  2. Trousseau sign of malignancy - Wikipedia

    en.wikipedia.org/wiki/Trousseau_sign_of_malignancy

    Trousseau's syndrome is a rare variant of venous thrombosis that is characterized by recurrent, migratory thrombosis in superficial veins and in uncommon sites, such as the chest wall and arms. This syndrome is particularly associated with pancreatic, gastric and lung cancer and Trousseau's syndrome can be an early sign of cancer [ 2 ] [ 3 ...

  3. Transmural pressure - Wikipedia

    en.wikipedia.org/wiki/Transmural_pressure

    Transmural pressure is the difference in pressure between two sides of a wall or equivalent separator. According to myogenic theory smooth muscle contract in response to increased transmural pressure and relax to decreased transmural pressure For body vasculature or other hollow organs, see Smooth muscle#External substances

  4. Superior vena cava syndrome - Wikipedia

    en.wikipedia.org/wiki/Superior_vena_cava_syndrome

    Non-malignant causes are increasing in prevalence due to expanding use of intravascular devices (such as permanent central venous catheters and leads for pacemakers and defibrillators), which can result in thrombosis. [2] Other non-malignant causes include benign mediastinal tumors, aortic aneurysm, infections, and fibrosing mediastinitis. [3]

  5. Thrombosis - Wikipedia

    en.wikipedia.org/wiki/Thrombosis

    Cancer-associated thrombosis can result from: (1) stasis, i.e., direct pressure on blood vessels by the tumor mass, poor performance status, and bed rest following surgical procedures; (2) iatrogenic, due to treatment with antineoplastic medications; and (3) secretion of heparanase from malignant tumors that results in degradation of endogenous ...

  6. Thrombus - Wikipedia

    en.wikipedia.org/wiki/Thrombus

    Propagation of a thrombus occurs towards the direction of the heart and involves the accumulation of additional platelets and fibrin. This means that it is anterograde in veins or retrograde in arteries. Embolization occurs when the thrombus breaks free from the vascular wall and becomes mobile, thereby traveling to other sites in the vasculature.

  7. Warburg effect (oncology) - Wikipedia

    en.wikipedia.org/wiki/Warburg_effect_(oncology)

    Otto Warburg postulated this change in metabolism is the fundamental cause of cancer, [8] a claim now known as the Warburg hypothesis. Today, mutations in oncogenes and tumor suppressor genes are thought to be responsible for malignant transformation , and the Warburg effect is considered to be a result of these mutations rather than a cause.

  8. Vein - Wikipedia

    en.wikipedia.org/wiki/Vein

    Veins (/ v eɪ n /) are blood vessels in the circulatory system of humans and most other animals that carry blood towards the heart.Most veins carry deoxygenated blood from the tissues back to the heart; exceptions are those of the pulmonary and fetal circulations which carry oxygenated blood to the heart.

  9. Arterial stiffness - Wikipedia

    en.wikipedia.org/wiki/Arterial_stiffness

    Arterial stiffness may also affect the time at which pulse wave reflections return to the heart. As the pulse wave travels through the circulation it undergoes reflection at sites where the transmission properties of the arterial tree change (i.e. sites of impedance mismatch). These reflected waves propagate backward towards the heart.
