Diagnosing deep vein thrombosis and pulmonary embolism has become definitely easier and more reliable over the past fifteen years, especially thanks the development of lower limbs venous compression ultrasonography and fibrin D-Dimer measurement. These tests allowed reducing the requirement for venography and pulmonary angiography to a small minority of patients. Simultaneously, ventilation/perfusion lung scan criteria have been standardized, and the performance of spiral computed tomography has been analyzed in an appropriate way. New sequential, mainly noninvasive strategies could be developed that proved to be safe in large-scale prospective cohort studies with prolonged follow-up. They should now be implemented in daily practice according to cost-effectiveness analyses as well as local facilities and expertise.

Modern non-invasive diagnostic strategies for pulmonary embolism rely on the sequential use of clinical probability assessment, D-dimer measurement, and thoracic imaging tests. Planar ventilation/perfusion scintigraphy was the cornerstone test for the diagnosis of pulmonary embolism for more than two decades and has now been replaced by computed tomographic pulmonary angiography (CTPA). Diagnostic strategies using CTPA are very safe to rule out pulmonary embolism and have been well validated in large prospective management outcome studies. Venous compression ultrasonography is the cornerstone test to diagnose deep vein thrombosis but is not mandatory for the diagnosis of pulmonary embolism when using multidetector CTPA.

High Pretest Probability

Abstract Guidelines for the diagnostic workup of deep vein thrombosis (DVT) recommend assessing the clinical pretest probability before proceeding to D-dimer testing and/or compression ultrasonography (CUS) if the patient has high pretest probability or positive D-dimer. Referring only patients with positive D-dimer for whole-leg CUS irrespective of pretest probability may simplify the workup of DVT. In this prospective management outcome study, we assessed the safety of such a strategy. We included consecutive outpatients referred to the Emergency Department at Østfold Hospital, Norway, with suspected DVT between February 2015 and November 2018. STA-Liatest D-Di Plus D-dimer was analyzed for all patients, and only patients with levels ≥0.5 µg/mL were referred for CUS. All patients with negative D-dimer or negative CUS were followed for 3 months to assess the venous thromboembolic rate. One thousand three hundred ninety-seven patients were included. Median age was 64 years (interquartile range, 52-73 years), and 770 patients (55%) were female. D-dimer was negative in 415 patients (29.7%) and positive in 982 patients (70.3%). DVT was diagnosed in 277 patients (19.8%). Six patients in whom DVT was ruled out at baseline were diagnosed with DVT within 3 months of follow-up for a thromboembolic rate of 0.5% (95% confidence interval, 0.2-1.2). A simple diagnostic approach with initial stand-alone D-dimer followed by a single whole-leg CUS in patients with positive D-dimer safely ruled out DVT. We consider this strategy to be a valuable alternative to the conventional workup of DVT in outpatients. This trial was registered at www.clinicaltrials.gov as #NCT02486445.

Abstract Abstract 3999 Poster Board III-935 Background Clinical advantage of extensive screening for occult cancer in patients with idiopathic Deep Vein Thrombosis (DVT) is unknown. We have demonstrated that the Residual Vein Thrombosis (RVT)-based screening for occult cancer improves early detection as well as cancer-related mortality (Siragusa S et al. Blood 2007;110(699):OC). Here we report on final analysis of 537 patients over a period of 8 years. Objective of the study We conducted a prospective study evaluating whether a RVT-based screening for cancer is sensitive and influences cancer-related mortality. Study design Prospective with two cohorts of DVT patients: the first cohort was monitored for clinical overt cancer only (Group A), while the second (Group B) received complete screening for occult neoplasm and subsequent surveillance. Materials and methods Consecutive patients with a first episode of DVT who presented RVT after 3 month of anticoagulation and without signs and/or symptoms for overt cancer. Screening for occult cancer was based on: ultrasound and/or CT scan of the abdomen and pelvis, gastroscopy, colonoscopy or sigmoidoscopy, hemoccult, sputum cytology and tumor markers. These tests were extended with mammography and Pap smear for women and ultrasound of the prostate and total specific prostatic antigen (PSA) for men. All investigations had to be completed within four-weeks from the assessment of RVT. All patients were followed-up for at least 2 years. Incidence and cancer-related mortality was compared between the two groups by survival curves (Kaplan-Mayer) and related Breslow test for statistics. Results Over a period of 8 years, 537 patients were included in the analysis: first cohort included 346 patients (Group A), second cohort 191 (Group B). Clinical characteristics between groups were homogenous. During the follow-up, 8.3% of patients developed overt cancer in group A; in group B, 7.8% of patients had diagnosed cancer at the moment of extensive screening while 2 new cases (0.7%) occurred during the follow-up (Table). The sensitivity of this approach was 92.1% (95% confidence intervals 75.2-104.2). Cancer-related mortality was 7.5% in group A and 3.6% in group B (p< 0.001). Conclusions The RVT-based screening for occult cancer is highly effective for improving early detection as well as cancer-related mortality in a cohort of 537 patient with DVT of the lower limbs.

