1. Abdominal Aorta

복강 내 주요 혈관인 복부 대동맥의 해부학적 구조와 주요 분지혈관들에 대해 설명하고 있습니다. 복부 대동맥은 L1-L4 척추체 앞쪽에 위치하며, 복강동맥, 상장간막동맥, 하장간막동맥 등의 주요 분지혈관을 내보내고 있습니다.
2. Celiac Trunk

복강동맥은 T12 척추체 앞쪽 대동맥 열공 바로 아래에서 분지되며, 좌위동맥, 비장동맥, 총간동맥 등의 3개 주요 분지혈관을 내보내고 있습니다. 이 혈관들은 식도 하부, 위, 십이지장 근위부, 비장, 간, 담낭, 췌장 등을 혈액 공급합니다.
3. Superior Mesenteric Artery (SMA)

상장간막동맥은 L1 척추체 앞쪽에서 분지되며, 복강동맥의 바로 하방에 위치합니다. 췌장 경부 뒤쪽으로 내려가며, 십이지장 하부부터 맹장, 상행결장, 횡행결장 근위 2/3 부분을 혈액 공급합니다.
4. Inferior Mesenteric Artery (IMA)

하장간막동맥은 L3 척추체 앞쪽부터 시작되며, 상장간막동맥의 하연에 위치합니다. 십이지장 수평부 뒤로 지나가며, 좌결장, 에스결장, 상직장동맥을 분지하여 하부 대장을 혈액 공급합니다.
5. Portal Venous System

상장간막정맥, 하장간막정맥, 비장정맥이 합쳐져 문맥을 형성합니다. 이 문맥은 췌장 경부 뒤쪽을 지나며, 위, 십이지장, 소장, 대장(직장 제외)의 정맥혈을 간으로 운반합니다. 간에서 정화된 혈액은 간정맥을 통해 하대정맥으로 흘러갑니다.

1. Abdominal Aorta

The abdominal aorta is the largest artery in the abdomen and plays a crucial role in supplying oxygenated blood to the lower body and abdominal organs. It originates from the thoracic aorta at the diaphragm and extends down to the level of the fourth lumbar vertebra, where it bifurcates into the common iliac arteries. Along its course, the abdominal aorta gives off several important branches, including the celiac trunk, superior mesenteric artery, and inferior mesenteric artery, which supply blood to the digestive organs, kidneys, and pelvic region. Understanding the anatomy and function of the abdominal aorta is essential for healthcare professionals, as it is a common site for aneurysms and other vascular pathologies that can have serious consequences if left untreated. Proper imaging and diagnostic techniques, as well as timely surgical or endovascular interventions, are crucial for managing conditions affecting the abdominal aorta and maintaining overall cardiovascular health.
2. Celiac Trunk

The celiac trunk is a critical artery that supplies blood to the upper abdominal organs, including the stomach, liver, spleen, and pancreas. Originating from the anterior aspect of the abdominal aorta, just below the diaphragm, the celiac trunk divides into three main branches: the left gastric artery, the splenic artery, and the common hepatic artery. These branches provide essential oxygenation and nutrients to the vital organs they supply. Proper understanding of the celiac trunk anatomy and its variations is crucial for healthcare professionals, as it is a common site for aneurysms, stenosis, and other vascular pathologies that can lead to serious complications if not properly diagnosed and managed. Imaging techniques, such as CT angiography and MRI, play a crucial role in evaluating the celiac trunk and its branches, allowing for early detection and appropriate treatment of any abnormalities. Maintaining the health of the celiac trunk is essential for overall abdominal organ function and well-being.
3. Superior Mesenteric Artery (SMA)

The superior mesenteric artery (SMA) is a critical blood vessel that supplies oxygenated blood to the majority of the small intestine, as well as the ascending and transverse colon. Originating from the anterior aspect of the abdominal aorta, just inferior to the celiac trunk, the SMA travels in the mesentery and provides numerous branches that nourish the digestive organs. Proper functioning of the SMA is essential for maintaining the health and integrity of the gastrointestinal tract, as it ensures adequate blood flow and nutrient delivery. Pathologies affecting the SMA, such as stenosis, thrombosis, or embolism, can lead to serious complications, including intestinal ischemia and infarction. Healthcare professionals must be well-versed in the anatomy and variations of the SMA to accurately diagnose and manage these conditions, often requiring advanced imaging techniques and prompt surgical or endovascular interventions. Preserving the health of the SMA is crucial for overall digestive system function and patient well-being.
4. Inferior Mesenteric Artery (IMA)

The inferior mesenteric artery (IMA) is a vital blood vessel that supplies oxygenated blood to the distal portion of the large intestine, including the descending colon, sigmoid colon, and rectum. Originating from the anterior aspect of the abdominal aorta, just above the aortic bifurcation, the IMA travels in the mesentery and provides several important branches, such as the left colic artery, sigmoid arteries, and superior rectal artery. Proper functioning of the IMA is essential for maintaining the health and integrity of the lower gastrointestinal tract, as it ensures adequate blood flow and nutrient delivery to these critical organs. Pathologies affecting the IMA, such as stenosis, thrombosis, or aneurysm, can lead to serious complications, including intestinal ischemia, bowel infarction, and even life-threatening conditions like mesenteric ischemia. Healthcare professionals must be well-versed in the anatomy and variations of the IMA to accurately diagnose and manage these conditions, often requiring advanced imaging techniques and prompt surgical or endovascular interventions. Preserving the health of the IMA is crucial for overall digestive system function and patient well-being.
5. Portal Venous System

The portal venous system is a critical component of the human circulatory system, responsible for transporting blood from the gastrointestinal tract, pancreas, and spleen to the liver. This unique system allows for the efficient delivery of nutrients, hormones, and other substances absorbed from the digestive organs to the liver, where they can be metabolized, stored, or further processed. The portal venous system is composed of the portal vein, which is formed by the confluence of the superior mesenteric vein and the splenic vein, as well as its numerous tributaries that collect blood from the abdominal organs. Proper functioning of the portal venous system is essential for maintaining liver health and overall digestive system homeostasis. Pathologies affecting the portal venous system, such as portal hypertension, portal vein thrombosis, or portal vein aneurysm, can lead to serious complications, including gastrointestinal bleeding, ascites, and liver dysfunction. Healthcare professionals must have a deep understanding of the anatomy and physiology of the portal venous system to accurately diagnose and manage these conditions, often requiring advanced imaging techniques and specialized interventions. Preserving the health of the portal venous system is crucial for maintaining overall bodily function and well-being.
