RESUMO
@#Objective To investigate the efficacy and safety of radiofrequency thermocoagulation guided by spiral CT on severe trigeminal neuralgia in the oldest old patients. Methods 21 patients above 80 with severe idiopathic trigeminal neuralgia were treated with radiofrequency thermocoagulation guided by spiral CT. They were assessed with numeric rating scales (NRS) and the complication were observed. Results The scores of NRS decreased significantly after treatment (P<0.01). No serious complication was observed after treatment. One patient recurred 23 months after operation, and the pain released after radiofrequency thermocoagulation once again. Conclusion Radiofrequency thermocoagulation guided by spiral CT is effective and safe for severe trigeminal neuralgia in the oldest old patients.
RESUMO
Objective To evaluate blood-brain barrier around the hematoma in patients harin g hypertensive cerebral hemorrhage. Methods Tissues from blood-brain barrier around t he hematoma were collected, and at the same time to cerebeal hemorrha gic patients the hematoma extracting. Results Within asuper early peroid (7 hours) and acute peroid (72 hours) a nd subacute peroid (4～7 days) of the cerebral hemorrhage, the tissues of blood-brain barrier observed under electronic micrscop e, showed that the damagement of the blood-brain barrier was increas ed in direct proprotion to the length of time and the patients presenting a relevant clinical manifestation mean-while.Conclusion The changes of blood-brain berrier is more importment for a t imely treatment, and a hemotoma extracting is suggested as to improving the live qua lity of patients.
