经皮腔内冠状动脉成形术（PTCA）后血管造影结果不理想的重要原因包括弹性反冲、动脉剥离和血栓的存在。虽然血管舒缩性张力的增加可能有助于减少管径的改善，但被动后坐力可能占后者的大部分。通常，在大多数临床系列中[1-4]，在PTCA成功后发现急性狭窄的平均残余直径约为30%，大致对应于50%的管腔横截面积狭窄，可能是这种后坐力的结果。内膜撕裂可能进一步损害明显成功的PTCA手术，即使没有扩大夹层，也会局部破坏层流模式。当血栓与PTCA治疗的病变相关时，经常会遇到不良结果，这可能是由于难以用压力重塑该组织，并且血栓沿管腔表面扩散可能会增加血栓潜在传播部位的数量。
Important causes of suboptimal angiographic results following percutaneous transluminal coronary angioplasty (PTCA) include elastic recoil, arterial dissection, and the presence of thrombus. Although increased vasomotor tone may contribute to a reduction of luminal diameter improvement, passive recoil probably accounts for most of the latter. Typically, in most clinical series [1–4] a mean residual diameter of acute stenosis of approximately 30%, which roughly corresponds to a 50% luminal cross-sectional area stenosis, is found after successful PTCA, presumably as a result of such recoil. Intimal tears may further compromise an apparently successful PTCA procedure, even without propagation of a dissection, by local disruption of laminar flow patterns. When thrombus is associated with a lesion treated with PTCA, a poor result is frequently encountered, perhaps as a result of the difficulty in attempting to remodel this tissue with pressure and the possibility that spreading the thrombus along the luminal surface may increase the number of sites of potential propagation of the thrombus.
