Background: The end-diastolic velocity (EDV) of thyroid arteries reflects peripheral blood flow resistance.
Objective: The aim was to evaluate EDV correlations with other Doppler sonography parameters and with clinical and biochemical variables in a sample of patients with hypothyroidism caused by chronic autoimmune thyroiditis (CAT).
Methods: A sample of 48 CAT hypothyroid patients receiving treatment with stable doses of levothyroxine was selected. The participants underwent clinical evaluation and measurement of serum thyrotropin (TSH), total triiodothyronine (T3), total thyroxine (T4), free T4, thyroid peroxidase antibodies (anti-TPO), and antithyroglobulin antibodies (anti-Tg) and Doppler sonography.
Results: The EDV of the inferior thyroid arteries (ITA-EDV) was strongly and positively correlated with the peak systolic velocity of the inferior thyroid arteries (ITA-PSV, = 0.919), thyroid volume ( = 0.711), and thyroid visual vascularization pattern (TVP, = 0.687). There was no correlation between ITA-EDV and the clinical variables, hormones, anti-TPO, or anti-Tg.
Conclusion: The strong correlation of ITA-EDV with ITA-PSV, TVP, and volume suggests that increased vascularization in CAT may be associated with a reduction in thyroid blood flow resistance, possibly due to an angiogenesis-induced increase in the total vascular cross-sectional area of the parenchyma.

Atherosclerosis (AS) is a chronic vascular disease characterized by inflammation of the arterial wall and the formation of cholesterol plaques. Hashimoto's thyroiditis (HT) is an autoimmune disorder marked by chronic inflammation and destruction of thyroid tissue. Although previous studies have identified common risk factors between AS and HT, the specific etiology and pathogenic mechanisms underlying these associations remain unclear.

Background And Purpose: Radiation-induced hypothyroidism (RIHT) is a late complication of intensity-modulated radiation therapy (IMRT) for nasopharyngeal carcinoma (NPC). We evaluated thyroid protection in NPC patients receiving IMRT using modified delineation (MD) of cervical lymphatic drainage areas, sparing the common carotid artery within the clinical target volume (CTV), to assess its impact on thyroid function and survival outcomes.
Materials And Methods: This retrospective cohort study included patients without metastatic lymph nodes at levels III and IV who received neck irradiation.

Mediastinal mass syndrome represents a major threat to respiratory and cardiovascular integrity, with difficult evidence-based risk stratification for interdisciplinary management. We conducted a narrative review concerning risk stratification and difficult airway management of patients presenting with a large mediastinal mass. This is supplemented by a case report illustrating our individual approach for a patient presenting with a subtotal tracheal stenosis due to a large cyst of the thyroid gland.

In this report, a 37-year-old woman presented with a multi-nodular goitre with clinical features concerning for transient cerebral ischaemia. The anaesthetic management and neurological monitoring used to mitigate the risk of cerebral ischaemia during thyroidectomy is described and the literature surrounding this rare complication is explored.

Purpose: This study systematically evaluated the diagnostic performance of dual-energy computed tomography (DECT) quantitative parameters in detecting cervical lymph node metastasis in patients with papillary thyroid cancer (PTC).
Method: We searched PubMed, Embase, Web of Science, Cochrane Library, China National Knowledge Infrastructure, and Wanfang Data databases for relevant original studies from database inception to March 2024. The quality of the included studies was evaluated using the QUADAS-2 tool.
