Phlegmasia cerulea dolens is a devastating complication of massive deep venous thrombosis, which is clinically characterized by massive lower extremity tissue edema and subsequent arterial insufficiency. These experiments evaluated the local tissue effects of acute global venous obstruction combined with partial arterial ischemia. Experiments were performed to assess the effects of heparin on the cytokine response to simultaneous venous and partial arterial obstruction. Murine hind limbs were subjected to conditions of unilateral venous occlusion and partial tourniquet limb ischemia, which was confirmed by laser Doppler imaging (LDI). Mice underwent either hind limb venous obstruction with intravenous unfractionated heparin (200IU/kg) or intravenous saline 5min before venous occlusion. Sham-treated mice were subjected to anesthesia alone without venous occlusion. After 3hr, the mice were killed and tissue was harvested for measurement of edema (wet to dry weight ratio, W/D), muscle viability, indices of local thrombosis (thrombin-antithrombin complex [TAT]), and cytokine analysis for growth-related oncogene-1 (GRO-1) and interleukin-6 (IL-6, protein via enzyme-linked immunoassay and mRNA via reverse transcriptase polymerase chain reaction). Bleeding time and volume were documented in saline- and heparin-treated mice to confirm systemic anticoagulation. Administration of intravenous heparin resulted in a marked increase in bleeding time and volume. LDI confirmed venous obstruction and ongoing arterial inflow. Venous obstruction resulted in severe visible edema that correlated with a significantly higher W/D ratio but was not associated with a significant decrease in muscle viability. GRO-1 and IL-6 protein and mRNA levels were significantly elevated in the venous occlusion group compared to sham. Heparin therapy significantly decreased TAT3 levels but did not alter the profile of GRO-1 or IL-6 protein levels seen with venous occlusion. Venous occlusion with partial ischemia induces a unique and potent local cytokine expression. Heparin therapy did not ameliorate the cytokine response. These data indicate that heparin therapy does not modulate the cytokine response to venous obstruction.

Phlegmasia cerulea dolens is a rare but serious complication of deep venous thrombosis, which can lead to arterial compromise, tissue ischemia, and gangrene. It typically presents in an elderly population often with coexistent malignancy. There have been no reported cases in the ambulatory pediatric population. The authors report a case of a 5-year-old girl who presented with acute, extensive left lower extremity deep venous thrombosis resulting in phlegmasia cerulea dolens. Pharmacologic and mechanical interventions as described in the adult population were utilized. This case demonstrates that an aggressive, multimodal approach to phlegmasia cerulea dolens can be employed in the pediatric population and result in successful limb salvage.

Vascular manifestations are not rare in systemic lupus erythematosus and, in most cases, are associated with antiphospholipid antibodies. Phlegmasia cerulea dolens is an unusual and severe complication of deep venous thrombosis of the lower limbs, which has a high mortality rate. In the literature, only two cases of phlegmasia cerulea dolens associated with primary antiphospholipid syndrome have been reported, but none associated with systemic lupus erythematosus. We report one case of phlegmasia cerulea dolens with rapid evolution to death in a patient with systemic lupus erythematosus in the remote postpartum period.

Phlegmasia cerulea dolens (PCD) is a rare but limb-threatening complication of deep vein thrombosis. We report a case of a 76-year-old man with recent splenic trauma and inferior vena cava (IVC) filter placement, who developed bilateral lower extremity PCD. Utilizing an endoluminal approach, the patient underwent mechanical thrombectomy and thrombolysis through bilateral infusion catheters placed antegrade from bothpopliteal veins. Clot lysis and return of palpable pedal pulses occurred within 24 hours. We demonstrate that the endoluminal management of this disease may be cautiously applied to the trauma patient, and that the judicious use of thrombolytic therapy can be beneficial even in the patient with a high potential for hemorrhage.

Ankylosing spondylitis (AS) is an inflammatory rheumatic disease. Phlegmasia cerulea dolens is a severe form of deep vein thrombosis characterized by swelling, pain, and bluish discoloration. Treatment delay may cause venous gangrene, tissue ischemia, limb loss or death. Here, we present an AS case who presented with phlegmasia cerulea dolens and treated by catheter-directed thrombolysis.

