Conveniently serving patients across Houston and surrounding communities with expert specialist care close to home.
Dr. Sharma is a board-certified interventional radiologist serving patients throughout the Greater Houston area. Specializing in minimally invasive, image-guided procedures, he provides targeted treatments for vascular disease, women's health, prostate conditions, knee pain, and dialysis access — helping patients avoid major surgery and return to life faster.
About Dr. Sharma
Dr. Sharma leads interventional radiology services at Helios Vascular, bringing advanced image-guided techniques to patients who want effective, minimally invasive treatment without the burden of open surgery.
His practice spans the full spectrum of interventional radiology — from treating uterine fibroids and enlarged prostates, to restoring blood flow in blocked arteries and managing dialysis access for kidney disease patients.
PAD angioplasty & stenting to restore circulation in blocked or narrowed peripheral arteries.
Laser and radiofrequency ablation for varicose veins and chronic venous disease.
Targeted blockage of blood supply to fibroids, prostate, knee vessels, and more.
IR Procedures
Each procedure is performed outpatient using advanced imaging guidance — targeting disease precisely with minimal disruption to surrounding tissue and dramatically faster recovery than open surgery.
Non-surgical treatment for chronic knee pain from osteoarthritis. Tiny particles delivered via catheter reduce abnormal blood vessels in the knee joint lining — relieving pain without surgery or joint replacement.
A proven alternative to hysterectomy. UFE blocks blood supply to uterine fibroids, causing them to shrink and relieving heavy bleeding, pelvic pressure, and pain — with the uterus preserved.
Balloon angioplasty and stenting restore blood flow to narrowed or blocked leg arteries. Relieves claudication and rest pain, prevents wounds, and reduces amputation risk.
Minimally invasive treatment for BPH (enlarged prostate). PAE reduces urinary symptoms by decreasing prostate blood flow — avoiding the risks of traditional surgical procedures.
Endovenous laser ablation (EVLA) and radiofrequency ablation (RFA) seal diseased veins from within — eliminating varicose veins and chronic venous symptoms with minimal downtime.
Comprehensive management of hemodialysis access including fistula and graft declotting, angioplasty of stenoses, and catheter placement for reliable long-term dialysis access.
Image-guided balloon angioplasty opens narrowed or blocked peripheral arteries. Stent placement maintains vessel patency for limb-threatening ischemia and circulation restoration.
Minimally invasive treatment for swollen scrotal veins causing pain or affecting fertility. Embolization closes the abnormal veins without surgery or general anesthesia.
Uterine artery embolization to shrink fibroids causing heavy periods, pelvic pressure, or pain. Performed outpatient — most patients resume normal activities within one to two weeks.
Why Choose IR
Interventional radiology uses advanced imaging to deliver treatments through tiny incisions — transforming what once required open surgery into an outpatient procedure.
Procedures performed through a pinhole incision using catheters guided by real-time X-ray and ultrasound imaging — no large surgical cuts required.
Most procedures are outpatient. Patients frequently return to normal activity within days rather than the weeks required after open surgery.
Lower risk of infection, scarring, and anesthesia-related complications compared to traditional surgical approaches.
Real-time imaging allows Dr. Sharma to treat the exact site of disease with millimeter accuracy, preserving surrounding healthy tissue.
