Background: Cerebral ischemic stroke is the major cause of death after ischemic heart disease and malignancies, among which major cases of stroke results from atherosclerosis of intra and extra-cranial carotid vessels. The aim of this study is to evaluate the extracranial carotid arteries in patients with ischemic stroke and correlation with various risk factors. Materials and Methods: A cross sectional study of the patients with ischemic stroke presented in Radiology department of Nobel Medical College were evaluated for a period of one year from February 2017- January 2018 using color Doppler ultrasound and correlated with various risk factors. A total of 50 patients were included in the study. All age groups and sex were included. Results: Out of 50 patients, 29 patients (58%) were males and 21 patients (42%) were females. Stroke was present in 24 patients on right side and 26 patients on left side. A total of 36 patients had extra-cranial carotid stenosis. Among them, 18 patients had <50% stenosis, 17 patients had >50% stenosis and 1 patient had complete occlusion. The most common cause of obstruction was found to be atherosclerotic changes in the form of atheromatous plaque. Out of 50 patients 27 had history of hypertension and 19 had history of smoking. Out of 27 hypertensive patients, 23 had stenosis which is statistically significant (p value 0.024).    Conclusion: The current study shows the importance of color Doppler ultrasound as an economic, safe and non-invasive method of demonstrating the cause of stroke in extra-cranial carotid artery system

Vascular torsion is a rare renal transplant complication which requires prompt diagnosis and surgery to salvage allograft function. We report here a case of renal allograft torsion with interesting imaging findings on unenhanced CT and color Doppler ultrasound. A 60-year-old woman with a history of pancreas and kidney transplant presented to the emergency room with nausea, vomiting, abdominal pain, and minimal urine output. Unenhanced CT of the abdomen demonstrated an enlarged and malrotated renal allograft with moderate hydronephrosis. Color Doppler ultrasound demonstrated lack of vascularity within the allograft. The patient was taken urgently to the operating room where the renal allograft was found twisted 360 degrees around the vascular pedicle. After the allograft was detorsed, the color of the kidney returned and the Doppler signals for arterial flow improved. Intraoperative biopsy showed no evidence of infarct or acute cellular rejection. The detorsed kidney was surgically fixed in position in its upper and lower poles. Follow-up ultrasound 1 day later demonstrated normal blood flow to the renal allograft and the serum level of creatinine returned to normal.

Abstract Background: Nowadays, the number of elderly has steadily increased annually. Elderly patients with ischemic stroke often have worse outcomes than younger patients. However, there has not been a study of ischemic stroke in the elderly in Thailand. A better knowledge of the risk factors, subtypes, and outcomes of strokes in the elderly may have significant practical implications for the aged society in the future. The objective of the study was to assess the risk factor, stroke subtypes, and outcome of stroke in the elderly compared to the younger patients.Method: All patients presented with acute ischemic stroke and transient ischemic attack (TIA) aged over 45 years who were admitted in the Stroke unit between November 1st, 2016 and December 31st, 2017 were retrospectively studied.Result: 542 patients were included. The average age was 68.78±12.03, 44.8% of them were male. 186 (34.3%) patients were 75 or older. Cardioembolism was found to be the most common cause of ischemic stroke in 156 patients (28.8%). Patients who were 75 or older had significantly worse outcomes in all categories including NIHSS at discharge, modified Rankin scale, length of stay and the number of deaths) compared to the younger group. Atrial fibrillation was the risk factors associated with older age with OR 3.861 (p value<0.001). Aged 75 years or older, atrial fibrillation, more NIHSS score on admission and history of the previous stroke were the risk factors associated with a patient's death.Conclusion: The elderly who are 75 years or older accounts for more than one-third of ischemic stroke in our study. Stroke in the elderly correlates with higher mortality and poorer outcome. Cardioembolism related to atrial fibrillation is the major cause of stroke in this population.

