Recently, it was reported that fenestration of the lamina terminalis (LT) may reduce the incidence of shunt-dependent hydrocephalus in aneurysmal subarachnoid hemorrhage (SAH). The authors investigated the efficacy of the LT opening on the incidence of shunt-dependent hydrocephalus in the ruptured anterior communicating artery (ACoA) aneurysms. The data of 71-ruptured ACoA aneurysm patients who underwent aneurysmal clipping in acute stage were reviewed retrospectively. Group I (n=36) included the patients with microsurgical fenestration of LT during surgery, Group II (n=35) consisted of patients in whom fenestration of LT was not feasible. The rate of shunt-dependent hydrocephalus was compared between two groups by logistic regression to control for confounding factors. Ventriculo-peritoneal shunts were performed after aneurysmal obliteration in 18 patients (25.4%). The conversion rates from acute hydrocephalus on admission to chronic hydrocephalus in each group were 29.6% (Group I) and 58.8% (Group II), respectively. However, there was no significant correlation between the microsurgical fenestration and the rate of occurrence of shunt-dependent hydrocephalus (p>0.05). Surgeons should carefully decide the concomitant use of LT fenestration during surgery for the ruptured ACoA aneurysms because of the microsurgical fenestration of LT can play a negative role in reducing the incidence of chronic hydrocephalus.

OBJECTIVETo investigate the techniques and effect of surgical resection of large intra- and extra-ventricular craniopharyngiomas via anterior interhemispheric trans-lamina terminalis approach.

METHODSFifty-two patients who were surgically treated for large intra- and extra-ventricular craniopharyngiomas were retrospectively analyzed. All patients underwent surgery via anterior interhemispheric trans-lamina terminalis approach. Of the 52 patients, 28 were male and 24 were female, with age ranging from 3 to 67 years (mean age 33.5 years). The maximum tumor diameter varied from 4.0 to 7.8 cm, with mean diameter of 5.1 cm. Contrast-enhanced MRI was underwent to determine the extent of tumor resection on the 1 to 3 months after surgery.

RESULTSTotal removal of the lesion was achieved in 47 cases (90.4%), 5 patients underwent subtotal resection (9.6%). Division of the anterior communicating artery was performed in 6 patients with no early or late complications related to division of the artery. Visual acuity was preserved or improved in 44 patients (84.6%). Preservation of the pituitary stalk were achieved in 33 patients (63.5%). No surgery-related deaths occurred. The postsurgical follow-up period varied from 3 months to 68 months (mean 25.4 months). Twenty-three cases had endocrinological deficit and received some form of hormonal replacement after surgery. Permanent diabetes insipidus occurred in 18 cases. Three patients died and 6 patients suffered recurrence during the followed-up period.

CONCLUSIONSThe anterior interhemispheric approach, with opening of the lamina terminalis, is a valid choice for large intra- and extra-ventricular craniopharyngiomas. These tumors can be removed without significant sequelae related to the surgical approach because optic nerves, optic chiasm, internal carotid artery, hypothalamic structures and pituitary stalk can be seen and effectively protected.

OBJECTIVETo investigate the growth of craniopharyngioma involving the third ventricular floor with regard to the hypothalamus by detecting expressions of leukocyte common antigen (CD45) and intercellular adhesion molecule (ICAM-1) in the tumor tissue.

METHODSThe expressions of CD45 and ICAM-1 proteins in 30 craniopharyngioma samples with third ventricular floor involvement were detected by SP immunohistochemistry.

RESULTSThe inflammations labeled by CD45 were identified commonly in the craniopharyngioma tissues involving the third ventricular floor. The expression of ICAM-1 was mainly in the inner tumor cells and interstitial cells, but not detected in the basilar tumor cells growing toward the third ventricular floor. Adamantinomatous craniopharyngiomas showed markedly higher CD45 and ICAM-1 expressions than squamous papillary tumors (P<0.05).

CONCLUSIONInflammatory adhesion largely characterizes the growth of the craniopharyngioma tissues involving the third ventricular floor toward the hypothalamus without the tendency of invasion. The difference in the inflammation between the two types of craniopharyngioma may affect the prognosis of the patients.

Prader-Willi syndrome is a well known multi-systemic disorder featuring hypothalamic dysfunction and hypotonia with underlying chromosomal anomaly. High morbidity, early mortality due to complications as diabetes mellitus, hypertension, athero-sclerosis, and cardio-respiratory failure have been reported from poorly tolerated obesity and combined metabolic disorders. We experienced a 20-year- old girl with Prader-Willi syndrome diagnosed at the age of 7. She underwent massive, uncontrolled weight gain despite constant multi-drug therapy including human recombinant growth hormone, orlistat, sibutramine and combined behavioral managements. Her body weight reached 104 kg and she developed dyslipidemia, fatty liver, hypertension, diabetes mellitus and episodes of sleep apnea. She showed no significant response to the supportive treatment because of characteristic involvement in CNS especially hypothalamus and psycho-behavioral disorders. As Bariatric surgery was the most effective and curative method in treatment of severe morbid obesity, Roux-en-Y gastric bypass was performed. After the operation, she showed substantial weight loss and consequent improvements in obesity related complications. She could stop all medications concerning for obesity. We report a case of bariatric surgery on a girl with Prader-Willi syndrome and combined severe morbid obesity who underwent bariatric surgery which resulted in marked weight loss and improvements in associated complications.
