[Current trends in diagnosis and treatment of arteriovenous angiodysplasia]
Abstract:
A total of 240 patients with arteriovenous angiodysplasia (AVD) were examined and treated in A.V. Vishnevsky Institute of Surgery during 1997-2009. Embolization was performed in 196 (81.7%) patients. Staged embolization was the principal treatment modality in 84 (35%) patients presenting with inoperable lesions. The mean number of sessions was 3.6. Intraoperative embolization using hydrogel embols, Gianturco coils, and 96% alcohol was done in 17 (7.1%) patients. Radical surgery with the removal of angiomatous tissues was given to 33 (13.8%) patients. Palliative resections were made in patients with extensive lesions and impossibility of total removal of angiomatous tissues. Minor and major amputations were needed in 15 patients. It is concluded that intervention for microfistulous and confined macrofistulous lesions should be performed only in case of absolute indications for surgery. That in asymptomatic or subclinical cases is justified only for minor surface lesions fit for radical resection. Minor amputation is indicated in certain patients with arteriovenous fistulas on distal limb segments. Extensive delayed resections should be planned with the use of plastic surgical techniques (autodermoplasty using free flaps, mobilized flaps, and flaps with microvascular anastomosis).
