Newly designed occluder pin for presacral hemorrhage.

Conventional hemostatic measures are often unsatisfactory in presacral venous bleeding occurring during surgical mobilization of the rectum. We designed a new type of hemorrhage occluder pin, with a ridged shaft, which may be rapidly placed into the sacrum to control hemorrhage. The aims of this study were 1) to assess the best pin shaft length by measuring the thickness of human sacral vertebral bodies, 2) to measure the forces needed to pull the newly designed pin out of the human sacrum compared with conventionally shaped titanium thumbtacks, and 3) to assess clinically the efficacy of the new device. Four fresh cadaveric pelves were isolated and cut on a sagittal plane, and the thickness of each vertebral body was measured. Titanium pins, both with ridged and with smooth shafts, were used. Twelve-millimeter-shaft pins were used for S1 and S2, and 7-mm pins were used for S3, S4, and S5. Pins were inserted into each sacral vertebra, and the forces needed to extract them from the bone were measured by computerized dynamometry. Significantly more force was required to extract ridged vs. smooth pins, both with 12-mm and with 7-mm shafts. There was no significant difference between the forces needed to pull out 12-mm vs. 7-mm pins. The new pin was successfully used to stop presacral hemorrhage in three patients with no complications one, three, and six months after surgery. This newly designed hemorrhage occluder pin may represent an improved method of controlling presacral venous hemorrhage.[1]
