  • In spite of the important role played by the sympathetic nervous system in the cardiovascular, renal, respiratory, and metabolic functions, chronic sympathectomy, induced experimentally by guanethidine (Gu) treatment [ 10 ], produces only small alterations when administered either to neonatal or adult rats.

  • The effects of peripheral sympathectomy with nerve growth factor antiserum (NGFAS) on blood pressure, systemic hemodynamics, myocardial function, myocardial hypertrophy, and renin were studied in male spontaneously hypertensive (SH) rats of the Okamoto strain and normotensive control Kyoto-Wistar (WKY) rats.

  • The development of hypertension in SHR was prevented by sympathectomy, but the blood pressure (BP) was still higher than in age-matched WKY rats. (ahajournals.org)
  • Adventitial area was increased in some mesenteric arteries of SHR and WKY rats by sympathectomy, and demedullation caused a further increase in the size of adventitia in WKY rats. (ahajournals.org)
  • Heart weight in SHR was normalized to the level found in WKY rats by sympathectomy and demedullation. (ahajournals.org)
  • surgery
  • RESULTS: All 306 lumbar sympathectomies were performed in retroperitoneoscopic technique and in none of the cases a conversion to open surgery was necessary. (springer.com)
  • Chronic
  • Chronic ventricular sympathectomy elicits changes in the coronary circulation, myocardial oxygen consumption and size of infarction resulting fromcoronary occlusion. (unt.edu)
  • Chemical sympathectomy with 6-hydroxydopamine was carried out either neonatally, in the immunisation phase, or immediately before AIA elicitation, or during the chronic phase. (bmj.com)
  • Neither sympathectomy in the immunisation phase nor in the chronic phase influenced AIA. (bmj.com)
  • significantly reduced
  • Morphometric measurements of the mesenteric arteries showed that sympathectomy significantly reduced the medial mass in the mesenteric arteries of SHR, mainly through a reduction in the number of smooth muscle cell layers. (ahajournals.org)

  • The authors specifically attempted to induce a complete sympathectomy that would ablate adrenal and cardiovascular responses to a cold pressor stimulus applied in the upper extremity. (asahq.org)
  • HYPERTENSION
  • It is only in the past seven years that the more radical lumbodorsal sympathectomy developed by Dr. Reginald Smithwick has shown sufficiently good results to revive enthusiasm over the surgical treatment of hypertension. (annals.org)

  • results
  • We appreciated that these groups are different, although we wanted a control group that we were sure would develop a sympathectomy so as to avoid equivocal results. (asahq.org)
