Thoracic endovascular aortic repair (TEVAR) has emerged as an effective therapy for a variety of thoracic aortic pathologies. However, various types of endoleak remain a major concern, and its treatment is often challenging. We report a case of type I endoleak occurring 19 months after zone II hybrid TEVAR. The endoleak was successfully repaired by the frozen elephant trunk technique, without removal of a previous stent graft, combined with ascending aorta and total arch replacement.

For high-risk patients, endovascular aortic aneurysm repair (EVAR) is a good option but may lead to serious complications, which should be addressed immediately. A 75-year-old man with a history of abdominal surgery underwent EVAR for an aneurysm of the abdominal aorta and iliac arteries. During EVAR, iliac artery rupture and graft limb occlusion occurred, and they were successfully managed by the additional deployment of an iliac stent graft and balloon thrombectomy, respectively. We, herein, report a rare case of the simultaneous development of the two fatal complications treated by the endovascular technique.

Forty three patients with disease of the aorta were admitted in this department during the period from beginning of 1956 to the end of 1976. They consisted of eighteen cases of aortic aneurysms, eight cases of Takayasu's arteritis, eight Leriche syndromes, six dissecting aneurysms, two aortic coarctations and one case of vascular ring. Of eighteen aortic aneurysms, twelve were operated resulting in eight survivors. Three of four mortalities were in shock preoperatively because of aneurysmal rupture. Among six dissecting aortic aneurysms, four were type III and two were type I according to DeBakey's classification. For the purpose of relief of acute arterial insufficiency in the lower extremities, a re-entry operation grafting a Y-shaped dacron vessel between abdominal aorta and common iliac arteries was performed. The patient regained consciousness soon after the operation and was well until postoperative second day, when severe convulsion developed abruptly and died. And in a chronic case of type III dissecting aneurysm, a dacron graft bypass shunt between ascending aorta and lower descending thoracic aorta with resection of the aneurysm was performed, but acute severe aortic insufficiency developed soon after the operation and fell into intractable heart failure resulting in death. The cause of the aortic insufficiency seems to be retrograde dissection from the proximal anastomosis site in the ascending aorta. Three cases were treated medically with Wheat's regimen. Two of them survived with relief of symptoms. Eight patients of Takayasu's arteritis were all females and aged between twenty and forty-four averaging twenty nine. Bypass graft operation between aortic arch and carotid arteries using Y-shaped nylon prostheses were performed in three patients resulting in death in two cases postoperatively due to severe cerebral arterial insufficiency during the procedure. All the patients with Leriche syndrome were males and over forty. In two cases, bypass graft with Y-shaped dacron vessel between terminal aorta and common iliac or femoral arteries were performed with good result. Thromboembolectomy or thromboendarterectomy was employed in three patients, of whom one was aggravated in sexual problem postoperatively. One out of two aortic coarctations and a vascular ring were treated surgically with excellent results.

배경: 동종이형의 심장이식 후에 나타나는 만성 거부반응은 수술 후 약 6개월이 지나 나타나며, 이로 인해 이식된 심장의 관상동맥의 동맥 경화 소견과 심장의 손상을 일으키는 혈관병증이 나타나는 바, 대혈관인 대동맥에서도 이러한 소견을 보이는 지를 확인하고자 하였다. 대상 및 방법: $200{\sim}300gm$의 백서(Spraque-Dawley Rat)에서 이소성의 동종이형의 심장이식(heterotopic heart alto-transplantation)을 Ono-Lindsey method로 시행한 후 사이클로스포린(cyclosporin A 10mg/kg/day, 종근당 제공)을 투여하여 3개월 이상 생존한 군에서 동물을 희생시킨 후 자가 상행 대동맥과 이식된 심장의 대동맥에서 각각 조직 절편을 얻어 조직 검사를 시행하여 비교하였다. 자가 상행 대동맥의 조직 검사(N=9, native ascending aorta)와 동종 이형의 이식된 심장의 대동맥(N=13, alto-transplanted aorta)의 조직 검사를 동종이형의 심장이식 후의 만성 거부 반응의 특징적인 조직 검사 소견인 1) 내막 비후(intimal thickening), 2) 중층 비후(medial hyperplasia), 3) 중층 석회화(medial calcification), 4) 중층 염증(medial inflammation), 5) 연골 화생(chondroid metaplasia)에 대하여 한 명의 병리의에 의해 대조군과 이식군에서 각각 심한 정도를 통계처리(Mann-Whitney Test, SPSS version 12.0 Windows)하여 비교하였다. 결과: 중층 비후 외(p=0.36)에 내막 비후(p<0.0001), 중층 석회화(p=0.045), 중층 염증(p<0.0001), 연골 화생(p=0.045)에 있어 이식된 심장의 대동맥에서 의미 있는 변화를 보였다. 결론: 동종 이형의 심장 이식 후에 만성 거부 반응에 의한 혈관병증(cardiac allograft vasculopathy)은 관상 동맥을 침범하여 심근의 손상을 가져오며, 이와 같은 만성 거부 반응에 의한 혈관 병증의 변화는 대혈관인 이식된 대동맥에서도 상기의 결과와 같이 나타나 대동맥에서도 만성적인 거부 반응이 진행되고 있음을 확인할 수 있었다.

