Objective To analyze the central visual fields and the ocular fundus changes of both eyes of patients with pituitary adenoma.Methods A total of 70 cases of pituitary adenoma received the examination of static central visual fields of all-liminal values by Humphrey instruments 750 cycloscope and the fundus exams by Topcon TRC-50X fundus photography before operations. Results There were 64.3% patients with decreased visual acuities, 80.7% with the defect of visual field, and 46 .4% with fundus changes. The decrease of the visual acuity was the first diagnostic symptom in 45.7% patients, among whom 28.6% were misdiagnosed as ocular diseases.Conclusions The misdiagnosed cause is that the first diagnostic symptom is the decrease of visual acuity without defect of visual field accompanied by ocular diseases. To avoid the misdiagnosis and the omitter of pituitary adenoma, general examination of visual field should be carried out in the patients with decreased visual acuity and optic atrophy with unknown reason in the clinical diagnosis of ophthalmology.

【摘要】 目的 探讨伽玛刀治疗垂体腺瘤远期肿瘤控制及并发症发生情况。 方法 2004年6月-2006年12月共158例垂体腺瘤患者接受伽玛刀治疗。伽玛刀治疗边缘剂量12～30 Gy，以45%~70%等剂量曲线覆盖肿瘤灶。术后定期对患者进行门诊随访和鞍区增强MRI扫描，记录肿瘤控制及并发症发生情况。 结果 131例患者完成随访，平均随访时间49个月。至随访结束，共7例患者肿瘤增大复发。伽玛刀治疗后1、2、3、4及5年肿瘤控制率分别为95.8%、95.8%、95.8%、95.8%及93.9%。46例患者（35.1%）在治疗后出现暂时性头痛和感觉异常，对症处理后缓解；4例患者（3.1%）出现垂体功能低下，接受激素替代治疗。未观察到其他颅神经和血管损害表现。 结论 伽玛刀治疗垂体瘤远期疗效肯定，并发症轻微，是一种安全可靠的垂体瘤治疗手段。【Abstract】 Objective To explore the long-term tumor control and side effects of gamma knife treatment for pituitary adenoma. Methods One hundred and fifty-eight patients with pituitary adenoma undergone gamma knife treatment were periodically followed up from June 2004 to December 2006. The prescript radiation dosage was 12-30 Gy. An enhanced MRI scan was scheduled every 6-12 months after the treatment. The tumor sizes of different scan were compared and the side effects were recorded. Results One hundred and thirty-one patients finished the follow-up procedure with an average time of 49 months. One hundred and twenty-four patients received good tumor control at the end of the research and recurrence was seen in seven patients. The 1-, 2-, 3-, 4-, and 5- year tumor control rates were 95.8%, 95.8%, 95.8%, 95.8%, and 93.9% respectively. Forty-six patients showed temporal and were relieved after treatment. Hypopituitarism was seen in four patients but no cranial nerve or vascular damage was detected. Conclusion The long-term effect of gamma knife therapy for pituitary adenoma remains good and the incidence of side effects is low. Gamma knife therapy could be a safe and effective choice for pituitary adenoma treatment.
摘要:目的:总结巨大垂体腺瘤水钠代谢紊乱的围手术期处理经验。方法:对71例巨大垂体腺瘤患者术前及术后1周内每日检测血、尿电解质水平,以及血、尿渗透压,判断失钠及失水类型。总结不同瘤体大小与手术入路和水钠紊乱发生率、程度、时间之间的关系。结果:71例巨大垂体腺瘤患者中,出现水钠代谢紊乱52例,发生率73.2%。肿瘤大小与水钠紊乱发生率、严重程度、发生时间成正比,而手术入路选择与水钠代谢紊乱发生无明显相关。结论:巨大垂体腺瘤患者术后水钠代谢紊乱的发生与瘤体大小成正相关,其出现时间和表现形式复杂。对水钠代谢紊乱严重患者可适当予以预防性治疗,以减少临床症状和不良后果。Abstract: Objective: To summarize the preioperative management experience of metabolic disturbance of water and natrium for patients with giant pituitary adenomas. Methods: The electrolyte and osmotic pressure of blood and urine in patients with giant pituitary adenomas were detected within preoperative and postoperative one week and the type of the metabolic disturbance of water and natrium were determined. The correlation of the different tumor size and surgical approach with the incidence rate, extent and time of the metabolic disturbance was summarized. Results: There were 52 cases with different extent metabolic disturbance of water and natrium in 71 cases of giant pituitary adenomas(73.2%). There were a positive correlation of tumor size with the incidence rate, extent and time of the metabolic disturbance, and a negative correlation of surgical approach with that of the metabolic disturbance. Conclusion: The metabolic disturbance of water and natrium in giant pituitary adenomas was positive correlation with the tumor size, which. is various in emergence time and pattern of manifestation. To reduce the clinical symptoms and adverse consequences, prophylactic treatment may be used in patients with serious metabolic disorder of water and natrium.
