Branches of thoracic & abdominal aorta

  1. 1. BRANCHES OFTHORACIC &ABDOMINNAL AORTASUBMITTED TO: SUBMITTED BY:Dr. Zeeshan Akbar Waqas Nawaz 11-arid-975
  2. 2. Branches of thoracicaorta IN ADDITION TO THE CORONARY ARTERIES AND COMMON BRACHIO-CEPHALIC TRUNK, THE THORACIC PART OF AORTA GIVES OFF BRANCHES TO THE THORACIC WALLS AND VISCERA AND TO SPINAL CORD AND ITS MEMBRANE. (1).VISERAL BRANCHES…………….BRONCHIAL AND OESOPHAGEAL (2).PARIETAL BRANCHES…………..INTERCOSTAL AND PHRENIC
  3. 3. (1) VISCERAL BRANCHES BRONCHIAL-OESOPHAGEAL ARTERY: ORIGIN: ARISES AT THE SIXTH THORACIC VERTEBRA FROM AORTA-IT DESCENDS OVER THE RIGHT FACE OF THE AORTA TOWARDS BIFURCATION OF TRACHEA AND DIVIDED INTO BRONCHIAL ANAOESOPHAGIAL BRANCHES. BRONCHIAL ARTERY: IT CROSSES THE LEFT FACE OF OESOPHAGOUS TO THE BIFURCATION OF TRACHEA WHERE IT DIVIDES INTO RIGHT AND LEFT BRANCHES.EACH ENTER INTO HILUS OF CORRESPONDING LUNG.
  4. 4. Cont… OESOPHAGEAL ARTERY: IT IS SMALL VESSEL WHICH PASSES BACKWARD DORSAL TO THE OESOPHAGOUS IN THE POSTERIOR MEDIASTINUM AND ANASTOMOSIS WITH THE OESOPHAGEAL BRANCH OF THE GASTRIC ARTERY AND GIVES OFF BRANCHES WHICH PASSES BETWEEN THE LAYERS OF LIGAMENT OF THE LUNGS.
  5. 5.

THE FIFTH AND SIXTH SPRINGS FROM A COMMON STEM. EACH PASSES THE BODY OF VERTEBRA TO INTERCOSTALS SPACE. IT DIVIDES INTO  DORSAL BRANCHES  VENTERAL BRANCHES
  6. 6.  DORSAL BRANCHES: IT GIVES OFF SPINAL BRANCHES WHICH PASSES THROUGH INTERVERTEBERALFORAMEN.A MUSCULAR BRANCH PASSES TO MUSCLE AND SKIN OF BACK. VENTERAL BRANCHES: IT IS MUCH LARGE. ORIGIN: IT DESCEND IN MIDDLE OF INTERCOSTALS SPACE BETWEEN INTRCOSTAL MUSCLES. SUPPLIES:IT SUPPLIES INTERCOSTALSMUSCLE,THERIBS,AND PLEURA
  7. 7.  PHARENIC ARTERIES: ORIGIN: TWO OR THREE SMALL BRANCHES WHICH ARISE AT HIATUS AORTICUS FROM VENTERAL ASPECT OF AORTA. SUPPLIES: THEY SUPPLIES CRURA OF DIAPGRAM.
