Feasibility and safety of robotic-assisted surgical approach in median arcuate ligament syndrome-a systematic review.

Median arcuate ligament syndrome (MALS) is rare syndrome and is diagnosis of exclusion. Though first robotic median arcuate ligament release (MALR) was described in 2007, there are only a few case reports (CR), case series (CS), and retrospective cohort studies (RCS) in the published literature. The purpose of this study was to assess the feasibility and safety of robotic-assisted MALR (r-MALR). PubMed, Embase, and Cochrane databases were searched (last search December 2023) for articles reporting r-MALR. All studies including CR, CS, RCS reporting technical feasibility (operating time and rate of conversions), safety (intra-operative complications, blood loss, post-operative complications), and outcome (length of stay [LoS]) were included (PROSPERO: CRD42024502792). A total of 23 studies (8-CR, 5-CS, 10-RCS) with total 290 patients were available in the literature. Except 1-RCS, all studies reported age and mean age for CR was 40.38 ± 17.7, 36.08 ± 15.12 for CS, 39.72 ± 7.35 years for RS; except 2-RCS, all studies reported gender distribution and there were 57 males and 214 females. Operating time: 3-CR, 4-CS, 9-RCS reported operating time, and mean time was 111 ± 54, 131.69 ± 7.51, 117.34 ± 35.03 min, respectively. Conversion rate: All studies reported data on conversion and only four (1.37%) cases were converted-one to laparoscopic approach, three to open approach (1-inadvertent celiac arteriotomy, 2-reasons not mentioned). Intraoperative complications: only 5-CR, 4-CS, and 9-RCS reported data on intra-operative complications, and there were only 6 complications (1.5%): 1-inadvertent celiac arteriotomy converted to open; 3-unnamed vascular injuries (2 managed robotically, 1 converted to open); 1-bleeding managed robotically; there were no other reported injuries. Estimated blood loss ranged from 5 to 30 ml. Post-operative complications: 5-CR, 4-CS, 8-RCS described post-operative complications in 21 (7%) patients. Twenty cases were grade I, one was grade IIIa, and all managed successfully. LoS stay: 2-CR, 4-CS, 10-RCS reported LoS and overall, it was 2 days. r-MALR is reasonable, technically feasible, safe, and has acceptable outcomes. In addition, robotic approach provided superior vision, improved dexterity, precise, and easy circumferential dissection.PROSPERO registration: The protocol was registered in the PROSPERO database (CRD42024502792).

Recurrent myocardial infarction in a patient with median arcuate ligament syndrome: a case report and literature review.

Median arcuate ligament (MAL) syndrome, otherwise known as celiac artery compression syndrome, is rare and is characterized by celiac artery compression by the median arcuate ligament. We report a unique case of MAL syndrome with recurrent myocardial infarction as the primary manifestation, and offer new pathophysiological insights. A man in his early 50s experienced recurrent upper abdominal pain, electrocardiographic changes, and elevated troponin concentrations, which suggested myocardial infarction. Contrast-enhanced computed tomography showed considerable celiac artery stenosis due to MAL syndrome. The patient was diagnosed with MAL syndrome and acute myocardial infarction. He declined revascularization owing to economic constraints, and opted to have conservative treatment with Chinese herbal extracts and medications. He succumbed to sudden cardiac death during a subsequent abdominal pain episode. The findings from this case show that MAL syndrome can present with recurrent myocardial infarction rather than typical intestinal angina symptoms. The pathophysiological link may involve intestinal and cardiac ischemia. An accurate diagnosis and appropriate management of MAL syndrome require careful evaluation and investigation.

I saw the "hook" sign of median arcuate ligament syndrome.

The hook sign is a radiologic finding best appreciated on a sagittal view of the celiac artery with computed tomography (CT) that indicates compression of the celiac artery. It refers to the hooked-shape of the proximal celiac artery caused by extrinsic compression by the median arcuate ligament. When seen in a patient with concurrent abdominal symptoms, it suggests median arcuate ligament syndrome (MALS). We saw the sign in a 15-year-old male via duplex ultrasonography and abdominal CT. He underwent laparoscopic release of the median arcuate ligament and had full resolution of his symptoms at follow-up.

Clinical outcomes after surgical decompression of median arcuate ligament syndrome-An observational study.

