The influence of configuration and location of ruptured distal cerebral anterior artery aneurysms on their treatment modality and results: analysis of our casuistry and literature review.

Objective: To assess the influence of configuration and location of ruptured distal cerebral anterior artery aneurysms on their treatment modality and results.

Method: The influence of the aneurysm configuration (basic or complex configuration) and location (infracallosal or supracallosal) on the treatment-related radiological results (partial or complete aneurysm occlusion) and clinical outcome (favorable or unfavorable) was retrospectively analysed in all admitted patients with ruptured pericallosal aneurysms within the last 10 years. The expected benefit from each form of treatment was individually discussed.

Unusual sequestered disc fragments simulating spinal tumors and other space-occupying lesions. Clinical article.

Object: In this study the authors evaluated disease incidence, treatment, and outcome in patients with unusual sequestered disc fragments simulating spinal tumors or another space-occupying lesion on preoperative MR imaging.

Methods: The authors retrospectively reviewed data from the last 3000 patients with a histological diagnosis of disc herniation. Patients with preoperative MR imaging findings that simulated a spinal tumor or other space-occupying lesion were individually analyzed.

Atypical causes of nontraumatic intracranial subarachnoid hemorrhage.

Background: To analyze the management and outcome of patients presenting with atypical causes of intracranial subarachnoid hemorrhage (SAH).

Methods: We performed a review of our last 820 nontraumatic-SAH patients and analyzed the management and outcome of patients where the SAH origin was not a ruptured aneurysm. The Glasgow Outcome Scale (GOS) was used to assess outcome 3 months after event.

Interdisciplinary treatment selection in admitted patients with acute subarachnoid hemorrhage.

Objective: To review the angiographic and clinical outcomes from acute (first 6 hours after bleeding) interdisciplinary treated patients with ruptured intracranial aneurysm.

Method: An interventional neuroradiologist and a neurosurgeon set the emergent treatment of 100 consecutive patients with subarachnoid hemorrhage (SAH) harboring 111 cerebral aneurysms. Decisions were based on the patient's clinical condition, aneurysm's morphology and location, presence of intracranial mass-occupying process (IMOP), angiographic flow distribution patterns and treatment-related risk profit.

Acute management of poor condition subarachnoid hemorrhage patients.

Poor condition subarachnoid hemorrhage (SAH) patients present a high mortality and morbidity. In this study, we reviewed the acute interventional (surgical and endovascular) management of 109 SAH-poor condition patients, who were treated as early as logistically possible after confirming stable circulation parameters. Patients over the age of 70 years, without clinical response to painful stimulation were excluded.

Volume assessment of intracranial large meningiomas and considerations about their microsurgical and clinical management.

Objective: To assess the volume of large intracranial meningiomas and analyse their different microsurgical and clinical managements.

Method: The volume of 45 large meningiomas treated in our department during the last 9.5 years was retrospectively assessed using recorded neuronavigation data.

Unruptured large intracranial aneurysms in patients with transient cerebral ischemic episodes.

This report analyzes the treatment of six patients with transient cerebral ischemic episodes in combination with large unruptured aneurysm. Priority treatment of the symptomatic lesions had to be delayed in five cases because the large aneurysms were ipsilateral to stenoses of the internal carotid artery. The hemodynamic effect of surgery on the compromised cerebral circulation was pre-examined with digital subtraction angiography and technetium-99m ((99m)Tc) single photon emission computed tomography.
