Laparoscopic median arcuate ligament release using an anterior approach for median arcuate ligament syndrome.

Median arcuate ligament syndrome (MALS) is a rare condition characterized by nonspecific symptoms, such as abdominal pain, nausea, and vomiting. Furthermore, the development and rupture of pancreaticoduodenal artery aneurysms pose a potentially fatal risk. Median arcuate ligament release (MALR) is useful in the treatment of MALS, with most procedures performed laparoscopically. However, detailed descriptions of laparoscopic MALR (lap-MALR) procedures are rare. In this study, we performed lap-MALR via an anterior approach with dissection of the right lateral wall of the celiac artery (CA). For optimal visualization of the right side of the CA, the right branch of the inferior phrenic artery was divided. We believe that this procedure allows the MAL to be released within a sufficient surgical field and without excess or deficiency. Here, we present the details of six patients who underwent lap-MALR for varying indications; three for pancreaticoduodenal artery aneurysms due to CA obstruction (unruptured, n = 1; ruptured, n = 2), two cases prior to hepato-biliary-pancreatic surgery, and one symptomatic case. In all cases, lap-MALR was performed as described above, and the CA stenosis was successfully released. Our case series demonstrates the safety and reliability of our lap-MALR procedure in the treatment of MALS-related disorders, including pancreaticoduodenal artery aneurysms associated with CA compression.

Successful Management of a Patient with an Aneurysm of the Inferior Pancreaticoduodenal Artery Complicated by Severe Bleeding

Retroperitoneal bleeding is a rare and life-threatening condition for which early diagnosis and proper treatment are of paramount importance. Currently, there are sparse literature data on this issue that provide limited info on the management of such patients. The paper presents a case of successful management of a patient with an aneurysm of the inferior pancreaticoduodenal artery, complicated by recurrent bleeding into the retroperitoneal space with severe blood loss.

Visceral Artery Aneurysms in the Presence of Upstream Stenoses.

Background: Sutton-Kadir syndrome describes a rare pathology that commonly includes an aneurysm of the inferior pancreaticoduodenal artery in combination with a celiac trunk stenosis or occlusion, often caused by median arcuate ligament compression. Several therapeutic approaches exist including open surgical, endovascular, and hybrid treatments. Other combinations of visceral artery aneurysms and upstream stenoses exist but the cumulative body of evidence on these combinations is weak due to their rarity. Methods: A retrospective analysis of patient data from a single center was carried out. Electronic patient records were filtered for keywords including "visceral aneurysm", "Sutton-Kadir", and "median arcuate ligament". Imaging studies were re-examined by two blinded vascular surgeons with a third vascular surgeon as a referee in case of diverging results. Results: Sixteen patients had a visceral artery aneurysm with an upstream stenosis. All cases had a celiac trunk obstruction while one patient also had a concomitant superior mesenteric artery stenosis. Both median arcuate ligament compression and atherosclerotic lesions were identified. The location of the aneurysms varied even though the inferior pancreaticoduodenal artery was most frequently affected. A classification system based on the different combinations of stenoses and aneurysms is presented and introduced as a new pathologic entity: visceral artery aneurysm in the presence of upstream stenosis (VAPUS). Conclusions: The concomitant presence of visceral artery aneurysms, especially in the pancreaticoduodenal arteries, and blood flow impairment of the celiac axis or superior mesenteric artery is a rare pathology. The proposed VAPUS classification system offers an accessible and transparent route to the precise localization of the affected vessels.

Spontaneous complete regression of pancreaticoduodenal artery aneurysms with celiac artery occlusion after aorto-splenic bypass without additional treatment: a case report

BackgroundPancreaticoduodenal artery aneurysm (PDAA) is a rare, but fatal disease. However, the association between aneurysm size and the risk of rupture remains unclear. There are many options for therapeutic strategies that should be discussed well because the treatment options are often complicated and highly invasive. However, it remains unclear whether additional endovascular therapy is essential for all patients undergoing bypass surgery. Here, we present a case of triple PDAAs with celiac axis occlusion and spontaneous complete regression of inferior PDAAs (IPDAA) after aneurysmectomy of superior PDAA (SPDAA) and aorto-splenic bypass.Case presentationA 68-year-old woman presented with one SPDAA and two IPDAAs caused by celiac axis occlusion. Aneurysmectomy for IPDAAs was difficult because of their anatomical location and shape. Therefore, we planned a two-stage hybrid therapy. The patient underwent aorto-splenic bypass and resection of the SPDAA. Follow-up CT was performed to evaluate the IPDAAs before planned endovascular embolization. Spontaneous regression of the IPDAAs and normalized PDA arcade decreased the blood flow in the PDA arcade. The patient is doing well without graft occlusion, and the IPDAAs have completely regressed 7 years after surgery.ConclusionNormalization of hyperinflow to the PDA arcade can lead to the regression of PDAA. Potentially, additional endovascular therapy may not be required in all cases when dilation of the PDA improves. However, more cases must be accumulated to establish criteria for predicting the risks of short- and long-term PDAA ruptures.