BACKGROUND AND OBJECTIVES: Median arcuate ligament syndrome is caused by compression and stenosis of the celiac artery. Incision of the median arcuate ligament improves persistent abdominal symptoms. The study aimed at evaluating the outcomes in patients who underwent median arcuate ligament syndrome decompression using a self-report questionnaire. METHODS: This single-center retrospective study included patients with median arcuate ligament syndrome who underwent decompression surgery between April 2021 and February 2023. The medical records were retrospectively reviewed. RESULTS: Ten patients were included in the study. Laparotomy and laparoscopic surgeries were performed in seven and three patients, respectively. The median operation time was 147 minutes. The median hospitalization period after the operation was seven days. The degrees of celiac artery stenosis before and after surgery were compared and the per cent diameter stenosis did not significantly improve; five of 10 patients (50%) had > 50% stenosis in the celiac artery after the operation. Compared to the baseline, the scores of upper gastrointestinal symptoms significantly improved during the six months' period (p < 0.001). Additionally, we evaluated the influence of post-operative per cent diameter stenosis and divided the patients into two groups (≥ 50% vs, < 50%). The scores of upper gastrointestinal (GI) symptoms in both groups improved significantly from baseline. However, the symptomatic improvement at six months in the post-operative per cent diameter stenosis < 50% group was significantly greater than that in the ≥ 50% group (p = 0.016). The scores of lower gastrointestinal symptoms did not change significantly during the six-month period. CONCLUSION: Decompression surgery for median arcuate ligament syndrome could improve upper gastrointestinal symptoms regardless of the post-operative per cent diameter stenosis.

Displasia fibromuscular y síndrome de ligamento arcuato medio. Infrecuentesy simultáneos / Fibromuscular dysplasia and median arcuate ligament syndrome. Rare and simultaneous findings

Introducción: la displasia fibromuscular (DFM) es una patología poco frecuente de la capa muscular de las arterias. El síndrome de ligamento arcuato medio (SLAM) es una entidad infrecuente causada por la compresión extrínseca del tronco celíaco por el diafragma. Caso clínico: presentamos el caso de una mujer joven con DFM diagnosticada de afectación a nivel del tronco celíaco y de la arteria hepática común. Ante clínica de dolor abdominal, se solicita angio TC, que describe un SLAM asociado a la DFM. Se decide sección quirúrgica del ligamento arcuato y descompresión del tronco celíaco mediante abordaje robótico. Discusión: en ambas entidades la angiografía es el trataminto de referencia para el diagnóstico. El tratamiento de primera línea de la DFM es el endovascular mediante angioplastia, y del SLAM, el quirúrgico, seccionando el ligamento arcuato.(AU)

Introduction: fibromuscular dysplasia (FMD) is a rare disorder that affects the muscular layer of the arteries. The medianarcuate ligament syndrome (MALS) is also a rare disorder due to the extrinsic compression of the celiac trunk by thediaphragm.Case report: we report the case of a young woman with FMD and splachnic involvement of the celiac trunk and thecommon hepatic artery level. After presenting with abdominal pain, a CCTA was performed that revealed the presenceof FMD-related MALS. The surgical section of the arcuate ligament and decompression of celiac trunk were decided andperformed through robotic approach.Discussion: the gold standard for the diagnosis of both entities is angiography. However, while the first-line therapy ofFMD is endovascular, in the case MALS the best alternative is surgical treatment sectioning the arcuate ligament.(AU)

Exploring celiac trunk parameters in median arcuate ligament syndrome: A CT study.

PURPOSE: To assess anatomical variations in the celiac trunk (Ct) in patients with Median Arcuate Ligament Syndrome (MALS) using computed tomography (CT). The primary objectives were to investigate the celiac trunk angle (CtA), origin level, length (CtL), and their relationships with the superior mesenteric artery (SMA) in MALS patients. Additionally, the study intended to evaluate gender differences in these parameters and explore correlations between variables. METHODS: Retrospectively, reports of abdominal CT scans taken between January 2018, and Sepmtember 2021, in the hospital image archive were screened vey two observers independently for MALS diagnosis. Parameters such as CtA, CtL, Ct-SMA distance, SMA angle (SMAA), and median arcuate ligament thickness (MALT) were measured. Statistical analyses were conducted using SPSS software. RESULTS: Among the 81 patients (25 females, 56 males), significant differences were observed in MALT between genders (p = 0.001). CtA showed a negative correlation with CtL and Ct-SMA (p < 0.001), and a positive correlation was found between CtL and Ct-SMA (p = 0.002). CtL was measured as 25 mm for the all group. Origin levels of Ct and SMA were evaluated in comparison to vertebral levels. Ct-SMA distance was relatively shorter (9.19 mm) compared to the literature. SMAA findings were consistent with normal population values. CONCLUSION: This study provided valuable insights into the anatomical parameters of the Ct ans SMA in MALS patients. Despite some differences compared to normal population parameters, no evidence supported the hypothesis of a superiorly placed Ct contributing to MALS.

