[Percutaneous hepatic biopsy puncture in patients with hemostasis disorders. A new technique].

In order to avoid the inconveniences of the trans-jugular liver biopsy, a modified percutaneous liver biopsy with embolization has been performed in 27 patients with chronic hepatic diseases with or without hemostatic disorders. By means of a sheath and a Menghini or Tru Cut needle type, an embolization of the needle tract was carried out utilising coagulations factors (I, IIa and XIII). All procedures were laparoscopically visualised and the "Hepatic bleeding time" measured. With or without embolization, the "Hepatic bleeding time" found was 0-6 seconds and 2-6 minutes, respectively. This modified technic is a safe and effective method for high risk bleeding patients and no hemorrhagic complications postprocedure observed.
