Dundee and US surgeons achieve world-first stroke surgery using robot

Docs from Scotland and the US have accomplished what’s regarded as a world-first stroke process utilizing a robotic.

Prof Iris Grunwald, of the College of Dundee, carried out the distant thrombectomy – the removing of blood clots after a stroke – on a human cadaver that had been donated to medical science.

The professor was at Ninewells Hospital in Dundee, whereas the physique she was working on whereas utilizing the machine was at a college facility.

Hours later, Ricardo Hanel – a neurosurgeon in Florida – used the know-how to hold out the primary transatlantic surgical procedure from his Jacksonville base on a human physique in Dundee over 4,000 miles (6,400km) away.

The group has referred to as it a possible “recreation changer” if it turns into accepted to be used on sufferers.

The medics consider this know-how may rework stroke care, as a delay in accessing specialist therapy can have a direct affect on the probabilities of restoration.

Prof Grunwald stated: “It felt as if we had been witnessing the primary glimpse of the long run.

“The place beforehand this was regarded as science fiction, we demonstrated that each step of the process can already be accomplished.”

The College of Dundee is the worldwide coaching centre of the World Federation for Interventional Stroke Therapy, and is the one place within the UK the place docs can function on cadavers with liquid which mimics human blood circulated within the vessels.

“This was the primary time that we may carry out the entire mechanical thrombectomy process in an actual human physique to indicate that every one steps of the process are doable,” stated Prof Grunwald.

Juliet Bouverie, the chief govt of the Stroke Affiliation charity, advised BBC Information the transatlantic process was “a outstanding innovation”.

She added: “For too lengthy, folks residing in distant and rural areas have been disadvantaged of entry to thrombectomy.

“Robotics like this might rebalance the inequity which exists in stroke therapy throughout the UK.”

Within the experiment, fluid which mimics human blood was utilized in 4 completely different cadavers.

The topics, who donated their our bodies to science, died throughout the previous three years and had been then embalmed.

Each the Dundee and Florida procedures had been carried out final month utilizing robotics from the Lithuanian agency Sentante.

Whereas there have been distant thrombectomies carried out earlier than on a silicon model, a 3D printed replica and on an animal, that is thought to have been the primary process on a human physique.

The group now hope to participate in scientific trials subsequent yr.

An ischaemic stroke happens when an artery is blocked by a clot.

This cuts off blood and oxygen provide to the mind, and mind cells lose perform and die.

The most effective therapy is a thrombectomy, the place a specialist makes use of catheters and wires to take away the clot.

However what occurs when a affected person cannot get to a specialist who can do the process?

Prof Grunwald stated the experiment demonstrated a robotic might be linked to the identical catheters and wires a surgeon would usually use, and a medic who’s with the affected person may merely connect the wires.

The surgeon, in one other location, may then maintain and transfer their very own wires, and the robotic then carries out precisely the identical actions in actual time on the affected person to hold out the thrombectomy.

The affected person could be in a hospital working room, whereas the physician may perform the process utilizing the Sentante machine from wherever – even their very own residence.

Prof Grunwald and Ricardo Hanel may see reside X-rays of the physique within the experiments, and monitor progress in actual time, with the Dundee knowledgeable saying it took solely took 20 minutes of coaching.

Tech giants Nvidia and Ericsson had been concerned within the venture to make sure the connectivity of the robotic.

Dr Hanel stated: “To function from the US to Scotland with a 120 millisecond lag – a blink of a watch – is really outstanding.”

Prof Grunwald, who has received an award from Innovate UK for her work and can be the vp of the World Federation for Interventional Stroke Therapy, stated there have been two most important issues with a normal thrombectomy – a worldwide scarcity of docs who can do it, and therapy will depend on your location.

In Scotland, there are solely three locations sufferers can obtain the process – Dundee, Glasgow and Edinburgh. Should you do not reside there, you need to journey.

Prof Grunwald stated: “The therapy could be very time delicate.

“Each six minutes delay, you’ve got a 1% much less likelihood of getting a great end result.

“This know-how would now present a brand new method the place you are not relying on the place you reside – saving the precious minutes the place your mind is in any other case dying.”

Public Health Scotland said there have been 9,625 ischaemic strokes in Scotland final yr.

Solely 212 – or 2.2% of all sufferers – obtained a thrombectomy, whereas 1,045 folks obtained treatment to burst the clots.

For the remainder of the UK, only 3.9% of all stroke patients obtained a thrombectomy within the yr to March 2024.

“It feels superb,” added Edvardas Satkauskas, the CEO of Sentante, talking to BBC Information from the corporate’s base in Lithuania.

“Generally, the long run is method nearer than we expect.”
