  • Rupture of isolated Inferior Thyroid Artery aneurysm leading to life-threatening hemothorax
    Turkish Journal of Thoracic and Cardiovascular Surgery, 2013
    Co-Authors: Gökhan Lafçı
    Abstract:

    Tiroservikal dalin gercek anevrizmalari nadiren gorulur. Bu anevrizmalarin bazilari semptomsuz iken, digerlerinde nefes darligi, ses kisikligi ve yutma guclugu belirtileri eslik edebilir. Bu yazida yasami tehdit eden hemotoraksa neden olan izole Inferior tiroid arterinin spontan rupturu ve basarili cerrahi yaklasimi sunuldu. Anah tar soz cuk ler: Hemotoraks; inferiyor tiroid arter anevrizmasi; tiroservikal dal. The true aneurysms of thyrocervical trunk are rarely seen. Some of these aneurysms are asymptomatic, while others may present with dyspnea, hoarseness and dysphagia. In this report, we present a spontaneous rupture of isolated Inferior Thyroid Artery aneurysm leading to lifethreatening hemothorax and successfully treated with surgical approach.

  • Thyroid blood flow in Inferior Thyroid Artery as predictor for increase in levothyroxine dosage during pregnancy in women with Hashimoto's Thyroiditis - a retrospective study
    BMC pregnancy and childbirth, 2019
    Co-Authors: Masafumi Kurajoh, Akiyo Yamasaki, Toshiki Nagasaki, Yuki Nagata, Shinsuke Yamada, Yasuo Imanishi, Masanori Emoto, K. Takahashi, Kouji Yamamoto, Ayumi Shintani
    Abstract:

    We examined whether Inferior Thyroid Artery peak systolic velocity (ITA-PSV) predicts an increase in levothyroxine (LT4) dosage in pregnant women with Hashimoto’s Thyroiditis. Twenty-two women with Hashimoto’s Thyroiditis who were planning and later achieved pregnancy or confirmed as pregnant were enrolled in this retrospective longitudinal observational study. ITA-PSV and Thyroid volume were measured using ultrasonography. Serum concentrations of free thyroxine (F-T4), free triiodothyronine (F-T3), and Thyroid stimulating hormone (TSH) were simultaneously determined. We adjusted LT4 dosage to maintain serum TSH at

ITA-PSV and Thyroid volume were measured using ultrasonography. Serum concentrations of free thyroxine (F-T4), free triiodothyronine (F-T3), and Thyroid stimulating hormone (TSH) were simultaneously determined. We adjusted LT4 dosage to maintain serum TSH at < 2.5 μIU/mL (1st trimester) and later at < 3 μIU/mL (2nd, 3rd trimester). Eighteen patients (81.8%) required an increase in LT4 dosage during pregnancy, of whom 7 (31.8%) required an increase ≥50 μg. Multivariable regression analysis showed that TSH (β = 0.507, p = 0.008) and ITA-PSV (β = − 0.362, p = 0.047), but not Thyroid volume, F-T4, or F-T3, were independently associated with increased LT4 dosage. Receiver-operating characteristic analysis for predicting an increase in LT4 ≥ 50 μg/day showed that the area under the curve (0.905) for ITA-PSV with TSH was not significantly increased (p = 0.123) as compared to that (0.743) for TSH alone, whereas integrated discrimination improvement was significantly increased (27.9%, p = 0.009). In pregnant patients with Hashimoto’s Thyroiditis, ITA-PSV was a significant predictor of increase in LT4 dosage independent of TSH level, while ITA-PSV plus TSH showed significantly improved predictability as compared to TSH alone. These results suggest that ITA-PSV reflects residual Thyroid function and is useful for evaluating the need for increased Thyroid hormone production in pregnant patients with Hashimoto’s Thyroiditis.

  • The significance of Thyroid blood flow at the Inferior Thyroid Artery as a predictor for early Graves’ disease relapse
    Clinical endocrinology, 2005
    Co-Authors: Misako Ueda, Toshiki Nagasaki, Masaaki Inaba, Yasuro Kumeda, Yoshikazu Hiura, Hideki Tahara, Naoyoshi Onoda, Tetsuro Ishikawa, Yoshiki Nishizawa
    Abstract:

    Summary Objective  We investigated the clinical usefulness of Thyroid blood-flow measurement in predicting relapse of Graves’ disease (GD) in comparison with known risk factors for GD relapse. Measurement  Thyroid blood flow was measured in pulsed Doppler mode at the Inferior Thyroid Artery (ITA), and the peak systolic velocity (PSV) calculated. Patients  ITA-PSV was measured in euThyroid GD patients (n = 79) immediately before withdrawal of anti-Thyroid drug (ATD) and in healthy subjects (n = 17). Results  In the 79 euThyroid GD patients, the values of free triiodothyronine (FT3), TSH receptor autoantibody (TRAb), ITA-PSV and Thyroid volume were significantly higher in the relapse group (n = 40) than in the nonrelapse group (n = 39) and the Youden index of ITA-PSV was significantly higher than that of FT3, TSH, TRAb and vascular endothelial growth factor (VEGF). Conclusion  ITA-PSV may assist in the prediction of early GD relapse after ATD withdrawal.

  • Ruptured aneurysm of the Inferior Thyroid Artery: Repair with coil embolization
    Journal of vascular surgery, 2005
    Co-Authors: H. Edward Garrett, Robert W. Heidepriem, L. Paul Broadbent
    Abstract:

    Although pseudoaneurysm of the thyrocervical trunk is seen with increasing frequency as a result of trauma or central venous cannulation, true aneurysm of the thyrocervical trunk is exceedingly rare. A 44-year-old woman presented with acute left neck swelling that progressed rapidly to respiratory distress and subsequent hemothorax. Emergency endotracheal intubation was performed for airway control, and tube thoracostomy was placed for drainage of the pleural space. A review of the literature reveals that this is the second patient known to be successfully treated by arterial embolization of a ruptured aneurysm of the Inferior Thyroid Artery and the fifteenth known case of aneurysm of the Inferior Thyroid Artery. Surgical or endovascular intervention has been successful. Observation has been uniformly fatal. Because life-threatening rupture is possible, the presence of this aneurysm mandates intervention. Endovascular coil embolization is a viable option for treatment of this entity.
