What Is the Splenic Artery?
It is the largest branch of the celiac artery and runs to the left along the upper edge of the pancreas. After the splenic artery sends several branches to the pancreas during its travel, it travels between the spleen-renal ligament and near the spleen hilum. It first divides the small branches of the short gastric artery above and the left artery of the gastric omentum below. Then divide 2 to 3 terminal branches into the spleen.

- It is the largest branch of the celiac artery and runs to the left along the upper edge of the pancreas. After the splenic artery sends several branches to the pancreas during its travel, it travels between the spleen-renal ligament and near the spleen hilum. It first divides the small branches of the short gastric artery above and the left artery of the gastric omentum below. Then divide 2 to 3 terminal branches into the spleen.
1 Physiological significance of splenic artery 1, splenic artery:
- This artery divides into the spleen from right to left to the spleen hilum along the upper edge of the pancreas. The branches of the splenic artery are: the left gastric omentum artery, which runs from the left to the right along the great curvature of the stomach, and coincides with the right gastric omentum artery; the short gastric artery to the base of the stomach; in addition, the splenic artery (some branches along the way to the pancreatic body and Tail. Splenic artery embolism can seriously damage the function of the spleen. One or two posterior gastric arteries are issued, behind the peritoneum of the omental sac behind the peritoneum of the omentum sac, ascending through the gastrosacral ligament and distributed in the upper part of the posterior wall of the stomach. Nearby, 3 to 5 short gastric arteries were sent through the gastric and spleen ligaments to the bottom of the stomach; the left gastric omentum artery went right along the great curvature of the stomach, and along the way, the gastric branch and the omental branch nourished the stomach and the greater omentum. The right branch of the branch and the gastroretinal anastomosis synthesize an arterial arch.
2 Splenic artery 2. Splenic aneurysm:
- A rare surgical disease. The etiology is not clear. Generally, it is the result of a variety of factors. The related causes are congenital arterial tissue defects, portal hypertension, arteriosclerosis, trauma, splenic artery embolism, splenic arteritis, pregnancy, and syphilis. There are three types according to the tumor site: away from the splenic hilum, near the splenic hilum, and intermediate. Generally, there are no symptoms before rupture, but if the tumor is relatively large, it can cause corresponding symptoms. Once ruptured, it shows sudden abdominal pain, intra-abdominal bleeding, and hemorrhagic shock. B-ultrasound, CT, and selective abdominal angiography can be clearly displayed. Once diagnosed, surgical treatment should be active.
3 Splenic artery 3, the main points of diagnosis of splenic aneurysm:
- 1. Clinical manifestations: the vast majority have no specific symptoms and signs. When the tumor is large, the left upper abdomen smells vascular noise, or the left shoulder and back radiate pain. Rupture of the tumor causes massive intra-abdominal bleeding.
- 2. Auxiliary examination: It is mostly found by accident in plain abdominal X-ray film, color Doppler ultrasound, CT, MRI, angiography and other diseases.