  8. 8. BRANCHES OF ABDOMINAL AORTA: THESE BRANCHES SUPPLIES 1) WALLS OF ABDOMINAL CAVITY 2) SOME BRANCHES SUPPLIES SPINAL CORD 3) SOME EXTEND INTO PELVIS AND SACROTUM
  9. 9. VISCERAL BRANCHES (1).COELIAC ARTERY IT IS UN PAIRED VESSEL ORIGIN: ARISE FROM VENTERAL ASPECT OF AORTA IT IS FURTHER DIVIDED INTO THREE BRANCHES GASTRIC ARTERY IT GIVES OFF OESOPHAGOUS AND PANCREATIC BRANCHES IT DIVIDED BEHIND THE CARDIA INTO ANTERIOR AND POSTERIOR BRANCHES
  10. 10. Cont… ANTERIOR BRANCHES: THEY SUPPLIES THE PARIETAL SURFACE OF STOMACH POSTERIOR BRANCHES: THEY SUPPLIES THE VISCERAL SURFACE OF STOMACH OESOPHGEAL BRANCHES: IT PPASSES THROUGH HIATUS OESOPHAGOUS INTO THORACIC CAVITY ABOVE THE OESOPHAGOUS AND ANASTOMOSES WITH THE OESOPHAGEAL BRANCH OF BRONCHO- OESOPHAGEAL CAVITY.
  11. 11. HEPATIC ARTERY: LARGER THAN GASTRIC IT PASSES FORWARD AND TO THE RIGHT AND VENTERALLY ON DORSAL SURFACE OF PANCREAS IT DIVIDED INTO 3-4 BRANCHES WHICH ENTER THE PORTAL FISSURE OF LIVER IT ALSO GIVES OFF CO-LATERAL BRANCHES PANCREATIC BRANCHES: GIVES OFF AN ARTERY CROSSES THE PANCREAS PYLORIC ARTERY: ORIGIN: ARISE FROM DUOENUM AND GIVES OFF ITS BRANCHES TO PYLORUS. GASTRO-DUODENAL ARTERY: ORIGIN: IT ALSO ARISE FROM DUODENUM IT ALSO GIVES TWO BRANCHES. RIGHT GASTRO EPIPLOIC ARTERY: IT SUPPLIES STOMACH AND DUODENUM PANCREATIC-DUEDENAL ARTERY: IT SUPPLIES PANCREAS AND DUEDENUM
  12. 12.  SPLENIC ARTERY: LARGEST BRNCH OF CORLIAC ARTERY. IT PASSES THE LEFT EXTRIMITY OF PANCRAS AND CROSS THE STOMACH. IT GIVES OFF PANCREATIC BRANCHES: SUPPLIES: THEY SUPPLIES THE LEFT EXTRIMITY OF PANCREAS SPLENIC BRANCHES: SUPPLIES: THEY SUPPLIES THE SPLEEN SHORT GASTRIC BRANCHES: SUPPLIES:IT SUPPLIES YHE GREATER CURVATURE OF STOMACH LEFT GATRO EPIPLOIC ARTERY: IT IS CONTINUATION OF SPLENIC ARTERY SUPPLIES:IT SUPPLIES THE GREATER CURVATURE OF STOMACH
  13. 13. (2) ANTERIOR MESENTRIC ORIGIN: ARISE FROM VENTERAL FACE OF AORTA AT FIRST LUMBER VERTEBRA. IT IS LARGE UNPAIRED TRUNK IT PASSES VENTERALLY BETWEEN VANA CAVA AND ADRENAL IT GIVES OFF BRANCHES…..
  14. 14.  LEFT BRANCH: IT GIVES OFF 15-20 BRANCHES OF SMALL INTESTINE RIGHT BRANCHES: IT GIVES OFF SMALL BRANCHES ILEAL: IT PASSES THE TERMINAL PART OF ILEUM LATERAL COCCYGEAL ARTERY: IT PASSES BETWEEN COECUM AND ORIGIN OF COLON MEDIAL COCCYGEAL ARTERY: IT PASSES ALONG THE APEX OF COECUM
  15. 15.  VENTERAL COLIC ARTERY: IT PASSES THE VENTERAL SURFACE OF COLON WHERE IT UNITES WITH DORSAL COLIC ARTERY ANTERIOR BRANCHES :IT GIVES OFF DORSAL COLIC ARTERY: IT PASSESS THE GREATER COLON AND JOINS THE VENTERAL COLIC ARTERY MEDIAL COLIC ARTERY: IT PASSES THE SMALL COLON AND ENTER THE COLIC MESENTRY
