Decompressive Craniectomy After Aneurysmal Subarachnoid Hemorrhage (DECIDE-SAH)

Más betegség

• Non-aneurysmal subarachnoid hemorrhage, including subarachnoid hemorrhage caused primarily by another vascular lesion without a qualifying ruptured intracranial aneurysm.
• Traumatic subarachnoid hemorrhage.

Életkor

• Age below 18 years.

Egyéb

• Rupture of an infectious/mycotic intracranial aneurysm.
• Rupture of a traumatic pseudoaneurysm.
• Rupture of an iatrogenic pseudoaneurysm.
• Rupture of an AVM-/AVF-associated flow-related aneurysm.
• Source information insufficient to establish the qualifying aSAH diagnosis or to meet the Minimum Required Dataset threshold.
  • Pregnancy, acute lack of decision-making capacity during the original aSAH episode, and non-German language are not exclusion criteria for this retrospective secondary use of pre-existing routine-care data.

• Age 18 years or older at ictus or hospital admission.
• Confirmed aneurysmal subarachnoid hemorrhage caused by rupture of a qualifying intracranial aneurysm.
• Eligible qualifying aneurysm morphologies include saccular, blister-like, dissecting, fusiform, and other non-excluded aneurysmal morphologies.
• Treatment or clinical management at a participating center during its documented consecutive retrospective cohort period.
• Availability of the Minimum Required Dataset (MRD) for scientific cohort contribution. The MRD requires a technical center-specific study identifier without direct identifiers, an index time period for the qualifying aSAH episode, age, sex, initial clinical severity represented by an accepted grading scale or valid Good Grade/Poor Grade classification, aneurysm-treatment status and modality, decompressive-craniectomy status, and at least one interpretable discharge clinical outcome.
• Complete Standard Dataset or Extension Module information is not required for cohort eligibility. Six-month mRS is not required for participation in analyses that do not use the registered primary endpoint.
