of variations will be help in localizing the appendix during an emergency appendicectomy operation Aim of the study: To determine the frequency of the various positions of the appendix, the average length, and breadth and extent of mesoappendix.
Conflicts of interest
• To determine the frequency of shape of caecum in both sex. • To find out the average distance of appendicular orifice to ileocaecal orifice correlate the same with the previous author’s.

Materials and methods: Study was carried out on 20 adult cadavers (male – 13, female – 7). The cadavers were obtained from the Department of anatomy, Krishna Institute of Medical Sciences Deemed University, Karad. Maharashtra. Direction of the tip of the appendix with its length, breadth and position were tabulated. One “Horseshoe shaped” appendix in male cadaver was found these excluded from study. So final study was carried on 19 cadavers (male – 1 2, female – 7). Results and observation: The position of caecum and vermiform appendix in adult cadavers was found to be in the right iliac fossa in both sex. Average length of vermiform appendix was 5.42 cm (in males – 5.13 cm and 5.71 cm in female). Average breadth of vermiform appendix at the level of base was 2.1 mm in 15.7% of cadavers meso-appendix failed to reach appendicular tip. Average distance of appendicular orifice from ileocaecal orifice was 1.80 cm. (In males it was 1.70 cm and in females it was 1.91 cm). Most common shape of caecum was adult 68.4% exaggerated 15.8%, fetal 10.5% and infantile 5.3%.

Splenomesenteric trunk-computed tomographic study C.S. Ramesh Babu ∗ , O.P. Gupta Muzaffarnagar Medical College, Muzaffarnagar, India Background: Splenic artery is a relatively constant branch of celiac trunk and its variations are rare. One of the rarest variations is the occurrence of splenomesenteric trunk, common origin of splenic and superior mesenteric arteries, with an occurrence rate of less than 1.0%. Materials & methods: We present here incidental observation of splenomesenteric trunk in three patients while retrospectively analysing contrast enhanced computed tomographic scans of 960 patients (491 males and 469 females). Observations: The splenomesenteric trunk was observed in two male and one female patient with an incidence of 0.31%. Common hepatic and left gastric arteries were arising as a common hepatogastric trunk. In one male patient the splenic artery originating from the splenomesenteric trunk was giving rise to inferior pancreaticoduodenl artery. Discussion: Presence of splenomesenteric and hepatogastric trunks represents a variant anatomy of both celiac trunk and superior mesenteric arteries classified as Type IVIII of Morita’s classification. Combined review of 36 studies involving a total of 9829 cases by Panagouli et al. (2013) revealed the occurrence of splenomesenteric trunk in 0.09% cases (9/9829 cases). Splenic artery from splenomesenteric trunk has a variable relationship with pancreas and the splenic vein. Visceral artery aneurysms affect splenic artery in about 60% cases and the aberrant splenic artery may also develop aneurysms close to its origin.
Sireesha Barika Andhra Medical College, Visakhaptnam, India Introduction: The traditional definition of superficial palmar arch consists of anastomosis between the superficial palmar branches of the radial and ulnar arteries. The study of superficial palmar arch and its variations has been reported rarely. And the purpose of the study is to provide assessment of anatomical variations in superficial palmar arch. Materials and methods: A total of about 20 upper limbs have been dissected which were obtained from Andhra Medical College, Visakhapatnam, out of which 15 males and 5 females aged between 50 and 80 years and the vascular pattern of superficial palmar arch has been studied. Results: The complete formation of superficial palmar arch was found in 18 and 2 hands showed incomplete arch. This indicates that the incidence of complete and incomplete formation of superficial palmar arch are 95% and 5% respectively. Conclusion: The variations found in the study will help not only to the anatomists but also microvascular and orthopedic surgeons. The understanding of variant arterial arches is helpful in microsurgical procedures like reconstructive hand operations.

Akshay, Chandni Gupta, Sneha Guruprasad, Antony Sylvan D’Souza, K.V. Rajagopal Kasturba Medical College, Manipal, India Introduction: The brain undergoes many gross and pathological changes with advancing age, and also in various dementias, with regression of brain tissues. Ventricular enlargement is a sensitive indicator of cortical atrophy due to increasing age and dementia. The dimensions of the third ventricle also enlarge in various types of hydrocephalus. Aim/Objective: The aim of present morphometric study is to examine the range of dimensions of the normal third ventricular cavity and its variations with age and sex.
