Insights

Endovascular treatment (EVT) for anterior choroidal artery aneurysms (AChAA) is effective, often requiring adjunctive techniques like balloon or stent-assisted coiling due to anatomical challenges. This study shows good clinical and long-term anatomical outcomes for AChAA EVT.

Area of Science:

  • Neurosurgery
  • Interventional Radiology
  • Vascular Neurology

Background:

  • Anterior choroidal artery aneurysms (AChAA) present treatment challenges due to their proximity to the parent artery.
  • Endovascular treatment (EVT) is a viable option for AChAA.

Purpose of the Study:

  • To report the experience and outcomes of endovascular treatment for anterior choroidal artery aneurysms.
  • To evaluate the safety and efficacy of EVT in managing AChAA.

Main Methods:

  • Retrospective review of prospectively maintained database for AChAA treated with embolization.
  • Analysis of clinical data, procedural details, and angiographic outcomes.

Main Results:

  • Eleven patients with AChAA treated between 2004-2008; 5 with subarachnoid hemorrhage, 6 asymptomatic.
  • Aneurysm sizes ranged from 2-13 mm, with 9 having unfavorable neck/sac ratios.
  • EVT techniques included balloon-assisted coiling (8), coiling (2), and stent-assisted coiling (1); no procedural complications, excellent outcomes in 10/11 patients.

Conclusions:

  • Endovascular treatment of AChAA yields favorable clinical and long-term anatomical results.
  • Adjunctive techniques like balloon or stent-assisted coiling are frequently necessary for AChAA EVT due to aneurysm characteristics.

Aneurysm III: Interprofessional Care01:26

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...
Open Angle Glaucoma: Treatment01:27

Open Angle Glaucoma: Treatment

In open-angle glaucoma, the iridocorneal angle remains open, but the trabecular meshwork becomes stiff, slowing down the outflow of aqueous humor. This causes a buildup of aqueous humor in the anterior chamber, leading to a sudden increase in intraocular pressure. The treatment for open-angle glaucoma focuses on reducing the elevated intraocular pressure by either decreasing the secretion of aqueous humor or increasing its outflow.
Drugs such as carbonic anhydrase inhibitors, α2- and...
