颈椎管哑铃形肿瘤的显微外科治疗   总被引:2,自引:1,他引:1  
目的探讨不同入路显微手术切除颈椎管哑铃形肿瘤的手术方法,总结其主要优点和术后并发症情况。方法2004年5月至2006年7月共收治16例颈椎管哑铃形肿瘤,其中5例肿瘤最大径超过5cm。5例巨大肿瘤中4例位于上颈段,采用侧方改良的极外侧入路(后外侧肌间入路), 1例外院手术复发的巨大肿瘤位于中颈段,采用分次后正中和前路联合切除并行后方和前方内固定加前方植骨融合;1例肿瘤椎管外部分向前方生长,采用颈前入路切除后行前方植骨融合加内固定,其余10例采用后正中入路,其中1例超过中线的肿瘤采用全椎板切除加椎管成形,7例半椎板切除, 1例复发肿瘤原路切除,1例未切除椎板切除肿瘤。结果手术全切肿瘤14例,次全切2例。所有病例术后症状均有明显改善,其中2例巨大肿瘤患者术后出现低氧血症,重新气管插管后逐渐恢复, 1例巨大肿瘤患者术后脑脊液漏皮下积液,经穿刺置管引流数日后恢复正常。其中12例随访9-18个月,无一例复发或出现脊柱不稳定的情况。结论对于颈椎管哑铃形肿瘤,应尽可能采用创伤小的手术方式,在切除肿瘤的同时,减少棘突、韧带、椎板以及小关节的破坏,减小创伤和对脊柱稳定性的破坏,预防脊柱后凸和侧凸畸形的发生。极外侧入路适用于微创切除体积较大的高颈段椎管哑铃形肿瘤,较小的肿瘤可以采用后正中入路半椎板开窗手术,对骨质破坏严重者需在切除肿瘤后行内固定手术。  相似文献

子宫内膜息肉中雌、孕激素受体的表达   总被引:2,自引:0,他引:2  
目的检测子宫内膜息肉雌激素受体(ER)、孕激素受体(PR)的表达,探索子宫内膜息肉形成的原因及机制。方法子宫内膜息肉48例为观察组,正常子宫内膜36例为对照组,采用免疫组化SP法,行半定量分析,检测ER、PR的表达。结果增殖期的息肉组织中PR表达的评分结果为(2.89±2.16),低于增殖内膜的评分(4.04±1.73),差异有统计学意义(P<0.05);分泌期的内膜息肉中ER表达的评分结果为(3.80±1.64),高于分泌期内膜中的评分(2.64±1.45),差异有统计学意义(P<0.05)。结论增殖期的子宫内膜息肉中PR的表达降低及分泌期的息肉中ER表达增高可能参与了子宫内膜息肉的形成及发展。  相似文献

The level of blood lipid of patients in two groups was measured with American Beckman automatic biochemistry analyzer. Blood flow rate of middle cerebral artery of resting electrocardiogram were measured with American HP SONOS 2500 sonoscope. Neuro-dysfunction score revised in the national conference (1995) was used to evaluate the recovery of neurological function of the patients in two groups at the 3rd, 5th, 7th and 14th days after therapy. ③Therapeutic effect and adverse effect were observed at the same time.MAIN OUTCOME MEASURES: ① Changes of coagulation index, blood lipid level and hemorheology; ② Blood flow rate of middle cerebral artery and NDS of patients with acute ischemic stroke in two groups; ③Adverse effect of drug.RESULTS: Totally 90 patients were enrolled in the experiment. One patient from treated group died of hyperosmolar nonketotic diabetic coma of complicated diabetes mellitus. One patient from control group died of severe pulmonary infection. The rest 88 patients entered the stage of result analysis. ① Change of coagulation index and platelet aggregation rate: prothrombin time (PT), activated partial thromboplastin time (APTT) and thrombin time (TT) of patients after therapy were significantly longer than those before therapy in the treated group and those after therapy in control group [After therapy in treated group: (18.4±1.9),(41.8±2.1), (19.7±1.7)s, Before therapy in treated group: (13.4±1.3), (35.8±1.3), (12.5±0.9)s, After therapy in control group: (16.9±1.5), (39.1±1.1), (11.9±2.1) s, P < 0.05] ;Concentration of fibrinogen (Fbg) after therapy was significantly lower than that before therapy in the treated group and that after therapy in control group[After therapy in treated group: (3.4±0.4) g/L; Before therapy in treated group: (4.3±0.7) g/L;After therapy in control group:(4.0±0.6) g/L; P < 0.05]. Platelet aggregation rate decreased from (37.92±0.85)% before therapy to (26.42±1.01)% after therapy (P < 0.01). ②Change of blood lipid level: Levels of total cholesterol (TC), triacylglycerol(TG) and Iow density lipoprotein cholesterol (LDL-C) of patients after therapy were significantly lower than those before therapy in treated group and those after therapy in control group [After therapy in treated group: (5.2±0.9), (1.9±0.9), (2.08±1.1) mmol/L, before therapy in treated group:(5.9±1.2), (2.8±0.9), (3.94±0.5) mmol/L, After therapy in control group: (6.0±1.1), (2.6±0.8), (3.84±0.9) mmol/L,P < 0.05]. ③ Change of hemorheology index: Hematocrit of patients of treated group was significantly lower after therapy than before therapy [Before therapy: (43.84±4.55)% ;After therapy: (40.48±4.02)% ;P < 0.05].④ Blood flow rate of middle cerebral artery of patients of treated group was significantly lower before therapy than after therapy [(90±1.2), (97±2.1) cm/s,P < 0.01]. ⑤ NDS of patients in treated group was significantly lower than of control group 14 days after therapy. The total effective rate after therapy was significantly higher in the treated group than in the control group (93%,78%, P < 0.05). ⑥There was no obvious adverse effect.CONCLUSION: Modified hemodilution combined therapy can improve hemorheology, decrease hematocrit,increase blood flow rate of middle cerebral artery, so as to improve the impaired clinical neurological function of elderly patients with acute cerebral thrombosis through anticoagulation and antiplatelet aggregative activity as well as regulating blood lipid.  相似文献
