Morphological characteristics of venous angiodysplasia of the face and scalp

Objective.Studying of morphological characteristics of venous angiodysplasia of the face and scalp. Materials and methods. The operation material (soft tissues of the face and scalp) was investigated in 20 patients for studying of morphological characteristics of venous dysplasia. In the histological investigation frame the material was fixed and processed in accordance to conventional method, the tissue slices were colored with hematoxilin and eosin. In 7 observations immuno–histochemical investigation with CD34 antibodies (clone QBEND10) and S100 (polyclonal) was applied. Results. Basing on patho–histological investigations of the operation material in 8 patients, morphological features, characteristic for arterio–venous angiodysplasia, were revealed, what may constitute the recurrence cause in postoperative period. Conclusion.The recurrence prognosis and further surveillance of patients with venous angiodysplasia demands decision of the question concerning the presence of arterio–venous component in clinically and instrumentally confirmed simple venous angiodysplasia, concerning every patient.
