Brief Summary
The principal research question is which treatment modality between open surgical,
endovascular and conservative therapy is the most effective in terms of limb salvage,
survival and reinterventions in patients with critical limb ischemia
Detailed Description
The target population consists of patients suffering from critical limb ischemia (CLI)
lasting more than 2 weeks. CLI is defined as rest pain or tissue loss (Fontaine stages III-IV
or Rutherford classes 4 to 6) and/or ankle-brachial index < 0.40. Patient with acute
limb-threatening ischemia, bone fractures in the relevant areas, nonatherosclerotic disease
(e.g. arteriitis) and documented hypercoagulable diseases will be excluded from this study.
There will be no experimental or control groups. The comparison groups will be:
Group 1: Best endovascular treatment (angioplasty +/- stent) Group 2: Best surgical treatment
[bypass (vein or prosthetic)] Group 3: Femoral artery patchplasty +/- profundoplasty (+/-
endovascular treatment) Group 4: Best conservative treatment
The proposed sample size amounts to 1200 patients.
To be assessed for eligibility (n=1200) To be allocated to trial (n=1000) To be analysed
(n=900)
In CRITISCH registry, randomization or blinding is not feasible, because optimized standard
care will be performed as established at each participating centre (best medical treatment).
Data storage, validation, monitoring, update, backup and analysis will be performed centrally
following established procedures. Web-based software will be used to develop a data model
representing the data structure. The data validation will include standard data validation
techniques such as the manual review of selected variables and the routine check of missing
and outlying data points. Regional staff will be instructed and supervised by study nurse,
who will perform the study monitoring. Assessment of relevant prognostic factors during the
statistical analysis will prevent biased results due to the non-randomized design and the
potential structural inequality.

Conditions
Conditions usually refer to a disease, disorder, syndrome, illness, or injury. In ClinicalTrials.gov,
conditions include any health issue worth studying, such as lifespan, quality of life, health risks, etc.
Interventions
Interventions refer to the drug, vaccine, procedure, device, or other potential treatment being studied.
Interventions can also include less intrusive possibilities such as surveys, education, and interviews.
Study Phase
Most clinical trials are designated as phase 1, 2, 3, or 4, based on the type of questions
that study is seeking to answer:
In Phase 1 (Phase I) clinical trials, researchers test a new drug or treatment in a small group of people (20-80) for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
In Phase 2 (Phase II) clinical trials, the study drug or treatment is given to a larger group of people (100-300) to see if it is effective and to further evaluate its safety.
In Phase 3 (Phase III) clinical trials, the study drug or treatment is given to large groups of people (1,000-3,000) to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
In Phase 4 (Phase IV) clinical trials, post marketing studies delineate additional information including the drug's risks, benefits, and optimal use.
These phases are defined by the Food and Drug Administration in the Code of Federal Regulations.
