[Case-control study on transcatheter artery embolization for massive bleeding due to pelvic fractures]

To investigate the techniques and curative effects of transcatheter artery embolization (TAE) for massive bleeding due to pelvic fractures.

The clinical data of 92 patients with haemorrhage due to pelvic fractures from March 1998 to February 2008 were retrospectively analyzed. Among 53 patients treated conservatively such as massive transfusion and fluid infusion in the control group, 43 patients were male and 10 patients were female, ranging in age from 27 to 61 years, averaged (37.2 +/- 5.7) years. Among 39 patients who were hemodynamically unstable or had evidences of ongoing hemorrhage required TAE, 26 patients were male and 13 patients were female, ranging in age from 26 to 62 years, with a mean age of (35.3 +/- 9.5) years. The clinical date such as blood or fluid transfusion volume, shock redress time and survival rate were compared between the two groups. The hemostatic efficiency and complications of the surgery were also analyzed.

The average hemostasis time of TAE group was 2 hours. There were no intraoperative injuries of blood vessels, nerve or vital organs. Three patients had lower limbs numbness and 5 patients had gluteal skin redness after the operation. The blood transfusion or fluid infusion volume, shock redress time and survival rate were all significantly better than those in the conservative group.

TAE is an early,rapid and effective method in controlling haemorrhage due to pelvic fractures.
