|Lower Limb Ischemia||Device: 'Indigo' Mechanical thrombectomy system||Not Applicable|
A detailed registry has been designed and approved to be used world wide in vascular and trauma centres, already providing endovascular service for the management of critical limb ischaemia (CLI).
Recent campaigns have shown little is done to improve flow to the lower limbs (legs) of patients to avoid amputation rates. During this time many devises have been used and available on the market. The 'Indigo' system by Penumbra was originally designed from the acute stroke system "ACE". Similar principles were applied in designing the 'Indigo' system. This is currently being used in many centres to manage acute clot causing lower limb ischaemia, however no official registry or international clinical trial has been done to show its significance in managing this disease.
The investigator groups, have created this to come up with enough data to evaluate the Indigo system in the management of (ALI) and offer tips and tricks to other clinicians. The aim is for a single arm, multicenter, retrospective analysis of patients in whom (ALI) was performed with the Penumbra/Indigo System (study device), and gather greater data and information than the PRISM trial in 2013-2014 which obtained only 79 patients.

Acute or Chronic clot
If chronic clot, no intervention given via Indigo
Device: 'Indigo' Mechanical thrombectomy system
Removal of acute clot from the artery causing ischaemia, using the mechanical aspiration system by Penumbra Inc called "INDIGO"
- Technical success using the Indigo system. [ Time Frame: Time to event anaylsis. Primary patency results are immediate after the case on the final angiogram images. ]
Intraoperative technical success defined as the restoration of antegrade blood flow with complete or near complete (95% by volume) removal of the thrombus or embolus (70% threshold). This is assessed using imaging modalities (USS/Doppler/Fluroscopy) and clinical assessment of the affected limb.
See for this definition the enclosed citation. In conclusion, the primary outcome measure will be improvement in blood flow across a lesion assessed by the improvement in Thrombolysis in Myocardial Infarction (TIMI) score that was adapted to peripheral arteries. Concomitant balloon angioplasty or stent placement in addition to VAT was considered a complementary treatment. Additional thrombectomy treatments, such as thrombolysis and mechanical thrombectomy, were considered technical failures.Target lesions were grouped anatomically into above-the-knee(ATK) or below-the-knee(BTK) lesions.
