Hereditary angioedema: report of a family in Malaysia.

The most likely cause for PDPH is leakage of cerebrospinal fluid from a hole in the dura, the remarkable feature being that such a trivial injury can cause such severe symptoms. Conservative management with bed rest, analgesics and fluids is helpful in those with mild symptoms. Relief however, is not dramatic and sealing that hole in the dura is the only way to achieve rapid relief Gromley (1960)1 was the first to report on the use of autologous blood into. the epidural space to "patch" the hole and there have been many reports of success with this technique with some authors even advocating its prophylactic use2 . We would like to share our local experience with this method of relief of "spinal headache".
