Interventions in Acute Stroke – Evolving Trends

Acute stroke management is undergoing a renaissance. An era once marked by therapeutic nihilism has given way to one of renewed hope. Advances in interventional neuroradiology—particularly modern mechanical thrombectomy techniques—along with decompressive craniectomy for cerebral venous thrombosis, and minimally invasive surgical approaches for intracerebral hematomas, are now widely regarded as standards of care. The cover page illustration captures these paradigm shifts, and the evolving techniques that define contemporary management of the three major forms of stroke Figure 1.Figure 1The first row of images demonstrates recanalization of cerebral vessels following mechanical thrombectomy in a patient with internal carotid artery occlusion.1 Mechanical thrombectomy constitutes the most transformative advance in contemporary acute ischemic stroke care and is now firmly established as the standard of care for anterior circulation large-vessel occlusions. The advent of advanced perfusion imaging has broadened patient selection beyond rigid time-based criteria, allowing intervention up to 24 hours in carefully selected patients with salvageable brain tissue. Ongoing refinements in thrombectomy techniques and device technology have enhanced procedural efficiency and clinical outcomes. These include the direct aspiration first-pass technique (ADAPT), combined strategies employing stent retrievers with aspiration catheters and balloon guide catheters, and the introduction of newer third-generation devices such as EmboTrap and Tigertriever. The increasing use of balloon guide catheters, together with advances in navigation and imaging optimization, underscores a shift toward higher first-pass success, improved recanalization rates, and better functional recovery.2 The second row illustrates the role of decompressive surgery in cerebral venous thrombosis (CVT). Findings from the DECOMPRESS-2 study strongly support decompressive surgery as a life-saving intervention in patients with severe, medically refractory CVT complicated by life-threatening intracranial hypertension.3 The third row highlights the role of minimally invasive surgery in the management of spontaneous intracerebral hematoma. Over the past two decades, surgical treatment of spontaneous intracerebral hemorrhage has progressively shifted from conventional open craniotomy toward minimally invasive, image-guided, and fiber-sparing techniques. These approaches aim to achieve effective hematoma evacuation, while minimizing injury to the cortex and subcortical white matter. In supratentorial intracerebral hematomas, particularly deep basal ganglia hemorrhages, minimally invasive endoscopic techniques have shown greatest promise. The MISICH trial outcomes and the ongoing studies such as NESICH further reinforce the value of navigation-guided, parafascicular, fiber-sparing endoscopic approaches, reporting high evacuation rates, low mortality, and favorable functional outcomes.4,5 The illustration in the last row was generated with the assistance of ChatGPT (GPT-4 series, OpenAI). As neuroscientists battling stroke, we can all be optimistic that we are now at the dawn of a new, exciting, and brighter era in the management of acute stroke, both ischemic, and hemorrhagic.
