This retrospective case-control study from a Level I trauma center examines which pelvic fracture patients are at risk for recurrent arterial hemorrhage after initial angiographic embolization. It identifies independent predictors of rebleeding and characterizes the source of recurrent hemorrhage on repeat angiography. The study spans 556 patients who underwent pelvic angiography over five years, with 42 requiring a second angiogram.
A patient with an unstable pelvic fracture gets to angiography, bleeds are embolized, and the team breathes a sigh of relief. This paper is a reminder that 7.5% of those patients will rebleed — and three-quarters of them will bleed from an entirely new vessel, not the one you just treated.
The two numbers to know: embolizing more than two arteries at the initial angiogram carries an OR of 16 for recurrence; transfusion faster than 2 units/hour carries an OR of 6.9. When you see these features, the arterial sheath should stay in for 48–72 hours and a low threshold for repeat angiography should be maintained.
Pubic symphysis diastasis is an additional flag. It appeared in 35% of recurrent bleeders vs. 13% of those who did not rebleed. On the plain film in the trauma bay, a widened symphysis should raise your index of suspicion for ongoing arterial injury even after apparent embolization success.
The editorial commentators frame this within the concept of "damage-control angiography". The idea that a rapid bilateral internal iliac embolization with Gelfoam slurry may be preferable to time-consuming selective coiling in the most unstable patients, reserving definitive vessel-by-vessel treatment for a second look when physiology is restored.
