Dissection of the Celiac Trunk Is a Mild Disease.

BACKGROUND: The purpose of this study was to assess whether the presence of an aneurysmal or dissecting arterial disease was a risk factor of poor prognosis in patients presenting a dissection of the celiac trunk (CT). METHODS: All patients presenting a CT dissection between January 1, 2014, and June 30, 2022, were included. Patients with a CT dissection due to the extension of an aortic dissection were excluded. Les antécédents familiaux de dissection, de maladie anévrysmale, de maladie athéromateuse ou du tissu conjonctif, la pratique d'une activité physique ou sportive, un effort inhabituel les jours précédant la dissection ainsi qu'un traumatisme étaient recherchés. Family history of dissection, aneurysmal disease, atheromatous or connective tissue disease, physical activity or sport, an unusual effort in the days prior to the dissection and trauma were sought after. Ischemic or aneurysmal complications in the acute phase and the evolution of the dissection were evaluated and compared between patients with an isolated dissection and those presenting an aneurysmal or dissecting arterial disease. RESULTS: 45 patients were included in the study. Twenty-three (51.1%) patients presented with symptomatic CT dissection, and 22 (48.9%) with asymptomatic CT dissection. All the patients initially had medical management alone. The mean follow-up was 32 ± 25 months and all patients were asymptomatic at the time last news. 24 (53.3%) presented an isolated CT dissection, and 21 (46.7%) a CT dissection associated with aneurysmal or dissecting arterial disease. There was no significant difference between patients with an isolated CT dissection and those with an associated dissecting or aneurysmal pathology. CONCLUSIONS: CT dissection is a stable disease in the midterm, which makes it a mild arterial pathology, with or without aneurysmal or dissecting anomalies in another territory. The mechanical stress exerted on the CT by the arcuate ligament could be responsible for parietal trauma and favor the occurrence of a CT dissection.

Percutaneous Axillary Artery Puncture: An Efficient Approach for Upper Extremity Access.

BACKGROUND: The aim was to analyze the anatomic feasibility of the percutaneous axillary access (PAXA) using cadaverous models and then to analyze the complications associated with PAXA during Fenestrated or Branched Endovascular Aneurysm Repair (F/BEVAR) procedures. METHODS: Cadaverous models were used to analyze axillary pedicle after a PAXA on an initial anatomical investigation. A subclavian approach was performed after puncture to assess the injuries caused by the needle. Then, in an observational study, patients who underwent F/BEVAR using a PAXA between July 2019 and July 2021 were included. PAXA-related events and complications were monitored. RESULTS: Eleven dissections were performed on cadavers. The axillary vein was injured twice (18.2%); the puncture site on the axillary artery was found on the arterial proximal part, behind the clavicle. Fifty-three patients underwent a F/BEVAR using a PAXA. The mean (SD) age of patients was 74.5 (9.7) years. Most indications for endovascular repair were para-renal aneurysms (66%). Two Proglide® closure devices served to close arterial access in all procedures. Adjunct balloon inflation was used in 19 (35.8%) patients. There were 5 (9.4%) PAXA-related events included preoperative blush in 2 (3.8%) patients, axillary artery dissection in 2 (3.8%), and 1 (1.9%) axillary artery stenosis. Five patients (9.4%) had a postoperative axillary hematoma without need for additional surgical procedure. No PAXA-related complication was found after discharge (mean [SD] 11.7 [7.4] months following surgery). CONCLUSIONS: Percutaneous axillary artery access was an efficient upper extremity access and associated with a low rate of PAXA-related events.

American Society of Anesthesiologists-Physical Status Classification As An Independent Risk Factor of Surgical Site Infection After Infra-Inguinal Arterial Bypass.

