Foramen Of Vesalius

Background: Foramen of vesalius is an inconstant foramen that gives passage to an emissary vein that connects pterygoid venous plexus with cavernous sinus. It lies in the anteromedial side of the foramen ovale. Foramen ovale allows the passage for the mandibular branch of trigeminal nerve, the main site for the trigeminal rhizotomy. The presence and description of anatomical variations about the foramen of Vesalius is important during the surgical procedure on the trigeminal nerve which may injure the emissary vein in the foramen leading to intracranial bleeding. Objectives: The aim of the present study is to report the presence and to enlighten the anatomical variations of foramen vesalius which may serve as a guideline for surgeons. Methods: The study was conducted on 100 dry adult human skulls collected from the department of anatomy at Panimalar medical college hospital & research institute Chennai. The skulls were viewed both extracranially and intracranially to identify the presence of foramen of vesalius. The presence and variation of the foramen was noted and discussed. Result: A total of about 200 sides of 100 skulls were studied. Among them 20% of the skull showed presence of foramen of Vesalius bilaterally, 25% unilaterally and one particular skull showed doubled opening on the left side with the presence of a bony septum. This is a rare variation which was less documented in the literature. Conclusion: The knowledge of variations in foramen of Vesalius may help the surgeons for safer planning and execution of the trigeminal rhizotomy technique.

Introduction Knowledge of variations in the cerebral dural venous sinus anatomy seen on magnetic resonance (MR) venography is essential to avoid over-diagnosis of cerebral venous sinus thrombosis (CVST). Very limited data is available on gender difference of the cerebral dural venous sinus anatomy variations Materials and Methods A retrospective study was conducted in NRI medical college in the Department of Radiodiagnosis for a duration of 3 years to study the normal anatomy of the intracranial venous system and its normal variation, as depicted by 3D MR venography, in normal adults and any gender-related differences. Results A total of (46 men, 54 women, age range 12 to 81 years), were included in the study. Most common indication for MR venography was headache (80%). Hypoplastic left transverse sinus was the most common anatomical variation in (25%) patients. Left transverse sinus was hypoplastic in more commonly in male in comparison to females (13 versus 12). Most common variation of superior sagittal sinus (SSS) was hypoplastic anterior one third SSS ,. Conclusion Hypoplastic left transverse sinus is the most common anatomical variation and more common in male compared to female in the present study. Other anatomical variations of dural venous sinuses are not significantly differ among both genders.

Symptomatic Stenosis

Foetal-type posterior circle of Willis is a common anatomical variation with a variable degree of vessel asymmetry. In patients with this abnormality, carotid endarterectomy (CEA) may create cerebral hypo-perfusion intraoperatively, and this may be underestimated under general anaesthesia. There is currently no evidence that anatomical variations in the circle of Willis represent an independent risk factor for stroke. Moreover, there is a paucity of data on treating patients with such anatomical variations and co-existing ICA stenosis. We present a case of CEA under local anaesthesia (LA) in a 52-year-old female patient with symptomatic stenosis of the right ICA and coexistent foetal-type posterior circle of Willis. There were no post-operative complications and she was discharged free from symptoms. She was seen again 3 months later and was free from complications. This case higlights that LA should be strongly considered to enable better intra-operative neurological monitoring in the event of foetal-type posterior circle of Willis.

3135 Background: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is a novel betacoronavirus that causes the respiratory illness coronavirus disease 2019 (COVID-19). COVID-19 ranges in severity from an asymptomatic viral infection to life-threatening cases of pneumonia, acute respiratory distress syndrome (ARDS), multi-organ damage and sepsis. Cancer patients are at an increased risk of severe SARS-CoV-2 infection due to their immunocompromised status. We propose a mechanism by which SARS-CoV-2 infection causes multiple organ damage through IL-6-mediated inflammation and hypoxia-induced cellular metabolic alterations leading to cell death. Hypoxia is also induced by malignancy due to alterations in metabolism, resulting in greater IL-6 secretion. Methods: To highlight the possible effect of active cancer on the likelihood of hypoxia in COVID-19, we analyzed the correlation between cancer status and the severity of COVID-19 from the COVID-19 and Cancer Consortium data registry. For cancer status, we looked at progressive cancer and remission of cancer only -- those being the two extremes of presence and absence of uncontrolled cancer. Similar to prior studies, the severity of COVID-19 was used as an indication of hypoxia. Results: We observed a 24% positive deviation between expected and actual number of patients with actively progressing cancer who had hypoxic COVID-19 (moderate to severe), and a 26.9% negative deviation between expected and actual number of patients with active cancer who had no hypoxia with COVID-19 (p<0.0001). Conversely, for patients with cancer in remission, there was only a +5.8% and -5.1% deviation between expected and actual number of patients who did not have hypoxia and who had hypoxia, respectively. Conclusions: These results suggest that in the presence of poorly controlled malignancy, there is an increased likelihood of hypoxia in patients with COVID-19, thereby exacerbating downstream cytokine release syndrome and contributing to prolonged systemic inflammatory injury. Appreciating this pathway, future therapies can be developed to target the pathogenesis of both diseases and prevent progression, as seen with mesenchymal stem cells, which demonstrated a 91% overall survival and 100% survival in patients younger than 85 years old at one month after a single treatment.[Table: see text]

