The testosterone, FSH and LH plasma levels were determined simultaneously in spermatic and cubital veins in 15 patients with post-inflammatory azoospermia. The testosterone levels in spermatic vein was 13,1 +/- 2,9 times higher than in cubital vein. FSH spermatic plasma level was slightly higher than in cubital vein, whereas LH spermatic plasma level did not differ from that found in the cubital vein.

Department of Cardiovascular, The Second Affiliated Hospital of Chongqing Medical University, No. 74, Linjiang Road, Yuzhong District, Chongqing, 400010, China.
In order to provide some references for vein approach selection in adrenal vein sampling (AVS), this retrospective study analyzed 325 cases of primary aldosteronism (PA) patients who underwent AVS via the upper extremity vein approach, comparing the differences in complications and visual analogue scale (VAS) scores through median cubital vein (MCV), basilic vein (BV), and cephalic vein (CV). The results indicated no significant difference in the incidence of venous spasm (right MCV vs. right BV vs.

Background: Ultrasound guidance is commonly used for accessing difficult peripheral veins. For successful access, a tourniquet is required for venodilation. Tourniquets decrease the compressibility and increase the diameter of veins; they also obfuscate artery-vein differentiation on ultrasound.
