Brief Summary
The purpose of this study is to evaluate the safety of increasing doses of intra-thrombus Plasmin (Human) in acute peripheral arterial occlusion (aPAO). The ability of these Plasmin doses to dissolve the clots will be estimated by arteriography.

Eligibility Criteria
You may qualify if:
- Age ≥ 18 years.
- Women of childbearing potential must use adequate contraception for the duration of the study and must have a negative pregnancy test prior to study entry.
- Unilateral limb ischemia: SVS acute ischemia Category I or IIa.
- Onset of symptoms \</= 14 days.
- Thrombosed (non-embolic) infrainguinal graft (synthetic, autologous, or single outflow composite) or infrainguinal native artery. For native arteries, only occlusions of ≥ 10 cm in length are eligible.
- Diagnosis of occlusive thrombus in the graft or artery by arteriography after Informed Consent is obtained.
- Ability to traverse the thrombus with a guidewire.
- Signed informed consent prior to study entry.
You may not qualify if:
- Clinical evidence of significant disease that may interfere with the patient successfully completing the trial.
- Women who are pregnant or lactating, or first 10 days post-partum.
- Previous hemorrhagic stroke at any time. Thrombotic or embolic stroke or cerebrovascular events (including transient ischemic attack (TIA)) within one year.
- Intracranial or spinal neuro-surgery, or severe intracranial trauma in the last 3 months. Major surgery, organ biopsy, or major trauma within the last 10 days. Lumbar puncture or non-compressible arterial puncture in the last 10 days. Intra-ocular surgery within the last 10 days.
- Uncontrolled arterial hypertension, defined as a systolic blood pressure \> 180 mmHg or diastolic blood pressure \> 110 mmHg.
- Known intracranial neoplasm, aneurysm, or arterio-venous malformation.
- Platelet count \< 75 x 10e9/L.
- Occlusion of a graft within 6 months of placement.
- Medically unable to tolerate an open vascular procedure.
- Known prothrombotic condition.
- Hemoglobin \<10.0 g/dL
- Impaired renal function or renal disease that constitutes a contraindication to contrast angiography, including creatinine \> 2.0 mg/dL or subjects on renal dialysis.
- Treatment with a glycoprotein IIb/IIIa class of platelet inhibitor within the past 5 days, for example, abciximab (ReoPro®), eptifibatide (Integrilin®) or tirofiban (Aggrastat®).
- Treatment with warfarin (Coumadin®) and with an INR of \>1.7 (elevated INR at screening may be corrected prior to study enrollment.)
