Official title: Prospective Study on the Role of Intravenous Unfractionated Heparin Following Digital Replantation and Revascularization

Run by Centre hospitalier de l'Université de Montréal (CHUM) · NCT04725201 · Data updated 2026-11-12

This study is testing if giving heparin through an IV can help improve the chances of success for people who have had their fingers amputated and are getting them reattached.

Is this trial a fit for you?

Likely a good fit

Ideal candidates are individuals who have undergone traumatic digital amputation and are accepted into the replantation program at the Centre hospitalier de l'Université de Montréal.

Probably not a fit

Patients on anticoagulants or with contraindications for heparin, as well as those with more severe injuries, will not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This study investigates the effectiveness of intravenous unfractionated heparin in enhancing the success rates of digital replantation and revascularization in patients who have experienced traumatic finger amputations. Participants will receive a continuous intravenous drip of heparin to assess its impact on the viability of the replanted digit compared to those who do not receive the treatment. The study will also evaluate potential postoperative complications associated with heparin use, such as bleeding and thrombocytopenia, while considering various patient factors like smoking status and comorbidities.

Why it matters

Potential benefit: If successful, this approach could significantly improve the outcomes of finger replantation surgeries, leading to better recovery and functionality for patients.

How similar studies have gone: While the use of heparin in this specific context is novel, similar studies in other surgical fields have shown promising results with anticoagulant therapies.
