Match each patient's clinical presentation and findings with the most appropriate definitive neurosurgical or endovascular intervention.

  • A 35-year-old man with severe traumatic brain injury has an intracranial pressure persistently above 30 mmHg despite sedation, hyperosmolar therapy, and cerebrospinal fluid drainage.Decompressive craniectomy
  • A 50-year-old woman treated for a ruptured cerebral aneurysm develops new right-sided hemiparesis on day 7. CT angiography confirms severe localized narrowing of the left middle cerebral artery.Endovascular intra-arterial vasodilator therapy
  • A 65-year-old man on warfarin develops progressive quadriparesis and hyperreflexia over 12 hours. MRI demonstrates a large, hyperacute dorsal fluid collection compressing the cervical spinal cord.Emergent cervical laminectomy and hematoma evacuation
  • A 42-year-old man presents with sudden bilateral lower extremity weakness, saddle anesthesia, and urinary retention. MRI reveals a massive central disc herniation at L4-L5.Emergent lumbar laminectomy and discectomy

Cevap

Refractory elevated intracranial pressure requires decompressive craniectomy. Symptomatic severe vasospasm is treated with intra-arterial vasodilators. A cervical epidural hematoma necessitates emergent cervical laminectomy and evacuation. Cauda equina syndrome requires emergent lumbar laminectomy and discectomy.
Each clinical scenario describes a distinct neurosurgical emergency with a specific, time-sensitive definitive intervention. Refractory intracranial hypertension requires decompressive craniectomy to increase cranial vault volume. Delayed cerebral ischemia from vasospasm requires endovascular vasodilators to restore perfusion. Compressive spinal lesions, such as an acute epidural hematoma or massive lumbar disc herniation, require emergent surgical decompression appropriate to their specific spinal level to prevent permanent tissue infarction.

Adım Adım Çözüm

1
Evaluate the trauma patient with refractory elevated intracranial pressure.
Identify decompressive craniectomy as the next step.
Maximal medical therapies have failed, leaving surgical decompression as the definitive intervention to relieve pressure.
2
Assess the post-subarachnoid hemorrhage patient with delayed focal deficits.
Identify endovascular intra-arterial vasodilator therapy as the correct intervention.
The timing and imaging are diagnostic for severe vasospasm, which requires endovascular rescue when symptomatic and anatomically localized.
3
Analyze the anticoagulated patient presenting with acute myelopathy and a dorsal fluid collection.
Identify emergent cervical laminectomy and hematoma evacuation.
The findings indicate a spinal epidural hematoma causing critical cord compression, a surgical emergency requiring prompt evacuation.
4
Evaluate the patient with saddle anesthesia, urinary retention, and bilateral leg weakness.
Identify emergent lumbar laminectomy and discectomy.
These are classic signs of cauda equina syndrome due to a massive lumbar disc herniation, requiring immediate surgical decompression of the nerve roots.
