Understanding Superior Mesenteric Artery Syndrome: Etiology, Symptoms, Diagnosis, and Management.

Superior mesenteric artery (SMA) syndrome, also known as Wilkie's syndrome, poses a diagnostic challenge due to its rarity and varied clinical manifestations. This review explores the syndrome's etiology, symptoms, diagnostic challenges, and management strategies. Symptoms range from early satiety to severe abdominal pain, often leading to malnutrition. Diagnosis involves a thorough gastrointestinal evaluation and various imaging modalities. Management includes medical interventions like nasogastric decompression and nutritional support, along with surgical interventions such as duodenojejunostomy. A thorough understanding of SMA syndrome's complexities is crucial for its timely diagnosis and effective management, especially considering its potential overlap with other gastrointestinal disorders or eating disorders. Further research is needed to enhance understanding and improve patient outcomes.

A unique posterior nutcracker syndrome combined with Wilkie syndrome: A singular case.

Left renal vein variants are not commonly observed in the general population. Usually, the renal vein runs in front of the aorta before entering the inferior vena cava, while the most common variants include the presence of a circumaortic or retroaortic renal vein. However, when present, left venal rein variants are important to recognize due to their potential clinical and surgical relevance. In this regard, CE-CT is an instrument with high sensitivity and specificity in detecting vascular anomalies and can certainly help diagnose. In this article, we present a unique case of a left venal rein compressed between the left iliac artery and vertebral bodies associated with the presence of a superior mesenteric artery Syndrome, another rare entity that occurs when the duodenum is compressed between the aorta and the superior mesenteric artery.

No-touch isolation technique in emergency pancreaticoduodenectomy for neoplastic hemorrhage: Two case reports and review of literature.

BACKGROUND: Emergency pancreaticoduodenectomy (EPD) is a rare event for complex periampullary etiology. Increased intraoperative blood loss is correlated with poor postoperative outcomes. CASE SUMMARY: Two patients underwent EPD using a no-touch isolation technique, in which all arteries supplying the pancreatic head region were ligated and divided before manipulation of the pancreatic head and duodenum. The operative times were 220 and 239 min, and the blood loss was 70 and 270 g, respectively. The patients were discharged on the 14th and 10th postoperative day, respectively. Thirty-two patients underwent EPD for the treatment of neoplastic bleeding. The mean operative time was 361.6 min, and the mean blood loss was 747.3 g. The complication rate was 37.5%. The in-hospital mortality rate was 9.38%. CONCLUSION: The no-touch isolation technique is feasible, safe, and effective for reducing intraoperative blood loss in EPD.

Emergency rescue of a patient with hemorrhagic shock caused by superior mesenteric artery rupture: A case report.

BACKGROUND: Superior mesenteric artery (SMA) injuries rarely occur during blunt abdominal injuries, with an incidence of < 1%. The clinical manifestations mainly include abdominal hemorrhage and peritoneal irritation, which progress rapidly and are easily misdiagnosed. Quick and accurate diagnosis and timely effective treatment are greatly significant in managing emergent cases. This report describes emergency rescue by a multidisciplinary team of a patient with hemorrhagic shock caused by SMA rupture. CASE SUMMARY: A 55-year-old man with hemorrhagic shock presented with SMA rupture. On admission, he showed extremely unstable vital signs and was unconscious with a laceration on his head, heart rate of 143 beats/min, shallow and fast breathing (frequency > 35 beats/min), and blood pressure as low as 20/10 mmHg (1 mmHg = 0.133 kPa). Computed tomography revealed abdominal and pelvic hematocele effusion, suggesting active bleeding. The patient was suspected of partial rupture of the distal SMA branch. The patient underwent emergency mesenteric artery ligation, scalp suture, and liver laceration closure. In view of conditions with acute onset, rapid progression, and high bleeding volume, key points of nursing were conducted, including activating emergency protocol, opening of the green channel, and arranging relevant examinations with various medical staff for quick diagnosis. The seamless collaboration of the multidisciplinary team helped shorten the preoperative preparation time. Emergency laparotomy exploration and mesenteric artery ligation were performed to mitigate hemorrhagic shock while establishing efficient venous accesses and closely monitoring the patient's condition to ensure hemodynamic stability. Strict measures were taken to avoid intraoperative hypothermia and infection. CONCLUSION: After 3.5 h of emergency rescue and medical care, bleeding was successfully controlled, and the patient's condition was stabilized. Subsequently, the patient was transferred to the intensive care unit for continuous monitoring and treatment. On the sixth day, the patient was weaned off the ventilator, extubated, and relocated to a specialized ward. Through diligent medical intervention and attentive nursing, the patient made a full recovery and was discharged on day 22. The follow-up visit confirmed the patient's successful recovery.

