HIFU in Patients With Non-malignant Thyroid Nodules
HIFU in Patients With Non-malignant Thyroid Nodules
Use of a high intensity focused ultrasound (HIFU) in patients with non-malignant thyroid
 nodules.
Inclusion Criteria:

 -  Male or female patient 18 years or older.

 -  Patient presenting with at least one thyroid nodule with no signs of malignancy:

 1. Non suspect clinically and at ultrasonography imaging

 2. Benign cytological diagnosis at fine-needle aspiration biopsy (FNAB) from the
 last 6 months

 3. Normal serum calcitonin

 4. No history of neck irradiation

 -  Normal thyroid-stimulating hormone (TSH).

 -  Targeted nodule accessible and eligible to HIFU

 -  Absence of abnormal vocal cord mobility at laryngoscopy.

 -  Nodule diameter ≥ 10mm measured by ultrasound.

 -  Nodule volume inferior to 10 cc

 -  Composition of the targeted nodule(s) : no more than 30% cystic

 Exclusion Criteria:

 -  Head and/or neck disease that prevents hyperextension of neck.

 -  Known history of thyroid cancer or other neoplasias in the neck region.

 -  History of neck irradiation.

 -  Macrocalcification inducing a shadow in the thyroid significant enough to preclude the
 HIFU treatment

 -  Posterior position of the nodule if the thickness of the nodule is <15mm

 -  Pregnant or lactating woman

 -  Any contraindication to the assigned analgesia/anaesthesia.
