Erythrocyte shape change in contracted venous thrombi extracted from patients with deep vein thrombosis. (A) A representative scanning electron microscopy image of a venous thrombus showing formation of polyhedrocytes and intermediate shaped polyhedral-like RBCs. Scale bar is 30 µm. (B) Percentage of biconcave, intermediate and polyhedral erythrocytes in human venous thrombi (n = 9).