Vascular compression syndromes in the abdomen and pelvis: a concise pictorial review.

Vascular compression syndromes are a diverse group of pathologies that can manifest asymptomatically and incidentally in otherwise healthy individuals or symptomatically with a spectrum of presentations. Due to their relative rarity, these syndromes are often poorly understood and overlooked. Early identification of these syndromes can have a significant impact on subsequent clinical management. This pictorial review provides a concise summary of seven vascular compression syndromes within the abdomen and pelvis including median arcuate ligament (MAL) syndrome, superior mesenteric artery (SMA) syndrome, nutcracker syndrome (NCS), May-Thurner syndrome (MTS), ureteropelvic junction obstruction (UPJO), vascular compression of the ureter, and portal biliopathy. The demographics, pathophysiology, predisposing factors, and expected treatment for each compression syndrome are reviewed. Salient imaging features of each entity are illustrated through imaging examples using multiple modalities including ultrasound, fluoroscopy, CT, and MRI.

[A Case of Adenocarcinoma of Pancreatic Head of Liver Disfunction after Pancreaticoduodenectomy with Celiac Artery Stenosis Treated by Urgent Median Arcuate Ligament Release].

This patient visited our hospital for the purpose of detailed examination of prostate cancer in his seventies. Abdominal contrast-enhanced computed tomography(CT)revealed a low-density mass of 2 cm in the pancreatic head. He was diagnosed with pancreatic cancer. Pancreaticoduodenectomy was performed after 2 courses of gemcitabine and S-1 therapy were performed as neoadjuvant chemotherapy. An intraoperative clamp test of the gastroduodenal artery showed that the pulsation of the common hepatic artery and the proper hepatic artery was weak but sufficient, so the gastroduodenal artery was cut and the operation was completed as planned. A blood test on the 1st day after the operation showed elevated levels of AST 537 U/L, ALT 616 U/L, and 7 hours later blood sampling showed further increases in AST 1,455 U/L, ALT 1,314 U/L. After a detailed review of the preoperative CT, celiac artery stenosis due to compression of the arcuate ligament was suspected, and urgent median arcuate ligament release was performed on the same day. Dissection of the arcuate ligament significantly improved the pulsation of the common hepatic artery and proper hepatic artery. Postoperatively, hepatic enzymes improved and ISGPS showed Grade B pancreatic juice leakage, but the patient was discharged from the hospital on the 49th postoperative day without any other complications. He took S-1 as adjuvant chemotherapy, and no signs of recurrence have been observed 9 months after the operation.

Identical anatomy, different symptoms: a comparative case study of median arcuate ligament syndrome in monozygotic twins.

Median arcuate ligament syndrome (MALS) is a rare clinical entity arising from the extrinsic compression of the coeliac axis by the median arcuate ligament. In this report, we detail a unique presentation involving monozygotic twins, both of whom demonstrated anatomical extrinsic compression of the coeliac axis by the median arcuate ligament. Intriguingly, only one twin manifested clinical symptoms consistent with MALS, despite comparable anatomical compression of the coeliac axis observed in both. This case highlights the potential interplay of a genetic or anatomical predisposition to coeliac axis compression and secondary, possibly environmental, factors that lead to the development of clinical symptoms. In this report, we explore various determinants potentially influencing symptomatology in MALS and advocate for the publication of similar case studies to further elucidate this rare condition.

A radio-anatomical study of median arcuate ligament syndrome: unveiling the morphology and morphometry of median arcuate ligament, celiac trunk, and superior mesenteric artery.

