“…It is postulated that by inducing controlled apoptosis on the smooth muscle cells and altering the collagen and extracellular matrix, cryoplasty could potentially change the biomechanics of refractory ureteral strictures 15‐17 . Currently, there are insufficient data to support cryoplasty over plain angioplasty in treatment of peripheral vascular disease 18 . Overall success rate of cryoplasty in our series was not statistically different compared to other treatments, although patients did not have to have an extended course of indwelling stents and had less chance of urinary tract infection or other indwelling stent related complications.…”

The objective of study was to compare clinical outcome of cryoplasty, tandem stents, and cutting balloon ureteroplasty as “bailout procedures” to prevent surgical intervention or stent dependency in renal transplant patients with refractory ureteral stricture. All patients who underwent a bailout procedure from June 11, 2003, to August 8, 2015, at a single institution were reviewed retrospectively. Refractory ureteral stricture was defined as ureteral stenosis not responding to at least two prior percutaneous plain balloon ureteroplasties. Primary patency was defined as stable allograft function following the procedure with unobstructed urine outflow, not requiring indwelling ureteral stent, repeat ureteroplasty, or surgical revision. Sixty‐one procedures were performed on 51 patients. Patients were followed up for a median of 286 days. Overall primary patency rate was 26.1%. Primary patency rate by method was 38.1%, 23.1%, and 14.3% after cryoplasty, tandem stent placement, and cutting balloon dilatation, respectively (P = .260). Primary patency rate was higher in early (<3 months post‐transplant) ureteral strictures (35.7% vs 13.3%; P = .047). More complications identified in patients who had tandem ureteral stents (P = .00754). As some renal transplant patients may not be good operative candidates for ureteral revision, it would be reasonable to attempt one of these “bailout” interventions as long as the clinical team and patient are aware of overall low potential for achieving primary patency.

“…Although various strategies have been proposed as alternative treatments for femoropopliteal ISR, including conventional PTA, cutting balloon, excimer laser, excisional atherectomy, cryoplasty, rotational thrombectomy, and brachytherapy, 1–4,7–11 these have shown high rates of recurrent ISR of 50% to 80% at 1 year. In particular, the patency rate after PTA for femoropopliteal ISR with occlusion is extremely poor (23% at 1 year).…”

“…Initial experience with cryoplasty in the FP arteries suggested modest success with respect to early patency, however, longer term follow-up demonstrated no benefit compared to conventional PTA. [46][47][48][49] Subsequent studies confirmed this lack of benefit, and thus cryoplasty has been largely abandoned for adjunctive treatment in the Ao-I and FP segments.…”

Aorto-iliac (Ao-I) disease is quite prevalent and leads to significant limitation in functional status and quality of life. Advances in endovascular therapy (EVT) techniques in the last 25 years, low risk of periprocedural complications and excellent long-term patency have made it possible to treat most symptomatic patients with Ao-I disease using an endovascular-first rather than a surgical approach in addition to guidelines-directed medical therapy. The approach to intra-procedural assessment of Ao-I lesions has evolved over time to include pressure gradient measurement and intravascular imaging. In 2017, the Society for Cardiovascular Angiography and Interventions (SCAI) published an update to the Appropriate Use Criteria (AUC) for EVT in the Ao-I, femoral-popliteal (FP), infra-popliteal and renal arterial circulations. 1 In 2018, a multi-societal AUC document for EVT was released by the
