Uterine artery embolization in Tanzania: a procedure with major public health implications CVIR Endovasc. Pub Date : 2023-08-07 Balowa Musa, Jared Mark Alswang, Rose Di Ioia, Lydia Grubic, Azza Naif, Erick Michael Mbuguje, Victoria Vuong, Janice Newsome, Behnam Shaygi, Vijay Ramalingam, Fabian Max Laage Gaupp
The burden of uterine fibroids is substantial in sub-Saharan Africa (SSA), with up to 80% of black women harboring them in their lifetime. While uterine artery embolization (UAE) has emerged as an effective alternative to surgery to manage this condition, the procedure is not available to the vast majority of women living in SSA due to limited access to interventional radiology (IR) in the region.

Complications in Interventional Radiology: the role of clinical governance and iterative hospital systems in quality improvement CVIR Endovasc. Pub Date : 2023-08-05 Warren Clements, Jim Koukounaras
As modern Interventional Radiology (IR) evolves, and expands in scope and complexity, it will push the boundaries of existing literature. However, with all intervention comes risk and it is the shared judgement of the risk–benefit analysis which underpins the ethical and legal principles of care in IR. Complications in medicine are common, said to occur in 9.2% of in-hospital healthcare interactions

The ViaHole technique: a novel approach for recanalizing major side branch occluded by Viabahn stent-graft CVIR Endovasc. Pub Date : 2023-07-15 Takuya Haraguchi, Masanaga Tsujimoto, Ryo Otake, Yoshifumi Kashima, Katsuhiko Sato, Tsutomu Fujita
In managing arterial rupture, stent-graft implantation may cause limb ischemia by crossing a major branch for hemostasis. The ViaHole technique could circumvent a major branch occlusion. The process involved advancing retrograde devices into an occluded major branch by the stent-graft implantation to reach the outer surface of the stent-graft, puncturing the stent-graft with a 20-gauge needle to touch

Complex endoleak treatment after failed endovascular aortic repair CVIR Endovasc. Pub Date : 2023-07-05 Jan Raupach, Jan Masek, Sindharta Venugopal, Ondrej Renc, Michal Lesko, Maly Radovan
Endovascular aneurysm repair (EVAR) has created new possibilities for patients with abdominal aortic aneurysms (AAAs), and in recent years it has become tremendously popular. Use of EVAR in selected groups of patients allows mortality and morbidity to be reduced in comparison to open repair. However, complications such as endoleaks (ELs) can be of great concern and warrant urgent therapy to prevent

A case of chronic total occlusion in popliteal artery recanalized by double snare piercing technique CVIR Endovasc. Pub Date : 2023-06-22 Hirokazu Miyashita, Kazuki Tobita, Syuhei Uchida, Eiji Koyama, Yusuke Tamaki, Takayoshi Yamashita, Shigeru Saito
Although majority of cases with chronic total occlusion (CTO) in femoro-popliteal lesion were treated with antegrade approach only, some lesions require alternative approach due to its complexity. Bi-directional approach is useful on endovascular therapy (EVT) for CTO; however guidewire passage through the lesion is impossible in some challenging cases. The present case shows a successful re-entry