Objective: To observe the early changes of uterine incision defects after cesarean section by transvaginal color Doppler ultrasound, and to analyze the risk factors of their formation. Methods: A total of 181 women who underwent cesarean section from September 2016 to June 2018 and who underwent transvaginal ultrasound examination at 6 weeks, 3 months, and 6 months after birth were divided into two groups. (142 cases) and incision defect group (39 cases). The incision changes and the risk factors of incision defect in different periods of postpartum were analyzed. Results: Compared with the group with good incision healing, the length of the incision defect in the cesarean section at 6 months after delivery was shorter than that at 6 weeks after delivery (P < 0.05). The results of non-conditional logistic regression showed that the number of cesarean sections increased and the number of operators was lower. Seniority, postoperative infection, posterior uterine position, and incision close to the cervix are risk factors for poor healing of uterine scars. Conclusion: As the postpartum time increases, the length of the cesarean section incision defect shortens; multiple cesarean sections, puerperal infections, posterior uterus, low incision position and inexperience of the operator are the risk factors for the formation of uterine incision defects and increase uterine scars. Risk of poor healing.

Ovarian Masses

Background: Ovarian cysts known as ovarian masses, are commonly found incidentally in asymptomatic women. Ovarian cancer is the 7th most frequent cancer in women worldwide, as well as the eighth leading cause of cancer death. Ultrasonography is the principal imaging technique for confirming the mass ovarian origin and determining whether the mass is benign or malignant. Method: This descriptive cross sectional study was conducted from 15 June to December 2019 in the Radiology Department of Avicenna Medical College. A total of 90 ultrasounds undertaken at the Gynecological Ultrasound Unit. A total of 32 patients with functioning ovarian cysts were included. A total of 46 individuals with benign tumors and 9 patients with malignant cysts were included in the control group. The remaining patients were not followed up on and were treated at a different center. The majority of the patients had issues with their menstrual cycle and pain. Results: The mean age of the patients was 35.6+9.16. In functioning ovarian cysts, benign tumors & ovarian tumors. The functioning ovarian cysts had a mean size of 40.8 mm +16.35 mm. Differences were significant found between1this group & other1two groups: A mean size of 61.75 +65.5; P, 0.001 was seen for non-functional benign ovarian disease; and the average size of malignant cysts was 85.9 +50.6; P = 0.001. Out of 32 functional1ovarian cysts, 22 were found by ultrasonography, 8.0 were not identified and 2.0 cases were1diagnosed ultra-sonographically as functional ovarian cysts but histologically revealed to be benign ovarian cysts (non-functional). The sensitivity of color Doppler ultrasound was determined to be 82.0%. Conclusion: The study's findings revealed that ultrasound had an 82 percent sensitivity in diagnosing ovarian masses, increasing its accuracy. As a result, ultrasonography appears to be the first modality of choice in the examination of any woman suspected of having an ovarian tumor. Also, to rule out the need for unnecessarily surgical procedures in benign lesions. Keywords: Ovarian Cysts, cancer, ultrasound

Retronychia, the posterior embedding of the nail bed into the proximal nail fold, can be a complex clinical dermatologic diagnosis that may mimic other inflammatory ungual diseases or tumors of the nail. It has been related to a history of severe systemic conditions that secondarily affect the nail matrix and is commonly associated with onychomadesis. We present a case of retronychia of the foot with a purely traumatic origin, nonconcomitant with onychomadesis, that was diagnosed by color Doppler ultrasound in a long-time practitioner of martial arts who was otherwise healthy. Color Doppler ultrasound is an excellent imaging technique for supporting the diagnosis of retronychia. It provides information on the exact location and morphology of the nail plate as well as the presence of inflammatory signs in the ungual and proximal periungual regions. Additionally, this imaging technique can support the differential diagnosis with other nail conditions. Since there are many sports or activities that can potentially injure the toenails, retronychia may be an underestimated entity and the present case can raise the awareness of this condition and show the usefulness of color Doppler ultrasound.
