Vertebral artery dissection is one of the two types of cervical artery dissection.The other type, carotid artery dissection, involves the carotid arteries.Vertebral artery dissection is further classified as being either traumatic (caused by mechanical trauma to the neck) or spontaneous, and it may also be classified by the part of the artery involved: extracranial (the part outside the skull ...
Arterial dissections become life-threatening when growth of the false lumen prevents perfusion of the true lumen and the related end organs. For example, in an aortic dissection, if the left subclavian artery orifice were distal to the origin of the dissection, then the left subclavian would be said to be perfused by the false lumen, while the left common carotid (and its end organ, the left ...
This prevents the heart from filling normally with blood. This can critically decrease the amount of blood that is pumped from the heart, causing obstructive shock , which can be lethal. The removal of the excess fluid reverses this dangerous process, and is often the first treatment for cardiac tamponade due to its speed.

Intended for use by medical, dental and medical science students, the video teaching aid uses simple language and high quality images. The authors claim: "Each minute of the finished product took twelve hours to produce: five in creating the script, five in making the shots, and two in post-production." [2]
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 ...
Vessel harvesting is a surgical technique that may be used in conjunction with a coronary artery bypass graft (CABG). For patients with coronary artery disease, a vascular bypass may be recommended to reroute blood around blocked arteries to restore and improve blood flow and oxygen to the heart.
The proximal part of left subclavian is blocked (shaded artery). This prevents antegrade ("forward") flow to the left arm and left vertebral. As a result, flow in the left vertebral is retrograde ("backwards") towards the left arm. Flow to the brain and circle of Willis is via antegrade right and left carotid and right vertebral arteries.