Presentation and management of true aneurysms of the pancreaticoduodenal arcade with concomitant celiac artery stenosis using the endovascular approach

True aneurysms of the pancreaticoduodenal artery (PDA) arcade are rare but require intervention due to the high risk of rupture. Historically, these aneurysms have been managed with open surgical methods. In this study, we describe a contemporary series of aneurysms treated using a modern approach that includes endovascular and hybrid techniques. All the patients with aneurysms of the PDA arcade in an institutional database were identified between 2008 and 2022. Patients with history of pancreatic resection were excluded. Data on demographics, presenting symptoms, imaging findings, operative approach, and outcomes were collected and reviewed. There were nine patients diagnosed with a PDA aneurysm, and all nine underwent endovascular intervention. Most were men (n = 5; 55.6%) and White (n = 7; 77.8%) and had American Society of Anesthesiologists class II or III. The median aneurysm size was 21 mm (range, 6-42 mm), and five (55.5%) were symptomatic. Of the five symptomatic cases, two presented with rupture and were treated urgently. The median time to intervention for the nonurgent cases was 30 days. All but one patient had concomitant celiac artery stenosis and two of the eight cases (25%) were due to extrinsic compression from median arcuate ligament syndrome. Both patients underwent median arcuate ligament syndrome release before endovascular intervention. Another patient required open surgical bypass before endovascular repair from the supraceliac aorta to hepatic artery using a Dacron graft to maintain hepatic perfusion. Among the eight patients with celiac axis stenosis, five (62.5%) required celiac stent placement within the same operation. Coil embolization of the aneurysm was used for all except for two patients (n = 7 of 9; 77.8%), with one patient receiving embolic plugs and another receiving an 8 × 38-mm balloon-expandable covered stent for aneurysm exclusion. The median operating room time was 134 minutes. All repairs were technically successful without any intraoperative or postoperative complications. The mean follow-up was 30 months. There was no morbidity, mortality, or unplanned secondary reinterventions within 6 months after aneurysm repair. Stent patency and aneurysm size remained stable at 2 years of follow-up. True pancreaticoduodenal artery arcade aneurysms can be safely and effectively treated using endovascular and hybrid techniques. Because many of these aneurysms have concomitant celiac artery stenosis, the use of endovascular technology allows for simultaneous treatment of both the aneurysm and the stenosis with exceptional results.

Inferior Pancreaticoduodenal Artery Pseudoaneurysm Causing Biliary Obstruction: A Case Report.

Visceral arterial aneurysms and pseudoaneurysms are rare but dangerous pathologies, with reported incidence of 0.01-0.2% of the worldwide population, as found on autopsy. Pancreaticoduodenal artery pathology accounts for approximately 2% of all visceral aneurysms; it is commonly caused by chronic inflammatory processes, such as pancreatitis or adjacent pseudocysts. Morbidity and mortality commonly result from rupture of the aneurysm itself, leading to life-threatening hemorrhage into the peritoneum or gastrointestinal tract. Here we present the case of a 64-year-old male patient with previous history of alcohol use disorder leading to chronic pancreatitis and prior embolization of an inferior pancreaticoduodenal pseudoaneurysm, who presented to the emergency department (ED) with abdominal pain, nausea, and vomiting, and was found to have a large recurrent inferior pancreaticoduodenal pseudoaneurysm with associated obstructive cholangitis and pancreatitis via contrast-enhanced computed tomography (CT) of the abdomen and pelvis. The patient was managed emergently by interventional radiology angiography with embolic coiling and percutaneous biliary catheter placement, and he subsequently underwent biliary duct stenting with gastroenterology. The patient was successfully discharged after a brief hospitalization after resolution of his pancreatitis and associated hyperbilirubinemia. Pancreaticoduodenal artery aneurysms and pseudoaneurysms are rare and dangerous visceral pathologies. Patients can be diagnosed rapidly in the ED with CT imaging and need urgent endovascular management to prevent morbidity and mortality.

