Bronchial Artery and Non-bronchial Systemic Artery Embolization for the Treatment in Patients with Hemoptysis: Analysis of Efficacy of Gelfoam Single Use

ABSTRACT

PURPOSE: To investigate the efficacy of Gelfoam single use for the management of hemoptysis by analyzing patients with recurrence in embolized artery and other artery, respectively. MATERIALS AND METHODS: Between 1992 and 2000, 131 patients (104 men and 27 women, mean age: 54.4 years) with hemoptysis underwent BAE using gelatin sponge only. After puncturing the femoral artery using the Seldinger method, angiographies of the thoracic aorta, the bronchial arteries, the intercostal arteries, and the systemic collaterals which were suspected of bleeding focus and embolization were performed. Gelfoam was used 1x3 mm and 2x3 mm or 2x5 mm by the diameter of feeding arteries. The cumulative hemoptysis control rate and recurrence rate were analyzed from the previously embolized vessels. RESULTS: Hemoptysis were recurred among 34 of 131 patients. Twenty-two patients had a recurrence from the same vessels and 12 from the different ones. Using the Kaplan-Meier method, the cumulative hemoptysis control rate was obtained in the patients with a recurrence from the same vessels: 88.8% in 1 month, 79.9% in 1 year, and 77.3% in 2 year. The reasons for recurrences of the same lesions are as follows; due to the tortuosity of the vessel (n=3); partial embolization through the common trunk formation between bronchial and anterior spinal artery (n=3); by vessel spasms or autogenous thrombus (n=2); due to the contrast media hypersensitivity (n=1). These 9 patients were not treated successfully. In the remaining 13 cases, hemoptysis were recurred due to recanalization of embolized vessels. Among 161 procedure, complications consisted of fever (n=8), dyspnea (n=8), mild chest discomfort (n=7), lower back pain (n=1), and transient lower leg paralysis (n=1), which were improved within several days. There was no serious complication in this study. CONCLUSION: Bronchial artery embolization using Gelfoam alone maybe effective and safe to control hemoptysis.
