Summary
Persistent sciatic artery aneurysm (PSAA) in a 66-year-old woman was successfully treated with bypass surgery and exclusion. Long-term outcomes for symptomatic PSAA and lower limb ischemia are generally satisfactory.
Area of Science:
- Vascular Surgery
- Congenital Vascular Malformations
- Medical Case Reports
Background:
- Persistent sciatic artery (PSA) is a rare congenital vascular anomaly.
- Symptomatic PSA can lead to critical lower limb ischemia and aneurysmal degeneration.
Observation:
- A 66-year-old woman presented with a buttock mass and bilateral lower limb ischemia.
- Preoperative imaging revealed a thrombosed left PSA aneurysm (PSAA) with extensive arterial occlusions.
Findings:
- Successful surgical treatment involving bypass grafting and PSAA exclusion.
- Postoperative imaging confirmed graft patency and excluded PSAA thrombosis.
- Literature review of 45 articles (67 limbs) indicated satisfactory intermediate/long-term outcomes for symptomatic PSAA treatment.
Implications:
- Surgical intervention offers a viable and effective treatment for symptomatic PSA and associated lower limb ischemia.
- Timely management of PSAA can prevent severe ischemic complications and improve patient prognosis.
- Further research into optimal surgical techniques and long-term surveillance is warranted.

01:27Peripheral Artery Disease III: Interprofessional Care
Peripheral Artery Disease (PAD) is characterized by narrowed arteries that diminish blood flow to the extremities. Effective management of PAD requires an interprofessional approach involving various healthcare professionals. The critical aspects of interprofessional care for PAD patients focus on risk factor modification, drug therapy, exercise therapy, nutrition therapy, critical limb ischemia care, and interventional radiology and surgical procedures.The primary treatment goal for PAD...
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...
01:26Varicose Veins II: Diagnostic Studies and Interprofessional Care
Varicose veins, or varicosities, develop when the valves in the veins, which control blood flow, weaken or damage. It causes blood to pool and the veins to enlarge. Understanding the clinical manifestations, diagnostic approaches, and management options for varicose veins is crucial for effective treatment and relief.Clinical manifestationsClinical manifestations of varicose veins include a heavy, achy feeling or pain after prolonged standing or sitting. This discomfort can often be relieved by...

During the postoperative period, it is crucial to focus on maintaining circulation, identifying and managing potential complications, and planning for discharge.Nursing AssessmentVital signs monitoring: Regularly monitor vital signs, including blood pressure, heart rate, respiratory rate, and temperature, to detect early signs of complications such as bleeding and infection.Circulation assessment: Monitor pulses, perform Doppler assessments, and check capillary refill, color, temperature, and...
01:21Peripheral Arterial Disease II: Clinical Manifestations and Diagnostic Evaluation
Clinical manifestationsPeripheral Arterial Disease (PAD) manifests through a range of symptoms, from the characteristic intermittent claudication to atypical presentations and severe complications in advanced stages. Intermittent claudication, a hallmark symptom of PAD, presents as exercise-induced muscle pain that typically resolves within minutes of rest. This pain is reproducible and stems from inadequate blood flow, leading to the accumulation of lactic acid produced during anaerobic...
