The use of near-infrared spectroscopy in the diagnosis of peripheral artery disease: A systematic review.

Background: Peripheral arterial disease is a stenosis or occlusion of peripheral arteries that results in compromised blood flow and muscle ischemia. The available diagnostic methods are mostly used to measure and visualize blood flow and are not useful in the evaluation of perfusion, especially in diabetic patients, which is now considered to be a research priority by most of the vascular societies around the world as this is still a relatively poorly studied phenomenon.

Objective: The aim of this review is to explore the clinical significance of muscle tissue oxygenation monitoring in lower-extremity peripheral artery disease diagnosis using the near-infrared spectroscopy method.

A Bleeding Uretero-Arterial Fistula: Open Repair After Unsuccessful Endovascular Treatment.

Introduction: Uretero-arterial fistula (UAF) poses major challenges in management and diagnosis due to the rarity of this condition and associated high morbidity/mortality rates.

Methods: We describe a case of a UAF associated with previous aorto-biiliac grafting, ureteric stenting and right nephrectomy because of chronic pielonephritis and complicated by surgical site infection. This case illustrates a very complex pathology, with a challenging diagnosis and multiple treatment options.
