Abstract

Acute spinal cord injury (SCI) is associated with a marked propensity to thromboembolism and a variety of coagulation abnormalities. However, data on blood coagulation profiles in patients with uncomplicated long-standing SCI are limited. These data were studied here. Eight men with uncomplicated chronic SCI and nine able-bodied normal men were studied. Plasma activities and/or antigen concentrations of high molecular weight kininogen (HMWK) and of factors XII, XI, IX, VIII, VII, X, V, II and XIII as well as von Willebrand factor (vWF), fibrinogen and fibronectin were measured by appropriate functional and or immunological assays. The SCI group exhibited normal values for factors XII, IX, VIII, vWF, VII, X and V as well as HMWK, vWF and fibronectin concentration. However, they showed slight reductions in plasma factor XI activity, factor XIII antigen concentration and modest increases in fibrinogen and factor II concentrations. No correlation was found between the parameters studied and either the duration or the level of injury. In conclusion, in contrast to acute SCI, the coagulation profile in uncomplicated chronic SCI is noted to be largely normal with only a few minor alterations of questionable clinical significance.
