Summary
Radiofrequency ablation for thyroid nodules can rarely cause pseudoaneurysm. This case demonstrates successful treatment of a post-procedural pseudoaneurysm using ultrasound-guided thrombin injection, ensuring patient recovery.
Area of Science:
- Interventional Radiology
- Endocrinology
- Vascular Surgery
Background:
- Radiofrequency ablation (RFA) is a common treatment for benign thyroid nodules.
- Complications, though rare, can occur following RFA procedures.
- Neck swelling and tenderness post-RFA may indicate serious vascular issues.
Observation:
- A patient developed neck swelling and tenderness hours after RFA for thyroid nodules.
- Doppler ultrasound revealed a hematoma with a vascular mass, suspicious for pseudoaneurysm at the RFA site.
Findings:
- Fluoroscopy confirmed a pseudoaneurysm with contrast extravasation.
- Ultrasound-guided thrombin injection successfully occluded the pseudoaneurysm.
Implications:
- This case demonstrates the efficacy of US-guided thrombin injection for managing post-RFA pseudoaneurysms.
- Prompt diagnosis and intervention are crucial for favorable outcomes in managing rare RFA complications.

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...

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...

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...
