TMPG 1: Dye slowly enters but fails to exit the microvasculature. TMPG 2: Delayed entry and exit of dye from the microvasculature.

EHJ 2002;23:1112-7,血栓分级,Grade 0: No cine-angiographic characteristics of thrombus present. Grade 1: Hazy, possible thrombus present. Angiography demonstrates characteristics such as reduced contrast density, haziness, irregular lesion contour, or a smooth convex “meniscus“ at the site of total occlusion suggestive but not diagnostic of thrombus. Grade 2: Thrombus present small size: Definite thrombus with greatest dimensions less than or equal to 1/2 vessel diameter. Grade 3: Thrombus present moderate size: Definite thrombus but with greatest linear dimension greater than 1/2 but less than 2 vessel diameters. Grade 4: Thrombus present large size: As in Grade 3 but with the largest dimension greater than or equal to 2 vessel diameters. Grade 5: Recent total occlusion, can involve some collateralization but usually does not involve extensive collateralization, tends to have a “beak” shape and a hazy edge or appearance of distinct thrombus. Grade 6: Chronic total occlusion, usually involving extensive collateralization, tends to have distinct, blunt cutoff/edge and will generally clot up to the nearest proximal side branch.,Gibson CM et al. Circulation. 2001;103:2550-2554,Grade 5 thrombus,Grade 4 thrombus,动脉瘤,A localized arterial widening (dilatation) that usually manifests itself as a bulge.

This category is sub-classified using the NHLBI system for grading dissection types: Type A: Radiolucent areas within the coronary lumen during contrast injection, with minimal or no persistence of contrast after dye has cleared. Type B: Parallel tracts or double lumen separated by a radiolucent area during contrast injection, with minimal or no persistence after dye has cleared. Type C: Contrast outside the coronary lumen, with persistence of contrast in the area after dye has cleared. Type D: Spiral luminal filling defects frequently with extensive contrast staining of the vessel. Type E: New persistent filling defects that may be caused by thrombus. Type F: These are non A E dissection types that lead to impaired flow or total occlusion of the coronary artery.,Dissection-Type D,Dissection flap post POBA in a heavily calcified lesion- Type C,其他,穿孔: Presence of extra-luminal contrast that develops during the procedure. 分支丢失: The development of TIMI grade 0 or 1 flow in a side branch that was 1.5 mm in diameter prior to the procedure and was initially patent with TIMI grade 2 or 3 flow. 手术成果: Complete success: If the post-procedure visual residual stenosis is 50% residual stenosis by visual assessment or if TIMI Grade 2 Flow is attained (this includes TFG 2.5). Failure: If there is a persistent total occlusion, if the lesion cannot be crossed, or if there is persistent abrupt closure.,Perforation,Perforation,Pre,Post,其他,远端栓塞: The appearance of an abrupt cutoff in the distal vessel following PTCA. 无复流: Markedly delayed flow down the artery with minimal residual stenosis.,侧枝循环,Partial: Minimal collaterals present.
