Introduction: Vascular compromise causes hand pain, and physical examination requires to differentiate vascular causes from isolated ulnar nerve compression. Diagnostic studies visualize vascular abnormalities such as CT scans, MRA scans, and AV fistulograms. Ulnar artery aneurysms are quite rare discoveries, related to repetitive trauma, vasculitis, anatomic abnormalities, or infections. It is...

AIM We report a case of ulnar and palmar arch artery aneurysm in a 77 years old man without history of any occupational or recreational trauma, vasculitis, infections or congenital anatomic abnormalities. We also performed a computed search of literature in PUBMED using the keywords "ulnar artery aneurysm" and "palmar arch aneurysm". CASE REPORT A 77 years old male patient was admitted to hos...

The word “Brachial” is derived from the Greek word Brakion meaning ‘shorter’; brachium also means arm [1]. Normally brachial artery is a continuation of axillary artery at the inferior border of teres major muscle in axilla. Towards the distal end, it lies medial to the bicipital aponeurosis. At the level of neck of radius, in cubital fossa, artery bifurcates into two terminal branches, mediall...

Cubital tunnel syndrome is often accompanied by paresthesia in ulnar nerve sites and hand muscle atrophy. When muscle weakness occurs, or after failure of more conservative treatments, anterior transposition is used. In the present study, the ulnar nerve and its blood vessels were examined in the elbows of 18 adult cadavers, and the external diameter of the nutrient vessels of the ulnar nerve a...

Variations in the main arteries of the upper limb are common and these anomalies can be of substantial interest to orthopedic surgeons, plastic surgeons, radiologists and anatomists. We present here a case of a high origin of the ulnar artery from the brachial artery found during anatomical dissection of a right upper limb of a 50-year-old man. This superficial ulnar artery, after running over ...

Introduction Brachial artery is the continuation of axillary artery at the lower border of teres major muscle. It gives profunda brachii, nutrient artery to humerus, superior and inferior ulnar collateral arteries and muscular branches in the arm. It ends by dividing into radial and ulnar arteries at the neck of radius. Radial and ulnar arteries descend in the forearm pursuing a typical course ...

A subcutaneous pedicle ulnar flap used to cover a skin defect around the wrist is reported. Unlike the standard ulnar flap, which is isolated around the dorsal branch of the ulnar artery and its associated veins, this flap is based on the ascending branch of the dorsal branch of the ulnar artery more proximally to obtain a longer vascular pedicle. A subcutaneous pedicle flap that contained the ...

INTRODUCTION Superficial palmar arch (SPA) is dominant vascular structure in palm of hand. In present study we described a case of Ulnar / Radiopalmar pattern of incomplete SPA in an Iranian cadaver. When the SPA is complete, the superficial palmer branches of the radial artery contribute to the ulnar artery. In incomplete type of SPA, there was no anastomosis between the ulnar and radial arter...

variations in arterial anatomy are less frequent, contrary to the venous system, and most of these variations affect visceral arteries. variations in the brachial artery are the most frequently reported and so far a minimum of six different patterns have been described. the most common of these patterns is the superficial brachial artery, which lies superficially to the median nerve. much less ...

Radial forearm free flaps are commonly used for soft-tissue reconstruction after resection of head and neck cancer. It is perfused by the radial artery, leaving the ulnar artery for perfusion of the hand and digits. The absence of distal ulnar artery and associated superficial palmar arch, however, has not been reported in cadaveric dissection. We report a case of unilateral ulnar artery flow a...
