Celiacomesenteric trunk: a variation that must be known before aortic surgery

Successful endovascular treatment of chronic mesenteric ischemia in a patient with variant celiacomesenteric trunk anatomy

The celiacomesenteric trunk (CMT) is a rare anatomical variant where the celiac axis and superior mesenteric artery share a common origin. Despite its rarity, CMT has significant implications across various medical fields, particularly in surgical planning and interventional procedures. We report a case of chronic mesenteric ischemia owing to atherosclerotic stenosis at the CMT bifurcation, necessitating a complex interventional approach. Kissing covered stent angioplasty was successfully performed, resulting in revascularization, symptom resolution, and no restenosis at 1-year follow-up. This report highlights the feasibility and effectiveness of the kissing stent technique in managing complex CMT bifurcation obstructions in patients with chronic mesenteric ischemia.

Important Variations of Aortic Branches: Imaging Case Series

Various anatomical variations are known to occur in branches of the aorta. Some of these variations are common while others are quite uncommon. However, these variations carry significant implications when the patient is diseased and some intervention or surgical procedure is to be done. Most of these variations are usually incidentally detected. This imaging case series illustrates some clinically important variations of aortic branches including branches of the aortic arch and abdominal aorta, with a review of the literature. All cases illustrated here were detected incidentally.

Diagnostic and Surgical Implications of Non-occlusive Mesenteric Ischemic Ileus Associated With Common Celiacomesenteric Trunk: A Case Report and Literature Review

The celiacomesenteric trunk (CMT), an exceedingly rare anatomic variant uniting the celiac artery and superior mesenteric artery (SMA), holds significant clinical and surgical implications. Despite its rarity, understanding these implications is crucial for effective management. This report outlines the case of a 99-year-old female presenting with septic shock and abdominal pain, with imaging revealing an incidental CMT. This paper aims to elucidate the surgical implications associated with CMT through a comprehensive case review and literature search. A 99-year-old female with multiple cardiovascular comorbidities presented with altered mental status and right lower quadrant abdominal pain. Upon arrival, the patient exhibited disorientation, an inability to follow commands, hypoxia, and hypotension. Significant laboratory findings included a white count of 20.6 x 109/L, lactate of 6.1 mmol/L, glucose of 53 mg/dL, alanine transaminase (ALT)/aspartate aminotransferase (AST) of 186/336 U/L, and creatinine of 4.2 mg/dL. Immediate interventions involved high-flow oxygen, fluid resuscitation, intravenous antibiotics, and admission to the ICU for septic shock. A CT angiogram (CTA) revealed an incidental large common trunk comprising the celiac trunk and superior mesenteric artery (SMA). There was a high-grade stenosis at the origin of the SMA. However, all the vessels were widely patent distally, and acute mesenteric occlusion was ruled out. By day 12, the patient achieved clinical stability after conservative management and was discharged. Complications such as aneurysm, dissection, stenosis, thrombosis, or acute occlusion of a CMT may necessitate complex surgical interventions, including endovascular procedures or open hepatic surgery. Understanding these technical complexities is vital for avoiding surgical complications in critically ill patients.

A rare case of unconnection between the celiac trunk and the abdominal aorta and a large anastomosis with the inferior mesenteric artery with a literature review

PURPOSE

Direct connection between the celiac trunk (CT) and inferior mesenteric artery (IMA) is very rare, knowledge of this anomaly is of great importance to surgeons and anatomists.

INTRODUCTION

Splanchnic arteries arise from the abdominal aorta (AA). Unusual development of these arteries can lead to considerable variations. Historically there were a lot of classification of the variation in the CT and IMA, none of the classifications describes a direct connection from IMA to CT.

MATERIALS AND METHODS

We report a rare case in which the connection between the CT and AA was lost and replaced by a direct anastomosis with IMA.

RESULTS

60 year old male presented to the hospital to undergo a computed tomography scan. Which showed that there was no CT arising from the AA, but there was a large anastomosis arises from the IMA and ended with a short axis and Left gastric artery (LGA), Splenic artery (SA), Common hepatic artery (CHA) arise from this axis, these arteries continued to the stomach and spleen and liver normally. The anastomosis provides the total supply to the CT. The CT branches are normal.

CONCLUSION

Knowledge of the arterial anomalies provides an important help in clinical surgical implications especially in organs transplant.

Spontaneous celiacomesenteric trunk dissection: Case report

INTRODUCTION

The celiacomesenteric trunk (CMT) is one of the most striking among the different variations of the normal vascularisation of the gastro-intestinal tract. It is often accidentally discovered during autoptical dissections, angiography or abdominal computed tomography (CT).

CASE PRESENTATION

A 27-year-old man was admitted to emergency for an acute abdominal pain. For his critical condition, the patient was immediately brought to the operating room. A extensive intestinal necrosis was found. Post-operator CT discovered a common CMT that is complicated by extended thrombosis. Despite all resuscitation measures, the patient died of septic shock two days later. An autopsy was performed showed that the main cause of intestinal ischemia was related to dissection of a common CMT.

DISCUSSION

A CMT is a highly unusual variation in humans. It is usually asymptomatic and may be discovered incidentally during vascular surgery, radiologic imaging, or cadaver's dissection. Lesion of this entity can lead to serious gastrointestinal complications including necrosis. Different classifications are proposed in the literature.

CONCLUSION

As it is associated with the risk of mesenteric ischaemia, CMT should be kept in mind as a differential diagnosis for cases of recurrent non-specific abdominal pain.

Recurrent Mesenteric Ischemia from Celiomesenteric Trunk Stenosis

A common origin of the celiac trunk and superior mesenteric artery (SMA), also termed as celiomesenteric trunk (CMT), is a rare occurrence. We report a rare case of symptomatic CMT stenosis requiring multiple interventions. The patient underwent an initial superior mesenteric artery bypass graft but required a subsequent endoluminal intervention. We present this case for the rarity of CMT stenosis and its potential to cause recurrent mesenteric ischemia. The treatment outcome in this patient suggests that revascularization of the SMA alone can result in adequate perfusion of the entire mesenteric bed and resolve symptoms of mesenteric ischemia including weight loss and food avoidance.
