Cord Hemangioma Complicated by Umbilical Vein Rupture; What We Missed on Color Doppler

Umbilical cord hemangiomas are rare tumors of the umbilical cord. Doppler ultrasound has been shown to be useful in the diagnosis of cord hemangioma and evaluation of arterial blood flow through the mass. In this study, we present a 28-year-old pregnant woman with an umbilical cord mass with solid and cystic components. She was followed with weekly umbilical artery (UA) Doppler ultrasound, but the fact that the umbilical vein (UV) ran in the wall of the mass was not noted prospectively. At the time of placental delivery, the cystic component of the mass ruptured tearing the UV causing significant bleeding. The case illustrates the importance of using Doppler ultrasound to both look for UA compromise and to map the UV location through the entirety of the cord.

Epinephrine and norepinephrine injected intravenously into pregnant ewes produced a prompt increase in maternal arterial pressure but a significant and sustained decrease in uterine arterial blood flow. Angiotensin injected intravenously into pregnant ewes produced a prompt increase in maternal arterial pressure (similar to epinephrine and norepinephrine) and an increase in uterine arterial blood flow. In the doses used, epinephrine, norepinephrine and angiotensin injected intravenously into pregnant ewes produced no significant observable effects on the arterial pressure and blood flow in the umbilical cord on heart rate in the fetus. Epinephrine and norepinephrine injected in the umbilical vein of lambs in utero produced a prompt and significant rise in umbilical arterial pressure and umbilical arterial flow only when large doses (five times effective adult doses/kg body weight) were used. Effective adult doses (kg body weight) injected into lambs in utero produced no significant change in arterial pressure or blood flow in the fetus. Angiotensin injected intravenously into lambs in utero produced no significant change in arterial pressure or blood flow in the umbilical cord. Vasoactive drugs injected into the mother on into the fetus did not appear to cross the placenta in either direction in physiologically effective amounts.

The haemodynamic effects of the selective 5-HT1-like agonist GR43175 have been compared with that of ergotamine in anaesthetized cats. Both GR43175 (30–1000 μg/kg intravenously) and ergotamine (0.3–30 μg/kg intravenously) caused a dose-dependent reduction in the proportion of cardiac output passing through arteriovenous anastomoses (AVAs). However, unlike GR43175, the effect of ergotamine (30 μg/kg intravenously) was associated with marked increases in diastolic blood pressure and total peripheral resistance. In further studies, the effect of GR43175 on the distribution of blood flow within the carotid bed has been examined. GR43175 caused a reduction in total carotid arterial blood flow which was entirely due to a reduction in flow through carotid AVAs. These results demonstrate that GR43175, unlike ergotamine, has a highly selective vasoconstrictor action on AVAs within the cranial circulation of anaesthetized cats. Such a mechanism may be important in its antimigraine activity.

Testicular Blood Flow

Varicocele, a vascular event, is associated with infertility due to testicular damage that causes abnormal spermatogenesis in males. The goal of this study is to ascertain the diagnostic significance of scrotal color Doppler ultrasonography (CDUS) by measuring peak systolic value (PSV) and resistive index (RI) of the arteries supplying blood to the testis and their association with semen quality attributes. Sixty prospective patients (age: 20-50 years) undergoing microsurgical varicocelectomy at a teaching hospital were included in the study. Semen parameters and CDUS were recorded and testicular blood flow was determined as PSV and RI of subcapsular artery and intraparenchymal artery of the testes. Nonparametric statistics was applied to test the correlation/association of the semen quality with the PSV, RI, and other variables. Results revealed a significant negative correlation (r = -0.28; p < 0.05) between progressive motility of spermatozoa and resistive index of the intraparenchymal arterial blood flow. Furthermore, it was noticed that the progressive motility of spermatozoa was tended to be negatively correlated (r = -0.236) with resistive index of subcapsular arterial blood flow. In conclusion, this study has revealed that progressive motility of sperms has correlation with the intraparenchymal blood flow of testes. The progressive motility of sperms could be correlated with RI of testicular blood flow. The apparent lack of association between diameter of varicocele vein and semen quality signifies the need of investigating some other factors that may be involved in pathogenicity of varicocele. The diagnostic value of CDUS may be carefully interpreted and clinically correlated in assessment of severity of varicocele.
