Patients
From December 1985 to May 1997, 56 patients underwent bronchial arteriography for life-threatening hemoptysis in our center. Life-threatening hemoptysis was defined as expectoration of at least 200 mL of blood per hour in a patient with normal or nearly normal lung function, production of at least 50 mL of blood per hour in a patient with a chronic respiratory failure, or more than two episodes of moderate hemoptysis (at least 30 mL) within a 24-h period despite the use of IV vasopressin.

Results
The outcomes of the 56 patients who underwent bronchial arteriography are presented in Figure 2.
Discussion
Life-threatening hemoptysis was defined in our series as expectoration of at least 200 mL of blood per hour in a patient with normal or nearly normal lung function, production of at least 50 mL of blood per hour in a patient with a chronic respiratory failure, or more than two episodes of moderate hemoptysis (at least 30 mL) within a 24-h period despite the use of IV vasopressin. We have not taken into account the amount of blood expectorated during a 24-h period since the decision to perform
