The abnormal systemic artery to the left lower lobe (ASALLL): a report of two cases

In this study, we report 2 cases of abnormal systemic artery to left lower lobe (ASALLL) with hemoptysis. In case 1, a 15-year-old boy experienced intermittent hemoptysis for over a year. After diagnosis of ASALLL by chest-enhanced computerized tomography (CT), interventional embolization was performed to treat the abnormal arteries, and the patient was cured and discharged. Case 2 is a 36-year-old man with chest pain and hemoptysis recurring for many years and aggravating for 5 days. ASALLL was diagnosed by chest-enhancement CT examination. After thoracoscopic resection of the left lower lobe, the patient was discharged. These cases show that the clinical manifestations of ASALLL are mainly recurrent hemoptysis symptoms. For patients with hemoptysis, the disease should be found and not limited to symptomatic treatment. Chest-enhanced CT scanning can diagnose ASALLL, and interventional embolization or surgical treatment can be selected for treatment.
