Chapter 9----Vascular System Flashcards
Which one of the following vascular structures courses between the aorta and SMA?
Left renal vein
(The left renal vein flows from the renal hilum, posterior to the SMA, and anterior to the aorta to enter the lateral wall of the IVC)
Which one of the following vascular structures relates to the medial and posterior borders or to the pancreatic body and tail?
Splenic Vein
(The splenic vein passes anteriorly to the aorta and IVC and generally relates to the medial and posterior borders of the pancreatic body and tail)
Which one of the following veins begins at the hilum of the spleen and is joined by the short gastric and left gastroepiploic vein?
Splenic Vein
(The splenic vein begins at the hilum of the spleen. It is subsequently joined by the short gastric and left gastroepiploic veins)
Which one of the following vessels passes anterior to the uncinate process of the pancreas?
SMA
The superior mesenteric artery courses posterior to the neck of the pancreas and anterior to the uncinate process
Which vascular structure is used as a landmark in locating the celiac trunk?
SMA
The superior mesenteric artery may be used as a landmark in locating the celiac trunk.
Budd-Chiari syndrome demonstrates thrombosis of the
Hepatic veins
Budd-Chiari–is rare, and 30% of patients with this syndrome are idiopathic. The presence of a “typical” blood flow in the hepatic veins permits the exclusion of Budd-Chiari syndrome.
In patients with lower trunk and leg edema and a dilated IVC, a(n) _______________ should be suspected.
Atrioventricular fistula
–may demonstrate clinical symptoms, including low back pain, abdominal pain, progressive cardiac decompensation, a pulsatile abdominal mass associated with a bruit, and the development of massive swelling of the lower trunk and lower extremities.
Renal arteries branch from the lateral wall of the aorta
Inferior to the SMA
The arterial supply to the gallbladder is via the:
cystic artery
The clinical signs of leg edema, low back pain, pelvic pain, gastrointestinal complaints, and renal and liver problems may represent:
IVC thrombosis
The distribution of the superior mesenteric artery is to the
Small intestine and the proximal half of colon
The duodenum and parts of the stomach are supplied by the:
Gastroduodenal artery
Remember that the GDA is located in the anterolateral portion of the pancreatic head
The gastroduodenal artery is a branch of the:
Common hepatic artery
The inferior mesenteric artery distributes blood to the:
Left transverse colon, descending colon, sigmoid, and rectum
The IVC courses anteriorly to enter the
Right Atrium
(The IVC ascends vertically through the retroperitoneal space on the right side of the aorta, posterior to the liver, and pierces the central tendon of the diaphragm at the level of the eighth thoracic vertebra to enter the right atrium of the heart)
