Pulmonary veno-occlusive disease (PVOD) is a rare form of pulmonary hypertension caused by progressive blockage of the small veins in the lungs. [2] The blockage leads to high blood pressures in the arteries of the lungs, which, in turn, leads to heart failure.
Chronic venous insufficiency (CVI) is a medical condition characterized by blood pooling in the veins, leading to increased pressure and strain on the vein walls. [1] The most common cause of CVI is superficial venous reflux, which often results in the formation of varicose veins, a treatable condition. [2]
Pulmonary hypertension (PH or PHTN) is a condition of increased blood pressure in the arteries of the lungs. [7] Symptoms include shortness of breath, fainting, tiredness, chest pain, swelling of the legs, and a fast heartbeat. [7] [1] The condition may make it difficult to exercise. [7] Onset is typically gradual. [8]
This is a shortened version of the seventh chapter of the ICD-9: Diseases of the Circulatory System. It covers ICD codes 259 to 282 . The full chapter can be found on pages 215 to 258 of Volume 1, which contains all (sub)categories of the ICD-9.
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.
Benign hypertension or benign essential hypertension are medical terms now considered obsolete, but once used to describe mild to moderate hypertension (high blood pressure). These historical terms are considered misleading, [1] as hypertension is never benign. Coonsequently, the terms have fallen out of use (see history of hypertension).
According to ICD-10, hypertensive heart disease (I11), and its subcategories: hypertensive heart disease with heart failure (I11.0) and hypertensive heart disease without heart failure (I11.9) are distinguished from chronic rheumatic heart diseases (I05-I09), other forms of heart disease (I30-I52) and ischemic heart diseases (I20-I25).
Peripheral vascular disease-ulcer. Treatment varies based on the type of vascular disease being treated. In treating renal artery disease, a 2014 study indicates that balloon angioplasty can improve diastolic blood pressure and potentially reduce antihypertensive drug requirements. [30]
