Summary
Patent foramen ovale (PFO) is linked to cryptogenic stroke. This review examines evidence for PFO treatments, including percutaneous closure, to guide management decisions.
Area of Science:
- Cardiology
- Neurology
- Vascular Medicine
Background:
- Patent foramen ovale (PFO) is increasingly associated with cryptogenic stroke.
- Current treatments include antiplatelets, anticoagulation, and PFO closure.
- Treatment decisions are based on clinical factors and shunt characteristics, but evidence is debated.
Purpose of the Study:
- To analyze the role of PFO in cryptogenic stroke.
- To review available evidence for optimal patient management.
- To provide diagnostic and therapeutic recommendations for PFO-related stroke.
Main Methods:
- Literature review of studies on PFO and cryptogenic stroke.
- Analysis of clinical risk factors and shunt characteristics.
- Evaluation of current therapeutic options and their evidence base.
Main Results:
- A strong association exists between PFO and cryptogenic stroke.
- Risk stratification involves patient age, hypercoagulability, stroke history, PFO size, shunt magnitude, and atrial septal aneurysm.
- There is a lack of consensus on optimal treatment, with some approaches lacking clinical evidence.
Conclusions:
- PFO is a significant factor in cryptogenic stroke etiology.
- Evidence-based recommendations are needed for PFO management.
- Further research is required to establish definitive treatment guidelines.

The Arch of Aorta
The coronary arteries, originating from the ascending aorta, bifurcate from two sinuses located within the ascending aorta. Positioned just above the aortic semilunar valve, these sinuses house essential aortic baroreceptors and chemoreceptors, crucial for maintaining cardiac function. The left coronary artery and the right coronary artery branch off from the left posterior and anterior aortic sinuses, respectively.

Hemorrhagic Stroke ll: Pathophysiology
A hemorrhagic stroke develops when a cerebral blood vessel ruptures, allowing blood to escape into the surrounding brain tissue, as in intracerebral hemorrhage (ICH), or into the subarachnoid space, as in subarachnoid hemorrhage (SAH). Because the skull is a rigid compartment, the sudden presence of extravascular blood rapidly increases intracranial pressure and compresses adjacent neural structures, leading to immediate tissue injury and impaired cerebral perfusion.Mass Effect and Primary...
Ischemic Stroke ll: Pathophysiology
An ischemic stroke occurs when a cerebral blood vessel becomes obstructed, most often by a thrombus or embolus, interrupting the delivery of oxygen and glucose to brain tissue. Because neurons rely on continuous aerobic metabolism, energy failure begins within minutes of reduced perfusion. The region receiving the least blood flow becomes the infarct core, an area of irreversible cellular death. Surrounding this core lies the penumbra, a zone of hypoperfused but still viable tissue that is...
Cerebral Edema ll: Pathophysiology
Vasogenic edema is a major form of cerebral edema characterized by abnormal accumulation of fluid in the brain’s extracellular space due to disruption of the blood–brain barrier (BBB). The BBB is a specialized structure composed of endothelial cells connected by tight junctions, supported by astrocytic endfeet and a basement membrane. Under normal conditions, it tightly regulates the movement of ions, proteins, and solutes between the bloodstream and brain parenchyma. When this barrier loses...
