ANCHOR - Aneurysm Treatment using the HeliFX Aortic Securement System Global Registry

Aims: Endografts are often employed in the treatment of Abdominal Aortic Aneurysms.  The Aptus HeliFX Aortic Securement System allows the surgeon to use EndoAnchors, similar to small screws, to secure the endograft to the wall of the aorta, providing additional fixation and sealing of the endograft in place.  The system can be used in either:          

  • patients who already have an endograft (previously placed) that the surgeon thinks will benefit from additional securing or,
  • patients who are undergoing placement of an initial endoqraft repair, particularly those whose anatomy may make securing the graft without the use of EndoAnchors difficult (the surgeon believes the endograft may be at risk of not “fixing” to the wall of the aorta, or not sealing well).

This Global Registry will allow for the collection of clinical data on patients who have had the EndoAnchors placed in their endograft and to expand the knowledge of how well the system is working over a broad spectrum of geographies and a variety of practicing clinicians.
Diagnosis: Abdominal aortic aneurysm (AA); Endoleak

Accuracy of Direct Oral Anticoagulants (DOAC) Dispstick (DOASENSE) in patients treated peri-opratively with DOACs- Pilot Study

Aims:The objective of the study is to quantify the composite outcome of thromboembolic events and major bleeding among patients who need a DOAC interruption and follow our institutional protocol. And to define the safety of our perioperative DOAC interruption strategy
Diagnosis: Venous thromboembolism or Atrial Fibrillation and scheduled for a procedure that requires interruption of DOAC medication.
Principal Investigator: Alfonso Tafur, MD
IRB Approval Number: EH19-243
Sponsor: NorthShore
Contact: Interested patients may contact Anat Sharonat at 847.570.3861 or email: asharon@northshore.org
Open to Enrollment: Yes


C-TRACT: Chronic Venous Thrombosis: Relief With Adjunctive Catheter-Directed Therapy

Aims: The purpose of this study is to determine if the use of image-guided, endovascular therapy (EVT) is an effective strategy with which to reduce Post Thrombotic Syndrome (PTS) disease severity and improve quality of life in patients with established disabling iliac-obstructive post thrombotic syndrome (DIO-PTS).
Diagnosis: Illiac Obstructive Post Thrombotic Syndrome
Principal Investigator: Alfonso Tafur, MD
IRB Approval Number: EH19-245
Sponsor: Washington Univerity School of Medicine
Contact: Interested patients may contact Anat Sharon at 847.570.3861 or email: asharon@northshore.org
Open to Enrollment: Yes


RIETE: Computerized Registry of Patients with Venous Thromboembolism

Aims: The RIETE Registry is a multidisciplinary project aimed at providing information on the Internet that helps physicians  improve their knowledge on the natural history of thromboembolic disease, particularly in those subgroups of patients who are usually not recruited in randomized clinical trials (pregnant women, elderly patients, disseminated cancer, severe renal insufficiency, patients with contraindications to anticoagulation therapy pr extreme body weight), with the purpose of decreasing mortality, frequency of thromboembolic recurrences, as well as bleeding complications and arterial events. RIETE also aims to create predictive scores that help physicians to better identify patients with high risk of developing some of these complications.
Diagnosis: Acute deep vein thrombosis (DVT), pulmonary embolism (PE) and/or superficial venous thrombosis (SVT)
Principal Investigator: Alfonso Tafur, MD and Lauren Cote, RN
IRB Approval Number: 
EH11-337
Sponsor: Manuel Monreal, Foundation for the study of VTE diseases
Contact: Interested patients may contact Lauren Cote, RN at 847.570.2428 or lcote@northshore.org
Open to Enrollment: Yes 


Direct Oral Anticoagulants (DOACs) Versus LMWH +/- Warfarin for VTE in Cancer: A Randomized Effectiveness Trial (CANVAS)

Aims: The purpose of this study is to compare the benefits, harms, and burdens of two different approaches to anticoagulation therapy in patients with cancer. Although DOACs are FDA-approved, they have not been extensively studied in patients with cancer.
Diagnosis: Cancer with a blood clot
Principal Investigator: Alfonso Tafur, MD
IRB Approval Number: EH17-042
Sponsor: Alliance Foundation Trial
Contact: Interested patients may contact Elita Fine at 847.570-2698
Open to Enrollment: Yes
