NCT ID: NCT06365528 Recruiting - Clinical trials for Deep Vein Thrombosis

Tunneled Peripherally Inserted Central Catheter (PICC) in Adult Patients and Associated Outcomes

Start date: May 6, 2024
Phase: N/A
Study type: Interventional

The aim of this multicenter randomized clinical trial is to compare the tunneling technique of PICC insertion with the non-tunneled insertion technique in the incidence of the combined or isolated outcome of catheter-related bloodstream primary infection, thrombosis, obstruction, and accidental dislodgement in the adult population within a period of up to 30 days.

NCT ID: NCT05780619 Recruiting - Stenosis Clinical Trials

Diagnostic Performance of the Resistance Index (RI) for the Assessment of Cerebral Vasoreactivity in Transcranial Doppler

REVACEIR
Start date: June 9, 2023
Phase:
Study type: Observational

Routine revascularization of asymptomatic carotid stenosis is questionable as optimal medical therapy has significantly reduced the risk of stroke. Therefore, it is crucial to identify high-risk patients who may still benefit from carotid revascularization. In 2017, the ESC guidelines clarified the criteria associated with a high risk of stroke despite optimal treatment to consider a revascularization procedure, including altered cerebral vasoreactivity. However, cerebral vasoreactivity using transcranial Doppler ultrasound is reserved for qualified centers. It requires a technical platform and trained personnel, is time-consuming and generally not readily available. A simpler test is therefore necessary. The goal is to quickly and easily detect patients with normal vasoreactivity who do not benefit from the cerebral vasoreactivity test (reference standard) and to reserve the time-consuming cerebral vasoreactivity test for patients likely to have altered vasoreactivity. The hypothesis of the study is that on a routine measure in transcranial echo-Doppler, the resistance index (RI), can predict the response to the cerebral vasoreactivity test. With this new test, it will be possible to select patients who do not benefit from pharmacological cerebral vasoreactivity testing ("true negatives"). Thus, the time-consuming cerebral vasoreactivity test will be reserved only for patients with a possibility of impaired vasoreactivity.

NCT ID: NCT05512455 Recruiting - Occlusion Clinical Trials

Accuracy of Various Virtual Articulator Mounting Procedures: An in Vivo Study

Start date: April 1, 2022
Phase:
Study type: Observational

the aim of this study was to evaluate the accuracy of the various virtual articulator mounting procedures.

NCT ID: NCT05507164 Recruiting - Occlusion Clinical Trials

Characterization of the Temporo-masseteric Nerve Block (TMNB) in Healthy Subjects

Start date: October 10, 2022
Phase: Phase 2
Study type: Interventional

The proposed pilot study is aimed at preliminary characterization of the TMNB injection in 20 healthy volunteers. Assessment of bite-force distribution and surface electromyographic activity of the temporalis and the masseter muscles, at rest and clench, before and after unilateral TMNB injection, will be the primary outcome measures. Post-injection assessments will be performed at 30 minutes, 2 hours, and 2 weeks after the injection. Participants will be surveyed regarding their experience receiving the TMNB injection (secondary outcomes).

NCT ID: NCT03149913 Recruiting - Stenosis Clinical Trials

Local Paclitaxel or Balloon Angioplasty Below the Knee

SAMBA
Start date: December 15, 2016
Phase: N/A
Study type: Interventional

Patients with claudication or critical limb ischemia will be treated either with uncoated balloons or paclitaxel coated balloons in order to enhance the vessel patency in stenosed or occluded below the knee arteries
