Anomalous origin of inferior pancreatico-duodenal artery: A case report
S80
Abstracts / Journal of the Anatomical Society of India 66S (2017) S79–S125
Material and methods: While doing routine dissection for postgraduate studies at PGIMER Chandigarh, we came across a cadaver with unusual innervations of infrahyoid muscles. The structures were dissected properly and relevant photographs taken. Observations: Vagus and hypoglossal nerve after emerging from the skull base form single nerve trunk (13.6 mm length and 4.38 mm diameter). Ventral rami of first cervical spinal nerve join the common trunk 6.12 mm below the tip of styloid process. Second cervical spinal nerve join vagal trunk 8.77 mm above greater cornua of hyoid bone while third cervical spinal nerve join at the level of greater cornua. Results: Superior belly of omohyoid and thyrohyoid were supplied by fibres from hypoglossal nerve. Sternohyoid, sternothyroid and inferior belly of omohyoid were supplied by fibres from vagus nerve. Conflicts of interest The authors have none to declare. http://dx.doi.org/10.1016/j.jasi.2017.08.249 4 Anomalous origin of inferior pancreatico-duodenal artery: A case report Rakhee Sharma
5 A cadaveric study of bilateral variation in the origin of obturator artery Sanjay Joseph Fernandes Father Muller Medical College, Mangalore, Karnataka, India Introduction: The obturator artery usually arises from the anterior division of the internal iliac artery. Variations in its origin, can lead to unnecessary exploratory surgery and complications, during laparoscopic herniorrhaphy procedures. Aim: The aim of the present study, is to observe the variations in the origin of the obturator artery. Material and methods: Forty adult human pelvic halves of known sexes were studied, to note down the variations in the origin of the obturator artery. Photographs were taken to document the variations. The study design was an observational study. Sample 2 size was calculated by using the formula: n = Zalpha p(1 − p)/e2 . Results: In 39 (97.5%) of the specimens, the obturator artery, was found to be arising normally, from the anterior division of the internal iliac artery, whereas in one (2.5%) of the specimens, it was found to be arising bilaterally, from the posterior division of the internal iliac artery. Conclusion: A good knowledge about the normal anatomy and the variations in the origin of the obturator artery is essential, as it reduces the surgical complications during pelvic surgeries.
University College of Medical Sciences, Jodhpur, India Introduction: Awareness of new aspects of vascular anatomy of the pancreatic region is required for further improvement of surgical procedures. Knowledge of variations in the arteries supplying duodenum and pancreas can help in minimizing the blood loss during surgery. Therefore anomalous origin of inferior pancreaticoduodenal artery as one of the terminal branches of celiac trunk is being reported. Material and methods: Routine anatomical dissection in the supramesocolic compartment of an embalmed adult male cadaver of approximately 67 years of age was done which revealed an abnormal origin of inferior pancreatico-duodenal artery. Observation: The inferior pancreatico-duodenal artery was arising from the celiac axis as one of the terminal branches along with splenic and common hepatic arteries. After its origin the inferior pancreatico-duodenal artery was forming an arcade with the branches of superior pancreatico-duodenal artery along the head of pancreas while coursing inferiorly, behind the body and neck of the pancreas. Conclusion: While performing surgeries in the supramesocolic compartment, the surgeons must be aware of anomalous origin of inferior pancreatico-duodenal artery so as to avoid torrential bleeding leading to vascular catastrophe.

Identification of arterial variation related to the thyroid gland is of immense importance in formulating planned surgical approaches to the thyroid gland in alerting the surgeons to avert inadvertent injuries to the vital anatomical structures in this area. Case report: The thyroideaima artery was found during routine dissection that arose from the brachiocephalic trunk. After arising it ascended in front of trachea and entered in the isthmus of the thyroid gland. Conclusion: The possible existence of this anomaly is important in neck surgeries especially in tracheostomy. If unrecognized it can be a source of brisk uncontrolled bleeding during or after surgery. Conflicts of interest The author has none to declare. http://dx.doi.org/10.1016/j.jasi.2017.08.252
