1.   The morbidity and mortality associated with percutaneous biopsy is very low, and with the use of a fine needle for aspiration cytology is negligible.

2.   Plugged liver biopsies are both effective and safe when used to perform percutaneous liver biopsies in patients with impaired coagulation.

3.   Investigation including imaging and a standard percutaneous liver biopsy, which showed congestion, some necrosis, but no fibrosis, confirmed the clinical diagnosis of venous outflow obstruction.
