Hepatic artery stenosis following adult liver transplantation: evaluation of different endovascular treatment approaches.

Purpose: To evaluate the efficacy and safety of hepatic artery interventions (HAI) versus extra-hepatic arterial interventions (EHAI) when managing clinically significant hepatic artery stenosis (HAS) after adult orthotopic liver transplantation.

Materials And Methods: A single-center retrospective cohort analysis was conducted on liver transplant patients who underwent intervention for clinically significant HAS from September 2012 to September 2021. The HAI treatment arm included hepatic artery angioplasty and/or stent placement while the EHAI treatment arm comprised of non-hepatic visceral artery embolization.

Renal vascular lesions: diagnosis and endovascular management.

Renal vascular abnormalities included in this review are renal artery aneurysms (RAA) and renal arteriovenous malformations (AVM). The clinical presentation, diagnosis, and principles of management with emphasis on endovascular techniques are discussed.

Visceral arteriography in trauma.

The nonoperative management including endovascular treatment of traumatic injuries to most abdominal solid viscera is increasingly gaining acceptance as treatment of choice in a select group of patients. The indications, techniques, and principles of endovascular management of hepatic, splenic, and renal injuries are discussed in this review.
