A Comparison of Two Operation Methods Revealed the Risk Factors and the Necessity of LN-prRLN Dissection in Papillary Thyroid Carcinoma: A Retrospective Cohort Study in FUSCC
Figure 2
Axial contrast-enhanced CT of LN-prRLN in the cervical space. Axial contrast-enhanced CT scan shows that the LN-prRLN (M) is medial-posterior to the level of the CCA and IJV and anterior to the prevertebral fascia (aside the tracheoesophageal sulcus). B. The surgical field after LN-prRLN dissection during right-sided central compartment dissection. The part within the quadrangle with solid lines presents the detailed anatomic structure of the LN-prRLNlevel. The right CCA, IJV, and SCM were retracted laterally with a long-arm retractor. CCA: common carotid artery; IJV: interjugular vein; SCM: sternocleidomastoid muscle; T: trachea; VA: vertebral artery; C7: 7th cervical vertebra; R: first rib; Eso: esophagus.
