Image-guided treatment for blocked and narrowed blood vessels
Peripheral vascular disease can reduce blood flow to the arms or legs when arteries become narrowed or blocked. Interventional radiology offers minimally invasive ways to assess and treat selected vascular conditions using catheters, balloons, stents and other specialised techniques.
Dr. Yugal Goyal provides arterial and peripheral vascular interventions in Siliguri, including procedures for peripheral arterial disease, diabetic foot and limb salvage, aneurysms and selected vascular malformations.
Peripheral Arterial Disease (PAD) occurs when arteries supplying the limbs become narrowed or blocked, reducing blood flow. Symptoms may include leg pain while walking, weakness, coldness or changes in the skin.
In selected patients, endovascular treatment may be considered to improve blood flow without conventional open vascular surgery.
Balloon angioplasty uses a small balloon mounted on a catheter to widen a narrowed section of an artery. The balloon is positioned at the affected area and inflated to improve the passage for blood flow.
A stent is a small mesh tube that can be placed inside a narrowed artery to help maintain its opening. Stenting may be considered when appropriate based on the location and characteristics of the blockage.
Atherectomy uses a specialised device to remove or modify plaque within a narrowed artery. It may be considered in selected peripheral arterial disease cases.
Poor circulation can contribute to delayed wound healing and increase the risk of complications in people with diabetes.
When reduced arterial blood flow is contributing to a non-healing wound or threatened limb, endovascular revascularization may be considered to improve circulation.
The treatment approach depends on the location and severity of the arterial disease and the overall condition of the patient.
An aneurysm is an abnormal widening or bulging of a blood vessel. In selected cases, endovascular techniques can be used to treat aneurysms from inside the blood vessel.
Endovascular Aneurysm Repair (EVAR) uses a stent-graft delivered through the blood vessels to treat selected aortic aneurysms.
Thoracic Endovascular Aortic Repair (TEVAR) is an endovascular technique used for selected conditions affecting the thoracic aorta.
Whether EVAR or TEVAR is appropriate depends on the location, size and characteristics of the aneurysm and the patient's overall health.
Vascular malformations are abnormal formations or connections involving blood vessels. Some can cause swelling, pain, bleeding or other symptoms.
Embolization involves guiding a catheter to the abnormal vessels and delivering material to reduce or stop blood flow through them.
It may be used for selected vascular malformations, including certain arteriovenous malformations and hemangiomas.
Vascular interventions require detailed assessment of the blood vessels before treatment. Imaging helps determine the location and extent of narrowing, blockage or abnormal blood vessels and assists in planning the appropriate procedure.
The treatment selected depends on the patient's symptoms, vascular anatomy, imaging findings and overall clinical condition.
Peripheral arterial disease is a condition in which arteries supplying the limbs become narrowed or blocked, reducing blood flow.
Balloon angioplasty uses a small balloon to widen a narrowed section of an artery and improve blood flow.
A stent may be placed in selected cases to help keep a narrowed artery open after or alongside angioplasty.
Limb salvage refers to treatment aimed at preserving a threatened limb when poor blood flow or other complications put it at risk. In selected patients, improving arterial blood flow may be part of the treatment.
Embolization is a minimally invasive procedure in which material is delivered through a catheter to reduce or stop blood flow to a targeted area.
