Growth in Treatment of Acute Stroke

Drawn from Report #C310, “Emerging Global Market for Neurointerventional Technologies in Stroke, 2014-2019”, published by MedMarket Diligence, LLC.

Therapeutic management of stroke encompasses a broad scope of prophylactic, palliative and curative treatment modalities that are typically employed in some combinations during the preventive, acute and rehabilitation phases of stroke-related care delivery.

Historically, prevention has been universally regarded as the best form of medicine for dealing with any disease. This old wisdom is especially true in management of acute stroke, which represents a catastrophic event with a largely predetermined clinical progression and outcome that stem from the patient’s preexisting pathologies and can be only marginally altered with available emergent therapies.

The commonly accepted, current strategy of primary and secondary stroke prevention is focused on elimination or remedying of the modifiable risk factors that have been shown to create a general predisposition or directly contribute to the onset of acute cerebral ischemia or/and hemorrhage.

Within the context of general population, this strategy is targeting alleviation of certain lifestyle risk factors (such as smoking, obesity, physical inactivity, excessive alcohol consumption, drug abuse, high-fat diet etc.), which could contribute to the development of cardiovascular and other pathologies associated with increased propensity to stroke.

In patient caseloads with preexisting medical conditions (AFib, mechanical prosthetic valves, recent AMI, stoke or TIA, hypertension, diabetes, etc.) which are characterized by a high risk of adverse vascular events potentially leading to stroke, preventive strategy is focused on reducing such risks via a strict control and monitoring of corresponding hemostatic and hemodynamic parameters.

Finally, in persons with diagnosed cerebrovascular pathologies (high grade carotid stenosis, intracranial aneurysms and AVMs) the first line preventive therapy involves their repair or eradication, when technically possible.

The scope of FDA-approved medical and interventional modalities commonly employed in preventive management of stroke includes oral anticoagulation, antiplatelet, and lipid-lowering drug therapies, cerebral aneurysm and AVM repair surgery, carotid endarterectomy, stereotactic radiosurgery, as well as endovascular embolization of intracranial aneurysms and AVMs, carotid artery stenting with embolic protection, left atrial appendage closure, along with  rarely used and likely to be abandoned intracranial stenting.

In contrast to causes-oriented therapies used in stroke prevention, therapeutic modalities employed in the emergent management of acute stroke are focused almost exclusively on patients’ cardiopulmonary and hemodynamic support and ad hoc containment of dangerous complications and corresponding brain damage associated with stroke.

Among the life-threatening complications that commonly accompany acute cerebral hemorrhage or ischemia are cerebral edema; hydrocephalus; brain stem compression; vasospasm and pulmonary embolism.

Management of the aforementioned acute complications relies on a few proven treatment regimens, including (but not limited to):

  • medical therapy and catheter-based ventricular drainage of cerebrospinal fluid to control intracerebral pressure in patients at risk of edema, hydrocephalus or brain stem compression;
  • hypertensive hypervolemic hemodilution (or “triple-H” therapy) to treat ischemic neurological deficit from vasospasm following subarachnoid hemorrhage;
  • subcutaneous anticoagulation (with heparins or heparinoids) for prophylaxis of pulmonary embolism (which accounts for approximately 10% of deaths following stroke); and
  • elective hypothermia for temporary salvaging brain cells from necrosis due to hemorrhagic trauma or acute ischemia (although the latter technique has not been proven efficacious in clinical trials and was not endorsed in the latest, 2007 versions of the AHA hemorrhagic and ischemic stroke guidelines).

The currently available curative treatment options for acute stroke are limited to intravenous t-PA therapy (which has about 30% efficacy and is indicated for a very narrow cohort of eligible ischemic stroke patients only), investigational intra-arterial thrombolytic therapy, transcatheter cerebral thrombectomy (in patients who did not qualify for or failed t-PA therapy), and emergency craniotomy-based or endoscopic removal of stroke-related hematoma (which carries a 50% to 80% risk of mortality and is reserved for rapidly deteriorating young patients with large lobar hemorrhages).

