title: [Endovascular microembolization of the posterior auricular artery in comprehensive surgical management of capillary angioma of the floor of the auricle].
abstract: The article deals with the description of a rare clinical case wherein a 44-year-old female patient presenting with bleeding capillary angioma of the left auricle obstructing the auditory passage was fist subjected to endovascular microembolization of the posterior auricular artery by means of polyvinyl alcohol (PVA-500), followed by a second stage of virtually bloodlessly surgical removal of the tumour carried out five days thereafter. This case report once again points to feasibility of combined, i. e. endovascular and conventional surgical management of capillary angiomas. Preoperative microembolization of a bleeding haemangioma arrests haemorrhage from the tumour, resulting in the decreased size thereof, as well as leading to circumscribing the tumour from healthy tissue. Attention is paid to the fact that embolization of the auricular artery should be performed only after a thorough angiographic evaluation of the pattern of the blood flow in the tumour and adjacent vessels by means of the technique of selective catheterization and using only the officinal emboli.
