  • venous
  • 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)
  • diagnosis
  • 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)
  • small mesenteric
  • We compared the sensitivity of depolarization (KCl)-induced constriction of rat small mesenteric arteries (MAs) and veins (MVs) to the dilator effect of CCBs. (ahajournals.org)
  • The purpose of the current in vitro study was to determine whether short-term acute hypoxia has a direct vasoconstrictive effect on isolated small mesenteric veins of the rabbit, to evaluate the mechanism of the hypoxic response, and to examine the effects of halothane, isoflurane, and enflurane. (asahq.org)
  • vascular
  • Laparoscopic pancreaticoduodenectomy with vascular reconstruction can be performed safely in selected cases of pancreatic head cancer with vein involvement. (springer.com)
  • systemic
  • Acute systemic hypoxia reduces splanchnic capacitance via mesenteric venoconstriction because of combined influences on the central nervous system, peripheral chemoreflex activation, and sympathetic efferent transmission. (asahq.org)
  • We have reported previously that mesenteric venoconstriction occurring during acute systemic hypoxia in intact rabbits is markedly reduced by inhaled halothane. (asahq.org)
  • Management options for superior mesenteric and portal vein thrombosis include systemic anticoagulation, endovascular infusion of thrombolytic agents, and surgical thrombectomy. (radiopaedia.org)
  • S.N was a 28-year-old female in End Stage Renal Failure (ESRF), with systemic lupus erythematosus and recurrent lower limb deep vein thrombosis since adolescence. (surgeryresearchjournal.com)
  • In addition, a thorough work-up needs to be done in order to elucidate the etiology, especially underlying systemic illness, in those patients diagnosed with portal vein thrombosis. (springermedizin.de)
  • mesentery
  • Experiments were performed on 268 rings of small (500-800 micro meter in diameter) veins isolated from mesentery of the terminal ileum of the rabbit. (asahq.org)
  • ileum
  • Grossly, the specimen received was composed of a portion of ileum anastomosed to a markedly dilated colon, including the sigmoid colon, and notable for extensive fat wrapping associated with dense, indurated mesenteric adipose tissue, particularly in the mid and distal colon (Figure 1(a) ).

  • canine
  • 11 Additionally, voltage-elicited Ca 2+ currents in patch-clamped SMCs from canine saphenous vein are blocked by nanomolar concentrations of CCBs. (ahajournals.org)
  • Norepinephrine (NE), a classic neurotransmitter in the sympathetic nervous system, induces vasoconstriction of canine isolated mesenteric vein that is accompanied by a sustained membrane depolarization. (biomedcentral.com)
  • In the present study we hypothesized that phosphatidylinositol 3-kinase (PI3K) and protein kinase C (PKC) are involved in the electrical field stimulation (EFS)-induced slow membrane depolarization (SMD) in canine isolated mesenteric vein. (biomedcentral.com)
  • The resting membrane potential of canine mesenteric vein smooth muscle cells was -68.8 ± 0.8 mV. (biomedcentral.com)
  • Neuronally-released NE stimulates smooth muscle α 2 -adrenoceptors and activates PI3K and atypical PKC in the canine mesenteric vein. (biomedcentral.com)
