The Sciatic Nerve after originating from sacral plexus leaves the pelvis through the lower part of greater sciatic foramen into the gluteal region and divides into two components at any level from its origin to its usual division inside the upper part of popliteal fossa. The Present study was conducted in the Department of Anatomy Government Medical College Srinagar to study the variations in the level of division of the sciatic nerve during usual dissection for academic purposes. Both lower limbs of a middle aged formalin preserved Indian male cadaver were dissected out for routine teaching and simultaneously recording observations. It was observed that the left sided sciatic nerve divided into its two components inside the pelvis. The tibial and common peroneal nerves after leaving through greater sciatic foramen sandwiched piriformis muscle in the gluteal region. The common peroneal nerve passed above the piriformis where as the tibial nerve passed inferior to this muscle. The sciatic nerve on the other side of this cadaver followed the normal anatomical course. The higher division of sciatic nerve inside the pelvis though rare is of great academic and clinical significance in Neurology, General Surgery, Orthopaedics, Anaesthesiology, Sports medicine and physiotherapy. The knowledge of this variation is also important for paramedics who frequently give intramuscular injections into the gluteal region.
The Present study was conducted in the Department of Anatomy Government Medical College Srinagar to observe the variations in the branching pattern of facial artery. The aim of this study was to make clinicians academically wiser and practically more competent while dealing with these anomalous branches during surgery and other interventional procedures. Bilateral head and neck dissection of a formalin preserved middle aged Indian male cadaver was done for routine teaching and simultaneously observations regarding the branching pattern of facial artery were recorded. It was observed that left facial artery gave an anomalous branch mid-way between the masseter and inferior labial artery. This anomalous branching pattern of facial artery though rare is of great academic and clinical significance in general practice, Otorhinology, Traumatology, Plastic and Maxillofacial surgery. These anomalies should be kept in mind and given due honour while operating and intervening in the region of face for emergency management of injuries, correction of congenital anomalies and while performing other general and specialized surgical procedures in this region.
Introduction: Liver receives dual blood supply from hepatic artery and portal vein. Venous blood from Liver to inferior vena cava is drained by three hepatic veins. The number, pattern and mode of termination of hepatic veins into inferior vena cava is not always same. Variations in number, pattern and positions of the hepatic veins and their mode of termination do exist which significantly influence surgical interventions on liver especially during transplantation. Materials and Methods: 28 wet formalin preserved specimens were taken for the present study. A longitudinal incision was given in the inferior vena cava to observe the number, pattern and arrangement of hepatic veins openings into inferior vena. The specimens were preserved after routine dissection classes Result: 19 livers of 28 (67.86%) were found to be drained by three major hepatic veins, whereas 9 livers out of 28 (32.14) presented with accessory hepatic veins in addition to major hepatic veins. The number of accessory veins ranged from 1-3. Out of the nine specimens with accessory hepatic veins seven (77.77%) presented with three plus one pattern (3 major hepatic veins 1 accessory hepatic vein).Three plus two and three plus three pattern was observed in one specimen each (11.11%). The arrangement of three major veins from left to right was left hepatic, middle hepatic and right hepatic. The openings of all accessory veins were found below the openings of major hepatic veins. Conclusion: A sound knowledge of Accessory hepatic veins and their pattern is essential for Radiologists and also for liver transplant surgeons to reduce postoperative complications.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
