Understanding Carotid Artery Stenosis: When is Surgery or Stenting Necessary?
I recognize that providing medical counsel isn't possible on platforms like Reddit, but I am eager to learn about the current guidelines regarding carotid artery stenosis. My father has a history of coronary artery disease and has successfully undergone triple bypass surgery. Recently, we were concerned about potential blockages in his carotid arteries, leading us to request a Carotid Doppler and CIMT test. The results revealed that his right common carotid artery (CIA) has 60% calcified plaque stenosis, while the left CIA shows 26% soft plaque stenosis. Additionally, there is noted intima-media thickening at the left bulb measuring 1.8 mm in anteroposterior (AP) dimensions. This finding was quite surprising given that he shows no symptoms at all. He is currently doing remarkably well, having significantly reduced his weight. His triglyceride levels have declined from 340 to 110. He is already on an effective medical regimen which includes Rosuvastatin (40mg), Ezetimibe (10mg), Clopidogrel (75mg), Aspirin (75mg), Bisoprolol (3.75mg), and Lisinopril (2.5mg). Notably, his latest low-density lipoprotein (LDL) level was measured at 35. In a case where a patient is asymptomatic and has 60% stenosis, is any surgical intervention warranted? Is the presence of calcified plaque considered beneficial in this context? In a situation like this, is it advisable to continue purely with medical management? I would greatly appreciate any insights.

Main Points: In cases of carotid artery stenosis, particularly with asymptomatic patients, medical management is often the preferred approach. Surgical intervention like carotid endarterectomy or stenting is typically reserved for specific cases, especially when symptoms are present or stenosis is more severe.
Explanation: Carotid artery stenosis refers to the narrowing of the arteries that supply blood to the brain, often due to plaque buildup. The degree of stenosis and whether a patient is symptomatic are key factors in determining treatment options. According to guidelines from organizations like the American Heart Association and the American Stroke Association, surgical options such as carotid endarterectomy or stenting are generally recommended only for symptomatic patients with 50% or greater stenosis or for asymptomatic patients with 70% or greater stenosis.
In your father’s case, with 60% stenosis on the right common carotid artery and being asymptomatic, current practice leans toward continued medical management rather than surgery. The presence of calcified plaque can be seen as beneficial in some contexts, as calcified plaques are often more stable and less likely to rupture than soft plaques, which may contribute to a stroke.
Next Steps:
- Continue Medical Management: Encourage your father to adhere strictly to his medication regimen, which is already well-established and appears effective in managing his cholesterol and blood pressure.
- Regular Follow-ups: Schedule periodic follow-up appointments for monitoring the progression of stenosis and overall vascular health, including assessments of his cardiovascular risk factors.
- Lifestyle Modifications: Support him in maintaining a heart-healthy lifestyle, emphasizing a balanced diet, regular exercise, and weight management, as these significantly impact cardiovascular health.
- Education & Awareness: Keep informed about symptoms of potential cerebrovascular events (like sudden weakness, difficulty speaking, or vision changes) so that you can act quickly if needed.
By focusing on these steps, you're supporting his health and ensuring that he remains well-managed in terms of his risk for stroke despite the observed stenosis. Let me know if you have specific questions related to his current management or health goals!

Questions Surrounding Cause of Death
My father, aged 80, recently succumbed to AML leukemia after a five-month struggle. Although we were aware he was unwell, we were caught off guard by his passing since his cancer had entered remission. Unfortunately, he never returned home for outpatient therapy; the inpatient chemotherapy proved to be detrimental to his health. This treatment led to frequent issues with fluid retention in his body, resulting in low blood pressure and hindering his physical therapy progress. He also experienced two episodes in the ICU due to sepsis and alarmingly low blood pressure, with no infection source found during the second incident. Despite efforts to drain excess fluid from his chest and abdomen, it continued to accumulate, prompting concern from his doctors regarding potential liver complications. The communication surrounding his condition was incredibly unclear. One day, they reported that a CT scan indicated his liver was “lumpy and bumpy,” suspecting cirrhosis and liver failure, which was shocking information given he hardly drank alcohol. However, the following day, additional assessments suggested that his liver appeared to function adequately. The focus then shifted to his kidneys, with concerns about his minimal urine output suggesting he might require dialysis. Fortunately, after being administered medication that increased his urine production, they concluded that dialysis was unnecessary. He was released from the ICU, albeit still feeling quite unwell. The next day, we had discussions regarding hospice care, and within hours, I received a call indicating he was “actively dying,” with his oxygen levels plummeting. He passed away just 15 minutes later. This sequence of events left me bewildered and traumatized. How could someone in remission, well enough to leave the ICU, deteriorate and die so swiftly? The death certificate cited hypoxic respiratory failure stemming from renal and liver failure, with heart failure and septic shock listed as contributing conditions. I am puzzled as to why there was no mention of heart failure during his treatment, and if someone doesn’t require dialysis, can they still be classified as experiencing kidney failure? If the liver tests appeared normal, how could liver failure still be a diagnosis? I can’t shake the worry that my father may have suffered distress during his final moments, although the nursing staff assured me his passing was “peaceful.” In such a rapid decline, could they have administered comfort medication to ease his transition? I regret not having the opportunity to speak with a doctor about my father’s situation. I received only a single phone call from a physician who seemed distracted and struggled to answer my questions. At that moment, it felt futile to pursue further information, especially since he had already passed, but now I yearn for clarity and understanding. Any guidance you could provide would be immensely appreciated. Thank you.
