“…There are limited data investigating whether the initial thrombus size has an effect on the overall resolution. Sartori et al [14] found that the recanalization rate was not correlated to calf vein thrombus diameter at enrolment (p = 0.93), and there was no difference in recanalization rates between clots that were <5 mm and ≥5 mm.…”

The Natural History of Uterine Venous Plexus Thrombosis

The management of incidental or unusual site venous thrombosis (VT) is challenging and is often extrapolated from studies on symptomatic deep venous thrombosis (DVT). There is a tendency to treat with anticoagulation, due to the theoretical risk of propagation and embolism; however, this is not without risk. Furthermore, there is little guidance on how to monitor incidental VT. The aim of this study was to describe the natural history of incidental uterine venous plexus thrombosis (UVPT) and provide a structured approach to its overall management. A prospective study was conducted in a university teaching hospital over a 16-month period. Women diagnosed with UVPT on transvaginal ultrasound (TVS) were followed up over a six-month period and managed based on an individualised risk assessments, in conjunction with haematologists. Fifty women were diagnosed with UVPT during the study period, of which 38 were managed expectantly. The resolution was documented in 70% of women. There were no cases of symptomatic DVT or pulmonary embolisms in either the expectant or treatment groups. Our study has shown that in a high proportion of women, incidental UVPT could be managed successfully without the need for anticoagulation. The overall management of UVPT should be based on individualised clinical risk assessments.

Objective: We evaluate the efficacy of anticoagulant administration for isolated distal deep vein thrombus (IDDVT), detected before orthopedic surgery.Materials and Methods: The study included 32 patients diagnosed with IDDVT before orthopedic surgery in our hospital between October 2011 and October 2017. They were divided into two groups: the ‘pre- and post-operative therapy group,’ who were administered anticoagulants both pre- and post-operatively, and the ‘post-operative therapy group,’ who were administered anticoagulants only after surgery due to risk of bleeding judged by an orthopedic surgeon. We compared the primary efficacy (change in IDDVT size) between the two groups.Results: The proportion of patients with increased post-operative IDDVT sizes was significantly larger in the post-operatively treated group than in the pre- and post-operatively treated group (44.4% vs. 8.7%, p=0.026). No case demonstrated an IDDVT extension proximal to the popliteal vein or presented with symptomatic pulmonary thromboembolism in this study.Conclusion: Based on our findings, we recommend that, in patients with IDDVT detected prior to orthopedic surgery and administered anticoagulant therapy only after the procedure because of a bleeding risk, a lower limb ultrasonography to re-evaluate the existing deep vein thrombus should be conducted before beginning rehabilitation.

“…Board-certified vascular medicine physicians performed DUS of both lower extremities with an EnVisor C HD (Philips Medical System S.p.A, Monza, Italy) using a standardized examination protocol. 14 The iliac, femoral, and popliteal veins were examined first, then calf veins were evaluated with the patient seated and their legs vertical. Calf veins were studied using various views: anterior-medial, posterior, and posterior-lateral.…”

Relevance of immobility as a risk factor for symptomatic proximal and isolated distal deep vein thrombosis in acutely ill medical inpatients

2021

Immobility is a well-recognized risk factor for deep vein thrombosis (DVT) in surgical patients, whereas the level of DVT risk conferred by immobility is less defined in patients on medical wards. The aim of this study was to establish whether immobility and its duration are associated with the risk of DVT in acutely ill medical inpatients. We conducted a cohort study in acutely ill medical inpatients. Patients underwent whole leg ultrasound for suspected lower extremity DVT and were divided into two groups according to presence or absence of immobility, defined as total bed rest or sedentary without bathroom privileges. The endpoint was the detection of proximal DVT or isolated distal DVT (IDDVT). Among the 252 acutely ill medical inpatients with immobility (age 82.6 ± 10.3 years, female 63.9%), ultrasound showed 36 (14.3%) proximal DVTs and 39 (15.5%) IDDVTs, while there were 11 (4.4%) proximal DVTs and 26 (10.5%) IDDVTs among the 248 inpatients without immobility (age 73.6 ± 14.2 years, female 54.8%). The risk of proximal DVT was higher in immobile than in mobile patients (OR 3.59, 95% CI: 1.78–7.23, p = 0.0001), whereas the risk of IDDVT was similar between the two groups (OR 1.56, 95% CI: 0.92–2.66, p = 0.111). During the first 3 days of hospitalization, the frequency of all DVTs was similar in patients with and without immobility, but it was 0.26 ± 0.03 vs 0.18 ± 0.03, respectively, after 4 days. In conclusion, immobility for more than 3 days is a risk factor for proximal DVT in acutely ill medical inpatients.
