OBJECTIVETo investigate the clinical features, surgical transcranial approaches and outcomes of giant pituitary adenomas.
METHODSA series of 112 consecutive cases of giant pituitary adenomas underwent microsurgery through transcranial approaches at People' s Liberation Army General Hospital were retrospectively analyzed. Of the 112 patients, 58 were male and 54 were female, with age ranging from 3 to 72 years(mean age 44. 3 years). There were 91 non-functioning adenomas and 21 hormone-secreting adenomas. The maximum tumor diameter varied from 4. 0 to 7. 2 cm, with mean diameter of 4. 8 cm. Unilateral subfrontal approach was chosen in 16 cases, pterional approach in 41 cases, anterior interhemispheric approach in 34 cases, transcallosal-interforniceal approach in 6 cases, transcortical- transventricular approach in 5 cases, combined approach in 6 cases and other approaches in 4 cases. Postoperative MRI and endocrine function were re-examined routinely to evaluate the therapeutic efficacy. Staged operation through transsphenoidal approach or adjuvant treatments including medical and radiation therapies were administered in patients with hormone-secreting adenomas when hormonal excess persisted after surgery and in patients with non-functioning adenomas who had postoperative MRI evidence of residual tumor.
RESULTSTotal removal of the lesion was achieved in 57 cases (50. 9%) , 26 patients (23. 2%) underwent subtotal resection, and 29 patients (25. 9%) underwent partial removal. Postoperative mortality occurred in 3 patients (2. 7%). Major surgical morbidity occurred in 38 patients (33. 9%). Vision was preserved or improved in 98 patients (87. 5%). The postsurgical follow-up period varied from 3 to 64 months (mean 19. 5 months) . Nineteen of the 21 patients with hormone-secreting adenomas were considered to be in hormonal remission, and 87. 2% of the cases were capable of normal work and life and 8 patients suffered recurrence during the followed-up period.
CONCLUSIONSSelection of appropriate transcranial approaches is the key to successful microsurgery for giant pituitary adenomas according to the morphological characteristics presented in image examinations and clinical symptoms. Staged transsphenoidal operation and/or adjuvant therapies including medical and radiation therapies offer the best chances to control the residual tumors after the maximal surgical removal of giant adenomas through transcranial approaches.

Objective To summarize the experiences of microsurgery for treatment of middle cerebral artery aneurysms (MCAA). Methods The clinical data of 35 patients with MCAA treated by microsurgery in General Hospital of PLA from 2004 to 2008 were retrospectively reviewed. Of them there were 20 males and 15 females, aged 18 to 72 years with a mean of 40 years. Of the 35 patients, subarachnoid hemorrhage occurred formerly in 22, intracerebral hemorrhage occurred in 11 and subdural hematoma in one patient. The MCAA located in the middle cerebral artery trunk in 10 patients, at the bifurcation in 20 patients (including one patient with 2 MCAAs), and in the distal segment in 5 patients. MCAA located on the left side in 13 and on right side in 22 patients. There were 7 patients with giant aneurysms, 11 with large aneurysms and 17 with small aneurysms. Microneurosurgery was performed in all cases, and different approaches were taken according to the locations of aneurysms. Superior temporal gyrus approach was conducted in 3 patients with giant intracerebral hematoma. Bypass of superficial temporal artery to middle cerebral artery was performed before occlusion of the afferent artery in one patient with giant aneurysm. Bypass with saphenous vein to middle cerebral artery was performed in another patient with giant aneurysm. Results The giant and large MCAAs consisted of 51.4% of all cases. Excellent outcomes were achieved in 20 patients, no marked change in 12 patients, and post-operative complications were observed in 3 patients. No perioperative death occurred. Conclusions Giant and large aneurysms are more common in middle cerebral artery aneurysms. Proper surgical approaches based on different situations during operation should be considered to achieve satisfactory outcome.
