Abstract
ObjectiveAortopexy including innominate artery suspension is a well-established treatment of anterior vascular compression and associated tracheomalacia. We report the results of our case series of cervical approach to innominate artery suspension and hypothesize that increased distance from the innominate to the sternum is predictive of superior symptomatic outcome. Study designRetrospective Case Series. MethodsAll cases of cervical innominate artery suspension at our institution over the last 10 years were reviewed. CT scans of the neck and chest were reviewed to obtain anatomical measurements including anterior-posterior thoracic outlet distance, thymic thickness, and sternum-innominate artery distance. Measurements were compared with surgical outcomes as verified by follow up bronchoscopy and clinical course to determine factors predictive of success. ResultsTen cases of cervical innominate artery suspension were performed by the otolaryngology service at our institution over the last 10 years. Six patients had improvement in their symptoms. The average sternum-innominate artery distance (SID) was larger (14.4 mm (95% CI 9.1–19.7)) in patients who had improvement in clinical symptoms following innominate suspension compared to those that did not improve (6.3 mm (95% CI 2.5–10.1)) (p value = 0.02). Similarly, the anterior-posterior distance of the thoracic outlet was larger (34.9 mm (95% CI 27.4–42.4)) in patients who had improvement post-op compared to those that did not improve (22.6 mm (95% CI 18.2–27.2) (p value = 0.01). Two patients required spine surgery to achieve improvement in their symptoms. ConclusionCervical innominate artery suspension is successful in carefully selected patients. More space in the thoracic outlet and larger distance from the innominate artery to the sternum is associated with symptomatic improvement.
