Study summary

Treatment of patients with end-stage renal disease and critical limb ischemia still poses challenges to vascular medicine due to limited survival, comorbidities and infrapopliteal involvement of arteriosclerosis in these patients.

Most optimal vascular therapy mode has not been finally decided in these patients.

Therefore retrospective analysis of patients receiving open surgical and endovascular revascularisation was performed.

Read the detailed description

Query of internal clinical database for identification of patients (2009-2017)with end-stage renal disease and critical limb ischemia, receiving either open surgical (Group I "OR") or endovascular revascularisation (Group II "EVT").

Furthermore, retrospective comparison as to morphological criteria (lesion length, peripheral run-off, plantar arch) and comorbidities.

Prospective follow-up of identified patients by means of telephone contacts and/or clinical examination of evaluation of Long-term outcome measures (Overall survival, Amputation-free survival, wound healing)

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Mar 26, 2020, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
