ABSTRACT
Interventional radiology is an emerging field in Nigeria, with well-established practices in the Global South, including the United
Kingdom and the United States. This article aims to highlight significant advancements, including the establishment of professional
organizations and training programs. It provides a historical context, examines the current state of interventional radiology practice,
and addresses challenges that impede the widespread adoption of IR in Nigeria.
Additionally, it identifies the critical factors driving progress in this field and presents solutions to tackle existing barriers effectively.
It also offers strong insights into the future trajectory of IR in Nigeria, ensuring enhanced access to minimally invasive, image-guided
procedures for the Nigerian population.

INTRODUCTION
Interventional radiology (IR) is a rapidly advancing and highly
innovative medical specialty
(1)
. It originated on January 16,
1964, when Dotter performed a percutaneous dilation
procedure on an 82-year-old woman suffering from painful leg
ischemia and gangrene. The patient had a tight, localized
stenosis of the superficial femoral artery (SFA) and refused leg
amputation. Dotter successfully dilated the stenosis with a
guide wire and coaxial Teflon catheters, restoring circulation to
her leg
(2)
. This field uses image-guided techniques for minimally
invasive procedures, offering lower-risk alternatives to many
traditional medical and surgical therapies
(3)
, utilizes advanced
imaging techniques such as ultrasound, X-rays, Computed
Tomography (CT) scans, Magnetic Resonance Imaging (MRI)
scans, and other innovative methods
(4)
.
An interventional radiologist is a highly skilled physician who
performs image-guided procedures and interprets the imaging
necessary to guide and monitor a patient’s response to those
procedures. They also provide comprehensive pre- and post-
procedural care for patients
(1)
. These specialists are at the
forefront of clinical advances and use the latest image-guided
technologies. They are trained in radiology and minimally
invasive procedures and work across the body to administer
minimally invasive treatments for various conditions
(4)
.
Furthermore, interventional radiologists can diagnose and treat
diseases by inserting small devices, such as catheters or wires,
into the body
(5)
. They use X-ray and imaging methods such as
CT and ultrasound to guide them in visualizing inside the body
and treating complex conditions, including cardiovascular
disease and cancer, with less invasiveness and unprecedented
precision
(4)
.
Most procedures are carried out through incisions less than
5mm. It is often possible to avoid general anesthetics. The
majority of the procedures are performed under local anesthesia,
sometimes combined with sedation. This makes patients
recover faster, usually requiring less time off work and is cost-
effective. Patients typically experience quicker healing, and
minimal scarring, and can undergo complex procedures
without prolonged hospital stays. Additionally, they can
resume their normal lives more rapidly
(1)
. There is also reduced
blood loss and apprehension

This paper investigates the current status, factors that drive
change, future directions, and challenges facing interventional
radiology in Nigeria.
