The transradial approach for catheterization is becoming increasingly more popular. At present, the choice of the right or left radial artery depends on the operator's preference. We examined how the laterality influenced the effectiveness of the approach. Employing Judkins-type catheters, we performed coronary angiography in 232 patients with the left(More)
When 7,12-dimethylbenz[a]anthracene-impregnated sutures were directly applied to the ovarian parenchyma of 8-week-old Sprague-Dawley rats (the clipping method), adenocarcinomas developed in 29 (39%) of the 75 rats during the 50-week observation period. When 20-methylcholanthrene was used, adenocarcinomas developed only in 1 (3%) of the 31 rats. Thus, the(More)
The radial artery approach is becoming more popular for diagnostic cardiac catheterization and interventional procedures because of its lower incidence of access site complications and decreased patient discomfort after the procedure. However, Allen's test reveals inadequate blood supply through the ulnar artery to the hand, and therefore the approach does(More)
We examined the response of the radial artery to vasoactive agents (isosorbide dinitrate, ISDN, 1 mg, 3 mg, and 5 mg; verapamil, 1 mg, 3 mg, and 5 mg; and lidocaine, 10 mg, 30 mg, and 50 mg) in 100 consecutive patients admitted for elective coronary angiography. The drug solutions were directly injected into the radial artery from the puncture site. As a(More)
The percutaneous arm approach through the radial or brachial artery for diagnostic cardiac catheterization has advantages, such as a lower incidence of access-site complications and decreased patient discomfort, particularly when smaller diameter catheters are employed. However, the pressure produced by high-flow jets of contrast material exiting from an(More)
The recurrence of the patients who had obtained remissions once was studied and the standard of remission was reassessed. The comparison of the titers of hCG ranged the LH levels was studied by means of some methods of measurement. 1) During 7 years, from 1973-1979, 141 patients with trophoblastic disease in Chiba University Hospital were treated. The(More)
For patients for whom the conventional percutaneous transluminal coronary angioplasty (PTCA) did not adequately improve stenosis, or sufficient angioplasty was impossible because of occurrence of dissection, we attempted using a long-time balloon inflation for more than 10 minutes. In order to allow the use of this balloon, we instituted an active(More)
A 57 years old woman was admitted for the investigation of anginal chest pain. Her coronary angiography didn't show any typical finding seen in the aortitis syndrome, but coronary sclerosis and stenosis seen in the usual atherosclerotic patients. The cerebral angiography was performed, too. The right vertebral artery, which was tortuous and dilated, was(More)
