Novel Compliant Scaffold with Specific Design for Venous System: Results of a Porcine Model Study
No full textBackground. Stenting has become the first-line treatment of obstructive venous disease because of poor results of balloon angioplasty. This preclinical study aimed to investigate the safety and efficacy profile of a novel compliant venous scaffold (CVS) denominated Petalo CVS, specifically designed for venous diseases. Materials and Methods. Twelve healthy pigs weighing 90 kg were used to test Petalo CVS. The devices were implanted into the internal jugular veins (IJVs) using a femoral vein percutaneous approach. The safety profile including the success rate of device releasing, anchoring, and positioning was evaluated immediately. Fracture, migration, primary patency, and endothelial response were assessed at 1, 2, 3, and 6 months after the study procedure. Results. A total of 32 devices were successfully released in both IJVs. No procedure- or device-related complications were reported, and all pigs successfully completed the different scheduled follow-up periods. The primary patency rate was 100%, and no fracture or migration of the device into the brachiocephalic trunk was reported. Histological examination revealed only minimal lesions with minimal or absent inflammatory reaction surrounding the incorporated metallic rods. Conclusions. This porcine model study showed a promising safety and efficacy profile of Petalo CVS, a novel endovenous device based on specific concepts.</jats:p
Blunt liver injury: from non-operative management to liver transplantation
No full textI.F.= 0.511
Abstract: Therapeutic options for blunt hepatic trauma include both non-operative and operative management. We have reviewed our experience of the management of blunt hepatic trauma, from non-operative to liver transplantation. A total of 72 patients with blunt hepatic injury observed at the first surgical unit of Padua in a 3-year period (1998-2000) were analysed; we also included a patient who had a liver transplant in 1993 for severe liver trauma. Twenty-nine patients (39.7%) were treated conservatively, with a 93% success rate; 60.3% were treated surgically. Suture hepatorraphy was the most common procedure performed (52.3%). Advantages of non-operative management in our experience were the reduced need for transfusion (1.1 U versus 4.3 U) with 92% of patients not needing transfusion, and a reduced stay in the intensive care unit; there was no liver-related mortality. The overall morbidity in surgical patients was 30%, with 16% liver-related complications. Twelve surgical patients (27.2%) died, with a liver-related mortality of 18.2%. A large number of patients may present with an associated endo-abdominal injury, even in low-grade liver trauma, requiring rapid laparotomy. In high-grade hepatic trauma, the evolution toward liver failure is an indication for liver transplantation. (C) 2002 Elsevier Science Ltd. All rights reserve

Laparoscopic treatment of simple hepatic cysts and polycystic liver disease
No full textBackground: The authors present their experience in the laparoscopic management of hepatic cysts and polycystic liver disease (PLD). Methods: Between January 1996 and January 2002, 16 patients underwent laparoscopic liver surgery. Indications were solitary giant cysts (n = 10) and PLD (n = 6). Data were collected retrospectively. Results: Laparoscopic fenestration was completed in 15 patients. Median operative time was 80 min. There was no deaths. Complications occurred in four patients: one patient with a solitary liver cyst experienced diarrhea, while a pleural effusion, a bleeding from the trocar-insertion site, and ascites occurred in three patients with PLD. Median follow-up was 34 months. There was one asymptomatic recurrence (11%) in one patient with a solitary cyst. Two patients with PLD had a symptomatic recurrence of a liver cyst. Conclusion: Laparoscopic fenestration could be the preferred treatment of solitary liver cysts and PLD. Adequate selection of patients and type of ..