PURPOSE: In the context of medical literature, a significant lacuna exists in understanding median arcuate ligament syndrome (MALS). While clinical aspects are well documented, literature lacks a robust exploration of the anatomical relationship between the celiac trunk and the median arcuate ligament (MAL). METHODS: Morphometric parameters, including the vertebral level of MAL origin, MAL thickness, celiac trunk (CeT) origin level, diameter, and distances between CeT/Superior Mesenteric Artery (SMA) and the MAL center were observed on 250 CT angiograms. Cadavers (n = 11) were dissected to examine the same parameters and histo-morphological examination of MAL tissue was done. RESULTS: Radiological findings established average MAL thickness of 7.79 ± 2.58 mm. The celiac trunk typically originated at T12. The average distance between the celiac trunk and the MAL center was 1.32 ± 2.04 mm. The angle of the celiac trunk to the abdominal aorta was primarily obtuse. The average celiac trunk diameter was 5.53 ± 1.33 mm. Histological examinations revealed a diverse MAL composition, indicating variable mechanical properties. CONCLUSION: This study provides comprehensive morphometric data on the anatomical relationship between the MAL and the celiac trunk. In contrast to available literature which says the average MAL thickness of > 4 mm is an indicator of increased thickness, we observed much higher average thickness in the studied population. The findings contribute to a better understanding of normal anatomical variations which can serve as reference values for accurate radiological diagnosis of MALS. The histological examination revealed the heterogeneous nature of the MAL tissue composition, suggesting variable mechanical properties and functions in different regions.

Intraoperative assessment of blood flow using transabdominal ultrasound during laparoscopic surgery of celiac artery compression syndrome.

Surgical treatment of celiac artery (CA) compression syndrome (CACS) is to release the median arcuate ligament (MAL) by removing the abdominal nerve plexus surrounding CA. In laparoscopic surgery of CACS, objective intraoperative assessment of blood flow in CA is highly desirable. We herein demonstrate a case of laparoscopic surgery of CACS with use of intraoperative transabdominal ultrasound. A 52-year-old woman was presented with epigastric pain and vomiting after eating. Contrast-enhanced computed tomography demonstrated significant stenosis at the origin of CA. Doppler study of CA was also performed, and she was diagnosed as CACS. Laparoscopic surgery was performed, and the MAL was divided. And then, Doppler study using intraoperative transabdominal ultrasound confirmed the successful decompression of CA. This patient was discharged on postoperative day 11, and her symptoms was improved. Intraoperative assessment of blood flow in CA using transabdominal ultrasound was a simple and useful method for laparoscopic surgery of CACS.

Median arcuate ligament release at the time of pancreaticoduodenectomy or total pancreatectomy.

BACKGROUND: Celiac artery compression can complicate the performance of pancreaticoduodenectomy or total pancreatectomy due to the need for ligation of the gastroduodenal artery. Median arcuate ligament release restores normal arterial flow to the liver, spleen, and stomach and may avoid complications related to poor perfusion of the foregut. METHODS: All patients who underwent median arcuate ligament release for celiac artery compression at the time of pancreatectomy between 2009 and 2023 were reviewed. Pre- and postoperative computed tomography was used to categorize celiac artery compression by the extent of compression (types A [<50%], B [50%-80%], and C [>80%]). RESULTS: Of 695 patients who underwent pancreatectomy, 22 (3%) had celiac artery compression, and a majority (17) were identified on preoperative imaging. Median celiac artery compression was 52% (interquartile range = 18); 8 (36%) patients had type A and 14 (64%) had type B compression with a median celiac artery compression of 39% (interquartile range = 18) and 59% (interquartile range = 14), respectively (P < .001). Postoperative imaging was available for 20 (90%) patients, and a reduction in the median celiac artery compression occurred in all patients: type A, 14%, and type B, 31%. Complications included 1 (5%) death after hospital discharge, 1 (5%) pancreatic fistula, 1 (5%) delayed gastric emptying, and 4 (18%) readmissions. No patient had evidence of a biliary leak or liver dysfunction. CONCLUSION: Preoperative computed tomography allows accurate identification of celiac artery compression. Ligation of the gastroduodenal artery during pancreaticoduodenectomy or total pancreatectomy in the setting of celiac artery compression requires median arcuate ligament release to restore normal arterial flow to the foregut and avoid preventable complications.

Clinical Outcomes after Median Arcuate Ligament Release in Patients Responsive to Celiac Plexus Block.

