What Is Peripheral Vascular Disease and How Do Minimally Invasive Interventions Treat It?

Understanding Peripheral Vascular Disease

Peripheral vascular disease , most commonly manifesting as lower extremity arterial obstruction, is a serious condition that, if left untreated, may lead to limb amputation or even sudden cardiac death. Among individuals over the age of 60, the incidence of PVD is reported to be around 10%, and this number increases to approximately 20% for arteriosclerosis obliterans in those over 65.

PVD refers to disorders affecting blood vessels outside of the heart and brain, encompassing diseases of the arteries, veins, and lymphatic system. The most common underlying cause is atherosclerosis, where fatty deposits accumulate on the inner walls of blood vessels and combine with calcium and fibrous tissue to form hardened plaques that narrow or block vascular channels. Other contributing factors include thrombosis, diabetes, hypertension, hyperlipidemia, vasculitis, infections, and congenital vascular abnormalities.

Minimally Invasive Interventions: A Key Approach to Treating PVD

While conventional medical therapy often yields limited results and traditional surgery is highly invasive, the advancement of interventional medicine has made minimally invasive procedures the preferred, first-line treatment for lower extremity vascular obstructions.

Advanced Imaging Guidance: Procedures are performed under the guidance of advanced technologies such as angiography, CT, MRI, or ultrasound.

Targeted Precision: Using specialized tools like puncture needles and catheters, physicians access affected vessels to carry out diagnosis and treatment with minimal trauma.

Stent Implantation: Among various interventional techniques, stent placement remains one of the most commonly employed methods to restore healthy blood flow and preserve limb function.
