Intravascular Ultrasound Imaging Versus Digital Subtraction Angiography in Patients with Peripheral Vascular Disease.

Objectives: The evaluation of arterial plaque morphology and vessel diameter is a vital component of peripheral vascular interventions. Historically, digital subtraction angiography (DSA) has been considered the gold standard for vessel sizing and treatment. However, this modality has the limitation of providing a two-dimensional image of a three-dimensional luminal structure.

Lack of Association Between Limb Hemodynamics and Response to Infrapopliteal Endovascular Therapy in Patients With Critical Limb Ischemia.

Background: Non-invasive limb hemodynamics may aid in diagnosis of critical limb ischemia (CLI), although the relationship with disease severity and response to endovascular therapy is unclear.

Methods And Results: This prospective, single-center study enrolled 100 CLI patients (Rutherford class 4-6) who underwent infrapopliteal endovascular revascularization (175 lesions) in the Peripheral RegIstry of Endovascular Clinical OutcoMEs (PRIME) registry. Hemodynamic measures included ankle-brachial index (ABI), toe-brachial index (TBI), and toe pressure (TP).

Ultrasound-Guided Arterial Access: Outcomes Among Patients With Peripheral Artery Disease and Critical Limb Ischemia Undergoing Peripheral Interventions.

Objective: Arterial cannulation is a vital component of endovascular interventions and often unconventional access approaches are required due to disease complexity. Historically, varying maneuvers have been utilized to obtain arterial access. Lack of consensus exists regarding the safest and most effective method.

Percutaneous Transluminal Angioplasty in Patients With Infrapopliteal Arterial Disease: Systematic Review and Meta-Analysis.

Background: Contemporary outcomes of percutaneous transluminal angioplasty for the treatment of infrapopliteal atherosclerotic lesions are not well characterized. Hence, a systematic review and meta-analysis was performed to determine the safety and effectiveness of this approach in patients with advanced below-the-knee arterial disease.

Methods And Results: MEDLINE and EMBASE databases were searched for contemporary studies (2005-2015) on the effects of percutaneous transluminal angioplasty for the treatment of infrapopliteal lesions.
