Recent studies have reported the use of stent-assisted coiling (SAC) for wide-necked aneurysms in patients with acute subarachnoid hemorrhage (SAH). This study attempted to determine whether it is safe and efficient to use SAC for wide-necked aneurysms during post-SAH days 4-10. ⋯ Patients with ruptured wide-necked aneurysms treated on posthemorrhage days 4-10 did not appear to have worse outcomes compared to patients treated on posthemorrhage days 0-3.

Vasospasm after craniopharyngioma surgery, although rare, has been reported. Hypotheses regarding possible causative factors, including major vessel handling during surgery and tumor cyst fluid spillage, do not explain vasospasm occurring in the late postoperative period. We have attempted to consider the probable pathogenic mechanisms of this complication and measures to prevent it. ⋯ Major vessel handling during radical craniopharyngioma surgery is likely to predispose them to spasm, accentuated by rapid shifts of fluid and electrolytes during different phases of DI. This is further complicated by a relative hypocortisolic state caused by tendency to taper off steroids early. Hypocortisolism masks DI leading to dehydration and possibly vasospasm. Once vasospasm develops, it is not easy to reverse. Radiologic reversal with intra-arterial nimodipine may not translate into a good clinical response. Therefore, prudence lies in its prevention. Close monitoring of fluids and electrolytes with optimal steroid cover is necessary until stabilization of DI to prevent this complication.

Percutaneous endoscopic surgery is increasingly used as an alternative to open microsurgery for treating lumbar spinal diseases. The purpose of this study was to determine the feasibility and efficacy of contralateral keyhole endoscopic surgery for treating unilateral radiculopathy. ⋯ Contralateral keyhole endoscopic surgery is a safe and useful technique to decompress unilateral lateral recess stenosis or facet cyst.