Sutton-Kadir Syndrome can be treated safely with endovascular embolisation alone.

Sutton-Kadir Syndrome (SKS) describes true inferior pancreaticoduodenal artery (IPDA) aneurysms in the setting of coeliac artery (CA) stenosis or occlusion. Although rare, SKS aneurysms can rupture and cause morbidity. Due to its rarity and lack of controlled treatment data, correct treatment for the CA lesion is currently unknown. Our aim was to assess if endovascular embolisation alone was safe and effective in treatment of SKS aneurysms, in emergent and elective settings. Secondary objectives were to describe presentation and imaging findings. A retrospective cohort study of patients treated at Sir Charles Gairdner Hospital between January 2014 and December 2021 was done. Data on presentation, diagnostics, aneurysm characteristics, CA lesion aetiology, treatment and outcomes were extracted from chart review. Twenty-four aneurysms in 14 patients were identified. Rupture was seen in 7/15 patients. Most aneurysms (22/24) were in the IPDA or one of its anterior or posterior branches. Median arcuate ligament (MAL) compression was identified in all. There was no difference in median (IQR) maximal transverse diameter between ruptured and non-ruptured aneurysms (6 mm (9), 12 mm (6), P = 0.18). Of ruptures, 6/7 had successful endovascular embolisation and 1/7 open surgical ligation. Of non-ruptures, 6/7 had successful endovascular embolisation, 1/7 open MAL division then endovascular CA stenting and aneurysm embolisation. No recurrences or new aneurysms were detected with computed tomography or magnetic resonance angiography over a median (IQR) follow-up period of 30 (10) months in 12 patients. Endovascular embolisation of SKS aneurysms without treatment of MAL compression is safe and effective in both the emergent and elective settings.

Clinical Characteristics and Management of Peripancreatic Arterial Aneurysms: A 20-year Experience.

Pancreaticoduodenal and gastroduodenal artery aneurysms (PDAAs and GDAAs) are rare visceral aneurysms. Considering the rupture risk regardless of size, treatment should be provided promptly. We reviewed the characteristics and management of peripancreatic aneurysms in a retrospective, single-center review of consecutive patients with PDAAs and GDAAs between 2000 and 2022. Demographics, clinical characteristics, radiologic features, treatment, and outcomes were recorded. Nineteen PDAAs and seven GDAAs were identified in 24 patients. The median sizes of the PDAAs and GDAAs were 21mm (range: 8-50mm) and 14mm (range: 11-32mm), respectively. There were 4 ruptured cases (15.4%). Ten aneurysms (38.5%) had concomitant visceral aneurysms, and 16 (61.6%) were associated with celiac pathology. Aneurysms were managed using endovascular in 12 (46.2%), surgical in 4 (15.4%), and combined methods in 3 (11.5%) cases; 7 patients (26.9%) were lost to follow-up or refused treatments. During a median 13.8-month follow-up (range: 1-147.6), two complications (7.7%) occurred including pancreatitis and coil migration into the superior mesenteric artery after embolization within 30 days. After 30 days, aorto-common hepatic artery bypass graft stenosis was identified in one PDAA. Depending on the characteristics of peripancreatic aneurysms, endovascular, surgical, and hybrid approaches might all be practical treatment options.

Obstructive jaundice as a rare complication of multiple pancreaticoduodenal artery aneurysms due to median arcuate ligament syndrome: a case report and review of the literature

