Endoscopic sclerotherapy for hemostasis of acute esophageal variceal bleeding.
2014
Introduction. Currently the most widely used methods for endoscopic control of esophageal varices bleeding are sclerotherapy and rubber band ligation. Although the superiority of band ligation (BL) over endoscopic sclerotherapy (SCL) for the secondary prophylaxis of variceal hemorrhage has been proven, the best approach for acute bleeding remains controversial. Patients and methods. We performed a retrospective study between January 2005 and May 2013. We selected 104 patients with gastrointestinal hemorrhage from rupture of esophageal varices treated with endoscopic sclerotherapy. The sclerosing agent used was 1% polidocanol in 89 cases, butyl-cyanoacrylate in 8 cases and sodium tetradecyls…
Transcatheter embolization of a renal artery pseudoaneurysm after open partial nephrectomy.
2011
Twelve days after an open partial nephrectomy, a 31-year-old man was re-admitted urgently for acute lumbar pain. An emergent helical computed tomography scan with intravenous contrast revealed a 3-cm renal artery pseudoaneurysm at the site of the partial nephrectomy, which was responsible for a large perirenal hematoma. Transarterial hyperselective embolization successfully occluded the pseudoaneurysm with less than 1 mL of N-butyl-2-cyanoacrylate, an embolizing agent less costly than coils. The kidney parenchyma was fully preserved.
Transgraft sac Embolization Combined with Graft Reinforcement for Refractory Mixed-Type Endoleak.
2018
International audience; An 80-year-old female underwent EVAR 4 years ago. She presented type II endoleak with sac expansion from 68 to 80 mm during 3-year follow-up after EVAR. Although she underwent translumbar percutaneous sac embolization, the AAA sac continued to enlarge, suggesting mixed-type endoleak including type I, II, and III. Transgraft direct sac angiography revealed endoleak cavity without demonstrable feeding vessel. Transgraft sac embolization using n-butyl cyanoacrylate and graft reinforcement was performed concurrently, without complications. The graft reinforcement consisted of graft extension for eliminating occult type I endoleak, and relining for eliminating occult type…
Evaluation of polyalkylcyanoacrylate nanoparticles as a potential drug carrier: preparation, morphological characterization and loading capacity.
1993
Some physicochemical behaviours were investigated of polyethyl- (PECA) and polyisobutylcyanoacrylate (PICA), which, in recent years, have been proposed as nanoparticle colloidal systems for drug carrying. We observed the influence of preparation conditions, such as pH value and surfactant concentration, on parameters such as particle size and polymer molecular weight. Lower operating pH values (0-2) resulted in smaller nanoparticles than those prepared at pH 5.5. The polymer molecular weight was also a function of pH: low molecular weight at low pH and vice-versa. The surfactant concentration positively influenced main particle size and polymer molecular weight. These trends were independen…
Transcatheter embolization of the kidney with butyl-2-cyanoacrylate: Experimental and clinical results
1978
The technique and efficacy of therapeutic catheter embolization of the kidney with butyl-2-cyanoacrylate (Histoacryl) were studied in 80 rabbits (including control groups) and in 10 dogs. A mixture of butyl-2-cyanoacrylate, 50% glucose, and tantalum powder was used for the embolization. Complete and permanent vascular occlusion was found in nearly all cases. The main complication observed was a reflux of embolizing material into the lumbar arteries, which occurred in seven rabbits. Clinically, therapeutic embolization was performed in six patients with hypernephroma. The indication for embolization in these patients, as well as in two others with iatrogenic lesions, was pronounced hematuria…
