Abstract
This study examined the impact of IVC stent placement across the renal veins on renal function and renal vein patency. The study cohort consisted of 48 patients who underwent IVC stent placement across the renal veins ("RV+ group") and 96 patients who underwent IVC stent placement sparing the renal veins ("RV- group"). Changes in eGFR (RV+ vs RV-, mL/min/1.73 m2) at 1-7 days (-0.8 vs. -0.7, P = 0.98), 8-30 days (1.9 vs. 0, P = 0.66), 31-180 days (0.3 vs. -2.1, P = 0.55), and beyond 180 days (5.8 vs. -1.9, P = 0.06) from IVC stent placement were similar between the two groups. There was one instance of renal vein thrombosis in the RV+ group (2%) after a mean follow-up of 4.3 ± 3.1 years. In conclusion, IVC stent placement across the renal veins does not significantly impact renal function and rarely results in renal vein thrombosis.
本研究探讨经肾静脉置入静脉内腔支架对肾功能和肾静脉通畅的影响。研究队列包括48例经肾静脉内腔静脉支架置入术患者（RV+组）和96例保留肾静脉内腔静脉支架置入术患者（RV-组）。两组IVC支架置入后1-7天（-0.8 vs -0.7, P = 0.98）、8-30天（1.9 vs. 0, P = 0.66）、31-180天（0.3 vs. -2.1, P = 0.55）和180天后（5.8 vs. -1.9, P = 0.06） eGFR （RV+ vs. RV-, mL/min/1.73 m2）的变化相似。RV+组平均随访4.3±3.1年，出现1例肾静脉血栓（2%）。综上所述，经肾静脉置入IVC支架对肾功能无明显影响，且极少导致肾静脉血栓形成。
期刊介绍：
JVIR, published continuously since 1990, is an international, monthly peer-reviewed interventional radiology journal. As the official journal of the Society of Interventional Radiology, JVIR is the peer-reviewed journal of choice for interventional radiologists, radiologists, cardiologists, vascular surgeons, neurosurgeons, and other clinicians who seek current and reliable information on every aspect of vascular and interventional radiology. Each issue of JVIR covers critical and cutting-edge medical minimally invasive, clinical, basic research, radiological, pathological, and socioeconomic issues of importance to the field.
