  • Title: The incidence of shunt occlusion following portosystemic decompression.
    Author: Mehigan DG, Zuidema GD, Cameron JL.
    Journal: Surg Gynecol Obstet; 1980 May; 150(5):661-3. PubMed ID: 7368049.
    Abstract:
    The English literature on portosystemic decompression procedures was reviewed for an 11 year period and is available upon request to the authors. Information on 1,586 end-to-side portacaval shunts, 308 side-to-side portacaval shunts, 550 standard splenorenal shunts, 436 interposition shunts, 319 distal splenorenal shunts and 136 direct mesocaval shunts was obtained. Operative mortality ranged from a low of 6 per cent in patients undergoing a direct mesocaval shunt to a high of 29 per cent among patients undergoing a side-to-side portacaval shunt. The incidence of portosystemic encephalopathy ranged from a low of 2 per cent for direct mesocaval shunts to a high of 36 per cent for side-to-side portacaval shunts. The occlusion rate was 18 per cent for the standard splenorenal shunt, 10 per cent for the distal splenorenal and interposition shunts, 7 per cent for the direct mesocaval and the end-to-side portacaval shunts and 2 per cent for the side-to-side portacaval shunt.
