ABSTRACT
Arteriovenous fistulae of the upper limbs are rare in the pediatric population. They can be caused by trauma, needle puncture, or other iatrogenic injuries. A 5-year-old boy presented with progressive swelling of the right hand, which was initially misinterpreted as an arteriovenous malformation based on his noninvasive diagnostic work-up. He was ultimately diagnosed with right brachiocephalic arteriovenous fistula by catheter angiography, and the fistula was then successfully treated with coil embolization. This article describes the relevant imaging findings and potential implications for treatment.
ABSTRACT
OBJECTIVE: To establish a multiplex PCR point mutation screening technique for the genotyping of CYP2C19. METHODS: Deoxyinosine multiplex-polymerase chain reaction (PCR) primers (DMPs) were designed to detect simultaneously CYP2C19*1,*2,*3 alleles in one PCR tube. RESULTS: The above technique could detect the genotypes of CYP2C19*1, CYP2C19*2 and CYP2C19*3 successfully. And the results were completely consistent with those of DNA sequencing. CONCLUSION: A novel screening technique of multiplex PCR point mutation is successfully established. With the advantages of high specificity, convenient handling, fast completion and low cost, it provides a reasonable and reliable detection method for basic researches and personalized medicine.
