Diagnostic Validation Study. Relationship Between Optical Spectroscopy and Ankle Brachial Index Tests for Peripheral Artery Disease.

Introduction: Ankle brachial index (ABI) is an essential diagnostic test for peripheral artery disease. It has some important limitations so it can´t always be performed. In those cases, tissue oximetry based on near-infrared spectrum could overcome these limitations.

Submandibular approach and use of Ligasure(®) system in a complex carotid paraganglioma.

Unlabelled: Carotid paragangliomas are rare tumors of slow growth, progressive, and highly vascularized; surgery is the chosen treatment, and most surgeons perform an approach with a longitudinal cervicotomy.

Objective: We present a case of carotid paraganglioma Shamblin III with skull base extension.

Methods: Submandibular approach and vascular sealing device of the Ligasure(®) system were used in the surgery.
