“…However, the mean inter-measurement difference of −0.067 ± 0.23 of the oscillometric and Doppler ABI indicated that the automated ABI readings resulted in lower average ABI values. Overall, the authors of this study suggested that this device was more sensitive in recognising already diagnosed PAD cases and less sensitive in establishing new diagnosis of PAD; therefore, the use of this device in primary care would not be recommended [41].…”

Toe–brachial index (TBI) measurement helps to detect peripheral artery disease (PAD) in patients with incompressible ankle arteries due to medial arterial calcification, which is most frequently associated with diabetes. We aimed to evaluate how an automated four-limb blood pressure monitor equipped with TBI measurement could contribute to PAD screening. In 117 patients (mean age 63.2 ± 12.8 years), ankle–brachial index (ABI) measurement was performed using the Doppler-method and the MESI mTablet. TBI was obtained via photoplethysmography (MESI mTablet, SysToe) and a laser Doppler fluxmeter (PeriFlux 5000). Lower limb PAD lesions were evaluated based on vascular imaging. A significant correlation was found between Doppler and MESI ankle–brachial index values (r = 0.672), which was stronger in non-diabetic (r = 0.744) than in diabetic (r = 0.562) patients. At an ABI cut-off of 0.9, Doppler (AUC = 0.888) showed a sensitivity/specificity of 67.1%/97.4%, MESI (AUC 0.891) exhibited a sensitivity/specificity of 57.0%/100%; at a cut-off of 1.0, MESI demonstrated a sensitivity/specificity of 74.7%/94.8%. The TBI values measured using the three devices did not differ significantly (p = 0.33). At a TBI cut-off of 0.7, MESI (AUC = 0.909) revealed a sensitivity/specificity of 92.1%/67.5%. Combining MESI ABI and TBI measurements recognised 92.4% of PAD limbs. Using an ABI cut-off level of 1.0 and sequential TBI measurement increases the sensitivity of the device in detecting PAD. The precise interpretation of the obtained results requires some expertise.

Background/Aim. The best treatment for the occlusion of the largest artery in the thigh is a femorodistal (FD) bypass. Ankle-brachial index (ABI) and multi-detector computed tomographic (MDCT) angiography are the gold standards for diagnosing peripheral arterial occlusive disease. The finite element method can help measure the quantity of blood flow and arterial pressure in the arteries in the leg. The aim of this study was to examine the possibility of using finite element analysis (FEA) method in predicting the outcome of FD bypass surgery. Methods. The research involved 45 patients who were indicated for FD arterial reconstruction from December 1, 2021, to March 31, 2023. MDCT angiography of the arteries of the lower extremities was done pre-operatively and post-operatively in all patients, based on which models were made using the finite element method, for measurement ABI. All patients had their ABI measured pre-operatively and post-operatively using the Doppler ultrasound and sphygmomanometer. Based on the findings of the pre-operative MDCT angiography, a post-operative virtual surgical model was made using the finite element method, for measurement of ABI too. The values of ABI were divided into 5 groups: ABI measured preoperatively (ABI pre-op), ABI measured postperatively (ABI post-op), ABI measured on FEA models based on the MDCT findings [ABI (sim) pre-op], ABI sim post-op, ABI measured on virtual surgery model [ABI sim post-op (virtual)]. The ABI of the models were statistically compared with pre-operative and post-operative measurements done on patients. Results. The values based on the virtual ABI model did not show significant differences compared to the values obtained using Doppler sonography /sphygmomanometer and MDCT angiography (p< 0.001). A strong statistically significant correlation was shown between the virtual ABI and the values obtained by the other two methods (p< 0.001). Conclusion. Virtual simulation based on the MDCT angiography parameters of peripheral blood vessels can be successfully used to predict the immediate outcome of the FD bypass surgery.
