Role of 3D power Doppler sonography in early prenatal diagnosis of Galen vein aneurysm.
Vein of Galen aneurysm malformation (VGAM) is a rare congenital vascular anomaly. Although the cause of VGAM remains to be elucidated, the current hypothesis is persistence of the embryonic vascular supply, which leads to progressive enlargement and formation of the aneurysmal component of a typical VGAM. Here, we present a 36-year-old woman at 23 weeks' gestation (gravida 3, para 2) who was ev...
متن کاملCorrelation between Endometrial Parameters in Doppler Sonography and Success Rate of Implantation in Assisted Reproductive Programs
Background Levels of serum gonadotropins have direct effects on testicular functions and spermatogenesis. Assessment of levels of serum gonadotropins from fathered subjects and infertile patients indicates wide range diversity. In this study, we tried to find out whether the levels of seminal FSH and LH affect the parameters of seminal fluid analysis (SFA) and if there is any correlation betwee...
متن کاملDiagnosis of brain death by transcranial Doppler sonography.
Delays in diagnosis of brain death have definite consequences for the organ retrieval and transplantation process. It is advisable to use accurate diagnostic methods. Transcranial Doppler sonography is a well-accepted technique for diagnosing cerebral circulatory arrest. However, in some cases, the access to the intracranial circulation via the temporal window is difficult. In 43 brain-dead pat...
متن کاملDiagnosis of brain death by transcranial Doppler sonography
The blood flow velocities in the basal cerebral arteries can be recorded at any age by transcranial Doppler sonography. We examined nine children with either initial or developing clinical signs of brain death. Soon after successful resuscitation increased diastolic flow velocities indicated a probable decrease in cerebrovascular resistance; this was of no particular prognostic importance. As s...
متن کاملDoppler sonography diagnosis of cerebrovascular disease.
Sonographic patterns for the Doppler ophthalmic test (DOT) were determined by reviewing the type of graphic record obtained from 25 patients who had undergone angiography. Three principal patterns were identified, depending upon whether there was augmentation (Type 1), diminution (Type 2) or no change (Type 3) in the character of the supraorbital Doppler signal upon temporal artery compression....
