The UT Health’s Vascular & Interventional Radiology section provides minimally invasive procedure services for San Antonio’s University Hospital and UT Medicine Systems; including imaging centers at University Hospital and Robert B. Green Clinic. Our section is composed of 4 board-certified radiologists who have achieved additional subspecialized training through ACGME certified Vascular & Interventional Radiology fellowships. The section provides a wide range of minimally invasive procedures that can be performed as ambulatory outpatient visits or require just short observation admission periods, typically less than 24 hours. Some of the minimally invasive percutaneous procedures offered include:
- Uterine Fibroid Embolization (UFE): a minimally invasive procedure highly effective in the treatment of symptoms from uterine fibroids.
- Prostate Artery Embolization (PAE): a cutting edge ambulatory procedure to treat the urinary symptoms from Benign Prostatic Hypertrophy.
- Vertebroplasty/Kyphoplasty: Fractures of the spine are very common in patients with osteoporosis, the loss of bone mass makes the vertebra susceptible to fractures with minimal or no trauma.
- Endovascular treatments for Peripheral Vascular Diseases (PVD): minimally invasive interventions that improve symptoms from arterial or venous circulation diseases.
- Percutaneous treatments of symptomatic cysts and vascular malformations (AVM’s).
- Tumor loco-regional treatments (ablation, chemoembolization, Y-90 radioembolization, etc): a wide variety of minimally invasive treatments options for a wide range of benign tumors and cancers (including liver, lung, kidney and localized metastasis from colorectal, breast and others)
- Biopsies: percutaneous image-guided ambulatory procedures for diagnosis and staging of a variety of diseases.
- Drainages and stents: wide range of minimally invasive interventions aimed to relief obstructive diseases or drain abnormally retained fluid collections like abscesses or visceral leaks.
- Gastrostomy tubes and other enteral support drains ambulatory procedures to aid in the management and relief symptoms from swallowing or visceral transit problems.
- Nephrostomy drains and urinary stents: minimally invasive procedures to treat urinary obstructive diseases or leaks.
- Advanced vascular access: ambulatory interventions to provide adequate vascular access requirements for the medical management of multiple diseases including subcutaneous Port-catheter placements, a variety of tunneled subcutaneous vascular accesses and PICC lines.
- Hemodialysis access maintenance: minimally invasive ambulatory evaluation and treatment of failing hemodialysis fistulas and grafts to prolong their functionality.
- Peritoneal Dialysis (PD) catheter placement: minimally invasive placement of Peritoneal Dialysis drains.
- Hepatobiliary and Portal hypertension percutaneous interventions: a wide range of minimally invasive procedures that diagnose and improve symptoms that result from liver disease.

Dr. Kroma received his M.D. degree from Damascus University in Syria in 1994. He completed his residency in Diagnostic Radiology in 1997 at Damascus University. Dr. Kroma worked as a diagnostic radiologist in Syria and Saudi Arabia from 1997 to 2004. He then completed a Neuroradiology fellowship at Louisiana State University in 2005; followed by two years of Interventional Radiology fellowships at Louisiana State University and the University of Texas Health Science Center at San Antonio. He joined UT Health’s faculty in 2007. Dr. Kroma is certified by the American Board of Radiology for diagnostic radiology followed by a Certificate of Advanced Qualification in vascular interventional radiology (CAQ). His expertise include: Local treatment of liver cancers by radioembolization, chemoembolization and thermal ablation, local treatment of renal cancer by intra-arterial embolization and radiofrequency ablation, Uterine fibroid embolization, kyphoplasty and vertebroplasty , endovascular treatment of peripheral arterial disease, transjugular intrahepatic portosystemic shunts and balloon-assisted obliteration of gastric varices, management of post-liver and kidney transplantation complications, dialysis access maintenance, in addition to multiple percutaneous and endovascular procedures. Dr. Kroma is the program director for the Interventional Radiology residencies.

Dr. Suri received his M.D. degree from The Christian Medical College in India. He has completed residencies in diagnostic radiology at Cedars Sinai Medical Center in Los Angeles and at the Postgraduate Institute of Medical Education and Research in India. He completed a Cardiovascular and Abdominal Interventional Radiology Fellowship at the University of California Los Angeles. Dr. Suri is Board Certified by the American College of Radiology. His clinical interests include: carotid artery stent placement, chemoembolization, infrainguinal arterial interventions, radiofrequency ablations, uterine fibroid embolizations, and transjugular intrahepatic portosystemic shunts.
Associate Program Director, Diagnostic Radiology
Dr. John A. Walker, a native to Texas, completed his medical training with the UT Health San Antonio Long School of Medicine. He then obtained a research doctorate in imaging here in the UT School of Biomedical Sciences while simultaneously training in our Diagnostic Radiology residency, leading to the completion of the prestigious ABR Holman Radiology Research Pathway. He then completed a fellowship in our Vascular and Interventional Radiology Program. Upon completion of his training, Dr. Walker joined our UT faculty in 2016. He remains interested in regenerative medicine and perfusion imaging research. He performs a wide range of minimally invasive procedures with extensive training in liver interventions that include loco-regional cancer treatments, portosystemic shunt creation and management, bile duct disease and post-transplant management. He has experience treating uterine fibroids, female pain related to pelvic congestion, similarly male varicoceles, and is trained in a multitude of venous and arterial interventions to include dialysis access issues.
