Despite the progress of therapeutics these statistics haven't changed. Critical limb ischemia is a clinical diagnosis but should be supported by objective tests. None of theses tests (toe blood pressure (TBP), transcutaneous oxygen pressure (TcPO2) and skin perfusion pressure (SPP)) have proven to be enough specific or sensitive, more so they are time consuming, can be subject to several artifacts and may be in some cases discordant making diagnosis difficult. Fluorescence angiography has long been used in ophthalmology for the evaluation of the microcirculation of the retina. Infracyanine remains within the intravascular space allowing the visualization of the vasculature to a depth of 10 mm. With the Fluobeam system, images to a maximal width of 20 cm can be obtained therefore allowing the evaluation of the tissue perfusion of the entire foot.\n\nMethod: Fluorescence angiography is performed in the laboratory in the same time as TCPO2, TP and SPP. Infracyanine is injected in an antecubital vein and visualization and signal acquisition carried out using a specific camera device (Fluoptic SAS, France) producing the time course of hemodynamic parameters (slope, amplitude, saturation time).\n\n30patients will be evaluated with correlation between data obtained by fluorescence angiography and too blood pressure"}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'maximumAge': '99 Years', 'minimumAge': '18 Years', 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion Criteria:\n\n* patients with peripheral artery disease and suspicion of critical limb ischemia\n\nExclusion Criteria:\n\n* pregnant women'}, 'identificationModule': {'nctId': 'NCT02820467', 'acronym': 'FLUORESCENCE', 'briefTitle': 'Use of Indocyanine Green Angiography in Critical Limb Ischemia', 'organization': {'class': 'OTHER', 'fullName': 'University Hospital, Grenoble'}, 'officialTitle': 'Study of Parameters of Infracyanine Angiography as Diagnostic Tool of Critical Limb Ischemia', 'orgStudyIdInfo': {'id': '38RC15.212'}}, 'armsInterventionsModule': {'armGroups': [{'type': 'EXPERIMENTAL', 'label': 'patients with suspicion of CLI', 'description': 'patients presenting with peripheral artery disease and suspicion of critical limb ischemia as assessed by TASK II consensus 30 patients will be enrolled and will benefit of measures of TcPO2, too systolic blood pressure and skin perfusion pressure and in the same time angiography with fluorescence (Indocyanine grey 0.05 mg/kg by intravenous injection', 'interventionNames': ['Device: fluorescence angiography']}], 'interventions': [{'name': 'fluorescence angiography', 'type': 'DEVICE', 'description': 'Injection of indocyanine grey in an antecubital vein at the posology of 0.05 mg/kg', 'armGroupLabels': ['patients with suspicion of CLI']}]}, 'contactsLocationsModule': {'locations': [{'city': 'Grenoble', 'status': 'RECRUITING', 'country': 'France', 'contacts': [{'name': 'christophe seinturier', 'role': 'CONTACT', 'email': 'cseinturier@chu-grenoble.fr', 'phone': '0033476765547'}], 'facility': 'CHU grenoble', 'geoPoint': {'lat': 45.17869, 'lon': 5.71479}}], 'centralContacts': [{'name': 'christophe seinturier, MD', 'role': 'CONTACT', 'email': 'cseinturier@chu-grenoble.fr', 'phone': '0033476765547'}], 'overallOfficials': [{'name': 'christophe seinturier, MD', 'role': 'PRINCIPAL_INVESTIGATOR', 'affiliation': 'CHU Grenoble france'}]}, 'ipdSharingStatementModule': {'ipdSharing': 'UNDECIDED'}, 'sponsorCollaboratorsModule': {'leadSponsor': {'name': 'University Hospital, Grenoble', 'class': 'OTHER'}, 'responsibleParty': {'type': 'SPONSOR'}}}}
