Vascular Surgery Unit first to use the INARI ClotTReiver on east coast

Northern Health’s Vascular Surgery Unit, led by Mr Iman Bayat, Clinical Lead for Complex Venous Service, is the first vascular team on the east coast of Australia to use an innovative new device to perform deep venous thrombus (DVT) removal in a patient.

Mr Bayat says he is delighted by the outcome and has been closely following the new technology that uses the INARI ClotTreiver device in international literature for the past two years.

“I am pleased to announce that this was the first use of this technology on the east coast of Australia, with the first one performed in Perth. This device is a great tool that we now have in the Vascular Surgery Unit at Northern Health, and it will benefit many patients in the future,” he said.

The INARI ClotTreiver device was approved by the Therapeutic Goods Administration (TGA) in late 2022 and is an over-the-wire system designed to capture and remove large clot burden from veins, treat in a single session, eliminate the need for thrombolytics and eliminate extended stays in the Intensive Care Unit (ICU).

Mr Aman Pillay was the patient at Northern Health who was treated for DVT with the new device.

In March 2023, Mr Pillay presented with an extensive Iliofemoral DVT case. He suffered symptoms such as severe swelling, pain in the left groin and difficulty walking. Initially he opted for conservative management, however after discharge, his symptoms worsened, and he was readmitted two days later.

Following his readmission, Mr Pillay’s case was reviewed by Northern Health’s New Technology Committee, and the Vascular Surgery Unit team offered Mr Pillay treatment using the new technology, and in turn, successfully removed the thrombus later that month.

“The large thrombus was successfully removed by using the new device and without the use of thrombolytic medication, reducing the risk of severe bleeding. The surgery was completed in a single procedure, being the second advantage of this new technology. This technology allows us to remove large central clots up to several weeks old, which was much more difficult to achieve with our previous tools,” said Mr Bayat.

Mr Pillay said he opted for the new technology because it was more advanced and carried less risks compared to the other more traditional clot removal procedures.

“The pain I was having in my groin area was immediately gone after the procedure. I was able to walk, limp free, three to four days after the surgery. I saw my surgeon two weeks after the procedure and by that time, my leg returned to its normal size, I had no pain or discomfort and I felt back to normal,” said Mr Pillay.

The Vascular Surgery Unit has since performed the same procedure on two more Northern Health patients with large clots in the central abdominal veins and the subclavian vein. The use of the INARI ClotTreiver device for removal of a large clot in the subclavian vein was the first use of the device for this particular indication in Australia.
