Percutaneous entry of the brachial artery using a sheath system has been attempted in 223 patients undergoing left heart catheterization; successfully, in 212. After arterial puncture, a dilator and sheath are passed over a short guidewire. A number 7-80 cm Sones specially stiffened coronary catheter is passed through the sheath, and left heart(More)
Left heart catheterization via percutaneous entry of the brachial artery was attempted in 1,783 cases. A plain sheath without valve or side-port was employed and 7 and 8 French Sones catheters were used for females and males, respectively. Successful performance of the procedure was achieved in 96.5% of the cases. Brachial artery occlusion occurred in 1.3%(More)
The mechanisms underlying magnesium (Mg) uptake by plant roots remain to be fully elucidated. In particular, there is little information about the effects of Mg deficiency on Mg uptake activity. A Mg uptake kinetic study is essential for better understanding the Mg uptake system. We performed a Mg uptake tracer experiment in rice plants using 28 Mg. Mg(More)
Angioplasty is most commonly performed with catheters introduced percutaneously into the femoral artery. A brachial approach has previously been described that employs arteriotomy and cutdown. We describe here the technique and initial results of an alternative method of brachial entry, wherein the catheter is introduced percutaneously. Angioplasty has been(More)
