Harkanwar Gill on Interventional Radiology, Physician Leadership, and Medical Education

Many patients first encounter interventional radiology after a surgeon, oncologist, or another specialist explains that a condition may be treated without traditional open surgery. The idea can be surprising: a physician may be able to reach and treat a blood vessel, blood clot, or tumor through a small access point while using medical imaging for guidance. For appropriate patients, these techniques may reduce the need for large incisions and support a shorter recovery.

Dr. Harkanwar Gill, a physician whose experience includes general surgery, radiology, and nuclear medicine, focuses clinically on vascular and interventional radiology. His work has reinforced a central lesson: technical precision is only one part of effective care. Patients also need clear explanations, realistic expectations, and the confidence to participate in decisions about their treatment.

What Is Interventional Radiology?

Interventional radiology is a medical specialty that uses imaging technologies, such as CT, MRI, ultrasound, and fluoroscopy, to guide procedures inside the body. Depending on the condition and the patient’s individual needs, an interventional radiologist may use small catheters, wires, needles, or probes to diagnose or treat disease through a small access point.

The specialty has expanded significantly since its emergence in the late 1960s. New devices, imaging systems, and treatment methods have created minimally invasive options across vascular care, cancer treatment, and other areas of medicine. Gill believes patients benefit most when these options are explained in the context of all available treatments, including their potential benefits, limitations, risks, and alternatives.

How Harkanwar Gill Explains Minimally Invasive Procedures to Patients

Medical language can make an already stressful diagnosis feel even more difficult. Gill’s approach begins by replacing jargon with a visual explanation. He often reviews a patient’s CT scan or MRI with them so they can see the medical issue and understand what the care team is trying to address.

“One of the key responsibilities in medicine is to break down the complexity of a patient’s condition and communicate it effectively without relying on complicated medical terminology,” Gill said. “Medical jargon can easily confuse patients and their families, making it difficult for them to make informed decisions about their care.”

After reviewing the images, Gill explains how the proposed image-guided procedure works. He describes the instruments involved, the type of sedation or anesthesia that may be used, the expected recovery, alternative treatment options, and the potential risks. Because procedures and recovery plans vary, he emphasizes that recommendations must be tailored to the patient and the condition.

“I strive to treat every patient as I would a family member,” he said, “ensuring that they are fully informed and comfortable with the decision-making process, always with the goal of achieving the best outcome.”

That conversation can be especially important for people who have never heard of interventional radiology. Gill frequently meets patients who are surprised that a minimally invasive option exists. Their questions reinforce his belief that greater public awareness could help more people have informed conversations with their healthcare teams.

Advances in Vascular and Interventional Radiology

Gill points to the treatment of blood clots as one example of how interventional radiology has evolved. Blood-thinning medication remains an important treatment for many patients with pulmonary embolism or deep vein thrombosis. In selected cases, however, physicians may also use catheter-based therapies or aspiration devices to remove or reduce clot burden. The appropriate approach depends on factors such as the location and severity of the clot, the patient’s symptoms, and the risks associated with intervention.

Interventional oncology is another area of rapid development. Image-guided techniques may be used to treat certain liver, kidney, and other tumors. These methods can include microwave ablation, cryoablation, and targeted radiopharmaceutical therapies. They may be used alone or as part of a broader treatment plan developed with oncologists, surgeons, and other specialists.

For Gill, these advances demonstrate why multidisciplinary collaboration matters. Interventional radiology is not a replacement for every surgery or systemic therapy. It is an additional set of options that can be considered when physicians and patients evaluate the safest and most effective path forward.

Why Physician Leadership Requires More Than Clinical Skill

As healthcare technology and delivery systems change, Gill believes physicians must be prepared to lead both inside and outside the procedure room. Clinical judgment remains essential, but modern physician leadership also requires an understanding of teamwork, healthcare operations, financial constraints, regulatory changes, and the factors that influence access to care.

He identifies five qualities that are especially important for physicians:

Empathy. Toward patients, families, and colleagues.

Integrity. In clinical decision-making.

Accountability. For patient care and professional responsibilities.

Adaptability. As medical evidence, technology, and healthcare systems evolve.

Continuous learning. Throughout a physician’s career.

“Modern healthcare demands physicians have a higher ability for leadership,” Gill said. “Physicians should be playing a leading role in healthcare as they are ultimately responsible for

the overall outcome of patient care.”

His view of leadership is grounded in responsibility rather than status. A physician leader must be willing to listen, communicate across specialties, adapt when new evidence emerges, and remain accountable for how decisions affect patients and care teams.

Medical Education, Mentorship, and Academic Contributions

Harkanwar Gill’s interest in medical education extends beyond clinical practice. Over the past year, he has authored two medical book chapters and mentored radiology residents and other medical trainees. He sees teaching as a way to strengthen patient care.

Trainees need technical instruction, but they also learn from how experienced physicians prepare, communicate, collaborate, and respond when a case does not unfold as expected. Gill aims to model careful clinical habits and a patient-centered approach while encouraging young physicians to remain curious about new evidence and technology.

His mentorship also reflects his own experience pursuing a highly competitive medical path.

Training in vascular and interventional radiology requires sustained effort, and international medical graduates may face additional uncertainty as immigration policies and institutional requirements change.

“There were moments I had to step back and reflect on whether this was even possible,” Gill recalled. His advice to physicians facing setbacks is direct: “Trust your abilities, ignore negativity, and stay focused on your goals.”

Perseverance, in his view, does not mean ignoring difficulty. It means assessing setbacks honestly, continuing to develop the necessary skills, and maintaining confidence in a long-term professional goal.

Helping Patients Find Reliable Medical Information Online

Patients increasingly research diagnoses and treatment options before meeting with a physician. Gill welcomes informed questions but recognizes that online medical information varies widely in quality. Technical research papers may be difficult for non-specialists to interpret, while simplified online content may omit important context.

He encourages patients to rely on established medical organizations and to discuss what they read with a qualified healthcare professional. Resources from organizations such as the Society of Interventional Radiology can provide a useful introduction to image-guided procedures, but online education should support, not replace, individualized medical advice.

The Future of Interventional Radiology and Patient Awareness

Gill expects vascular and interventional radiology to continue advancing as imaging becomes more precise and minimally invasive technologies become more sophisticated. He also believes innovation must be paired with education. A treatment option has limited value if patients and referring providers do not know when it may be appropriate.

Professional societies, healthcare organizations, and physicians all have a role in explaining what interventional radiology can and cannot do. That includes communicating evidence clearly, avoiding one-size-fits-all claims, and helping patients understand when a minimally invasive procedure may be considered alongside surgery, medication, or other therapies.

“Vascular interventional radiology is a highly specialized profession practiced by a select group,” Gill said, “and I consider myself fortunate to be among them.” For him, that opportunity carries a responsibility to keep learning, mentor future physicians, and help patients understand the full range of care available to them.