BackgroundObstructive jaundice has various causes, and one of the rarest is pancreaticoduodenal artery aneurysm (PDAA), which is often associated with celiac axis stenosis caused by median arcuate ligament syndrome (MALS).Case presentationThe patient was a 77-year-old Azeri woman who presented with progressive jaundice, vague abdominal pain, and abdominal distension from 6 months ago. The intra- and extrahepatic bile ducts were dilated, the liver's margin was slightly irregular, and the echogenicity of the liver was mildly heterogeneous in the initial ultrasound exam. A huge cystic mass with peripheral calcification and compressive effect on the common bile duct (CBD) was also seen near the pancreatic head, which was connected to the superior mesenteric artery (SMA) and had internal turbulent blood flow on color Doppler ultrasound. According to the computed tomography angiography (CTA) findings, the huge mass of the pancreatic head was diagnosed as a true aneurysm of the pancreaticoduodenal artery caused by MALS. Two similar smaller aneurysms were also present at the huge aneurysm's superior margin. Due to impending rupture signs in the huge aneurysm, the severe compression effect of this aneurysm on CBD, and the patient's family will surgery was chosen for the patient to resect the aneurysms, but unfortunately, the patient died on the first day after the operation due to hemorrhagic shock.ConclusionIn unexpected obstructive jaundice due to a mass with vascular origin in the head of the pancreas, PDAA should be considered, and celiac trunk should be evaluated because the main reason for PDAA is celiac trunk stenosis or occlusion by atherosclerosis or MALS. The treatment method chosen (including transarterial embolization, open surgery, or combined method) depends on the patient's clinical status and radiological findings, but transarterial embolization would be safer and should be used as a first-line method.

Pancreaticoduodenal Artery Aneurysm Complicated by Median Arcuate Ligament Syndrome.

To highlight median arcuate ligament syndrome as a potential cause for celiac artery stenosis and pancreaticoduodenal artery aneurysm, and describe treatment options in this setting. A 63-year-old male presented with a pancreaticoduodenal artery aneurysm and concomitant celiac artery stenosis that was treated with celiac artery stenting and aneurysm coiling. He subsequently developed stent fracture and celiac artery occlusion secondary to previously unrecognized median arcuate ligament syndrome causing reperfusion of the aneurysm. This was treated with open median arcuate ligament release and aorta to common hepatic artery bypass with good clinical result and stable 20-month surveillance imaging. It is critical to recognize median arcuate ligament syndrome as a cause of celiac artery stenosis in the setting of pancreaticoduodenal artery aneurysm given the high risk of failure of endovascular stenting. Open aorto-hepatic artery bypass and endovascular aneurysm coiling should be the preferred approach in these patients.

Interventional Radiology for High-Flow Aneurysm of the Pancreaticoduodenal Arcades with Median Arcuate Ligament Syndrome: Review of 14 Patients.

Transarterial embolization (TAE) for high-flow pancreaticoduodenal artery (PDA) aneurysms in patients with celiac-trunk stenosis by the median arcuate ligament (MAL) has been found effective both after rupturing and to prevent rupture. The objective was to describe the TAE techniques used and their effectiveness in excluding PDA aneurysms due to MAL syndrome. This single-center retrospective study done at the Dijon-Bourgogne University Hospital included all patients treated by TAE in 2010-2022 for ruptured or unruptured high-flow PDA aneurysms caused by MAL syndrome. We identified 14 patients (7 women and 7 men; mean age, 64 years). Packing and trapping techniques were used alone or together. Occlusion was with microcoils, co-polymer, or cyanoacrylate glue, used separately or combined. Technical success was achieved in 13 (93%) patients. Clinical success was achieved in 12 (86%) patients. One major and two minor complications were recorded within the first 30 days. No complications occurred after 30 days. Follow-up ranged from 1 to 84 months. No cases of aneurysm recanalization have been recorded to date. TAE had high technical and clinical success rates in our patients with unruptured or ruptured PDA aneurysms due to MAL syndrome.

A Ruptured Inferior Pancreaticoduodenal Artery Aneurysm Detected With Ultrasonography: A Case Report

Pancreaticoduodenal artery aneurysm (PDAA) is a rare disease that is recognized as an intra-abdominal hemorrhage differential diagnosis. This case study reports on a ruptured PDAA case in which ultrasonography (US) proved useful for the initial diagnosis. A 60-year-old man presented to the emergency department with pain in the epigastrium and back. An abdominal US performed at presentation suggested a PDAA and intraperitoneal hemorrhage/retroperitoneal hematoma. In addition, a contrast-enhanced computed tomogram (CT) revealed a hematoma extending from the upper abdomen to the pelvic floor and an aneurysmal pancreaticoduodenal artery arcade dilatation. Furthermore, emergency abdominal angiography findings revealed bleeding from a posterior-inferior PDAA, and coil embolization was performed. Postoperative progress was good, and the postoperative CT at 7 days showed no rebleeding signs and/or enlargement or new PDAA development. Therefore, the patient was discharged from the hospital 14 days after embolization.

TREATMENT OF PATIENTS WITH CHRONIC PANCREATITIS COMPLICATED BY PANCREATORAGIA.

