An aortic aneurysm is a dilatation of the aorta which predisposes itself to rupture, hemorrhage and death in short order. The aorta is the largest vessel in the body carrying blood out to the rest of the other organs. There are three layers in the aorta—intima, media and adventitia. A true aneurysm is a dilatation of all three of these layers. When an aortic aneurysm ruptures, there is only a short time frame to emergency surgery to repair it before death ensues.
Aortic aneurysms are usually silent killers in that most (almost all that involve the abdominal part of the aorta and half that involve the upper or thoracic part) are generally asymptomatic. A physical exam may detect a pulsatile mass in the abdomen that corresponds to an aneurysm that hasn’t yet ruptured, but the majority of aneurysms are discovered on more routine imaging. Chest X-rays or ultrasounds are the most common detection methods. Symptoms of a large aneurysm may include low back or mid-abdominal pain or trouble swallowing when the aneurysm compresses the esophagus. Once the aneurysm ruptures, chest pain is sudden and severe along with a sharp drop in blood pressure and throwing up or coughing up blood. Death is common when there is not proximity to a hospital or operating room, and even surgical morality in an acute situation may be as high as 50 percent.
Risk factors for aortic aneurysms are many. Men over age 65, hypertension, smoking and high cholesterol are a few of the major ones. Others include weight lifting, trauma, a bicuspid aortic valve or any other kind of aortic valve disease. Genetic causes including Marfan’s syndrome (a particular offender), Ehlers-Danlos syndrome and Turner’s syndrome are widely recognized. Inflammatory diseases such as ankylosing spondylitis, giant cell arteritis and Takayasu arteritis cause weakness in the aorta through their underlying inflammatory component and screening for an aneurysm may be part of the disease for these conditions work-up per se.
How to treat an aneurysm when discovered in an asymptomatic person has undergone changes in recent years, but is still designed to get to the aneurysm and surgically repair it before it is too late. That said, not every discovered aneurysm is referred immediately for surgery. Things that go into when to make the repair are time since discovery, size of the aneurysm, underlying conditions (like atherosclerosis, hypertension and smoking) and the rate of growth of the lesion. Clinical problems are rare when the aneurysm is 4 cm in size or less. Between 4 and 5 cm, the mortality rate increases but again surgery is not an immediate consequence. Once the aneurysm measures 5.5 cm (this is an increase from the previously accepted 5.0 cm) or the growth is marked in between radiographic evaluations, surgery to accomplish repair is undertaken. As mentioned, this is not an operation with trivial surgical risk, so repair is accomplished in those with larger lesions. The annual rate of rupture is highest in the larger lesions and a rupture may be fatal in up to 80 percent of these cases.
Surgery is usually accomplished as an open repair of the aorta. It must be done in skilled hands as the aorta then certainly is a weakened vessel subject to further problems if not done effectively. As it is a problem in older individuals, a procedure called EVAR (endovascular aortic aneurysm repair) is done in older individuals who are considered high operative risks due to the presence of other complicating diseases or circumstances. It requires indefinite surveillance to monitor for leaks, closing of the vessel or re-expansion even though it is safer for high risk individuals.
Underwriters who assess aortic aneurysm look for various factors in assessing its future morbidity and mortality. The location of the aneurysm is important, as well as the size, cause, treatment, and rate of growth if unoperated. Monitoring control of other contributing conditions is important as well, both in the operated and unoperated individuals. Follow-up is also key— those who do not have adequate medical follow-up with this condition increase their mortality several fold.
Smaller aneurysms may be taken with a small rating as long as follow-up is good. Larger ones have to be followed with care to assess stability, as their rate of growth may pre-dispose them to acute injury and death if a rupture occurs and an operating room is not immediately in reach. There may be a waiting period of six months to a year before insurance is considered after surgery, and the longer time goes by without a recurrence the better. Those with EVAR as treatment are rated more severely as the procedure for repair is not as complication free and there are generally other health problems that were significant enough to have chosen that approach over the more tested open repair.