Superior Mesenteric Artery Thrombosis in COVID-19-Positive Patients: A Rare Coincidence.

Since the start of the SARS-CoV-2 pandemic, which is otherwise known as the worldwide coronavirus disease, 2019, has had a well-established pro-thrombotic character. Patients often first exhibit respiratory symptoms, and those whose severity increases eventually develop acute hypoxic respiratory failure. The systemic hypercoagulable condition and arterial/venous thrombosis related to COVID-19 have a poor prognosis. Even though superior mesenteric artery (SMA) thrombosis and acute mesenteric ischemia (AMI) are uncommon, they frequently coexist with fatal gastrointestinal (GI) pathologies that necessitate prompt diagnosis and treatment by the doctor. This calls for more research into the effects of anticoagulation therapy in COVID-19-positive patients. The main treatment aims for this condition are early detection, surgical or intravascular re-establishment of blood supply to the ischemic bowel, and surgical resection. The study aimed to see the outcome after surgical intervention in patients with SMA thrombosis post-COVID-19 infection. This study was from March 2021 to January 2022, with a sample size of 5 patients with SMA thrombosis, which was confirmed on contrast-enhanced computed tomography (CECT) abdomen and pelvis with angiography. The patients underwent exploratory laparotomy. Bowel resection and anastomosis were performed in three individuals; bowel resection and stoma placement were performed in two patients. Doctors have significant clinical challenges as a result of the thromboembolic manifestations of the unexpected and deadly nature of the virus, such as AMI. The high morbidity and mortality associated with AMI calls for further study on prophylactic anticoagulation therapy in COVID-19-positive individuals.

Systematic review and meta-analysis of current evidences in endograft therapy vs. medical treatment for Spontaneous Isolated Superior Mesenteric Artery Dissection.

OBJECTIVE: Endovascular stent therapy (EST) for spontaneous isolated superior mesenteric artery dissection (SISMAD) is gaining popularity, yet the treatment strategy - BMT or EST - remains debatable. METHODS: A meta-analysis examined all randomized trials and observational studies exploring the relative merits and potential risks of EST vs. BMT in treating SISMAD patients. Key outcomes included early and long-term adverse effects, with odds ratios (ORs) and 95% confidence intervals (CI) calculated. A random- or fixed-effects model was selected according to a 50% heterogeneity threshold. RESULTS: 9 observational studies involving a total of 672 SISMAD patients (303 EST), met our selection criteria. We discovered no noteworthy distinctions between the EST group and the BMT group in terms of early symptoms' alleviation, reinterventions, or all-cause mortality. However, patients receiving EST management will be hospitalized longer than those receiving BMT (EST: 13.2 ± 5.1 months vs. BMT: 7.0 ± 2.2 months, P < 0.01). In the long run, EST was found to significantly contribute to a higher rate of complete remodeling (OR: 4.53, CI: 3.01 ~ 6.81, P < 0.01; heterogeneity, I2 = 50%) and a lower incidence of aneurysm formation (OR: 0.19, CI: 0.06 ~ 0.6, P < 0.01; heterogeneity, I2 = 0%) than BMT. However, there are no significant differences between ESTand BMTin terms of all-cause mortality, recurrent syndrome, reintervention, and SMA stenosis or occlusion. CONCLUSION: EST can effectively prevent the formation of aneurysmal dissection and improve SISMAD remodeling. Both EST and BMT are similar in reducing long-term mortality, recurrent symptoms, severe SMA stenosis or occlusion, and the need for reintervention in patients with SISMAD.

A rare cause of upper gastrointestinal system obstruction: Superior mesenteric artery syndrome (Wilkie's syndrome); two different case reports.

