  • Variant Anatomy of the External Jugular Vein
    ORIGINAL COMMUNICATION Anatomy Journal of Africa. 2015. 4(1): 518 – 527 VARIANT ANATOMY OF THE EXTERNAL JUGULAR VEIN Beda O. Olabu, Poonamjeet K. Loyal, Bethleen W. Matiko, Joseph M. Nderitu , Musa K. Misiani, Julius A. Ogeng’o Corresponding Author: Beda Otieno Olabu P.O.Box 30197 – 00100 GPO, Nairobi Kenya Email: [email protected] or [email protected]. Cell phone: +254 720 915 805 or +254 736 791 617 ABSTRACT Variant anatomy of the external jugular vein is important when performing invasive procedures in the neck. Although there are a number of case reports on some of these variations, there are few descriptive cross-sectional regarding the same. This study therefore aimed at describing the variant anatomy of the external jugular vein as seen in a sample Kenyan population. One hundred and six (106) sides of the neck from 53 cadaveric specimens (70 males and 36 females) in the Department of Human Anatomy, University of Nairobi, Kenya, were used. Pattern and level of formation, course, communications and termination were studied by dissection. The vein was absent in 14.2% of cases, all males. It was formed within the substance of the parotid gland in 44%, and did not receive posterior auricular vein in 6.6%. Variant communications noted included facial vein, internal jugular, and a presence of a large anastomotic vein connecting it to the anterior jugular. It was duplicated in 2.2% cases and terminated into internal jugular vein in 7.7% of cases. The most common variations were in origin, course, communications and termination. These may limit its clinical utilization, and their awareness is important when considering the vein for any invasive procedure.

NICULESCU Department of Anatomy and Embryology “Victor Babeş” University of Medicine and Pharmacy, Timişoara Abstract The study conducted on 60 human cadavers preserved in formalin, in the Anatomy Laboratory of the “Victor Babes” University of Medicine and Pharmacy Timisoara, during 2000–2006, observed the internal and external jugular veins from the point of view of their origin, course and affluents. The morphological variability of the jugular veins (external jugular that receives as affluents the facial and lingual veins and drains into the internal jugular, draining the latter’s territory – 3.33%; internal jugular that receives the lingual, upper thyroid and facial veins, independent – 13.33%, via the linguofacial trunk – 50%, and via thyrolinguofacial trunk – 33.33%) made possible the correlation of these anomalies with disorders in the ontogenetic development of the veins of the neck. Knowing the variants of origin, course and drainage area of jugular veins is important not only for the anatomist but also for the surgeon operating at this level.

This study described changes in the following structures: retromandibular vein and its divisions, including the relationship with the facial nerve, facial vein, common facial vein and jugular veins. Material and Methods: The variations of the veins were analyzed in three heads, five hemi-heads (right side) and two hemi-heads (left side) of unknown age and sex. Results: The changes only on the right side of the face were: union between the superficial temporal and maxillary veins at a lower level; absence of the common facial vein and facial vein draining into the external jugular vein. While on the left, only, it was noted: posterior division of retromandibular, after unite with the common facial vein, led to the internal jugular vein; union between the posterior auricular and common facial veins to form the external jugular and union between posterior auricular and common facial veins to terminate into internal jugular.

  • 7. Internal Jugular Vein the Internal Jugular Vein Is a Large Vein That Receives Blood from the Brain, Face, and Neck
    د.احمد فاضل Lecture 16 Anatomy The Root of the Neck The root of the neck can be defined as the area of the neck immediately above the inlet into the thorax. Muscles of the Root of the Neck Scalenus Anterior Muscle Scalenus Medius Muscle The Thoracic Duct The thoracic duct begins in the abdomen at the upper end of the cisterna chyli. It enters the thorax through the aortic opening in the diaphragm and ascends upward, inclining gradually to the left. On reaching the superior mediastinum, it is found passing upward along the left margin of the esophagus. At the root of the neck, it continues to ascend along the left margin of the esophagus until it reaches the level of the transverse process of the seventh cervical vertebra. Here, it bends laterally behind the carotid sheath. On reaching the medial border of the scalenus anterior, it turns 1 downward and drains into the beginning of the left brachiocephalic vein. It may, however, end in the terminal part of the subclavian or internal jugular veins. Main Nerves of the Neck Cervical Plexus Brachial Plexus The brachial plexus is formed in the posterior triangle of the neck by the union of the anterior rami of the 5th, 6th, 7th, and 8th cervical and the first thoracic spinal nerves. This plexus is divided into roots, trunks, divisions, and cords. The roots of C5 and 6 unite to form the upper trunk, the root of C7 continues as the middle trunk, and the roots of C8 and T1 unite to form the lower trunk.

Cranial nerve injuries remain one of the major contributor to the postoperative morbidities. Anatomical dissections were carried out on 44 sides of 22 cadaveric heads following the classical CEA procedure to investigate the variations of the local anatomy as a contributing factor to cranial nerve injuries.
