Angiography is a medical imaging technique of high accuracy used to detect blockages in the blood vessels. The minimally invasive technique involves injecting a contrast substance into the arteries to be visible in X-ray. When a patient walks in with complaints such as chest pain, cramping leg pain or mini-stroke like symptoms the Physician might refer to a radiologist to perform Angiography to find the root cause. Depending on the organ that is expected to have the blockage issue the Angiography is performed on the arteries connecting to that particular organ. On this basis, the classifications are Cerebral, Coronary, Pulmonary, Renal, Fluorescein, Celiac and mesenteric angiography. The radiographic contrast is injected and the X-ray is performed to produce images called the angiogram to pinpoint the location of the artery/vein blockage and perform further diagnosis. Typically the procedure lasts around half an hour and is not very complicated or uncomfortable, as local anaesthesia will be administered before the procedure. Catheter angiography is performed using a thin hollow tube to administer the contrast medium to obtain very clear angiogram to study the arteries. The radiologists examine the angiogram and share the interpreted results with the referring physician to pursue further step as required. No major complications are expected with the procedure except for some bruising on the access site or swelling under the skin known as hematoma and the medical personnel will watch out for any of these symptoms and treat it properly post procedure and the patient is good to go.
