Variação do IMT mais forte que o IMT final?

Intima Media Thickness Variability (IMTV) and its association with cerebrovascular events: A novel marker of carotid atherosclerosis?

.
.
Results: In all cases the ROC area under the curve was higher for IMTV than IMT. There was a statistical significant association between IMTV and cerebrovascular events (P=0.018), but no relationship between IMT and events. The results for inter-observer variability showed a systematic error between 0.04 mm and 0.08 mm. In the Person Rho correlation analysis in no case a statistical association between IMT and symptoms was detected whereas in 2 cases (observer 1 and observer 2), a statistically significant association between IMTV and symptoms was found.
Conclusions: Data of this preliminary study suggest that IMTV may represent a powerful method to assess carotid atherosclerotic disease with a significant association to cerebrovascular events.

Artigo mostra relação da variabilidade do IMT no modo automático mais significativo que o próprio IMT.

Estudo preliminar mas interessante.
Cansamos de ver IMT rugosas que parecem cascas de nozes mas são abaixo de 1,0 mm.

As jugulares não serão mais esquecidas.

Internal Jugular Vein Valve Incompetence Is Highly Prevalent in Transient Global Amnesia

.
.
Results— Valve insufficiency was found in at least one jugular vein in 113 of 142 patients with Transient Global Amnesia (79.5%) and in 10 of 40 controls (25.0%), P<0.01. The right side was affected more often than the left side, P<0.01, and 26.8% of the patients had bilateral incompetence.
.
Conclusions— Patients with TGA have a high prevalence of IJV valve insufficiency. This finding may have pathophysiologic implications. Doppler evaluation of the IJVs with dynamic maneuvers may help in the evaluation of this usually benign condition.

O mais interessante do ultrassom é sua aplicação ilimitada.

A Jugular foi ignorada nos exames vasculares cervicais por anos. Agora vemos fortes evidência da presença de refluxo jugular implicando doenças comuns.
