ABSTRACT
Objective:To systematically evaluate the risk factors of implantable venous access port-related bloodstream infections and provide basis for prevention of catheter-related bloodstream infection in tumor patients.Methods:The Cochrane Library, PubMed, EMBASE, Web of science, CNKI, Wanfang database, VIP database, CBM, Chinese and English Clinical trials Registry (ChiCTR) were searched to collect the literature on risk factors for implantable venous access port-related bloodstream infections in tumor patients from the establishment of the database to April 2022. Two evaluators independently screened and extracted the obtained literature according to the inclusion and exclusion criteria, and used the Newcastle-Ottawa Scale for quality evaluation. Meta-analysis was conducted by RevMan 5.3 software and Stata SE/MP(14.0 version).Results:A total of 13 studies were included, including 23 related risk factors. Among them, prolonged use of catheters, palliative treatment, hematological tumors, neutropenia, hospitalized patients, and chemotherapy were risk factors for implantable venous access port-related bloodstream infections in tumor patients, with statistically significant differences ( OR values ranging from 0.26 to 8.77, all P<0.05). Conclusions:The long time of catheter use, palliative treatment, hematological tumor, neutropenia and chemotherapy were the risk factors of implantable venous access port-related bloodstream infection in patients with tumor, Medical personnel should make a good assessment and strengthen health education to minimize the chances of infection and effectively reduce the incidence of infection related to the infusion port.
ABSTRACT
OBJECTIVE To compare the safety of high-dose methotrexate （HD-MTX） via peripherally inserted central catheter （PICC） and totally implantable venous access port （TIVAP） in pediatric patients with malignant brain tumors. METHODS Patients with malignant brain tumors who received HD-MTX via PICCs or TIVAPs in our hospital from July 2018 to April 2022 were retrospectively analyzed. Clinical data were collected to compare differences in blood concentration of methotrexate （MTX），the incidence of adverse events （including adverse drug reactions and catheter-related complications） and length of stay in hospital. Multivariate linear regression was applied to analyze the factors that influenced the blood concentration of MTX. RESULTS A total of 107 patients were included in the study，with 65 patients in the PICC group and 42 patients in the TIVAP group. Blood concentration of MTX at 24 h （C24 h） in TIVAP group was significantly higher than PICC group （[ 126.87±61.99） μmol/L vs. （102.45±48.77） μmol/L，P＜0.05）. There was no significant difference in blood concentration of MTX at 42 h （C42 h），compared with PICC group （P＞0.05）. Results of multivariate linear regression analysis showed that TIVAP was associated with the increase of C24 h（P＜0.05）. No significant differences were observed in the incidence of adverse events and the length of stay in the hospital between 2 groups （P＞0.05）. CONCLUSIONS Risk of adverse events is not increased，although the MTX C24 h level is elevated after administration of TIVAP. TIVAP is a safe choice for HD-MTX therapy with implementing therapeutic drug monitoring.
ABSTRACT
RESUMEN La fractura y embolización de un catéter implantable con reservorio es una complicación infrecuente, pero potencialmente grave. El síndrome pinch-off fue descripto en los accesos venosos subclavios, cuando la sección del catéter se produce por la compresión intermitente entre la primera costilla y la clavícula. Informamos el caso de una paciente oncológica a quien se le colocó un catéter implantable con reservorio por acceso percutáneo ecoguiado y control radioscópico en la vena subclavia. Luego de varias sesiones de quimioterapia comenzó con mal funcionamiento del catéter; la radiografía de tórax evidenció la fractura completa del catéter a nivel del espacio costoclavicular con embolia de un fragmento a las cavidades cardíacas. Se realizó la extracción endovascular del catéter fracturado me diante lazo de nitinol por acceso percutáneo femoral, sin complicaciones. Se analizan la incidencia, los factores de riesgo y las medidas para prevenir el síndrome de pinch- off en los catéteres implantables con reservorio.
ABSTRACT Fracture and migration of totally implantable venous access devices is a rare but potentially serious complication. Pinch-off syndrome was described in subclavian venous accesses when the intermittent compression of the catheter between the first rib and the clavicle produces catheter fracture. The report the case of a patient with cancer who underwent implantation of a totally implantable venous access device through the subclavian vein under ultrasound and radioscopy guidance. After several cycles of chemotherapy, the patient started with malfunctioning of the device. The chest X-ray showed a complete fracture of the catheter at the level of the costoclavicular space with migration of a fragment of the catheter to the right cardiac chambers. The fractured catheter was percutaneously removed via the right femoral vein using nitinol gooseneck snare without complications. The incidence of the pinch-off syndrome, risk factors and prevention measures in totally implantable venous access devices are analyzed.

