The treatment of the critical limb ischemia (CLI) and diabetic foot (DB) is still object of discussion and the gold standard for revascularization has not yet been identified. In these two decades the introduction of endovascular procedures had a large impact on the surgical revascularization and were added to the practice of vascular surgeons in patients who cannot be candidates for a bypass. This may be due to significant comorbidities, a reduced life expectancy, infection or gangrene in the possible sites of distal anastomoses, the unavailability of suitable veins, or the absence of an adequate "landing zone" for the distal part of the bypass. Various studies have evaluated the role of PTA in DF and CLI that resulted favourable in terms of feasibility, technical efficacy, the reduced number of complications, and limb salvage rates. Anyway, long-term patency is better after bypass surgery than after angioplasty, which is burdened by a high restenosis rate. In our experience we tried to practice endovascular approach as a first choice. If the procedure cannot be concluded safely, we continue the intervention surgically or use a hybrid approach. The endovascular-first strategy seems to be the future regardless of comorbidity of the patient and the degree of pathology. The vascular surgeon remains the only specialist that can decide the correct intervention without pressure or been forced and, last but not least, the only one who can independently perform hybrid interventions.

Femoro-popliteal PTA for the treatment of critical limb ischemia is frequently associated with unsatisfactory procedural success rates while directional atherectomy (DCA) has improved success rate since claudicant patients undergoing percutaneous treatment of femoro-popliteal obstructive disease. The aim of this prospective study is to evaluate the safety, efficacy and procedural success of DCA, at one year, in the percutaneous treatment of femoro-popliteal obstructive disease in patients with critical limb ischemia.

Data on efficacy outcomes of endovascular versus surgical revascularization in patients with critical limb ischemia (CLI) in contemporary practice are limited. In this prospective cohort study, 353 consecutive patients with CLI were enrolled and allocated to endovascular (PTA [percutaneous transluminal angioplasty]), surgical (SURG), or no revascularization (No REVASC) after interdisciplinary consensus. Outcome measures were sustained primary clinical success (sPCS; survival without major amputation, repeated target extremity revascularization, and freedom from CLI), limb salvage, and amputation-free survival. Propensity-matched Kaplan-Meier analyses and stratified log-rank tests were performed. The PTA, SURG, and No REVASC groups consisted of 264, 62, and 27 patients, respectively. Compared to SURG patients, PTA patients were significantly older, had more risk factors, and more often had ischemic lesions. Propensity score-adjusted analyses showed no significant differences: sPCS was 51.3%/52.2%, limb salvage rate 91.5%/93.7%, and major amputation-free survival 90.5%/87.2% at 12 months for PTA and SURG, respectively. Amputation-free survival for the No REVASC group was 69% at 12 months. In conclusion, endovascular and surgical revascularization in CLI has comparable efficacy outcomes after 12 months. Contemporary overall outcome of patients with CLI is considerably better compared to earlier studies.

Chronic mesenteric ischemia is a rare and challenging clinical entity with non-specific complaints. It concerns mainly elderly patients with a diffuse atherosclerotic burden affecting other vascular beds. Most surgeons have limited experience with the management of symptomatic occlusive disease of the superior mesenteric artery or coeliac trunk. Last decades, the mesenteric revascularisation debate has also been implicated by the endovascular vogue. An endovascular-first strategy has been adopted in most centres, considering its less invasive character, with lower peri-procedural morbidity and mortality and more rapid recovery. The volume of mesenteric artery stenting has steadily increased over time. However, the long-term results of percutaneous mesenteric angioplasty and stenting are worse than those obtained with open surgery. Currently, many centres reserve open repair for cases in whom PTA failed. This extensive literature review aims to orientate decision-making and choice of revascularisation modality for chronic mesenteric ischemia, considering a significant patient heterogeneity.
