AbstractHypoplasia of the vertebral artery (VA) is rare, and incidentally encountered in radiological imaging techniques. During routine activities in the Laboratory of Human Anatomy from University of Santa Cruz do Sul, Brazil, it was observed a 70 years old male cadaver with hypoplasia of the right VA. Thus, the purpose of this study is to report this case of hypoplasia of the VA emphasizing some morphological, functional and clinical data about this rare vascular abnormality, in order to offer useful information to anatomists, radiologists, vascular and head and neck surgeons. Moreover, to our knowledge, this variation has not been cited in recent medical literature.

Several thoracic vasculature variations were observed in an 81-year-old male cadaver during routine dissection. These included 5 common trunks of posterior intercostal arteries, a descending branch of the right vertebral artery, and atypical neurovascular relationships within intercostal spaces. On the right side, two common trunks of posterior intercostal arteries were observed supplying the 4th-7th intercostal spaces and 9th-11th intercostal spaces, respectively. There was also a small accessary branch supplying the 9th intercostal space. The first three posterior intercostal spaces on the right were supplied by a descending branch of the vertebral artery. On the left side, three common trunks of posterior intercostal arteries were encountered, supplying intercostal spaces 3-5, 6-7, and 11 plus the subcostal space. An atypical neurovascular relationship was observed in the right 6th intercostal space, as well as the left 2nd, 3rd, and 6th intercostal spaces. This is the first case report that presents 5 common trunks of posterior intercostal arteries, as well as common trunks in conjunction with other arterial variation in the posterior thoracic wall. These variations carry a high level of clinical significance and may be helpful in guiding decision-making related to surgical procedures related to the posterior thoracic cavity and spine.

Abstract Introduction: Saphenous nerve is the longest and largest pure sensory nerve, supplying the medial side of the thigh, leg and foot. Materials and Methods: In the present case study, during routine cadaveric dissection of the antero-medial part of the thigh, an interesting anomalous pattern of saphenous nerve was seen in the right lower limb of a 62 years old embalmed male cadaver from the Department of Human Anatomy, Universiti Putra Malaysia (UPM). Results: This saphenous nerve can be recognised as an unusual anatomical variant in which it gives a motor branch to the sartorius muscle during traversing the adductor canal and it was accompanied by blood vessels at the same time. The nerve continues its usual course and pierces the fascia lata, between the tendon of sartorius and gracilis and becomes subcutaneous. Conclusion: Knowledge of the variant anatomy of the saphenous nerve is important to surgeon in avoiding nerve injuries during adductor canal nerve block, nerve entrapment surgery, reconstructive surgery, pain management services and knee surgery successfully.

AbstractThe Vertebral artery is the first branch of subclavian artery. It is an important source of blood supply to the brain. During dissection of an adult male cadaver, a unilateral variation in the course of Vertebral artery was found. The right Vertebral artery took origin from the subclavian artery and entered foramen transversarium of fourth cervical vertebra. An understanding of the variability of the Vertebral artery remains most important in angiography & surgical procedures where an incomplete knowledge of its anatomy can lead to complications.

Brachial plexus is the plexus of nerves, that supplies the upper limb.Variations in the branches of brachial plexus are common but variations in the roots and trunks are very rare. Here, we report one of the such rare variations in the formations of the lower trunk of the brachial plexus in the right upper limb of a male cadaver. In the present case the lower trunk was formed by the union of ventral rami of C7,C8 and T1 nerve roots. The middle trunk was absent. Upper trunk formation was normal.

AbstractThe coexistence of different muscular-neurovascular variations is of significant clinical importance. A male cadaver, 76 years old at death, was subjected to routine anatomical dissection; the procedure was performed for research and teaching purposes at the Department of Anatomical Dissection and Donation, Medical University of Lodz. The right forearm and hand were dissected using standard techniques according to a strictly specified protocol. The presence accessory head of the flexor pollicis longus may potentially compress the anterior interosseous nerve. The present case report describes a rare variant of the ulnar head of the pronator teres, characterized by two independent bands (i.e., two proximal attachments). The main band originates from the coronoid process and the second originates from the tendon of the biceps brachii. This type of attachment could potentially affect the compression of the ulnar artery running between the two bands. Additionally, the accessory head of the flexor pollicis longus was observed, which started on the medial epicondyle; its coexistence with a high division median nerve creates a potential pressure site on the anterior interesosseous nerve.

Percutaneous Microwave Ablation

A 33 years’ old male complained of excessive salivation with frequent swallowing and spitting, which resulted in communication disturbance, reduced quality of life, and social embarrassment for 19 years. He had been diagnosed as sialorrhea and submandibular gland hyperfunction by stomatologist, then had unilateral submandibular gland resection 13 years ago, but the symptom relief was not satisfactory. After that, he had been treated with glycopyrrolate for less than a year, which was withdrawn because of the short duration of symptomatic control after each tablet take-in and intolerable side effects. With the wish to receive a new treatment with long term effectiveness, low re-operation risk and normal preserved saliva secretion function, the patient was subject to MWA for the right submandibular gland. After systematic clinical evaluation, US-guided percutaneous MWA was successfully performed with an uneventful post-operative course. The volume of the right submandibular gland and ablated area were measured precisely by an ablation planning software system with automatic volume measurement function based on three-dimensional reconstruction of the pre-operative and post-operative enhanced magnetic resonance imaging (MRI) raw data. Finally, the ablated volume was calculated as 62.2% of the whole right submandibular gland. The patient was discharged 1 day after the operation, with symptoms relieved significantly, the mean value of whole saliva flow rate (SFR) decreased from 11 ml to 7.5 ml per 15 minutes. During the follow up by phone three months after operation, the patient reported that the treatment effect was satisfactory, whereas the SFR value became stable as 7 ml per 15 minutes, drooling frequency and drooling severity (DFDS) score decreased from 6 to 5, drooling impact scale (DIS) score decreased from 43 to 26. US-guided percutaneous MWA of submandibular gland seems to be an alternative, minimal invasive, and effective treatment for refractory sialorrhea. We described a patient with refractory sialorrhea treated successfully with ultrasound (US) guided percutaneous microwave ablation (MWA).

Associated Abnormalities

Morphological characteristics of 108 cases of uni- and bilateral aplasia of the vertebral artery (VA) in reports or images of retrospective studies, including one recent case, published between 1967 and 2016 are analyzed. Incidence, gender, persistence of carotid-vertebrobasilar anastomosis (CVBA), associated with other vascular variants, and vascular pathology in each group of uni- and bilateral VA aplasia are mutually compared. Most of the cases of VA aplasia in ages 31 to 80 were discovered in USA, Japan, and India. The bilateral VA aplasia is more common in the male gender than in the female one. The side of the VA aplasia had a significant effect on the side of CVBA persistence. Associated aplasia of other arteries was more common in cases of unilateral VA aplasia. The left VA was more commonly hypoplastic in cases of single right VA aplasia than the right VA in cases of single left VA aplasia. Aneurysms of definitive arteries were more frequent in cases of single right VA aplasia than in cases of single left VA aplasia. We claim that the aplasia of the VA probably depends on genetic factors in some races, while diseases are expressed usually in persons over 30 years of age.
