan syndrome who had an RCA anomaly and a 4.5-cm true aneurysm of the common coronary button 14 years after a previous Bentall procedure. A redo Bentall operation and hemi-arch replacement were successfully performed. The anomalous origin of the RCA from the left sinus of Valsalva was safely divided and anastomosed as separate coronary buttons to the prosthetic composite valve graft. To prevent coronary button aneurysms after aortic root surgery in Marfan patients, the coronary buttons and the corresponding side holes on the prosthetic graft must be reduced to the maximum possible extent.

대동맥수술 후 대동맥질환의 재발은 주로 하부에 대동맥류의 형태로 나타나며 상부에 침투성 동맥경화성 궤양의 형태로 나타나는 것은 매우 드물다. 대동맥류 수술의 기왕력을 가진 환자에서 대동맥궁과 하행대동맥의 근위부에 걸쳐 발생한 침투성 동맥경화성 궤양의 파열을 완전순환정지 하에 인조혈관을 사용하여 패취봉합을 성공적으로 시행하였기에 문헌고찰과 함께 보고하는 바이다.

배경: 급성대동맥 박리증의 수술 시 궁부에 내막 파열이 있는 경우 본원에서는 파열 원위부까지 대동맥 박리부를 치환하여 수술해 왔다. 이의 임상 경험을 분석하여 그 결과를 알아보고자 이 연구를 시행하였다. 대상 뜻 방법: 1996년 3월부터 2002년 7월까지 본원에 Stanford A형 급성 대동맥 박리증으로 수술받은 사람 중 대동맥궁 근처에 내막파열이 있었던 환자 31명을 대상으로 후향성 조사를 시행하였다. 환자의 성비는 남자 12명, 여자 19명이었고 나이는 59.6$\pm$9.4세이었다. 수술은 18명에서는 반궁치환술(Hemiarch replacement)을 시행하였고 13명에서는 궁분지치환술(Arch branch replacement)을 시행하였다. 3명은 Clamshell incision을 28명은 정중흉골절개술을 시행하였다. 모든 환자에서 극저체온 순환정지하에서 원위부 문합과 궁부 치환을 시행하였다. 동반 수술은 Bentall 수술이 2예, axillobifemoral bypass 1예, femorofemoral bypass 1예 carotid a bypass가 1예 등이었다. 결과: 술 후 합병증은 급성신부전이 8예, 중추신경합병증이 3예, 저심박출증이 2예, 말초 순환 부전이 2예, 창상 감염이 2예 발생하였다. 사망은 술 후 30일 이내 원내 사망이 4명으로 사인은 급성신부전 1예, 출혈 1예, 저심박출증 1예 및 말초순환장애 수술 후 재관류 손상 1예였다. 술 후 30일 이후 원내 사망은 3예로 사인은 신부전 1예와 다장기 부전증 2예로 총 수술사망률은 22.5%였다. 퇴원 후 만기 사망은 4예로 사인은 뇌출혈 2예와 원위부 파열이 2예였는데 이 중 반궁치환술을 한 경우가 3예였다. 결론: 반궁치환술은 궁분지치환술보다 상대적으로 수술시간이 짧고 수술사망이 적으나, 만기 사망이 많았다. 궁분지치환술은 수술시간이 길고 사망률이 높은 수술이나 대동맥궁 분지부에 길이 파열된 경우 필요한 수술이므로 향후 더 연구가 필요하리라 생각한다

The frozen elephant trunk (FET) technique can be applied to extensive aortic pathology, including lesions in the aortic arch and proximal descending thoracic aorta. FET is useful for tear-oriented surgery in dissections, managing malperfusion syndrome, and promoting positive aortic remodeling. Despite these benefits, complications such as distal stent-induced new entry and spinal cord ischemia can pose serious problems with the FET technique. To prevent these complications, careful sizing and planning of the FET are crucial. Additionally, since the FET technique involves total arch replacement, meticulous surgical skills are essential, particularly for young surgeons. In this article, we propose several techniques to simplify surgical procedures, which may lead to better outcomes for patients with extensive aortic pathology. In the era of precision medicine, the next-generation FET device could facilitate the treatment of complex aortic diseases through a patient-tailored approach.

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.

원위부 대동맥궁에 발생한 대동맥류에 대한 수술을 위해서는 정중흉골 절개술 또는 측방개흉을 통한 수술방법이 있으나 문합 부위의 시야 확보가 용이하지 않은 경우가 자주 있다. 수술 대신 중재시술로 스텐트 그라프트를 삽입하는 방법 또한 가능하지만 동맥류보다 근위부에 충분한 고정 거리를 확보하기 위해서 대동맥궁 분지 일부를 결찰하고 우회로를 조성해야 할 필요가 있다는 제한이 있다. 저자들은 이들 방법의 장점을 취하고자 정중흉골절개술 후 완전 순환 정지 상태에서 대동맥궁을 치환하는 수술 중 외과적 문합 대신 스텐트 그라프트를 이용하여 인조혈관 원위부를 고정하는 방법을 취하여 양호한 결과를 얻은 경험을 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.

We present a case of intracranial aneurysm located in the P1 segment of left posterior cerebral artery in the context of tetralogy of Fallot. Complex variations included right aortic arch with abnormal branching. Also, the bilateral vertebral arteries were absent, with a type I persistent proatlantal intersegmental artery of the left side. The aneurysm was treated with endovascular intervention with a Tubridge flow diverter and was noted to be completely cured on 6-month follow-up. We discuss the many considerations in this patient including developmental and modern-era treatment.

Thoracic endovascular aortic repair has become a widespread alternative treatment option for thoracic aortic aneurysm. The debranching of arch vessels may be required to provide an acceptable landing zone for an endovascular stent graft. We report a case where the bypass graft used in the thoracic endovascular aortic repair procedure compressed the left internal jugular vein, causing acute thrombotic occlusion.
