Capillary refill time is traditionally used as a clinical indicator of tissue vascularity either after limb injury or after revascularization [15] and the most reliable and applicable site for CRT testing is the finger pulp (not at the fingernail), and the cut-off value for the normal CRT should be 3 seconds, not 2 seconds.

End arteries are of particular interest to medicine where they supply the heart or brain because if the arteries are occluded, the tissue is completely cut off, leading to a myocardial infarction or an ischaemic stroke. Other end arteries supply all or parts of the liver, intestines, fingers, toes, ears, nose, retina, penis, and other organs. [2]
The pressure on the wound constricts the blood vessels manually, helping to stem blood flow. When applying pressure, the type and direction of the wound may have an effect, for instance, a cut lengthways on the hand would be opened up by closing the hand into a fist, whilst a cut across the hand would be sealed by making a fist.
Still elevated, the hand is then opened. It should appear blanched (pallor may be observed at the finger nails). Ulnar pressure is released while radial pressure is maintained, and the colour should return within 5 to 15 seconds. If color returns as described, Allen's test is considered to be normal.
Here, the nerves that signal the blood vessels of the fingertips to constrict are surgically cut. Microvascular surgery of the affected areas is another possible therapy, but this procedure should be considered as a last resort. A more recent treatment for severe Raynaud's is the use of botulinum toxin.
The radialis indicis artery (radial artery of index finger) is a branch of the radial artery that provides blood to the index finger.. It arises close to the princeps pollicis artery, and descends between the first dorsal interosseous muscle and the transverse head of the adductor pollicis, and runs along the lateral side of the index finger to its extremity, where it anastomoses with the ...
In a sneak peek, Kim Kardashian visits a doctor's office where she shows off her bandage-free finger. "Oh, that looks great!" the doctor says as he removes Kim's bandage to reveal her sliced finger.
It is done by tying string or dental floss around the acrochordon to cut off the blood circulation. [7] Home remedies include commercial ligation bands that can be placed around the base of skin tags. [8] Complications of ligation in polydactyly treatment include infection, neuroma or cyst formation. [9]
