Sheath Size Up and Down With Single Proglide - A Technique for Achieving Hemostasis With Use of Large Size Delivery System During Endovascular Graft Placement.

Background: A total percutaneous approach for management of aortic pathologies with endovascular grafts requires the use of large size delivery-systems. The diameter of these delivery systems usually exceeds the recommended sizes for most of the currently available percutaneous closure devices. A safe, effective and simple vascular access site closure device is desirable for success for percutaneous procedures for aortic pathologies. Hence, we aim to study safety and effectiveness of the use of a single suture based vascular access closure device (ProGlide) using a technique involving serial up and downsizing of the sheath size to achieve access site hemostasis in patients undergoing endovascular graft placement using femoral artery approach.

Materials And Methods: We studied all consecutive patients who underwent endovascular grafting from January 2018 to December 2019. It is a retrospective observational study comparing procedural and short-term outcomes between single ProGlide use and surgical cut-down for femoral access site closure. We excluded patients with femoral artery minimal luminal diameter less than 5 mm, the presence of an aneurysm of the femoral artery, ≥180 degrees of calcium present at femoral/ external iliac artery and history of any vascular closure device use in the last six months.

Results: We included 30 patients in single ProGlide group and 30 patients in the surgical cut-down group. One-third of the procedures were urgent procedures in the single Proglide group. Single ProGlide was successful in 93.34% patients and failure (6.66%) was seen due to hematoma and pseudoaneurysm in one patient each detected before discharge. The primary end-point defined by the success of procedure did not differ between the two groups. There were higher complications in the surgical group till 30 days as evidenced by infection, hematoma and neuronal injury. The secondary end-point, defined by the composite of complication events after discharge till 30 days was significantly higher in the surgical group (P-0.005) CONCLUSION: In patients with suitable femoral artery anatomy who undergo endovascular graft placement, effective hemostasis can be achieved safely using up and downsizing of the sheath with a single suture-based technique (Proglide). The results of the study could be considered hypothesis generating and needs to be confirmed in a randomized controlled trial before being adopted in clinical practice.