Superior mesenteric artery syndrome is defined as a collection of clinical symptoms and findings that result from compression of the third part of the duodenum between the aorta and the superior mesenteric artery. Here, we describe two patients who were diagnosed with superior mesenteric artery syndrome. Two patients, 18 and 38 years old, respectively, presented to our clinic with complaints of nausea, vomiting, and weight loss. Computed tomography scans of both patients supported diagnoses of superior mesenteric artery syndrome. The 18-year-old patient recovered with conservative treatment. However, our 38-year-old patient did not recover with conservative treatment and required two surgeries. In the first operation, duodenal release with Treitz's ligament dissection and pyloroplasty were performed because of concomitant hypertrophic pyloric stenosis. Because the patient exhibited gastroparesis and gastric ptosis after the first operation, subtotal gastrectomy and Roux-n-Y gastrojejunostomy were performed in the second operation. No complications were observed during follow-up after the second operation. Superior mesenteric artery syndrome should be considered in the differential diagnosis of patients with nausea, vomiting, and weight loss of unknown cause. During treatment, weight-gaining conservative approaches should be attempted initially, but surgical treatment should not be excessively delayed in patients who do not respond to medical treatment.

Clinical characteristics and impact of pseudo-lumen blood flow on long-term vessel dilatation in spontaneous isolated dissection of superior mesenteric/celiac artery.

This study aimed to identify the clinical characteristics associated with spontaneous isolated dissection of superior mesenteric artery/celiac artery (SIDSMA/SIDCA). This observational study, conducted at Toranomon Hospital, Japan between 2009 and 2020, analyzed consecutive SIDSMA/SIDCA cases based on radiology data. The study compared clinical characteristics between symptomatic and asymptomatic patients with SIDSMA/SIDCA and investigated factors related to future vessel dilatation. Among 57 cases (44 SIDSMA, 17 SIDCA, and 4 both), the majority were male (87.7%), nearly half having hypertension (43.9%) and smokers (48.9%). Of those, 17 cases (29.8%) were symptomatic; abdominal pain (94.1%), back pain (23.5%), nausea (17.6%) and fever (5.9%). The symptomatic group was younger (52.6 ± 9.4 versus 67.2 ± 7.9 years, P < 0.001), had higher systolic and mean blood pressure (142.6 ± 20.0 versus 129.5 ± 16.5 mmHg, P = 0.017; 96.1 ± 14.6 versus 88.2 ± 17.7 mmHg, P = 0.038), a higher white blood cell count (9975 ± 5032 versus 6268 ± 1991 /µL, P = 0.012), and a higher LDL cholesterol level at diagnosis (129.7 ± 21.7 versus 87.2 ± 25.6 mg/dL, P = 0.002) than the asymptomatic group. The factors associated with future vessel dilatation included the presence of pseudo-lumen flow in the dissection vessel (73.9% versus 41.4%, p = 0.019) and a larger vessel diameter (13.5 ± 2.4 mm versus 11.5 ± 2.1 mm, p = 0.005) at diagnosis after multiple adjustments, pseudo-lumen flow was a predictor of future vessel dilatation (odds ratio, 4.80; 95% confidence interval, 1.11-20.75; p = 0.036). The study revealed that only 30% of SIDSMA/SIDCA cases were symptomatic. Symptomatic cases were generally younger and exhibited higher blood pressure and elevated white blood cell counts. These findings offer valuable insights for the acute diagnosis of SIDSMA/SIDCA.

Investigation of abdominal artery delineation by photon-counting detector CT.

OBJECTIVES: To evaluate the ability of 50-keV virtual monoenergetic images (VMI) to depict abdominal arteries in abdominal CT angiography (CTA) compared with 70-keV VMI with photon-counting detector CT (PCD-CT). METHODS: Fifty consecutive patients who underwent multiphase abdominal scans between March and April 2023 were included. Signal-to-noise ratio (SNR) and contrast-to-noise ratio (CNR) were quantitatively assessed for the abdominal aorta (AA), celiac artery (CeA), superior mesenteric artery (SMA), renal artery (RA), and right hepatic artery (RHA) at both 50- and 70-keV VMI. In addition, 3D images from CTA were analyzed to measure arterial lengths and evaluate the visualization of distal branches. RESULTS: Significantly higher SNR and CNR were observed at 50-keV compared to 70-keV VMI for all arteries: AA (36.54 and 48.28 vs. 25.70 and 28.46), CeA (22.39 and 48.38 vs. 19.09 and 29.15), SMA (23.34 and 49.34 vs. 19.67 and 29.71), RA (22.88 and 48.84 vs. 20.15 and 29.41), and RHA (14.38 and 44.41 vs. 13.45 and 27.18), all p < 0.05. Arterial lengths were also significantly longer at 50-keV: RHA (192.6 vs. 180.3 mm), SMA (230.9 vs. 216.5 mm), and RA (95.9 vs. 92.0 mm), all p < 0.001. CONCLUSION: In abdominal CTA with PCD-CT, 50-keV VMI demonstrated superior quantitative image quality compared to 70-keV VMI. In addition, 50-keV VMI 3D CTA allowed better visualization of abdominal artery branches, highlighting its potential clinical advantage for improved imaging and detailed assessment of abdominal arteries.

