Maintain Long-Term Vessel Patency - Merit WRAPSODY

Case Review 1

Treatment of Left Subclavian Vein Occlusion From a Large Sheath in the Upper Arm with a 16mm Diameter WRAPSODY™

DR. MATTHEW GIBSON

Dr Matthew Gibson - Merit WRAPSODY - Clinical Case ReviewInterventional Radiologist
Royal Berkshire Hospital, Reading, UK

CLINICAL HISTORY

An 85-year-old male patient on haemodialysis for 15 years with swollen left arm and reduced AV circuit competence. The image below shows a clinically significant subclavian stenosis.

Clinically significant subclavian stenosis - Merit WRAPSODY

RESULTS

The WRAPSODY demonstrated good apposition (no endoleak). The inflow and outflow showed no impingement on the lumen (device wide open).

Post operatively, the oedema in the patient’s left arm reduced dramatically. The dialysis flow rates improved to enable effective treatment.

Dr Huant - Merit WRAPSODY - Clinical Case ReviewInterventional Radiologist
King’s College Hospital, London, UK

CLINICAL HISTORY

A 56-year-old male patient on haemodialysis for 5 years with an history of eight previous venoplasty procedures to treat recurrent left subclavian vein stenosis, presented with a severe arm, face, and neck swelling, as shown in the image below.

56-year-old male patient on haemodialysis for 5 years - Merit WRAPSODY

RESULTS

The final venogram showed good angiographic result with no complication.

The sheaths were removed, and haemostasis was achieved with purse string suture at fistula puncture site and compression to groin puncture site. A CT scan was performed 7 days post-implantation, which showed a patent and well positioned WRAPSODY, minimal distal angulation to the course of the vein without significant stenosis.

Treatment of a Cephalic Arch Stenosis with WRAPSODY™

DR. TOBIAS STEINKE

Dr Tobias Steinke - Wrapsody Case StudyVascular Surgeon
Schön Klinik, Düsseldorf, Germany

CLINICAL HISTORY

A 42-year-old female patient with ESRD with an history of multiple reinterventions due to recurrent central vein stenosis presented with a dysfunctional left basilic AV fistula with an increasing symptomatic arm swelling due to a subtotal stenosis of the subclavian vein at the junction of the brachiocephalic vein.

RESULTS

The sheath was removed, and hemostasis was achieved using a purse string suture.

CLINICAL HISTORY

A 61-year-old male patient on haemodialysis for 12 months presented with a failed AV fistula caused by a clinically significant stenosis of the left brachiocephalic vein promoted by previous numerous ECG leads, as shown in the image to the right.

WRAPSODY™ (12mm x 60 mm) positioning & Post WRAPSODY implantation

RESULTS

The final venogram showed good angiographic result with no complication.

Reflux was observed into the left internal jugular vein. It is concluded that this reflux was not caused by back pressure generated from the outflow of the cell impermeable, more the capacious vessel ‘siphoning’ a small volume of contrast whilst still dilated.

The sheaths were removed, and hemostasis was achieved with compression to groin puncture site.
