常见问题

What is the lobar artery of the spleen?
The lobar artery of the spleen is a terminal branch of the splenic artery that arises at the splenic hilum and supplies one of the lobes of the spleen. It is part of the segmental arterial supply of the spleen.
Where is the lobar artery of the spleen located?
The lobar artery of the spleen originates at the splenic hilum, where the splenic artery divides into one or two terminal branches. These branches enter the splenic parenchyma to supply distinct lobar segments.
What is the function of the lobar artery of the spleen?
The lobar artery of the spleen delivers oxygenated blood to a distinct lobe of the splenic parenchyma, supporting the immunological and filtering functions of that splenic segment.
What conditions may be associated with the lobar artery of the spleen?
The lobar artery of the spleen may be involved in splenic infarction when occluded, as the spleen has limited collateral circulation within its lobar segments. Splenic artery aneurysms may also extend to affect the lobar branches at the hilum.
What does the lobar artery of the spleen look like?
The lobar artery of the spleen is a medium-sized arterial branch visible at the splenic hilum on CT angiography or splenic arteriography, typically appearing as one of one to two main terminal divisions of the splenic artery entering the splenic parenchyma.
