in order to create an effective arteriovenous fistula (avf) in patients with sustained chronic renal failure (crf), surgeons need to become familiar with various anatomical variations of venous structures in the operating field. because of variety and different types of cubital venous anatomies, there is more than a 90% possibility of creating suitable avfs in the cubital fossa , but in the wri...

The brachial artery begins as a continuation of the axillary artery and is superficial throughout its course in the arm. When it enters the cubital fossa it lies anterior to the brachialis muscle and lateral to the median nerve. In cubital fossa it lies deep to bicipital aponeurosis which separates the artery from median cubital vein. The median nerve descends along the lateral side of the prox...

Brachialis muscle lies beneath the biceps brachii and arises from anteromedial and anterolateral surfaces of the lower half of the shaft of humerus. A few fibers take origin from lower part of spiral groove and medial intermuscular septum also. The broad muscle covers the anterior part of elbow joint and converges to form a flat tendon which is inserted into the anterior surface of coronoid pro...

Radial artery is one of the terminal branches of the brachial artery arising in the cubital fossa; the other being the ulnar artery. Radial artery usually begins in the cubital fossa about 1 cm below the bend of the elbow at the level of the neck of the radius just medial to the tendon of biceps brachii muscle, and terminates in the hand by forming the deep palmar arch after anastomosing with t...

Ultrasonography is the primary tool for preoperative analysis of vein morphology for fistula creation in patients with end-stage renal disease. This study examines the effect of environmental temperature on the superficial vein size. Superficial veins of thirteen healthy volunteers were marked at three sites: cephalic vein in left lateral arm near cubital fossa, cephalic vein in left forearm at...

CASEREPORT. A previously healthy twenty-six year old woman presented to casualty about one hour after self injection with metallic mercury using her boyfriend's insulin syringe. The mercury had been taken from an old thermometer in an attempt at suicide following an argument. She smoked 20 cigarettes a day; there was no previous medical history. On examination there was some localised inflammat...

Patterns of superficial veins of the cubital fossa were studied in 170 male and 96 female Malays. Six venous patterns were observed. The less commonly known but clinically important patterns observed included absence of communication between basilic and cephalic veins (in 7.3% females and 8.8% males); an arched median cubital vein (in 2.0% females and 6.5% males); absence of the cephalic vein (...

conclusions although the results of this study showed superiority of application of emla cream as a topical anesthetic for pain relief of blood sampling, both lidocaine 5% and benzocaine 5% offer considerable efficacy in pain relief of venipuncture. results at the end of study, the emla products (a and b) caused a significant decrease in pain (p < 0.05) in comparison with the products c (lidoca...

OBJECTIVE To compare the performance on the detection of the invisible veins between our modified prototype device and an existing device in elderly hospitalized patients. METHODS A prospective, cross-sectional, and observational study was performed in the invisible veins in elderly patients. The major variables, skin color near the invisible veins, and diameter and depth of the invisible vei...

BACKGROUND Ulnar nerve entrapment (UNE) has been diagnosed with clinical examination and electrodiagnostic studies. This study was designed to determine the value of a combination of grey-scale and color Doppler ultrasound findings in the diagnosis of patients with UNE. MATERIALS AND METHODS During May to August 2013 41 patients with UNE (proven by electrodiagnostic studies) and 44 healthy vo...
