Transfemoral access (TFA) is a widely used first-line approach for most peripheral vascular interventions. Since its introduction in cardiologic and neurointerventional procedures, several advantages of transradial access (TRA) over TFA have been demonstrated, such as patient preference, lower complication rates, early ambulation, and shorter hospital stay. However, studies reporting the safety and efficacy of this approach for peripheral vascular interventions performed by interventional radiologists are relatively few. This review aimed to summarize the technique and clinical applications of TRA in percutaneous transcatheter visceral artery embolization and the management of complications.

Systemic multiple aneurysms are rare, and an association between intracranial and visceral arterial or abdominal aortic aneurysm in the same patient is a very rare occurrence. We report herein three such cases. In one case, aneurysms of the right internal carotid artery(ICA) and the right middle cerebral arterial bifurcation(MCAB) coexisted with the inferior pancreaticoduodenal arterial pseudoaneurysm and two ileal arterial aneurysms. In another case, the patient had the A-com arterial aneurysm and the right renal arterial aneurysm. And in the other patient, he had the right vertebral artery dissecting aneurysm with the abdominal aortic aneurym. Initially, all patients were referred to our hospital with subarachnoid hemorrhage(SAH), and thereafter first two patients developed visceral arterial aneurysm rupture in the course of hospital stay and in the last patient, the abdominal aortic aneurysm was detected incidentally during carotid angiogram for Guglielmi detachable coil(GDC) embolization of vertebral dissecting aneurym. After thorough review of our cases together with pertinent literatures, we emphasize the possibility of underlying extracranial aneurysms in ruptured intracranial arterial aneurysm patient and it's uncommon but fatal complication.

초 저체온 및 순환정지하 개심수술시 Aprotinin을 사용하는 경우 혈관내 응고와 관련된 신기능장애 등의 합병증이 증가된다는 보고가 있다. 저자들은 1992년 11월부터 95년 8월까지 초저체온 및 순환정지하에서 대 동맥 수술을 한 44례 환자 중 고농도 Aprotinin을 사용한 20명의 환자를 대상으로 수술 후 주요장기에 미치 는 aprotinin의 영향을 조사하였다. 초저체온하 순환정지 시에는 좌측대퇴동맥을 통하려 저혈류로 순환시켜 흉부대동맥내로 공기유입이 되지 않도록 하였으며 순환정지시간이 길어질 것으로 예상되거나 대동맥궁을 치 환하는 경우에는 선택적뇌관류를 하였다. 순환정지시 활성응고시간은 639초에서 1531초로 1례를 제외한 모 든 환자에서 활성응고시간을 750초 이상 유지하였다. 대상환자 20례중 수술사망은 4례에서 발생하였다. 사망원인은 출혈 1례, 폐출혈 1례, 좌 관상동맥 박리에 따른 좌심실 기능부전이 1례, 근리고 다발성 뇌경색이 1례 있었다. 수술 후 뇌손상이 2례에서 발생하였으나 1례는 수술전 부터 자측 총경동맥 박리가 원인이었고 1례에서는 그 원인을 알 수 얼었다. 생존한 환자중 수 술 후 신 기능이나 간기능의 이상은 얼\ulcorner다. 결론적으로 초저체온 및 순환정지를 이용한 대동맥수술시 avotinin을 사용한 결과 ACT를 750초이상 충분 히 유지하고, low flow retrograde perfusion을 유지하는 경우 신기능의 장애를 포함한 혈관내 응고와 관련된 합 병증이 증가되지 않고, 안전하게 사용할 수 있는 것으로 나타났다.

Percutaneous endoscopic gastrostomy (PEG) is widely used to provide nutritional support for patients with dysphagia and/or disturbed consciousness preventing oral ingestion, and PEG tube placement is a relatively safe and convenient non-surgical procedure performed under local anesthesia. However, the prevention of PEG-insertion-related complications is important. A 64-year-old man with recurrent pneumonia underwent tracheostomy and nasogastric tube placement for nutritional support and opted for PEG tube insertion for long-term nutrition. However, during the insertion procedure, needle puncture had to be attempted twice before successful PEG tube placement was achieved, and a day after the procedure his hemoglobin had fallen and he developed hypotension. Abdominal computed tomography revealed injury to a pancreatic branch of the superior mesenteric artery (SMA) associated with bleeding, hemoperitoneum, and pancreatitis. Transarterial embolization was performed using a microcatheter to treat hemorrhage from the injured branch of the SMA, and the acute pancreatitis was treated using antibiotics and supportive care. The patient was discharged after an uneventful recovery. Clinicians should be mindful of possible pancreatic injury and bleeding after PEG tube insertion. Possible complications, such as visceral injuries or bleeding, should be considered in patients requiring multiple puncture attempts during a PEG procedure.