Forearm Injury from Cat Scratch: An Unusual Blood Accumulation
This incident occurred about a week ago, and thankfully, I'm not in any immediate risk. I’m a 40-year-old male and the only medication I think might apply to my situation is a beta blocker. About a week back, while tending to a stray cat, I ended up with a scratch that led to an eerie, blood-filled bulge on my forearm that reminded me of a scene from John Carpenter's "The Thing." Rather than just a minor scratch, a small puncture from one of the cat's claws resulted in a peculiar, blood-filled protrusion that jutted out at a right angle from my arm. It resembled a diminutive pinky finger sticking out from the side of my forearm. In a panic, I doused the area with hydrogen peroxide; shortly thereafter, the bulge began to shrink, leaving the skin in that section feeling loose for a little while. The following day, I noticed that a significant portion—about three-quarters—of my forearm was heavily bruised, exhibiting a dark purple hue. Remarkably, this discoloration has faded quite rapidly; usually, such a severe bruise would take much longer to heal. I’ve kept an eye out for any symptoms of cat scratch fever, and everything appears to be normal. What I’m really curious about is whether it’s actually possible for skin to erupt like a blood-filled balloon from a vein so quickly. I witnessed it firsthand, and I just need reassurance that I’m not imagining things.
Unexpected Resolution of Shoulder Pain Over Time
Good evening, everyone. For several months, I've been grappling with persistent pain and stiffness in my shoulder, which radiated into my bicep. In an effort to alleviate this discomfort, I opted for shockwave therapy, a treatment that had previously provided relief, though this time it didn’t yield any improvement. After undergoing an x-ray, my physiotherapist informed me that there were indications of mild osteoarthritis and bone spurs. However, my doctor suspects that I may have a rotator cuff tear or tendonitis and has recommended an MRI for further investigation. Despite these challenges, I've continued my gym routine but have been very cautious about the arm exercises I perform. Recently, I attempted some light lat pull-downs; initially, everything felt fine as I pulled the bar down, yet I was taken by surprise when I experienced a sudden, sharp pain shooting from my shoulder down to my elbow upon releasing it. I promptly ceased the exercise. Later that evening, my shoulder grew increasingly sore, making it difficult to raise my arm to waist height without significant pain. However, within 48 hours, I noticed an unexpected change — the persistent pain in my shoulder that had troubled me for months seemed to have mostly vanished in the last few days. I’m left wondering if anyone can offer insight into this abrupt change or what might have transpired. While I plan to proceed with the MRI as a precaution in case the pain resurfaces, I find myself puzzled about the potential underlying issues. 🤔
Inquiry About Nerve Injury Recovery
Greetings, in late August 2025, I experienced a significant incident where I was severely bitten by a German shepherd on my left forearm when I was 22 years old. During the attack, the dog shook its head, which contributed to the severity before my father managed to intervene. After a couple of hours, I visited urgent care, despite my father's initial hesitation to seek treatment. There, I was prescribed antibiotics and given guidelines on how to clean the wound and manage my recovery. The medical professionals I consulted indicated that the extent of my injuries would likely mean a prolonged recovery, noting that my forearm had swelled considerably and formed a large hematoma due to the trauma. Currently, I am worried about ongoing weakness and rapid fatigue when using my affected muscles, which are in my dominant arm, as well as persistent burning sensations and numbness in the area. While the discomfort has become less intolerable, it's still not pleasant. I find myself uncertain about the healing timeline for such injuries beyond the initial expectations set during those early weeks. Is it typical to experience this degree of ongoing pain with an injury of this nature? Additionally, I am on various psychiatric medications, including antidepressants, mood stabilizers, and antipsychotics, and have recently started gabapentin for a previous back injury, which has shown some efficacy. I also have Ehlers-Danlos Syndrome, which I suspect might be influencing my recovery process.
Seeking Advice for Upcoming Doctor's Visit
Greetings. I am a 48-year-old male, weighing 100 kg and standing at 176 cm tall, residing in Sweden. I am currently on medication for high blood pressure and cholesterol. As I lay in bed at home, I'm anticipating the morning to come. To provide some background, I began experiencing mild discomfort in my abdomen approximately 24 hours ago while returning from a vacation. At the airport, I used the restroom, where I had a slightly loose stool, which momentarily alleviated my discomfort. However, during the six-hour flight, the pain in my stomach persisted, albeit at a lower intensity. Upon returning home, I went to the bathroom again, and the stool was somewhat soft this time. Unfortunately, the abdominal pain didn’t subside; it actually intensified. Consequently, I sought assistance at the local emergency department, where I was assessed and subsequently referred to a nearby clinic for further evaluation. I spent around two hours waiting before being examined by a physician (I even had an episode of vomiting). The doctor examined my abdomen and performed a blood test. After a brief wait of about 20 minutes, he returned with a diagnosis suggesting it was likely a bowel infection (not appendicitis). He advised me to rest at home, take paracetamol, and visit my local clinic in the morning if the pain persists. Now, as I prepare for my appointment tomorrow, the pain has subsided slightly; I would rate it about 7 out of 10. I feel utterly drained from the sleepless night and ongoing discomfort. What steps should I take during my consultation with the doctor?
