Venous Thromboembolism Associated with Uterine Fibroids: A Review of Reported Cases

<b>Background/Objectives</b>: The most prevalent benign tumors in women are uterine fibroids. Most patients-more than half-do not exhibit any symptoms, but the most common clinical signs include irregular uterine bleeding, pelvic pain, gastrointestinal problems, increased frequency of urination, and, in some cases, infertility. Venous thromboembolism is a very rare consequence, especially when significant uterine fibroids are present. This syndrome usually develops because of pelvic vascular systems being compressed, which causes venous stasis. Pharmacological treatment, minimally invasive procedures, and surgical techniques are examples of therapy alternatives. The purpose of this study is to present, compare, and potentially elucidate the underlying mechanisms of VTE development in fibroids. <b>Methods</b>: we have synthesized findings from 24 documented instances of venous thromboembolism (VTE) linked to uterine fibroids. <b>Results</b>: the principal mechanism underlying thromboembolic events was identified as the mechanical compression of pelvic venous structures due to mass effect. Additionally, we recognized other pertinent risk factors, including oral contraceptive use, May-Thurner syndrome, myomatous erythrocytosis, and intravenous leiomyomatosis. None of the reviewed case reports provided evidence of confirmed inherited thrombophilia in the patients under investigation. The femoral and popliteal veins, primarily in the left leg, were most frequently impacted by thrombosis and the ensuing blockage. Imaging techniques confirmed that individuals suffered pulmonary embolisms in half of the cases. When the right treatment was given as soon as possible, most of VTEs had favorable outcome. In almost half of the cases examined, the patient had a hysterectomy. Since all symptoms were alleviated and the chance of additional thromboembolic consequences was reduced, this treatment strategy turned out to be the most successful. <b>Conclusions</b>: Clinicians should maintain a low threshold for venous imaging in women with large pelvic masses and unilateral limb symptoms. Despite being uncommon, VTE associated with UFs can cause serious morbidity. Mechanical venous compression is the main mechanism, which is often exacerbated by additional prothrombotic variables. Clinicians should maintain a low threshold for venous imaging in women with significant pelvic masses and unilateral limb symptoms, look for concurrent thrombophilia, and investigate early surgical consultation to address compressive etiologies when VTE is still unexplained. It would be simpler to ascertain the actual incidence and pinpoint risk variables that can be altered with standardized reporting of fibroid-associated VTE and prospective registries.
