Major ischemic strokes secondary to proximal artery occlusions are responsible for significant morbidity and mortality. Owing to extensive clot burden, these strokes are poorly responsive to intravenous tissue plasminogen activator. The introduction of endovascular therapy, particularly mechanical devices, has resulted in markedly improved recanalization rates of large vessel occlusions. With increasing experience with the Penumbra Stroke System and the 054 reperfusion catheter, there has been further improvement in TIMI 2 and 3 revascularization rates with faster times to vessel opening. The aim of this technical review is to convey various tips and tricks learnt from this experience.

Stroke: Introduction and Types

A stroke is an acute neurological event caused by the sudden disruption of cerebral blood flow, leading to rapid loss of neuronal function. Neurons depend on continuous oxygen and glucose supply, so even brief interruptions can cause irreversible injury within minutes. Strokes are classified into ischemic and hemorrhagic types.Ischemic StrokeIschemic strokes are most common and occur due to arterial occlusion, depriving brain tissue of oxygen and nutrients. This leads to energy failure, ionic...

Hemorrhagic Stroke l: Introduction

A hemorrhagic stroke is an acute neurological event that occurs when a weakened cerebral blood vessel ruptures, allowing blood to accumulate within or around the brain. The sudden release of blood forms a focal hematoma that increases intracranial pressure, displaces neural tissue, and can obstruct cerebrospinal fluid pathways. These effects may be compounded by intraventricular extension of the hemorrhage, cerebral edema, or compression of adjacent structures, all of which contribute to...
