Background

Our blood travels through our bodies constantly. It travels through a network of arteries and veins to deliver oxygen and nutrients to keep every organ in our body alive. However, when those vessels become blocked, weakened, or damaged, the consequences can be terrifying and life-threatening. From possible strokes and aneurysms to limb loss, it can be one of the scariest moments of our lives. But there are specialists who work to repair and rebuild these important pathways. Those individuals are known as vascular surgeons. Vascular surgery is a specialty that is dedicated to diagnosing and treating diseases of the circulatory system outside of the heart and brain. 

So, what do they do?

Vascular surgeons focus on restoring circulation in their patients whose blood vessels may be damaged by disease, injury, or defects. They also look at whether the pathways have been blocked for similar reasons and are restricting blood flow to organs.


Some of the common cases that they deal with include:

  • Peripheral artery disease (PAD), which restricts the blood flow to the limbs

  • Aortic aneurysms, or weakened sections of the body’s main artery

  • Carotid artery disease, a major cause of stroke

  • Deep vein thrombosis (DVT) and varicose veins

  • Vascular trauma or limb ischemia (due to insufficient blood supply)


Unlike some surgical specialists who focus only on the patients they are operating on, vascular surgeons deal with their patients through a long process in order to ensure success with their long-term health. They monitor chronic conditions, prescribe medications, and work closely with cardiologists and internists to control risk factors such as high blood pressure, diabetes, and even cholesterol.

Additional Information

Previously, many procedures performed by vascular surgeons required large surgeries. However, with new imaging technology, vascular surgeons have begun relying on minimally invasive techniques.


Some tools that vascular surgeons may use in the modern day include

  • Endovascular stents in order to reinforce weakened arteries from within their patient’s body

  • Catheter-based procedures in order to remove clots or repair aneurysms through small punctures instead of open cuts

  • Ultrasound and fluoroscopy for real-time imaging for delicate interventions

  • Hybrid operating rooms where surgeons switch between open and endovascular approaches.

Required education and training

After earning their bachelor’s degree and completing four years of medical school, students are able to enter either a five-year integrated vascular surgery residency or complete a general surgery residency that is followed by a two-year vascular fellowship.


During their training, residents gain experience in open and endovascular procedures, where they learn how to operate on the entire circulatory system, from tiny leg arteries to the aorta in the chest. Many may also train in vascular imaging and wound care for more complex cases.


Some surgeons may choose to pursue fellowships in order to develop subspecialties such as 

  • Aortic surgery

  • Endovascular innovation and device development

  • Limb salvage and wound management

  • Vascular trauma or critical care

Importance

The circulatory system is one of the most important parts of the body, if not the most important. When it fails, every organ and tissue in the body suffers. Vascular surgeons don’t only open up these arteries, but they save the lives of each and every individual by making sure that oxygen and blood can flow where it needs to.

Background When most people think about surgery, they usually think about surgeons standing over their bodies and performing various procedures in order to save someone. Now although that is true, there’s a hidden figure behind every successful surgery that most people tend to overlook: the anesthesiologist. Anesthesiologists are responsible for managing pain levels, monitoring patients' vital signs, and making sure that their patients not only remain safe, but also stable throughout their surgery. Without these professionals, mortality rates would increase and the surgical process that we have today wouldn’t exist at all. So, what do they do? Anesthesiologists are docto...

Background One of the most demanding and precision requiring medical specialties is neurosurgery. Neurosurgeons are doctors who operate on the brain, spinal cord, and the nervous system. They perform some of the most complex and precise procedures in all of the medical field. Whether they are removing brain tumors, repairing spinal injuries, or stopping seizures, neurosurgeons are one of the most important types of doctors. As neurosurgery isn’t just simply cutting and stitching within the body, it is about navigating and working with the body's most important and delicate system: the nervous system. The system controls an individual's every thought, movement, and he...

Urology: Treating The Overlooked System of the Body

Background Every time we drink a glass of water or some other liquid, our bodies rely on a complex system of organs in order to filter out waste, produce urine, and maintain our internal balance. However, when this system fails, it requires a special type of doctor in order to restore it. That doctor is a urologist. Urology is the branch of medicine that focuses on the urinary tract in both men and women, and the male reproductive system. It is a specialty that combines surgery and internal medicine. This allows urologists to treat a wide range of conditions from kidney stones and bladder infections to prostate cancer. So, what do they do? Urologists are physicians who are tr...
