DAVF's at the SSS are extremely rare and usually present with intracranial haemorrhage (ICH) or a progressive neurological deficit. Due to their midline location and multiple arterial supply, endovascular treatment alone often fails in eliminating the fistula. Therefore, endovascular, combined with neurosurgical and/or radiosurgical treatment is often needed to cure the patient. We summarized our experience with three male patients over a ten-year period who suffered from dAVF's involving the middle and posterior third of the SSS. Two of them presented with an ICH during the clinical course. Despite multiple transarterial embolisations, complete fistula occlusion could not be achieved in any of them. Nevertheless, neurological symptoms improved in all cases. One patient refused further treatment and died six years later due to an ICH. Another patient was finally cured by microsurgical coagulation of the fistula. In the remaining patient stereotactic radiosurgery (SRS) was performed after nearly complete endovascular occlusion. We strongly recommend microsurgery and/or radiosurgery as adjunctive measures, if embolisation alone fails to eliminate these dangerous fistulae.

Controversy surrounds the treatment of recurrent cubital tunnel syndrome after previous surgery. Irrespective of the surgical technique, namely pure decompression in the ulnar groove and the cubital tunnel distal of the medial epicondyle, and the different methods of volar transposition (subcutaneous, intramuscular, and submuscular), the results of surgical therapy of cubital tunnel syndrome are often not favorable, especially in cases of long-standing symptoms and severe deficits. Twenty-two patients who had previously undergone surgical treatment for ulnar nerve entrapment at the elbow were evaluated because of persistent or recurrent pain, paresthesia, numbness, and motor weakness. Ten patients had undergone a nerve transposition, 5 patients underwent a simple decompression of the ulnar nerve, and 7 patients experienced two previous operations with different surgical techniques. Two patients underwent surgery at our hospital, whereas 20 patients underwent their primary surgery at other institutions. Various surgical techniques were used during the subsequent surgery, such as external neurolysis, subcutaneous anterior transposition, and subsequent transfer of the nerve back into the sulcus. The causes of continued or recurrent symptoms after initial surgery included dense perineural fibrosis of the nerve after subcutaneous transposition, adhesions of the nerve to the medial epicondyle and retention of the medial intermuscular septum. The average follow-up after the last procedure was 7 months (2 - 20 months). All 7 patients with subsequent transfer of the ulnar nerve back into the sulcus became pain-free, whereas only 11 of 15 patients who had external neurolysis or subcutaneous transposition became free of pain or experienced reduced pain. The recovery of motor function and return of sensibility were variable and unpredictable. In summary, reoperation after primary surgery of cubital tunnel syndrome gave satisfactory results in 18 of 22 cases. Subsequent transfer of the ulnar nerve back into the sulcus promises to be useful in cases in which subcutaneous transposition had not been successful.

An endoscopic endonasal technique was used in the surgical treatment of a meningioma compressing the optic nerve. The patient was a 58-year-old woman who had experienced progressive visual loss in her left eye. Magnetic resonance (MR) scans of the brain demonstrated a contrast-enhancing tumor mass, which was measured to be 10 × 15 mm in size, compressing the left optic nerve. Automated visual field examination confirmed left-eye visual field defects, the temporal visual field worse than the nasal. The tumor was excised in total endoscopically through her right nostril. Histological diagnosis was meningothelial meningioma. Her hospital stay was overnight. Her left-eye vision improved with a residual crescentic temporal-field defect. She has done well without tumor recurrence as evidenced by a 20-month follow-up. This is the first report describing endoscopic endonasal removal of an intracranial tumor compressing the optic nerve.

Various surgical approaches to treat intraventricular cysticercosis have been practiced over the years. We now present our experience with the use of the endoscope in the removal of intraventricular cysticercal cysts in patients with intraventricular cysticercal lesions associated with hydrocephalus. From 1995 to 1998, we have excised intraventricular cysticercal cysts from 9 patients. They were located in lateral ventricle in 4, in the third ventricle in two and in the fourth ventricle in three patients. A Gaab's rigid neuroendoscope system was used to enter and excise cysts in the lateral and third ventricle. The flexible fiberoptic scope was used for excising cysts in the fourth ventricle, through a transaqueductal route. In all cases a precoronal frontal burr hole was used for entry. All have been treated with albendazole in the postoperative period. All the cysts were removed successfully using endoscopic neurosurgery alone. One patient had a superficial injury to the rigid side of the aqueduct with a postoperative deficit, which improved. Three septal perforations, three third ventriculostomies, and one aqueductoplasty were done in the same sitting after cyst removal for CSF diversion. None of the nine cases required further surgery up to date. The follow-up period varied from 12 to 45 months with a median of 18 months. Endoscopic neurosurgery is a minimally invasive technique enabling removal of intraventricular cyticercal cysts from all locations, avoiding major craniotomies/posterior fossa explorations and shunts.