PURPOSE: To determine if symptom relief with celiac plexus block (CPB) is associated with favorable clinical outcomes after median arcuate ligament release (MALR) surgery. MATERIALS AND METHODS: A retrospective review was performed from January 2000 to December 2021. Fifty-seven patients (42 women, 15 men; mean age, 43 years [range, 18-84 years]) with clinical and radiographic features suggestive of median arcuate ligament syndrome (MALS) underwent computed tomography (CT)-guided percutaneous CPB for suspected MALS. Clinical outcomes of CPB and MALR surgery were correlated. Adverse events were classified according to the Society of Interventional Radiology (SIR) guidelines. RESULTS: CT-guided percutaneous CPB was successfully performed in all 57 (100%) patients with suspected MALS. A cohort of 38 (67%) patients showed clinical improvement with CPB. A subset of 28 (74%) patients in this group subsequently underwent open MALR surgery; 27 (96%) responders to CPB showed favorable clinical outcomes with surgery. There was 1 (4%) CPB-related mild adverse event. There were no moderate, severe, or life-threatening adverse events. CONCLUSIONS: Patients who responded to CPB were selected to undergo surgery, and 96% of them improved after surgery.

Laparoscopic Median Arcuate Ligament Release: Surgical Technique and Clinical Outcomes.

BACKGROUND: Median arcuate ligament syndrome (MALS) is characterized by a constellation of symptoms related to the compression of the celiac artery trunk. Laparoscopic release of the ligament has demonstrated its effectiveness in alleviating these symptoms while showing lower postoperative complication rates, reduced hospital stays, and improved clinical outcomes. This study describes a single institution's experience with this procedure and reports on the preoperative assessment, surgical technique, and clinical outcomes of patients with MALS. METHODS: We performed a retrospective chart review of all patients who underwent a primary laparoscopic MAL release (MALR) at a single high-volume academic institution from June 2021 to July 2023. Patient demographics, preoperative assessment, postoperative complications, and resolution of preoperative symptoms data were collected. RESULTS: A total of 30 patients underwent laparoscopic MALR, with 76.7% being female and a mean age of 33.4±16.3 years. The most common presenting symptom was postprandial epigastric pain (100%), followed by abdominal pain and nausea (83.3%), among others. The preoperative evaluation for all patients included a duplex mesenteric doppler and CT angiogram during inspiration and expiration and 3D reconstruction. Successful laparoscopic decompression of the celiac artery was achieved in 96.6% of cases, with only one conversion to an open procedure. There was only one reported early (<30 d postoperatively) complication with no subsequent late complications or mortality. None of the patients required reintervention or reoperation. Only 1 patient required postoperative celiac plexus/splanchnic block injection to alleviate pain. CONCLUSIONS: MALS can be effectively and safely managed using a laparoscopic approach when performed by an experienced minimally invasive surgeon. Further studies with longer follow-ups are needed to confirm the long-term effectiveness of this technique.

Characteristics and Trends in Median Arcuate Ligament Syndrome (MALS) Associated Visceral Artery Aneurysms: A Systematic Descriptive Review of the Literature.

Introduction: Median Arcuate Ligament Syndrome (MALS) is associated with true aneurysms, mainly of both the pancreaticoduodenal artery (PDA) and gastroduodenal artery (GDA). Although rare, their potential for rupture and adverse clinical outcomes warrants analysis. Prior studies suggest high rupture rates even for smaller aneurysms under 2 cm in this setting. We performed a systematic literature review, synthesising the evidence on visceral artery aneurysms related to MAL syndrome, with a focus on descriptive analyses of aneurysm size, presentation, rupture rates, and management. Methods: Literature search was performed using (Medline, EMBASE, Emcare and CINAHL). Inclusion criteria included true aneurysms secondary to MALS with or without rupture. The cases with pseudoaneurysms, concomitant pathologies eg, pancreatitis, conservatively managed aneurysms and articles with non-granular pooled data were excluded. Cases were assessed according to demographics, clinical presentation, aneurysm diameter, aneurysm rupture and management technique. Results: 39 articles describing 72 patients were identified. Aneurysm diameter in symptomatic patients was not significantly different from asymptomatic patients {21.0 and 22.3 mm respectively, P = .84}. Ruptured aneurysms were overall smaller than non-ruptured at presentation {12.3 mm v 30.8 mm respectively, P = .02}. Patients presented with abdominal pain (75.6%), nausea/vomiting (15.6%), hypotension (33.9%), shock (20.0%) and haemodynamic collapse (8.9%). 56.9% of all cases were managed with an endovascular approach, 19.4% were managed with an open surgical approach, and 23.6% were managed hybrid. Conclusion: This review suggests visceral artery aneurysms associated with median arcuate ligament rupture at variable sizes. Despite inability to clearly correlate size and rupture risk, our data supports prompt intervention irrespective of size, given the adverse outcomes. Further research is critically needed to clarify size thresholds or other predictors to guide management.

