Variant of internal jugular vein reconstruction in bilateral radical neck dissection.

BACKGROUND

The internal jugular vein (IJV) plays a major role in collecting venous blood from the cranium, face, and neck. Preserving or reconstructing at least one IJV during bilateral radical neck dissection (RND) allows preventing severe complications. The aim of this report was to present a variant of IJV reconstruction in bilateral radical neck dissection.

CASE SUMMARY: A 55-year-old male complained for a gingival mass for about 2 months, which was approximately 4 × 2 cm in size with a surface ulceration, located in the anterior mandibular area. There were bilateral cervical adenopathy. The computed tomography (CT) scan revealed mandibular bone destruction with surrounding soft tissue masse, multiple enlarged lymph nodes around bilateral submandibular space and bilateral carotid sheath, with obvious necrosis in the center. The preoperative diagnosis was mandibular gingiva squamous cell carcinoma (SCC), staged T4aN2bM0. Under general anesthesia, the patient underwent bilateral RND with sacrifice of right IJV and reconstruction of left IJV by anastomosis of IJV to the ipsilateral EJV using the common facial vein as a communicating way, followed by an expanded resection of mandibular gingiva SCC via marginal mandibulectomy, left anterolateral thigh (ALT) free flap reconstruction of the resulting defects, and tracheotomy. The patient's post-operative course was uneventfully.

CONCLUSION

In our case report, the immediate IJV reconstruction by the W method was performed without compromising oncologic principles and was found feasible, safe and effective to prevent the occurrence of severe postoperative complications related to bilateral RND with sacrifice of both IJV.
