Neurosurgical Steps and Lessons Learned in Final Separation of 3-Year-Old Craniopagus Twins.

The only published paper describing the separation of the conjoined twins did not describe the novel steps and techniques of the microsurgery part, which lasted 26 hours. That paper did not include the neurosurgical video, either. The massive intracerebral hemorrhage that occurred on postoperative day 33 was not reported, and its potential causes have not been scrutinized.

[Preoperative embolisation of spinal metastases].

In the management of spinal metastases bringing about neurological symptoms and signs, palliative surgical treatment plays an important role. The goals of surgery are preservation of neurological function especially that of the mobility, pain relief and local tumor control. Many of spinal metastases are hypervascularised, accordingly, preoperative embolisation offers logically improvement in technical realisation of surgery by means of reduction of intraoperative profuse bleeding.

Cerebral arterial fenestrations: a common phenomenon in unexplained subarachnoid haemorrhage.

Background: Fenestrations of intracranial arteries are variants resulting from incomplete fusion of vessels during development with unknown clinical significance. They are best visualised with 3D rotational angiography (3DRA).

Objective: In a prospective consecutive series of patients with suspected aneurysms, 3DRA was performed to identify not only the potential bleeding source but also to assess the frequency and location of any fenestrations of intracranial arteries.
