Choosing the Vascular Access Site Determine type of procedure/sheath size needed Coronary Renal, ilio-femoral Infra-inguinal Support devices; percutaneous AV Consider access sites-any limitations/obstructions Femoral Brachial Radial Co-morbid illnesses/diseases CKD; PVD Bleeding risk
Vascular Access Overview Femoral Brachial Radial (6-9 mm) (4-7 mm) (3-5 mm) Ease of access ++++ ++ + Learning curve short some yes Flexibility in sheath size ++++ ++ + Anticoagulation (cath) no yes yes Complication rates +++ ++ +
Femoral Artery Access Optimal access- Above bifurcation Below inferior epigastric artery Courtesy Dr Z Turi
Femoral Artery Access Landmarks/strategies for achieving access Inguinal crease Bony landmarks Floroscopy over femoral head Doppler guided Ultrasound guided
Femoral Artery Access Can you pick out the skin crease?? Courtesy Dr Z Turi
Femoral Artery Access Double fluoroscopy technique: Identify skin entry site over femoral head with hemostats Re-assess needle entry site just before entering artery Best chance to hit target zone

Femoral Artery Access Sticking until you hit the artery is not a sound or safe strategy! Good access will allow good closure Fellows in July The patient is NOT a pin cushion!! Courtesy Drs Z Turi, And J Hermiller
Femoral Artery Access Front wall stick desirable-micropuncture desirable Pulsatile flow before advancing wire Wire exits needle without resistance-don t push Gain familiarity with exchange catheters Gain familiarity with hydrophilic wires Don t be afraid to ask for help
Femoral Access Site Closure Manual Compression The gold standard; but competency often taken for granted A patient s perspective An attending s perspective
Femoral Artery Closure Manual Compression Works Best when CFA Accessed Courtesy Dr Z Turi
Limitations of Manual Compression Delayed ambulation Patient dissatisfaction/discomfort Time and personnel intensive Vascular complications in anticoagulated pts after successful hemostasis still occur
Vascular Closure Devices VCDs clinically introduced 1994-Vasoseal, and Perclose; Angioseal introduced in 1996 Addressed need for more aggressive anticoagulation and larger bore sheaths for 1st gen stents and atherectomy Early devices failed 10-20% of time Device modifications (x 8) have stream lined and simplified use, and substantially reduced failures
Anatomic Requirements per IFU Closure Devices Common femoral artery (CFA) access location Minimal lumen diameter CFA 4-6 mm (device specific) Absence of severe ASCVD Absence of severe calcification Need femoral angiogram before deployment! 2011 Buyers Guide Endovascular Today

Angio-Seal Evolution Anchor Set Ease of use made it market leader Gear Mechanism Designed with precision engineering to rotate as the device is pulled back by the user. Accurately manages the compressive sealing force. Standardized Deployment Rack Precisely engineered for forward movement while user pulls back on the device. This forward movement guides the compaction tube forward. Automated Collagen Compaction Automated Compaction Rack Engaged Consistent compaction force
Optimize Use of VCDs Take the time to learn how to use closure devices Commit to a device and gain expertise with it Follow the guidelines for use and perform femoral angios prior to all deployments Monitor your outcomes VCDs may fail; become occlusive; or infected Be vigilant and recognize these potential complications
Anatomic Challenges in Using Low or bifurcation stick High stick VCDs Significant ASCVD of CFA Significant calcification of CFA Prior VCD use Severe angulation of sheath entry
Factors that Influence Outcome of VCD Use Patient characteristics Anticoagulation and anti-platelet therapy Procedure type Access site anatomy Device features and performance Operator and institutional experience
Evaluation of Outcomes with Vascular Closure Devices Not one large randomized clinical trial of closure device vs manual compression!! No compelling evidence that 1st generation VCDs lower rates of vascular complications No convincing evidence that one VCD is better than another; although data support notion that Vasoseal was harmful (compared to manual)
Evaluation of Outcomes with 1 st gen Vascular Closure Devices Meta-analyses of outcomes with VCDs (mainly 1 st gen devices) Manual compression may be safer Koreny et al JAMA 2004;4291:350 Manual compression may be safer Nikolsky et al JACC 2004;44:1200
Vascular Closure Devices There is a substantial learning curve with VCDs! Greater experience, multiple modifications of VCDs benefitting efficacy and safety! Balzer et al CCI 2001; 53:174-181

Why Do (femoral) Vascular Complications Persist? Anatomic Stick location; femoral vs radial; vessel size; PVD Procedural Poor puncture technique ; PCI; multiple procedures; anticoagulation; GPI Closure Patient Clinical Manual compression vs VCD use Very thin or obese; gender; renal disease Emergency procedure; shock; AMI
VCD Specific Complications Device failure in anti-coagulated patient to Unable remove device from artery/groin Embolization of device into artery Foreign body reaction to device Infection Nerve entrapment
