Type II chronic dissecting thoracoabdominal aortic aneurysms are a surgically challenging disease. The conventional thoracoabdominal aortic aneurysm repair technique using cardiopulmonary bypass is a high-risk procedure. However, a recently developed endovascular technique may be an alternative treatment for the disease, but faces the obstacle of lesional restriction. This new technique uses a hybrid strategy to overcome the limits of endovascular thoracoabdominal aortic aneurysm repair. Herein, we report on a successful outcome after performing the hybrid visceral debranching procedure.

Venous aneurysms are uncommon in the lower limb and are more frequently found in the neck and thoracic and visceral veins. However, they have been reported to cause thrombosis, pulmonary thromboembolism, and other related complications. Popliteal venous aneurysms are often undetected because they are usually asymptomatic, but they may cause pulmonary thromboembolic events. We experienced a case of a 44-year-old man who was referred for recurrent pulmonary thromboembolism. He showed no other symptoms or signs except shortness of breath. A popliteal venous aneurysm was diagnosed incidentally because the examinations were performed to detect a deep vein thrombosis in relationship to the patient's history of pulmonary thromboembolism. We report a case of surgical treatment for a popliteal venous aneurysm that was complicated by pulmonary thromboembolism.

The superficial femoral artery (SFA) is a relatively rare location for lower limb aneurysmatic disease. In the literature, this disease is described an association between a relatively high growth rate and/or the rupture of aneurysms and chemotherapeutic agents. We report a case of the rupture of a giant SFA aneurysm in a patient during chemotherapy for acute lymphatic leukemia.

Innominate artery aneurysms are challenging for surgeons to treat because of the requirement for brain protection during surgery. In innominate artery aneurysms, the endovascular approach does not require cardiopulmonary bypass, but patients who can be treated using this approach are limited in number, and the long-term results of endovascular treatment are unclear. Here, we report our experience of successfully treating a patient with an innominate artery aneurysm using near-infrared spectroscopy without cardiopulmonary bypass support or hypothermic circulatory arrest.

A 34-year-old man who had undergone aortic valve replacement 8 years ago underwent an additional Bentall operation due to mechanical valve dehiscence 2 years later. Subsequently, he was diagnosed with Behçet disease and Batter syndrome. A week after being hospitalized again due to chest pain and dyspnea, a large pseudo-aneurysm was detected on computed tomography. Because of the excessively large size of the pseudo-aneurysm, surgical treatment seemed very risky. Therefore, we planned to perform thoracic endovascular aortic repair (TEVAR) and treated him successfully. However, the patient experienced recurrence of the same symptoms 4 months later, and was found to have type IV endoleak. He received a TEVAR procedure again, and it was successful.

Objective : Recently, three-dimensional (3D) printed models of the intracranial vascular have served as useful tools in simulation and training for cerebral aneurysm clipping surgery. Precise and realistic 3D printed aneurysm models may improve patients' understanding of the 3D cerebral aneurysm structure. Therefore, we created patient-specific 3D printed aneurysm models as an educational and clinical tool for patients undergoing aneurysm clipping surgery. Herein, we describe how these 3D models can be created and the effects of applying them for patient education purpose. Methods : Twenty patients with unruptured intracranial aneurysm were randomly divided into two groups. We explained and received informed consent from patients in whom 3D printed models-(group I) or computed tomography angiography-(group II) was used to explain aneurysm clipping surgery. The 3D printed intracranial aneurysm models were created based on time-of-flight magnetic resonance angiography using a 3D printer with acrylonitrile-butadiene-styrene resin as the model material. After describing the model to the patients, they completed a questionnaire about their understanding and satisfaction with aneurysm clipping surgery. Results : The 3D printed models were successfully made, and they precisely replicated the actual intracranial aneurysm structure of the corresponding patients. The use of the 3D model was associated with a higher understanding and satisfaction of preoperative patient education and consultation. On a 5-point Likert scale, the average level of understanding was scored as 4.7 (range, 3.0-5.0) in group I. In group II, the average response was 2.5 (range, 2.0-3.0). Conclusion : The 3D printed models were accurate and useful for understanding the intracranial aneurysm structure. In this study, 3D printed intracranial aneurysm models were proven to be helpful in preoperative patient consultation.

거대 우관상 동맥류를 동반한 우관상 동맥에서 좌심실로 유출되는 관상 동맥루는 매우 드문 질환이며 동맥류 파열과 심부전, 심내막염으로의 진행 가능성이 있으므로 수술적 치료가 요구되는 질환이다. 본 증례는 47세 남자 환자가 3개월 전부터 시작된 운동 시 호흡 곤란을 주소로 내원한 환자로 흉부 전산화 단층 촬영과 관상동맥 조영술을 통해 거대 우관상동맥류 및 관상동맥-좌심실루로 진단되어 거대 관상동맥류 절제술 및 관상동맥 우회술을 시행하여 성공적으로 치험하였기에 보고하는 바이다.

대동맥궁에 발생한 동맥류에 대한 수술적 치료는 침습적인 수술이며 수술 후 높은 유병률과 사망률이 보고되고 있는 실정이다. 그러나 최근 많은 경우에서 이에 대한 치료로 스텐트-그라프트와 더불어 좌측 쇄골하동맥 등에 우회술을 동시에 시행하는 hybrid 방법이 사용되고 있으며 좋은 결과들이 보고되고 있다. 이에 저자들은 대동맥궁의 동맥류 환자에 대해서 스텐트-그라프트 삽입과 좌측 쇄골하동맥 우회술을 동시에 시행하였기에 저자들의 치험예를 문헌고찰과 함께 보고하는 바이다.

승모판하 좌심실류는 흑인들에서 주로 발생하는 드문 질환이다. 저자들은 심실성 빈맥을 동반한 승모판하 좌심실류의 수술 치험을 보고하고자 한다. 환자는 68세 남자로 수술은 통상적인 저체온 심폐 바이패스 하에서 진행하였다. 심첨부를 들어올리고 좌심실 후방 기저부에 위치한 심실류에 직접 종절개를 넣고 먼저 심실류의 목에 해당하는 부위의 심내막을 돌아가며 고주파절제술(radiofrequency ablation)을 시행한 다음 승모판 및 판막하 구조물을 피해 첨포를 이용한 심실내 심실류봉합술(endoaneurysmorrhaphy)을 시행하였다. 수술 후 경과는 양호하였으며 현재 술 후 2년 정도 경과한 상태로 부정맥의 재발이나 승모판 기능이상은 관찰되지 않고 있다.

Unruptured non-traumatic dissecting aneurysm in the M4 segment of the middle cerebral artery (MCA) accompanied by complete occlusion of the ipsilateral internal cerebral artery (ICA) has never been reported. A 41-year-old man presented with an infarction manifesting as left-sided weakness and dysarthria. Magnetic resonance angiography revealed a subacute stage infarction in the right MCA territory and complete occlusion of the right ICA. Angiography demonstrated aneurysmal dilatation of the M4 segment of the right MCA. Surgery was performed to prevent hemorrhage from the aneurysm. The aneurysm was proximally clipped guided by Navigation-CT angiography and flow to the distal MCA was restored by superficial temporal artery-middle cerebral artery (STA-MCA) anastornosis. We report this rare case with literature review.
