Bilateral kinking of extracranial part of internal carotid artery with coiling and tortuosity of external carotid artery

A rare anatomic anomaly known as the twisted carotid artery is characterized by vascular elongation that results in an altered path. It could be an unexpected finding or have symptoms that are clinically noteworthy. The internal carotid artery or, less frequently, the common carotid artery is the most typical site. Additionally, bilateral tortuous carotid arteries may develop, resulting in "kissing carotids," a condition in which the carotid arteries are opposed one another. : This case report describes the bilateral presence of numerous loops in the exterior and internal carotid arteries of an adult 65 years old male cadaver. : These loops may cause a reduction in blood flow to certain areas of the head and neck. It is essential for understanding these unusual loops for different surgical procedures. The aim of this paper is to enlighten physicians about the variations in these variants' etiology, anatomical characteristics, and associated clinical implications.
