RESUMO
We report the diagnosis and treatment of a pregnant woman with acute Stanford type B aortic dissection in the second trimester who underwent thoracic endovascular aortic repair under local anesthesia and later gave birth to a live neonate. The patient was admitted due to acute upper back pain at 27 weeks of gestation, who was diagnosed as acute Stanford type B aortic dissection. Thoracic endovascular aneurysm repair was performed with low radiation dose under local anesthesia. A live neonate was born through cesarean section at 33 +6 gestational weeks due to the flat baseline of the fetal heart monitor, with a birth weight of 1 840 g and Apgar score of 9 at 1 min. The neonate was discharged after a 20-day treatment. During the follow-up of 12 months, the infant grew and developed well, and covered stent was well placed in the mother without leakage in the distal or proximal ends of the stent or any other complications.
RESUMO
Objective To explore brain activity features during the resting state in alcohol dependent individuals,and study the relationship between the brain activity features and alcohol dependent individuals' clinical symptoms.Methods Twenty-four alcohol dependent individuals and 22 healthy control subjects,well matched in gender,age,education and handedness,were enrolled as the alcohol dependent group and control group respectively.AGE 3.0 T MR scanner was used to acquire all the subjects' resting state data. DPARSF software was used to process resting functional MRI data,and then the whole brain fractional amplitudes of low frequency fluctuation (fALFF) data were acquired.Two-sample t test statistical analysis was made to access fALFF difference between the two groups. Results In comparison with the control group,the alcohol dependent group showed reduced fALFF in bilateral medial prefrontal gyrus,right inferior occipital gyrus,left precuneus,left inferior temporal gyrus,and left posterior lobe of cerebellum (0.64-1.69 vs.0.87-1.78,t =- 4.23- - 2.79,P ＜ 0.05 ). fALFF was increased in the alcohol dependent group at the anterior cingulate,bilateral inferior frontal gyrus,right middle frontal gyrus,bilateral insular lobe,bilateral dorsal thalamus ( 0.86-1.82 vs. 0.76-1.58,t =3.56-3.96,P ＜ 0.05 ).Conclusion Alcohol dependent individuals had abnormal activity at the bilateral prefrontal lobe,anterior cingulate,bilateral dorsal thalamus,bilateral insular lobe,left posterior lobe of cerebellum et al,during the resting state,and these abnormal activities might be related with clinical manifestation and pathophysiology.
