RESUMO
Arteriovenous malformations (AVMs) in mesenteric vessels are exceptionally rare. These congenital vascular anomalies lead to direct vascular flow between the highly pressured arterial system and the low-pressure venous system. We describe the case of a patient with prior left colectomy for splenic flexure colonic adenocarcinoma presenting with persistent abdominal pain after developing multiple mesenteric thromboses. CT and colonoscopy showed left hemicolon congestion, anastomotic stenosis and mucosal oedema. Mesenteric angiogram revealed AVMs in the right colic and left colic arteries. Embolisation of the left colic AVM led to symptom resolution without recurrence at interval follow-up.

A woman in her 20s presented with haematemesis, post-prandial abdominal pain, weight loss and anaemia. Imaging revealed a non-enhancing mass in the retroperitoneal space along the mesenteric plane, encasing the porto-mesenteric vasculature. Endoscopy showed oesophageal varices. She was diagnosed with sclerosing mesenteritis, causing extrinsic compression of the portal vein and superior mesenteric artery. She underwent endoscopic variceal ligation and received prednisolone and tamoxifen. After 3 months, her post-prandial pain improved, and she did not have further bleeding episodes.

BACKGROUND: This study was performed to summarize our experience in treating acute superior mesenteric artery embolism (SMAE) by percutaneous mechanical thrombectomy (PMT). METHODS: Between January 2023 and October 2023, 18 patients presenting with acute mesenteric ischemia were admitted to our center, including 11 cases of SMAE, 3 cases of superior mesenteric artery thrombosis, and 4 cases of superior mesenteric vein thrombosis. We retrospectively reviewed 8 patients (4 males and 4 females; range, 51-79 years; mean, 62.50 ± 9.67 years) who underwent treatment of acute SMAE using the AcoStream system. The patients had no obvious evidence of intestinal necrosis as shown by peritoneal puncture or computed tomography. Thrombectomy was performed on the superior mesenteric artery (SMA) using an 8F AcoStream thrombus aspiration system (Acotec, China). The demographics, risk factors, therapeutic effect, complications, mortality, and follow-up of the study population were assessed. RESULTS: The technical success rate was 100%. After 1-3 passes (2.38 ± 0.92) and aspiration thrombectomy, complete thrombus removal was achieved in 7 (87.50%) patients. One patient received an adjunctive catheter-directed thrombolysis due to partial thrombus removal. Thrombolysis was conducted for 2 days, resulting in complete resolution of the thrombus. The other 7 patients did not receive adjunctive endovascular intervention due to complete thrombus removal and no residual stenosis. No distal embolization or device-related complications were noted during the procedure. After the procedure, sufficient clinical improvement was seen in 6 patients within 1-2 days. Two patients showed no significant improvement of their symptoms. Laparotomy was performed on day 1 and day 2 after thrombectomy in patients 3 and 7, respectively. Intestinal necrosis was diagnosed operatively and intestinal resection was performed. All patients were discharged 6-15 days (9.50 ± 3.07) after admission without perioperative complication or death. The mean follow-up period was 5.00 ± 3.30 months (range, 1-10 months), and the follow-up rate was 100%. During the follow-up, all patients remained symptom-free. Computed tomography angiography images showed good flow in the trunk and branches of the SMA in all patients. CONCLUSIONS: PMT using the AcoStream system is a minimally invasive, safe, and effective technique for acute SMAE. Early application of PMT can achieve immediate revascularization of the SMA and have the potential advantage of avoiding laparotomy or reducing the extension of enterectomy, as it could theoretically restore intestinal perfusion in less time than open revascularization. If the symptoms do not improve after PMT, exploratory laparotomy should be scheduled as soon as possible. Further studies are necessary on this field to confirm these findings.

