Aneurysm III: Interprofessional Care

479
Aneurysm management involves either conservative medical therapy or surgical intervention, depending on the size and symptoms of the aneurysm. Conservative management is generally reserved for smaller, asymptomatic aneurysms, while larger or symptomatic aneurysms often necessitate surgical repair.Conservative Medical TherapyFor small, asymptomatic aneurysms, particularly abdominal aortic aneurysms (AAA) less than 5.5 centimeters in diameter, conservative medical therapy is recommended.

Venous Thrombosis III: Interprofessional Care

482
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...

Area of Science:

  • Neurosurgery
  • Vascular Neurology
  • Surgical Techniques

Background:

  • Basilar artery aneurysms (BAA) are rare but critical cerebrovascular lesions.
  • Ruptured BAAs carry a high risk of catastrophic neurological outcomes.
  • Low-lying BAAs present unique surgical challenges.

Purpose of the Study:

  • To present a case of a ruptured low-lying basilar tip aneurysm treated surgically.
  • To evaluate the efficacy of the Level 3 pretemporal transcavernous approach for BAA clipping.
  • To demonstrate the surgical technique in a clinical video presentation.

Main Methods:

  • A 60-year-old female patient with a ruptured low-lying basilar tip aneurysm (Hunt and Hess grade IV) was treated.
  • A frontotemporal craniotomy was performed, utilizing the Level 3 pretemporal transcavernous approach.
  • Surgical clipping of the basilar artery aneurysm was successfully achieved.

Main Results:

  • The patient experienced an uneventful recovery following the surgical intervention.
  • At 3-month follow-up, the patient was functionally independent.
  • The Level 3 pretemporal transcavernous approach proved effective for clipping the low-lying BAA.

Conclusions:

  • The Level 3 pretemporal transcavernous approach is a valuable and effective surgical option for low-lying basilar tip aneurysms.
  • This technique facilitates safe and successful clipping of challenging BAA.
  • Successful surgical management leads to favorable patient outcomes and functional recovery.