Objectives: The treatment of deep vein thrombosis (DVT) of the lower limbs during pregnancy remains controversial. There are a lot of problems related to anticoagulant therapy for the safety of the fetus; the use of caval filters rarely appears in the literature and it is not yet codified. So the choice of the right treatment is often difficult. The authors review their experience with a prophylactic use of a temporary caval filter for patients with proximal DVT of the last period of pregnancy, in order to avoid the inherent risk of major pulmonary embolism during delivery and postpartum. Methods: Ten women with proximal DVT were treated. The diagnosis was performed by Doppler ultrasonography (DU) and magnetic resonance (MR). At the end of pregnancy, a temporary caval filter (eight Prolyser and two Tempofilter) was percutaneously inserted under X-ray control. The patients were then subjected to a planned caesarean section. After 15 days, all filters were removed after a phlebography to check the absence of clots. Results: The mean time of X-ray exposure was about 1 min and 30 s. None of the patients suffered a major pulmonary embolism. All fetuses were born without problems or malformations. There were no complications related to the filters. No caval thrombosis or filters clots were found at the phlebography. The follow-up registered no pulmonary embolism episodes. Conclusions: The use of a temporary caval filter in pregnancy is safe and does not introduce any additional risk. It could be suggested for pregnant patients with proximal DVT beginning in the last period of pregnancy.

Abstract Abstract 2306 Background: One in every three patients with deep vein thrombosis (DVT) may have silent pulmonary embolism (PE), but its clinical relevance has not been thoroughly studied. Methods: We used the RIETE Registry data to compare the clinical characteristics, diagnostic tests, and 3-month outcome in 842 patients with proximal DVT in the lower limbs and silent PE at baseline, 1533 with DVT without PE, and 585 patients with DVT and symptomatic PE. Results: On admission, a minority of DVT patients (with or without silent PE) presented with hypoxemia (9.0% vs. 6.4%, respectively), or typical PE signs on the chest X-ray (25% vs. 22%) or electrocardiogram (23% vs. 17%). Patients with symptomatic PE more frequently presented with hypoxemia (30%) or had PE signs on the chest X-ray (41%) or electrocardiogram (37%). After the initial 15 days of follow up the incidence of PE was higher among patients with DVT and silent PE compared to those with symptomatic PE (0.95% vs. 0.17%).During the first 90 days of anticoagulant therapy, patients with DVT without PE had a lower incidence of recurrent PE than bleeding (1.0% and 2.9%, respectively). Of note, an excessive risk for bleeding was observed during the first 2 weeks of therapy among patients without PE. Incidence of recurrent PE and major bleeding was similar in DVT patients with silent PE (1.8% and 1.9%) and in those with symptomatic PE (2.6% and 2.7%). Conclusions: Most DVT patients with silent PE have no hypoxemia, chest X-ray signs or electrocardiographic evidence suggestive of embolism. Frequency of recurrent PE was higher among patients with silent PE at the initial 15 days of follow up. In contrast to other subgroups, in DVT patients without PE at baseline, the incidence of major bleeding far exceeded that of PE development during follow up. Disclosures: No relevant conflicts of interest to declare.

SummaryWe assessed the accuracy of venous compression ultrasonography (CUS) for the detection of asymptomatic deep vein thrombosis in 122 consecutive patients, with a mean age of 69 years, who were hospitalised in an internal medicine unit. All included patients had CUS within 48 h of admission. Twelve out of 17 patients with a positive CUS underwent phlebography, as the others withdrew their consent, whereas the remaining 105 patients with a negative serial CUS testing were clinically followed-up at 3 months. We found that CUS had a sensitivity and a specificity of respectively 1 (95% CI, 0.73 to 1) and 1 (95% CI, 0.96 to 1) for the detection of asymptomatic deep vein thrombosis. Kappa-coefficients for intra-observer and inter-observer agreements were respectively 0.88 and 0.56. We concluded that venous compression ultrasonography, performed as described, fulfils requirements of a screening test that could be available for prophylactic clinical trials or epidemiological researches.

