Intraoperative angiography for emergency cerebrovascular surgery using an exclusively developed radiolucent Sugita...

Intraoperative angiography during emergency cerebrovascular surgery, clipping operation for acute aneurysmal subarachnoid hemorrhage, is reported. For acquisition of intraoperative angiography, an exclusively developed radiolucent version of a Sugita head frame, made of engineering plastics for angiography, and an ordinary fluoroscopic unit were installed. In a radiolucent head frame, all the parts of the ordinary metallic Sugita multipurpose head frame, fixation and its accessories were made of high-molecular polymer plastics in the same size. In emergency cerebrovascular surgery, the radiolucent Sugita frame enabled us to carry out meticulous dissection and precise retraction control as the ordinary metallic system and to perform the intraoperative angiography if needed.
