Covered stent placement for gastroduodenal artery stump hemorrhage after pancreaticoduodenectomy

“Post- pancreaticoduodenectomy (PD) hemorrhage is a rare but fatal complication that accounts for 10–40% of post-operative mortality.1,2 In such patients, successful surgical
treatment is compromised due to extensive inflammatory changes caused by recent dissections. Therefore, endovascular treatment is considered as the first line treatment
especially in cases of delayed hemorrhage (occurring 24 h after surgery) from the hepatic artery (HA). Transcatheter embolization and covered stent placement are the most
common endovascular techniques. However, transcatheter embolization typically involves sacrificing the major HA, which frequently causes severe hepatic ischemia or infarction.”

Distal pancreatectomy with en bloc celiac axis resection (DP-CAR) and arterial reconstruction: Techniques and outcomes

Addeo P, Guerra M, Bachellier P. Distal pancreatectomy with en bloc celiac axis resection (DP-CAR) and arterial reconstruction: Techniques and outcomes. J Surg Oncol. 2021 Jun;123(7):1592-1598.

Full-text for Emory users.

Results: Sixty consecutive DP-CARs were reviewed. Most patients underwent induction chemotherapy (85%) based on FOLFIRINOX protocol (80.3%). The hepatic artery was reconstructed in 50 patients (83.3%). The left gastric artery was reconstructed in 4 and preserved in 14 patients. A venous resection was associated during 44 DP-CARs (36 segmental venous resections/8 lateral venous resections). Ninety days mortality was 5.0% with 48.3% (n = 29) overall rate of morbidity. Postoperative outcomes in term of mortality, morbidity, and ischemic events between patients with and without arterial reconstruction were similar despite a higher rate of venous resection (81% vs. 40%; p = 0.005) and more complex cases (Mayo clinic DP-CARs class 1B, 2A, and 3A) in the reconstructed group.

Conclusion: Arterial reconstruction represents a safe surgical option during DP-CAR to lessen postoperative ischemic events. This technique, reserved to high volume centers expert in vascular resection during pancreatectomy, deserves further comparison with standard technique in a larger setting.

RESULTS: Covered stent placement was successful in 14 of 16 patients (88%); embolization was successful in 10 of 11 (91%) patients. For the embolization group, the overall 30-day and 1-year survival rate was 70%, and the 1- and 2-year survival rate was 56%; for the covered stent group, these rates were 81% and 74%, respectively. The 30-day patency of the covered stent was 84%, and 1-year patency was 42%; clinically relevant ischemia was observed in two patients. Infarction distal to the embolized vessel occurred in 6 of 11 patients (55%).
