We describe herein a case of surgical treatment of a 32-year-old female patient presenting with multilevel post-thrombotic occlusion of deep veins of the left lower limb. Laboratory study revealed high-risk hereditary thrombophilia (homozygous mutation of PAI-1, MTR, heterozygous mutation of MTHFR, MTRR, ITGA2). The first stage included endovenectomy from the common femoral vein with creation of an arteriovenous fistula between femoral vessels. An attempt of endovascular stenting of iliac veins was initially unsuccessful. After 3 months, the woman was rehospitalized to undergo successful endovascular operation with stenting of the iliac veins and common femoral artery on the background of the functioning arteriovenous fistula. The clinical outcome of the operation was good. Follow-up ultrasonographic examinations (ultrasound duplex scanning) were performed at 3, 6, 10 and 13 months after the second operation. The findings of ultrasound duplex scanning at 13 months showed that the stented segments of deep veins were freely patent, with the arteriovenous fistula functioning well. There were no signs of impairments of central haemodynamics, with significant regression of clinical symptoms. The total score by the Villalta scale as compared with the baseline values decreased from 13 to 5.

Given the pattern of deep vein lesions, complexity of open and endovascular operations, and the presence of thrombophilia, we decided to abstain from disuniting the arteriovenous fistula.

This case report demonstrates possibility, efficacy and safety of long functioning of an artificial arteriovenous fistula in a particular patient cohort.

KEY WORDS: post-thrombotic occlusion of deep veins, endovenectomy, arteriovenous fistula, stenting, duplex scanning.
