by [Dr. Scott Sundick, MD, FACS](https://health.veininstitutenj.com/blog/author/scott-sundick-md-facs) - [April 2nd, 2026](https://health.veininstitutenj.com/blog/watchful-waiting-understanding-care-for-small-aortic-aneurysms) - - Share on Hearing the words *“you have an aneurysm”* can be frightening. Many patients immediately assume that something dangerous is happening inside their body and that surgery must be needed right away. When a physician then recommends **monitoring the aneurysm rather than treating it immediately**, patients often wonder if something is being missed or delayed. In reality, **careful monitoring, often called “watchful waiting” or surveillance, is the safest and most appropriate approach for many small abdominal aortic aneurysms (AAA).** Understanding why physicians take this approach can help patients feel more confident and informed about their care. ## First, What Is an Aortic Aneurysm? The **aorta** is the largest artery in the body. It carries oxygen-rich blood from the heart to the rest of the body. An [**abdominal aortic aneurysm (AAA)**](https://health.veininstitutenj.com/blog/can-i-prevent-getting-an-abdominal-aortic-aneurysm-aaa) occurs when a section of the aorta in the abdomen becomes weakened and begins to bulge outward, similar to a balloon expanding in a weak area of a tire. Many aneurysms develop slowly over time and may not cause symptoms. They are often discovered during imaging tests performed for other reasons or during vascular screening exams. ## Why Not Treat It Immediately? The key factor in deciding how to manage an aneurysm is **risk**, specifically the risk of the aneurysm rupturing versus the risks involved with treatment. For **smaller aneurysms**, the likelihood of rupture is typically **very low**, while the risks associated with surgery or endovascular procedures may be higher than the risk posed by the aneurysm itself. Due to this, vascular surgeons often recommend **regular monitoring instead of immediate intervention**. This approach allows physicians to track the aneurysm and intervene **only if it becomes necessary**, avoiding unnecessary procedures. ## The Most Important Factor: Size The **diameter of the aneurysm** is the most important predictor of rupture risk. In general terms: These thresholds are based on decades of research showing that **larger aneurysms carry a significantly higher risk of rupture**. However, size alone does not determine treatment decisions. ## Growth Rate Matters Too Another important factor is **how quickly the aneurysm is growing**. Most small aneurysms enlarge slowly, sometimes **only a few millimeters per year**. When an aneurysm grows more rapidly often defined as: physicians may recommend treatment sooner. Regular imaging helps detect these changes early. ## The Role of Imaging and Surveillance Patients with small aneurysms are typically monitored using **noninvasive imaging**, most commonly: The timing of these studies depends on aneurysm size but may occur **every 6–12 months**. These imaging tests allow vascular surgeons to track: Surveillance ensures that **if intervention becomes necessary, it can be planned at the right time.** ## Other Factors Doctors Consider Every patient is different, and physicians evaluate several additional factors when determining the safest plan. These include: Body size and anatomy Aneurysm size may be interpreted differently depending on a patient’s body habitus and aortic anatomy. Age and overall health Patients with other medical conditions may have different risk profiles. Smoking history Smoking is one of the strongest risk factors for aneurysm growth and rupture. Family history Some aneurysms have genetic associations. Other cardiovascular conditions Conditions such as peripheral artery disease, coronary artery disease, or high blood pressure can influence overall risk. **Treatment decisions are highly individualized** because of these variables. ## When Treatment Becomes Necessary If an aneurysm reaches a size where rupture risk increases, treatment may be recommended. There are two primary approaches: Endovascular aneurysm repair (EVAR) An [EVAR](https://health.veininstitutenj.com/blog/what-is-an-endovascular-aneurysm-repair-evar) is a minimally invasive procedure in which a stent graft is placed inside the aneurysm through small incisions in the groin. Open surgical repair A traditional operation in which the weakened section of the aorta is replaced with a surgical graft. The best option depends on the patient’s anatomy, overall health, and the characteristics of the aneurysm. ## What Patients Can Do During Watchful Waiting Although surveillance does not involve immediate surgery, it is **not passive care**. Patients can take several steps to reduce risk and slow aneurysm growth. Important measures include: These steps help support vascular health and reduce complications. ## Reassurance Through Monitoring It is natural to feel anxious after learning you have an aneurysm. However, the decision to monitor rather than treat immediately is based on careful scientific evidence and years of clinical experience. In many cases, **watchful waiting is the safest and most appropriate strategy**. Regular monitoring allows physicians to track the aneurysm closely while avoiding unnecessary procedures. If treatment ever becomes necessary, it can be performed at the right time and when the benefits clearly outweigh the risks. ## When to Speak with a Vascular Surgeon If you have been diagnosed with an abdominal aortic aneurysm, or have risk factors such as **smoking history, family history of aneurysm, or cardiovascular disease**, a vascular evaluation can provide clarity and peace of mind. At the Vein Institute of N J at **The Cardiovascular Care Group**, our vascular surgeons use advanced imaging and individualized risk assessment to determine the safest and most effective management strategy for each patient. Whether that means **ongoing surveillance or intervention**, our goal is always the same: protecting your vascular health through informed, personalized care.
