“…The present values for the diameter of the femoral arteries were 9.0 ± 0.7 mm in the LFA and 9.1 ± 0.7 mm in the RFA (Table 3), which is in the same range as the previously reported values of 7.5 ± 0.3 mm measured using angiography [30] and 8.1 ± 0.11 mm measured by Duplex Doppler [31]. In the present review, cross-sectional area of the femoral arteries was 0.65 ± 0.1 cm 2 in the LFA and 0.65 ± 0.11 cm 2 in the RFA.…”

Non-invasive measurement of splanchnic hemodynamics has been utilized in the clinical setting for diagnosis of gastro-intestinal disease, and for determining reserve blood flow (BF) distribution. However, previous studies that measured BF in a "single vessel with small size volume", such as the superior mesenteric and coeliac arteries, were concerned solely with the target organ in the gastrointestinal area, and therefore evaluation of alterations in these single arterial BFs under various states was sometimes limited to "small blood volumes", even though there was a relatively large change in flow. BF in the lower abdomen (BFAb) is potentially a useful indicator of the influence of comprehensive BF redistribution in cardiovascular and hepato-gastrointestinal disease, in the postprandial period, and in relation to physical exercise. BFAb can be determined theoretically using Doppler ultrasound by subtracting BF in the bilateral proximal femoral arteries (FAs) from BF in the upper abdominal aorta (Ao) above the coeliac trunk. Prior to acceptance of this method of determining a true BFAb value, it is necessary to obtain validated normal physiological data that represent the hemodynamic relationship between the three arteries. In determining BFAb, relative reliability was acceptably high (range in intra-class correlation coefficient: 0.85-0.97) for three arterial hemodynamic parameters (blood velocity, vessel diameter, and BF) in three repeated measurements obtained over three different days. Bland-Altman analysis of the three repeated measurements revealed that day-to-day physiological variation (potentially including measurement error) was within the acceptable minimum range (95% of confidence interval), calculated as the difference in hemodynamics between two measurements. Mean BF (ml/min) was 2951 ± 767 in Ao, 316 ± 97 in left FA, 313 ± 83 in right FA, and 2323 ± 703 in BFAb, which is in agreement with a previous study that measured the sum of BF in the major part of the coeliac, mesenteric, and renal arteries. This review presents the methodological concept that underlies BFAb, and aspects of its day-to-day relative reliability in terms of the hemodynamics of the three target arteries, relationship with body surface area, respiratory effects, and potential clinical usefulness and application, in relation to data previously reported in original dedicated research.

“…It is of interest to compare these results with studies of blood flow in arteriomegalic pelvic and leg vessels (Callum et al, 1974) which showed no difference between normal and arteriomegalic patients. The velocity of blood in the arteriomegalic group was reduced.…”

“…PAA is defined as having a minimal vessel diameter of 1.2 cm and is at least 1.5 times the diameter of the proximal arterial segment. 16 All other arterial aneurysms are defined as being 1.5 times the diameter of the proximal adjacent segment. The mean rate of growth in aneurysms less than 20 mm in diameter is 1.5 mm/yr, 3.0 mm/yr at sizes 20 to 30 mm, and 3.7 mm/yr at sizes greater than 30 mm.…”

Update on the Diagnosis and Management of Popliteal Aneurysm and Literature Review

et al. 2006

Popliteal artery aneurysms (PAAs) are the most frequent peripheral aneurysm with a significant morbidity if left untreated. Open surgical technique is still considered the gold standard; however the revolution in endovascular repair has proven to be a valid alternative option in selected patients. The role of endovascular treatment in PAA is still considered in its infancy. In addition, the indications for use of endovascular stents as compared to standard open surgery have not yet been fully defined and more studies are warranted to characterize the durability of this technique. This article describes the general principles of the natural history, clinical presentation, and long-term limb salvage and survival outcomes for patients with such aneurysms. It also details the features and results for the devices in current use and highlights the current consensus in the management of PAA.
