New considerations in the diagnosis and therapy of deep vein thrombosis
1Family Medicine Residency Program, Moses H. Cone Health System, Greensboro, NC, USA.
Insights
Iliofemoral deep vein thrombosis (IFDVT) is a serious condition. Early treatment with catheter-directed thrombolysis may preserve valve function and reduce long-term complications like postthrombotic syndrome.
Area of Science:
- Vascular Medicine
- Hematology
Background:
- Venous thromboembolic disease is a significant medical issue.
- Iliofemoral deep vein thrombosis (IFDVT) is an underrecognized manifestation.
- Virchow's triad (stasis, hypercoagulability, intimal injury) underlies thrombosis.
Observation:
- This case report details a patient with atraumatic iliofemoral DVT.
- Diagnostic considerations for IFDVT are presented.
- Therapeutic strategies for IFDVT are illustrated.
Findings:
- Catheter-directed thrombolytic therapy shows efficacy in IFDVT resolution.
- Early thrombolysis may preserve venous valve function.
- Reduced incidence of postthrombotic syndrome is associated with early lysis.
Implications:
- Timely diagnosis and treatment of IFDVT are crucial.
- Catheter-directed thrombolysis offers a viable treatment option.
- Preserving valve function can mitigate long-term sequelae of DVT.
Abstract:
The cause of thrombosis is often unknown but is universally ascribed to part of Virchow's triad: stasis, hypercoagulability, and intimal injury. Venous thromboembolic disease is a common and costly medical problem, with iliofemoral deep vein thrombosis (IFDVT) being a less common but often underestimated presentation of this condition. Treatment options for deep vein thrombosis (DVT) have expanded in recent years and now include systemic anticoagulation, thrombolytic therapy, and surgery. Several studies have shown the efficacy of catheter-directed thrombolytic therapy in resolution of IFDVT. There is also growing evidence that early lysis is more likely to preserve valve function leading to a decrease in the incidence of postthrombotic syndrome, which is a known long-term complication of DVT and IFDVT. The following case report describes a patient, without malignancy, who had an atraumatic iliac and femoral DVT and illustrates the diagnostic considerations and therapy of a patient with iliofemoral DVT.
