Decompressive craniectomy (DC) has been proposed as a lifesaving treatment in patients with elevated intracranial pressure, but its effectiveness on reaching a favorable neurologic outcome remains unclear. We identified predictors of outcome in a large, single-center cohort of patients undergoing DC for different pathologic conditions. ⋯ Long-term neurologic outcome after DC differed remarkably among subpopulations of patients, with favorable outcome rates ranging from 0% to >90%.

"On the spot": the use of 4D-CTA to differentiate a true "spot sign" from a distal intracranial aneurysm.
Spontaneous intracerebral hemorrhage may arise from underlying abnormalities, including aneurysms. Computed tomography angiography (CTA) is widely used for the detection of possible underlying causes, which is important because it may have immediate therapeutic consequences. In addition, CTA is used to detect the so-called spot sign, indicating active hemorrhage, which carries a worse prognosis. However, CTA is a snapshot in time. Four-dimensional (4D) CTA is a dynamic type of imaging and has emerged as a valuable imaging technique for different neurovascular disorders. ⋯ Our case findings show how 4D-CTA can discern active bleeding from aneurysmal hemorrhage in cases with hemorrhagic stroke. This finding proves the additional value of this relatively new technique, because the detected underlying disorders have different therapeutic consequences in the acute setting.

Patients with Moyamoya or other intracranial steno-occlusive disease are at risk for developing aneurysms associated with flow through collateral vessels. Because these lesions are rare, the optimal management remains unclear. Here, we describe 2 cases of microsurgical repair of ruptured collateral vessel aneurysms associated with middle cerebral artery (MCA) occlusion. ⋯ Our experience suggests that patients with MCA occlusion can harbor associated aneurysms related to flow through collateral vessels and can present with hemorrhage. Microsurgical repair of these aneurysms can be performed safely to prevent rebleeding.

In symptomatic unruptured intracranial aneurysms (UIAs), data on long-term functional outcome are sparse in the literature, even in the light of modern interdisciplinary treatment decisions. We therefore analyzed our in-house database for prognostic factors and long-term outcome of neurologic symptoms after microsurgical/endovascular treatment. ⋯ This recent study presents for the first time a detailed analysis of relevant prognostic factors for long-term recovery of cranial nerve/brainstem compression symptoms in an interdisciplinary treatment concept, which was excellent in most patients, with lowest recovery rates in optic nerve compression. Symptom recovery was remarkably higher in the long-term compared with recovery at discharge.

Occipital neuralgia is a chronic pain syndrome characterized by sharp, shooting pains in the distribution of the occipital nerves. Although relatively rare, it associated with extremely debilitating symptoms that drastically affect a patient's quality of life. Furthermore, it is extremely difficult to treat as the symptoms are refractory to traditional treatments, including pharmacologic and procedural interventions. A few previous case studies have established the use of a neurostimulation of the occipital nerves to treat occipital neuralgia. ⋯ Despite complications, the results suggest, overall, that occipital nerve stimulation is a safe and effective procedure for refractory occipital neuralgia and should be in the neurosurgical repertoire for occipital neuralgia treatment.
