Summary
Persistent sciatic artery (PSA) aneurysm can cause recurrent leg embolism. This case highlights successful thrombectomy and bypass surgery despite challenging anatomy, offering insights into managing this rare vascular anomaly.
Area of Science:
- Vascular Surgery
- Congenital Vascular Anomalies
Background:
- Persistent sciatic artery (PSA) is a rare congenital vascular anomaly.
- PSA aneurysms can lead to severe complications like leg ischemia and recurrent embolism.
- Management requires revascularization and recurrence prevention.
Purpose of the Study:
- To describe a challenging case of PSA aneurysm with recurrent embolism.
- To detail the surgical management involving thrombectomy and bypass surgery.
- To discuss the implications for treating this rare condition.
Main Methods:
- A 76-year-old woman with recurrent leg embolism from PSA aneurysm.
- Surgical intervention included thrombectomy of the posterior-tibial artery (PTA) and femoral-PTA bypass.
- Ligation of the proximal PTA was performed to prevent recurrence.
Main Results:
- The surgical procedure was successful despite difficult anatomical variations.
- No complications or recurrence of embolism were observed one year post-surgery.
- The residual PSA aneurysm remains untreated without current clinical issues.
Conclusions:
- Persistent sciatic artery (PSA) is a critical consideration in cases of acute limb ischemia.
- Treatment strategies for PSA should be tailored to individual clinical symptoms and anatomical conditions.
- Surgical intervention, including thrombectomy and bypass, can be effective even in complex PSA cases.

Pulmonary embolism (PE) occurs when a thrombus, fat or air embolus, amniotic fluid, or tumor tissue blocks one or more pulmonary arteries. These blockages originate in the venous system or the right side of the heart.EtiologyPE primarily arises from deep vein thrombosis (DVT) and other hypercoagulable states, such as inherited thrombophilias. Additional etiological factors include venous stasis, commonly seen in obesity, and endothelial injury from surgery and trauma. Less common causes include...

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...

A pulmonary embolism occurs when a thrombus, amniotic fluid, tumor tissue, fat, or air embolus blocks one or more pulmonary arteries. Effective nursing management and patient education are crucial for improving outcomes and preventing recurrence.Nursing management starts with obtaining a comprehensive patient history, particularly noting any history of deep vein thrombosis (DVT). Assess for clinical manifestations, including dyspnea, chest pain, crackles, heart murmurs, and signs of right-sided...

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...

Diagnosing Pulmonary EmbolismDiagnosing pulmonary embolism (PE) involves clinical assessment and advanced imaging tests. The preferred diagnostic tool is the spiral (helical) CT scan or CT angiography (CTA), which uses intravenous contrast media to visualize the pulmonary vasculature and identify emboli.A ventilation-perfusion (V/Q) scan is an alternative for patients unable to receive contrast media. This scan includes both perfusion and ventilation scanning. Perfusion scanning involves...
