The article reviews the changes of hematoma and ischemic penumbra, brain edema, hyperfibrinolysis after cerebral hemorrhage, and as well as amyloid angiopathy.
Objective:To evaluate the efficacy of transfer of the first metacarpal flaps with vascular pedicle in treatment of the ischemic necrosis of scaphoid lunatum.
Sheehan's syndrome is typically diagnosed by measuring the pituitary hormones levels - which usually fall depending on the severity of the ischemic necrosis.
Coupled with the increased demand for blood by the lactotrophs, the pituitary cells no longer receive enough oxygen to survive - resulting in ischemic necrosis.
In other words, the lactotrophs are just barely getting enough oxygenated blood, and they will become ischemic and die if blood flow is reduced further.
