Rates of complications requiring emergent neurosurgical intervention according to per-procedure analysis
| Procedure | No. | Complication (%) | Neurosurgical Procedure |
|---|---|---|---|
| Ruptured intracranial aneurysm embolization | 134 | 2 (1.50%) | Immediate (n = 2), EVD, adjunctive (n = 0) |
| Unruptured intracranial aneurysms embolization | 98 | 2 (1.02%) | Immediate (n = 1), EVD adjunctive (n = 1) EVD plus DC |
| Intracranial angioplasty/stent placement | 92 | 1 (2.17%) | Immediate (n = 0), EVD adjunctive (n = 2) EVD |
| Acute ischemic stroke treatment | 165 | 1 (0.60%) | Immediate (n = 0), adjunctive (n = 1) EVD |
| AVM embolization | 34 | 1 (2.94%) | Immediate (n = 0), adjunctive (n = 1) DC |
| CAS (symptomatic) | 117 | 0 | NA |
| CAS (asymptomatic) | 36 | 0 | NA |
| Endovascular treatment of vasospasm related to SAH | 209 | 0 | NA |
| Cerebral venous sinus procedures | 18 | 0 | NA |
| Dural arteriovenous fistula | 9 | 0 | NA |
| Tumor embolization (intracranial) | 21 | 0 | NA |
Note:—CAS indicates carotid angioplasty and stent placement; DC, decompression craniectomy with hematoma evacuation; NA, not applicable.
