- Infusion of Recombinant Human Tissue Plasminogen Activator Through the Superior Mesenteric Artery in the Treatment of Acute Mesenteric Venous Thrombosis(2011) LEAL FILHO, Joaquim Mauricio da Motta; SANTOS, Aline Cristine Barbosa; CARNEVALE, Francisco Cesar; SOUSA JR., Wilson de Oliveira; GRILLO JR., Luiz Sergio Pereira; CERRI, Giovanni GuidoAcute mesenteric venous thrombosis is an uncommon condition that is usually treated with systemic anticoagulation. Catheter-directed thrombolysis through the superior mesenteric artery may be a viable adjunct to treat this morbid condition. In the present article, we have described a case of superior mesenteric venous thrombosis treated with catheter-directed infusion of tissue plasminogen activator through the superior mesenteric artery.
- Ten-year Retrospective Study of Treatment of Malignant Colonic Obstructions with Self-expandable Stents(2011) GREGORIO, Miguel A. de; LABORDA, Alicia; TEJERO, Eloy; MIGUELENA, Jose M.; CARNEVALE, Francisco C.; BLAS, Ignacio de; GIMENEZ, Mariano; MAYNAR, Manuel; D'AGOSTINO, HoracioPurpose: To describe the use of self-expandable metallic stents to manage malignant colorectal obstructions and to compare the radiation dose between fluoroscopic guidance of stent placement and combined endoscopic and fluoroscopic guidance. Materials and Methods: From January 1998 to December 2007, 467 oncology patients undergoing colorectal stent placement in a single center were included in the study. Informed consent was obtained in all cases. All procedures were performed with fluoroscopic or combined fluoroscopic and endoscopic guidance. Inclusion criteria were total or partial colorectal obstruction of neoplastic origin. Exclusion criteria were life expectancy shorter than I month, suspicion of perforation, and/or severe colonic neoplastic bleeding. Procedure time and radiation dose were recorded, and technical and clinical success were evaluated. Follow-up was performed by clinical examination and simple abdominal radiographs at 1 day and at I, 3, 6, and 12 months. Results: Of 467 procedures, technical success was achieved in 432 (92.5%). Thirty-five treatments (7.5%) were technical failures, and the patients were advised to undergo surgery. Significant differences in radiation dose and clinical success were found between the fluoroscopy and combined-technique groups (P < .001). Total decompression was achieved in 372 cases, 29 patients showed remarkable improvement, 11 showed slight improvement, and 20 showed clinical failure. Complications were recorded in 89 patients (19%), the most significant were perforation (2.3%) and stent migration (6.9%). Mean interventional time and radiation dose were 67 minutes and 3,378 dGy.cm(2), respectively. Conclusions: Treatment of colonic obstruction with stents requires a long time in the interventional room and considerable radiation dose. Nevertheless, the clinical benefits and improvement in quality of life justify the radiation risk.

- Which is the best technique for hepatic venous reconstruction in pediatric living-donor liver transplantation? Experience from a single center(2011) TANNURI, Uenis; SANTOS, Maria M.; TANNURI, Ana Cristina A.; GIBELLI, Nelson E.; MOREIRA, Airton; CARNEVALE, Francisco C.; AYOUB, Ali A.; MAKSOUD-FILHO, Joao G.; ANDRADE, Wagner C.; VELHOTE, Manoel C. P.; SILVA, Marcos M.; PINHO-APEZZATO, Maria L.; MIYATANI, Helena T.; GUIMARAES, Raimundo R. N.Background/purpose: The introduction of the piggyback technique for reconstruction of the liver outflow in reduced-size liver transplants for pediatric patients has increased the incidence of hepatic venous outflow block (HVOB). Here, we proposed a new technique for hepatic venous reconstruction in pediatric living-donor liver transplantation. Methods: Three techniques were used: direct anastomosis of the orifice of the donor hepatic veins and the orifice of the recipient hepatic veins (group 1); triangular anastomosis after creating a wide triangular orifice in the recipient inferior vena cava at the confluence of all the hepatic veins (group 2); and a new technique, which is a wide longitudinal anastomosis performed at the anterior wall of the inferior vena cava (group 3). Results: In groups 1 and 2, the incidences of HVOB were 27.7% and 5.7%, respectively. In group 3, no patient presented HVOB (P = .001). No difference was noted between groups 2 and 3. Conclusions: Hepatic venous reconstruction in pediatric living-donor liver transplantation must be preferentially performed by using a wide longitudinal incision at the anterior wall of the recipient inferior vena cava. As an alternative technique, triangulation of the recipient inferior vena cava, including the orifices of the 3 hepatic veins, may be used.
- Perioperative Temporary Occlusion of the Internal Iliac Arteries as Prophylaxis in Cesarean Section at Risk of Hemorrhage in Placenta Accreta(2011) CARNEVALE, Francisco Cesar; KONDO, Mario Macoto; SOUSA JR., Wilson de Oliveira; SANTOS, Aline Barbosa; LEAL FILHO, Joaquim Mauricio da Motta; MOREIRA, Airton Mota; BARONI, Ronaldo Hueb; FRANCISCO, Rossana Pulcinelli Vieira; ZUGAIB, MarceloPurpose The purpose of this study was to describe the preliminary results of prophylactic temporary balloon occlusion of the internal iliac arteries for bleeding control in patients with placenta accreta during cesarean hysterectomy. Methods From May 2006 to March 2010, 21 patients diagnosed with placenta accreta using ultrasound and/or magnetic resonance imaging were submitted to prophylactic balloon occlusion before hysterectomy. Fluoroscopy, balloon occlusion time, surgical duration, intraoperative blood loss, transfusion volume, and procedure complications were analyzed. Results The mean age was 30.5 years with a mean of 3.6 previous gestations. Imaging studies revealed that all patients had placenta accreta and all were submitted to cesarean hysterectomy. One hysterectomy was due to previous diagnosis of fetal death and another due to cesarean with uterine curettage. Mean fluoroscopy time was 7.5 min, balloon occlusion time was 164 min, and surgery duration was 260 min. Estimated blood loss was 1,671.5 ml with mean reposition fluids of 3,538 ml of crystalloids, 309.5 ml of colloids, and 1.24 ml of packed red blood cells. Two patients were submitted to thromboembolectomy due to prolonged surgical time. There was no maternal or fetal mortality related to the procedure. Conclusions The results demonstrated that prophylactic balloon occlusion of internal iliac artery is a safe method and appears to reduce blood loss and transfusion requirements in patients diagnosed with placenta accreta who undergo cesarean hysterectomy. Antenatal imaging diagnosis of placenta accreta enables preoperative planning.
