This case describes the use of the Surfacer® Inside-Out Access Catheter System (SIO) from Merit Medical in an occluded inferior vena cava. The procedure typically utilizes right femoral vein access with contraindications of acute iliocaval thrombosis due to possible embolization. After history and imaging studies, the occlusion was determined to be chronic in this case, and a decision was made to employ the SIO procedure using an indwelling catheter. This case demonstrates the use of the SIO procedure in certain settings in patients with central venous occlusions who have exhausted all other options.
本病例描述了美力医疗公司的Surfacer® 由外向内入路导管系统(SIO)在闭塞性下腔静脉中的应用。该手术通常采用右股静脉入路,因可能发生栓塞而存在急性髂股静脉血栓形成的禁忌症。经过病史询问和影像学检查,确定该病例中的闭塞为慢性,因此决定使用留置导管进行SIO手术。本病例展示了SIO手术在中央静脉闭塞且已用尽所有其他治疗方案的特定患者中的应用。
