“…The prevalence of peripheral vascular disease in the general population varies from 12 to 14%, affecting up to 20% of those patients older than 70 years. [1][2][3][4][5][6] Magnetic resonance angiography (MRA) of abdomen, pelvis and lower extremity is a common method to identify vascular pathologies of the aorta and peripheral arteries. There are several advantages of using MRA as a non-invasive, accurate three-dimensional (3D) diagnostic method without radiation in comparison to interventional, digital subtraction angiography (DSA) or computed tomography angiography (CTA).…”

“…There are several advantages of using MRA as a non-invasive, accurate three-dimensional (3D) diagnostic method without radiation in comparison to interventional, digital subtraction angiography (DSA) or computed tomography angiography (CTA). [1][2][3][4][5] MRA has become one of the primarily used imaging modalities for the assessment of aortic and peripheral arterial disease. 7 In addition to precise characterization of vascular anatomy, MRA examinations do also include portions of the abdomen, pelvis and lower extremity, underlining the potential to incidentally detect clinically relevant extravascular findings.…”

Background The aim of this study was to assess the prevalence and clinical significance of extra-vascular findings in patients undergoing magnetic resonance angiography of the abdomen, pelvis and lower extremities. Materials and methods Three hundred fifty-two patients underwent abdominal, pelvic and lower extremity 1.5 T magnetic resonance angiography. Clinically relevant vascular and extra-vascular findings were identified. Relevant vascular findings were classified as stenosis, occlusion, aneurysm, sclerosis, dissection or vasculitis. Relevant extra-vascular findings were categorized as 'safe' (Group A), intermediate - requiring additional investigation - (Group B) and malignant/endangering - requiring change of therapy (Group C). Results A total of 2152 clinically relevant vascular findings was identified (6.1/patient). The most frequent vascular finding was femoral artery stenosis (10.6%). Four hundred fifty-one extra-vascular findings were observed (1.3/patient) and classified into Group A (78%), Group B (19.5%) and Group C findings (2.4%). The most frequent malignant findings were lung cancer, lymphoma, osteosarcoma, hepatocellular carcinoma and renal cell carcinoma (7/352 patients). Conclusions Extravascular findings are frequently encountered in magnetic resonance angiography performed for vascular indications. Clinically relevant findings are seen in a substantial part of patients and should prompt further diagnostic work-up.

Mostly low- and very low-quality evidence suggests no clear differences between different stem cell sources and different treatment regimens of autologous cell implantation for outcomes such as all-cause mortality, amputation rate, ulcer healing, and rest pain for 'no-option' CLI patients. Pooled analyses did not show a clear difference in clinical outcomes whether cells were administered via IM or IA routes. High-quality evidence is lacking; therefore the efficacy and long-term safety of autologous cells derived from different sources, prepared using different protocols, administered at different doses, and delivered via different routes for the treatment of 'no-option' CLI patients, remain to be confirmed.Future RCTs with larger numbers of participants are needed to determine the efficacy of cell-based therapy for CLI patients, along with the optimal cell source, phenotype, dose, and route of implantation. Longer follow-up is needed to confirm the durability of angiogenic potential and the long-term safety of cell-based therapy.
