Background: Duplex Colour Doppler Sonography is gaining increasing popularity for assessment of blood vessels in various disease processes around the world as well as for the surveillance of fetus compromised by intra uterine growth retardation (IUGR) and to assess foetal structural abnormalities and complex disease processes. Materials & methods: This cross sectional study was carried out to observe Doppler wave form in subjects with preeclampsia enrolling 40 subjects with preeclampsia, in the Department of Radiology and Imaging, Dhaka Medical College Hospital, Dhaka, over a period of six months from 20th May 2012 to 19th November 2012. A total number of 40 normal pregnancies were also included for comparison. Peak systolic velocity (PSV), end diastolic velocity (EDV), Resistive index (RI), Pulsatility index (PI) in different groups of study subjects from 24th to 37th weeks were observed and compared for any significant differences. Results: Majority (35% in normal and 37.5% in preeclampsia) of the respondents were found in the age group of 21-30 years. Unpaired t-test revealed no significant difference between mean age between two groups. Among normal group, mean±SD PSV, EDV, PI and RI were 43.94±15.41 cm/sec and 15.51 (±4.93) cm/sec, 1.12±0.0846 and 0.571 (±0.058) respectively. Mean PSV, EDV, PI and RI were 83.19±18.44 cm/sec, 11.86±5.19 cm/sec, 2.497±0.369 and 0.8255±0.087 in preeclampsia group. There was statistically significant (By unpaired ttest) difference in mean Doppler indices between these two groups. It was observed that early diastolic notch was found in 90% subjects with preeclampsia. Early diastolic notch was observed in Doppler wave form in 5% subject with normal pregnancy. Chi-square test showed that there was statistically significant difference in presence of early diastolic notch between normal subjects and subjects with preeclampsia. Conclusions: From the study result it was concluded that Doppler indices with presence of early diastolic notch are reliable indicators for early detection of preeclampsia.

Background Knowing transient vascular perfusion abnormalities of testes after open inguinal herniotomy procedure is essential for the surgeon who is mainly responsible for the patient outcome. Purpose To assess the effect of open inguinal herniotomy procedure on the testicular blood supply in children using duplex ultrasonography (DUS). Material and Methods A prospective observational study included 60 boys (mean age = 9.46 ± 14.46 months; age range = 2 months–6 years) who underwent open inguinal herniotomy operation. Using DUS, the testicular volume, peak systolic velocity (PSV), end diastolic velocity (EDV), and resistive index (RI) were calculated preoperatively and one week, one month, and six months postoperatively. The pre- and postoperative measurements were compared. Statistical analysis was performed using χ2 test, Fisher’s exact test, or Student’s t-test when appropriate. Results On physical examination, the hernias were unilateral in 57 boys and bilateral in three boys. Comparison between testicular volumes preoperatively and postoperatively showed no significant change ( P > 0.05). There was a statistically significant increase of PSV and RI one week and one month postoperatively ( P < 0.0001) but returned to be near to the preoperative values at six months. As regards EDV, there was a slight but non-significant postoperative increase ( P > 0.05) which did not return to the preoperative value. Conclusion The affection of testicular vascularity postoperatively is transient and returns to be near to the preoperative values in the late postoperative period (six months postoperatively). Additionally, no significant change in testicular volume postoperatively.

Haemodynamic Changes

Introduction: Varicocele is among the most frequently encountered, surgically correctable causes of male infertility. Since varicocele is a primary abnormality of testicular vessels, a thorough understanding of haemodynamic changes in the microcirculation of varicocele testis is needed. Objectives: To estimate changes in the microcirculation of varicocele testis and correlate them with symptomatic and semen parameters changes before and after varicocelectomy. Material and methods: This prospective, observational study includes 47 patients of age group 18–40 years who underwent microsurgical varicocelectomy during June 2016 to April 2018 at a tertiary medical institute. Testicular haemodynamic was evaluated using a colour spectral doppler study (PSV-Peak systolic velocity/ESV-End diastolic velocity/RI-Resistive index/PI-Pulsatility index). Semen analysis parameters and testicular blood flow were compared with pre-operative values. Results: RI in the capsular artery of varicocele affected testis, which was 0.61 ± 0.11 (mean ± SD), significantly reduced to 0.56 ± 0.09 (mean ± SD) in post-operative follow-up, indicating improved perfusion. Pre-operative sperm density was noted to be 15.94 ± 7.88 (mean ± SD), which improved to 28.41 ± 10.99, Progressive sperm motility from 33.81 ± 10.88 to 38.32 ± 9.21 and morphology from 36.13 ± 10.68 to 41.43 ± 9.29 on 6-month follow-ups ( p < 0.05). Conclusion: Varicocele testis is associated with altered testicular haemodynamic, which insults spermatogenesis. Microsurgical varicocelectomy with testicular artery and lymphatic preservation leads to correction of this altered haemodynamic state and improves the testicular microcirculation.

