Incidence of femoral artery false aneurysms

C Ilsley; personal communication

Femoral access


• 45 year old women– Moderate obesity

– Elective catheterisation – RFV/RFA

• Major retroperitoneal haemorrhage– CT scan; 6 unit transfusion

– Discharged on day 6

• Readmitted on day 9– RCFA false aneurysm

– Doppler, CT, thrombin injections

• Discharged day 13

Radial access: just another artery?History of transradial catheterisation

• 1964

– Campeau, Montreal Heart Institute

– Cut-down on proximal RRA

• 1970/80’s

– Percutaneous approach

– Axillary > Femoral > Brachial

• 1989

– Percutaneous transradial coronary angiography/PTCA

Radial access: just another artery?Why bother?

• Pre-Colombian

– Aspirin

– Persantin

– Warfarin

– Dextran

– 8-9F sheaths

– 1 week in hospital

– No closure devices

– 10% bleeding

– 5-10% SAT

• Post-Colombian

– Aspirin

– Clopidogrel

– 6F(5F) sheaths

– day case/23 hours

– Closure devices

– <1% bleeding

– <1% SAT

Radial access: just another artery?ACCESS Study

• Randomised comparison of different access sites

• Experienced operators

• No difference in procedural or fluoroscopy times

Radial access: just another artery?Carafe Study

• Randomised

• Two experienced

operators

• ~50% follow-on PCI with

closure devices for

femoral cases

• Radial groups

– Reduced pain

– Earlier ambulation and

discharge

– Lower costs

CCVI 2001; 54: 202-3. Massy, France

Radial access: just another artery?Difficult coronary anatomy

• LIMA

– LRA is access site of choice

– Specific catheters to approach from RRA

• RIMA

– RRA is access site of choice

• Anomalous origin of RCA from L sinus of valsalva

– Series of case reports

– RRA appears to be access site of choice

• Saphenous vein grafts

– Avoid during initial experience

Radial access: just another artery?Comparison with closure devices (1)

Radial access: just another artery?Potential effect on interventional activity

• Elective day case PCI

– Reduced costs compared to groin closure

– No failed haemostasis

– Convert beds to reclining chairs

• In-patient PCI programme

– Reduced bed utilisation

– Fewer complications

– Reduced LOS
