Comparative analysis of lower extremities tissue perfusion by the use of perfusion scintigraphy method after hyperbaric oxygenation and lumbar sympathectomy [PDF]

Vojnosanitetski Pregled, 2009
Background/Aim. Lumbar syphatectomy (LS) increases pheripheral blood flow primarily by the arteriolar vasodilatation within the skin vascular net. Increase in tissue nutrition takes place only in the distal blood vessels of the skin.

Liquid Metal Microrobots for Magnetically Guided Transvascular Navigation

Advanced Materials, EarlyView.
Liquid metal‐based microrobots combine magnetic steering, intrinsic X‐ray visibility and softness, to navigate blood vessels even against flow. Under clinically relevant magnetic fields, liquid metal microrobots roll along vessel walls, cross endothelial barriers, and accumulate in target tissues.