COVID: The Difficulty Of Underwriting The “Long Haulers”
As I write this, my home state of California has reported over 2.3 million cases of COVID-19, and recorded over 26,000 deaths. The United States has already seen over 20 million recorded COVID cases, and the death toll stands at over 350,000. These are only “so far” numbers, and the slow vaccine roll out to date ensures we are nowhere near the final count on these statistics. And these numbers are only the cases we know about, not the equally massive number of cases where there was a recovery without a laboratory diagnosis or deaths where COVID may have been a major unreported factor—particularly in the elderly.
Thankfully, the number of COVID affected individuals has resulted in a large amount of recovered cases. Or what we assume are recovered cases. Many have gone back to their lives and situations with residual symptoms, even if mild. A small but significant amount who have “recovered” from the acute phase of the illness still have a degree of disability which affects their day-to-day living. These are the “long haulers”—those in whom COVID has spared in the short term but in whom we have truly no idea of what the long term prognosis will be, either morbidity or mortality wise.
Disease-impacted underwriting depends on estimating life expectancy (for life insurance), degree and duration of disability, and long term costs of care for health, disability and long term care. Much of this is based on experience of watching the course of illnesses in multitudes of people and understanding both the process and course of the disease. COVID however is a horse of a different color—we have no experience in how this has played out at other times and only guesstimates of how it will work in the future. Cases followed in the United States have barely reached the one-year point. It has become obvious, even in that short time, that recovery is not always complete, and that remaining objective signs and symptoms have potential to cause continued decompensation in the long run.
Cases of regular exposure where a COVID test is positive and there are minimal symptoms and a return to work without problems are still standard to preferred cases as they were before the infection. Those who were admitted to the hospital but required no ICU care or intubation and had a recovered course likewise don’t appear to date to have recurrent symptoms or compromise. Where it gets more difficult are three categories where more intensive treatment was necessary. Those include admission to the hospital with symptoms and the need for more than routine treatment (remdesivir, oxygen support, etc.), those who were hospitalized for a significant amount of days and whose course required an ICU admission (even not intubated), and those with an ICU admission where other medical problems surfaced with a prolonged hospital stay and where rehabilitation was needed.
Underwriting these cases requires much more care toward these latter classes. Besides perhaps a postpone period to see how symptoms persist or progress, additive testing may be required. Repeat chest X-rays and even chest CTs may be required. Laboratories in follow-up visits must be reported. Face-to-face follow-up care may be required above and beyond tele-visits. Exercise echocardiograms may be particularly helpful in assessing any long lasting cardiac compromise or continued decompensation. And even psychometric testing to screen for PTSD, continued severe anxiety and depression and failure to cope post infection may also be important to assess.
Maybe most perplexing are the long haulers still affected after what seem to be mild or moderate symptoms from the initial infection. Many patients haven’t fully recovered their normal activity level, and remain incapacitated or house bound. Coronavirus may leave patients with a condition called POTS (postural orthostatic tachycardia syndrome), where heart rates can double or triple on standing, blood pressure can drop precipitously, and just about all conditions that are dependent on normal regulation of blood pressure and pulse go out of whack. Dizziness, headaches, shortness of breath, chest pain and “brain fog” (where periods of time without clear thinking occur) cause short term problems and may worsen other body functions. The long effects of this on the heart, the autonomic nervous system, and pulmonary and brain functions are truly unknown. What is the course of COVID induced POTS? We truly don’t know with this limited time experience.
Underwriting is going to be a lot tougher and with a lot more caution in COVID cases and certainly in long haulers where the infection continues to cause symptoms and impairments well into months after infection. Careful examination of medical records and longer periods waiting for in-person visits may be necessary. Testing, whether as routine as for blood, or with scanning and testing cardiac and lung function, may be required. Return to work for a defined period of time without decompensation may need to be demonstrated. And in long haulers, an indefinite period of postponement may be required until we are best able to evaluate the long term effects of this pandemic virus which has caused so much disruption and harm in our lives as a people.
