The feasibility of control of traumatic hepatic hemorrhage by angiographic transcatheter embolization was investigated. Bleeding sites were created in the livers of each of twelve dogs, and the hepatic artery was occluded with Gelfoam. Successful control of bleeding was demonstrated by postembolization angiography in all twelve animals. Initial elevations in alkaline phosphatase and serum glutamic pyruvic transaminase values returned to their baseline in four weeks. Recanalization of the hepatic artery in the five surviving animals was shown by follow-up angiograms. Transcatheter embolic control of traumatic hepatic hemorrhage may be a useful adjunct to surgical therapy.

The hepatic artery was embolized with Gelfoam in 12 dogs to evaluate the effect of embolization on hepatic function. Liver function studies, including SGPT, alkaline phosphatase, BSP test, and bilirubin, were done serially over a 6 week period following the embolization. Eleven of the 12 embolized dogs survived the 6 week experimental period. Hepatic artery embolization caused some liver damage; however, recovery occurred by 6 weeks. These results suggest a possible therapeutic role for hepatic artery embolization in patients with massive hepatic bleeding or hemobilia who are not surgical candidates and who would require hepatic lobectomy or dearterialization to control the bleeding.

Segmental and complete hepatic artery embolization with Ivalon (polyvinyl alcohol) particles (0.25 to 1 mm) was performed in 12 dogs to evaluate hepatic function alterations and histopathological changes. In dogs undergoing segmental embolization, liver function alterations were minimal and the liver was normal, both grossly and microscopically, at autopsy. In dogs undergoing complete hepatic embolization, only two had significant elevation of SGOT and alkaline phosphatase levels, which normalized in 2 and 4 weeks; one of these two dogs also had an elevated bilirubin level. A focal hepatic infarct was observed both grossly and microscopically in one dog and only microscopically in four dogs. Two dogs died of pancreatic abscess due to unintentional pancreatic embolization. The study suggested that segmental embolization with Ivalon particles was well tolerated by dogs, and complete hepatic embolization resulted in hepatic function changes and focal infarction comparable with Gelfoam embolization.

Gelatine sponge because of its flexibility, biocompatibility, and biodegradability, has the potential to be used as a scaffold to support osteoblasts and to promote bone regeneration in defective areas. This study aimed to determine osteoblast proliferation, differentiation, and integration in modified and un-modified gelatine sponges. Three scaffolds were studied: gelatine sponge (Gelfoam), gelatin sponge/mineral (hydroxyapatite) composite, and gelatin sponge/polymer (poly-lactide-co-glycolide) composite. 2-D plastic coverslip was used as control. The gelatin sponges were modified using PLGA coating and mineral deposition to increase biodegradation resistance and osteoblast proliferation respectively. The scaffolds were characterized using Scanning Electron Microscopy (SEM) and X-ray diffraction. Cell number (DNA content), cell-replication rate (thymidine assay), and cell differentiation (alkaline phosphatase activity) were measured 24 h, 3 days, and 1, 2, 3 weeks after the osteoblast-like cells were cultured onto the scaffolds. Cell penetration into the sponges was determined using haematoxylin-eosin staining. Both modified and unmodified gelatine sponges demonstrated ability to support cell growth and cells were able to penetrate into the sponge pores. In a comparison of different scaffolds, cell number and cell replication were highest in sponge/hydroxyapatite composite and lowest in sponge/PLGA composite.
