Summary
Persistent sciatic artery aneurysms (PSAA) can cause severe limb issues. Endovascular stent grafting offers a less invasive, successful treatment option for these rare vascular anomalies, avoiding high-morbidity open surgery.
Area of Science:
- Vascular Surgery
- Endovascular Techniques
- Anatomical Variations
Background:
- Persistent sciatic artery (PSA) is a rare fetal circulatory remnant, present in <0.1% of individuals.
- PSA aneurysms (PSAA) develop in up to 60% of patients with PSA.
- PSAA can lead to debilitating symptoms like neuropathy, claudication, and limb ischemia.
Observation:
- Historical treatment for PSAA involved open surgery with interposition grafting, associated with significant morbidity.
- This study presents a case of a large, symptomatic PSAA.
- Successful management was achieved using endovascular stent grafting.
Findings:
- Endovascular stent grafting provided a successful treatment for a large, symptomatic PSAA.
- Intermediate-term follow-up demonstrated the efficacy of this minimally invasive approach.
- This method avoids the high risks associated with traditional open surgical repair.
Implications:
- Endovascular stent grafting is a viable and less morbid alternative for managing PSAA.
- This technique expands treatment options for rare vascular anomalies.
- Minimally invasive approaches can improve outcomes for patients with PSAA.

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...

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...

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...

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...
