Transfemoral Transcaval Liver Biopsy: A Single Center Experience in 657 Cases.

This study reviews 657 transvenous liver biopsies using a transfemoral transcaval (TFTC) approach performed at a single institution between February 2014 and February 2024, highlighting three severe adverse events (AE). The retrospective review was performed for all TFTC liver biopsies. Technical success was attained in 99.

The Intracranial and Intracanalicular Optic Nerve as Seen Through Different Surgical Windows: Endoscopic Versus Transcranial.

Background: Surgically manageable lesions involving the intracranial or intracanalicular portions of the optic nerve (cranial nerve II) can be approached through several different operative windows. Given the complex anatomy of the optic nerve and its surrounding neurovascular structures, it is essential to understand the conventional and topographic anatomy of the optic nerve from different surgical perspectives as well as its relationship with surrounding structures. We describe the intracranial and intracanalicular course of the optic nerve and present an analytical evaluation of the degree of exposure provided by several different transcranial and endoscopic surgical approaches.
