First Line Treatment

Congenital renal artery aneurysm is uncommon. Moreover, renal artery aneurysm concomitant with a congenital renal arteriovenous fistula is extremely rare. Transarterial embolization is the first-line treatment for these conditions. We report a case of a patient with congenital renal artery aneurysm concomitant with a congenital renal arteriovenous fistula of the upper polar left renal artery which was successfully treated by transarterial embolization with coil, glue, and Amplatzer vascular plug.

AbstractIntrinsically radiopaque (imageable) microspheres for transarterial embolization (TAE) are required to enable real-time intraprocedural feedback and definition of spatial distribution patterns of embolic materials in target tissues. This pilot study evaluates acute and sub-chronic safety and efficacy of imageable zinc-silicate (Zn-Si) glass microspheres in a swine renal artery embolization (RAE) model. Eight swine were divided into two cohorts. Clinical determinants of embolization effectiveness, including imageability, deliverability and temporal/ spatial distribution of microspheres in target tissues were assessed. Subsequently, cohort I and II were used to evaluate the acute and subchronic host response against the Zn-Si microspheres versus a clinical control. The developed microspheres provide for direct intraprocedural feedback using standard diagnostic imaging techniques. Fluoroscopy correlated with ex-vivo high-resolution radiography, CT and micro-CT, demonstrating high imageability, excellent spatial distribution and packing of the Zn- Si microspheres. At follow-up, infarction of the embolized kidneys was noted without any major adverse tissue reaction. Mild recanalization was observed microscopically for both experimental and control microspheres. Zn-Si microspheres permit the definition of spatial distribution in a target tissue, consequently permitting the optimization, personalization and improvement of TAE techniques.

Abstract Purpose To retrospectively evaluate the mid-term outcome of transarterial embolization (TAE) of renal artery pseudoaneurysm (RAP) including arteriovenous fistula (AVF) after partial nephrectomy screened by early postoperative contrast-enhanced CT (CE-CT). Materials and methods Eighty-two patients (7.0%) who underwent TAE after partial nephrectomy were reviewed, from 1166 partial nephrectomies performed over 6 years. In 18 patients (22.0%), TAE was performed emergently on the median postoperative day (POD) seven. In the remaining patients, elective TAE was performed on the median POD six for RAP detected by early postoperative CE-CT or that emerged on follow-up CE-CT. Results In one patient (1.2%), TAE was performed twice because one of two RAPs could not be embolized during the first TAE, being successfully embolized at the second TAE after readmission with hematuria. Otherwise, no bleeding recurrence or RAPs were observed during the median 1354 follow-up days. Thus, the primary and secondary success rates of TAE were 98.8% (81 of 82 patients) and 100% (82 of 82 patients), respectively. On angiography, the average number of lesions was 1.7 ± 0.9 and the average RAP size was 12.8 ± 6.0 mm. The shapes of the lesions varied: oval-round 60, oval-round + AVF 36, irregular + AVF 14, AVF 12, irregular 10, disruption 4, and extravasation 3. No major complications were observed. The median inpatient days after TAE were two. No estimated glomerular filtration rate deterioration was observed (64.6 ± 18.6 vs. 64.2 ± 18.4 mL/min/1.73 m2, p = 0.902). Conclusion TAE is largely effective and safe for treating bleedings or RAPs, including AVFs, after partial nephrectomy, as screened by early postoperative CE-CT.

Introduction: Iatrogenic injuries are the most common (>50%) cause of renal vascular lesions and most of these vascular lesions resolve spontaneously, however, surgical or percutaneous treatment is recommended when there is massive bleeding, renal hemorrhage persisting for more than 72 hours, or progressively deteriorating renal functions. Renal artery embolization is considered safe, effective as well as less invasive as the alternative treatment method is emergent nephrectomy or clamping of the renal artery which results in the loss of the kidney. We conducted a study to describe the efficacy of transarterial embolization in the management of post-traumatic hematuria. Methods: Retrospective review of 30 patients from April 2013 to July 2017 who underwent transarterial embolization for renal vascular lesions following blunt and iatrogenic renal injuries was done. Type of renal vascular lesions, the angiographic status of visualized vascular lesions immediately following embolization, and post-procedural status of hematuria were evaluated. Results: Thirty patients with a mean age of 35.3 years were included in the study.  Twenty-two patients with pseudoaneurysm and eight with arteriovenous fistula in the kidney underwent transarterial embolization. Selective embolization was done in 28 out of 30 patients with complete resolution of hematuria. Two patients underwent non-selective embolization of the main renal artery which was necessary for control of hematuria.   Conclusions: Transarterial embolization is a highly effective technique in the management of traumatic renal vascular lesions presenting with left threatening or continuous hematuria.
