Carotid Reconstruction with Bovine Carotid Heterograft after En Bloc Resection of Squamous Cell Carcinoma with Direct Internal Carotid Invasion.

We report a novel use of Artegraft (North Brunswick, NJ) bovine heterograft for carotid reconstruction after resection of a neck squamous cell carcinoma (SCC). A 65-year-old man presented with a large left neck SCC encasing and invading the cervical internal carotid artery (ICA). Computed tomography angiography revealed an incomplete Circle of Willis, and no viable vein conduit on duplex mapping. The patient underwent en bloc resection including portion of the cervical ICA followed by reconstruction with Artegraft which was well tolerated. This represents the first case report of tumor invasion of the ICA reconstructed using Artegraft as conduit.
