Factors that may contribute to the determination of inoperability may include:\n\n * Anatomical considerations\n\n * No outflow targets\n * No appropriate conduit (i.e. vein for bypass)\n * Long segment occlusions or calcified lesions that predict poor outcome with endovascular approaches.\n * High risk medical conditions\n\n * Unstable cardiac disease.\n * Renal insufficiency\n * History of prior failed revascularization attempts\n * The patient's unsuitability must be confirmed by 2 qualified physicians.\n\n * The attending vascular surgeon will provide the primary assessment.\n * The confirmatory opinion must come from a fully licensed physician. (not a resident)\n * If anatomical considerations are invoked, the second physician may be a vascular surgeon, interventional radiologist, cardiologist, or vascular medicine specialist.\n * If medical co-morbidity is deemed the high risk aspect, then the confirmatory opinion may be obtained from an internist, family physician, cardiologist, vascular medicine, nephrologists, or vascular surgeon.\n* Age \\>18 years and ability to understand the planned treatment\n* Subject has read and signed the IRB approved Informed Consent form\n* Patients for whom the following medication(s) is prescribed must have a one month stable baseline of appropriate/maximally tolerated therapy prior to enrollment: Plavix/asprin therapy, anticoagulation therapy, cholesterol lowering agent, and or blood pressure medication\n* Hematocrit ≥ 28.0%, White Blood Cell count ≤ 14,000, Platelet count ≥ 50,000, Creatinine ≤ 2.0 mg / dL, INR ≤ 1.6 unless on Coumadin, or PTT \\<1.5 x control (to avoid bleeding complications) Patients on Coumadin will be corrected prior to the procedure and must have an INR\\<1.6 at the time of randomization/surgery.\n\nExclusion Criteria:\n\n* Life expectancy \\<6 months due to concomitant illnesses\n* History of bone marrow diseases (especially NHL, MDS) that prohibit transplantation\n* Terminal renal failure with existing dependence on dialysis\n* Known active malignancy or results outside of normal limits from the following tests: PAP, Chest X-ray, PSA, Mammogram, Hemoccult unless follow-up studies reveal patient to be cancer free..\n* Poorly controlled diabetes mellitus (HgbA1C\\>10%)\n* Medical risk that precludes anesthesia (conscious sedation), or ASA Class 5\n* Life-threatening complications of the ischemia necessitating immediate amputation\n* Uncorrected iliac artery occlusion on index side\n* No Doppler signal in the foot (ABI =0)\n* Extensive necrosis of the index limb or other conditions that make amputation inevitable (Rutherford Category 6)\n* Active clinical infection being treated by antibiotics within one week of enrollment\n* Treatment with immunosuppressant drugs (including Prednisone \\> 5 mg per day).\n* Female who is pregnant or nursing, or of child bearing potential and is not using a reliable birth control method.\n* Underwent a major open cardiovascular surgical procedure (carotid endarterectomy, arterial aneurysm or bypass surgery, or coronary artery bypass surgery) or a myocardial infarction within the 3 months prior to randomization\n* Cerebrovascular accident within 6 months prior to randomization."}, 'identificationModule': {'nctId': 'NCT00498069', 'briefTitle': 'Study of Autologous Bone Marrow Concentrate for the Treatment of Critical Limb Ischemia (CLI)', 'organization':
