Retroperitoneal Packing or Angioembolization for Hemorrhage Control of Pelvic Fractures
Study Details
Study Description
Brief Summary
This study is designed to answer whether minimal invasive vessel clotting (angioembolization) or open surgery (retroperitoneal packing) is more effective for pelvic fractures with massive bleeding. Patients admitted at daytime (7am-5pm) are treated with angioembolization while patients admitted at nighttime (5pm to 7am) are treated with open surgery.

Detailed Description
In patients with pelvic fracture uncontrollable bleeding is the major cause of death within the first 24h after injury. Early hemorrhage control is therefore vital for successful treatment. Nowadays, recommended techniques for hemorrhage control in pelvic fractures are retroperitoneal pelvic packing and angioembolization, dependent upon the available technical staff and resources and the condition of the patient.
Retroperitoneal pelvic packing, on the one hand, is a relatively simple method in controlling pelvic hemorrhage even with limited resources. Since 89% of pelvic fracture hemorrhage originates from venous bleeding, fracture stabilization and compressive hemostasis by packing is a reasonable approach. Angioembolization, on the other hand, has great high effectiveness with regard to bleeding control, but requires an angiography suite and technical staff. Since hemostasis of retroperitoneal venous bleeding often can be achieved by external pelvic fixation, angioembolization is required for the 11% arterial bleedings which are hard to control by packing. Even though many authors see both methods as complements, time is crucial in the multitrauma setting and the severely injured patient does not tolerate multiple interventions well. Until now good predictors for treatment choice are unavailable, and management of hemodynamically unstable pelvic fractures remains a matter of debate.
This study was designed to answer following questions:
-
Is retroperitoneal pelvic packing or angiography superior with regard to in-hospital mortality, complications, required secondary procedures, or post-intervention blood loss?
-
Which of these methods is the more rapid intervention in the acute setting?
Study Design
Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Active Comparator: ANGIO Patients with persistent hemodynamic instability (systolic blood pressure (SBP) <90 mmHg after the transfusion of 4 packed red blood cell (PRBC) units in the emergency department) were taken urgently to the angiography suite for pelvic angiography. These patients had to tolerate transfer to the suite. Patients receiving primarily angioembolization therapy were defined as the ANGIO group. |
Procedure: ANGIO
Using en endovascular approach, bleeding arteries are identified and clotted using embolizing agents, or coils.

| Active Comparator: PACKING Indication for pelvic packing was persistent SBP<90 mmHg during the initial resuscitation period with 3000 ml of intravenous (IV) crystalloids and transfusion of 4 PRBC units. These patients were treated primarly with retroperitoneal packing, while angioembolization OR staff was unavailable (5pm-7am), and were defined as the PACK group. |
Procedure: PACKING
By retroperitoneal access the space in front of the pelvic fracture is compressed with surgical towels, which stops effectively venous bleeding
