Insights

Dual antiplatelet therapy (DAPT) with aspirin and prasugrel may increase hemorrhage risk in neurointerventional surgery compared to aspirin and clopidogrel. This finding is crucial for patient safety and treatment selection in these procedures.

Area of Science:

  • Neurosurgery
  • Cardiology
  • Pharmacology

Background:

  • Dual antiplatelet therapy (DAPT) with aspirin and a thienopyridine is standard for preventing thromboembolic events in neurointerventional surgery.
  • Clopidogrel resistance is common, leading to interest in alternative agents like prasugrel.
  • Limited data exist on prasugrel's safety and efficacy in neurointerventional procedures.

Observation:

  • A retrospective review of 76 patients undergoing neurointerventional surgery was conducted.
  • Patients received either aspirin/clopidogrel or aspirin/prasugrel DAPT.
  • Patients on aspirin/prasugrel were pre-identified clopidogrel non-responders.

Findings:

  • Hemorrhagic complications occurred in 19.4% of patients on aspirin/prasugrel versus 3.6% on aspirin/clopidogrel (p=0.02).
  • No significant differences in thrombotic complications were observed between the groups.
  • Hemorrhage rates per procedure type were similar between treatment groups.

Implications:

  • Aspirin/prasugrel DAPT may be associated with an increased risk of hemorrhage in neurointerventional surgery.
  • These findings necessitate careful consideration of DAPT regimens in patients undergoing these procedures.
  • Further research is warranted to optimize antiplatelet strategies in neurointerventional surgery.

Venous Thrombosis III: Interprofessional Care

Venous thrombosis requires effective prevention and treatment strategies to improve patient outcomes and reduce potential complications.Prevention StrategiesHealthcare providers must prioritize preventing venous thromboembolism (VTE) for all adult patients upon admission. Interventions depend on bleeding and thrombosis risk, medical history, current medications, diagnoses, planned procedures, and patient preferences. Patients on bed rest should change positions every two hours and, if not...

Hemorrhagic Stroke ll: Pathophysiology

A hemorrhagic stroke develops when a cerebral blood vessel ruptures, allowing blood to escape into the surrounding brain tissue, as in intracerebral hemorrhage (ICH), or into the subarachnoid space, as in subarachnoid hemorrhage (SAH). Because the skull is a rigid compartment, the sudden presence of extravascular blood rapidly increases intracranial pressure and compresses adjacent neural structures, leading to immediate tissue injury and impaired cerebral perfusion.Mass Effect and Primary...

Aneurysm IV: Nursing Management

Vigilant monitoring for aneurysm rupture is essential for patients undergoing aortic surgery.Preoperative Nursing ManagementContinuously monitor the patient for manifestations of aneurysm rupture, such as pallor, weakness, tachycardia, hypotension, abdominal, back, groin, or periumbilical pain, changes in consciousness, and a pulsating abdominal mass. Regularly assess the patient's peripheral pulses.Instruct the patient to consume a clear liquid diet the day before surgery and administer...
Hemorrhagic Stroke l: Introduction01:17

Hemorrhagic Stroke l: Introduction

A hemorrhagic stroke is an acute neurological event that occurs when a weakened cerebral blood vessel ruptures, allowing blood to accumulate within or around the brain. The sudden release of blood forms a focal hematoma that increases intracranial pressure, displaces neural tissue, and can obstruct cerebrospinal fluid pathways. These effects may be compounded by intraventricular extension of the hemorrhage, cerebral edema, or compression of adjacent structures, all of which contribute to...

Pulmonary Embolism II: Diagnostic Studies and Interprofessional Care

Diagnosing Pulmonary EmbolismDiagnosing pulmonary embolism (PE) involves clinical assessment and advanced imaging tests. The preferred diagnostic tool is the spiral (helical) CT scan or CT angiography (CTA), which uses intravenous contrast media to visualize the pulmonary vasculature and identify emboli.A ventilation-perfusion (V/Q) scan is an alternative for patients unable to receive contrast media. This scan includes both perfusion and ventilation scanning. Perfusion scanning involves...
Vascular Spasm01:16

Vascular Spasm

The vascular phase, also known as vasospasm, is the initial stage of hemostasis, crucial for preventing excessive bleeding when a blood vessel is injured. After a vessel is cut, nerves in the damaged area trigger pain and other sensory impulses. Simultaneously, the smooth muscles in the vessel wall contract, resulting in a vascular spasm. This contraction reduces the vessel's diameter at the injury site, slowing or stopping blood loss through the vessel wall. Vascular spasms typically last for...