OBJECTIVE: Retrograde open mesenteric stenting (ROMS) is an alternative to mesenteric bypass in patients with acute mesenteric ischemia (AMI) with variable reported 30-day mortality rates. Large studies evaluating patient outcomes following ROMS are scarce. Our study aims to assess the results of this approach among patients presenting with AMI. METHODS: We reviewed all the patients with AMI who were treated with ROMS (2011-2022). Patient demographics, presentation, operative details, and outcomes were analyzed. Primary end points were in-hospital, 30-day, and 1-year mortality. Kaplan-Meier estimate for 1-year mortality and primary patency loss were generated. Secondary end points included postoperative 30-day complications. RESULTS: Between 2011 and 2022, ROMS was attempted on a total of 42 patients. The median age was 70 ± 15 years and the majority of patients were female. Pain out of proportion to the physical examination was the most common presenting symptom (n = 18, 42.9%) followed by peritonitis (n = 14, 33.4%). All patients underwent preoperative intravenous contrast computed tomography imaging. In situ thrombosis was identified as the etiology of AMI in 36 patients (85.7%). Technical success was achieved in 40 patients (95.2%). Conventional, non-hybrid operating rooms were used for the majority of cases. Revascularization of all 40 patients involved angioplasty and stenting of superior mesenteric artery. A single stent was placed in 35 patients (87.5%) and the reminder had more than one stent. Eighty percent of patients required bowel resection. A second-look laparotomy was required in 34 patients (85.0%). The mean operative time, including both the general surgery and vascular surgery portions of the index procedure, was 192 ± 57 minutes. Sepsis was the most common complication observed within 30 days, occurring in 8 patients (20.0%). In terms of mortality, 13 patients (32.5%) died during their index hospitalization, and 9 died (22.5%) within 30 days. On Kaplan-Meier analysis, the 1-year overall patient survival rate was 58.6%, and the primary patency rate for stents was 51.4%. CONCLUSIONS: ROMS has an excellent technical success rate in management of AMI with lower than traditionally reported mortality rates for AMI. The dual benefits of rapid revascularization and bowel evaluation should make this surgical modality an alternative approach for treatment of AMI.

OBJECTIVE: Non-vitamin K antagonist oral anticoagulants have shown similar efficacy and lower bleeding rates than vitamin K antagonists for venous thromboembolism. However, this has not been proven in mesenteric vein thrombosis. This study aimed to compare the clinical outcomes of vitamin K antagonists and non-vitamin K antagonist oral anticoagulants. METHODS: Between January 2014 and July 2022, mesenteric vein thrombosis was diagnosed on computed tomography in 225 patients in a tertiary hospital. Among them, a total of 44 patients who underwent long-term anticoagulation therapy over 3 months were enrolled in this study. Patients were divided into two groups based on the anticoagulant used: vitamin K antagonists (Group 1, n = 21) and non-vitamin K antagonist oral anticoagulants (Group 2, n = 23). The efficacy outcomes were symptom recurrence and thrombus resolution on follow-up computed tomography, and the safety outcome was bleeding complications. RESULTS: The median age of the patients was 56 years (range, 46-68 years), and 52% were men. The most common risk factors were unprovoked intra-abdominal infections (30%). The median duration of anticoagulation therapy was 13 months (20 months in Group 1 vs 6 months in Group 2; P = .076). Of the 44 patients, 17 (39%) received the standard treatment. The median follow-up period was longer in Group 1 than in Group 2 (57 vs 28 months; P = .048). No recurrence of mesenteric vein thrombosis-related symptoms were observed in either group. The median duration of follow-up computed tomography was 31 months (42 months in Group 1 vs 18 months in Group 2; P = .064). Computed tomography revealed complete thrombus resolution, partial resolution, and no changes in 71%, 19%, and 10%, respectively (P = .075). Regarding bleeding complications, varix bleeding and melena developed in two patients in Group 2, and anticoagulation treatment thereafter ceased. CONCLUSIONS: Despite the short follow-up duration in the non-vitamin K antagonist oral anticoagulants group, there was no clinically significant difference in the thrombus resolution rate or bleeding complications when compared with the vitamin K antagonists group. Although research on the long-term effects of non-vitamin K antagonist oral anticoagulants in patients is limited, non-vitamin K antagonist oral anticoagulants can be considered an alternative to conventional treatments.

