“…Unilateral presentation of DVT was encountered more in 87.2% (34/39) comparing favorably with a retrospective study by Lemech et al(2004) that found 69%(n=1029) 12 but differed in the bilateral presentation of the symptoms in 31%(n=1029) unlike in our study where we found only 12.8%(5/39). This could be as a result of the higher number recruited in their study 1029 verses 103 participants and their study only looked at cases with DVT specifically.…”

Background: Imaging modalities in lower limb swelling play a major role in identifying various pathologies that have significant impact in clinical outcomes. Ultrasonography has been shown to have comparable outcome with advanced techniques like Magnetic Resonance Imaging (MRI) in soft tissue imaging and it is real time and fairly non-invasive. Objectives: To evaluate clinical findings and describe patterns of sonographic findings in lower limb swelling at Moi Teaching and Referral Hospital (MTRH) Eldoret, Kenya. Methods: This was a cross sectional study done in the MTRH, Radiology and Imaging Department. Using purposive sampling, 109 patients were recruited. 4 declined consent while 2 withdrew. Data was analyzed using STATA version 10. Descriptive statistics were used for continuous variables while frequency listings were used for categorical variables. Chi square test was used to assess associations between categorical variables. Results: Their median age was 41 years and the majority were women 67(65%). The main complaint was unilateral lower limb swelling 80 (77.7%), and pain in 54(52.4%). Trauma and immobility were in 18(17.5%) and 19(18.4%) respectively. The main clinical examination finding was localized swelling in 63(61.2%), the commonest location being in the lower leg 52(50.5%). Redness was in 31(30.1%) while tenderness was demonstrated in 41(39.8%) cases. The most frequent sonographic finding was deep venous thrombosis (DVT) 39(37.9%). Lymphadenopathy and oedema were 9(8.7%) each while varicose veins and cellulitis were 7(6.8%) and 6(5.8%) respectively. Conclusion: The most frequent finding in lower limb swelling was deep venous thrombosis (DVT).

“…[1][2][3] Conversely, other authors have advocated the importance of bilateral studies, especially in patients with predisposing risk factors for thrombosis. 4,5 Prior to the development of venous duplex imaging, patients underwent venography, which was typically done as a unilateral study because of its invasive nature. Is it possible to identify which patients should undergo bilateral examinations?…”

Inpatients have a very high incidence of clinically silent contralateral thrombosis (34%) and should usually undergo bilateral examinations. Patients with active malignancy have a 38% incidence of asymptomatic contralateral clot and should always have a bilateral study. Outpatients with unilateral symptoms and no associated risk factors for thrombosis can safely undergo unilateral examinations and should be adequately treated according to the unilateral findings. Algorithms to select patients for limited studies should include screening data for active malignancy, recent trauma or surgery, pregnancy, hormone therapy, or history of thrombophilia.

“…However, inpatients with unilateral symptoms were diagnosed with thrombosis on the symptomatic side in 24% of cases, on the asymptomatic limb in only 5%, and on both limbs in 5% of cases 21 . In another study, Lemech et al found about 10% of bilateral DVT in patients with unilateral symptoms, thus suggesting that inpatients should have both limbs investigated 22 .…”

A trombose venosa profunda é uma entidade clínica potencialmente grave, responsável por elevada morbimortalidade. A ecografia vascular representa o método propedêutico de escolha no diagnóstico e acompanhamento dos pacientes com essa doença. Entretanto, várias questões permanecem controversas, tais como a abordagem inicial do paciente com suspeita de trombose venosa profunda, os tipos de protocolo a serem usados, o tempo para a realização do exame e a trombose no plexo de panturrilha. O objetivo dessa revisão é discutir esses assuntos à luz dos conhecimentos atuais.
