PURPOSE: To determine the usefulness of mechanically detachable spiral tungsten coils (MDSs) in the endovascular, endosaccular occlusion of intracranial aneurysms. MATERIALS AND METHODS: Anterior communicating artery aneurysms shown at angiography in two patients and a basilar tip aneurysm shown in one patient were treated with MDSs. RESULTS: In the basilar artery aneurysm, eight coils were delivered. Two additional coils were placed at 3 months because of filling of the residual aneurysm neck. Angiography at 1 year showed no recanalization. The smaller aneurysm in the anterior communicating artery was totally occluded by a single coil. Angiography at 6 months showed no recanalization. The other aneurysm was occluded by two coils, with a small amount of residual filling. A third coil was withdrawn before detachment. The patient had aspiration pneumonia and electrolyte imbalance, but he was in stable condition 3 weeks later and was discharged. CONCLUSION: The pliable, soft, retrievable MDS system provides instantaneous release of a spiral coil.

Primary intracranial germ cell tumors in children: a report of eight cases and review of the literature.

This study was conducted to evaluate the signs and symptoms on admission, diagnosis, localization, therapy, and survival of patients with primary intracranial germ cell tumors (PICGCT). Eight patients with surgically confirmed PICGCTs were treated and followed up at Hacettepe University's Department of Pediatric Oncology between 1974 and 1995. While one patient was admitted with a second recurrence of her disease, the others were admitted or referred primarily to our institution. In this period, 357 germ cell tumor and 684 primary intracranial malignant tumors were diagnosed and treated at our institution. Thus, PICGCTs comprised 1.1 percent of the primary intracranial malignant tumors and 2.2 percent of the germ cell tumors. There were four females and four males and the median age was eight years (13 months to 12 years). On admission, the most common symptoms were diabetes insipidus (3/8) and vomiting (3/8). One patient also and Down's syndrome. Locations of the tumors were suprasellar in three, in the third ventricle in two, and in the cerebral parenchyma, and pineal and hypothalamic regions in the remainder. There were germinomas, three malignant teratomas, and two mixed germ cell tumors. Only two patients could be treated with appropriate and adequate chemotherapy and radiotherapy. Three patients died: one in the postsurgical period, one after the third surgical approach and one 11 months after the diagnosis of progressive disease; three were lost to follow-up. The remaining two patients (with second recurrence and disseminated disease) are alive and without disease. Our experience with these patients demonstrated that appropriate and adequate chemotherapy is as effective a treatment as radiotherapy, even with recurrence of the disease.

Craniosynostosis: a review of 143 surgically-treated cases.

In this study, 143 cases of craniosynostosis are presented. There were 109 males and 34 females. The major complaints were skull deformity (92 patients), proptosis (38 patients) and microcephalus (32 patients). Neurological examination revealed the presence of optic atrophy in 24 patients and papilledema in 20 patients. Seventy-four patients (53%) had three or more suture closures, with the sagittal suture being the most commonly involved (20% of patients). All patients underwent surgery. Suture removal was performed in 131 patients (91.7%), suture removal plus orbital decompression in 34 (23.8%), and linear craniectomy plus wrapping in 12 (8.3%). The reoperation rate was 6.2 percent. During the follow-up period, preoperative papilledema and proptosis improved in 88.2 and 78.9 percent of patients, respectively. Skull deformity disappeared in 46.9 percent of patients, but remained unchanged in 16.6 percent.
