When a blood vessel supplying the tumor has been selected, alternating doses of the chemotherapy dose and of embolic particles, or an infusion of embolic particles containing the chemotherapy agent, are injected through the catheter . The physician removes the catheter and access sheath, applying pressure to the entry site to prevent bleeding.
Vesicouterine fistulas occur most commonly after lower segment caesarean sections (about 83-93% of cases). [2] The possible mechanisms by which vesicouterine fistulas occur following caesarean sections include undetected bladder injury during caesarean section, inadvertent placement of a suture through the bladder during the repair of the uterus and abnormal blood vessel connections following ...
The carotid arteries are major blood vessels in the neck that branch into smaller vessels called the external and internal carotid arteries. [3] In carotid artery dissection, a tear in the arterial wall allows blood to flow between the layers of the artery, leading to potential narrowing, reduced blood flow, or clot formation, which may cause a ...
GPA treatment depends on the severity of the disease. [8] Severe disease is typically treated with a combination of immunosuppressive medications such as rituximab or cyclophosphamide and high-dose corticosteroids to control the symptoms of the disease and azathioprine, methotrexate, or rituximab to keep the disease under control.
Stretching, occupational and physical therapy are common non-invasive approaches used in the treatment of TOS. The goal of stretching is to relieve compression in the thoracic cavity, reduce blood vessel and nerve impingement, and realign the bones, muscles, ligaments, or tendons that are causing the problem.

Cervical artery dissection has been noted to be a common cause of young adult strokes, with some sources indicating a prevalence of up to 20% in this young adult population with annual incidence rates between 2.6 and 2.9 per 100,000, although these incidences may be misleading with true incidences being higher because clinical presentations can vary, many being minor or self-limited, and thus ...
Globally, head and neck cancer accounts for 650,000 new cases of cancer and 330,000 deaths annually on average. In 2018, it was the seventh most common cancer worldwide, with 890,000 new cases documented and 450,000 people dying from the disease. [12] The risk of developing head and neck cancer increases with age, especially after 50 years.
Raynaud’s disease is a rare peripheral vascular syndrome that narrows blood vessels, generally in the hands and feet, due to cold or stressful emotion. [8] It is recognized by the reduction of blood flow to fingers and toes with periodic spasm and results in a drastic color change to white or blue.
