A Study on the Anomalies of Liver in the South Indian Cadavers
Provedor de dados: 77
Autores: Nayak B,Satheesha.
Liver is the largest gland in the body and rarely shows variations in its lobes and fissures. We studied 55 Formalin-fixed livers for occurrence of abnormal shape, lobes, fissures and position of gall bladder. In 60% of cases the liver was normal. 40% livers showed one or the other variations. Additional lobes were found in 9.09% of cases. Additional fissure was found in 1.81% of cases. Presence of dumbbell shaped caudate lobe and presence of large papillary process was noted in 1.81% cases each. In 1.81% cases the fissure for ligamentum teres was absent or situated on the anterior surface of the liver. In 1.81% of cases each the liver was either extremely long or extremely flat. In 18.18% of the cases, the gall bladder was short and its fundus did not...

A Study on the Variations in the Formation of the Trunks of Brachial Plexus
Provedor de dados: 77
Autores: Shetty,Surekha D; Nayak B,Satheesha; Madahv,Venu; Braganza,Cilwyn Shalitha; Somayaji,S. N.
Brachial plexus shows several variations in its formation and branching pattern. Variations in the formation of the trunks are very rare. We studied 44 dissected specimens specifically for variations in the formation of the trunks of the brachial plexus. 5 cadavers (11.3%) showed variations in the formation of the trunks. All the variations were unilateral. In one cadaver (2.27%), the middle trunk was formed by union of C7 and C8 roots and lower trunk was formed by T1 root. Upper and middle trunks were fused with each other in one specimen (2.27%). In 3 specimen (6.81%), the C5 root pierced scalenus anterior before joining C6 to form the upper trunk. Knowledge of its variations is of importance to orthopedic surgeons, neurologists and anesthesiologists.

A Study on the Number and Arrangement of the Structures Passing Through the Porta Hepatis in South Indian Population
Provedor de dados: 77
Autores: Sapna,M; Shetty,Surekha D; Nayak B,Satheesha.
The porta hepatis of the liver is a very important area surgically. The knowledge of the variations in the structures passing through the porta hepatis might be of great help in reducing the risks of surgery in this area. In the current study 59 livers from South Indian cadavers were observed for the number and arrangement of the structures passing through the porta hepatis. In all the livers the portal vein was posteriormost and the hepatic duct was the anteriormost structure. The hepatic artery and its branches were in between the duct and the vein. The mean weight of the liver was 1.025 kg. The mean length of porta hepatis was 4.825 cm and the mean breadth was 2.433 cm. The number varied from one to three for the duct and vein but for the artery it was...

Unusual Branches of Femoral Artery in the Femoral Triangle: A Case Report
Provedor de dados: 77
Autores: Nayak B,Satheesha; Mishra,Snigdha; George,Bincy M; Cherian,Saju Binu; Shetty,Surekha D.
Femoral artery is the major artery of the lower limb. It shows some variations in its branching pattern. One of the rare but clinically important variations is the origin of deep circumflex iliac and inferior epigastric arteries from it instead of from external iliac artery. We report here the origin of inferior epigastric and deep circumflex iliac arteries from the femoral artery bilaterally. Both the arteries passed up deep to the inguinal ligament and had a normal course and distribution after crossing the inguinal ligament. Knowledge of these variations is of importance in plastic surgery, anterior approach to the hip joint, draining psoas abscess or reducing a femoral hernia.

Abnormal Branch of External Iliac Artery in the Iliac Fossa
Provedor de dados: 77
Autores: Nayak B,Satheesha.
An abnormal artery arising from external iliac artery was found during routine dissection class for medical undergraduates. The artery took its origin from the external iliac artery midway between its origin from common iliac and termination as femoral artery. The abnormal artery divided into two branches; an ascending and a descending. The ascending branch supplied iliacus and iliac crest. The descending branch entered the femoral triangle by passing behind the femoral sheath. It supplied the muscles of femoral triangle and anastomosed with medial circumflex femoral artery. The knowledge of this variation may be of use for surgeons doing surgery of femoral hernia.

