Abstrakt: Objectives: To analyze and describe the association between the development of venous aneurysms of the mayor vessels in patients with lymphatic malformations.
Material and Methods: Retrospective review of patients diagnosed with both VA and LM from 1993 to 2014 and a descriptive analysis of clinical course was performed.
Results: We found 6 patients, 50% females, who had LM and VA confirmed with imaging techniques. All were diagnosed between 20 weeks- 12 years of age. LM were found within the thoracic cavity (n= 4), intrathoracical-cervical area (n= 1) and lower extremities (n= 1). In most cases the dilated veins were near the LM and thus, the mediastinal vessels were most commonly affected (superior vena cava-innominated (n= 1), venous jugulosubclavian confluence (n= 2), superior vena cava (n= 2) and popliteal vein (n= 1)). A total of 4 patients required surgical treatment of the LM with complete excision in 2 of the cases. Patients with a prenatal diagnosis of lymphatic malformation were most likely to present venous aneurysms at birth (n= 2), however the remaining patients (without prenatal diagnosis) developed them later on (average 6 years). Unlike lower extremity aneurysms, none of these aneurysms grew or required antiplatelet therapy; local thrombosis developed in one which resulted in pulmonary thromboembolism and one developed mitral valve insufficiency (regurgitation?) which required valve replacement.
Conclusion: VA is extremely rare, and there is not therapeutic algorithm, therefore treatment should be individualized.
