[Color-coded duplex ultrasonography compared to phlebography in deep leg and pelvic vein thrombosis].

Between March 1990 and March 1991, in a prospective study, 100 patients (53 men, 47 women, median age 61.5 years) with suspected deep venous thrombosis of the lower extremities, colour duplex ultrasonography (CDU) (Ultramark 9, ATL) were investigated using the slow-flow technique. The CDU findings obtained for the external iliac vein (distal segment), the common femoral, the superficial femoral and popliteal veins, together with those of the veins of the lower extremity, were compared with the results of phlebography, which is considered to be the gold standard for this type of investigation.

[Ultrasonographic findings in varicose phlebitis of the great saphenous vein. Evidence of thrombus growth and detachment with asymptomatic lung embolism].

In five women (mean age 58 [31-74] years) with clinically diagnosed varicose phlebitis of the long saphenous vein appositional thrombus growth was demonstrated by serial ultrasonography (B-mode compression and colour-coded duplex sonography). In one patient the appositional thrombus was found to be free-floating as far as the common femoral vein, but this was not seen by phlebography. During therapeutic heparinization there was ultrasonographic evidence of softening and partial liquefaction of thrombus material in a cranial direction.

[Unapparent course of pancreatitis with pseudocyst development and cholestatic jaundice in anticonvulsive therapy with valproate].

Valproic acid is a reliable and comparatively safe drug in the treatment of special forms of absence seizures. Severe but very rare complications include acute liver necrosis and acute pancreatitis which may end lethally. A case of a previously unreported association of pancreatic pseudocyst and development of cholestatic icterus in conjunction with valproic acid therapy is presented.

Response of plasma catecholamines and blood pressure to clonidine and to sudden withdrawal of the drug in subjects with essential hypertension.

In this retrospective study in ten patients with essential hypertension a short-time treatment of 3 days with 0.15 mg clonidine 2 times/day orally, as well as a second short-term treatment period with the slow-release oral preparation (.025 mg clonidine once/day) significantly lowered blood pressure, heart rate, and plasma concentration of norepinephrine in the supine and standing subject.
