Multicentric Angiographic Assessment of the Branching Patterns and Anastomotic Network of the Genicular Arteries, with Implications for Genicular Artery Embolization.

ABSTRACT:

Purpose

To describe the anatomy of the genicular arteries and their anastomoses based on intraprocedural digital subtraction angiography (DSA).

Materials and methods

This retrospective, multi-center study reviewed patients who underwent genicular artery embolization (GAE) between January 2019 and December 2023. DSA images were analyzed to assess the anatomy of the genicular arteries and their anastomoses.

Results

A total of 393 GAEs in 358 patients with minimal to severe knee osteoarthrosis (OA; Kellgren/Lawrence Grade I-IV) were analysed. Anastomoses between genicular branches were observed in all patients. In the medial compartment, anastomoses were identified between the descending genicular artery (DGA) and superior medial genicular artery (SMGA) in 158 GAEs (40%)
