Prolonged chylothorax is a rare, life-threatening, pleural effusion that may be encountered in the setting of trauma. Conservative treatment may be successful and is the traditional approach in cases of limited chyle output. Early surgical intervention is required in cases with large refractory chyle output, but may be associated with substantial morbidity and mortality. Percutaneous thoracic duct embolization is an uncommon, minimally invasive, safe and effective treatment alternative. We report a case of successful thoracic duct embolization to treat large-volume chylothorax due to blunt trauma.

Acrocyanosis is symmetric, painless, discoloration of different shades of blue in the distal parts of the body that is marked by symmetry, relative persistence of the skin color changes with aggravation by cold exposure, and frequent association with local hyperhidrosis of hands and feet. Described over a century ago and despite seeming familiarity, it remains a poorly understood condition that shares much in clinical presentation with other conditions characterized by skin color changes in the distal parts of the body. The diagnosis remains mostly clinical, and pathological mechanisms vary suggesting that acrocyanosis may not be a single entity. We performed an extensive literature review to summarize existing knowledge about the demographics, pathology, diagnosis, and treatment of this condition.

Introduction: To determine the relationship between fibrin D-dimer levels, symptom duration, and thrombus volume, consecutive patients with incident deep venous thrombosis (DVT) were evaluated. Methods: In a cross-sectional study design, patient symptom onset was determined by careful patient questioning. Venous thrombosis was confirmed by compression duplex ultrasonography. Thrombus volume was estimated based on patient’s femur length using a forensic anthropology method. Fibrin D-dimer was measured by latex immunoassay. Results: 72 consecutive patients with confirmed leg DVT agreed to participate. The median symptom duration at the time of diagnosis was 10 days. The median D-dimer concentration was 1050 ng/dL. The median thrombus volume was 12.92 cm 3 . D-Dimer levels correlated with estimated thrombus volume (P < .0006 CI 0.12-0.41; R 2 adjusted = .15) but not symptom duration, patient’s age, or gender. Conclusions: Despite varying symptom duration prior to diagnosis, fibrin D-dimer remains a sensitive measure of venous thrombosis and correlates with thrombus volume.