Introduction: Cervical region is the commonest area of lymphadenopathy which is easily accessible to ultrasound and Doppler study. The morphological and vascular-architectural differences among various nodal diseases aids in differentiating benign from malignant causes. Methods: The study was done on the 108 patients referred to Department of Radiology andImaging, TUTH for ultrasound of cervical lymphadenopathy who subsequently underwentFNAC examination. Gray scale evaluation for morphology of the nodes along with Doppler evaluation for resistive index (RI), pulsatility index (PI) and Peak systolic velocity (PSV) were done and correlated with FNAC findings. Results: Among the 108 lymph nodes, 24 were proven to be malignant on FNAC. Features such as S/L ratio >0.5, absence of echogenic hilum, and abnormal vascular pattern demonstrated sensitivities of 96%, 92%, and 87%, specificities of 74%, 65% and 77% and positive predictive values (PPVs) of 51%, 43%, and 55% respectively. The cutoff values for RI, PI and PSV were found to be 0.705, 1.34 and 17.5 cm/s with sensitivities of 96%, 96% and 87%, specificities of 95%, 99% and 88% and positive predictive values (PPVs) of 85%, 95% and 70% respectively. Conclusion: Ultrasound findings of S/L ratio, absence of echogenic hilum, abnormal vascular pattern and Doppler indices revealed good sensitivity, specificity, and accuracy in differentiating benign and malignant lymph nodes.

Introduction: Color Doppler Imaging (CDI) is used widely to study retrobulbar circulation. Objectives: To determine the association between progression of diabetic retinopathy (DR) and alterations in retrobulbar arterial circulation using CDI studies. Materials and methods: Prospective observational case series. It is single institutional study of 50eyes of nonproliferative diabetic retinopathy in 50 patients with type II diabetes mellitus. DR was graded according to ETDRS system. Retrobulbar circulation was studied in patients for Peak systolic velocity (PSV), End diastolic velocity (EDV) and Resistive index (RI) in Central retinal artery (CRA), Ophthalmic artery (OA) and Posterior ciliary artery (PCA) using CDI initially and reevaluated after 6 months or later for any change in retinopathy grade and arterial circulation parameters. The patients were grouped as Group I not showing progression of DR and Group II showing progression. The two groups were compared for any significant change in CDI parameters. Results: The baseline resistive indices were higher than normal population. There was significant increase in RI in PCA and CRA in all patients after 6 months. 14 patients (28%) showed progression of DR and 36 (72%) did not show progression of DR. There was no significant association with progression of retinopathy and CDI findings. (p=>0.05). Conclusion: The retrobulbar arterial circulation seems to be affected in all diabetics with DR. The changes appear to be progressive. The CDI findings in arterial circulation however lack predictive power for progression of diabetic retinopathy in non proliferative DR.

Abstract BACKGROUND In a year around 3.5 million preterm deliveries occur in India alone. Some of these babies will require packed cell volume (PCV) transfusion. There is a paucity of robust data on effect of blood transfusions on the cerebral hemodynamic from India. This study was done to see the effect of PCV transfusion on blood flow velocities and resistive index (RI) of anterior cerebral artery (ACA) in stable preterm infants. METHOD A prospective observational study was conducted in a tertiary care hospital in Pune, India. All stable preterm infants (<37 weeks) receiving PCV transfusion were enrolled. USG Doppler study of ACA was done before and after PCV transfusion. Peak systolic velocity (PSV), end-diastolic velocity (EDV) and RI were measured pre and post PCV transfusion. RESULTS Thirty infants were included in the study, with median gestation age of 28.8 [interquartile range {IQR}, 27-30.55] weeks and median birth weight of 970 [interquartile range {IQR}, 869.5-1190] grams. There was a significant decrease in PSV pre and post PCV transfusion - 58.46 (±18.44) cm/sec and 46.34 (±13.93) cm/sec respectively (p value <0.001). Changes in RI and EDV were non-significant.CONCLUSION PCV transfusion significantly decreased PSV, reflecting improved cerebral oxygenation, and decreased cardiac output after correction of anaemia. Laboratory threshold for PCV transfusion in stable preterm infants are not known. USG Doppler study has the potential to provide one of the objective criteria for PCV transfusion in these infants though large scale randomized controlled trials are needed to prove its efficacy.

