Surgical technique and results of tracheal and carinal replacement with aortic allografts for salivary gland-type carcinoma.

Objective: We describe the surgical technique and peroperative management of tracheal and carinal replacement with aortic allografts for large salivary gland-type carcinoma and report the results with a mean 34 months' follow-up.

Methods: We performed tracheal and carinal replacements with aortic allografts in 6 patients with extensive mucoepidermoid (n = 1) or adenoid cystic (n = 5) carcinomas. Tracheal tumor resection was followed by carinal restitution (n = 3) and interposition of the graft, splinted by a silicone stent.

Coronary artery imaging during preoperative CT staging: preliminary experience with 64-slice multidetector CT in 99 consecutive patients.

The purpose of this study was to evaluate the clinical feasibility of coronary artery imaging during routine preoperative 64-slice MDCT scans of the chest. Ninety-nine consecutive patients in sinus rhythm underwent a biphasic multidetector-row spiral CT examination of the chest without the administration of beta-blockers, including an ECG-gated acquisition over the cardiac cavities, followed by a non-gated examination of the upper third of the thorax. Data were reconstructed to evaluate coronary arteries and to obtain presurgical staging of the underlying disease.
