Is the spleen an artery?

Gross anatomy The splenic artery is one of the terminal branches of the celiac trunk, passing left from the celiac axis across the left crus of diaphragm and left psoas muscle. It is a tortuous artery, running superior to the pancreas before turning forward into the splenorenal ligament to the hilum of the spleen.

Which part of the spleen is associated with arterial blood?

Blood vessels The arterial supply of the spleen comes from the tortuous splenic artery, which reaches the spleen as it travels through the splenorenal ligament.

How many arteries Does the spleen have?

The splenic artery divided into two or three lobar arteries, which supplied its corresponding lobe; each lobar artery subsequently divided into two to four lobular branches. Six to twelve lobular branches were observed entering the splenic substance at the hilum.

What artery supplies the spleen?

splenic artery
Spleen is the hemo-lymph organ, receives its arterial source by splenic artery (SA). SA is the largest branch of celiac trunk and tortuous in its course.

Where does splenic artery come from?

The splenic artery is the largest and most tortuous branch of the celiac trunk. After originating from the celiac trunk, the artery courses laterally, posterior to the stomach, and along the superior border of the pancreas.

What is a splenic arterial aneurysm?

Splenic artery aneurysm is defined as a condition where there is a focal dilation in the diameter of the splenic artery that is 50% greater than the normal vessel diameter. This is the most common visceral artery aneurysm reported making up about 60% to 70% of patients diagnosed with visceral artery aneurysms.

How big is the splenic artery?

The median internal diameter of the splenic artery was 5.35 mm (IQR: 4.67-6.18 mm) in patients with cirrhosis and portal hypertension and 4.60 mm (IQR: 4.32-5.32 mm) in healthy controls.

What does the splenic artery do?

The splenic artery, also known as the lienal artery, is an unpaired artery arising as the longest branch of the celiac trunk. This artery supplies the spleen, as well as large portions of the pancreas and stomach.

How serious is a splenic artery aneurysm?

Splenic artery aneurysm is a rare condition, however, potentially fatal. The importance of splenic artery aneurysm lies in the risk for rupture and life threatening hemorrhage.

How do they fix a splenic artery aneurysm?

The treatment options again are open surgery (mandatory in the setting of rupture), endovascular procedures, and laparoscopic surgery. Open surgical procedures include ligation of the splenic artery or aneurysm and aneurysmectomy with or without splenectomy.

What are the symptoms of a splenic artery aneurysm?

Patients with a splenic artery aneurysm before rupture are fairly asymptomatic; vague epigastric pain, left upper quadrant pain, and left shoulder pain are among the most common complaints. Radiologic studies for the diagnosis of splenic artery aneurysm include plain abdominal film, ultrasound, and angiography.

What causes splenic artery rupture?

Conclusion. Spontaneous splenic rupture is a rare condition leading to a rapidly progressing life-threatening hypovolemic shock due to intra-abdominal blood loss and can be caused by disorders such as acute and chronic infections, neoplastic disorders, and inflammatory noninfectious disorders.

How is splenic artery aneurysm diagnosed?

The diagnosis of splenic artery aneurysm can be made by Ultrasound, pulsed Doppler, CT, MRI and abdominal aortic arteriography, which is the gold standard.

How common is a splenic artery aneurysm?

Splenic artery aneurysm is a rare condition with a prevalence of 1%. It accounts for about 60% of all splanchnic arterial aneurysms. It only follows aortic and iliac arteries aneurysms as the third most common intra-abdominal aneurysm.

How rare is a splenic artery aneurysm?

Splenic artery aneurysm (SAA) is an uncommon, but potentially life-threatening, condition. It occurs in approximately 1 % of the population [1]. SAA accounts for approximately 60 % of all visceral arterial aneurysms [2].

Is a splenic artery aneurysm an emergency?

Splenic artery aneurysm (SAA) is an uncommon, but potentially life-threatening, condition.

Can you feel a splenic artery aneurysm?

Learning points. A splenic artery aneurysm, although rare, should be considered in the differential diagnosis of left upper quadrant abdominal pain with referred left shoulder pain.
