Abstract: The main purpose of this study was to convey a more precise explanation of the arterial supply of the intestinal tract of the goat. Fifteen adult healthy goats were used. Immediately after slaughtering of the goat, the thoracic part of the aorta (just prior to its passage through the hiatus aorticus of the diaphragm) was injected with gum milk latex (colored red) with carmine. The results showed that the duodenum was supplied by the cranial pancreaticoduodenal and caudal duodenal arteries. The jejunum was supplied by the jejunal arteries. The ileum was supplied by the ileal; mesenteric ileal and antimesenteric ileal arteries. The cecum was supplied by the cecal artery. The ascending colon was supplied by the colic branches and right colic arteries. The transverse colon was supplied by the middle colic artery. The descending colon was supplied by the middle and left colic arteries. The sigmoid colon was supplied by the sigmoid arteries. The rectum was supplied by the cranial; middle and caudal rectal arteries. Keywords: Anatomy,Arteries, Goat, Intestine I.

  • THE ARTERIAL SUPPLY of the HUMAN PROSTATE and SEMINAL VESICLES by E
    [ 209 ] THE ARTERIAL SUPPLY OF THE HUMAN PROSTATE AND SEMINAL VESICLES By E. J. CLEGG Department of Anatomy, University of Liverpool INTRODUCTION Much of the difficulty experienced in evaluating and comparing work on vascular anatomy is a result of lack of uniformity in nomenclature, and the literature on this particular region of the arterial system is no exception. Previous workers appear to be divided on the question of the existence of a specific artery to the prostate gland (Kraas, 1935; Awataguti, 1939), but the measure of agreement is greater than would appear from a superficial survey of the literature, and differences in results may be explained as resulting from differences in ter- minology, rather than from fundamental anatomical variations. The object of this report is to describe in some detail the blood supply to the human prostate and seminal vesicles, to compare the various systems of nomen- clature used by previous workers, and to provide an accurate representation of the vascular patterns as a basis for surgical practice. MATERIALS AND METHODS Fresh post-mortem material was used whenever possible, the ages of the subjects varying between 36 and 64 years. In no case did the prostate show pathological hypertrophy. After ligating the common and external iliac arteries close to their origin the former was cannulated distally, and an injection of 10-15 ml. of a radio-opaque medium ('Micropaque'; Damancy and Co. Ltd) was made. This injection mass com- bines high density for radiographic purposes with good colour contrast for dissection. The injection was made at pressures varying from 100 to 200 mm.

Study of middle rectal artery was undertaken as it is important in surgeries of rectal carcinoma. Materials and Methods For the present study, 40 pelvises, fixed in 10% formalin, were procured from the Department of Anatomy of Dr. D. Y. Patil Medical College, Pune, Maharashtra, India. Sagittal section of pelvis was taken and dissection was per- formed following the steps according to the Cunningham’s manual. Results Variations were found in the origin of middle rectal artery such as those arising from the internal pudendal artery in nine cases. In two cases, it was arising from the common stem of internal pudendal and inferior gluteal arteries. It was seen arising from the inferior vesical artery in one case, while in two cases the middle rectal Keywords artery was arising from the obturator artery. ► middle rectal artery Conclusion This is the artery that penetrates the fascia of the rectum which is ► variations important in mesorectal excision in cases of rectal carcinoma.

  • Multiple Variations in the Pelvic Vasculature – a Case Report Anatomy Section
    DOI: 10.7860/JCDR/2015/10775.5526 Case Report Multiple Variations in the Pelvic Vasculature – A Case Report Anatomy Section SATHEESHA B NAYAK1, SUREKHA D SHETTY2, SRINIVASA RAO SIRASANAGANDLA3, VasanTHAKUMAR P4, RAGHU JETTI5 ABSTRACT A thorough knowledge of possible variations of pelvic vasculature is very useful for surgeons, gynaecologists, radiologists, urologists and orthopaedic surgeons. We report multiple vascular variations in the left half of the pelvis of an adult male cadaver. Iliolumbar artery arose from the main trunk of the internal iliac artery. Posterior division of the internal iliac artery gave two lateral sacral arteries and a superior gluteal artery. The anterior division of the internal iliac artery gave origin to superior vesical, inferior vesical, inferior gluteal and internal pudendal arteries. The internal pudendal artery gave origin to a common trunk before leaving the pelvis. The common trunk divided into middle rectal artery and deep artery of the penis. The obturator artery took origin from the inferior epigastric artery and descended downward to the pelvis and left the pelvis by passing through the obturator foramen. Most of the other veins accompanying the arteries joined to form a plexus on the superior surface of the pelvic diaphragm. This plexus condensed to form anterior and posterior divisions of the internal iliac vein. Apart from this, the posterior part of the plexus drained directly into the common iliac vein through a large unnamed vein. Keywords: Deep artery of penis, Internal iliac artery, Internal iliac vein, Internal pudendal artery, Obturator artery CASE REPORT Internal iliac artery frequently shows variations in its branching pattern During dissection classes for undergraduate medical students, we classified into different types by previous studies.
