Introduction: The large number of organs and anatomical structures within the cramped pelvic cavity makes the study of vascular pattern and their variations of much importance in this particular anatomical region. Clear awareness of the vascular anatomy of pelvis is critical in surgeries performed here, which require ligation of the arteries concerned and also because such anomalous origins may cause profuse bleeding during surgical procedures. This is particularly true with regard to the variations in the origin of the obturator artery, while performing pelvic and groin surgeries. Aim: The aim of the present study was to find out the prevalence of normal and aberrant origins of obturator artery and to describe its surgical implications. Materials and Methods: The study was carried out on fifty hemipelvises of embalmed cadavers and the origin and course of the arteries were traced and noted. Results: Of the 50 pelvic halves, in 27 specimens, the obturator took origin from the anterior division of internal iliac artery. Remaining 23 specimens showed variations. The origin of the obturator artery was from the inferior epigastric artery in 11 cases, from the common stem of the internal iliac artery and the external iliac artery in 2 cases each, from the posterior trunk of the internal iliac artery in 5 and one each from superior gluteal, inferior gluteal, and internal pudendal artery. Conclusion: The present study indicates that the origin of the obturator artery is highly variable. It can take origin from the stem of the internal iliac artery or from its anterior or posterior division, or from one of the branches of the divisions. It can also take origin from external iliac artery or its inferior epigastric branch. Advancements in diagnostic and surgical techniques in obstetric procedures and urogenital interventions make it essential to have a clear-cut understanding of the vasculature in the abdomen and pelvis. © 2015, Journal of Clinical and Diagnostic Research.

2015 Journal Article T. T. Sukumaran, Pillay, M., and Gopalakrishnan, A., “An anomalous right subclavian artery with a retrotracheal course: A case report”, Journal of Clinical and Diagnostic Research, vol. 9, pp. AD01-AD02, 2015.[Abstract]

An aberrant right subclavian artery arising as the last vessel of the arch of aorta is an uncommon anatomic anomaly with prevalence reported between 0.2% and 2.0%. In 80% of the cases the aberrant right subclavian artery takes a retro-oesophageal course to the right upper limb. During routine dissection of cadavers for teaching undergraduate medical students an anomalous Retrotracheal right subclavian artery which is a very rare vascular anomaly was encountered in a 35-year-old male cadaver. The artery arose as the last branch of the arch of aorta and coursed to the right between the trachea and oesophagus. The presence of this vascular anomaly could be an unusual cause of dysphagia and breathing difficulty. The clinical significance and embryological aspects of this vascular variant is discussed in this paper. © 2015 Journal of Clinical and Diagnostic Research All rights reserved.

2013 Journal Article S. M. Jacob and Pillay, M., “Variations in the inter-lobar fissures of lungs obtained from cadavers of South Indian origin [Variaciones en las fisuras pulmonares interlobulares de cadáveres del Sur de la India]”, International Journal of Morphology, vol. 31, pp. 497-499, 2013.[Abstract]

The proposed aim of the study was to elucidate the variations of the lung fissures and to correlate their importance in clinics. The study was conducted on 48 lung specimens, 30 right and 18 left, obtained from the cadavers of South Indian origin. Among the right-sided lungs, 2 specimens showed absence of horizontal fissure, and the remaining 25 showed incomplete horizontal fissure. Oblique fissure was incomplete in 15 lungs and one lung showed absence of oblique fissure. An accessory fissure was observed in 4 lungs. Among the left sided lungs, the oblique fissure was incomplete in 7 lungs. The presence of an accessory fissure was found in 5 lungs. With the development of radiological and endoscopic techniques and the advancement of pulmonary surgery, the knowledge of morphological variations of lung fissures is of utmost importance to clinicians to correctly locate the bronchopulmonary segment during pulmonary lobectomy, and for radiologists to correctly interpret X-rays and CT scans.