Rehabilitation phase of stroke management relies on general physiotherapeutic techniques commonly used in patients with various physical and neurological disabilities. Prophylactics of recurrent cerebrovascular events in stroke survivors employs medical and interventional regimens referred to in the overview of primary and secondary stroke prevention.

Coronary Stent takes largest total market share to 59.6%

The global trend is for a continued decrease in the number of CABG procedures and an increase in the number of percutaneous coronary intervention procedures. Typically about 90% of all percutaneous coronary intervention procedures use a coronary stent in the developed economies with approximately 75% of all procedures that use stents do so with drug-eluting stents (DES) and this percentage continues to increase.

For the vast majority of cases of coronary artery disease, the treatment options are typically limited to angioplasty alone or with stents or coronary artery bypass grafting. Aside from the advent of new device and equipment technologies to perform coronary artery bypass via catheter or otherwise in minimally invasive formats (such as minimally invasive direct coronary artery bypass, or MIDCAB), the market for the treatment of coronary artery bypass is largely represented by interventional cardiology, comprised of the following products:

  • Global sales of coronary guide wires, balloon dilatation catheters, guiding catheters and accessories
  • Stents
  • Vascular closure devices

See the White Paper on Coronary Stents (see the “DOWNLOAD” button) and the associated report, “The Future of Coronary Artery Disease Medical Devices to 2021“, published by Smithers Apex.

Trend in Endovascular Acute Stroke Management Procedures

Therapeutic management of stroke encompasses a broad scope of prophylactic, palliative and curative treatment regimens that are typically employed in some combinations during the preventive, acute and rehabilitation phases of stroke-related care delivery.

Over the past two decades, one could witness the advent and significant expansion of the neurointerventional armamentarium targeting management of acute stroke. In mid-1990s, endovascular coiling embolization tools and techniques for treatment of cerebral aneurysms and AVMs (arterio-venous malformations) were introduced as a less invasive alternative to craniotomy-based surgery in primary prevention of hemorrhagic stroke. Several years later, these techniques were supplemented with coil-containing stents, which enabled treatment of large, giant, and wide-neck aneurysms. The latter was followed by the launch of stent-based flow diversion systems, which allowed clinicians to hemoisolate such aneurysms without tedious and risky coil packing of the rupture-prone aneurysmal sac.

In primary ischemic stroke prevention, development of embolically-protected carotid stenting and left atrial appendage closure techniques provided clinicians with an option of using non-inferior transcatheter tools instead of customary surgical interventions.

Finally, a recent launch of the novel stent-based cerebral thrombectomy systems manifested a qualitative breakthrough in emergent treatment of acute cerebral ischemia, where marginally effective and severely caseloads restrictive intravenous tPA therapy represented the only available therapeutic option.

Presently, endovascular techniques are increasingly seen and used by practicing clinicians as preferred therapeutic modalities in prophylaxis and treatment of acute stroke and are likely to expand their role in the years to come.

Cerebral Endovascular Embolization Cases, Procedures Growth

In 2014, endovascular embolization techniques were employed in approximately 90.5 thousand cerebral aneurysm and AVM repair procedures worldwide, of which aneurysm targeting interventions accounted for about 89.2%, with the rest contributed by AVMs hemoisolation.

During the forecast period, the total global volume of transcatheter neurovascular embolization procedures is projected to grow 4% per annum to an estimated 109.9 thousand interventions in the year 2019. The largest absolute and relative gains in cerebral embolization procedure volumes are expected in the largest Asian-Pacific states (mostly China) and the Rest-of-the-World, where low relative usage of endovascular techniques (30-35% versus 65-75% in the U.S. and Europe) will continue to support their increasing penetration of clinical practices and serve as the primary locomotive of growth in the corresponding global product market.

Largely mature U.S. and West European market geographies are likely to register considerably more modest advances in cerebral embolization procedure volumes.  Below is compared the growth rates to 2019 for cerebral endovascular embolization in the major Asia-Pacific countries (Japan, India, and China) to the same in Western Europe.
