Grading Right-to-Left Shunt With Transforaminal Doppler: A Valid Approach in Patients With Cryptogenic Stroke.

Background And Purpose: Right-to-left shunt (RLS), usually related to a patent foramen ovale (PFO), is an important cause of cryptogenic stroke (CS) in young patients. Transcranial Doppler (TCD) with an agitated saline bubble study is a highly sensitive modality for RLS diagnosis using a transtemporal approach (TTD). However, a minority of patients have insufficient temporal bone windows.

Clot migration in patients treated with tenecteplase versus alteplase before mechanical thrombectomy.

Introduction: This study aimed to describe and analyze the rate of clot migration of vessel thrombosis to distal segments in patients with acute ischemic stroke (AIS) who received intravenous thrombolysis (IVT) with tenecteplase (TNK) and alteplase (ALT) before mechanical thrombectomy (MT). In addition, we aimed to determine the relationship between thrombus migration and functional prognosis.

Methods: This study followed the STROBE reporting guidelines.

[Descriptive study of the alterations in neuroimaging tests in patients with headache in an outpatient setting].

Introduction: Available studies provide limited guidance on the use of neuroimaging in patients with headache in the outpatient setting. The aim of this study was to describe and analyse the frequency and the percentage of neuroimaging abnormalities in patients evaluated for headache in a neurology clinic, as well as to determine which red flags are most commonly associated with these abnormalities.

Patients And Methods: We conducted an observational, descriptive and cross-sectional study of a series of patients with headache from the neurology department of the Hospital Universitario de Mostoles who underwent a neuroimaging test.
