How to Improve Safety Take time to do puncture right Use fluoroscopy and/or ultrasound Angiogram every femoral puncture
Local Complications of FA Access: 2-10% Hematoma (1-12%) Pseudoaneurysm (1-6%) AV fistula (<1%) Vessel laceration (<1%) Free bleeding Intimal dissection Ante- or retro-grade Acute vessel closure (<1%) Thrombosis (small artery lumen) Retroperitoneal hemorrhage (0.1-0.9%) Thickening of the perivascular tissues Neural damage Infection Venous thrombosis Pericatheter clot Montreal Heart CCI 3/2001 1.8%/4% (7,953/3,868) Complications persist despite availability of vascular sealing devices.
Why Complications of Manual Closure Persist Puncture technique Sheath management Adjunctive drug therapy Sicker population Age, gender, comorbidity Coexistent vascular disease Inherent limitations of technique

Femoral Head and the CFA Bifurcation 1.5% 4.0% V IV III II 17% 22% 55.5% I Number of patients I: 111 II: 44 III: 34 IV: 8 V: 3 Below inferior border At inferior border Below center of head At center of head Above center of head n=200
Consequences of Low Arterial Puncture Low puncture into the SFA and PF: Pseudoaneurysm 2 inability to compress AV fistula Thrombosis - embolism Occlusion with large sheaths Primarily due to Low stick Inadequate compression time Aggressive anticoagulation
High Puncture High puncture of the femoral artery: Increases risk of retroperitoneal bleeding
The Promise of Vascular closure Devices Patient comfort and convenience Decreased Time to hemostasis Early ambulation Shorter hospital stay Decreased overall procedure-related hospital costs Decreased complication rates

VCDs-The Promise Meta-analysis of 30 randomized trials Efficacy Shorter time to hemostasis- mean difference 17 min Decreased duration of bedrest- mean difference 10.8 hours Decreased hospital length of stay- mean difference 0.6 days Koreny, Riedmuller and Nikfardjam et al., JAMA. 2008;291:350-357
VCDs-The Promise Decreased Vascular Complication rate Pseudo aneurysm Arteriovenous fistula Retroperitoneal hematoma/hemorrhage Femoral artery dissection Bleeding Femoral artery thrombosis

Vascular Closure Devices Active Approximators mechanically secures arteriotomy effects closure through approximation of margins or mechanical fixation using a clip, a suture or a plug Passive Approximators devices which assist or accelerate hemostasis, enhance coagulation, utilizing gels or sealants Novel devices simulate manual compression or create short intramural tracts to achieve hemostasis Topical hemostasis patches which accelerate hemostasis

Moral of the Learning Curve Learn one or two devices and learn them extremely well Consider an additional device for special circumstances Remember that manual compression is always an option

AHA Recommendations 1. Use of VCDs is reasonable after invasive cardiovascular procedures performed via the femoral artery to achieve faster hemostasis, shorter duration of bedrest, and possibly improved patient comfort 2. VCDs should not be used routinely for the specific purpose of reducing vascular complications in patients undergoing invasive cardiovascular procedures via the femoral artery approach Patel et al 2010 Circ 122:1882
