Váh

(väkh), Hung. Vág, river, c.245 mi (390 km) long, Slovakia. It is formed by the union of the Biély Váh, rising in the High Tatra, and the Cierny Váh, rising in the Low Tatra, and flows SW into the Danube at Komárno. The Orava and Nitra rivers are its chief tributaries.

Váh

 

a river in Czechoslovakia (in Slovakia). Left tributary of the Danube.

The Váh River is 433 km long; the area of its basin is 19,600 sq km. It is formed by the confluence of the Biely Ván and the Cierny Váh Rivers, which have their sources in the High Tatra and Low Tatra mountains. The greater part of the Váh flows through the hills, below the city of Nové Mesto and out onto the Central Danubian Lowland. There are floods during summer. The average discharge of water is 152 eu m per sec.

The Váh is used for water supply, irrigation, and energy. Built on the Váh and its tributary the Orava is the Váh Cascade—a system of 20 hydroelectric power stations (with an average capacity of 20,000-50,000 kW), most of which have already been put into operation. These hydroelectric power stations operate on derivation canals that run along the riverbed. The Váh is navigable as far as the populated area of Sered. The river is also used for floating logs. Cities located along the Váh include Ružomberok, Žilina, and Trenčin.

Based on VISTA images, acquired atherosclerotic stenosis was distinguished from VAH firstly when wall thickening (with or without thrombus) was found in the suspicious VAH, and outer vessel diameter was more than 50% of the dominant vertebral artery.
The clinical and wall characteristics were compared between the VAH patients with atherosclerosis and VAH patients with normal wall [Table 1].
Between June 2014 and February 2015, a total of 30 patients (male: 26; female: 4) with suspicious intracranial VAH were enrolled.
Five of the 30 patients with possible unilateral intracranial VAH suggested by luminograms were finally diagnosed as acquired atheroslcerotic stenosis due to the presence of atherosclerotic plaque with similar vessel outer diameter as the dominant verterbral arteries on the HR MRI.
Of the 25 VAH patients, HR MRI showed normal wall in 9 patients [Figure 2] and atherosclerosis in 16 patients including little atherosclerotic plaque in 9 patients [Figure 3], slight wall thickening in 6 patients [Figure 4], and thrombus and wall thickening in 1 patient [Figure 5].
Compared with the VAH patients with normal wall, VAH patients with atherosclerosis showed atherosclerotic basilar arteries and dominant vertebral arteries more frequently ( P = 0.
