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%), the DGA and inferior medial genicular artery (IMGA) in 132 GAEs (34%), and the SMGA and IMGA in 64 GAEs (16%). In the lateral compartment, anastomoses were observed between the superior lateral genicular artery (SLGA) and inferior lateral genicular artery (ILGA) in 192 GAEs (49%), the ILGA and anterior tibial recurrent artery (ARTA) in 152 GAEs (39%), and between the SLGA, ILGA and ARTA in 91 GAEs (23%). Anastomoses between the medial and lateral compartments were identified between the DGA and SLGA in 59 GAEs (15%), the DGA and ILGA in 87 GAEs (22%), and the IMGA and ILGA in 94 GAEs (24%). The mean vessel diameter of the anastomoses ranged from 0.2 to 1.1 mm.
Conclusion: Anastomoses between genicular arteries are frequent and extensive, with diameters exceeding the sizes of particles (100-300 μm) and microcatheters (1.7-2.4F) commonly used in GAE.

CardioVascular and Interventional Radiology (CVIR) is the official journal of the Cardiovascular and Interventional Radiological Society of Europe, and is also the official organ of a number of additional distinguished national and international interventional radiological societies. CVIR publishes double blinded peer-reviewed original research work including clinical and laboratory investigations, technical notes, case reports, works in progress, and letters to the editor, as well as review articles, pictorial essays, editorials, and special invited submissions in the field of vascular and interventional radiology. Beside the communication of the latest research results in this field, it is also the aim of CVIR to support continuous medical education. Articles that are accepted for publication are done so with the understanding that they, or their substantive contents, have not been and will not be submitted to any other publication.