Objective: To determine whether the injection of sclerosant in microfoam form offers a clear alternative to surgery in large varices of the lower extremities. Design: Retrospective observational follow-up study (3–6 years). Patients: Five hundred lower limbs in which pretreatment duplex ultrasound demonstrated insufficiency of sapheno-femoral junctions (diameters 9–32 mm) and long saphenous veins. Main outcome measure: Obliteration and subsequent disappearance of treated veins. Results: After ≥ 3 years follow-up, 81% of treated varicose long saphenous veins were obliterated and 96.5% of superficial branches disappeared. The obliteration of saphenous veins required one injection in 86%, two in 10.5% and three in 3.5% of cases. There were no serious complications such as deep vein thrombosis Pulmonary embolism. Conclusion: The quality and stability of outcomes and ease of repeat treatments when required may make sclerotherapy with microfoam a therapeutic approach of choice for the functional and anatomical elimination of extensive pathological venous areas.

SummaryThe natural history of calf deep-vein thrombosis (DVT) is still uncertain and it is debated whether it warrants to be diagnosed and treated. We aimed to investigate the complication rate of untreated isolated calf DVT (ICDVT). Symptomatic outpatients were prospectively managed with serial compression ultrasonography (SCUS). Those without proximal DVT and with likely pre-test clinical probability (PCP) or altered D-dimer received immediate subsequent complete examination of calf deep veins (CCUS) by a different operator. The result of CCUS was kept blind both to the managing doctor and the patient and disclosed after three months. Primary outcome was the rate of venous thromboembolism at three months. We examined 431 subjects (196 males; median age 68.0 years) in whom five outcomes were recorded (1.2%; 95% confidence intervals [CI]: 0.4–2.7). If CCUS results had been available, outcomes would have been recorded in 3/424 patients (0.7%; 95% CI: 0.2–2.1) with two events in subjects negative at both serial and complete CUS. ICDVT was diagnosed in 65 subjects (15.3%; 95% CI: 12–19); of whom 59 remained uneventful (one was lost to follow-up). A significant higher rate of outcomes was recorded in subjects with than without ICDVT (5/64; 7.8%; 95% CI: 3–17 vs. 3/351; 0.8%; 95% CI: 0–2; p=0.003). However, after excluding two events picked at serial CUS in subjects with ICDVT, the difference became barely significant (3/64; 4.7%; 95% CI: 1–13; p=0.049). Thrombotic evolution of untreated ICDVT in high-risk subjects may be relevant. Larger studies are needed to address this issue.

Objectives: To present a single-centre experience on CT pulmonary angiography (CTPA) for the assessment of hospitalised COVID-19 patients with moderate-to-high risk of pulmonary thromboembolism (PTE). Methods: We analysed consecutive COVID-19 patients (RT-PCR confirmed) undergoing CTPA in March 2020 for PTE clinical suspicion. Clinical data were retrieved. Two experienced radiologists reviewed CTPAs to assess pulmonary parenchyma and vascular findings. Results: Among 34 patients who underwent CTPA, 26 had PTE (76%, 20 males, median age 61 years, interquartile range 54–70), 20/26 (77%) with comorbidities (mainly hypertension, 44%), and 8 (31%) subsequently dying. Eight PTE patients were under thromboprophylaxis with low-molecular-weight heparin, four PTE patients had lower-limbs deep vein thrombosis at ultrasound examination (performed in 33/34 patients). Bilateral PTE characterised 19/26 cases, with main branches involved in 10/26 cases. Twelve patients had a parenchymal involvement >75%, the predominant pneumonia pattern being consolidation in 10/26 patients, ground glass opacities in 9/26, crazy paving in 5/26, and both ground glass opacities and consolidation in 2/26. Conclusion: COVID-19 patients are prone to PTE. Advances in knowledge: PTE, potentially attributable to an underlying thrombophilic status, may be more frequent than expected in COVID-19 patients. Extension of prophylaxis and adaptation of diagnostic criteria should be considered.
