RESUMO
PURPOSE: To introduce percutaneous selective injection of autologous platelet-rich fibrin as a novel technique for persistent bile leakage repair and sharing the results of our preliminary experience. MATERIALS AND METHODS: Seven patients (57.1% females; mean age 69.6 ± 8 years) with the evidence of persistent bile leak secondary to hepatobiliary surgery and ineffective treatment with percutaneous transhepatic biliary drainage were submitted to fibrin injection. Platelet-rich fibrin, a dense fibrin clot promoting tissue regeneration, was obtained from centrifuged patient's venous blood. Repeated percutaneous injections through a catheter tip placed in close proximity to the biliary defect were performed until complete obliteration at fistulography. Technical and clinical success were evaluated. RESULTS: Bile leaks followed pancreaticoduodenectomy in five and major hepatectomy in two patients. Technical success defined as fibrin injection at BD site was achieved in all seven patients, and clinical success defined as a complete healing of the BD at fistulography was achieved in six patients. The median time to BD closure was 76.7 ± 40.5 days and the average procedure number was 3 ± 1 per patient. In one patient, defect persistance after four treatments required gelatin sponge injection. No major complications occurred. One case of post-procedural transitory hyperpirexia was registered. CONCLUSION: In persistent biliary defects, despite prolonged biliary drainage stay, percutaneous injection of autologous platelet-rich fibrin appears as a readily available and feasible emergent technique in promoting fistulous tracts obliteration still mantaining main ducts patency.

This retrospective study shows the results of a 2 years application of a clinical pathway concerning the indications to NOM based on the patient's hemodynamic answer instead of on the injury grade of the lesions.We conducted a retrospective study applied on a patient's cohort, admitted in "Azienda Ospedaliero-Universitaria Ospedali Riuniti of Ancona" and in the Digestive and Emergency Surgery Department of the Santa Maria of Terni hospital between September 2015 and December 2017, all affected by blunt abdominal trauma, involving liver, spleen or both of them managed conservatively. Patients were divided into 3 main groups according to their hemodynamic response to a fluid administration: stable (group A), transient responder (group B) and unstable (group C). Management of patients was performed according to specific institutional pathway, and only patients from category A and B were treated conservatively regardless of the injury grade of lesions.From October 2015 to December 2017, a total amount of 111 trauma patients were treated with NOM. Each patient underwent CT scan at his admission. No contrast pooling was found in 50 pts. (45.04%). Contrast pooling was found in 61 patients (54.95%). The NOM overall outcome resulted in success in 107 patients (96.4%). NOM was successful in 100% of cases of liver trauma patients and was successful in 94.7% of splenic trauma patients (72/76). NOM failure occurred in 4 patients (5.3%) treated for spleen injuries. All these patients received splenectomy: in 1 case to treat pseudoaneurysm, (AAST, American Association for the Surgery of Trauma, grade of injury II), in 2 cases because of re-bleeding (AAST grade of injury IV) and in the remaining case was necessary to stop monitoring spleen because the patient should undergo to orthopedic procedure to treat pelvis fracture (AAST grade of injury II).Non-operative management for blunt hepatic and splenic lesions in stable or stabilizable patients seems to be the choice of treatment regardless of the grade of lesions according to the AAST Organ Injury Scale.

OBJECTIVE: Aneurysms or dissections can involve multiple aortic segments in patients with Marfan syndrome, requiring staged replacement of the entire aorta. The optimal treatment of descending aortic dissection in these patients is a major challenge. We investigated the feasibility and outcomes of endovascular repair of the descending aorta in patients already submitted to open aortic root/arch surgery. METHODS: From March 1998 to July 2008, 12 patients (10 male and 2 female patients; mean age, 37.8 +/- 11.6 years) affected by Marfan syndrome underwent endovascular treatment for dissection of the descending aorta after previous open aortic root/arch surgery. Stent graft procedures were performed urgently in 5 patients and electively in 7 patients. RESULTS: Neither in-hospital deaths nor perioperative paraplegia or stroke occurred. Follow-up (median, 31 months; range, 3-57 months) was 100% complete. One patient needed surgical conversion for persistent type I endoleak, leading to false lumen expansion 3 months after endovascular repair. Extension of the dissection occurred in 2 patients 1 month and 2 years after the procedure, respectively. No late death or aortic rupture was observed. CONCLUSIONS: Endovascular repair of the dissected descending thoracic aorta can be performed in patients with Marfan syndrome with a low risk of death or major complications. In case of staged procedures, stent graft treatment can be considered a possible alternative to open reoperation. Long-term durability remains to be determined.

BACKGROUND: Coarctation of the aorta accounts for almost 5% of all congenital cardiac malformations, and it is usually treated by open surgical procedures. Despite the excellent primary results, many patients may develop anastomotic pseudo-aneurysms, associated with considerable morbidity and mortality rates. We investigated the role of endovascular repair as an alternative to open re-do surgery on the descending aorta. METHODS: We retrospectively collected data of 11 consecutive patients who presented with pseudo-aneurysms of the descending aorta following previous surgical repair of congenital aortic coarctation. Nine patients developed a pseudo-aneurysm after patch aortoplasty, while an interposition graft repair was performed in two cases. Seven patients underwent an endovascular repair (26.9 years after the previous open surgery). Four patients with a pseudo-aneurysm after coarctation repair associated with arch hypoplasia underwent conventional open re-operation. RESULTS: No complications or death were observed in the conventional surgical group. Technical success was obtained in all patients who received a stent-graft procedure. More than one stent graft was necessary only in one case. A left carotid-left subclavian artery bypass was performed in three patients. Type II endoleak was detected by angiography in one patient who had previously undergone subclavian re-vascularisation. The median follow-up (FU) was 44.5 months and was 100% complete. Neither re-operations nor complications or deaths occurred during FU. CONCLUSIONS: Endovascular repair of pseudo-aneurysms following open surgery for aortic coarctation is feasible and safe. However, more patients and longer follow-up are necessary to assess the efficacy of this promising less-invasive alternative to open re-do surgery.
