In prospective, non-randomized study of patients with cirrhosis, we found under-dilation of PTFE-SGs during TIPS placement to be feasible, associated with lower rates of PSE, and effective.

Stent graft seems to improve primary patency for central venous stenosis and requires fewer reinterventions in a dialysis population with a high prevalence of long-term catheters.

Hong's technique was confirmed to be a simple, safe and highly effective way to remove incarcerated long-term central venous catheters. The refinements we adopted made the procedure more flexible and possibly less prone to complications. By properly using ordinary tools available anywhere, Hong's technique could be considered Columbus' egg in this previously risky field.
