Controlled Clinical Trial
A population-based study of neurosurgical and endovascular treatment of ruptured, intracranial aneurysms in a small neurosurgical unit.
Since the introduction of endovascular embolization, the optimal treatment of ruptured aneurysms has been debated. Much of this debate has been based on results from large neurovascular centers and may not be applicable to small neurosurgical centers with low annual aneurysm loads. We think that the results of small centers, such as ours, may also be of some interest. ⋯ At present in our hospital, the endovascular modality seems to yield a better clinical outcome than surgery and has become our treatment of choice. With increasing use and further refinement of the endovascular techniques, the difference in outcomes between the treatment modalities will probably change even further in favor of the endovascular technique.

Medically refractory cluster headache (CH) is a debilitating condition for which few surgical modalities have proven effective. Previous reports involving short-term follow-up of CH patients have reported modest degrees of pain relief after radiosurgery of the trigeminal nerve ipsilateral to symptom onset. With the recent success of deep brain stimulation as a surgical modality for these patients, it becomes imperative for the long-term risks and benefits of radiosurgery to be more extensively delineated. To address this issue, we present our findings from the largest retrospective series of patients undergoing radiosurgery for CH with extended follow-up periods. ⋯ Although some patients may experience short-term pain relief, none had relief sustainable for longer than 2 years. The results from this series indicate that radiosurgery of the trigeminal nerve does not provide long-term pain relief for medically refractory CH.

Blast-related neurotrauma is associated with the severest casualties from Operation Iraqi Freedom (OIF). A consequence of this is cerebral vasospasm. This study evaluated all inpatient neurosurgical consults related to battle injury from OIF. ⋯ Traumatic vasospasm occurred in a substantial number of patients with severe neurotrauma, and clinical outcomes were worse for those with this condition. However, aggressive open surgical and endovascular treatment strategies may have improved outcome. This was the first study to analyze the effects of blast-related injury on the cerebral vasculature.

To analyze treatment procedures and treatment outcomes of painful missile-caused nerve injuries and factors influencing the outcome. ⋯ The treatment outcome of painful nerve injury depends on several factors, including the type of pain syndrome, severance of nerve injury, and absence of pain paroxysms. Drug therapy (carbamazepine, amitriptyline, or gabapentin) should be recommended, at least as a part of treatment, for patients with reinnervation pain, deafferentation pain, and complex regional pain syndrome Type II. Nerve surgery should be recommended for patients with posttraumatic neuralgia, either as the first treatment choice (acute nerve compression or intraneural foreign particles) or after unsuccessful pharmacological treatment (other causes of neuralgic pain).

To report on the clinical characteristics of pain and factors influencing pain intensity in patients with missile-caused nerve injuries. ⋯ Pain syndromes after missile-caused nerve injury differ significantly regarding time of pain onset, pain characteristics, and other symptoms and signs. The type of pain syndrome, multiple nerve damage, and early onset of pain are independent predictors of initial pain intensity. Although medical history and physical examination are the main diagnostic keys, nerve exploration preceded by a nerve block and sympathetic block are safe and useful adjuvant diagnostic procedures.
