Ultrasonic flow detection for localization of splenic and renal veins. 1976

W C Johnson

The selective splenorenal shunt is currently recommended as an alternative procedure to portocaval shunting. However, this operation is technically more difficult, particularly the localization of the renal vein in patients with thickened retroperitoneal tissues. The Doppler flow detector has helped us identify the splenic and renal veins, and we suggest the intraoperative use of this instrument in situations where difficulty is encountered.

UI	MeSH Term	Description	Entries
D012082	Renal Veins	Short thick veins which return blood from the kidneys to the vena cava.	Renal Vein,Vein, Renal,Veins, Renal
D004301	Doppler Effect	Changes in the observed frequency of waves (as sound, light, or radio waves) due to the relative motion of source and observer. The effect was named for the 19th century Austrian physicist Johann Christian Doppler.	Doppler Shift,Effect, Doppler,Shift, Doppler
D004932	Esophageal and Gastric Varices	Dilated blood vessels in the ESOPHAGUS or GASTRIC FUNDUS that shunt blood from the portal circulation (PORTAL SYSTEM) to the systemic venous circulation. Often they are observed in individuals with portal hypertension (HYPERTENSION, PORTAL).

D006801	Humans	Members of the species Homo sapiens.	Homo sapiens,Man (Taxonomy),Human,Man, Modern,Modern Man
D013162	Splenic Vein	Vein formed by the union (at the hilus of the spleen) of several small veins from the stomach, pancreas, spleen and mesentery.	Splenic Veins,Vein, Splenic,Veins, Splenic
D014463	Ultrasonography	The visualization of deep structures of the body by recording the reflections or echoes of ultrasonic pulses directed into the tissues. Use of ultrasound for imaging or diagnostic purposes employs frequencies ranging from 1.6 to 10 megahertz.

D014465	Ultrasonics	A subfield of acoustics dealing in the radio frequency range higher than acoustic SOUND waves (approximately above 20 kilohertz). Ultrasonic radiation is used therapeutically (DIATHERMY and ULTRASONIC THERAPY) to generate HEAT and to selectively destroy tissues. It is also used in diagnostics, for example, ULTRASONOGRAPHY; ECHOENCEPHALOGRAPHY; and ECHOCARDIOGRAPHY, to visually display echoes received from irradiated tissues.	Ultrasonic
