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.

대동맥 박리증에 의한 관류부전은 진단상의 어려움을 야기할 뿐만 아니라 술 후 환자사망의 주요 원인으로 작용한다. 이러한 관류부전은 여러 가지 기전에 의해 나타나며, 이에 따른 적절한 치료방법의 선택이 환자예후에 중요한 영향을 미친다. 사지 관류부전의 경우 통상적으로 혈관 우회술이 주로 사용되어졌으나, 비침습적인 중재술이 하나의 좋은 치료방법으로 대두되고 있다. 저자들은 급성 대동맥 박리증에 의한 하지 관류부전 환자에서 대동맥치환술에 이은 스텐트 삽입술로 좋은 결과를 얻었기에 문헌과 함께 보고한다.

Successful thoracic endovascular repair for complicated Stanford type B acute aortic dissection in two patients is herein reported. The true lumen flow was immediately restored following stent graft deployment in the descending thoracic aorta with subsequent resolution of the distal malperfusion syndrome. One patient is doing well more than 15 months after surgery and another patient who was treated more recently is also doing well 7 months postoperatively.

대동맥 박리증과 동반된 주요 장기로의 관류부전은 침범되는 대동맥 분지에 따라 다양한 임상양상을 나타낼 수 있으며, 수술 전에 예상했던 경우는 적극적으로 치료할 수 있으나 수술 중이나 수술 후 발생한 경우에는 관류부전에 대한 의심을 하지 않고서는 환자의 이환율 및 사망률을 증가시키게 된다. 따라서 대동맥 박리증 수술 시에는 항시 이러한 관류부전에 대한 염두를 하고 치료에 임해야 하며 조기발견 및 적극적인 치료가 그 성적에 큰 영향을 미치게 된다. 저자들은 급성 대동맥 박리증 환자에서 뇌, 신장, 하지로의 관류부전이 동반된 4명의 환자에 대해 적극적인 치료로 좋은 성적을 얻었기에 문헌고찰과 함께 보고하는 바이다.

Background: Complicated acute type B aortic dissection is a life-threatening condition with high morbidity and mortality. The aim of this study was to report a single-center experience with endovascular stent-graft repair of acute type B dissection of the thoracic aorta and to evaluate the mid-term outcomes. Methods: We reviewed 18 patients treated for complicated acute type B aortic dissection by thoracic endovascular aortic repair (TEVAR) from September 2011 to July 2017. The indications for surgery included rupture, impending rupture, limb ischemia, visceral malperfusion, and paraplegia. The median follow-up was 34.50 months (range, 12-80 months). Results: The median interval from aortic dissection to TEVAR was 5.50 days (range, 0-32 days). There was no in-hospital mortality. All cases of malperfusion improved except for 1 patient. The morbidities included endoleak in 2 patients (11.1%), stroke in 3 patients (16.7%), pneumonia in 2 patients (11.1%), transient ischemia of the left arm in 1 patient (5.6%), and temporary visceral ischemia in 1 patient (5.6%). Postoperative computed tomography angiography at 1 year showed complete thrombosis of the false lumen in 15 patients (83.3%). Conclusion: TEVAR of complicated type B aortic dissection with a stent-graft was effective, with a low morbidity and mortality rate.

Aortic dissection caused by blunt trauma is a rare injury that can be complicated by malperfusion syndrome resulting from obstruction of branch vessels of the aorta. Here, we present a case of traumatic type B aortic dissection with right renal and small bowel ischemia, successfully managed by endovascular fenestration.

A 49-year-old man with drowsy mentality was diagnosed with acute type A aortic dissection; he underwent an emergency operation. When selective antegrade cerebral perfusion was initiated, the right regional cerebral oxygen saturation ($rSO_2$) decreased as compared to the left one. Adequate blood flow was perfused through the branch of the artificial graft, after distal anastomosis, but the right $rSO_2$ did not recover. Angiography revealed another intimal tear on the right common carotid artery. A stent was then inserted. The right $rSO_2$ promptly increased to the same level as that of the left one. The patient was discharged without any neurologic complications.

Complex lesions of the thoracic aorta are traditionally treated in 2 surgical steps with the elephant trunk technique. A relatively new approach is the frozen elephant trunk (FET) technique, which potentially allows combined lesions of the thoracic aorta to be treated in a 1-stage procedure combining endovascular treatment with conventional surgery using a hybrid prosthesis. These are very complex and time-consuming operations, and good results can be obtained only if appropriate strategies for myocardial, cerebral, and visceral protection are adopted. However, the FET technique is associated with a non-negligible incidence of spinal cord injury, due to the extensive coverage of the descending aorta with the excessive sacrifice of intercostal arteries. The indications for the FET technique include chronic thoracic aortic dissection, acute or chronic type B dissection when endovascular treatment is contraindicated, chronic aneurysm of the thoracic aorta, and chronic aneurysm of the distal arch. The F ET technique is also indicated in acute type A aortic dissection, especially when the tear is localized in the aortic arch; in cases of distal malperfusion; and in young patients. In light of the great interest in the FET technique, the Vascular Domain of the European Association for cardio-thoracic Surgery published a position paper reporting the current knowledge and the state of the art of the FET technique. Herein, we describe the surgical techniques involved in the FET technique and we report our experience with the F ET technique for the treatment of complex aortic disease of the thoracic aorta.

좌심실 유출로 협착을 동반한 좌심실 점액종은 점액종 색전에 의한 뇌경색, 심근경색 등의 치명적인 합병증을 유발할 수도 있고 돌연사의 위험성도 있어 진단되면 조기에 외과적으로 적출하는 것이 바람직하다. NYHA II의 운동성 호흡곤란을 주소로 내원한 18세 남자 환자가 경흉부 초음파상 심 수축기에 좌심실 유출로를 협착하는 $4{\times}3\;cm^2$ 크기의 좌심실내 종양이 발견되어 좌심실 절개를 통한 적출술을 받았다. 술 후 점액종으로 확진되었으며 환자는 10일째에 합병증 없이 퇴원하였다. 현 22개월째 외래 추적관찰 중인데 이학적 소견이나 심초음파 검사상에서 특이 사항은 관찰되지 않고 있다.

Background: The axillary artery is frequently used for cardiopulmonary bypass, especially in acute aortic dissection. We have cannulated the axillary artery using a side graft or by directly using Seldinger's technique. The purpose of this study was to assess the technical problems and complications of both cannulation techniques. Materials and Methods: From January 2003 to December 2009, 53 patients underwent operations using the axillary artery for arterial cannulation. The axillary artery was cannulated with a side graft in 35 patients (side graft group) and directly using Seldinger's technique in 18 patients (direct group). Results: The results were compared between two groups, focusing on cannulation-related morbidities including neurologic morbidity. Arterial damage or dissection of the axillary artery occurred in 1 (2.9%) patient in the side graft group and in 1 (5.6%) patient in the direct group. Malperfusion and insufficient flow did not occur in either group. There were no postoperative complications related to axillary cannulation, such as brachial plexus injury, compartment syndrome, or local wound infection, in either group. Conclusion: Technical problems and complications of the axillary arterial cannulation in both techniques were rare. Direct arterial cannulation using Seldinger's technique was done safely and more simply than the previous technique. It was concluded that both axillary arterial cannulation techniques are acceptable and it remains the surgeon's preference which technique should be used.
