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]).

Ultrasound scanning in our study permitted the segmental arteries of the lower limbs to be imaged for stenosis and occlusions, enabling the overall severity of the PAD to be graded using the piecewise integral method based on the degree of arterial stenosis.
There was an embolism close to totality in the bilateral main pulmonary arteries and segmental arteries. Both pulmonary artery diameters were increased (Picture 2).
These segmental arteries does not have collateral system, so when there is any occlusion of these arteries which results in the ischemia of the particular segment of kidney (1).
Despite the excellent quality of vascular opacification in CTPA images, the accuracy of detecting PE in peripheral segmental arteries may be limited owing to inadequate visualization of oblique vessels in the plane of the CT sections 8.
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.
Acute renal infarction appears as the absence of perfusion on color- and power-Doppler examination, complete when the entire kidney is affected or patchy when segmental arteries are involved.
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.
