aortic dissection occurs when a tear develops in the wall of the aorta, which is rare in the young population. this fatal disorder is hard to diagnose, especially in young patients. we present the case of aortic dissection in a 15-year-old boy referred to the emergency department of yazd university of medical sciences in november 2015. the patient presented to our department with sudden acute c...

An alternative pedicle trajectory for use at the superior end of a construct to limit dissection of the mobile superior facet joint and reduce incision length and muscle dissection, thus minimizing approach-related trauma during pedicle fixation, is reported. The medio-latero-superior trajectory technique involves a starting point on the medial aspect of the pars and angulation of the pedicle s...

absracta rare variant of ansa cervicalis was discovered during dissection of the neck in amale cadaver. the superior root of the ansa cervicalis was formed by the c1 ventralramus. it accompanied with the vagus nerve in place of the hypoglossal nerve and descendedinto the carotid sheath with it. moreover the c1 ventral ramus formed fromthe sheath and joined the inferior root from c2 and c3 ventr...

Carotid artery is the most important artery that carries the major part of the blood supply to the head and neck. The branching of the common carotid artery usually occurs at the upper edge of the thyroid cartilage. The placement of carotid sinus has also increased its importance in this area. Considering the clinical importance of knowledge about carotid artery variations, this case is reporte...

Superior laryngeal artery (SLA) is one of the main branches of the superior thyroid artery that its main function is to supply blood to the larynx. This artery is accompanied by the internal branch of superior laryngeal nerve; this relation has anatomical and surgical significance. In this paper, a case of anomalous origin of the superior laryngeal artery is reported. Abnormal origin of SLA fro...

Acute Type I aortic dissections are fast progressing highly mortal vascular emergencies if management delays. In this particular paper we report a case with a Type I aortic dissection mistreated for first 2 hours as thrombotic AMI, and aortic dissection diagnosis confirmed and treated surgically immediately. 59 years old male patient admitted to emergency room with sudden onset chest pain. Pati...

During the past few years, researchers and practitioners have developed novel techniques, using ansa cervicalis to innervate muscles of the larynx paralyzed due to surgical procedures carried out in the chest and neck areas. During routine dissection of a middle-age male cadaver, an unusual course of the superior root of the ansa cervicalis was observed. In this case, the su...

Aortic dissection is a fatal medical condition that requires urgent diagnosis and appropriate intervention. Because acute aortic dissection often manifests as sudden onset excruciating chest pain, physicians can easily reach a proper diagnosis. However, some patients with aortic dissection present with varied clinical manifestations without exhibiting typical chest pain, leading to a delayed di...

O B J E C T I V E : We developed an instrument (a dissector tool with micro vibrating system) to make make brain tissue dissection easy and safe. Method: We used this instrument and conventional technique to dissect 18 fresh cadaver sheep brains (9 of them were dissected by the vibrating-dissection technique and the remaining 9 with a conventional dissector). Dissection and separation were grad...
