Heart blood vessel and thromboembolic syndrome are caused by the necrosis and disintegration of digestive system tumors, as well as the infiltration and destruction of tissues by tumors, which release coagulant substances into the blood, activating the coagulation system and leading to blood clotting and thrombosis, resulting in heart blood vessel damage.

1. Thrombophlebitis is often associated with pancreatic cancer, stomach cancer, and colorectal cancer.

2. Lymphatic edema is seen in colorectal cancer and metastatic colorectal cancer, caused by tumor compression or obstruction of lymphatic vessels. It manifests as localized edema in the corresponding lymphatic drainage area, usually unilateral, sometimes resembling elephantiasis.

3. Raynaud's phenomenon occurs in colorectal cancer and pancreatic cancer, primarily presenting as acute limb ischemia, such as sequential whitening, cyanosis, and flushing of the extremities. Some cases may exhibit persistent cyanosis.

4. Non-bacterial thrombotic verrucous endocarditis can be observed in stomach cancer and pancreatic cancer. Vegetative thrombotic deposits adhere to the endocardium, mostly affecting the left heart valves, and sometimes the tricuspid valve. Thrombus detachment leads to multi-organ embolism. {|103|}
