Trial summary

Background: PICC-related thrombosis have shown a slightly different pattern of frequency and risk factors, compared with traditional CVC; because of the increasing diffusion of PICCs, they are becoming a somehow independent pathology, still under investigation; no pharmacological prevention has proved to be effective.

About this study

Official title: Observational Study With Ultrasonographic Screening for Early Detection of PICC-related DVT, Results of Early Beginning of Anticoagulant Treatment

Background: PICC-related thrombosis have shown a slightly different pattern of frequency and risk factors, compared with traditional CVC; because of the increasing diffusion of PICCs, they are becoming a somehow independent pathology, still under investigation; no pharmacological prevention has proved to be effective. Aim of this study is to estimate the cumulative incidence of thrombosis in a cohort of patients carrying a PICC-line CVC, monitored to allow an early detection and prevention of complications related to the presence of asymptomatic deep venous thrombosis, and to explore the role of several potential risk factors.

Methods: in a prospective observational cohort we will enroll 150 consecutive patients having a PICC inserted by our team; clinical characteristics, comorbidities and main features of catheter positioning procedure will be registered; patients will be followed with clinical and echographic scheduled controls, weekly for the first month, then monthly; patients with PRDVT will be treated with LMWH and recontrolled weekly until removal of catheter

Read the detailed description

All PICCs are positioned by trained physicians and nurses, after ultrasonographic screening of the whole upper limbs venous district, axillary, subclavian and jugular veins for detecting possible pre-existing thrombosis; positioning is performed with real-time ultrasonography guide with a portable device. Patients are recontrolled one week after positioning; patients who report pain, swelling, fever, skin colour changes, exit site tenderness, or any symptom suspected for thrombosis or infection, are immediately seen. A duplex ultrasound complete examination of the upper limb and neck vessels is performed, and at the same time the whole arm and the exit site is inspected to exclude infections; diagnostic criteria for DVT include incompressibility of the vein and direct visualisation of PICC-surrounding thrombus; in uncertain cases, a doppler examination is performed.If the examination is negative for thrombosis, further controls are performed at 2,3,4 weeks after positioning, then once a month.If a DVT is detected, we register the position and extension of the thrombus, and its main characteristics (clot, mural or occlusive thrombosis); the catheter is left in place and a therapy is prescribed with LMWH at full doses, according with ACCP guidelines 2008 (confirmed in 2012 edition). Then, the patient is recontrolled weekly until removal of the catheter.

Questions about this trial

What is this clinical trial studying?

An observational study of Central Venous Catheter Thrombosis, run by University of Turin, Italy.

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 1 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 11 Feb 2013. 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?

early detection of PRDVT (time frame: 1 yr). 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 11 Feb 2013.
