Abstract
BACKGROUND: Proper management of patients with thromboangiitis obliterans (TAO) or cannabis-associated arteritis (CAA), presenting with critical lower limb ischaemia (CLI) remains controversial, and data are limited.
PATIENTS AND METHODS: Patients with TAO or CAA presenting with CLI between 2011 and 2016 were retrospectively evaluated. Patients requiring primary intervention were excluded. Conservative treatment included: (a) weight-adjusted bemiparin plus six hours/day intravenous iloprost for 28 days, (b) aspirin (100 mg/day) plus cilostazol (100 mg twice/day) after discharge, and (c) strict recommendations/monitoring for smoking cessation. Main outcomes included symptom recession, ankle-brachial index (ABI) improvement, and healing of lesions at the time of discharge as well as amputation, revascularization, and abstinence rate during follow-up.
RESULTS: Overall, 23 patients (TAO: 15; CAA: 8) were included within six years, none of the patients reported any other factor than smoking. All patients presented with rest pain and 12 patients with ulcer or necrotic lesions. Mean ABI measurement at presentation was 0.46 ± 0.2, after 28 days of treatment, all patients showed improvement regarding clinical picture and ABI measurement (0.54 ± 0.1; p < 0.05). During follow-up, only three patients underwent bypass surgery and two patients underwent major amputation, although the smoking abstinence rate was very low (13 %).
CONCLUSIONS: Intravenous iloprost plus bemiparin for 28 days together with per os aspirin plus cilostazol seem to produce promising results in patients with TAO/CAA, treated for CLI, even with a low smoking abstinence rate. However, larger series are needed to further evaluate inter-group differences and potential prognostic factors.