OBJECTIVES: The present study aimed to assess whether high-risk American Society of Anesthesiologists (ASA)-Physical Status was an independent risk factor for the development of surgical site infection (SSI) after infra-inguinal lower extremity bypass (LEB). SUMMARY OF BACKGROUND DATA: The ASA-Physical Status Classification System assesses the overall physical status preoperatively. ASA-Physical Status is associated with postoperative morbidity and mortality. However, limited data are available on how ASA-Physical Status Class affects the development of SSI after infra-inguinal LEB. METHODS: Patients who had undergone infra-inguinal LEB from January 1, 2015 to December 31, 2018, for obliterative arteriopathy or popliteal aneurysm at our university hospital were included. SSI risk factors were identified using multivariable logistic regression. The length of hospital stay, major limb events (MALE), major adverse cardiovascular events (MACE), and all-cause mortality were compared for patients with SSI versus those without SSI 3 months and 1- year of follow-up after the index surgery. RESULTS: Among the 267 patients included, 30 (11.2%) developed SSI during the 3-month period and 32 (12%) at 1 year. ASA-Physical Status ≥3 [odds ratio (OR): 3.7, 95% confidence interval CI) 1.5-11.1], emergency surgery (OR: 2.7, 95% CI 1.2-6.0), general anesthesia (OR: 2.8, 95% CI 1.3-6.1), and procedure performed by a junior surgeon (OR: 2.7, 95% CI 1.3-6.0) were independently associated with SSI. At 3 months and 1 year, SSI was significantly associated with MALE (including surgical wound debridement, subsequent thrombectomy, major amputation), length of hospital stay, and all-cause mortality. CONCLUSION: The ASA-Physical Status should be considered in medical management when an infra-inguinal LEB is considered in frail patients, to prevent surgical complications.

EndoSuture aneurysm repair versus fenestrated aneurysm repair in patients with short neck abdominal aortic aneurysm.

OBJECTIVE: The aim of this study was to compare midterm results of EndoAnchors in EndoSuture aneurysm repair (ESAR) versus fenestrated endovascular aneurysm repair (FEVAR) in short neck abdominal aortic aneurysm (AAA). METHODS: All patients who underwent an ESAR procedure for a short neck AAA at our center between September 2017 and May 2020 were considered for analysis. To form the control group, preoperative computed tomography angiography of patients who underwent FEVAR for juxtarenal AAA between April 2012 and May 2020 were reviewed and patients who met short neck criteria selected. A propensity-matched score on neck length and neck diameter was calculated, resulting in 18 matched pairs. AAA shrinkage, type Ia endoleaks (EL), AAA-related reinterventions, and AAA-related deaths were compared. RESULTS: The median AAA diameter was 54 mm (interquartile range [IQR], 52-61 mm) versus 58 mm (IQR, 53-63 mm) with a median neck length of 8 mm (IQR, 6-12 mm) vs 10 mm (IQR, 6-13 mm) in ESAR and FEVAR patients, respectively. Technical success was 100% in both groups. Procedural success was 94% in the ESAR group versus 100% in the FEVAR group. The median procedure duration was 138 mm (IQR, 113-182 mm) vs 240 mm (IQR, 199-293 mm) ( P < .001) and the median length of stay was 2 days (IQR, 2-3 days) vs 7 days (IQR, 6-7 days) (P < .001) in ESAR and FEVAR patients, respectively. No major hospital complications were observed in ESAR patients compared with two in FEVAR patients (11%) with one transient acute kidney injury and one transient paraplegia. The median follow-up was 23 months (IQR, 19-33 months) vs 36 months (IQR, 22-57 months) with 67% versus 61% AAA shrinkage in the ESAR and FEVAR groups, respectively (P = .73). No type Ia EL, proximal neck-related reinterventions, or AAA-related deaths were observed in either group. No AAA-related reintervention was observed in the ESAR group versus three reinterventions in the FEVAR group (P = .23). CONCLUSIONS: ESAR seems to be a safe technique with no major postoperative complications or reinterventions observed during follow-up. It seems to offer similar midterm results as FEVAR in terms of type Ia EL, aneurysm shrinkage, and aneurysm-related mortality. ESAR seems to be a good off-the-shelf alternative to FEVAR in case of technical constraints.

Natural History of Asymptomatic Superior Mesenteric Arterial Stenosis Depends on Coeliac and Inferior Mesenteric Artery Status.

