  Venous port occlusion can be either partial, when infusion is usually possible but aspiration fails, or complete, when neither infusion nor aspiration can be performed. Persistent Withdrawal Occlusion (PWO) is a special entity, specifically a form of partial occlusion characterized by persistent or intermittent inability to perform aspiration. It is advisable to follow certain precautionary measures to maintain port patency. Venous occlusions can be divided into non-thrombotic and thrombotic occlusions; obliterations caused by the presence of a Fibroblastic Sleeve (FS) constitute a special group. Ignoring the PWO phenomenon entails a higher risk of drug administration outside the Cavoatrial Junction (CAJ), with potential extravasation in extreme cases. Medical staff must make sure that the drug administered into the port enters the blood stream near the CAJ, they should also ideally i.. View More»
