볼크만 구축 환자의 술 전 준비 단계에서 척골 및 요골 동맥에 대한 도플러 초음파 유도 알렌 검사를 시행하여 청각 도플러와 CT-혈관조영술에서는 확인되지 않았던 척골 동맥의 혈류 감소를 인지할 수 있었다. 저자들은 척골 및 요골 동맥에 대한 도플러 초음파 유도 알렌 검사의 유용성에 대한 인식을 높이고자, 그 증례를 문헌고찰과 함께 보고하고자 한다.

Objective : Although a transradial angiography is accepted as the gold standard for cardiovascular procedures, cerebral angiography has been performed via transfemoral approach in most institutions. The purpose of this study is to present our experience concerning the feasibility, efficacy, and safety of a transradial approach to cerebral angiography as an alternative to a transfemoral approach. Methods : Between February 2007 and October 2009, a total of 1,240 cerebral angiographies were performed via a transradial approach in a single center. The right radial approach was used as an initial access route. The procedure continued only after the ulnar artery was proven to provide satisfactory collateral perfusion according to two tests (a modified Allen's test and forearm angiography). Results : The procedural success rate was 94.8% with a mean duration of 28 minutes. All supra-aortic vessels were successfully catheterized with a success rate of 100%. The success rates of selective catheterization to the right vertebral artery, right internal carotid artery, left internal carotid artery, and left vertebral artery were 96.1%, 98.6%, 82.6% and 52.2%, respectively. The procedure was performed more than twice in 73 patients (5.9%), including up to 4 times in 2 patients. The radial artery occlusion was found in 4 patients (5.4%) on follow-up cerebral angiography, but no ischemic symptoms were observed in any of the cases. Conclusion : This study suggests that cerebral angiography using a transradial approach can be performed with minimal risk of morbidity. In particular, this procedure might be useful for follow-up angiographies and place less stress on patients.

경피요골동맥삽관후 수지괴사가 발생되어 손목을 절단한 1례를 보고하며, 동맥삽관후 수지괴사가 유발될 수 있는 요인으로는 사용된 카테터의 크기, 종류, 천자횟수, 삽관거치기간 및 카테터삽관후 유지방법외에도 환자의 혈액구성성분변화, 혈액응고장애, 심박출량감소상태, 성별 등을 들 수 있으며, 본원에서 발생된 예에서는 수술후 환자가 심히 움직여 끈으로 동맥삽관된 손목을 침대에 묶어 놓음으로써 카테터에 의한 혈관손상이 심했음이 가장 큰 원인일 것으로 추측되며 그 외에도 혈액성분변화 및 응고장애에 의해 심한 혈전형성이나 heparin용액의 간헐적 관류시 발생될 수 있는 혈전의 전색도 가능성이 있을 것으로 사료된다.
