  • occlusion
  • Depending on the how complete occlusion is, and whether or not collateral drainage is available, the combination of back pressure, and bowel wall thickening can lead to inadequate tissue perfusion leading to intestinal ischaemia, infarction and eventual necrosis 1 . (radiopaedia.org)
  • catheter
  • Ultrasound and catheter mesenteric angiography are reported to have approximately 70% sensitivity 3 but in practice are infrequently requested as a first line investigation, unless the presentation suggests another diagnosis (e.g. cholecystitis). (radiopaedia.org)
  • Thrombolytic agents can be introduced either via a superior mesenteric artery catheter or a transhepatic transportal retrograde approach, whereas mechanic clot lysis can only be achieved via a retrograde transhepatic venous approach 2 . (radiopaedia.org)
  • superficial
  • Lower extremity computed tomography angiography can help predict technical success of endovascular revascularization in the superficial femoral and popliteal artery. (stanford.edu)
  • Bowel ischemia severity ranges from mild (generally transient superficial changes of intestinal mucosa) to more dangerous and potentially life-threatening transmural bowel wall necrosis 1 . (radiopaedia.org)
  • tract
  • Similarly, the limited investigation of the superior mesenteric artery (blood vessel that supplies the greatest volume of blood to the intestinal tract) blood flow velocities (SMA BFV) revealed that the expected post-prandial increase in SMA BFV disappeared following the PRBC, placing the fed neonates receiving blood transfusion at higher risk for NEC (12).

  • It happens when your baby's intestinal tract doesn't form as it should during pregnancy. (stanfordchildrens.org)
  • damage
  • The aim of the study was to elucidate the involvement of polymorphonuclear leucocytes in post-ischaemic intestinal damage. (bmj.com)
  • Internal
  • Some axons leave the internal carotid artery at the foramen lacerum, inside the skull, to form the deep petrosal nerve, which runs to the pterygoid ganglion. (thefreedictionary.com)
