Primary Pattern

AbstractA detailed description of the vascular pattern of upper limbs especially their variations in their origin, course and branching pattern is of utmost importance anatomically in general and clinically in particular. These variations have drawn attention of surgeons, physicians, radiologist and interventionists due to the advanced surgical procedures practicd in vascular surgeries, plastic (reconstructive) surgeries and also for diagnostic and therapeutic approaches. 50 cadavers (100 upper limbs) were used for the study, which were dissected as the part of routine dissection for teaching undergraduate students at our institution. Length of the normal and variant arteries with mean, standard deviation, 'p' and 't' values are noted in each of the limbs. The following variations are observed - i) high division of brachial artery ii) higher origin of profunda brachii artery, iii) high origin of radial artery, iv) absence of common interosseous artery. The variations are of particular importance to the surgeons operating in the area, especially for those involved in vascular reconstructive surgeries. So it is prudent to do pre-operative studies of the brachial and antebrachial arteries and their branching patterns, to prevent possible complications post operatively.

AbstractDuring routine dissection of a cadaver alloted to the undergraduate students in the department of anatomy in SN Medical College, Bagalkot, the authors found multiple variations in the branching pattern of brachial, ulnar and radial arteries. There was high division of brachial artery into ulnar and radial arteries. The profunda brachii originated from brachial artery as usual while superior and inferior ulnar collateral arteries originated from ulnar artery. The radial artery gave origin to common interosseous artery which further divided into anterior and posterior interosseous arteries. All the three arteries i.e. brachial, ulnar and radial were considered as superficial arteries as they were superficial throughout the course. These observations of vascular anomalies are of clinical significance to vascular and plastic surgeons.

Introduction: Conventional knowledge of the brachial artery, the principal artery of the upper limb & its branches has played a major role in vascular surgeries. Literature along with various cadaveric & clinical studies suggest that brachial artery vary widely in origin, course and branching pattern. The great variability of this arterial pattern may be attributed to the failure of regression of some paths of embryonic arterial trunks. Anatomical knowledge of this principal artery and its variations has many clinical implications especially in surgeries related to orthopedic and vascular re-constructive procedures. MATERIALS AND METHODS: The present study was conducted on 56 upper limbs of different age group and sex (19 Male and 9 Female) The brachial arteries were identified and branching pattern and relations of the brachial artery with brachial plexus in arm was observed and presence or absence of variations were documented. Results: Out of 56 upper limbs studies, 53 (94.64%) limbs showed normal morphological pattern of brachial artery, 3 (5.35%) limbs showed superficial brachial artery, 1 limb (1.78%) showed tortuous and SBA with trifurcation into radial artery, ulnar artery and common interosseous artery in the cubital fossa. Conclusion: The study of Brachial artery and variation in its course and branching pattern is clinically important for surgeons, ortho-paedicians operating on the supracondylar fracture of humerus and radiologists performing angiographic studies on the upper limb. KEY WORDS: Common Interosseous Artery, Median Nerve, Superficial Brachial Artery, Trifurcation, Ulnar Artery.

BACKGROUND Superior Mesenteric Artery (SMA) is one of the anterior branches of the abdominal aorta. It originates from abdominal aorta at the level of lower border of first lumbar vertebra, one centimeter below the coeliac trunk. It gives the first branch inferior pancreaticoduodenal artery (IPDA), The colic branches arise from concave right side of the superior mesenteric artery, these are middle colic artery (MCA), right colic artery (RCA), ileo colic artery (ICA). Jejunal and ileal branches arise from left side of the SMA. Superior mesenteric artery supplies derivatives of midgut. Knowledge of branching pattern of the SMA is clinically important to gastroenterologists operating on gut and neighboring structures like pancreas, duodenum, and liver. We wanted to study the variations in the branches of superior mesenteric artery. METHODS This is a descriptive study conducted on 50 adult embalmed human cadavers by conventional dissection method, the findings were noted and tabulated. RESULTS Present study shows that inferior pancreatic duodenal artery orginated from SMA in 47 (94 %) specimens. IPDA was absent in 3 (6 %) specimens. Middle colic artery was found to arise from SMA in 48 (94 %) and MCA was absent in 2 (4 %) specimens. Right colic artery was found to arise from SMA in 47 (94 %) specimens and it was absent in 3 (6 %) specimens. Ileo-colic artery was found to arise from SMA in all 50 (100 %) specimens. CONCLUSIONS Awareness of these complex variations may prevent devastating complications during colonic surgeries. Variations in the branching pattern of superior mesenteric artery is essential for surgeons operating on derivatives of midgut, liver, pancreas.

