Rabbit is a complex character. He is shown to value organization and order. However he is easily frustrated, often due to the chaos caused (unintentionally) by his friends, mainly Tigger. Rabbit's greatest concern is his garden, which he works on constantly, and he is easily annoyed when it is tampered with.
Occlusion is consistent with an acute or chronic thrombus. Findings of intraluminal septation, webs, or stenoses are consistent with a healed or remote deep venous thrombosis. In chronic DVT, recanalization can result in a linear filling defect in the vein, sometimes termed the tram-track pattern.
While not likely to be sudden and bilateral--this is potentially life threatening. Essentially a DVT is a blood clot that spontaneously forms in the venous system (the vessels that bring blood from the muscles back to the heart). These clots can form from multiple conditions--the two most common are a thrombophilia (or blood clotting disorder) or an undiagnosed cancer.
