Acquired renal arteriovenous fistula is a rare complication following a nephrectomy and its diagnosis may be made many years after the intervention. The closure of the fistula is advisable in most cases, since it represents a risk for heart failure and rupture of the vessel. There are an increasing number of publications describing different techniques of occlusion. The case of a 70-year-old woman with abdominal discomfort due to a large renal arteriovenous fistula, 45 years after nephrectomy, is presented and current literature is reviewed. Percutaneous embolization was performed by placing an occluding balloon through the draining vein followed by the release of nine coils through arterial access. One day after successful occlusion of the fistula, clinical symptoms disappeared.

Abstract Background Varicocele is an abnormally dilated pampiniform plexus of the veins within the spermatic cord and is considered the most common correctable cause of male factor infertility. Many approaches are described for treatment either surgical (tradition inguinal, subinguinal, and laparoscopic) or non-surgical percutaneous embolization. During the period from August 2017 to December 2018, we prospectively analyzed the preoperative and post-operative alteration of semen parameters (at 3 and 9 months) of the data collected from 63 patients with clinically evident varicocele referred to our tertiary hospital. Patients were divided into two groups: group 1, thirty-three patients who underwent subinguinal microsurgical ligation, and group 2, thirty patients who underwent percutaneous embolization. Results Sixty-three patients enrolled in this study were divided in two groups: group 1, patients who underwent surgery, and group 2, patients who underwent embolization; the mean age is 24.6 ± 1.27 years in group 1 and 23.7 ± 2 years in group 2; there was no statistically significant difference between the two groups as regards BMI, diabetes, hypertension, and smoking. Bilaterality was present in 15.2% of group 1 patients and 10% in group 2 patients (P value 0.06). Most of the patients were classified as grades 2 and 3 with no statistical significance regarding severity of the disease. Preoperative semen parameters for patients including sperm count, motility, and abnormal forms showed no statistically significant difference between the two groups. Post-intervention semen analysis was done twice during follow-up after 3 months and 9 months from the date of intervention. After 3 months, the semen parameters were improved in both groups in spite of the higher sperm count in group 2 but with no statistical significance. After 9 months follow-up, semen analysis showed persistent increase in sperm mobility in group 1 patients in comparison to group 2 patients. Both groups had better improvement in count of normal form with no statistical significant change. Conclusion Improvement of semen parameters while treating primary varicocele by either subinguinal microsurgery approach or percutaneous embolization shows equivalent outcomes.

AbstractA 25-year-old patient presented with bleeding of right pinna arteriovenous malformation (AVM). There was history of ipsilateral external carotid artery (ECA) ligation 10 years back. Subsequent investigations (ultrasound, magnetic resonance imaging, digital subtraction angiography) showed recruitment of complex collaterals from the ipsilateral subclavian artery and vertebral artery feeding the recurrent nidus. The patient underwent two sessions of endovascular embolization and one session of percutaneous embolization. We wish to highlight the feasibility of antegrade embolization in such cases via collaterals and role of direct percutaneous treatment.

Object The resection of spinal hemangiomas is often challenging because of characteristic high-volume and potentially prohibitive intraoperative blood loss. Although transarterial embolization can mitigate this risk, it can be suboptimal when tumor arterial supply is diffuse or poorly defined. The authors present their experience in the use of preoperative percutaneous direct injection of spinal hemangiomas with N-butyl cyanoacrylate (NBCA) as an effective preoperative adjunct that may reduce operative blood loss and facilitate resection of these vascular tumors. Methods Four patients with symptomatic spinal hemangiomas were treated using percutaneous transpedicular direct NBCA-Lipiodol injection; 2 patients had undergone prior spinal angiography, with suboptimal transarterial embolization in 1. Each patient underwent percutaneous bilateral transpedicular NBCA-assisted tumor embolization prior to resection. Retrospective analysis of operative times, blood loss, and clinical data is presented. Results There were no complications associated with the percutaneous NBCA embolization technique. The procedure was effective at facilitating tumor removal and minimizing intraoperative blood loss, especially at the vertebral body resection stage. Improved tumor filling was achieved as the filling characteristics of dilute NBCA-Lipiodol mixture within large-channel, high-flow hemangiomas were appreciated with experience. Conclusions Transpedicular NBCA direct-puncture embolization of spinal hemangiomas is an effective preoperative adjunct that facilitates resection of these highly vascular tumors. It is particularly useful when transarterial embolization is unsafe or suboptimal due to constraints imposed by the local angioarchitecture.
