Although the effect of HLA matching on improving posttransplant survival is controversial in racially mixed populations, most agree that preexisting donor-specific HLA antibodies (Abs) significantly predispose to hyperacute
or acute antibody-mediated allograft rejection (AMR), particularly if the cross-match is positive.
[14-17] Localising signs of hyperacute
infarct or normal NECT brain with significant localising clinical history helps in defining of the area of coverage.
Of the 47 "complicated" type B-AD cases, 13 patients were selected to receive TEVAR with the assisted IVUS evaluation before and after stent implantation, including hyperacute
(2/13), acute (1/13), subacute (4/13), and chronic (6/13) AD, respectively.
CONTROVERSIAL plans to concentrate vital 'hyperacute
' stroke treatment services at a single County Durham hospital will be discussed at a public meeting next month.
A retrospective study of stroke patients in eight centers found that hyperacute
stroke treatment can be initiated, often within 55 minutes of patient's arrival at the hospital in both community and academic settings when all aspects of stroke care processes are identified, streamlined, and built into the day-to-day operations of the hospital healthcare delivery system (Anonymous, 1997).
Finally, that inhibition of caspases might induce hyperacute
TNF-induced shock in certain situations has been recently reported (40).
Exaggerated intravascular contrast enhancement reflecting relative stasis of contrast material within blood vessels in the involved ischemic territory is an MR sign of an acute vascular occlusion.(8) While this sign can be seen within minutes of an occlusion, as it can persist for up to a week and does not identify the specific blood vessel involved, it is therefore relatively nonspecific for identifying a hyperacute
area of ischemic change.
The authors identified five biologic hurdles: hyperacute
rejection, acute vascular rejection, accommodation, cellular rejection, and chronic rejection.
Due to the immaturity of the babies' immune systems, the researchers said none experienced hyperacute
rejection, and no morbidity was attributable to ABO incompatibility.
But since the last few years, there has been increasing evidence indicating the ability of new MRI sequences in detecting not only hyperacute
ischaemic strokes but also haemorrhagic strokes and haemorrhagic transformations.
services are a critical component of stroke care.
The spinal cord-injured patient is at increased risk for ulcers due to the frequent use of NSAIDs for pain, corticosteroids used in acute SCI treatment protocols, anticoagulants used to prevent DVTs, and aspirin used in the treatment of vertebral artery injuries and hypovolemic shock in the hyperacute
phase of the injury (Barton & Vaziri, 2003).
