Summary
Endovascular coil embolization is a viable treatment for ruptured brain aneurysms with vasospasm, offering successful occlusion and vessel dilation. This approach may be a safe alternative to delayed surgery, reducing risks of re-rupture.
Area of Science:
- Neurosurgery
- Interventional Neurology
- Vascular Neurology
Background:
- Vasospasm following subarachnoid hemorrhage complicates ruptured aneurysm treatment.
- Delayed surgical clipping due to vasospasm increases risks of aneurysm re-rupture and poor patient outcomes.
Purpose of the Study:
- To evaluate the safety and efficacy of endovascular coil embolization in treating ruptured aneurysms complicated by vasospasm.
- To determine if endovascular coil embolization is a contraindication in cases of vasospasm.
Main Methods:
- Retrospective analysis of 11 consecutive patients with ruptured aneurysms and vasospasm treated with endovascular coil embolization.
- Procedures performed 2-17 days post-subarachnoid hemorrhage.
- Assessment of aneurysm occlusion, vasospasm resolution, technical complications, and clinical outcomes.
Main Results:
- Successful endovascular coil embolization achieved complete aneurysm occlusion and vasospasm resolution in 10 out of 11 patients.
- No aneurysmal re-rupture or major technical complications occurred during endovascular procedures.
- Cerebral infarction occurred in 4 patients, with only one case potentially related to catheterization; all neurological deficits resolved within 3 months.
Conclusions:
- Endovascular coil embolization is a safe and effective treatment option for ruptured aneurysms presenting with vasospasm.
- This technique avoids the risks associated with delayed surgical intervention.
- Further large-scale studies are warranted to confirm these preliminary findings.

01:22Aneurysm 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...
01:26Aneurysm 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...
01:16Vascular 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...
01:30Aneurysm I: Introduction
An aortic aneurysm is a localized outpouching or dilation at a weak point in the artery wall. It may involve different parts of the aorta, such as the abdominal aorta, aortic arch, or thoracic aorta.Etiological factorsSeveral disorders are associated with aortic aneurysms.Congenital causes, such as primary connective tissue disorders like Marfan syndrome, impact the integrity and strength of connective tissues, notably affecting the aorta. Marfan syndrome is a genetic disorder that specifically...
