Objective: The objective of this study was to determine the hemodynamic changes in the umbilical artery (UA) and middle cerebral artery (MCA) with oligohydramnios, during third trimester of pregnancy. Materials and Methods: A cross-sectional descriptive study was done in a perinatal ultrasound center, over a 9-month period. The participant sample size was 64, and all of the women were conveniently consented and selected for the study. All individuals were referred for obstetrical sonography in the third trimester, with oligohydramnios. All fetal anomalies, such as a neural tube defect, dwarfism, an abdominal wall defect, were excluded from the study. Results: The mean systolic to diastolic (S/D) ratio for the UA was 3.01, within a range of 1.49 to 5.60 (± 0.79 SD). The mean pulsatility index (PI), of the UA, was 1.11, within a range of 0.41 to 5.51 cm (± 0.64 SD). The mean resistive index (RI) of the UA was 0.66, within a range of 0.33 to 1.25 cm (± 0.13 SD). The mean S/D ratio of the MCA was 5.68, within a range of 2.05 to 26.10 (± 3.10 SD). The mean PI of the MCA was 1.67 within a range of 0.75 to 2.55 cm (± 0.45 SD). The mean resistive index (RI), of the UA, was 0.82 within a range of 0.51 to 1.77 cm (± 0.82 SD). Conclusion: The Doppler indices may rise as pregnancy advances, especially in fetuses with oligohydramnios. In these types of patients, the flow within the MCA may decrease, with an increase in the gestational age. Consequently, it appears that oligohydramnios may lead to vascular remodeling of the UA and MCA.

Renal cysts are a common finding on routine ultrasound scans. Renal cysts are easily detected with ultrasound, with its low cost, non-invasiveness and no exposure to radiation, ultrasound is an exceptional method for primary evaluation of patients with cystic lesions. Most cysts detected by chance and are benign, but they can become complex if infection, bleeding, or ischemia occur. Objective: To assess the prevalence of renal cysts and find relationship with age and sex in the study group and to outline the differential diagnosis of renal cyst by ultrasonography. Methods: This was a cross-sectional descriptive study. An ultrasound examination was performed on 109 patients who were diagnosed with renal cysts. Cystic wall thickness, form, number of cysts, and acoustic enhancement were employed as sonographic criteria for evaluating renal cysts. Results: The incidence of renal cysts were more in females than in male s(52.3% vs. 47.7%). The majority of the cysts were solitary than multiple (69.7% vs. 30.3%). Most of the cysts were at lower pole cortical cysts (22.9%). Simple cyst was the most common type (90.8%), autosomal-dominant polycystic kidney disease (ADPKD) was 6.4%. 59 patients were asymptomatic and 50 patients were symptomatic with flank pain as the most common symptom. Conclusions: Simple cysts are the most frequently found kidney cysts on ultrasound. Aging and hypertension were common risk factors related with renal cysts. End-stage renal failure is caused by ADPKD, which is the most prevalent genetic cause. Diagnosis and early detection of renal cyst is important, routine ultrasound scans for adults is advisable prior to getting any serious complication.

Diabetic and hypertensive patients are at increased risk of vascular complications. Carotid Doppler ultrasonography serves as a non-invasive gold standard technique/tool to access and monitor carotids hemodynamics and morphology. There is a need to predict difference in carotid artery hemodynamics among hypertensive and diabetic patients.Aim: Aim of this study is to find out the hemodynamics of carotid artery in diabetic and hypertensive patients. Method: Cross sectional study conducted at University Ultrasound Clinic Green Town. All patients were investigated with Toshiba Xario XG with 5-7.5MHz linear probe. Study included diabetic and hypertensive individuals, whereas patients with history of carotid endarterectomy, carotid stenting and co-morbidity were excluded. Total 200 participants were recruited, 41 were diabetic and hypertensive, while 159 were normal subjects. Statistical analysis was performed using SPSS version 21. Results: From 200 participants were recruited, out of them 41 patients with 20.5% were positive with diabetes and hypertension and 159 patients with 79.5% were negative with diabetes and hypertension. Right common carotid artery intima media thickness (IMT) mean ± S.D was 0.659±0.114mm with p-value (0.022). Left common carotid end diastolic velocity mean ± S.D was 16.719±6.303cm/s with p-value (0.002). Conclusion: The study highlighted that common carotid artery intima media thickness (IMT) and common carotid artery end diastolic velocity were significantly correlated with hypertension and diabetes. Our findings revealed that common carotid artery IMT and EDV were significant in hypertensive and diabetic patients. Indeed, hypertension and diabetes are mainly associated with vascular complications.