Phlegmasia cerulea dolens (PCD) is one of the most critical disorders of acute deep vein thrombosis in that it can cause permanent disability secondary to the compartment syndrome. Although several etiological factors have been proposed, PCD after coronary artery bypass surgery is extremely rare and its definitive pathophysiology is still under debate. We herein present a case of PCD that resulted in the compartment syndrome after coronary artery bypass surgery. Early recognition and decompression of PCD are crucial for saving the affected limbs.

Phlegmasia cerulea dolens (PCDs) is a rare and serious complication of massive deep venous thrombosis of the lower extremities, which has a high mortality rate. It is characterized by the sudden onset of severe leg pain, massive edema, cyanosis, venous gangrene, compartment syndrome and arterial compromise, often followed by pulmonary embolism and death. We report one case of a long distance driver who presented with PCDs, complicated by fatal pulmonary embolism.

Phlegmasia cerulea dolens (PCD) is a rare entity that refers to a painful, edematous, and cyanotic limb due to a massive deep vein thrombosis (DVT). Due to its rarity, the exact incidence is unknown; however, it is vital that the military health care provider recognize it as the condition can be limb and life threatening. Due to the recent increase in combat-related operations, DVT has had a steady increase in the past 10 years in the military population, and as such has become a condition of special interest and surveillance in the armed forces. PCD is part of a spectrum that consists of distal DVT, more proximal DVT, phlegmasia alba dolens (PAD), and finally PCD with venous gangrene. PAD is an early stage of PCD, in which although there is a massive DVT present, the collateral and superficial circulation are not yet involved; this in turn results in a painful, edematous, white leg. PCD is preceded by PAD in approximately 50% to 60% of the cases. PCD has an amputation rate of up to 50% and a mortality rate of up to 40%. The patient will present with a swollen, cyanotic, painful leg that may or may not show signs of venous gangrene. In PCD, the collateral circulation is not spared and this causes severe congestion and fluid sequestration in the limb leading to venous hypertension. This can lead to circulatory shock and arterial insufficiency as it progresses. We review a case report of a 66-year-old woman that presented to small community army hospital after a 26-hour bus drive with knee pain and leg swelling. The diagnosis of PCD was made after Doppler ultrasonography showed bilateral iliofemoral, common, femoral, and saphenous veins thrombosis. The patient's left lower extremity was discolored, tender, and swollen, although it had not progressed to venous gangrene or dermal necrosis. While the management of PCD is not standardized due to the rarity of the condition, several options are available. These options include anticoagulation, minimally invasive procedures such as catheter-directed thrombolysis, or more invasive procedures such as surgical thrombectomy. In the active duty military population, clot reduction techniques would be preferred to long-standing anticoagulation, as the morbidity is greater with anticoagulation alone as well as the probability of major hemorrhage. Besides pulmonary embolism, which is a complication in up to 30% of the patients with PCD, one must keep in mind the extent and duration of the thrombus when choosing a treatment method, as these factors are directly related to the morbidity associated with post-thrombotic syndrome. Functional impairment after a massive DVT or PCD is an important factor that must be kept in mind for troop readiness.

Nephrotic syndrome is a well-known risk factor of deep vein thrombosis (DVT). Catheter-related DVT under the setting of nephrotic syndrome may be presented as a more fulminant form, phlegmasia cerulea dolens. Phlegmasia cerulea dolens may lead to severe obstruction of venous drainage of the extremities and presents with compartment syndrome that impairs arterial perfusion. Aggressive management with thrombolysis and/or thrombectomy are considered with simultaneous anticoagulant treatment.

Phlegmasia cerulea dolens (PCD) is a rare entity that is associated with significant morbidity and mortality, including limb ischemia and pulmonary embolism. Point-of-care ultrasound (POCUS) can expedite the diagnosis, leading to earlier life- and limb-saving treatment. Although primarily used for assessing for the presence of deep venous thrombosis, in the appropriate clinical setting POCUS can also be used to diagnosis PCD as well as to distinguish between venous and arterial occlusion, which can lead to a difference in management. We present a case of phlegmasia cerulea dolens after mild trauma in a patient with an underlying hypercoagulability disorder diagnosed by an emergency physician using POCUS, which expedited treatment with catheter-directed thrombolytic therapy.
