Study of thyrocervical trunk in adult cadavers

Abstract               Aims and Objectives; Branches of Subclavian artery gain importance as it is closely associated with many neurovascular structures and it is involved in so many clinical instances. Thyrocervical trunk is one among its branches which gain importance.so the study of Thyrocervical Trunk including its mode of origin and its branching pattern were studied in forty Adult cadavers. Materials and Methods: In Forty adult cadavers of unknown sex subclavian artery was exposed using conventional dissection method. Origin and the branching pattern of Thyrocervical trunk was studied. Results and Conclusion; In all the specimens Thyrocervical trunk arose from First part of Subclavian artery. The number of branches varied from one to four, in both sides in adult. In all the specimens branches of Thyrocervical trunk passes in front of Scalenus Anterior muscle. As so many neurovascular structures are closely related to thyrocervical trunk and its •branches this study will be useful clinically both for diagnostic and treatment purposes