Background: The purpose of this paper is to describe an anatomical variation of the hand extensor on the little finger of the right hand which receives four tendons, condition unknown, as it is the first case reported so far in the literature. The human extensor tendons of hand often display an array of variations. Awareness of the anatomy and variations of the extensor tendons on the dorsum of the hand is necessary not only for the anatomist but also for surgeons when considering tendons for hand surgery, tendon rerouting or transplants. Materials and Methods: Bilateral anatomical variation in the upper limb was found during routine dissection in a 75-year-old male cadaver in the Morphology Laboratory at the University of Pamplona. The variations were recorded and photographed. Result: In the left hand the extensor digitorum there was a single tendon to the index, double tendon to the middle, triple tendon to the ring finger, a single tendon to the little finger or digiti minimi. The extensor digiti minimi has double tendon. In the right hand the extensor digitorum there was a single tendon to the index, triple tendon to the middle finger, triple tendons to the ring finger, a double tendon to the little finger. The extensor digiti minimi has double tendon. The little finger receives four tendons, 2 of extensor digitorum and 2 of extensor digiti minimi. The dorsum of the left hand and right showed juncturae tendinum type 2, between the extensors tendons in the 3rd intermetacarpal space; type 3, between the extensors tendons in the 4th inter metacarpal space. Conclusion: The presence of multiple tendons may alter the kinematics around the site of attachment to the phalanx. Knowledge of anatomical variations and normal anatomy of the extensor tendons, may be helpful while performing graft and tendon transfer operations.Bangladesh Journal of Medical Science Vol.15(2) 2016 p.278-282

Abstract Background and aims: The abdominal aorta usually terminates at the level of L4 vertebral body into common iliac arteries. With the present day advancements in vascular surgery and neurological surgeries involving approach to lumbar vertebral bodies, we need to know any variations from this normal course. So, the present study aimed at knowing the anatomical variations in the termination of abdominal aorta and in common iliac arteries which might prove to be of some help in some of such surgeries. Material and methods: The study was conducted on 35 adult (29 males and 6 females) embalmed cadavers obtained from anatomy departments of Govt. Medical college, Amritsar and Gian Sagar Medical college, Ramnagar, Punjab. The abdominal cavity was opened, peritoneum stripped off from aorta at its bifurcation, variations in its termination, common iliac arteries and their branches were carefully observed and recorded. Results: In 54.29% cases the level of aortic bifurcation was found opposite 4th Lumbar vertebra, in the rest it was variable between L3 and L5 vertebra. Conclusions: These variations may lead to some trouble during vertebral surgeries, making it essential to investigate and locate the exact position of great vessels before the commencement of surgery.

Transmission And Distribution

Sacroiliac (SI) joint is the articulation which forms the part of the bony pelvis. It plays an important role in locomotor activity, and childbirth during labour. It helps in the transmission and distribution of axial body weight from the spine to the pelvis. This synovial joint exhibit limited gliding movements within the joint cavity. About 15-30% of low backache aetiologies are attributed to SI joint dysfunction. People who are overweight, have co-morbid conditions, and pregnant women are at higher risk of developing vertebral joint deformities called spondylarthropathies. They are group of inflammatory disorders which are involving the vertebral spines and peripheral joints, where the symptom of stiffness is prominently seen. The anatomical variations in the SI joint morphology like accessory SI joint, iliosacral complex and sacral defect, dismorphic joint, are of compelling interest concerning SI joint pathologies from the orthopaedic viewpoint. This case report presents a bilateral fusion of SI joint, found in a skeleton in the museum of medical college.
