What are some peripheral vascular diseases?

Peripheral vascular diseases (PVDs) are a group of conditions that affect the circulation of blood in your extremities, such as your hands, feet, and legs. They can narrow or block the arteries and veins to those parts of your body, which can lead to serious health implications. The most common types of PVDs include peripheral artery disease (PAD), venous insufficiency (VI), thromboembolism (TE), and aneurysms.

Peripheral artery disease is caused by a buildup of fatty deposits on the walls of arteries leading to them becoming narrowed or blocked. This restricts blood flow to organs beyond that point in the vessel network, including the legs and feet in particular. As a result it can cause cramping pain while walking – called claudication – fatigue due to lack of oxygen rich blood supply and even tissue loss due to ulcerations or sores forming on affected areas if left untreated for long enough periods.

Venous insufficiency is caused when valves inside veins aren’t functioning properly allowing backflow from downstream vessels rather than only flow moving towards the heart as it should be; this leads to varicose veins forming but more seriously medical issues such as deep vein thrombosis (DVT). Again symptoms may range from leg discomfort through swelling all the way up to ulcers forming if left untreated over extended amounts of time.

Thromboembolism results from obstructive material referred generally as ‘clots’ filling previously open space within vessels; this obstructive nature brings with it cut off further circulation resulting in secondary tissue death if not treated with timely interventions such medication thinning agents e.g Warfarin among others dietary changes etc..   Finally aneurysms are enlargement either arterial causing its weakening wall structure leading eventually into rupture events potentially fatal ones too! Warning signs here being chest/abdominal pains associated at times lastly ruptures presenting themselves with sudden dramatic life-threatening shock episodes demanding process primary care attention immediately!

In conclusion PVDs come in various forms affecting people globally each year both young & old alike so early detection & treatment always advisable regardless whether sites superficial far away internal/deep seated ones given their potential equally grave outcomes best avoided then monitored maintained religiously thereafter via closest healthcare providers!
