segmental arteries of kidney

(redirected from Segmental arteries)

seg·men·tal ar·ter·ies of kid·ney

[TA]
the branches of the renal artery that supply the anatomic segments of kidney. Usually five in number, they are end arteries and give off interlobar, arcuate, and interlobular arteries in sequence. The latter send afferent arterioles to the glomeruli as well as branches to the kidney capsule. The segmental arteries of the kidney are identified as: 1) anterior inferior (arteriae segmenti anterioris inferioris renalis [TA]); 2) anterior superior (arteriae segmenti anterioris superioris renalis [TA]); 3) inferior (arteriae segmenti inferioris renalis [TA]); 4) posterior (arteriae segmenti posterioris renalis [TA]); and 5) superior (arteriae segmenti superioris renalis [TA]).

Segmental arteries are usually end arteries and collaterals can occur between segments.
The splanchnic arteries arise at an early stage of fetal development (fourth week) as paired ventral segmental arteries from the paired dorsal aorta to supply the yolk sac.
The arterial supply to each vertebral body consists of paired segmental arteries that arise, depending on the location, from the vertebral arteries, the aorta, or the iliac arteries.
Pulmonary artery thrombi in both principal arteries before bifurcation, with extension on lobar arteries and some of segmental arteries were documented (Figures 3a and 3b).
Advanced contemporary techniques like partial left heart bypass, deliberate hypothermia, DHCA, reattachment of segmental arteries, lumbar CSF drainage, arterial pressure augmentation, and intraoperative neurophysiologic monitoring have improved the safety of thoracic and thoracoabdominal aortic aneurysm repair5,6.
It has been reported that, in the setting of renal artery thrombosis, there may be a great variability in laboratory values depending on the number and size of segmental arteries affected, the intensity of ischemic injury, the time of development, and the presence of collateral circulation.
The blood supplying arteries for lumbar vertebra, normally called segmental arteries, are originated from the abdominal aorta.
The right coronary artery (RCA) arose normally from the right coronary sinus and had a normal posterior descending artery (PDA) and several long posterolateral segmental arteries.
The spiral CT criterion used to diagnose PE consisted of direct visualization of non-occlusive endoluminal thrombus (central filling defect or partially outlined by contrast agent) or of complete occlusion by thrombus in normal sized or enlarged vessels including the main pulmonary arteries, lobar arteries, segmental arteries and sub-segmental vessels.
Near the hilum each artery divides into anterior and posterior division, which in turn divides into segmental arteries supplying renal vascular segments.
