Review Case Reports
Spinal epidural hematoma during anticoagulant therapy. A case report and review of the literature.
The authors present a case of spinal epidural hematoma during anticoagulant therapy. Clinical presentation is characterized by classic paravertebral back pain, followed by progressive neurological deficit due to spinal cord and radicular compression, with sensory deficits and bladder disturbance. ⋯ Early surgical decompression of the spinal cord minimizes the degree of permanent neurological damage, because of the long-time compression of the spinal cord resulting in irreversible disturbance of circulation; therefore an early diagnosis is a better prognosis. The thoracic and cervical spine canal is smaller than the lumbar, therefore there is less space to reward the formation of hematomas, consequently the postoperative recovery is lower in patient with high spinal epidural hematomas with respect to lumbo-sacral spinal epidural hematomas; at this level the epidural hematoma may be insidious in its onset and tends to become chronic before definite treatment is undertaken.

Percutaneous retrogasserian glycerol rhizolysis (PRGR) became a diffuse and valuable method for treatment of trigeminal neuralgia, following its introduction by Hakanson in 1981. Its main advantages are: a) mild postoperative facial sensory loss, b) simplification of the technique, c) reduction of costs. Our results in a series of 191 patients treated between September 1983 and September 1990 are reported. ⋯ The mean time of recurrence was 30.5 months. The recurrence rate in the patients of our series at the end of the follow-up period was 23%. Glycerol produces a weak neurolytic lesion, that generates minor post-operative facial deafferentation; it is the best technique, in our opinion, for treatment of tic douloreux.
