“…SVS complexity seems to increase in accordance with the variability in the structure of the thyroid veins. The bilateral superior, middle, and inferior thyroid veins have been depicted in the literature as typical scenarios (8,9); however, multidetector-row CT scans have revealed variations in the structure of the thyroid veins (18). Several patterns of inferior veins featuring different numbers and joining sites to the brachiocephalic vein have been observed and the middle veins are frequently absent.…”

“…First, the superior and middle thyroid veins and the sites at which these veins joined the internal jugular veins were identified. Second, the inferior veins and the sites at which they joined the brachiocephalic veins were identified using transverse and coronal images in accordance with a previous study reporting the various branching patterns of inferior veins (18).…”

BackgroundSelective venous sampling (SVS) is an invasive localization study for persistent or recurrent hyperparathyroidism.PurposeTo assess the role of SVS in addition to non-invasive imaging for primary hyperparathyroidism (pHPT).Material and MethodsThis study was approved by the institutional review board and included 14 patients who underwent SVS and subsequent parathyroidectomy between January 2014 and April 2017 following a clinical diagnosis of pHPT. All patients underwent pre-SVS non-invasive imaging, including ultrasound, computed tomography (CT), and 99mTc-MIBI scintigraphy, and sensitivity was assessed using the operative and pathological findings.ResultsIn all but one case, a single parathyroid adenoma was responsible for the pHPT; the remaining case exhibited a chemical response following surgical removal of parathyroid tissue. The sensitivity (%) for ultrasound, CT, 99mTc-MIBI scintigraphy, and SVS was 76.9, 84.6, 69.2, and 76.9, respectively. SVS yielded positive results in four patients with discordant results and one patient with non-detectable results on imaging. In seven patients, a significant increase in the intact parathyroid hormone level was recognized only in the thyroid veins. The procedure time was in the range of 52–183 min (median = 89.5 min).ConclusionThe addition of SVS to a non-invasive imaging study would be helpful to locate the responsible lesion of pHPT with discordant or non-detectable results on imaging for initial surgical treatment as well.

“…Las venas tiroideas superiores e inferiores son constantes, pudiendo éstas presentar de todos modos variaciones en cuanto al lugar de emergencia en la superficie del lóbulo tiroido, su número y forma de terminación, en cuanto su desembocadura de manera aislada o formando troncos a través de la anastomosis con otras venas (Krausen, 1976;Wafae et al, 2008 Tomita et al (2015), en un estudio en base a hallazgos tomográficos en 80 pacienntes, encontraron la VTM presente en el 49 % del lado derecho y en el 36 % del lado izquierdo. Al igual que nuestro informe, encuentran mayor prevalencia del lado derecho de la glándula tiroides.…”

RESUMEN: El estudio de las venas tiroideas no ha recibido una investigación tan exhaustiva como lo tuvieron las arterias tiroideas y los nervios laríngeos en relación a la cirugía tiroidea.De los tres pedículos venosos de la glándula tiroides, el medio, de lejos es el menos estudiado. La vena tiroidea media es inconstante y es el primer elemento vascular de la glándula tiroides que debe ser seccionado antes de luxar el lóbulo hacia medial para evaluar sus relaciones posteriores. Su lesión puede provocar sangrado intraoperatorio dificultando secundariamente la identificación del nervio laríngeo inferior y las glándulas paratiroides, próximas a la misma. Se realizó un estudio descriptivo de corte transversal evaluando la pesencia, número, simetría y asociación de la vena tiroidea media con variables tales como edad y sexo del paciente, así como la hiperfuncionalidad de la glándula tiroides y la presencia del tubérculo de Zuckerkandl en 100 tiroidectomías totales llevadas a cabo en el Instituto Nacional del Cáncer y en el Servicio de Otorrinolaringología del Hospital Central del Instituto de Previsión Social del Paraguay. La prevalencia global de vena tiroidea media fue del 74 %. En el lóbulo derecho, la vena se presentó en el 60 %, mientras que en el lóbulo izquierdo en el 53 %. En el 38 % se encontró la vena en ambos lóbulos. En 4 pacientes se localizaron venas tiroideas medias dobles, en una de ellas fue bilateral. El mayor porcentaje de las venas tiroideas medias se originó en el tercio medio del lóbulo, el 72 % en el lado derecho y el 70% en el izquierdo. No se encontró asociación entre la presencia de la vena tiroidea media y la edad, sexo, estado de hiperfunción glandular, así como tampoco con la presencia del tubérculo de Zuckerkandl.

“…The right inferior thyroid vein usually runs along the front surface of the trachea from the thyroid gland. A study using computed tomographic scanning from the neck to the chest of a subject showed 3 patterns by which the right inferior thyroid vein flowed: 27% of the studied veins flowed into the right IJV, 32% flowed into the innominate vein, and 41% flowed to the junction of the bilateral brachiocephalic veins [ 11 ]. Thus, a catheter can become malpositioned into the right inferior thyroid vein because there are openings in the right IJV or right brachiocephalic vein leading to the right inferior thyroid vein.…”

Malposition of Peripherally Inserted Central Catheter Into the Right Inferior Thyroid Vein: A Case Report

et al. 2018

Patient: Female, 58Final Diagnosis: Breast cancerSymptoms: NoneMedication: NoneClinical Procedure: Insertion of a peripherally inserted central catheter (PICC)Specialty: AnesthesiologyObjective:Unusual or unexpected effect of treatmentBackground:A peripherally inserted central catheter (PICC) causes few serious complications but can be malpositioned. To avoid malpositioning, ultrasound guidance is widely used. Here, we report the case of a patient who received a PICC that was inserted under ultrasound guidance, but the catheter tip accidentally entered the right inferior thyroid vein.Case Report:A 58-year-old woman was scheduled for reconstructive mammoplasty. After general anesthesia, a PICC was inserted via the right basilic vein. The PICC was inserted under guidance using a portable ultrasound machine with a high-frequency linear transducer. The tip of the guide wire and catheter were confirmed by ultrasound to be in the right subclavian vein, not in the right internal jugular vein, during insertion. However, the chest X-ray performed after the PICC insertion showed that the catheter had moved into the right inferior thyroid vein.Conclusions:Malpositioning of a PICC can occur into any small vein. Ultrasound should be used not only to avoid malpositioning into the IJV, but also to confirm the proper position of the catheter tip during PICC insertion.
