KIMS Hospitals Thane has successfully treated a complex case of Peripheral Artery Disease (PAD) in an elderly patient using advanced excimer laser atherectomy. This achievement marks a significant step forward in minimally invasive vascular care.
High-Risk Patient Managed with Minimally Invasive Approach
An 88-year-old woman with a history of diabetes, hypertension, and prior stroke presented with severe rest pain and gangrene in her toe. Imaging subsequently revealed a major arterial blockage in the leg.
To address this, clinicians performed a minimally invasive endovascular procedure using the Philips Excimer 300 laser system along with a specialised laser atherectomy catheter. As a result, they successfully cleared the blockage and restored blood flow. The patient experienced rapid relief and was discharged the next day, walking comfortably.
How Excimer Laser Atherectomy Works
This advanced system uses a cool ultraviolet (308 nm) laser to precisely break down plaque within blood vessels. Unlike conventional techniques, it effectively treats complex and long-standing blockages while preserving surrounding healthy tissue.
Importantly, the technology is particularly useful in managing chronic total occlusions (CTOs), where arteries are completely blocked and often resistant to standard treatments.
Limitations of Conventional Techniques
Traditionally, angioplasty and stenting widen blocked arteries and maintain blood flow using supportive stents. However, in complex or heavily calcified lesions, these approaches may offer limited durability.
To overcome this, mechanical atherectomy methods—such as directional, orbital, and rotational devices—have been used to physically remove plaque. Nevertheless, these techniques can increase procedural complexity and carry risks, including distal embolization and vessel injury.
Laser Atherectomy Offers Safer, Targeted Treatment
In contrast, excimer laser atherectomy provides a more precise and controlled alternative. It uses ultraviolet energy to vaporise soft plaque and disrupt calcium deposits at a molecular level. Consequently, it enables targeted removal of blockages while minimising damage to surrounding tissue.
Moreover, this approach significantly reduces the risk of distal embolization and vessel dissection, making it particularly advantageous for elderly and high-risk patients.
Customisable Technology Enhances Outcomes
Another key advantage lies in its customisable energy delivery. Physicians can adjust laser settings based on the type and severity of the blockage, thereby improving procedural precision. This flexibility not only reduces complexity but also enhances overall clinical outcomes.
Globally, excimer laser technology has been used in over 600,000 procedures, reinforcing its reliability in managing complex vascular conditions.
Expert Insights on Clinical Benefits
As per the press release, Dr. Ritesh Gaikwad, Consultant Vascular Surgeon at KIMS Hospitals Thane, highlighted that the technology allows clinicians to remove blockages layer by layer with high precision, thereby improving success rates even in challenging cases.
Similarly, Dr. Vinit Paliwal emphasised that the ability to tailor energy delivery makes the procedure safer and more effective, ultimately improving limb salvage outcomes in patients with severe vascular disease.
A Step Forward in Minimally Invasive Vascular Care
Laser atherectomy is increasingly emerging as a preferred option for patients who are not ideal candidates for open surgery. It offers shorter hospital stays, faster recovery, and reduced procedural risks.
Overall, the successful use of this cutting-edge technology positions KIMS Hospitals Thane among leading centres adopting advanced endovascular innovations to improve patient care.
