Establishment of an interdisciplinary vascular anomalies program in Tanzania, East Africa.

Purpose: The aim of this project is the sustainable implementation of a vascular anomalies (VA) program in Tanzania.

Materials And Methods: In 2021 the first interdisciplinary VA program was initiated at Muhimbili National Hospital (MNH), Dar Es Salaam, Tanzania in a stepwise approach. During the planning phase the clinical need for minimally-invasive therapies of VAs and the preexisting structures were assessed by the local Interventional Radiology (IR) team at MNH.

Multicentered analysis of percutaneous sclerotherapies in venous malformations of the face.

Objectives: To evaluate the safety and outcome of image-guided sclerotherapy for treating venous malformations (VMs) of the face.

Materials And Methods: A multicenter cohort of 68 patients with VMs primarily affecting the face was retrospectively investigated. In total, 142 image-guided sclerotherapies were performed using gelified ethanol and/or polidocanol.

Image-Guided Embolotherapy of Arteriovenous Malformations of the Face.

Purpose: To evaluate the safety and outcome of image-guided embolotherapy of extracranial arteriovenous malformations (AVMs) primarily affecting the face.

Materials And Methods: A multicenter cohort of 28 patients presenting with AVMs primarily affecting the face was retrospectively investigated. Fifty image-guided embolotherapies were performed, mostly using ethylene-vinyl alcohol copolymer-based embolic agents.
