Predictive Ability of the Pedal Medial Arterial Calcification Score for Major Adverse Limb Events Among Patients with Chronic Limb-Threatening Ischemia.

Background: Pedal medial arterial calcification (pMAC) is a potential predictor of major adverse limb events (MALEs) among patients with critical limb-threatening ischemia (CLTI). This study aims to validate the prognostic value of the pMAC score in predicting major lower-limb amputation (MLLA) and need for redo revascularisation.

Methods: A single-center study involving 196 patients diagnosed with CLTI, reviewed between 2012 and 2022.

Outcomes Following Vascular and Endovascular Procedures Performed During the First COVID-19 Pandemic Wave.

Objective: The first COVID-19 pandemic wave was a period of reduced surgical activity and redistribution of resources to only those with late stage or critical presentations. This Vascular and Endovascular Research Network COVID-19 Vascular Service (COVER) study aimed to describe the six-month outcomes of patients who underwent open surgery and or endovascular interventions for major vascular conditions during this period.

Methods: In this international, multicentre, prospective, observational study, centres recruited consecutive patients undergoing vascular procedures over a 12-week period.

The incidence of surgical site infection following major lower limb amputation: A systematic review.

Surgical site infections (SSIs) following major lower limb amputation (MLLA) in vascular patients are a major source of morbidity. The objective of this systematic review was to determine the incidence of SSI following MLLA in vascular patients. This review was prospectively registered with the International Prospective Register of Systematic Reviews (CRD42023460645).
