Vanilloid type 1 (VR-1) receptors are stimulated by capsaicin and hydrogen ions, the latter being a by-product of muscular contraction. We tested the hypothesis that activation of VR-1 receptors during static contraction contributes to the exercise pressor reflex. We established a dose of iodoresinaferatoxin (IRTX), a VR-1 receptor antagonist, that blocked the pressor response to capsaicin inje...

PURPOSE To describe the popliteal and distal branching patterns detected by digital subtraction angiography. MATERIALS AND METHODS The popliteal branching patterns were analyzed in 535 extremities (270 right, 265 left). Of these, 226 limbs were evaluated bilaterally, while 83 were evaluated unilaterally. The branching patterns were classified according to the level of branching and the presen...

BACKGROUND To investigate the usefulness of popliteal artery spectral doppler findings as a complimentary approach to isolated calf vein thrombosis (DVT). MATERIAL/METHODS We included consecutive patients presenting with symptomatic and sonographically proven acute isolated calf DVT. Patients with thrombosis of any other vein were excluded. We classified calf vein into into four main types. W...

SUCH rapid advance has occurred over the past few years in the surgical treatment of disease of large arteries that this work is no longer experimental and is now soundly established. The majority of cases are due to arterio-sclerosis which involves certain segments of the vascular tree, leaving the remainder relatively free from disease. The most frequently involved segments are: 1. Superficia...

In normal anatomy, the anterior tibial artery is typically first branch of popliteal before it becomes tibioperoneal trunk. The course includes piercing through interosseus membrane and continuing compartment. It then continues onto dorsum foot as dorsalis pedis at level malleoli. We describe a unique case an anomalous origin from peroneal artery. important for vascular surgeons to be aware thi...

Objective To evaluate the effect of patient characteristics on popliteal aortic contrast enhancement at lower extremity CT angiography (LE-CTA) scanning. Materials and Methods Prior informed consent to participate was obtained from all 158 patients. All were examined using a routine protocol; the scanning parameters were tube voltage 100 kVp, tube current 100 mA to 770 mA (noise index 12), 0....
