PMID: 18830532

Peritoneal anomalies are common in humans. We report the presence of a cystogastrocolic fold associated with an abnormally small gallbladder in a 50-year-old male cadaver. Presence of this fold is one of the clinically important anomalies, which can result in atrophy of the gallbladder or congenital obstruction of the duodenum.

Variations in the arterial pattern of the upper limb have been observed frequently, either in the routine dissections or in clinical practice. The aim of the present study was to describe the anatomical, surgical and embryological importance of major arteries of upper limbs of human beings. The present article is the report of low division and trifurcation of brachial artery and abnormal course of radial artery (passing deep to the pronator teres muscle) found in a 45-year-old embalmed male cadaver. Knowledge of the arterial variations in the upper limb is of considerable importance during invasive and non-invasive investigative procedures or orthopedic, reconstructive, or surgical procedures.

Fulltext Anomalous superficial peroneal nerve and variant cutaneous innervation of the sural nerve on the dorsum of the foot: a case report

The superficial peroneal nerve is a branch of common peroneal nerve. There are reports about the variant course and distribution of this nerve. The sural nerve arises from the tibial nerve in the popliteal fossa. The variations of the above nerves described here are unique and provide significant information to surgeons dissecting lower limb.

Unusual origin of radial collateral artery noted in quadrangular space syndrome

Mohandas Rao KG, Bhat SM, Vollala VR

J Chin Med Assoc, 2006 Jun;69(6):276-7.

PMID: 16863014

In this paper, an unusual origin of the radial collateral artery of the arm is reported. The radial collateral artery in one of the cadavers dissected by us originated from the posterior circumflex humeral artery. The importance of this abnormal origin of the radial collateral artery from the posterior circumflex humeral artery in quadrangular space syndrome is discussed.

Fulltext Multiple accessory structures in the upper limb of a single cadaver

Vollala VR, Nagabhooshana S, Bhat SM, Potu BK, Rakesh V

Singapore Med J, 2008 Sep;49(9):e254-8.

PMID: 18830534

The arterial and muscular variations of the upper limbs are common but important with regard to surgical approaches. Even though anomalies of the coracobrachialis muscle are rare, anatomical variations of the biceps brachii, existence of the accessory muscles in the forearm and persistent median artery are known and well documented. During routine dissection, we observed some important anatomical variations in a 50-year-old male cadaver. The variations were unilateral. The anomalies were: third head for biceps brachii muscle, an accessory belly for coracobrachialis muscle crossing the median nerve and brachial vessels and continuing with the medial head of triceps brachii muscle to be inserted to the olecranon process (coracoulnaris), a persistent median artery and an additional muscle in the anterior compartment of forearm. Although there are individual reports about these variations, the combination of these variations in one cadaver has not previously been described in the literature. Awareness of these variations is necessary to avoid complications during radiodiagnostic procedures or surgeries in the upper limb.

Fulltext Unorthodox superficial palmar arch observed in a South Indian cadaver: a case report

Vollala VR, Nagabhooshana S, Rao M, Potu BK, Pamidi N, Bolla SR

Cases J, 2009;2:6362.

PMID: 19829795 DOI: 10.4076/1757-1626-2-6362

Variations in formation of the superficial palmar arch are common. A classic superficial palmar arch is defined as direct continuity between the superficial branch of the ulnar artery and superficial palmar branch of the radial artery. During routine dissection classes to undergraduate medical students we have observed formation of superficial palmar arch solely by superficial branch of ulnar artery without any contribution from the radial artery or median artery. Knowledge of the anatomical variations of the arterial pattern of the hand is crucial for safe and successful hand surgery.

Multiple arterial, neural and muscular variations in upper limb of a single cadaver

Vollala VR, Nagabhooshana S, Bhat SM, Potu BK, Rodrigues V, Pamidi N

Rom J Morphol Embryol, 2009;50(1):129-35.

PMID: 19221659

During routine dissection classes to undergraduate medical students, we have observed some important anatomic variations in the right upper limb of a 45-year-old cadaver. The anomalies were superficial ulnar artery, persistent median artery, variant superficial palmar arch, third head for biceps brachii, accessory head for flexor pollicis longus, variant insertion of pectoralis major, absence of musculocutaneous nerve, coracobrachialis muscle supplied by lateral root of median nerve and anomalous branching of median nerve in arm and forearm. Although there are individual reports about these variations, the combination of these variations in one cadaver has not previously been described in the literature consulted. Awareness of these variations is necessary to avoid complications during radiodiagnostic procedures or surgeries in the upper limb.

Rare anatomical variant: arterial circle in palm and at the base of the thumb

Vollala VR, Nagabhooshana S, Bhat SM, Rodrigues V, Rao M, Pamidi N, et al.

Rom J Morphol Embryol, 2008;49(4):585-7.

PMID: 19050813

In this article, we describe anomalous formation, distribution of superficial palmar arch and an arterial circle at the base of the thumb found during routine dissection classes in the right hand of a 45-year-old male cadaver. These variations are unique and provide significant information to surgeons dissecting the hand region.

Fulltext Bilateral variant testicular arteries with double renal arteries

Sylvia S, Kakarlapudi SV, Vollala VR, Potu BK, Jetti R, Bolla SR, et al.

Cases J, 2009 Feb 02;2(1):114.

PMID: 19187540 DOI: 10.1186/1757-1626-2-114

BACKGROUND: The testicular arteries normally arise from the abdominal aorta. There are reports about the variant origin of these arteries. Accessory renal arteries are also a common finding but their providing origin to testicular arteries is an important observation. The variations described here are unique and provide significant information to surgeons dissecting the abdominal cavity.

CASE PRESENTATION: During routine dissection classes of abdominal region of a 60-year-old male cadaver, we observed bilateral variant testicular arteries and double renal arteries.

CONCLUSION: Awareness of variations of the testicular arteries such as those presented here becomes important during surgical procedures like varicocele and undescended testes.
