These four techniques are (a) fluoroscopy, (b) ultrasound, (c) micropuncture
access, and (d) femoral angiography .
Next, with the patient in the prone position, venous access was achieved with a 4F micropuncture
needle set through the ipsilateral small saphenous vein.
In group I patients, a sterile rolling device with needles of length 1.5 to 2.5mm was rolled across the skin with pressure in multiple directions until the area demonstrates uniform pinpoint bleeding through thousands of micropuncture
(11,12,18,19) Under CT guidance, a catheter was introduced into the posterior para- or perirenal space using a 4-Fr micropuncture
Evidence from the micropuncture
studies of Dworkin et al.
After accessing the right femoral artery with a micropuncture
needle under ultrasound guidance, a thoracic aortogram was performed using a 5Fr pigtail catheter.
studies in rats and functional MRI studies in rats also found tubular fluid viscosity to be much higher following IOCM than LOCM [43, 52].
studies to evaluate renal hemodynamics
We were able to check the correct localisation of the common femoral artery puncture and reduce the risk of retroperitoneal bleeding using micropuncture
sets and contrast injections under fluoroscopy.
needles combined with ultrasound guidance for unusual central venous cannulation: desperate times call for desperate measures: a new trick for old anesthesiologists," Anesthesia and Analgesia, vol.
and cannulation studies of fluid composition and transport in the ductuli efferentes testis of the rat: comparisons with the homologous metanephric proximal tubule.
Venous access is obtained through an unaffected venous segment upstream from the thrombus using a micropuncture
technique under ultrasonographic guidance.