INTRODUCTION: Clinical practice guidelines have recommended an endovascular-first approach (ENDO) for the management of patients with chronic mesenteric ischemia (CMI), whereas an open mesenteric bypass (OMB) is proposed for subjects deemed to be poor ENDO candidates. However, the impact of a previous failed endovascular or open mesenteric reconstruction on a subsequent OMB is unknown. Accordingly, this study was designed to examine the results of a remedial OMB (R-OMB) after a failed ENDO or a primary OMB (P-OMB) for patients with recurrent CMI. METHODS: All patients who underwent an OMB from 2002 to 2022 at the University of Florida were reviewed. Outcomes after an R-OMB (ie, history of a failed ENDO or P-OMB) and P-OMB were compared. The primary end point was 30-day mortality, whereas secondary outcomes included complications, reintervention, and survival. The Kaplan-Meier methodology was used to estimate freedom from reintervention and all-cause mortality, whereas multivariable Cox proportional hazards modeling identified predictors of death. RESULTS: A total of 145 OMB procedures (R-OMB, n = 48 [33%]; P-OMB, n = 97 [67%]) were analyzed. A majority of R-OMB operations were performed for a failed stent (prior ENDO, n = 39 [81%]; prior OMB, n = 9 [19%]). R-OMB patients were generally younger (66 ± 9 years vs P-OMB, 69 ± 11 years; P = .09) and had lower incidence of smoking exposure (29% vs P-OMB, 48%; P = .07); however, there were no other differences in demographics or comorbidities. R-OMB was associated with less intraoperative transfusion (0.6 units vs P-OMB, 1.4 units; P = .01), but there were no differences in conduit choice or bypass configuration.The overall 30-day mortality and complication rates were 7% (n = 10/145) and 53% (n = 77/145), respectively, with no difference between the groups. Notably, R-OMB had decreased cardiac (6% vs P-OMB, 21%; P < .01) and bleeding complication rates (2% vs P-OMB, 15%; P = .01). The freedom from reintervention (1 and 5 years: R-OMB: 95% ± 4%, 83% ± 9% vs P-OMB: 97% ± 2%, 93% ± 5%, respectively; log-rank P = .21) and survival (1 and 5 years: R-OMB: 82% ± 6%, 68% ± 9% vs P-OMB: 84% ± 4%, 66% ± 7%; P = .91) were similar. Independent predictors of all-cause mortality included new postoperative hemodialysis requirement (hazard ratio [HR], 7.4, 95% confidence interval [CI], 3.1-17.3; P < .001), pulmonary (HR, 2.7, 95% CI, 1.4-5.3; P = .004) and cardiac (HR, 2.4, 95% CI, 1.1-5.1; P = .04) complications, and female sex (HR, 2.1, 95% CI, 1.03-4.8; P = .04). Notably, R-OMB was not a predictor of death. CONCLUSIONS: The perioperative and longer-term outcomes for a remedial OMB after a failed intraluminal stent or previous open bypass appear to be comparable to a P-OMB. These findings support the recently updated clinical practice guideline recommendations for an endovascular-first approach to treating recurrent CMI due to the significant perioperative complication risk of OMB. However, among the subset of patients deemed ineligible for endoluminal reconstruction after failed mesenteric revascularization, R-OMB results appear to be acceptable and highlight the utility of this strategy in selected patients.

Although inferior mesenteric artery occlusion due to acute aortic dissection sometimes occurs, it is usually not considered an important finding. Herein, we present an extremely rare case of delayed bowel ischaemia due to inferior mesenteric artery occlusion in Stanford type A acute aortic dissection that highlights the need for cardiac surgeons to be mindful of inferior mesenteric artery occlusion in patients with superior mesenteric artery dissection or vascular anomalies in the mesenteric arteries.

OBJECTIVE: Endovascular and hybrid methods have been increasingly used to treat mesenteric ischemia. However, the long-term outcomes and risk of symptom recurrence remain unknown. The objective of the present study was to define the predictors of postoperative morbidity, mortality, and patency loss for acute mesenteric ischemia (AMI) and chronic mesenteric ischemia (CMI). METHODS: The inpatient and follow-up records for all patients who had undergone revascularization for AMI and CMI from 2010 to 2020 at a multicenter hospital system were reviewed. Patency and mortality were evaluated with Cox regression, visualized with Kaplan-Meier curves, and compared using log-rank testing. Patency was further evaluated using Fine-Gray regression with death as a competing risk. The postoperative major adverse events (MAE) and 30-day mortality were evaluated with logistic regression. RESULTS: A total of 407 patients were included, 148 with AMI and 259 with CMI. For the AMI group, the 30-day mortality was 31%. Open surgery was associated with lower rates of bowel resection (odds ratio [OR], 0.23; 95% confidence interval [CI], 0.13-0.61). The etiology of AMI also did not change the outcomes (OR, 1.30; 95% CI, 0.77-2.19). Adjusted analyses indicated that a history of diabetes (OR, 2.77; 95% CI, 1.37-5.61) and sepsis on presentation (OR, 2.32; 95% CI, 1.18-4.58) were independently associated with an increased risk of 30-day MAE. In the CMI group, open surgery and chronic kidney disease were associated with a higher incidence of MAE (OR, 3.03; 95% CI, 1.14-8.05; OR, 2.37; 95% CI, 1.31-4.31). In contrast, chronic kidney disease (OR, 3.02; 95% CI, 1.10-8.37) and inpatient status before revascularization (OR, 2.78; 95% CI, 1.01-7.61) were associated with increased 30-day mortality. For the CMI group, the endovascular cohort had experienced greater rates of symptom recurrence (29% vs 13%) with a faster onset (endovascular, 64 days; vs bypass, 338 days). CONCLUSIONS: AMI remains a morbid disease despite the evolving revascularization techniques. An open approach should remain the reference standard because it reduces the likelihood of bowel resection. For CMI, endovascular interventions have improved the postoperative morbidity but have also resulted in early symptom recurrence and reintervention. An endovascular-first approach should be the standard of care for CMI with close surveillance.