BACKGROUND : Doppler indices form an integral component of noninvasive evaluation of fetal wellbeing. There is paucity of information about normal obstetric Doppler indices, particularly from the Indian subcontinent. The aim of the study was to nd the values of pulsatility index (PI), resistive index (RI) of umbilical artery (UA), and fetal middle cerebral artery (MCA) and calculate cerebro-placental ratio (CP ratio) for 31–41 weeks of normal gestation. METHODS : 250 patients were enrolled in the study for color Doppler study of UA and MCA and were serially followed up at 4–6 weeks interval for Doppler indices. Angle-independent Doppler indices like PI and RI for MCA and UA were obtained during each examination. CP ratio was calculated in each case. All the cases were followed up till delivery and the perinatal outcome was recorded. RESULTS & CONCLUSION : Abnormal cerebroplacental ratio is strongly correlated with IUGR and worse fetal prognosis. Fetuses with abnormal doppler velocimetry have a signicantly higher incidence of preterm birth, low birth weight and admission to NICU.Associated risk factors were anemia, PIH, DM, previous history of IUGR, TORCH infection, thyroid disorder. Anemia was found to be common risk factor followed by PIH. In conclusion with the help of non-invasive color Doppler parameters we can identify those pregnancies which are at risk and intervene before the fetus actually become growth restricted and act accordingly for better perinatal outcome.

Objective: Diabetes can lead to diabetic retinopathy, which damages the retina due to blood flow remodeling of occular vessels. Early stages of diabetic retinopathy may not present with patient symptoms. Doppler indices, of the ophthalmic arteries, could help in determining the effect of diabetic vascular remodeling. This research was designed to compare the Doppler indices, in the ophthalmic artery and central retinal artery, in both diabetic and nondiabetic patients. Materials and Methods: This was a cross-sectional observational study of 72 total patients. Sonography was performed on the ophthalmic arteries of 36 diabetics and 36 nondiabetics, to compare Doppler indices. All patients were voluntarily consented to this research that was approved by the university’s Institutional Review Board (IRB). Doppler parameters recorded were peak systolic velocity, end dystopic velocity, resistive index, and pulsatility index, which were taken in both patient groups and compared. Results: A significant difference was noted in the ophthalmic artery peak systolic velocity, end-diastolic velocity, pulsatility index, and resistive index for diabetic and nondiabetic individuals, with a statistically significant set at .01. Conclusions: There was a significant difference between diabetic and nondiabetic ophthalmic Doppler indices in this cohort of patients. This cohort demonstrated vascular remodeling of the ophthalmic arteries, caused by diabetes; therefore, blood flow resistance was increased due to diabetes.

Purpose: Arterial waveform parameters (WPs) are commonly used to monitor and diagnose systemic diseases. Color Doppler Imaging (CDI) is a consolidated technique to measure blood velocity profile in some of the major ocular vessels. This study proposes a computer-aided manipulation process of ophthalmic artery (OA) CDI images to classify and quantify WPs that might be significant in the assessment of glaucoma.Methods: Fifty CDI images acquired by four different operators on nine healthy individuals and 38 CDI images of 38 open-angle glaucoma (OAG) patients were considered. An ad-hoc semi-automated image processing code was implemented to detect the digitalized OA velocity waveform and to extract the WPs. Concordance correlation coefficient (CCC), two-sample t-test and Pearson’s correlation coefficient were used to test for similarities, differences and associations among variables.Results: The OA-CDI images manipulation proposed showed a higher concordance between measured peak systolic velocity (PSV) data and extracted PSV data (0.80≤CCC≤0.98) than on end diastolic velocity (EDV) (0.45≤CCC≤0.63) and resistive index (RI) (0.30≤CCC≤0.58) data. In OAG patients, EDV, RI, subendocardial viability ratio (SEVR), period (T), area ratio (f) and normalized distance between ascending and descending limb (DAD/T) were found statistically correlated to at least one of the following factors: gender, age, ocular medications and year of diagnosis. When compared to healthy individuals, OAG patients OA-CDI profiles showed statistically higher values of f (p < 0.001) and DAD/T (p = 0.002) (p-values corrected by age and gender).Conclusion: The proposed computer-aided manipulation of OA-CDI images allowed to identify DAD/T as a novel WP that vary significantly among healthy individuals and OAG patients, and among female and male OAG patients. Future studies on longitudinal OAG data are suggested to investigate the potential of DAD/T to predict severity and progression of the disease.
