Aneurysms: Why the CT Angiogram Matters More Than the Radiology Report
May 10, 2026
Whether abdominal, thoracic, femoral or below, the referral principle for an aneurysm is identical to arterial disease: get a CT angiogram. Dr. Purkayastha is blunt that a report reading “infrarenal abdominal aortic aneurysm” or “suprarenal abdominal aortic aneurysm” tells him very little; the image tells him the landing zones, the maximal diameters and the preferred modality of intervention. Fancy, unsupported recommendations (TAVI for a dilated aortic root, TEVAR without seeing the anatomy) are not useful from a referring source; a basic recommendation is fine, but old-fashioned open repair remains the right choice in many cases even today.
The cost gap between the two approaches is significant and worth knowing before a family commits to travel: an open abdominal aortic aneurysm repair runs approximately USD 10,000 to 15,000, while an endovascular stent graft repair runs approximately USD 45,000 to 50,000, largely because the stent graft itself costs around USD 30,000. The choice between them is the vascular surgeon's decision, based squarely on what the image shows, not on a report-based or AI-generated suggestion.
This guide is based on a live Jivo Masterclass — Dr. Biswarup Purkayastha taught doctors across Africa on May 10, 2026.
FROM THE LIVE Q&A
Dr. Ivan, Uganda
Can a patient with DVT have a normal D-dimer?
Dr. Biswarup Purkayastha
Absolutely, yes — particularly if the D-dimer is done after the acute phase, in a subacute presentation of a few days. Despite the test's high sensitivity, the result can come back in the low hundreds, nowhere near diagnostic. DVT is an anatomical problem, and for an anatomical problem the answer is to see it directly on ultrasound, not infer it from a blood marker. Vascular ultrasound is learnable within three to four months, and we train nearly all our trainees to do it routinely.

Frequently Asked Questions
What are the key prognostic factors for endovascular laser ablation of varicose veins?▼
Laser ablation for superficial spider veins or one or two perforators has an excellent prognosis, and works well up to the perforator level. But if the saphenofemoral junction itself is regurgitant, open surgery to ligate the SFJ and clip the draining tributaries is usually the better option rather than relying on endovascular ablation alone.
A 78-year-old patient has arterial disease in the below-knee territory. Some doctors suggested angioplasty, while top vascular surgeons felt nothing needed to be done and that intervention carried risk. What is your view?▼
In a fragile patient, angioplasty is best avoided below the knee — it gives reasonable short-term results but nothing very promising long-term. If intervention is genuinely needed, it is more often approached surgically, favouring a reverse femoro-tibial bypass using the patient's own saphenous vein over a prosthetic graft, and favouring open surgery over an endovascular approach in this territory. Below the knee: use the simpler, older, better-proven option, and know when not to intervene at all.
You mentioned a case where a patient initially appeared to have an arterial pain problem but ultimately did not need a vascular intervention. Can you say more?▼
It is a vascular disease, but the vascular problem is not what is causing the pain in this elderly lady — and if medicines can manage the condition, there is no need to intervene, even if that is commercially a loss rather than a win. There has been a silent shift from a doctor-patient relationship to a doctor-hospital relationship, where a patient's data no longer stays with the treating doctor once they change hospitals. Old-school medicine — operating only when needed, never when not needed — is what should endure through that change.
This is similar to a past case where eye pain turned out to be a neurosurgical problem — the presenting complaint pointed one way but the real cause was elsewhere. You made a related point about not confusing varicose veins with cellulitis.▼
Never confuse varicose veins with cellulitis and simply give a course of antibiotics to send the patient away — that is the wrongest possible thing to do, and it is not a constructed scenario. This happens regularly in real-life GP clinics, and any swollen leg deserves at least a Doppler ultrasound before it is written off as a skin infection.
How does the quality of the information a referring doctor sends you change the outcome for the patient?▼
Out of roughly 25 healthcare facilitators sending referrals, only one or two send a report in a structured format. A recent case arrived with mismatched patient names, ages and even genders across different files for what turned out to be the same patient — a PDF here, a broken image file there, no consolidated record. I would rather give no advice than wrong advice built on poorly collated information.
Why does a CT angiogram matter more than a radiology report when referring an aneurysm?▼
A report stating an infrarenal or suprarenal aortic aneurysm conveys almost no actionable detail. The CT angiogram itself supplies the landing zones, the maximal diameters and the vessel anatomy that determine the preferred modality of intervention, information a written summary cannot replicate.
What is the cost difference between open and endovascular aneurysm repair?▼
Open abdominal aortic aneurysm repair runs roughly USD 10,000 to 15,000. Endovascular stent graft repair runs roughly USD 45,000 to 50,000, largely because the stent graft alone costs around USD 30,000.
Is open surgical repair still a valid option for aortic aneurysms given modern endovascular techniques?▼
Yes. Time-tested open repair remains the right choice in many cases even today, and is not automatically inferior to a stent graft.
What should a referring doctor avoid when sending an aneurysm case to a vascular surgeon?▼
Avoid forwarding fancy, unsupported recommendations such as TAVI for a dilated aortic root or TEVAR without the surgeon having seen the anatomy directly. A basic recommendation is acceptable; a complex one built on a report alone is not.