Role of Dilute Alcohol in the Removal of Fine Wrinkles from Paraffin Sections, a Histo-Technical Study
Provedor de dados: 77
Autores: Kumar,Naveen; Nayak B,Satheesha; Somayaji,S. N; Nayak,Sadananda.
Histotechnology is concerned with processing and preparing of the body tissue in such a manner as to enable a satisfactory study of it. Section cutting is an integral part of histology and histopathology. It is an art by itself requiring skill and knowledge on the part of technician or the person who needs to do section cutting. In the routine method of preparing paraffin sections, it is often encountered by the presence of artefacts like fine wrinkles or folds. Attempts have been made to remove the wrinkles by floating the sections in the warm water bath. However this method has not been able to remove all the wrinkles from the sections. We have designed a simple and reliable method, in which the paraffin sections were floated over the ethyl alcohol...

Communication of the Anterior Branch of the Great Auricular Nerve with the Cervical Branch of Facial Nerve and its Variant Nerve Endings Deep in the Parotid Gland
Provedor de dados: 77
Autores: Rao Sirasanagandla,Srinivasa; Nayak B,Satheesha; Bhat,Kumar M. R; Ravindra S,Swamy.
The communications between the branches of cervical plexus and cervical branch of facial nerve are common and are well known. However, this communication usually occurs between the transverse cervical nerve and cervical branch of facial nerve. During routine dissection classes for the Medical undergraduate students, we came across an anatomical variant of anterior division of great auricular nerve. This variation was found in a 60-year-old male cadaver of South Indian origin and it was unilateral. The great auricular nerve arose from the loop of ventral rami of C2 and C3 spinal nerves and divided into anterior and posterior branches. The anterior branch ran obliquely upwards and forwards on the surface of the sternocleidomastoid muscle along with the...

A Study on the Variations of Size, Shape and External Features of the Spleen in South Indian Population
Provedor de dados: 77
Autores: Nayak B,Satheesha; Somayaji,S. N; Soumya,K. V.
The spleen is the largest lymphoid organ. It is wedge shaped and measures about 1 inch thick, 3 inches broad and 5 inches long. It presents characteristic notches on its superior margin and has a hilum on the visceral surface. The aim was to study the anomalies related to size, shape and external features of the spleen and discuss their clinical importance. As there are not many reports on variations in size shape and features of spleen in the South Indian population, we decided to do this study on cadaveric specimens. We observed 50 spleens fixed with 10% formalin. Among the 50 spleens observed, 25 spleens (50%) were normal and had all the features explained in the textbooks. 25 spleens (50%) did not have any notches on the superior margin, 2 spleens (4%)...

A Classic Case of Annular Pancreas and its Clinical Implications
Provedor de dados: 77
Autores: Nayak B,Satheesha; Mun Yooi,Ooi.
Annular pancreas is a rare developmental anomaly where the head of the pancreas surrounds the second part of the duodenum like a ring. This may cause the duodenal constriction, obstruction, peptic ulcers and other complications. We saw a classic case of annular pancreas. The head of pancreas surrounded the second part of duodenum completely. However there was no narrowing of the duodenum. The case may be of importance for gastroenterologists, surgeons and radiologists.

Looped External Iliac Artery: a Case Report
Provedor de dados: 77
Autores: Nayak B,Satheesha; Kumar,Naveen; Shetty,Surekha D; Guru,Anitha.
Variations of the external iliac artery are very rare. We found a rare variation in the left external iliac artery. The artery was long and formed a characteristic loop. The loop was found in the lesser pelvis in close relation to the obturator nerve. This loop may compress obturator nerve and vessels. The knowledge of this loop might be important for gynaecologists, orthopaedic surgeons and urologists since it may be involved in surgeries of hip, ovary and prostate.
