Recurrent Chronic Mesenteric Ischemia After Failed Endovascular Revascularization
This protocol covers patients with chronic mesenteric ischemia (CMI) who have undergone prior mesenteric revascularization, developed recurrent arterial stenosis, and continue to experience recurrent ischemic symptoms despite endovascular remedial intervention.
Clinical Scenario
Recurrent stenosis can develop after both endovascular and open mesenteric revascularization for CMI. When symptoms recur in the setting of recurrent stenosis, a remedial intervention is indicated — following the same approach as for de novo lesions, but adapted to the reoperative context.
Previous Step — Endovascular Remedial Revascularization Did Not Achieve the Goal
The preceding remedial step — endovascular-first revascularization — failed to achieve its primary goal: reversal of recurrent CMI symptoms (postprandial abdominal pain, food fear, diarrhea). Either the lesion is not amenable to an endovascular approach or the endovascular attempt has not provided durable relief. This protocol defines what comes next.
Next Step — Surgical Approach (Partial Overview)
When the endovascular option is not feasible or has failed, open surgical revascularization is the reserved next step — with the specific procedure and inflow strategy tailored to the patient's anatomy and operative history. Full surgical decision logic is available in the structured protocol.
Treatment Goal
Reversal of recurrent CMI symptoms: postprandial abdominal pain, food fear, and diarrhea.

- Patients may develop recurrent stenoses and/or recurrent symptoms after both endovascular and open revascularization for CMI.
- In patients with recurrent symptoms of CMI, we recommend remedial treatment as recommended for the de novo lesions.
- We suggest that the choice of revascularization for recurrent stenoses should be similar to the de novo lesions with the endovascular approach recommended as the initial option and open revascularization reserved for lesions not amenable to the endovascular approach.
- The remedial open revascularizations can be facilitated by using an alternative inflow source to avoid some of the challenges associated with a reoperative field (ie, convert failed retrograde bypass to antegrade bypass or vice versa).
- We recommend revascularization in patients with CMI to reverse their presenting symptoms (ie, weight loss, food fear, diarrhea, postprandial pain) and improve their overall quality of life.
