Final answer:
Immediate intervention for thrombophlebitis is typically necessary due to the risk of serious complications. Removal of superficial veins can be performed without impairing circulation thanks to vein anastomoses. Patients with varicose veins are at a higher risk for developing clots.
Step-by-step explanation:
The statement that immediate intervention for thrombophlebitis is not necessary is generally false. Thrombophlebitis refers to inflammation of the veins due to a thrombus or clot. If untreated, it can lead to serious complications such as a pulmonary embolism, where the clot dislodges and travels to the lungs, which can be life-threatening. Therefore, immediate medical intervention is usually required to manage the condition and prevent complications.
Surgical removal of varicose veins is often considered when they cause symptoms or complications, such as thrombophlebitis. Due to the presence of anastomoses—connections between veins—for the smaller and more superficial veins, removal does not typically impair the circulation. Patients with varicose veins do have a greater risk of developing a thrombus, underlining the importance of careful monitoring and potential intervention.
