Experimental Cholelitholysis with the Pulsed Tunable Dye Laser Open
This study evaluates the pulsed tunable dye laser with wavelength 504 nm, frequency 10 Hz, and pulse width 1.2 microseconds for cholelitholysis. Power of 10-40 kW was directed through a 250-microns quartz fiber optic to ablate 55 gallstone…

Initial clinical evaluation of carotid artery laser endarterectomy Open
Clinical study of carotid artery laser endarterectomy began April 15, 1988. This report describes the first 10 cases that were performed in nine patients (five men and four women, mean age 70 years). Indications were asymptomatic stenosis …

A Systematic Appraisal of Portacaval H-Graft Diameters Open
Over a period of 10 years, the authors have systematically reduced portacaval H-graft diameters. Their objective was to achieve partial shunting of portal flow without reversal of hepatic flow. This report summarizes their clinical and hem…

Predictability and Maintenance of Portal Flow Patterns After Small-Diameter Portacaval H-Grafts in Man Open
Patients undergoing small-diameter (8, 10, 12, and 14 mm) portacaval H-grafts were followed up to 3.5 years. Eight- and 10-mm grafts maintained prograde portal perfusion in 50% of the patients. Follow-up studies performed from 6 to 36 mont…

Portacaval H-Graft Open
Small-diameter protacaval H-grafts, 10, 12, or 14 mm, were constructed in 29 cirrhotic patients with previous or active variceal hemorrhage. When 10 mm grafts were used in combination with portal collateral outflow ligation, varying degree…
