Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
FemoStop™ II Gold Compression System is a single use system which includes:
• Integrated manometer allows pressure to be adjusted based on patient status
• The inflatable, transparent dome offers precise pressure for effective haemostasis
• Adjustable belt designed to fit securely so small patient movements may not cause the device to slip
• Transparent dome ensures puncture site visibility
The FemoStop™ Gold Compression System will only be used for compression of the femoral artery after vessel cannulation by or on the order of physicians trained in femoral artery compression procedures.
For successful compression, the system must be correctly positioned throughout the procedure so that pressure is applied to the point intended. A disposable belt will be placed under the patient prior to the procedure and readjusted to precise placement on completion of the procedure. The target inflation pressure should be 10-20mmHg above the systolic pressure, or higher if necessary to control the bleeding. Exceeding pressures of 200mmHg may indicate the need to tighten the belt or reposition the dome. Application of FemoStop™ II Gold Compression System is as follows:
1. Pull the red tab to activate the pump
2. Position belt in line with puncture site(s), equal on both sides.
3. Peel back lid, keeping the dome sterile
4. Centre dome over arterial puncture (superior and medial to skin incision). Keep sheath hubs clear of dome rim.
5. Attach belt to arch and fit snug. Ensure arch is level and square across the groin area. Adjust by pulling on appropriate corner of belt to make arch perpendicular to femoral compression site.
6. Inflate dome to 20-30 mmHg
7. Further inflate to 60-80 mmHg and remove arterial sheath. Then quickly increase pressure in dome to be 10-20mmHg greater than systolic BP or higher as necessary to maintain initial haemostasis.
8. After 3 minutes maximum; lower to a maintenance pressure until limb profusion is restored to baseline and haemostasis is maintained. Check pedal pulse periodically to confirm whether or not flow remains in vessel. After appropriate duration as defined by hospital guidelines; lower by 10-20 mmHg every few minutes until you reach zero. Leave in place at low pressure if appropriate. Remove carefully. Dress wound. Discard device.
9. An additional bed rest for minimum of 3 hours.

Adherence to protocol of FemoStop application will be reported in the nursing notes.
Intervention code [1] 317761 0
Treatment: Devices
Comparator / control treatment
Group A receiving FemoStop™ II Gold Compression System for compression of the femoral artery will be compared to Group B vascular closure device.

Vascular devices (VCDs) are readily used at RPH include FemoSeal, Star Close, Angioseal and Mynx. All of the VCDs are applied by the interventionist according to the company's instructions for use under the guidance of DUS. VCD will be determined by clinician preference

Allocation to FemoStop or VCD will be determined by random allocation by computer generated number groups
Control group
Active

Outcomes
Primary outcome [1] 324034 0
Comparison of major and minor groin complications between two groups (patients receiving the FemoStopTM II Gold compression system versus patients receiving a vascular closure device). Groin complications will be assessed by physical examination at the following time points; immediately after application of a femoral artery closure procedure, prior to discharge from recovery to the ward, and before inpatient hospital stay discharge. The groin puncture site will be examined for - Oozing: presence of any leakage of blood from the puncture site. The blood tainted area is < 3 x 3cm2 on the gauze, but it does not reach the level of bleeding. - Ecchymosis (bruising): presence of any skin discolouration associated with pain and minor swelling. - Bleeding: considered present when there is more than 2g/dl loss from baseline of haemoglobin from puncture site. - Haematoma: swelling mass around the puncture site hard, palpable and tender. (Small haematoma: < 5cm in diameter; Large haematoma: > 5cm in diameter). - Pseudoaneurysm: pulsatile mass; presence of a palpable mass with corresponding movement to systole and diastole diagnosed by DUS detecting flow (if clinically indicated). - Retroperitoneal bleeding: moderate to severe back pain associated with hypotension and tachycardia diagnosed by computed tomography (CT) and DUS, if clinically indicated. - Femoral occlusion (thrombosis): complete occlusion of the femoral vessel as detected by the absence of distal foot pulses, and confirmed by DUS detecting flow, if clinically indicated. - Arteriovenous fistula: abnormal communication between the femoral artery and vein produces palpable thrill and bruit sound confirmed by a stethoscope placed over the puncture site, and by DUS detecting flow, if clinically indicated. Minor groin complications include oozing, ecchymosis and small haematoma (less than 5cm). Major complications include large haematoma (more than 5cm), bleeding, retroperitoneal bleeding and pseudoaneurysm
Timepoint [1] 324034 0

Secondary outcome [1] 383592 0
Comparison of major and minor groin complications between two groups (patients receiving the FemoStopTM II Gold compression system versus patients receiving a vascular closure device). Groin complications will be assessed by physical examination at 30-days post-procedure. The groin puncture site will be examined for - Oozing: presence of any leakage of blood from the puncture site. The blood tainted area is < 3 x 3cm2 on the gauze, but it does not reach the level of bleeding. - Ecchymosis (bruising): presence of any skin discolouration associated with pain and minor swelling. - Bleeding: considered present when there is more than 2g/dl loss from baseline of haemoglobin from puncture site. - Haematoma: swelling mass around the puncture site hard, palpable and tender.

Statistical methods / analysis
An intention to treat analysis will be performed to accommodate for patients that are lost to follow-up, or lack of patient compliance. Statistical analysis will be performed using standard t-test, chi-square analysis, or Fischer exact test. Descriptive statistics will be presented for all primary and secondary endpoints. For quantitative variables, the mean values, standard deviation, maximum and minimum, as well as the 95% confidence interval (CI) for the mean will be calculated where relevant. For qualitative variables, absolute and relative frequencies are determined and the 95% CI for proportions are calculated where relevant. A Kaplan-Meier curve analysis looking at freedom from local groin complication will be conducted.

Anonymised data will be entered into an excel spreadsheet. The statistical package, STATA®, version 16.0 will be used for analysis. A p-value of <0.05 will be used for statistical significance.