Association between underweight status or low body mass index and the risk of developing superior mesenteric artery syndrome following scoliosis corrective surgery in pediatric patients: a review of the literature.

Superior mesenteric artery (SMA) syndrome is the compression of the third portion of the duodenum between the abdominal aorta and the superior mesenteric artery. Although multifactorial, the most frequent cause of SMA syndrome is significant weight loss and cachexia often induced by catabolic stress. SMA syndrome resulting from scoliosis surgery is caused by a reduction of the aortomesenteric angle and distance. Risk factors include rapid weight loss, malnutrition, and a rapid reduction in the mesenteric fat pad and are the most common causes of a decrease in the aortomesenteric angle and distance. Surgically lengthening the vertebral column can also lead to a reduction of the aortomesenteric distance, therefore, has been identified as a risk factor unique to spinal surgery. Despite a reported decline in SMA syndrome cases due to improved surgical techniques, duodenal compression is still a risk and remains a life-threatening complication of scoliosis surgery. This article is a cumulative review of the evidence of being underweight or having a low body mass index as risk factors for developing SMA syndrome following surgical scoliosis instrumentation and correction.

Superior Mesenteric Artery Mycotic Pseudoaneurysm Following Infective Endocarditis in a Patient With Rheumatic Heart Disease: A Case Report.

We present a rare case of a 25-year-old woman with rheumatic heart disease who developed a superior mesenteric artery pseudoaneurysm (SMAPA) following infective endocarditis (IE). Initially, she presented with chest pain, dyspnea, and fever, leading to the diagnosis of IE and severe mitral regurgitation. After six weeks of antimicrobial therapy, she developed persistent abdominal pain. Further evaluation revealed a mycotic SMAPA, which was successfully treated with open surgical repair. Postoperatively, her abdominal pain improved significantly, and she was discharged on postoperative day five. The current case underscores the importance of maintaining a high index of suspicion for mycotic pseudoaneurysms in patients with risk factors, even when they present with nonspecific symptoms. The findings also highlight the critical role of computed tomography angiography (CTA) in accurate diagnosis and preoperative planning. The favorable outcome supports current guidelines for managing mycotic SMA pseudoaneurysms in complex scenarios, emphasizing the need for adherence to established protocols and recommendations.

Necrotic mega-stomach from superior mesenteric artery syndrome.

Superior mesenteric artery (SMA) syndrome is a rare cause of proximal bowel obstruction due to duodenal compression by the SMA. The morbidity and mortality associated with delayed diagnosis and its complications make it an important differential cause for bowel obstruction. We report a case of mega-stomach secondary to SMA syndrome requiring total gastrectomy. An 18-year-old male presented with vomiting, abdominal pain and shock after a buffet. Computed tomography (CT) imaging revealed a grossly distended stomach (113 × 187 × 350mm) and a transition point at the third part of the duodenum, along with pneumatosis and portal venous gas. Emergency gastroscopy showed blood and necrotic mucosa. Laparotomy confirmed full thickness necrosis and the patient underwent a total gastrectomy with Roux-en-Y reconstruction. Postoperatively, he had a brief intensive care stay and recovered without complications. This case underscores the importance of considering SMA syndrome during presentations of acute gastric dilatation.

Secondary Hemorrhagic Shock Due to Spontaneous Isolated Dissection of the Superior Mesenteric Artery Branch.

Spontaneous isolated dissection of the superior mesenteric artery (SIDSMA) is a rare condition, particularly when complicated by hemorrhagic shock. This case report describes the discovery of SIDSMA in an 88-year-old woman through CT angiography. The patient initially presented with acute abdominal pain, nausea, and diarrhea, which later progressed to hemorrhagic shock. After fluid resuscitation, the patient underwent successful endovascular treatment.

