Purpose: To investigate the effect on intrasac pressure of stent-graft deployment within a life-size silicone rubber model of an abdominal aortic aneurysm (AAA) maintained under physiological conditions of pressure and flow. Methods: A commercial bifurcated device with the polyester fabric preclotted with gelatin was deployed in the AAA model. A pump system generated physiological flow. Mean and pulse aortic and intrasac pressures were measured simultaneously using pressure transducers. To simulate a type I endoleak, plastic tubing was placed between the aortic wall and the stent-graft at the proximal anchoring site. Type II endoleak was simulated by means of side branches with set inflow and outflow pressures and perfusion rates. Type IV endoleak was replicated by removal of gelatin from the graft fabric. Results: With no endoleak, the coated graft reduced the mean and pulse sac pressures to negligible values. When a type I endoleak was present, mean sac pressure reached a value similar to mean aortic pressure. When net flow through the sac due to a type II endoleak was present, mean sac pressure was a function of the inlet pressure, while pulse pressure in the sac was dependent on both inlet and outlet pressures. As perfusion rates increased, both mean and pulse sac pressures decreased. When there was no outflow, mean sac pressure was similar to mean aortic pressure. In the presence of both type I and type II endoleaks, mean sac pressure reached mean aortic pressure when the net perfusion rate was low. Conclusions: In vitro studies are useful in gaining an understanding of the impact of different types of endoleaks, in isolation and in combination, on intrasac pressure after aortic stent-graft deployment.

We describe a patient who survived a ruptured abdominal aortic aneurysm without any surgical intervention. The patient had previously had endovascular repair of the aneurysm and surveillance of a stable persistent type II endoleak. This case highlights the difficulties surrounding type II endoleak, its natural history, and the ongoing controversies of its management.

Abstract Background Anastomotic leak after esophagectomy is associated with high levels of morbidity and may impact negatively on oncological outcomes. The aim of this single centre study was to describe our experience in managing these complications Methods From 2007–2017 data was reviewed retrospectively from our prospectively maintained electronic database. All patients underwent either 2 or 3 phase esophagectomy for cancer of the oesophagus or esophago-gastric junction. All histological sub-types and stage of cancer were included in the analysis. Anastomotic leaks were classified according to the Esophagectomy Complications Consensus Group (ECCG) guidelines; type I—conservative management, type II—non-surgical intervention, type III—surgical intervention. Results 224 esophagectomies were included in our analysis (104 (46%) minimally invasive, 120 (54%) open approach). The incidence of all anastomotic leaks was 10% (23/224). Surgical approach did not influence the incidence of anastomotic leak (minimally invasive 10 (43%), open approach 13(57%), P = 0.76). Five patients (22%) had a type I leak, 9 patients (39%) type II and 9 (39%) had a type III leak. There was an increase in the number of leaks managed non-surgically over the last 5 years compared to those in the first five years of our dataset (2012–2017: 11/23 (48%) vs 2007–2012: 4/23 (17%) P = 0.08). The median time for leak diagnosis was 8 days. Most leaks were diagnosed with oral contrast CT 19 (83%). Median hospital stay after anastomotic leak was 58.5 days. Type III leaks were associated with an increased length of stay (median 84 days) compared to type I&II leaks (median (38.5 days) (P = 0.002 95% CI 18.19- 74.41). There was no significant difference in 30-day mortality between type I&II (0 patients) and type III leaks (1 patient) P = 0.260. Conclusion Low mortality rates with anastomotic leak can be achieved. In centres with experienced radiological and endoscopic skills, most anastomotic leaks can be managed non-surgically. Disclosure All authors have declared no conflicts of interest.

Purpose. To study the short-term results of revision knee arthroplasty performed using metaphyseal sleeves. Patients and methods. During the period from 2013 to 2015 the total number of 40 patients was operated on. Type I femoral defects (by AORI classification) were diagnosed in 11 (27.5%), type II - in 26 (65.0%), type III - in 3 (7.5%) cases. Type I tibial defects were diagnosed in 2 (5.0%), type IIa - in 24 (65.0%), type IIb - in 11 (27.0%) and type III - in 3 (7.54%) cases. Metaphyseal femoral sleeves were used in 8 and metaphyseal tibial sleeve - in 40 patients. Results. Follow up period made up from 12 to 43 (mean 32.8) months. Excellent and good results by KSS scale were achieved in 30 (75.0%) of patients, by functional KSS scale - in 24 (60.0%) patients. Mean point by Knee Society Total Knee Arthroplasty Roentgenographic Evaluation scale in patients with femoral and tibial metaphyseal sleeves made up 2.35 versus 0.375 that confirmed the absence of progressive bone resorption. No one case of aseptic instability of the revision implant was observed. Repeated surgical intervention due to reinfection and knee joint contracture with pain syndrome was performed in 2 (5.0%) patients. Conclusion. The obtained data enable to recommend the use of metaphyseal sleeves for revision knee arthroplasty in patients with tibial and femoral defects of types II and III by AORI classification.