OBJECTIVE: The benefit of preventive treatment for superior mesenteric artery (SMA) stenosis remains uncertain. The latest European Society for Vascular Surgery (ESVS) guidelines remain unclear given the lack of data in the literature. The aim of this study was to evaluate asymptomatic SMA stenosis prognosis according to the presence of associated coeliac artery (CA) and/or inferior mesenteric artery (IMA) stenosis. METHODS: This was a single academic centre retrospective study. The entire computed tomography (CT) database of a single tertiary hospital was reviewed from 2009 to 2016. Two groups were defined: patients with isolated > 70% SMA stenosis (group A) and patients with both SMA and CA and/or IMA > 70% stenosis (group B). Patient medical histories were reviewed to determine the occurrence of mesenteric disease (MD) defined as development of acute mesenteric ischaemia (AMI) or chronic mesenteric ischaemia (CMI). RESULTS: Seventy-seven patients were included. Median follow up was 39 months. There were 24 patients in group A and 53 patients in group B. In group B, eight (10.4%) patients developed MD with a median onset of 50 months. AMI occurred in five patients with a median of 33 months and CMI in three patients with a median of 88 months. Patients of group B developed more MD (0% vs. 15.1%; p = .052). The five year survival rate was 45% without significant difference between groups. CONCLUSION: Patients with SMA stenosis associated with CA and/or IMA seem to have a higher risk of developing mesenteric ischaemia than patients with isolated SMA stenosis. Considering the low life expectancy of these patients, cardiovascular risk factor assessment and optimisation of medical treatment is essential. Preventive endovascular revascularisation could be discussed for patients with non-isolated > 70% SMA stenosis, taking into account life expectancy.

Analysis of Preoperative CT Scan Can Help Predict Technical Failure of Endovascular Treatment of TASC C-D Aortoiliac Chronic Total Occlusions.

BACKGROUND AND AIMS: To evaluate if features of occlusion analyzable on preoperative computed tomography scan could predict risks of technical failure or iliac rupture of endovascular treatment of TransAtlantic InterSociety Consensus C-D aortoiliac chronic total occlusion. METHODS AND RESULTS: All patients treated by endovascular techniques for a TransAtlantic InterSociety Consensus C-D aortoiliac chronic total occlusion between 2009 and 2016 were included (107 patients, 148 iliac arteries). We evaluated the location of the occlusion and the importance of the arterial calcifications. For this factor, patients were divided into 3 groups: the Black occlusion group with mild or no calcifications, the white occlusion group with moderate no protrusive calcifications, and the white protrusive occlusion group with heavy endoluminal calcifications. Technical failure occurred in 11 iliac arteries and peroperative iliac rupture in 6. The location in the external iliac artery is the most significate risk factor of technical failure in univariate (OR = 9.93; P = 0.0012) and multivariate analysis (OR = 15.26; P = 0.0006). The presence of heavy endoluminal calcifications is a further significate risk factor (OR = 13.88; P = 0.0365). Rupture rate was comparable between the 3 groups. CONCLUSIONS: Preoperative computed tomography scan can predict risk of technical failure but not of iliac rupture.

Revascularization of Isolated Superior Mesenteric Artery Dissection for Post-Mesenteric Infarction Exudative Enteropathy: The Contribution of a Multidisciplinary Care Teamwork.

BACKGROUND: Isolated dissection of the superior mesenteric artery (SMA) is increasingly diagnosed; the conservative treatment appears to be the best option when blood supply is maintained. However, some patients require a more invasive attitude, due to acute or chronic ischemic complication. Multidisciplinary care within a health-care network improves medical and surgical support. We present a case of chronic complication of isolated SMA dissection requiring a revascularization, followed by bowel resection. CASE PRESENTATION: A 49-year-old man presented abdominal pain secondary to necrotizing enterocolitis of unknown cause. An isolated small bowel resection with immediate restoration of continuity was first performed to remove the necrotic tissue. The patient developed post-ischemic exudative enteropathy and small intestinal bacterial overgrowth (SIBO). Re-examination of the first computed tomography (CT) scan revealed an isolated dissection of the SMA that had not been diagnosed. The patient was then successfully treated by superior mesenteric revascularization, and after recovering, he underwent small bowel resection for chronic ischemia. CONCLUSIONS: SMA revascularization has to be performed in case of SMA dissection complicated of bowel ischemia. Enteropathy is a rare complication of chronic mesenteric ischemia requiring digestive and vascular management in a dedicated health-care team.
