Because of its similarities to deep vein thrombosis (DVT), May–Thurner syndrome is rarely diagnosed amongst the general population. In this condition, the right iliac artery sequesters and compresses the left common iliac vein against the lumbar section of the spine, [5] resulting in swelling of the legs and ankles, pain, tingling, and/or numbness in the legs and feet. [6]
Pain radiating up into the leg, [1] behind the shin, and down into the arch, heel, and toes; Hot and cold sensations in the feet; A feeling as though the feet do not have enough padding; Pain while operating automobiles; Pain along the posterior tibial nerve path; Burning sensation on the bottom of foot that radiates upward reaching the knee
A gel is used with the probe to make a good acoustic impedance contact. The training and expertise of the examiner is important because of the many technical complications that can present. Venous anatomy, for example, is not constant; for example, a patient's vein layout of the right limb is not identical to that of the left limb. [citation ...
This valvular incompetence combined with persistent venous obstruction from thrombus increases the pressure in veins and capillaries. Venous hypertension induces a rupture of small superficial veins, subcutaneous hemorrhage [7] and an increase of tissue permeability. That is manifested by pain, swelling, discoloration, and even ulceration. [8]
If the impaired vein function causes significant symptoms, such as swelling and ulcer formation, it is referred to as chronic venous disease. [3] It is sometimes called chronic peripheral venous insufficiency and should not be confused with post-thrombotic syndrome in which the deep veins have been damaged by previous deep vein thrombosis.
The signs and symptoms of NCS are all derived from the outflow obstruction of the left renal vein. The compression causes renal vein hypertension, leading to hematuria (which can lead to anemia) [4] and abdominal pain (classically left flank or pelvic pain). [5] The abdominal pain may improve or worsen depending on positioning. [5]
The popliteal vein is a vein of the lower limb. It is formed from the anterior tibial vein and the posterior tibial vein. It travels medial to the popliteal artery, and becomes the femoral vein. It drains blood from the leg. It can be assessed using medical ultrasound. It can be affected by popliteal vein entrapment.
Pelvic congestion syndrome, also known as pelvic vein incompetence, is a long-term condition believed to be due to enlarged veins in the lower abdomen. [1] [7] The condition may cause chronic pain, such as a constant dull ache, which can be worsened by standing or sex. [1] Pain in the legs or lower back may also occur. [1]
