Summary
Intraprocedural aneurysm rupture during endovascular coiling, often in small aneurysms, leads to significant mortality and new neurological deficits. Long-term outcomes show stable occlusion in most survivors.
Area of Science:
- Neurosurgery
- Interventional Radiology
- Vascular Neurology
Background:
- Intraprocedural aneurysm rupture is a critical complication of endovascular treatment for cerebral aneurysms.
- This complication is associated with substantial patient mortality.
Purpose of the Study:
- To evaluate the clinical outcomes of cerebral aneurysms that experienced rupture during endovascular coiling.
- To analyze the incidence and consequences of intraprocedural rupture during aneurysm embolization.
Main Methods:
- A retrospective review of 559 endovascular embolizations performed over six years.
- Analysis of 14 cases with intraprocedural aneurysm rupture, including acute and follow-up angiographic results.
- Assessment of clinical outcomes using the modified Rankin Scale.
Main Results:
- Aneurysm rupture during coiling occurred significantly more often in ruptured versus unruptured aneurysms.
- The complication resulted in a 21.4% mortality rate and a 21.4% rate of new neurological deficits.
- Acute embolization achieved complete occlusion in 57.1% of cases; long-term follow-up showed stable occlusion in 81.8% of survivors.
Conclusions:
- Intraprocedural rupture during endovascular coiling frequently involves small cerebral aneurysms.
- This complication is linked to a high mortality rate and potential for neurological deficits.

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...
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...

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...