The anatomical relationship between the celiac artery and the median arch ligament in degenerative spinal surgery.

BACKGROUND: This study aimed to characterize the anatomical relationship between the spine, the celiac artery (CA), and the median arcuate ligament using preoperative contrast-enhanced computed tomography (CT) images of patients with spinal deformity who underwent surgical correction. METHODS: This retrospective study included 81 consecutive patients (34 males, 47 females; average age: 70.2 years). The spinal level at which the CA originated, the diameter, extent of stenosis, and calcification were determined using CT sagittal images. Patients were divided into two groups: CA stenosis group and non-stenosis group. Factors associated with stenosis were examined. RESULTS: CA stenosis was observed in 17 (21%) patients. CA stenosis group had significantly higher body mass index (24.9 ± 3.9 vs. 22.7 ± 3.7, p = 0.03). In the CA stenosis group, J-type CA (upward angling of the course by more than 90° immediately after descending) was more frequently observed (64.7% vs. 18.8%, p < 0.001). The CA stenosis group had lower pelvic tilt (18.6 ± 6.7 vs. 25.1 ± 9.9, p = 0.02) than non-stenosis group. CONCLUSIONS: High BMI, J-type, and shorter distance between CA and MAL were risk factors for CA stenosis in this study. Patients with high BMI undergoing fixation of multiple intervertebral corrective fusions at the thoracolumbar junction should undergo preoperative CT evaluation of the anatomy of CA to assess the poteitial risk of celiac artery compression syndrome.

Analysis of the relationship between spinal alignment and retrocrural space area in adult spinal deformity surgery: Potential risk factors for acute celiac artery compression syndrome.

PURPOSE: This study was designed to reveal the association between spinal parameters and RCS area in patients with adult spinal deformities treated with spinal correction surgery. We hypothesized that reduction of the retrocrural space (RCS) area is related to thoracolumbar alignment, which may cause acute celiac artery compression syndrome (ACACS). METHODS: Eighty-nine patients (age: 68.4 ± 7.6 years; sex: 7 male/82 female) with ASD treated by spinal correction surgery were enrolled. Preoperative and postoperative spinal parameters were measured, and the differences between these parameters were calculated. Postoperative T12 translation was measured and RCS area was evaluated using reconstructed computed tomography. The change of RCS area after surgery was defined as ΔRCS. Patients were divided into increased and decreased RCS groups by the ΔRCS value, and spinal parameters were compared between groups. The correlation between spinal parameters and ΔRCS was calculated. RESULTS: The patients in the decreased RCS group had greater anterior T12 translation than those in the increased RCS group (p < 0.001). T12 translation was significantly correlated with ΔRCS (ß = -0.31, p = 0.017). There were no correlations between ΔRCS and other spinal parameters. CONCLUSION: Thoracolumbar alignment was associated with RCS area. Consistent with the hypothesis, overcorrection of the thoracolumbar junction was associated with reduced RCS area and might be one risk factor for ACACS.

Celiac trunk thrombosis in a patient with antiphospholipid syndrome induced by median arcuate ligament compression: a case presentation and literature review.

Median arcuate ligament syndrome (MALS) is a rare disorder caused by the compression of the celiac axis by the fibrous structure of the diaphragm called the median arcuate ligament. Patients with MALS are usually undiagnosed unless characteristic symptoms such as nausea and vomiting, postprandial pain, and weight loss are presented. We report a case of a 29-year-old patient diagnosed with MALS and secondary antiphospholipid syndrome (APS) that developed celiac trunk, common hepatic artery and splenic artery thrombosis. There is not enough information on MALS as a trigger of thrombosis in predisposed patients such as those with APS. However, the case gives rise to suspicion and highlights the diagnostic processes, especially for patients with APS presenting postprandial abdominal pain and weight loss. This review likewise aims at the importance of Doppler ultrasonography as a screening tool and computer tomography (CT) or magnetic resonance (MR) both in the angiography variant, especially to diagnose confirmation and underlying treatment options.
