Prevalence of anomalies and variants of coronary arteries: A single center study by coronary CT angiography.

Purpose: It has been demonstrated that the coronary artery anomalies (CAAs) are generally asymptomatic. However, some cases can cause severe life threatening events. As coronary computed tomography angiography (CCTA) has emerged as a non-invasive alternative to invasive coronary angiography for the evaluation of coronary anatomy, the prevalence of CAAs in CCTA may more closely reflect the true prevalence in the general population.

Topographic methods to expose the exiting points of supratrochlear, supraorbital, and zygomaticotemporal nerves.

Background/aim: We evaluated the relations of the exiting points of supratrochlear (STN), supraorbital (SON), and zygomaticotemporal (ZTN) nerves with certain landmarks to provide improved anatomic knowledge. Materials and methods: The twenty-eight hemifaces of 5 fresh frozen and 11 embalmed heads (5 female and 11 male cadavers) were dissected. Distance and angular measurements were made between the exiting points of the nerves to the midline, lateral, and medial canthi.

Bilateral persistent sciatic vein: report of a case with developmental, histological and clinical aspects.

Objective: Bilateral large variant veins were encountered in the lower extremity. It was aimed to identify the structural characteristics of this rare case and then, regarding the structural features, to overview its formation process and denomination.

Material And Method: During the routine dissection of a 93-year-old male cadaver, bilateral large variant veins were found at the thigh.
