Abstract

This study investigated the feasibility of performing an intrahepatic portacaval shunt (IHPCS) by means of transluminal laser angioplasty. In 10 anesthetized dogs, a catheter was introduced into a mesenteric vein and threaded into the portal vein (PV). Under fluoroscopy, a Ross needle was passed through the PV catheter, liver, and into the intrahepatic IVC. Following guide-wire exchange, a neodymium YAG laser hot-tip probe (power setting 8 W) was passed over the guide-wire to accomplish a transluminal IHPCS. In five animals, an IHPCS could not be accomplished. Initial and subsequent patency was confirmed by fluoroscopy. These early data suggest that transvenous laser-induced intrahepatic portacaval shunts may be feasible as a means of decompressing portal hypertension. Further research is necessary to investigate the long-term patency as well as this technique's ability to decompress the portal system.
