- W2005364254 abstract "Visualization of portosystemic venous collaterals with arterial portography is often unsatisfactory even when vasodilator drugs are used. In this investigation arterial portography performed during reactive hyperemia following a temporary SMA occlusion is compared to currently used clinical methods in cirrhotic dogs with stable portal hypertension induced by fractionated polyvinyl alcohol embolization of the portal vein. Following a 2-minute balloon occlusion of the SMA a maximum increase in portal blood flow of 240% over the pre-occlusion value was found while the maximum increase in portal flow after 1 mg/kg tolazoline injected into the SMA amounted to only 110%. Compared to arterial portography performed with 32 ml diatrizoate 76% injected at a rate of 8 ml/sec into the SMA with and without a preceding 5 mg/kg tolazoline SMA injection, a significant earlier and better opacification of the portal system and portosystemic venous collaterals was found after a 2-minute SMA balloon occlusion. Simultaneous portal vein blood sampling revealed a 50–100% higher peak blood iodine concentration after SMA occlusion when compared to the other 2 investigated techniques. Encountered complications were all related to the used balloon catheter that is commercially available for human use and included interluminal leak, balloon rupture and detachment, failure to deflate the balloon and perforation. It is concluded that a significant improvement in arterial portography over currently used clinical methods can be achieved when performed immediately after a temporary occlusion of the SMA, provided a safe diagnostic balloon catheter is (becomes) available.
