Conclusion OCT

• Interesting technique offering guidance for endovascular treatment of complex lesions

• Its use can result in fairly high success-rate – obviously case dependant

• Early data are encouraging

• No comparative studies published

• Has not really found its place in daily practice

Ultrasound guided endovascular treatmentExperience in Copenhagen

• AV-fistula stenosis more or less ALL treated by USG endovascular therapy in our outpatient clinic since autumn 2017

• > 250 cases done

• Since 2019, 15 selected in-situ vein graft stenosis treated with USG

• Almost all done using L12-3, single linear array, just a few using XL14-3

• Will show examples with XL 14-3

Conclusion Endovascular treatment guided by 3D ultrasound

• New promising technique

• May be useful in

• Guiding arterial puncture – especially in severely diseased vessels

• Guiding passage of complex lesions

• Evaluating result post treatment

• No scientific data exits at present

• Designing study to prove the value …