摘要:目的:探讨神经内镜经单鼻腔蝶窦入路在切除垂体腺瘤中的临床应用。 方法:对58例垂体腺瘤患者进行手术切除。应用神经内镜直接自单鼻腔进入,暴露双侧蝶窦开口,打开蝶窦前壁进入蝶窦腔切除肿瘤。 结果: 肿瘤全部切除42例,约占 72%;次全切除16例,约占28%,无严重并发症。结论:神经内镜经单鼻腔蝶窦入路切除垂体腺瘤是一种更微创、暴露更好、并发症少的手术方式。Abstract: Objective: To investigate the clinic application of endoscopic end nasal transsphenoidal surgery for pituitary tumors. Methods: 58 patients were treated. A endoscope was used to open the anterior wall of the sphenoid sinus and resected tumors. Results: 42 cases (72%) underwent total resection, 16 cases (28%) underwent subtotal resection. No severe complications was found. Conclusion: Endoscopic end nasal transsphenoidal surgery for pituitary tumors can reduce the tissue trauma, improved visualization, more complete tumor removal, and reduce complications.
ObjectiveTo explore the effectiveness of the usage of artificial bone of tricalcium phophate in sellar floor reconstruction after transsphenoidal microsurgery for pituitary adeoma. MethodsBetween January and December 2014, 85 patients with pituitary adema underwent transsphenoidal microsurgery, and the clinical data were retrospectively analyzed. "Sandiwich" was used for sellar floor reconstruction in 46 cases (control group), and "sandiwich" combined with the artificial bone of tricalcium phophate in 39 cases (trial group). There was no significant difference in gender, age, disease duration, size of tumor, invasiveness, and the degree of damage to the sellar floor between 2 groups (P>0.05). ResultsTotal removal and subtotal removal of tumors were achieved in 39 cases and 7 cases of the control group, and in 33 cases and 6 cases of the trial group, showing no significant difference between 2 groups (Z=-1.303, P=0.193). Cerebrospinal leakage occurred in 8 cases of the control group and in 10 cases of the trial group during operation, showing no significant difference (Z=-1.748, P=0.080). The case number of cerebrospinal leakage in the control group (4 cases) was significantly more than that in the trial group (0) after operation (P=0.020). The time of gauze removal in the trial group (3 days) was significant shorter than that in the control group[(4.3±1.6) days] (t=2.236, P=0.033). The patients were followed up 3-14 months in the control group and 5-13 months in the trial group. No cerebrospinal leakage occurred during follow-up. ConclusionSellar floor reconstruction with artificial bone of tricalcium phophate is safe, and it can reduce cerebrospinal leakage and shorten the time of gauze removal.
ObjectiveTo explore the value of bilateral inferior petrosal sinus sampling (BIPSS) for preoperative diagnosis of adrenocorticotropic hormone (ACTH) microadenomas.MethodsWe retrospectively analyzed the clinical date of patients with ACTH microadenomas, who were experienced BIPSS preoperatively from October 2013 to May 2017. The qualitative and localized diagnostic significance of BIPSS was evaluated based on the criteria of the plasma ACTH concentration ratio of inferior petrosal sinus to ulnar vein (≥2), and the ratio of left to right inferior petrosal sinuses (≥1.4).ResultsFive patients (1 male and 4 females) were involved in the study. The mean age was (49.6±9.2) years, and the mean disease course was (17.2±7.5) months. The plasma ACTH concentration of all the cases ran up to the criterition of the ratio of inferior petrosal sinus to ulnar vein (≥2). Three cases were found that the actual locations of the microadenomas were inconsistent with the indications from the results of BIPSS. After the BIPSS procedure, there was no intracranial infection or death case, except that one patient suffered from ecchymoma and another one suffered from transient nausea.ConclusionBIPSS is valuable for qualitative diagnosis, but not effective for localization diagnosis of the ACTH microadenomas preoperatively.
