[Stab wound of the right branch of the portal vein. Suture. Healing].

The authors report a stab wound of the right branch of the portal vein observed at the Lariboisière hospital, and discuss 27 published cases of traumatic lesions of the portal vein or its branches. The treatment of choice of these lesions is mainly suture, which is the best procedure when there is a frank lesion without loss of tissue. Furthermore, we have found that ligature of one branch of the portal vein is possible, even if one does not carry out removal of the liver in the corresponding area. On the other hand, in no case, in a patient without liver disease or portal hypertension, should one carry out sudden total interruption of the portal blood flow.