Background: Marginal Mandibular nerve, a branch of facial nerve, emerges at the lower part of the anterior border of parotid gland. It supplies risorius, muscles of lower lip and chin and joins mental nerve. This nerve has an important relationship with the lower border of mandible and is likely to be damaged during procedures in or around the submandibular area and can lead to certain morbid conditions like deviation of angle of mouth, drooling of saliva and difficulty in phonation.Methods: Sixty formalin preserved specimens of head and neck were used for studying the branching pattern of marginal mandibular nerve. The present study was conducted in the department of Anatomy Govt Medical College Srinagar over a period of two and a half years from 2015 to 2017. Cadaveric dissection was also used in the study during the routine teaching of undergraduate MBBS and BDS students in the department. The photographs of the variations seen during the study were taken.Results: In Forty-seven specimens (78.33%) there was a single branch of marginal mandibular nerve, in 10 specimens (16.6%) there were two branches of marginal mandibular nerve and in three specimens (5.0%) the marginal mandibular nerve was having three branches.Conclusions: From the above study it was concluded that marginal mandibular nerve can have two or three branches. Therefore, it is advisable to take due care during surgical procedures in the lower part of face and upper part of neck to preserve marginal mandibular nerve and to ensure cosmesis and prevent morbidity.

Abstract Variation in branching pattern was studied in six Virginia group peanut cultivais (ssp. hypogaea var. hypogaea). Lines with genetically distinct branching patterns differing from the normal pattern were readily found in two of the cultivars. These variable lines showed no yield advantage over the normal lines. It was concluded that there is considerable genetic variation for branching pattern in Virginia peanuts. The variation could be ascribed to a range of modifier genes which can change the normal pattern of branching. There were indications of a strong environmental effect on branching pattern and of a genotype by environment interaction.

Introduction The musculocutaneous nerve and the median nerve are branches from the lateral cord of the brachial plexus with a root value of C5, C6, and C7. The medial root of the median nerve is a branch of the medial cord. The present study aims at observing any variations in these peripheral nerves, so that this knowledge can be utilized by surgeons, anesthesiologists, and orthopedicians during surgical procedures and nerve block. Materials and Methods The present study was carried on 30 adult embalmed cadavers (60 upper limbs) in the department of anatomy of the Kasturba Medical College , Manipal, India. The infraclavicular part of the brachial plexus was dissected, and any anatomical variations in the formation and in the branching pattern of the musculocutaneous nerve and of the median nerve were noted and photographs were taken. Results The median nerve was noted to be formed from 3 roots in 8 out of 60 dissected upper limbs (13.33%). The musculocutaneous nerve was absent in 5% of the dissected limbs, and communications between these 2 nerves were noted in 13.33% of the dissected limbs. Conclusions Noted variations of the nerves may be of help to surgeons operating in the axillas and in the arms.

Abstract Background and aims: Kidneys are the pair of excretory organs situated retroperitoneally in the lumbar region on either side of vertebral column. Classically there is a single renal artery supplying each kidney which arises from abdominal aorta. Understanding the anatomy of vascular pattern of kidney is important for clinicians to perform renal transplantation, interventional radiological stodies. The present stody was undertaken for studying the prehilar vascular pattern of renal artery. Material and methods: Kidneys were collected from the department of Anatomy, Navodaya Medical College and Hospital, Raichur, Karnataka. Totally 84 kidneys were collected, the kidney containing full renal arteries from aorta were selected. The abnormal shaped kidneys were excluded from the stody. The blunt dissection was done to remove fat, loose connective tissue at the hilum and the artery was coloured with fabric red colour and photographed. Results: Out of 84 kidneys, single renal artery was seen in 72 cases and 12 kidney specimens showed double renal arteries. The single renal artery divided into anterior and posterior divisions. The anterior division was classified into three types of which, type I showed 43.06% incidence, type II showed 33.33% and type III showed 23.61% incidence. The posterior division was classified into two types of which type I showed 69.44% and type II showed 30.56%. Superior polar arteries were seen in 13.09% and inferior polar artery was seen in 5.95% cases. Conclusion : A sound knowledge of branching pattern of renal artery is important for urologists and radiologists for giving proper diagnosis and treatment. The present study mainly aims for prehilar vascular pattern of renal artery which may be usefull for renal transplantation and microvascular surgeries of kidneys.

The palmar communicating branch between the median and ulnar nerves was investigated in 98 hands with the aim of outlining its most common branching patterns and describing its relationship to well-defined anatomical landmarks, including the bistyloid line, wrist crease and flexor retinaculum. Five branching patterns were identified and classified based on their proximal and distal attachments. The palmar communicating branch was found to lie between 26%–79% of the total distance between the metacarpophalangeal joint of the long finger and the wrist crease, and 35%–75% of the total distance between the metacarpophalangeal joint of the long finger and the middle of the bistyloid line. With the aid of the morphometric indices obtained from this study, a risk area where the palmar communicating branch is most likely to be found is outlined. Knowledge of the branching patterns and location of the palmar communicating branch can help clinicians to better assess variations in the patterns of sensation, preserve the nerve during surgical interventions to the palm and better assess post-operative complications involving the branch.
