Abstract
ObjectiveTo investigate the feasibility and effect of retrograde thoracic duct approach via left venous angle in the treatment of chylothorax.
MethodsFrom July 2019 to April 2021, the clinical data of 16 patients with chylothorax in Shanghai Pulmonary Hospital Tongji University were retrospectively collected. All patients underwent percutaneous inguinal lymphography, super selective retrograde thoracic duct catheterization was attempted via the left venous angle. Successful patients underwent direct thoracic ductography. After the position of the rupture was shown, the thoracic duct was embolized with microcoils and glue.
ResultsThe inguinal lymphography of 16 patients was successful, and the end of thoracic ducts was identified. Retrograde thoracic duct catheterizations were successful in 10 patients, 6 cases showed contrast agent overflow in thoracic ductography, and the thoracic ducts were embolized using microcoils combined with glue. Chylothorax was improved in 16 patients, and 6 cases were completely cured. All patients had no serious complications.
ConclusionIt is an effective and feasible method to treat chylothorax by retrograde thoracic ductography and embolization approach via left venous angle.
