经皮球囊扩张治疗下腔静脉节段型完全闭塞综合征

TREATMENT oF SEGMENTAL COMPLETE OBSTRUCT1ON OF INFERIOR VENACAVA BY PERCUTANEoUS BALLooN TRANSLUMINAL ANGIOPLASTY

对５例下腔静脉节段型完全闭塞者，在右心房及下腔静脉双向同时造影基础上，采用房间隔穿刺针穿通闭塞段，１４Ｆ扩张器预扩后，再行经皮腔内血管成形术，术后造影与超声检查见下腔静脉完全闭塞段内径开通至１３．０±２．ｌｍｍ，下腔静脉压力从术前４．５ｌ±１．４８ｋＰａ下降至２．５３±０．７９ｋＰａ，闭塞段远端下腔静脉内径从术前２９．４±１．９ｍｍ减少至２２．１±２．３ｍｍ，症状明显改善，无并发症。对手术方法及可能的并发症进行了讨论。认为此法安全可靠，疗效显著，具有较大的实用和推广价值。

Five cases of Budd-Chlari syndrome were successfully treated by brockenbrough needleand l 4F dilator to puncture the segmental complete obstruction of hepatic inferiOr vena cava(IVC)andsingle balloon。 The average diameter of IVC was increased from 0 mm to l 3.O±2.1 mm。 The averagepressure of IVC dropped from 4. 5l±1. 48 kPa to 2. 53+0. 79 kPa。 None of the patients had serious compiications. This method of treatment and possible complication were discussed. It suggested that PTA maybe a safe ,reliable and practicable treatment for this condition。