생후 85일 된 대동맥궁 단절이 동반된 총동맥간 환자에서 완전순환정지 없이 1차 완전 교정술을 성공적으로 시행하였다. 대동맥 단절 교정은 국소순환하에 상행 및 하행대동맥을 문합하였고 우심실유출로 재건은 Shelhigh 판막도관을 이용하였다. 술 후 혈관에 의해 일시적으로 좌측 기관지가 눌리는 합병증이 발생하였으나 자세변화와 흉부물리치료로 호전되었다. 술 후 13개월 뒤에 판막도관의 협착으로 우심실 유출로에 대한 재수술이 필요했으며 환아는 현재 건강한 상태로 첫 교정술 후 14개월째 외래 추적중이다.

심방 중격 결손에 대한 경피적 카테타 폐쇄술은 적절한 환자에서 치료적 대안으로 이용되며, 미용적으로 우수하고, 덜 침습적이며, 재원 기간이 짧으나, 응급 수술이 요구되는 치명적인 합병증이 발생할 수 있다. 저자들은 Amplatzer septal occluder에 의한 심방 중격 결손의 경피적 카테터 폐쇄술 시행 후 발생한 대동맥-우심방루를 경험하였다. 시술 2개월 후에 호흡곤란, 심계항진과 용혈에 의한 황달로 발견되어, 대동맥의 무관상동맥동과 우심방 사이의 누공을 일차 봉합하고, 심방 중격 결손은 팻취로 봉합하는 응급수술을 시행하였다. 이 합병증은 우심방 원반(disk)이 대동맥으로 침식(erosion)하여 발생하였다.

We experienced a case of infective endocarditis of aortic valve and tricuspid valve associated with a fistula between aorta and right ventricle. The patient was 35 years old woman and showed severe congestive heart failure. Large and multiple vagetations were found on the valvular surfaces and a fistula was present between aorta and right ventricle. Probably infective endocarditis of aortic valve resulted in annular abscess and as it healed, a fistula was formed and tricuspid valve endocarditis followed. We replaced the aortic valve and tricuspid valve with St. Jude mechanical prostheses, and closed the fistula opening with suture. The postoperative course was smooth and the patient has no problems till now 4 months after operation.

광범위한 대동맥류의 수술은 주로 elephant trunk 술식을 이용한 단계적인 수술로 이루어 지고 있다. 그러나 elephant trunk 술식을 적용하기 힘든 경우 동시 치환을 고려하여야 한다. 과거 급성 대동맥박리로 상행대동맥 수술을 받은 과거력이 있는, 마르팡 증후군이 의심되는 35세 환자에서 대동맥 근위부의 대동맥류 및 하행대동맥류 파열이 발생하여 대동맥 판막에서부터 횡격막에까지 전 흉부대동맥 동시치환술을 성공적으로 시행하였기에 문헌 고찰과 함께 보고한다.

Rupture of the aorta following blunt trauma of the thorax may occur more frequently than has generally been recognized. Actual complete transection of the aorta usually results in immediate death but varying degrees of lesser disruption permit increased chance of survival. Chronic traumatic aneurysms are so designated following a period of 3 months from the traumatic incident. The exact time required for the acute process and hematoma to convert into an aneurysm is unknown. Because a thoracic surgeon encounters so few of these aneurysms, it is difficult for him to arrive at sound dicta of management from his personal experience. It is not surprising that controversy exists concerning the therapeutic approach to the aneurysm which is asymptomatic and is discovered months or years after the causative injury. In the hope of improving the surgical treatment of patients with this condition, we reported one case with chronic traumatic aneurysm of the descending thoracic aorta.

Abdominal aortic occlusion (AAO) caused by detachment of cardiac myxoma (CM) is a very rare complication in patients with CM. Although the nature of CMs has been well established, detachment of CM may cause unexpected serious complications such as vicious embolic events. Actually, in several cases of AAO caused by detachment of CM, it has been reported that CM fragments easily migrated to the brain, heart, and lungs, and caused lifelong neurological complications despite appropriate surgical therapy. Herein, we report a case of a patient with AAO caused by detachment of CM who underwent CM excision and abdominal aortic thromboembolectomy. Additionally, we have presented the preoperative and postoperative images using 64-multidetector computed tomography.
