CMI / Chronic mesenteric ischemia

• Chronic mesenteric ischemia = rare / challenging clinical entity
• Vascular patients
• Most surgeons have limited experience with the management of symptomatic
• cclusive disease of the superior mesenteric artery or coeliac trunk.
• An endovascular-first strategy :

– Less invasive character, – lower peri-procedural morbidity and mortality – more rapid recovery.

• Volume stenting increased
• Long-term results of percutaneous mesenteric angioplasty and stenting are worse

than those obtained with open surgery.

• Many centres reserve open repair for cases in whom PTA failed.

Diagnosis / CMI

• Chronic mesenteric ischemia (CMI) is the result of insufficient mucosal perfusion of the

gastrointestinal tract.

• The diagnosis of CMI is established by multidisciplinary consensus and confirmed if

successful therapy results in symptom relief.

• low-risk, intermediate-risk and high-risk patients for CMI.
• The most common cause of isolated celiac artery (CA) stenosis is compression of the

CT by the median arcuate ligament (median arcuate ligament syndrome (MALS)).

Incidence

• The exact incidence of CMI is unknown, since population-based

studies are lacking.

• However, the number of CMI patients undergoing revascularization

procedures is increasing significantly according to data from the United States: 1.8 per million in 2000 to 5.6 per million in 2012 (p<0.01)).

acute / Chronic mesenteric ischemia

Focal / complex desease

Does the early benefit and better safety profile of minimally invasive endovascular mesenteric revascularisation offset its lower long-term patency?

• For most authors, the balance between the early benefit, in terms of safety, and the

late risk of reintervention after endovascular mesenteric procedures, is considered as a reasonable trade-off, favouring endovascular over open approach.

ENDO > OR

Endo vs OR Metanalysis

• 100 observational studies (22 comparative, 78 noncomparative; 18,726 patients; mean age,

69 years).

• OR associated with a statistically significant:

– increase in the risk of in-hospital complications (relative risk [RR], 2.2; 95% confidence interval [CI], 1.8-2.6) and – Non significant increase in mortality at 30 days (RR, 1.57; 95% CI, 0.84-2.93). – lower risk of 3-year recurrence rates (RR, 0.47; 95% CI, 0.34-0.66) – similar 3-year survival. CONCLUSIONS:

• EnDO may offer better early outcomes than OR
• although this effect may not be durable.
• Long-term mortality appears to be similar.

Need for reinterventions

• The higher need for reintervention after mesenteric

artery stenting does not influence long-term survival

ENDO vs OR

• No randomized controlled trials,
• 15475 patients CMI (2000–2014)
• Endo 70%
• OR 30%
• lower in-hospital mortality for ENDO: 2.4% versus 8.7% OR
• shorter length of stay for ENDO: 6.4 days versus 14 days OR
• lower hospitalisation cost for ENDO 21,686 $versus 42,974 $ OR
• ENDO advantage in better early outcome,
• OR: 7.2 odds for in-hospital mortality.

Covered stents vs BMS

• Covered (n1/442) vs BMS (n1/4147) 1
• superior performance of covered stents at 29-month followup, in

terms of:

• less restenosis (8% versus 47%),
• less symptom recurrence (8% versus 50%)
• less need for reintervention (9% versus 44%)
• 2-year significant restenosis rate of 11% for covered compared with

34% for bare-metal stents 2

• CS / BMS:
• higher freedom from restenosis (92% ± 6% vs 53% ± 4%; P = .003),
• symptom recurrence (92 ± 4% vs 50 ± 5%; P = .003),
• reintervention (91% ± 6% vs 56% ± 5%; P = .005),
• better primary patency at 3 years (92% ± 6% vs 52% ± 5%; P < .003).
• Secondary patency rates were similar in both groups.
• CONCLUSIONS:
• In this nonrandomized study, CS were associated with less restenosis, recurrences, and

reinterventions than BMS in patients undergoing primary interventions or reinterventions for CMI.

Is there any place for open surgery?

• For young low-risk patients, <50 years old
• OR revascularisation has authors’

preference

• Most durable vascular repair to the patient
• With a 85% 10-year primary patency rate

Should multiple mesenterial vessels be repaired (combined CT and SMA revascularisation)?

• When CT and SMA are both significantly stenosed,
• > 70%
• it is preferable to revascularise both arteries.

Is prophylactic intervention on asymptomatic stenosis

• f the mesenteric or coeliac artery justified?
• Resist the temptation to treat asymptomatic stenosis of the CT/ SMA often an

incidental finding on abdominal computed tomography.

• Splanchnic vasculature is characterised by its plasticity and rich collateral

network between the three main mesenterial vessels

• A solitary mesenteric artery stenosis is often well tolerated and does not

routinely requires a revascularisation procedure

Conclusions

• CMI is not so rare and has a high mortality
• A multidisciplaniry team discussion is needed to confirm the

best therapeutic option

• The diagnosis is offen difficult but the Score risk need to be

used

• Endo is the reference treatment for patients > 50 years
• OR is a durable solution for patients < 50 years
• Covered stents have better results than BMS
