Comparison of Local Injection of Fresh Frozen Plasma to Traditional Methods of Hemostasis in Minimally Invasive Procedures.

Rationale and Objectives: To evaluate different techniques for reducing hemorrhagic complications in coagulopathic patients with elevated international normalized ratio having an image-guided percutaneous invasive procedure; techniques included systemic transfusion of fresh frozen plasma (FFP), local injection of FFP, percutaneous injection of gelatin sponge, and percutaneous placements of angiographic coils.
Materials and Methods: Retrospective review of 232 consecutive patients with known coagulopathy undergoing image-guided minimally invasive procedures were selected. Ninety-one patients had local FFP injected, 40 patients underwent local synthetic gelatin injection, 16 patients had percutaneous coil embolization, and 85 patients received systemic FFP. The number of bleeds, complications related to bleeds, and systemic complications were recorded. A 30 cc threshold was used to delineate significant bleeding.
Results: No patients experienced clinically significant or insignificant bleeding with local FFP injection (P value <.05). Other local hemostatic methods (Gelfoam, systemic FFP, and coil embolization) were associated with higher levels of bleeding (12.5%, 17.1%, 37.5%, respectively) and complications (7.5%, 31.4%, 37.5%, respectively). Systemic FFP infusion was associated with respiratory, infectious, and mortal complications.
Conclusions: Local injection of blood products provides a safe and efficacious hemostatic agent to reduce the incidence of postprocedural bleeding. The technique is associated with lower rates of bleeding and systemic complications when compared to other local and systemic techniques. Further randomized prospective studies with a larger patient cohort need to be performed to corroborate these initial findings.