Unusual causes of Small bowel obstruction: a review of the literature and revisited cross-sectional imaging checklist.

Intestinal obstruction is a common surgical emergency with high morbidity and mortality. Patients presenting with features of small bowel obstruction need urgent evaluation to avoid complications such as bowel gangrene, perforation, or peritonitis. Imaging is necessary in most cases of suspected bowel obstruction, to take an appropriate decision, for apt patient management. Among the common causes of small bowel obstruction, adhesions, external herniae, malignancies, and Crohn's disease top the chart. Imaging helps in determining the presence of obstruction, the severity of obstruction, transition point, cause of obstruction, and associated complications such as strangulation, bowel gangrene, and peritonitis. This review is based on the cases with unusual causes of bowel obstruction encountered during our routine practice and also on the extensive literature search through the standard textbooks and electronic databases. Through this review we want our readers to have sound knowledge of the imaging characteristics of the uncommon yet important causes of bowel obstruction. We have also revisited and structured a checklist to simplify the approach while reporting a suspected case of small bowel obstruction. Imaging plays a key role in the diagnosis of small bowel obstruction and in determining the cause and associated complications. Apart from the common causes of small bowel obstruction, we should also be aware of the uncommon causes of small bowel obstruction and their imaging characteristics to make an accurate diagnosis and for apt patient management.

Totally thoracoscopic atrial fibrillation surgery following massive small bowel resection due to superior mesenteric artery embolization: report of two cases.

BACKGROUND: Thromboembolic occlusion of the superior mesenteric artery (SMA) is a grave complication in individuals diagnosed with atrial fibrillation (AF). This condition often necessitates extensive bowel resection, culminating in short bowel syndrome, which presents challenges for anticoagulant administration and/or antiarrhythmic therapy. CASE PRESENTATION: Presented here are findings of two patients, aged 78 and 72 years, respectively, who underwent comprehensive thoracoscopic AF surgery subsequent to extensive small bowel resection following SMA embolization. In each, onset of AF precipitated an embolic event, while the concurrent presence of short bowel syndrome complicated anticoagulation management. Total thoracoscopic AF surgery, comprised stapler-closure of the left atrial appendage (LAA) and bilateral epicardial clamp-isolation of the pulmonary veins, an operative modality aimed at addressing AF rhythm control and mitigating embolic events such as cerebral infarction, led to favorable outcomes in both cases. Additionally, computed tomography (CT) conducted one month post-surgery revealed the absence of residual tissue in the LAA, with the left atrium demonstrating a well-rounded, spherical shape. At the time of writing, the patients have remained asymptomatic following surgery regarding thromboembolic and arrhythmic manifestations for 29 and 10 months, respectively, notwithstanding the absence of anticoagulant or antiarrhythmic pharmacotherapy. Additionally, electrocardiographic surveillance has revealed persistent sinus rhythm. CONCLUSIONS: The present findings underscore the feasibility and efficacy of a total thoracoscopic AF surgery procedure for patients presented with short bowel syndrome complicating SMA embolization, thus warranting consideration for its broader clinical application.

Unusual neonatal case of superior mesenteric artery syndrome with Meckel's diverticulum and literature review.

Superior mesenteric artery syndrome (SMAS) is a rare cause of duodenal obstruction which is characterized by compression of the duodenum due to narrowing of the space between the superior mesenteric artery and aorta. Incomplete duodenal obstruction due to SMAS in neonates is rarely reported in the literature. In this case, it is a full-term 2-day-old male with the complaint of recurrent vomiting starting soon after birth. The patient was diagnosed with SMAS and duodenoduodenostomy was performed. Accompanying Meckel's diverticulum was excised.

El síndrome de la arteria mesentérica superior (SMAS) es una causa rara de obstrucción duodenal que se caracteriza por la compresión del duodeno debido al estrechamiento del espacio entre la arteria mesentérica superior y la aorta. La obstrucción duodenal incompleta por SMAS en recién nacidos rara vez se informa en la literatura. En este caso se trata de un varón de 2 días nacido a término que presenta vómitos recurrentes desde poco después del nacimiento. El paciente fue diagnosticado de SMAS y se le realizó duodenoduodenostomía. Se extirpó el divertículo de Meckel que lo acompañaba.

