• Percutaneous forceps biopsy provides relatively high accuracy in diagnosis of malignant biliary obstructions. • The predictive factors of false-negative biopsy were biopsy site and origin of primary tumour. • The procedure-related complications were low.
Vascular catheters are associated with complications such as infection, thrombosis and stenosis. The embolization of a venous catheter fragment is a rare complication. A 39-year-old woman underwent placement of a totally implantable venous access device for chemotherapy to treat a recurrent liposarcoma of the left thigh. The "pinch-off sign" was noted on a routine chest X-ray but that was ignored. Three-months after implantation of the intravenous access device, the indwelling central catheter was fractured and embolized to the pulmonary trunk. The catheter in the pulmonary trunk was successfully removed through a percutaneous femoral vein approach using a pigtail catheter and goose neck snare.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
