中心静脉穿刺置管有多条途径,但唯有颈内静脉标志相对明显操作简单方便,而且血胸、气胸等并发症较锁骨下静脉穿刺少.故是目前在农三师医院采用最多的中心静脉置管途径.农三师医院地处较偏远的基层单位,2007年1月份以来,通过对18例病人应用高位颈内静脉穿刺置管法,发现其具有快速安全、有效的特点. 相似文献

A 63-year-old man with acute myocardial infarction complicated by atrioventricular block underwent an insertion of a temporary electrode for cardiac pacing. The posterior approach for right internal jugular vein cannulation was used. A 15-gauge needle was inserted under the sternocleidomastoid muscle aiming at the suprasternal notch with a 30-degree posterior angle of entry. An hour later the patient started to hiccup. The hiccups were resistant to drug therapy and to cessation of pacing. A chest radiograph revealed elevation of the right diaphragm and hematoma on the right side of the trachea, possibly compressing the right phrenic nerve on its route beneath the sternocleidomastoid muscle and the internal jugular vein. Within seven days the hiccups gradually ceased. Our case shows the advantages and complications of internal jugular vein cannulation. 相似文献

IntroductionAccurate estimation of fluid status is paramount in patients with heart failure. We hypothesized that bedside ultrasound assessment of the internal jugular vein (IJV) and subclavian vein (SCV) could reliably estimate right atrial pressure (RAP).MethodsProspectively enrolled patients were positioned supine. IJV was imaged at the apex of the right sternocleidomastoid muscle and SCV was imaged at the lateral third of the right clavicle. Using M-mode on a portable ultrasound machine, the maximum (Dmax) and minimum (Dmin) anteroposterior diameters were noted during normal breathing. Respiratory variation in diameter (RVD) was calculated as [(Dmax – Dmin)/Dmax] and expressed as percent. Collapsibility was assessed with sniff maneuver. Patients then underwent right heart catheterization and their findings were correlated with above.ResultsTotal of 72 patients were enrolled with mean age 61 years, mean BSA 1.9 m2, and left ventricular ejection fraction 45 ± 20%. Elevated RAP≥ 10 mmHg was associated with dilated IJV Dmax(1.0 vs. 0.7cm, p = 0.001), less RVD with resting respiration (14% vs. 40% for IJV, p = 0.001 and 24% vs. 45% for SCV, p = 0.001), and reduced likelihood of total collapsibility with sniff (16% vs. 66% patients for IJV, p = 0.001 and 25% vs. 57% patients for SCV, p = 0.01). For RAP ≥10 mmHg, lack of IJV complete collapsibility with sniff had a sensitivity of 84% while IJV Dmax > 1cm and RVD <50% had a specificity of 80%.ConclusionThe IJV and SCV diameters and their respiratory variation are reliable in estimating RA pressure. 相似文献

The echocardiographic literature contains very scant reference to incompetence of the valve in the internal jugular vein. However, we found frequent Doppler evidence of such incompetence, especially in patients with congestive failure. This incompetence manifests as a variety of color Doppler and pulsed Doppler patterns, illustrated here in 3 patients. 相似文献

Central vein occlusion (CVO) is not uncommonly observed after hemodialysis (HD) catheter placement and it may prevent subsequent ipsilateral arteriovenous (AV) access creation. Right internal jugular vein catheterization (RJVC) appears to be the insertion site with the lowest incidence of CVO, but little is known about the incidence of CVO following left internal jugular vein catheterization (LJVC). We report on four patients with left innominate vein occlusion after LJVC who developed severe arm swelling after ipsilateral AV access creation. In three of the four cases swelling appeared 12-26 months after access creation, and in the fourth, swelling developed immediately after surgery while the catheter was still in place. Two patients underwent access ligation and in the remainder the arm swelling improved either spontaneously or after LJVC removal. LJVC is not as safe as RJVC as an insertion route for HD catheter placement in terms of CVO frequency. 相似文献

Rationale:Intravenous pyogenic granuloma (IVPG) is a special type of pyogenic granuloma, and its preoperative diagnosis is difficult. We report a rare case of IVPG that develops in the lumen of the internal jugular vein (IJV). Here, we analyze the imaging characteristics of present case and summarize the imaging characteristics of previous reported cases.Patient concerns:A 44-year-old man who presented with a growth in the IJV without any symptoms.Diagnoses:A diagnosis of IVPG was made, based on the pathological examination after surgery.Interventions:The patient underwent surgery to excise the vein segment containing the neoplasm.Outcomes:The patient did not present with any complications in the postoperative follow-up period.Lessons:For clinician, IVPG''s preoperative diagnosis is difficult. Although histopathology remains the gold standard for diagnosis, the combination of multiple types of imaging examinations is necessary to rule out the differential diagnoses of IVPG. 相似文献

目的探讨应用彩色多普勒超声(CDU)检查颅内静脉窦血栓(CVST)患者颈内静脉(IJV)介入治疗的可行性和有效性。方法回顾性纳入12例经CDU诊断,MR静脉成像(MRV)和(或)DSA确诊的13支IJV病变(管腔局限狭窄9例,长段纤细2例,1例为右侧IJV局限性狭窄,左侧IJV长段纤细)并行IJV介入治疗(IJV支架置入5例和球囊扩张7例)的CVST患者。在IJV介入治疗前1周和治疗后1周、6个月、1年、2年应用CDU检查,比较IJV管径及最大血流速度(V_(max))的变化,分析介入治疗的成功率和远期疗效。结果治疗后1周CDU检查显示,13支IJV狭窄部位管径较术前明显增加(4.7±2.1)mm比[(2.3±1.3)mm,t=5.325,P0.01)]。IJV血流速度较术前得到改善[局限性狭窄10支(50±15)cm/s比(87±24)cm/s,t=6.285,P0.01]。对12例中6例(支架置入和球囊扩张各3例)患者进行了平均(18±7)个月的随访,2例球囊扩张术后患者发生了再狭窄。结论对于存在IJV病变的CVST患者,初步观察显示IJV介入治疗可以改善病变管腔及血流动力学,但介入治疗,尤其是球囊扩张术后再狭窄发生率较高。CDU可以作为IJV狭窄病变远期疗效的客观评估手段。 相似文献
