An experimental pleural drainage device in hypertensive pneumothorax.

Purpose: To develop a specific device for pleural drainage in hypertensive pneumothorax.

Methods: The prototype was modeled from the free version of a 3D modeling application, printed on a 3D printer using ABS® plastic material, and tested in a pleural drainage simulator.

Results: Pleural drainage in the simulator using the prototype was feasible and reproducible.

Transcatheter arterial chemoembolization of hepatocellular carcinoma in a patient with celiac trunk occlusion: a therapeutic challenge.

Transcatheter arterial chemoembolization is a technique for provoking ischemia and cytotoxic activity by selectively injecting microspheres containing chemotherapy drugs into vessels supplying a tumor. An 87-year-old female patient on palliative treatment for hepatocellular carcinoma and with indications for chemoembolization underwent preparatory angiography, which revealed celiac trunk occlusion. The treatment option chosen was selective catheterization of the hepatic artery proper to release the chemotherapy agent via an alternative route through the superior mesenteric artery with communication using the pancreaticoduodenal arcade.
