Background And Purpose: Ischemic strokes (IS) occur also in young adults and despite an extensive work-up the cause of IS remains very often cryptogenic. Thus, effectiveness of secondary prevention may be unclear. We aimed to analyze a relationship among vascular risk factors (VRF), clinical and laboratory parameters, outcomes and recurrent IS (RIS) in young cryptogenic IS (CIS) patients.
Subjects And Methods: The study set consisted of young acute IS patients < 50 years enrolled in the prospective HISTORY (Heart and Ischemic STrOke Relationship studY) study registered on ClinicalTrials.gov (NCT01541163). All analyzed patients underwent transesophageal echocardiography, 24-h and 3-week ECG-Holter to assess cause of IS according to the ASCOD classification. Recurrent IS (RIS) was recorded during a follow-up (FUP).
Results: Out of 294 young enrolled patients, 208 (70.7%, 113 males, mean age 41.6 ± 7.2 years) were identified as cryptogenic. Hyperlipidemia (43.3%), smoking (40.6%) and arterial hypertension (37.0%) were the most frequent VRF. RIS occurred in 7 (3.4%) patients during a mean time of FUP 19 ± 23 months. One-year risk of RIS was 3.4% (95%CI: 1.4-6.8%). Patients with RIS were older (47.4 vs. 41.1 years, p = 0.007) and more often obese (71.4 vs. 19.7%, p = 0.006), and did not differ in any of other analyzed parameters and VRF. Multivariate logistic regression analysis showed obesity (OR: 9.527; 95%CI: 1.777-51.1) and the previous use of antiplatelets (OR: 15.68; 95%CI: 2.430-101.2) as predictors of recurrent IS.
Conclusion: Despite a higher presence of VRF in young CIS patients, the risk of RIS was very low. Obesity and previous use of antiplatelet therapy were found the only predictors of RIS.

Acute ischemic stroke, a medical emergency caused by reduced cerebral blood flow, results in brain cell damage. While commonly associated with older individuals, strokes can also occur in young and middle-aged adults, posing significant socio-economic and health challenges due to the long-term impact of the condition. This poses significant socio-economic and health challenges because stroke is a leading cause of disability and mortality.

Unlabelled: Right-to-left shunt may be a cause of paradoxical embolization (and cryptogenic cerebral ischemic events). Patent foramen ovale and pulmonary arterio-venous malformations are the most common cause of paradoxical embolization; however, some rare cardiovascular lesions may cause a right-to-left shunt with consequent paradoxical embolization. We describe a case of a young child with superior sinus venosus atrial septal defect who underwent surgical closure and developed a cryptogenic cerebral ischemic attack due to a rare cause of paradoxical embolization, during a long-term follow-up.

The carotid web represents a specific type of fibromuscular dysplasia that primarily affects the intimal layer and is considered a high-risk factor for cryptogenic ischemic stroke. There is still debate regarding the ideal diagnostic imaging for carotid webs. Computed tomography angiography (CTA) is the preferred method in most studies; however, digital subtraction angiography (DSA) has been proven to offer great-quality images for diagnosing and evaluating the carotid web.

Article Synopsis
- Cryptogenic stroke (CS) accounts for about 25% of ischemic stroke cases, often linked to patent foramen ovale (PFO), which can lead to paradoxical embolism; the study assesses the effectiveness of transcranial Doppler (TCD) ultrasound in detecting PFO compared to transesophageal echocardiography (TEE).
- In a study of 110 CS patients, TEE identified PFO in 44.5% of cases while TCD accurately detected right-to-left shunt in 85.7% of these confirmed cases, showing TCD's high sensitivity (85.4%) and specificity (88.5%).
- The results suggest TCD can be a valuable noninvasive