Comparison of Endovascular Therapy and Open Surgical Revascularization in Patients With Acute Superior Mesenteric Artery Occlusion: A Large-Scale Analysis Based on the JROAD-DPC Database.

BACKGROUND: Acute mesenteric ischemia is rare, and few large-scale trials have evaluated endovascular therapy (EVT) and open surgical revascularization (OS). This study aimed to assess clinical outcomes after EVT or OS for acute superior mesenteric artery occlusion and identify predictors of mortality and bowel resection. METHODS AND RESULTS: Data from the Japanese Registry of All Cardiac and Vascular Diseases-Diagnosis Procedure Combination (JROAD-DPC) database from April 2012 to March 2020 were retrospectively analyzed. Overall, 746 patients with acute superior mesenteric artery occlusion who underwent revascularization were classified into 2 groups: EVT (n=475) or OS (n=271). The primary clinical outcome was in-hospital mortality. The secondary outcomes were bowel resection, bleeding complications (transfusion or endoscopic hemostasis), major adverse cardiovascular events, hospitalization duration, and cost. The in-hospital death or bowel resection rate was ≈30%. In-hospital mortality (22.5% versus 21.4%, P=0.72), bowel resection (8.2% versus 8.5%, P=0.90), and major adverse cardiovascular events (11.6% versus 9.2%, P=0.32) were comparable between the EVT and OS groups. Hospitalization duration in the EVT group was 6 days shorter than that in the OS group, and total hospitalization cost was 0.88 million yen lower. Interaction analyses revealed that EVT and OS had no significant difference in terms of in-hospital death in patients with thromboembolic and atherothrombotic characteristics. Advanced age, decreased activities of daily living, chronic kidney disease, and old myocardial infarction were significant predictive factors for in-hospital mortality. Diabetes was a predictor of bowel resection after revascularization. CONCLUSIONS: EVT was comparable to OS in terms of clinical outcomes in patients with acute superior mesenteric artery occlusion. Some predictive factors for mortality or bowel resection were obtained. REGISTRATION: URL: www.umin.ac.jp/ctr/; Unique Identifier: UMIN000045240.

A case of contained rupture of the superior mesenteric artery with no distal flow causing mesenteric ischemia following double heart valve replacement surgery.

A visceral artery aneurysm (VAA) is a very rare and lethal vascular anomaly with dramatic consequences. The overall incidence of VAA is 5% of all abdominal artery aneurysms. The involvement of the superior mesenteric artery is even rare (incidence of 3.5-8% of all VAA). The development of superior mesenteric artery pseudoaneurysm following cardiac surgery is scarcely reported in the literature. We report a case of contained rupture of the superior mesenteric artery with no distal flow causing acute mesenteric ischemia (AMI) following double heart valve replacement surgery.

Variations in origin level of superior mesenteric artery, inferior mesenteric artery and coeliac trunk in indian population.

OBJECTIVE: The abdominal aorta is a continuation of the thoracic aorta and gives off coeliac trunk, superior mesenteric artery & inferior mesenteric artery. The focus of our study is to evaluate variations in origin level in coeliac trunk, Superior Mesenteric artery, Inferior Mesenteric artery, and Aortic bifurcation in the Indian population and compare with various demographics. MATERIALS AND METHODS: The study was retrospective and the local ethics committee approval was taken before starting it. 300 patients who were of more than 18 years of age and required CECT studies were included in this. The vertebral origin level of the arteries from Abdominal Aorta and Aortic Bifurcation level was analyzed. RESULTS: The most common origin level of Coeliac trunk for both males and females was T12-L1 Disc level. The most common origin level of Superior Mesenteric Artery was L1 Upper level. The most common origin level of Inferior Mesenteric Artery was L3 Upper level. The most common origin level of Superior Mesenteric Artery was L5 Lower level. There was no statistical difference between the origin of any arteries in Males and Females in the Indian Population. CONCLUSION: As per our study in the Indian population and the published literature it is realized that there are significant variations in origins of Coeliac Trunk, Superior Mesenteric artery, Inferior Mesenteric artery and Abdominal Aorta bifurcation in different populations. ADVANCES IN KNOWLEDGE: This study elaborates on potential Anatomical Variations in Indian Population, particularly Mumbai City population. Also, our study compares it to different countries' data and their results in variations found in Abdominal Aorta branches.
