Introduction Diameter has been a complementary measurement in the evaluation of venous valvular insufficiency of superficial veins of the lower extremity. Small veins with reflux or large veins without reflux may indicate alternative treatments. Awareness of pelvic vein reflux is increasing. The pelvic vein diameter-reflux relationship was investigated. Methods Findings of lower extremity ultrasound (US) and/or clinical conditions—pelvic pain, dyspareunia and dysmenorrhoea—were indications for pelvic/abdominal venous US. Complete US examination included renal, internal iliac and gonadal/ovarian veins. Diameters of the largest right or left pelvic veins were compared with presence of reflux. Intravaginal US was completed in 104 women, age 46 ± 11 (standard deviation) (range 25-76) years old. Pelvic symptoms were reported by 30 (29%) patients. The other patients had pelvic-related recurrent varicose veins or suspected pelvic source of lower extremity venous reflux. Positive and negative predictive values (PPV, NPV) and other statistics at the 90-95% level were calculated relating diameter to pelvic vein reflux. Results Pelvic vein reflux was detected in 54 (52%) women. Pelvic vein diameters were larger in refluxing, 8.4 ± 1.9 (5.1-14.0) mm, than in nonrefluxing veins, 5.2 ± 1.0 (3.4-8.3) mm ( P < .001 by t test). Diameters ≥6.3 mm had 91% (49/54) sensitivity and 92% (49/53) PPV. Diameters ≤6.3 mm had 94% specificity (47/50) and 89% (47/53) NPV. All veins with diameter ≥8.4 mm ( n = 21) had reflux. All veins with diameter ≤5.0 mm ( n = 27) did not have reflux. Conclusions Probabilities of pelvic vein reflux were estimated based on diameters. Diameter-reflux agreement solidifies diagnosis. An explanation for contradiction between small diameter and reflux or large diameter and no reflux is recommended.

Objective Pelvic venous reflux may be responsible for pelvic venous disorders and/or lower-limb (LL) varicose veins. Ultrasound investigation with Doppler allows a complete study of the entire infra-diaphragmatic venous reservoir. The aim of this study was to guide and standardize the investigation of the pelvic origin of venous reflux in female patients with LL varicose veins. Methods In this case-control study, we applied a comprehensive ultrasound investigation protocol, which involved four steps: (1) venous mapping of the lower limbs; (2) transperineal and vulvar approach; (3) transabdominal approach; and (4) transvaginal approach. Results Forty-four patients in group 1 (patients with LL varicose veins and pelvic escape points [PEPs]) and 35 patients in group 2 (patients with LL varicose veins without PEPs [control group]) were studied, matched by age. The median age was 43 years in both groups. The calculated body mass index was lower in group 1 (23.4 kg/m²) compared with the control group (25.4 kg/m²), and this difference reached statistical significance (P < .001). The presence of pelvic varicose veins (PVs) by transvaginal ultrasound was 86% in group 1 and 31% in group 2. Perineal PEPs were the most prevalent, being found in 35 patients (79.5%), more frequent on the right (57.14%) than on the left (42.85%) and associated with bilateral PVs 65.7% of the time. In group 1, 23 patients (52%) reported recurrent varicose veins vs eight patients (23%) in the control group (P = .008). Regarding the complaint of dyspareunia, a significant difference was identified between the groups (P = .019), being reported in 10 (23%) patients in group 1 vs one patient (2.9%) in the control group. The median diameters in the transabdominal approach of the left gonadal veins were 6.70 mm for group 1 and 4.60 mm for group 2 (P < .001). In patients with PVs in group 1, the median diameter of PEPs at the trans-perineal window was 4.05 mm. In the transvaginal examination, the mean diameter of the veins in the peri uterine region was 8.71 mm on the left and 7.04 mm on the right. Conclusions The identification of PEPs by venous mapping demonstrates the pelvic origin of the reflux and its connections with the LL varicose veins. For a more adequate treatment plan, we suggest a complete investigation protocol based on the transabdominal and transvaginal study to rule out venous obstructions, thrombotic or not, and confirm the presence of varicose veins in the pelvic adnexal region.

The most frequent site of carotid artery involvement in patients with TIPIC is the carotid bifurcation, more precisely the bulbar region. 8 Corticosteroid therapy remains the first-line treatment for sarcoidosis, except when contraindicated. 9 If the disease is not controlled in the induction phase (generally within 3 to 6 months), the use of immunosuppressants as second-line treatment can be considered. ...

... No Brasil, de acordo com dados do Ministério da Saúde entre 2010 e 2021, houve mais de 520 mil internações devido a trombose venosa profunda, com um total de mais de 67.000 óbitos registrados entre 2010 e 2019. Nessa conjuntura, a detecção precoce e o diagnóstico adequado são fundamentais para o tratamento, ajudando a reduzir os eventos adversos associados e a excluir diagnósticos alternativos (Albricker et al., 2022). Nesse aspecto, nota-se que a embolia pulmonar constituem graves problemas de saúde pública nacional e internacional, devido aos altos custos associados a episódios agudos de tromboembolismo venoso (TEV) e a complicações a longo prazo. ...

... 4,13,14 Doppler US is the most appropriate exam because of its cost-benefit profile, availability, and low invasivity, because it is radiation free, and because it has a good capacity for morphological and hemodynamic assessment of plaques and the degree of stenosis. 15,16 Moreover, it has 99% sensitivity and 88% specificity for plaques exceeding 60%. 17 Despite the method's advantages, Doppler US screening is not recommended in asymptomatic patients in the adult population in general who have no significant risk factors 16 (evidence level B and recommendation grade 1) 10 (evidence level D). ...

... Foi identificada uma incidência de 23,7% para sinais de inflamação ou obstrução venosa no exame físico(1,25).É recomendado que para a manutenção dos cateteres venosos realizar o flushing e aspiração para verificar o retorno de sangue antes de cada infusão para garantir de forma segura o funcionamento do cateter(1,38). Diante disso, foram citados nos estudos a utilização da solução salina para avaliação da manutenção do cateter para esse fim, contudo vem sendo trazida a associação com a POCUS para o procedimento de flushing(24,26,28,31,40).É identificado em estudos, que pacientes hospitalizados com fragilidades da rede intravenosa, a utilização do Ultrassom contribui para o tempo de sobrevida do cateter(5,8). Dentre os fatores associados à fragilidade da rede venosa evidenciam-se a obesidade, diabetes, múltiplas punções, câncer e pacientes em longo período de internação(39).Quando visualizada no eixo curto, a imagem anecóica do vaso há um ponto hiperecóico centralizado indicando a ponta do cateter. ...

This Guideline was developed by cardiologists from the Department of Cardiovascular Imaging (DIC) at the Brazilian Society of Cardiology (SBC), angiologists and vascular surgeons from the Brazilian Society of Angiology and Vascular Surgery (SBACV), and radiologists from the Brazilian College of Radiologists (CBR) -who are experts in vascular ultrasound (VUS) -with the aim of supporting the best use of VUS based on the current medical literature, as well as of updating the 2015 Guideline. 1 The rationale for the use of VUS in the diagnosis of important diseases was based on the recommendations of the 2015, 2016, and 2019 DIC expert panel. 1,15,16 Other topics included in this update are: transcranial Doppler, US enhancing agents (USEAs), and diagnostic aspects of carotid stenosis by computed tomography angiography (CTA) and magnetic resonance angiography (MRA). However, interested readers should seek more comprehensive and specific publications for further information on these other imaging modalities. ...
