Abstract
A postsurgical pseudomeningocoele (PSPM) forms when cerebrospinal fluid extravasates through a dura-arach-noidal tear and becomes encysted within the wound. Patients may become symptomatic with wound swelling, headache and radiculopathy. A uniform method of repairing PSPMs is described which includes separation of the dura from the arachnoid, dural repair under operating microscope control, and the use of overlapped local flaps to reinforce the dura and obliterate the PSPM sac. Four recent cases are presented which were successfully treated using this method.
