目的 :研究经股浅动脉植入介入药盒 (PCS)的可行性。方法 :①患者 60例 ,无栓塞适应证的原发性肝癌 3 6例、转移性肝癌 14例、其它晚期肿瘤 10例 ,均经股浅动脉植入PCS ,泵导管远端置于相应靶血管 5 0例 ,10例置于胸或腹主动脉 ;②杂种犬 2只 ,采用Seldinger技术经股动脉置入PCS导管至主动脉。观察指标 :①临床体征 ;②泵导管远端位置、形态及与体位关系 ,靶血管及植入侧股动脉形态 ;③PCS植入前、后股动脉血流动力学变化 ;④狗PCS植入侧股动脉病理学改变。结果 :导管到位率 95 % ,植入侧下肢及局部无异常。植入侧股动脉无狭窄。无明显血流动力学改变。靶血管闭塞3 .3 % ,PCS导管移位 8.3 % ,PCS导管远端位于主动脉者无导管下移。移位者其导管远端均不同程度缓慢下移。结论 :经股浅动脉化疗泵植入术安全可行 ,熟练的植入泵技术可避免或减少并发症 ,主动脉内泵导管远端是否下坠与体位无关 ,主要取决于血管、血液生物物理学特性及泵导管远端形态。
Objective: To study the feasibility of transplanted superficial femoral artery into PCS. Methods: ① There were 60 patients with 36 cases of primary liver cancer without embolism indications, 14 cases with metastatic liver cancer and 10 cases with other advanced tumors. The PCS was implanted through the superficial femoral artery and the distal end of the pump catheter was placed on the corresponding target vessel 50 cases, 10 cases were placed in the thoracic or abdominal aorta; ② two canine dogs, using Seldinger technology PCS catheter into the aorta via the femoral artery. Observe the indicators: ① clinical signs; ② distal catheter position, shape and posture, target vessel and femoral artery morphology; ③PCS before and after the femoral artery hemodynamic changes; ④ PCS PCS implantation Femoral artery pathology changes. Results: The catheter placement rate was 95%. There was no abnormality in the lower extremities and the local implantation. There was no stenosis in the femoral artery. No significant hemodynamic changes. Target vessel occlusion was 3.3%, and PCS catheter displacement was 8.3%. The distal end of PCS catheter was located in the aorta without catheter down. Displacement of its distal catheter are slowly down to varying degrees. Conclusions: Transfected superficial femoral artery pump is safe and feasible. The skilled implant pump technique can avoid or reduce the complications. Whether the distal end of the intra-aortic pump tube falls or not depends on the biophysical characteristics of blood vessels and blood And pump catheter distal form.
