RESUMO
A fibrin glue kit consists of separate solutions of fibrinogen and thrombin that instantly coagulate when mixed together and can be used as an embolic agent and tissue adhesive in several interventional procedures, such as the closure of enterocutaneous, postoperative pancreatic, and bronchopulmonary fistulas, embosclerosis of biloma, and portal vein embolization. Separate and simultaneous injections of fibrinogen and thrombin solutions at the target site are necessary; therefore, insertion of two catheters or a balloon catheter with multiple lumen is required. The combined use of metallic coils is also effective for a large fistula as the coils can provide a matrix for retaining the fibrin glue, in addition to partially occluding the fistulous tract. Mixing contrast medium or iodized oil with a thrombin solution is also key to achieving radiopacity.
