Patients with compressive symptoms or those with AVF should preferentially be treated with OR.”
“Purpose: To describe our experiences with the treatment of visceral artery aneurysms (VAA) by transcatheter coil embolization and to propose indications for treating VAA by this method.
Methods: We treated 22 patients with VAA by coil embolization; 9 had splenic-, 7 renal-, 4 pancreaticoduodenal arcade-, and 2 proper hepatic artery aneurysms. All nine splenic artery aneurysms patients presented with chronic hepatitis-C; four had hepatocellular carcinoma. Of the seven renal artery aneurysms patients,
four were hypertensive and three had rheumatoid arthritis. Both pancreaticoduodenal
arcade artery aneurysms patients manifested severe stenosis of the NU7441 celiac axis. Our transcatheter coil embolization procedure includes coil embolization and coil-packing WZB117 mw of the aneurysmal sac, preserving the native arterial circulation.
Results: Transcatheter coil embolization with aneurysm packing was technically successful in 16 (72.7%) of the 22 patients and the native arterial circulation was preserved. Postprocedure angiograms confirmed complete disappearance of the VAA. In four of the nine splenic artery aneurysm patients, the native arterial circulation was not preserved. In one renal artery aneurysm patient, stenosis at the aneurysmal neck necessitated placement of a stent before transcatheter coil embolization. Magnetic resonance angiographs obtained during the follow-up period (mean 27 months) demonstrated complete
thrombosis of the VAA in all 22 patients. Infarction occurred in one splenic- and two renal artery aneurysms patients; the latter developed flank pain and fever after the procedure.
Conclusions: Transcatheter coil embolization is an effective alternative treatment for patients with saccular and proximal VAA. In particular, the isolation Rapamycin solubility dmso technique using coil embolization is advantageous in splenic artery aneurysm patients.”
“Antagonists of the substance P (SP) preferring neurokinin 1 receptor (NK1R) represent a promising novel class of drugs for the treatment of stress-related disorders such as depression and anxiety disorders; however, the involved neuronal pathways releasing SP in response to stressors are ill defined. By using in vivo microdialysis in combination with a highly sensitive and selective radioimmunoassay we found that exposure to forced swim stress increased SP release in the rat lateral septum (LS), a key area in processing emotions and stress responses. Acute administration of the selective NK1R antagonist L-822429 injected either systemically or locally into the LS reduced passive and facilitated active stress-coping strategies in the forced swim test.
