Gastrointestinal Function and Toxicology in Canines
Published in Shayne C. Gad, Toxicology of the Gastrointestinal Tract, 2018
The blood supply to the cervical portion of the esophagus is from small branches originating from the cranial and caudal thyroid arteries. The cranial two-thirds of the thoracic portion of the esophagus is supplied by the bronchoesophageal artery. The blood supply of the remaining portion of the thoracic esophagus comes from branches emanating from the dorsal intercostal arteries. The terminal portion of the esophagus receives its blood from a branch of the left gastric artery. The veins which drain the esophagus are basically a satellite vasculature of the arteries which supply it. However, veins which drain the thoracic portion of the esophagus for the most part empty into the azygous vein.

The blood supply to the stomach is derived from the celiac trunk. The greater curvature of the stomach is supplied by the right and left gastroepiploic arteries. The lesser curvature is supplied by the right and left gastric arteries. The right gastric artery and the right gastroepiploic artery are branches of the common hepatic artery and gastroduodenal artery, respectively. The left gastric artery is a branch of the celiac trunk, and the left gastroepiploic artery is a branch of the splenic artery. Routes of venous drainage include the gastric and gastroepiploic veins as well as small tributaries of the esophageal veins.
Open surgical management of visceral artery occlusive disease

The median arcuate ligament and interdigitating fibers of the crura are divided longitudinally to expose the aorta, which lies just posteriorly. A sufficient length of the supraceliac aorta is dissected and isolated along the anterior two-thirds of its circumference so that a side-biting clamp can be accommodated. The celiac ganglion that surrounds the celiac axis at its origin is divided. Dissection is continued caudally to the proximal few centimeters of the celiac axis (CA) (Figure 50.1). The inferior phrenic artery may be found in about 50% of cases and should be controlled. The left gastric artery is divided to facilitate end-to-end anastomosis to the CA. When an end-to-side anastomosis is chosen, the common or proper hepatic artery is chosen.
A rare complication of laparoscopic Roux-en-Y gastric bypass: case report of gastric remnant necrosis

Furthermore, compromised blood flow causing ischemia and necrosis of the gastric remnant may be due to surgical manipulation of the vessels. Ligation of part of the short gastric vessels and branches of the left gastric artery during LRYGB surgery to create the gastric pouch may contribute to vascular compromising of the gastric remnant [2,9]. In this case, vascular damage due to ligation of these vessels may explain the localization of the necrosis at the gastric remnant upper pole. Devascularisation of the gastric remnant from previous surgery might as well contribute to an increased risk of mesenteric ischemia, which in turn is a plausible cause of necrosis [5]. Apart from the LRYGB surgery three months before, the patient had a history of gastric banding. Injury of the left gastric artery caused by the gastric band may have contributed to vascular comprising of the gastric remnant upper pole in this case. Left gastric artery erosion was described previously in the light of gastric band erosion [10]. An association between previous gastric banding and gastric remnant necrosis post LRYGB was not yet described.

The patient was admitted and interventional radiology was consulted. Angiography with selection of the celiac axis revealed an irregular, beaded appearance of the left gastric artery (Figure 2a), characteristic of vasculitis. A small focus of active extravasation was also noted, and the left gastric artery was subsequently embolized utilizing Gelfoam and coils. The postembolization angiogram demonstrated no residual filling (Figure 2b). Following the procedure, the patient informed the care team that he recently underwent a temporal artery biopsy at an outside institution that confirmed GCA. He was prescribed daily prednisone and advised to follow-up with rheumatology. Following the procedure, his hemoglobin stabilized and he was discharged on hospital day 3 with no further complications.
Dieulafoy lesions as cause of upper gastrointestinal bleeding in a patient with portal hypertension

A 53-year-old man with a history of HIV and alcohol abuse presented to the emergency room with episodes of hematemesis and melena. Patient was taking naproxen almost daily for his chronic knee pain. He had pallor, tachycardia, orthostatic hypotension and black stools on rectal examination. His hemoglobin was 7.8 g/dl and platelet count was 115,000. Intravenous fluids, octreotide and packed red blood cells were given. Abdominal ultrasound revealed cirrhosis with high portal pressure. Upper endoscopy detected an actively bleeding gastroesophageal dieulafoy lesion that was bleeding uncontrollably, which necessitated the embolization of the left gastric artery. Hemoclips and epinephrine injections failed to control bleeding. An abdominal angiogram with coil embolization was performed, which successfully stopped the bleeding [Figure 1and Figure 2].
