“…Two hundred (200) patients were recruited, with a preponderance of males in our study (M:F=106:94). This was in sharp contrast to findings of a similar research by Salaam AJ et al [9] in which more females were scanned (M:F=59:67).The male predominance in our study is however in agreement with earlier studies by Olatunji AA [6] and Ikpeme A [31] which reported a male to female ratio of 29:13 and 51:25 respectively. This may just be coincidental, but most likely attributed to the increased incidence of vascular lesions in the males as reported by Michael H et al [34].…”

“…There was no precise consistent percentage agreement with previous studies. However, DVT featured prominently as an important diagnostic Doppler finding in 13(31%), 9(12%) and 21(18.3%) patients scanned by Olatunji AA et al [6], Ikpeme A et al [31] and Salaam AJ et al [9] respectively. The lower values in their studies could be explained in part by the comparatively smaller sample size of 42,76 and 126 patients recruited respectively, compared to ours with 200 patients.…”

Background: Doppler ultrasound scan (DUS) is a valuable, cost effective, and relatively rapid diagnostic technique that provides a non-invasive assessment of the vascular circulation in the lower limb. Aims: To determine the pattern of lower limbs Doppler requests in our environment and to evaluate the Doppler findings. Study Design: Retrospective study Place and Duration of Study: Radiology department of Benue state university Teaching Hospital over a one-year period from January 2018 to December 2018. Methods: We included 200 patients that had lower limb Doppler ultrasound for various indications. Data on age, gender, indications and findings was retrieved from departmental cards and case notes, then collated and analyzed using SPSS software version 23, with the P value taken as =.005. Results: Two hundred patients were scanned;106 males and 94 females with age range of 10-109 years. Their mean age was 34.2 ±13.5 years. Most patients 48(24.0%), who presented for Doppler sonography of the lower limb had diabetic foot ulcer (DFU), followed by left leg swelling in 42(21.0%) patients. DVT alone was indicated in 33(16.5%) patients. Both DFU and DVT were more in the male patients with a M:F ratio of 26:22 and 21:12 respectively. The indications for lower limb doppler ultrasound scan are seen to generally increase with increasing age, with the least among those less than 40years 32(16.0%) and highest among the greater than 60years age groups 89(44.5%). At doppler ultrasound, there are more patients with Deep vein thrombosis (DVT) 104(52.0%). Normal study and peripheral vascular disease (PVD) have equal incidence respectively in 48(24%) of the patients. DVT and PVD were more in the male group with a M: F ratio of 55:49 and 27:21 respectively while normal studies were seen equally in both sexes (M: F=24:24). Conclusion: Doppler ultrasound has been shown to be a cost-effective and valuable non-invasive tool for the diagnosis of lower limb vascular diseases.

“…Venous thrombosis is a well-known disease that accompanies various pathological states. It frequently coexists with injuries of the pelvis, upper, and lower limbs [ 1 ]. It may also occur during immobilization, hospitalization, after accidents or procedures, such as venous catheterization, injections, or intravascular procedures [ 2 ].…”

SummaryBackgroundVenous thrombosis is a multicausal disease involving intravenous clot formation. It may occur spontaneously or after provoking events, such as traumatic injuries to the pelvis, upper and lower extermities, immobilization, intravascular procedures, including venous catheterization or injection. Color Doppler ultrasonography is a rapid and non-invasive technique for evaluation of venous disease. It is a very sensitive method for detection of thrombi, but has some limitations, e.g. inability to distinguish between an old and fresh thrombus. Elastography as a method for evaluation of tissue elasticity and allows more accurate assessment of venous thombosis. The thrombus solidifies significantly during the process of remodeling, thereby changing elasticity, while the tissues located around the vessel remain unchanged. Moreover, the homogeneity of the thrombus is also changed. These factors allow for exact determination of the age of the thrombus depending on changes of its elasticity.Material/MethodsThe object of this study was to assess thrombus age in patients with saphenous vein insufficiency treated with sclerotherapy. We examined 34 patients, 30 women and 4 men, aged 18–62 years. All short-listed patients with initial 7–8 mm vessel diameter underwent treatment with 3% Aetoxysklerol mixed with CO2 and other respiratory gases. Data acquisition was performed using an Esaote MyLab Twice device with LA523 linear probe.ResultsOn the sixth day after the treatment 31 patients presented uniform, hypoechogenic thrombus in B-mode image. Ultrasound-based elasticity images (elastography) showed significant predominant red and green areas. Blue area was either invisible or appeared in insignificant grade on examined area. The mosaic image of colors appeared on 2 patients. On the fourteenth day of study 21 patients still presented hypoechogenic thrombus, whereas mixed echogenicity of thrombus appeared on 11 patients.On 28 examined patients mosaics of red, green and blue colors were observed, with blue color significantly predominating over red color. 3 patients presented mosaics of colors without a predominate color.ConclusionsElastography as a method of thrombus evaluation, provides information about relative shrinkage of blood clot. It seems that elasatography can improve accurate assessment of the exact age of thrombus.

Background: Ultrasound is a portable technology able to deploy health care effectively in low resource settings. This study presents a systematic review to determine trends in the utility and applicability of this technology in low-and middle-income countries (LMIC), specifically for surgical applications. The review includes characterising and evaluating trends in the geographic and specialty-specific use of ultrasound pertaining to surgical disease. Methods: The databases such as Medline OVID, EMBASE and Cochrane were searched from 2010 through March 2019 for studies available in English, French and Spanish. Commentaries, opinion articles, reviews and book chapters were excluded. A categorical analysis of ultrasound use for surgical disease in LMICs was conducted. Results: A total of 6276 articles were identified, with 4563 studies included for the final review. A total of 221 studies were selected researching ultrasound use in LMICs to treat surgical disease. Most studies identified ultrasound usage focused on general surgery, acute care surgery and surgical ICU topics (52%, 115) followed by computed tomography surgery studies (20%, 44). Most studies were retrospective in nature, with 81% (180) of research studies generated in four countries (India, Pakistan, Nigeria and Egypt). Ultrasound proved to be a feasible technique for utility in pre-operative diagnosis, cost-effectiveness and prediction of surgical outcomes. Findings are limited by the limited number of randomised clinical trials reported. Conclusion and global health implications: Our systematic literature review of ultrasound use in LMICs demonstrates the growing utilisation of this relatively low-cost, portable imaging technology in low resource settings for surgical disease.
