Sonography of the Liver-P1.flv
This movie illustrates a duplex ultrasonographic examination of a native arteriovenous fistula (anastomosis in the elbow between the brachial artery and the cephalic vein).
A stenosis on the venous run-off (in the perianastomotic area) is depicted.
The flow in the brachial artery proximal to the anastomosis is laminar (Colour Flow mode)
Examination with spectral Doppler analysis reveals a low resistance flow pattern.
This is a normal finding in the feeding artery proximal to the anastomosis and exludes fistula thrombosis. A decrease in the diastolic flow component, is a sign of (impending) thrombosis.
- Just after the anastomosis, the cephalic vein has a narrowed and irregular aspect in B mode imaging.
- In Colour Flow Mode, aliasing (the confetti phenomenon) is seen inside the blood vessel and outside aswell (due to tissue vibration). Those are signs of high and turbulent blood flows and indicative of stenosis.
- With spectral Doppler, high flow velocities are recorded (upto 250 cm/sec). When the blood flow velocities in a suspected area are 2-3 times higher, compared to a non stenosed vascular segment proximal or distal to it, a stenosis is suspected.
Based on 1,2 and 3, this patient has a venous stenosis in the perianastomotic region of his fistula. Whether this stenosis is significant (with danger of losing the fistula) and needs further workup and treatment, can be a matter of debate.
In this case a “watchful waiting” approach seems most appropriate.
Some parameters need to be followed closely in time (pressure at dialysis needles, kt/V, ease of fistula cannulation, volume flow through fistula,…)
When a negative evolution is observed in one of those parameters, further investigation with angiography is necessary to confirm the diagnosis and exclude another problem (fex central stenosis). When the decision has been made to treat , then a surgical treatment is first choice (excision of stenosed segment and proximalisation of the anastomosis) rather then PTA (interventional radiology).

On 17th of October 2009 ECHOGRAFIE.TV organizes the UVAT
hands-on course in Ghent, Belgium.
UVAT means Ultrasound Vascular Acces Training
echografie.tv will present some video's on the use of ultrasound in vascular punctions in preparation of the hands-on course
This video is about ultrasound guided intravenous peripheral line placement.

Echografie.tv organizes on 17th of October 2009
the UVAT ( Ultrasound Vascular Acces Training ) hands-on course
in Ghent, Belgium
echografie.tv will present some video's on the use of ultrasound in vascular punctions in preparation of the hands-on course
This video is about ultrasound guided central venous catheter line placement.
This instructional video is made by the Hennepin County Medical Center, Department of Emergency Medicine
For more instructional video's visit www.hqmeded.com
Prof.P.Michielsen ( Antwerp University, Belgium )explains us how to measure the flow velocity of the Portal Vein.
Good to know:
Normal diameter portal vein: 11mm +/- 2mm
The normal Portal Vein Velocity:
14- 18cm/s
On the sonoworld site (www.sonoworld.com ) you can also find a video on the portal vein ( see lectures )
This video is made by hqmeded.com , High Quality Medical Education
www.hqmeded.com is a great website with a lot of instructional videos, images database, interesting ED images, Dr.Wang Ecg and conferences online.
This particular video shows us how we have to detect ribfractures by ultrasound
echografie.tv made an instructional video on the abdominal ultrasound examination together with
Prof.P.Michielsen from the University of Antwerp (Belgium ) http://www.uza.be/UZA/Home.htm
This video was made for an interuniversital project for Ethiopia
On 21th -24th October 2008 echografie.tv participated at the Annual Meeting of the
MUSOC society(www.musoc.com) in Buenos Aires (Argentina )
In this video Dr.Marnix Van Holsbeeck (Belgium ) explains us how to perform an ultrasound examination of the shoulder
You can also have a look at
www.sonoworld.com .
In a 'How to' video which you can find in chapter 'lectures'
Dr.Bouffard explains you the same procedure
This video , about the use of ultrasound in the diagnosis of retinal detachment, is made by www.emrap.tv.
Emrapt.tv is a great website showing topics about emergency medicine.
