Methods One hundred cases of vertigo caused by cerebellar infarction at the recovery stage were randomized into a scalp acupuncture group and a conventional acupuncture group. In the scalp acupuncture group, on the basis of the routine drug therapy, the electric stimulation was applied to the balance area and vertigo-auditory area of scalp acupuncture. In the conventional acupuncture group, on the basis of the routine drug therapy, the conventional acupuncture was supplemented. The treatment was given once a day, 6 treatments made one session. The clinical efficacy was assessed after 4 sessions of treatment. The transcranial Doppler ultrasonography （TCD） was adopted in the scalp acupuncture group to observe the changes of the mean blood flow velocity （Vm） of the anterior cerebral artery （ACA）, middle cerebral artery （MCA） and posterior cerebral artery （PCA） before and after treatment. Results After treatment, the total effective rate was 90.0% （45/50） in the scalp acupuncture group and was 68.0% （34/50） in the conventional acupuncture group, presenting the statistically significant difference in comparison （P0.05）. After treatment, Vm of ACA and MCA was increased apparently as compared with that before treatment in the scalp acupuncture group. Conclusion The electric stimulation at the balance area and vertigo-auditory area of scalp acupuncture achieves the apparent efficacy on vertigo caused by cerebellar infarction at the recovery stage and improves obviously brain blood circulation. It is significant to promote this therapy in clinical practice.展开更多

Thus, TCM is distinct from coronary artery disease （CAD） and acute myocardial infarction （AMI）. However, substantial evidence for co-existing CAD in some TCM patients exist. Herein, we take this associa-tion one step further and present a case in which the patient simultaneously suffered from AMI and TCM, and in which we believe that a primary coronary event triggered TCM. An 88-year-old female presented with chest pain. Echocardiography revealed apical akinesia with hypercontractile bases. An occluded diagonal branch with suspected acute plaque rupture was identified on the angiogram, but could not explain the extent of akinesia. Cardiac function recovered completely. Thus, this patient adhered to current diagnostic criteria for TCM. TCM is a well-known complication for other conditions associated with somatic stress. It is therefore intuitive to assume that AMI, which also associates with somatic stress and elevated catecholamine, can cause TCM. Our case illustrates that TCM and AMI may occur simulta-neously. Although causality cannot be conclusively inferred from this association, the somatic stress associated with AMI may have caused TCM in this patient.展开更多

The computed tomo- graphy angiogram (CTA) of the thorax, performed without cardiac gating, was misinterpreted as normal. In retrospect, an overlooked extravasation of contrast material lateral to the aortic root was detected on non-gating magnetic resonance angiography (MRA). Exploration of the aortic root revealed an unsuspected horizontal intimal tear of the left sinus of Valsalva with limited extramural hematoma. The presence of an otherwise silent intimal tear on preoperative imaging studies makes the overall management more problematic. For example, initiating early broad empirical anticoagulants or fibrinolytics therapy to treat the accompanied myocardial infarction may extend the tear into a full life-threatening aortic dissection, tamponade or rupture. We highlight many of the difficulties associated with the diagnosis and treatment of limited sinus tear when aortic root aneurysm is presenting with cryptogenic STEMI. Accurate morphologic characterization of intimal tear would be best defined with either an electrocardiogram-gating CTA or MRA imagings. These non-invasive tests are needed to make appropriate management decisions. Depending on other pathologic components of aortic root, cusps and the commissural geometry, sinus tear is a critical component for the overall treatment plan and it shifts the surgical intervenetion from valve-sparing operation, commissural resuspension and leaflet repair to composite aortic root replacement (modified version of the Bentall procedure).展开更多
