Failure of thumbtacks used in control of presacral hemorrhage.

We report a case of failure of thumbtacks used in achieving last-resort hemostasis in a gunshot injury to the presacral venous plexus/sacrum. Four of five thumbtacks used detached. The exact mechanism of failure is not known. To our knowledge, there are no reports of failure of these hemostatic devices in the literature. This finding suggests to us that thumbtack hemostasis is not without complication. It is not known whether injury to internal viscera and organs occurred secondary to the loose thumbtacks. We suggest that surgeons as well as pathologists use caution when exploring pelvic or abdominal cavities following pelvic vascular trauma due to the considerable danger posed by these sharp objects.
