Microvascular reconstruction for head and neck cancers has improved both cosmesis and functionality of patients undergoing treatment. Many patients have had prior surgery (neck dissection), radiation and/or chemotherapy as part of their management. When microvascular reconstruction is required after previous treatment, finding appropriate vessels for anastomosis can be difficult. In this paper we explore the options for microvascular reconstruction in the vessel-depleted neck.
Arterial options that exist when the neck is depleted of vessels include the superficial temporal, transverse cervical, thoracoacromial, and the internal mammary artery. Venous options include the cephalic vein and vein grafts.
The external carotid artery and the internal jugular vein are the most commonly utilized vessels in microvascular reconstruction when available. However, prior chemotherapy and/or radiation can cause significant scarring and damage to these vessels. Also in patients who have had previous surgery, these vessels can be resected or altered in a way that they are deemed unusable. In these situations several vascular options exist outside the neck.
头颈部癌症的微血管重建改善了接受治疗患者的美观和功能。许多患者在其治疗过程中曾接受过先前的手术(颈部清扫术)、放疗和/或化疗。当先前治疗后需要微血管重建时,找到合适的血管进行吻合可能会很困难。在本文中,我们探讨了血管缺失颈部微血管重建的选择。
当颈部血管缺失时,可用的动脉选择包括颞浅动脉、颈横动脉、胸肩峰动脉和胸廓内动脉。静脉选择包括头静脉和静脉移植物。
当有条件时,颈外动脉和颈内静脉是微血管重建中最常用的血管。然而,先前的化疗和/或放疗可导致这些血管严重瘢痕形成和损伤。同样,在曾接受过先前手术的患者中,这些血管可能会被切除或以被认为无法使用的方式改变。在这些情况下,颈部以外存在几种血管选择。
