Semiquantitative assessment of lower limb atherosclerosis from routine angiographic images

Markers of vascular inflammation are associated with the extent of atherosclerosis assessed as angiographic score and treadmill walking distances in patients with peripheral arterial occlusive disease

“…There are different reports regarding angiographic scoring systems other than the one we used in our study, described by Bollinger et al 45 and Scott et al 46 However, to our knowledge, no reports have demonstrated any angiographic scoring system better suited to serve the purpose of the present study than the one we used. We also chose to use a single-stage treadmill with a fixed grade of 10°instead of a progressive, multiple-stage treadmill in our investigations.…”

Paramalleolar Arterial Bollinger Score in the Era of Diabetes and End-Stage Renal Disease – Usefulness for Predicting Operative Outcome of Critical Limb Ischemia –

“…PBS in the New Era according to the original scoring method. 23 PBS was defined as the sum of the scores for each of the 4 target arteries (maximum, 60; minimum, 0; Figure 1). PBS threshold for differentiating postoperative outcome was arbitrarily defined as >45, which is clinically equivalent to severe occlusive lesions in 4 of the 3 arteries of the paramalleolar segment, and stenosis or occlusion in the other artery.…”

“…PBS in the New Era was used to divide lower extremity arteries into several segments, and analyze various patterns of occlusions and stenosis on angiography. 23 This system was adopted as the method for postoperative assessment in the BASIL trial and was also adapted for nationwide registration of CLI patient data in Japan. In the BASIL trial, mean below-knee Bollinger angiography score was an independent risk factor for both time to death after operation and AFS.…”

“…In the original paper by Bollinger et al, arterial segments were defined as ranging from the abdominal aorta to the anterior/posterior tibial arteries and peroneal artery, which did not include the foot region. 23 Given that loss of pedal arch quality is the main culprit lesion in patients with DM and ESRD, and that it is directly related to postoperative outcome after bypass surgery, we consider that evaluation of the plantar arch is as important as of other arteries. 24- 27 We extended the definition of arterial segments to a more peripheral level and defined the paramalleolar segment as the distal half of the anterior/posterior tibial artery, peroneal artery and plantar arch.…”

Ischemic Ulcer Healing: Does Appropriate Flow Reconstruction Stand for All That We Need?

“…Owning the Bollinger angiographic scale [50], the Trans-Atlantic Inter-Society initial Consensus (TASC I and II) [3,51], the Rutherford staging of PAD [52], and the European recommendations for CLI management [53], complementary definitions yet adding only TcPO 2 microcirculatory references were settled [27,47,53].…”
