BACKGROUND The relationship between the degree of expression of matrix metalloproteinases or tissue inhibitor of metalloproteinases and venous reflux remains to be investigated. MATERIALS AND METHODS Primary varicose vein tissues were obtained from 23 patients, 18 females and 5 males, aged from 19 to 73. Cephalic or basilic veins were obtained for the control group from 10 patients who underw...

PURPOSE The superiority of autogenous vein conduits is well known in lower extremity arterial bypass (LEAB). Among various alternative conduits for LEAB, long-term results of arm vein grafts were investigated in this study. MATERIALS AND METHODS We retrospectively reviewed clinical characteristics of 28 patients who underwent infrainguinal LEAB with autogenous arm vein grafts at a single inst...

The ameliorative effect of antiplatelet therapy on atherogenesis of vein grafts was assessed in autologous cephalic veins grafted into femoral arteries of 16 normolipemic and 11 hyperlipemic stump-tailed macaque monkeys. Before grafting, one half of each vein was distended at high pressure (700 mm Hg) and the other half at low pressure (350 mm Hg). Eight normolipemic monkeys were treated with a...

The purpose of this study was to report variations of the cubital superficial vein patterns in the Korean subjects, which was investigated by using venous illuminator, AccuVein. The 200 Korean subjects were randomly chosen from the patients and staff of the Keimyung University Dongsan Medical Center in Daegu, Korea. After excluding the inappropriate cases for detecting venous pattern, we collec...

Variations of the gonadal vein involve especial interest in general, vascular, and renal transplant surgery [1]. The testicular drainage originates at the upper pole of the testis, through the pampiniform plexus, which travels alongside the spermatic cord. The origin of the testicular vein, on both sides, lies at the deep inguinal ring, following a cephalic retroperitoneal path along the Psoas ...

The subclavian vein has been used to implant permanent pacing catheters in 40 patients with symptomatic heart block. Though the cephalic and external jugular veins are usually preferred for this purpose in Britain, the use of these veins has certain disadvantages. In this study subclavian venepuncture by the infraclavicular approach was performed without diffculty and found to be a safe procedu...

A bovine shunt, inserted between the radial artery and cephalic vein in the upper arm for access during chronic haemodialysis, caused a distal, ischaemic neuropathy in two patients. There were electrophysiological signs of axonal degeneration of motor and sensory nerve fibres in the patient with severe ischaemia, and, of only sensory fibres in the patient with mild ischaemia. Thenar muscle bloo...

A forequarter amputation is a radical ablative surgical procedure that includes the entire upper extremity with its shoulder girdle. We present a 53-year-old woman with a solid slow growing tumor in her right shoulder of 15 x 20 cm in diameter. Resection and immediate reconstruction with a free radial forearm flap extended from the distal third of the arm to the midpalmar region, taking the hum...
