Insights

Endovascular treatment for intracranial aneurysms is effective, with rupture occurring at smaller sizes. This study highlights key patient and aneurysm characteristics in a resource-limited setting.

Area of Science:

  • Neurosurgery
  • Interventional Neuroradiology
  • Vascular Neurology

Background:

  • Intracranial aneurysms pose a significant global mortality risk.
  • Endovascular management is a preferred treatment for select patients.
  • Patient demographics and aneurysm characteristics vary across populations.

Purpose of the Study:

  • To investigate the profile of patients with intracranial aneurysms undergoing endovascular treatment.
  • To analyze patient demographics, risk factors, indications, and aneurysm characteristics.
  • To assess intra-operative complications in a specific healthcare setting.

Main Methods:

  • Retrospective study over three years (January 2018 - January 2021).
  • Inclusion of all adult patients undergoing endovascular management.
  • Statistical analysis using the Chi-square test for categorical variables.

Main Results:

  • 77 patients included; mean age 47 ± 11.6 years; male-to-female ratio 1:1.8.
  • Hypertension was the most common risk factor (27%).
  • Ruptured aneurysms, small neck size (<4mm), and internal cerebral artery (ICA) locations showed statistical significance (p=0.020, p=0.010, p=0.001 respectively).

Conclusions:

  • Findings align with known female preponderance and anterior circulation aneurysm prevalence.
  • Endovascular management demonstrated a low complication rate.
  • Intracranial aneurysms were observed to rupture at smaller dimensions.

Aneurysm II: Clinical Manifestations and Diagnostic Studies

Thoracic, aortic arch and abdominal aneurysms are significant vascular conditions that can present with various clinical manifestations and lead to serious complications. Understanding these manifestations and the appropriate diagnostic studies is essential for effective management and treatment.Thoracic Aortic AneurysmsThoracic aortic aneurysms often remain asymptomatic until they reach a size that impinges on adjacent structures. They typically cause deep, diffuse chest pain that radiates to...

Aneurysm III: Interprofessional Care

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. This...

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...

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...
