Unrecognized ConditionNCT03477071
A 15-year Single Center Experience of Endovascular Treatment of Transplant Renal Artery Stenosis
An observational study of Unrecognized Condition, run by Centre Hospitalier Universitaire de Nice.
Trial summary
Stenosis of the renal graft arteries occurs in 1 to 26% of cases and can damage the graft. Endovascular treatment is first-line treatment. The main objective of this study is to identify the predictive factors of failure of peri-anastomotic. Read more about this study

About this study
Official title: A 15-year Single Center Experience of Endovascular Treatment of Transplant Renal Artery Stenosis: Evaluation of Post-operative Outcomes
Stenosis of the renal graft arteries occurs in 1 to 26% of cases and can damage the graft. Endovascular treatment is first-line treatment. The main objective of this study is to identify the predictive factors of failure of peri-anastomotic.
Read the detailed description
The aim of this study was to evaluate the post-operative outcomes following endovascular treatment of TRAS (Transplant Renal Artery Stenosis).
This retrospective, monocentric study included patients with peri-anastomotic stenosis of the renal graft from 2000 to 2017. The stenosis is defined by a reduction of at least 50% of the arterial diameter during arteriography. Technical success was defined as residual stenosis less than 30% of the arterial diameter after the procedure.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Angioplasty for Transplant Renal Artery Stenosis (TRAS)Procedure or surgery
Also called Endovascular treatment
The angioplasty is an endovascular treatment for artery stenosis, which could be associated with stenting or not.
What is being measured
The primary outcome is the main question the study is designed to answer.
The technical success rate of endovascular treatment
The stenosis is defined by a reduction of at least 50% of the arterial diameter during arteriography. Technical success was defined as residual stenosis less than 30% of the arterial diameter after the procedure
Measured: 30 days
Secondary outcomes (2)
Morbidity rate
Morbidity rate is defined as the development of post-operative complications. Minor and major complications are recorded, corresponding to Clavien Dindo classification
Measured: 30 days
Mortality rate
All death are recorded to identify the mortality rate
Measured: 30 days

Questions about this trial
What is this clinical trial studying?
An observational study of Unrecognized Condition, run by Centre Hospitalier Universitaire de Nice.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 2 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 26 Mar 2018. Status can change between updates, so confirm with the study contact before making plans.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
The technical success rate of endovascular treatment (time frame: 30 days). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 26 Mar 2018.
