Carotid artery resection and replacement in patients with head and neck malignant tumors.

Tumor involvement of the carotid artery with head and neck cancers may be present either simultaneously with the primary lesion or more often appears at a later date following resection of the primary tumor. Management of the secondary tumor consists of its resection together with the involved carotid artery with or without carotid artery reconstruction. The Authors are convinced that the best chance for cure of patients with advanced head and neck squamous cell cancers involving the carotid artery is radical extirpation with ablative surgery in the form of en block resection of the primary lesion, the secondary tumor, and the involved carotid artery followed by immediate revascularization. This bold approach was carried out in two male patients, 48 and 61 years of age, followed by chemotherapy and radiation therapy in one and radiation therapy alone in the other, with excellent results. Dermal grafts were placed over the entire length of the arterialized veins to protect them from radiation injury. Based on this limited experience and excellent results, we recommend this one-stage surgical ablative procedure in well selected patients. However, cooperation between the ENT and vascular surgeons, strict adherence to the principles and techniques of vascular surgery, and coverage of the arterialized vein with a dermal graft is absolutely essential.

The upper arm AV hemoaccess: long term follow-up.

The technique of the upper arm fistula using the end of the transposed basilic vein to the side of the brachial artery is reviewed. The functional patency rate at eight years is 70 percent. Complications associated with this angioaccess are minimal and easily managed. Its advantages include: the ease of the techniques, utilization of the patient's own transposed autologous vein, maintaining venous anatomic continuity with the axillary vein, thus avoiding a veno-venous anastomosis and a long superficially located access with excellent flow and with long functional patency rate.
