A 24-Year-Old with a Neck Mass and Palpitations

Control thyrotoxicosis before surgery. Operating on an uncontrolled thyrotoxic patient risks thyroid storm-fever, tachyarrhythmia, delirium, high-output failure, and death-especially with the stress of anesthesia and surgery.

Preoperative regimen:

• Beta-blockade (e.g., propranolol 20–40 mg q6–8h, titrated to HR <90 and symptom control) for rapid symptom control; esmolol if IV needed.
• Thionamide (methimazole or PTU) to block hormone synthesis; takes 2–6 weeks to render euthyroid.
• Iodine (SSKI or Lugol's) added after thionamide is started, typically 7–10 days before surgery, to reduce gland vascularity and hormone release (Wolff-Chaikoff effect). Give iodine after, not before, thionamide to avoid fueling synthesis.
• Glucocorticoids (e.g., hydrocortisone) in severe disease or if storm risk is high, to block peripheral conversion.

Timing: Aim for a euthyroid state (normal T3/T4, HR controlled) before elective thyroidectomy. If surgery is urgent (e.g., airway compromise, suspected malignancy with rapid growth), proceed only with aggressive medical preparation and ICU availability.

Operative plan: For a Bethesda V nodule >1 cm with suspicious ultrasound features, diagnostic/therapeutic thyroidectomy is indicated. Options:

• Lobectomy (if the nodule is isolated and the contralateral lobe is normal) vs total thyroidectomy. Given Bethesda V (high but not definitive malignancy risk) and a 3.2 cm nodule, many would favor lobectomy with intraoperative decision or total thyroidectomy if malignancy is confirmed or the patient prefers definitive single-stage management. Total thyroidectomy allows radioiodine if needed but commits to lifelong replacement and parathyroid/recurrent laryngeal nerve risk.
• Central neck dissection is not routinely performed for Bethesda V without confirmed malignancy; if final pathology confirms papillary carcinoma, therapeutic central dissection is done for clinically involved nodes, prophylactic dissection is debated.
• Do not perform routine lateral neck dissection without proven nodal disease.

Thyrotoxic influence:

• Surgery should be deferred until euthyroid unless there is an urgent indication; this is an elective cancer operation in most cases.
• Antithyroid drugs should be continued through the perioperative period; beta-blockade maintained.
• Avoid iodine if it would worsen thyrotoxicosis unless the patient has been blocked with thionamide first.
• If she cannot be rendered euthyroid, consider radioactive iodine or lifelong antithyroid drugs as alternatives, but RAI is generally avoided in large nodules with suspicious features until malignancy is addressed.

Risks and mitigation:

1. Recurrent laryngeal nerve injury (unilateral ~1–2%, bilateral <1% in experienced hands): Identify the nerve routinely; consider intraoperative nerve monitoring; avoid ligating the inferior thyroid artery trunk; document pre- and postoperative voice assessment. Bilateral injury is an airway emergency requiring immediate re-exploration or tracheostomy.
2. Hypoparathyroidism (transient up to 20–30%, permanent ~1–2%): Preserve parathyroid glands with their vascular supply; autotransplant a devascularized gland into the sternocleidomastoid; check ionized calcium/PTH postoperatively and supplement calcium and calcitriol as needed.
3. Bleeding/hematoma (airway-threatening): Meticulous hemostasis; instruct the patient to return immediately for neck swelling or breathing difficulty; keep a suture removal kit and consider leaving a drain in selected cases.
4. Hypothyroidism: Lifelong levothyroxine; counsel explicitly.
5. Wound/seroma, hypertrophic scar: Closure technique and counseling.
6. Anesthesia/thyroid storm risk: Ensure euthyroid state preoperatively.

Counseling: Emphasize that surgeon volume and nerve monitoring matter; document the discussion of temporary vs permanent complications.
