May 2, 2010 at 5:21 PM A New Soluble Gelatin Sponge for Transcatheter Hepatic Arterial Embolization. Cardiovasc Intervent Radiol. 2010 Apr 30; Authors: Takasaka I, Kawai N, Sato M, Sahara S, Minamiguchi H, Nakai M, Ikoma A, Nakata K, Sonomura T To prepare a soluble gelatin sponge (GS) and to explore the GS particles (GSPs) that inhibit development of collateral pathways when transcatheter hepatic arterial embolization is performed. The approval of the Institutional Committee on Research Animal Care of our institution was obtained. By means of 50 and 100 kDa of regenerative medicine-gelatin (RM-G), RM-G sponges were prepared by freeze-d! rying and heating to temperatures of 110-150 degrees C for cross-linkage. The soluble times of RM-GSPs were measured in vitro. Eight swine for transcatheter hepatic arterial embolization were assigned into two groups: six received 135 degrees C/50RM-GSPs, 125 degrees C/100RM-GSPs, and 138 degrees C/50RM-GSPs, with soluble time of 48 h or more in vitro; two swine received Gelpart GSPs (G-GSPs) with insoluble time of 14 days as a control. Transarterial chemoembolization was performed on two branches of the hepatic artery per swine. RM-GSPs heated at temperatures of 110-138 degrees C were soluble. Mean soluble times of the RM-GSPs increased with higher temperature. Hepatic branches embolized with G-GSP remained occluded after 6 days, and development of collateral pathways was observed after 3 days. Hepatic branches embolized with 135 degrees C/50RM-GSP and 125 degrees C/100RM-GSP remained occluded for 4 h, and recanalization was observed after 1 day. Hepatic branches embolized! with 138 degrees C/50RM-GS remained occluded for 1 day, and r! ecanaliz ation was observed after 2 days with no development of collateral pathways. In RM-GSs with various soluble times that were prepared by modulating the heating temperature, 138 degrees C/50RM-GSP was the soluble GSP with the longest occlusion time without inducing development of collateral pathways.
