ABSTRACT
Objective To evaluate the effect of blocking the posterior branc h of lumbar nerves in treatment of the lower lumbago and scelalgia caused by the i njury of the posterior branch of lumbar nerves. Methods 560 cases with lower lum bago and scelagia caused by the injury of the posterior branch of lumbar nerves were randomized into the treating group and the contrast group. Follow-ups were done 2 to 3 months after the treatment. Then the effects of the treatment were evaluated. Results The effective rate of the treating group was 98. 0 %,and th e excellect and good rate was 83.0 %; the effective rate of the contrast group was 83.3 %,and the excellect and good rate was 64.9 %. The differences in tre atment effects between the two groups are statistically significnt (P
ABSTRACT
Objective To investigate the features of digital subtraction angiography(DSA) of meningioma and the application of therapy in preoperative embolization.Methods DSA in 36 cases with meningioma proved pathologically was performed.Of them,22 cases which the blood supply of tumor was mostly by external carotid artery were undergone external carotid artery embolization and surgical incision 3~10 days after embolization.Results Among 36 cases,the blood supply of tumor was only from external carotid artery in 9 cases,both of external and internal carotid artery supply in 25,and only internal carotid artery in 2.Among 22 cases undergone embolization of supplying artery the tumor stain absolutely disappeared in 16,evidently decreased in 6.22 cases undergone surgical incision after embolization,the tumors were wholly resected,average bleeding 150~500 ml during surgery.Conclusion The blood supply of meningioma can be only by external or internal carotid artery,or both.Preoperative cerebral angiographies and embolization are beneficial for the total resection of meningioma and reduction of bleeding during surery.
ABSTRACT
36 patients with cancer of rectum treated by infusion chemotherapy after selective inferior mesenteric arteriography were reported.All patients had good result.A- mong them 13 cases without embolization,showed vascular blockage,decrease in size of tu- mor on follow up angiographies and reduction of bleeding during operation.The authors be- lieved that arterial infusion chemotherapy not only can kill tumor cells hut also resulted in degenerative change of vascular endothelia,necrosis and vascular occlusion.Simultaneously it can also stimulate the tissue in the periphery of tumor to produce inflammatory cell infil- tration and fihroplasia,suppress the grwoth of tumor,prevent the spread of tumor cells and metastasis;thus prolong the survival time.Interventional treatment is of great value to can- cer of rectum.The indications were recommended.