The aim: To present and share our experience in the treatment of pancreatoragia which could help to prevent pancreatoragia in patients with chronic pan¬creatitis in the pre- and postoperative period. Materials and methods: Surgical treatment of complicated chronic pancreatitis (CP) was performed on 249 patients in the surgical clinic of the medical faculty №2 of National Pirogov Memorial Medical University of Vinnytsia during 2000 - 2021. Pancreatorrhagia occurred in 6 (2.4%) patients, group A - 3 (1.2%) - as disease manifestation, group B - 3 (1.2%) - as complication after surgery. In group A the source of bleeding was the lower pancreato-duodenal artery: 2 (0.8%) had lower pancreaticoduodenal artery aneurysms with bleeding into the cyst, 1 (0.4%) - a year after previously performed pancreato-duodenal resection. In group B pancreatorrhagia developed in 3 (1.2%) patients after the Frey-Izbitsky local resection of the pancreas: 2 (0.8%) - from pancreato-jejuno anastomosis, 1(0.4%) - from pancreatopleural fistula. Conclusions: Pancreatoragia, as a manifestation of chronic pancreatitis, occurred in 6 (2.4%) patients. Bleeding occurred as a manifestation of the disease in 3 (1.2%) patients and in 3 (1.2%) patients - in the postoperative period. It is possible to use fibrin or cyanoacrylate glue to filling the defect of the pancreatic duct or to suture vessels in the parenchyma of the pancreas by PDS for the prevention of pancreatoragia in the postoperative period.

Recurrent IPDA Aneurysm from Celiac Occlusion Treated by a Flow Diverting Stent

AbstractInferior pancreaticoduodenal artery (IPDA) aneurysms have been associated with celiac axis stenosis and occlusion. Retrograde flow through the IPDA arcade has been hypothesized to cause enlargement of these vessels and lead to aneurysm formation. However, objective proof of this hypothesis is lacking, given the fact that celiac stenosis or occlusion and IPDA aneurysms are typically diagnosed concurrently and recurrent aneurysms have not been described. This report presents a patient with celiac axis stenosis and an IPDA aneurysm treated with median arcuate ligament lysis, celiac stenting, and aneurysmectomy. Seventeen years later, he developed a second IPDA aneurysm treated with a flow diverting stent.

Calcified pancreatoduodenal artery aneurysm with filiform celiac stenosis: Follow up for ~6 years (70 months) with no intervention

A 72-year-old male patient was investigated with abdominal ultrasound (US) imaging before the coronary artery bypass graft surgery (CABG). The incidental finding on ultrasound was an aneurysm of the superior mesenteric artery branch. Consequent CT angiography confirmed aneurysm of the inferior pancreaticoduodenal artery (PDAA, size = 25,5x31,0x28,5mm) with filiform celiac artery stenosis. According to the European Guideline asymptomatic >25mm sized PDAA are treated with an urgent repair. However, the discrepancy between PDAA size and risk of rupture and individual parameters of the patient led the multifunctional team to assign regular follow-ups with US imaging. This case report describes rare pathology, which has been followed up for the last ~6 years (70 months) annually with no intervention, and discusses complexities in making decisions in the management of PDAA with celiac artery stenosis.

Giant True Inferior Pancreaticoduodenal Artery Aneurysm Associated with Celiac Axis Occlusion

Giant visceral artery aneurysms are uncommon. Branch vessel aneurysms, particularly of the pancreaticoduodenal territory are challenging to treat due to their location, anatomy, and access to an aneurysm. While open surgical resection is associated with significant morbidity, endovascular treatment is becoming increasingly mainstream. The utilization of coil embolization, particularly in the setting of rupture has been well described. Access and platform in these settings often involve the celiac axis. We describe unusual care of a large inferior pancreaticoduodenal aneurysm and associated retroperitoneal bleed, being fed through an ectatic superior mesenteric artery. This was associated with an occluded celiac axis. Due to the unusually large proximal and distal landing zones, a covered balloon-expandable stent was deployable with the successful exclusion of the aneurysm. This is the first reported case report of successful management of retroperitoneal rupture and associated pancreaticoduodenal aneurysm treated with a covered stent graft. This technique allowed for rapid access and exclusion of the aneurysm. In addition, it allowed the preservation of foregut flow through the collateral pathway and successfully excluded the large aneurysm.
