Summary
Direct surgery effectively treated internal carotid artery bifurcation aneurysms in 18 patients. This pterional approach yielded excellent results with no mortality, highlighting a safe and effective surgical strategy.
Area of Science:
- Neurosurgery
- Vascular Neurology
Background:
- Internal carotid artery bifurcation aneurysms pose significant surgical challenges.
- Direct surgical intervention requires precise anatomical dissection and strategic approaches.
Observation:
- The pterional approach was consistently utilized for all 18 patients.
- Dissection strategy was tailored based on aneurysm size and intracranial internal carotid artery length.
- Specific techniques involved proximal-to-distal dissection for smaller aneurysms and sylvian fissure dissection for larger ones or longer parent arteries.
Findings:
- Clipping of 18 internal carotid artery bifurcation aneurysms was performed.
- Surgical outcomes included 16 excellent, 1 good, and 1 fair result.
- No mortality was recorded in the series.
Implications:
- The pterional approach with tailored dissection is a safe and effective method for treating internal carotid artery bifurcation aneurysms.
- This strategy contributes to favorable patient outcomes and minimizes surgical risk.
- Further research can explore long-term efficacy and comparative analyses with endovascular techniques.

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...

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...
