Separation of conjoined spinal cords in symmetrical pygopagus twins using intraoperative neuromonitoring: pearls and pitfalls.

Pygopagus twin is a rare congenital malformation with a worldwide incidence of 1in 200,000. Few literature reports are published regarding the matter. In some cases, neuromonitoring is essential for safe surgical separation.

Awake craniotomy for epilepsy surgery on eloquent speech areas: a single-centre experience.

In patients with intractable partial epilepsy who are eligible for epilepsy surgery, the best seizure control requires complete resection of the epileptogenic zone. When the epileptogenic zone is located very near to, or even with the eloquent cortex, this can be a challenge. In this study, we investigated the efficacy of awake craniotomy techniques to completely resect these epileptic zones while preserving the neural functions.
