Objectives Recurrent varicose veins following surgery is a common, complex and costly problem in vascular surgery. Treatment for RVV is technically more difficult to perform and patient satisfaction is poorer than after primary interventions. Nevertheless, traditional vein surgery has largely been replaced by percutaneous office-based procedures, and the patients with recurrent varicose veins have not benefited from the same advantages. In this paper, we propose an endovascular laser treatment that allows reducing the invasiveness and complications in case of SFJ and SPJ reflux after ligation and stripping of the great and small saphenous vein. Methods 8 SFJ and 1 SPJ stumps were treated by endovascular laser treatment in out-patient clinic. Endovascular laser treatment was performed with a 1470 nm diode laser and a 400 µc radial slim™ fiber. Intraoperative ultrasoud was used to guide the fiber position and the delivery of tumescent anesthesia. The gravity of chronic venous disease was determined according to the CEAP classification and the severity of symptoms was scored according to the revised Venous Clinical Severity Score (VCSS). Results The average linear endovenous energy density was 237 J/cm. Patients return to daily activities after a mean of 1.9 days after. The VCSS improved drastically from a mean of 8 pre-interventional to 1 at day 30 and until one year. During the follow-up period (mean 8 months, range: 5–17 months), all the stumps except one were occluded. All patients were very satisfied or satisfied with the method. No severe complications occurred. Conclusions Office-based endovascular laser treatment of groin and popliteal recurrent varicose veins with 1470 nm diode laser and radial-slim fiber is a safe and highly effective option, with a high success rate in the early post-operative period.

In this paper we present our endovascular LASER treatment of mixed shunts. This technique is built according the CHIVA's important principles: diastolic reflux is interrupts at its proximal origin by flush LASER obliteration while centripetal systolic reflux is preserved. In this way, the surgeon interrupts a recirculation pressure loop producing the ambulatory venous hypertension critical to the development of varicose vein symptoms. In this paper we explain how to better understand the intricate venous drainage pathophysiology of mixed shunt and the strategy to approach it using an office-based technique. With the correct strategy and the technological support it is possible to achieve a good functional and aesthetic result to prevent varicosity recurrence. [ABSTRACT FROM AUTHOR]

Background: Endoscopy has been regarded as an effective modality for draining pancreatic collections, pseudocysts, and abscesses. This study analyzes our experience with endoscopic transmural drainage of pancreatic pseudocysts and compares the outcomes in patients with postsurgical and pancreatitis-associated ones. Methods: Patients who underwent endoscopic drainage of a pancreatic pseudocyst from January 1999 through June 2008 were included in this retrospective analysis. The specific indication for attempting the procedure was the presence of direct contact between the pseudocyst and the gastric wall. All the drainages were carried out via a transgastric approach, and one or two straight plastic stents (10 or 11.5 French) were positioned. A comparative analysis of short- and long-term results was made between patients with postoperative pseudocysts (group A) and patients with pancreatitis-associated pseudocysts (group B). Results: Fifty-five patients were included in the study, 25 in group A and 30 in group B. Overall, a single stent was inserted in 84.0% of patients, while two stents were needed in the remaining 16.0%. The technical success rate was 78.2%, whereas procedure-related complications were 16.4%. Complications included pseudocyst superinfection and major bleeding and were managed mainly by surgery. Mortality rate was 1.8% (1 patient). There were no significant differences in the technical success rate and procedure-related complications between the two groups ( p = 0.532 and 0.159, respectively) Recurrences were 13.9% and significantly more common in group B ( p = 0.021). In such cases, a second endoscopic drainage was successfully performed. Conclusion: Transmural endoscopic treatment of pancreatic pseudocysts is feasible and has a technical success rate of 78.2%, without differences related to the pseudocyst etiology. Recurrences, on the other hand, are more common in patients with pancreatitis. Given the severe complications that may occur after the procedure, we recommend that endoscopic drainage be performed in a tertiary-care center with specific expertise in pancreatic surgery.