ABSTRACT
Objective To evaluate the technical feasibility and safety of a single-incision technique via axillary vein (AV) for placement of totally implantable venous access port (TIVAP) guided by ultrasound combined with DSA in clinical application. Methods We retrospectively analyzed clinical data of 240 patients who received TIVAP by single incision technique via AV access guided by ultrasound combined with DSA. We observed and recorded operation-related information such as AV width, AV puncture success rate, implantation success rate, ultrasound-guided puncture time, operation time and intraoperative and postoperative complications, etc. Results All 240 patients were successfully implanted with TIVAP, and the success rate was 100%. In 229 cases, TIVAP was implanted through single-incision AV puncture under the guidance of ultrasound combined with DSA, and the success rate of AV puncture was 95.42% (229/240). In 11 cases, TIVAP was implanted through the ipsilateral internal jugular vein (IJV) under the guidance of ultrasound combined with DSA due to the failure of AV puncture. In the 240 patients, the average width of AV of the intended puncture segment was (7.56±1.26) mm measured by preoperative ultrasound exploration and positioning, in which 195 cases were successfully punctured once, 26 cases were successfully punctured twice, and 8 cases were successfully punctured three times, with the success rate of 81.25%, 10.83% and 3.34%, respectively. The average puncture time under ultrasound guidance was (0.85±0.52) min, and the average operation time was (25.9±4.8) min. The incidence of intraoperative complications was 1.67% (4/240). No hemothorax, hemopneumothorax or serious fatal complications occurred. The incidence of complications during TIVAP retention was 2.92% (7/240). No complication such as catheter-related bloodstream infection, catheter-related venous thrombosis, catheter rupture/displacement, clipping syndrome or drug extravasation was observed. Conclusion Ultrasound combined with DSA guided single-incision technique via AV access in the implantation of TIVAP is a feasible and safe implantation method with high technical success rate, short operation time and low risk of complications. It can be used as another choice of TIVAP implantation method.
ABSTRACT
Objective: To observe movement of catheter tip of chest wall access port implanted via the internal jugular vein and impact factors when changing from supine to vertical positions. Methods: Data of 171 patients underwent implantation of chest wall access port via the internal jugular vein and chest X-ray films on supine and vertical position postoperatively were retrospectively analyzed, and the distance from the tracheal protuberance to catheter tip was measured. Pearson correlation analysis and multivariate regression analysis were performed to observe the impact factors of moving distance of catheter tip. Results: Changing from supine to vertical position, the catheter tip was inclined to cephalad movement, and the mean moving distance was (15.82±16.87)mm. The distance of catheter tip movement was positively correlated with gender (P=0.039) and sebum thickness (P=0.011) and negatively correlated with indwelling length of catheter (P=0.039). Conclusion: The catheter tip of chest wall access port implanted via the internal jugular vein tends to shift cephalad when changing from supine to vertical position, and the distance of movement is related to patient's gender, sebaceous thickness and the length of indwelling catheter.
ABSTRACT
OBJECTIVE: To explore the clinical application of the peripheral totally implantable venous access port(TIVAP) in breast cancer chemotherapy patients,and to understand the clinical applicability and safety of peripheral TIVAP.METHODS: The clinical data of 201 cases using peripheral TIVAP of multi-course chemotherapy in the First Affiliated Hospital of Chongqing Medical University from March 2017 to June 2018 were analyzed retrospectively.The difference of composition ratio of various complications,and difference between the conventional pressure bandaging method and the modified pressure bandaging method for incision hemorrhage,the conventional implantation method and the improved implantation method for catheter ectopic and the difference of the catheter ectopic after left/right peripheral vein TIVAP placement were compared.RESULTS: There were 50 cases(24.9%) of postoperative complications,15 cases(7.5%) of incision hemorrhage,4 cases(2.0%)of catheter-related thrombosis,3 cases(1.5%) of base exposure,4 cases(2.0%) of sack infection,15 cases(7.5%)of primary catheter ectopic,7 cases(3.5%) with no blood withdrawal,2 cases(1.0%) with catheter-related upper limb movement limitation.Using the goodness of fit test(equal ratio) to compare the composition ratio of various complications,χ~2=30.520,P<0.001,the proportion of complications was not obeyed,and the proportion of incision hemorrhage and catheter ectopic was the highest.The conventional pressure bandaging method(78 cases) and the modified pressure bandaging method(123 cases) showed incision bleeding,and the difference was statistically significant [11 cases(14.1%) vs.4 cases(3.3%),χ~2=6.642,P=0.010];the conventional implantation method(90 cases) and the modified implantation method(121 cases) were compared with catheter ectopic,and the difference was statistically significant [9 cases(10.0%) vs.3 cases(2.4%) χ~2=4.131,P=0.042];there was no statistically significant difference in catheter ectopic position after left(106 cases)/right(95 cases) peripheral TIVAP implantation [8 cases(7.5%) vs.7 cases(7.3%),χ~2=0.020,P=0.962].CONCLUSION: The complication of peripheral TIVAP can be effectively controlled through safe management,close observation and active treatment.TIVAP is still a safe and effective intravenous infusion channel for long-term clinical use if there is no contraindication.
ABSTRACT
Objective To discuss the effect of body posture change on the catheter tip position of totally implantable venous access port (TIVAP).Methods Under ultrasound guidance,implantation of TIVAP was carried out through bedside puncturing of internal jugular vein or subclavian vein.After the implantation of TIVAP,X-ray chest films of both erect position and supine position were taken to check the catheter tip position.The distance from the upper edge of the first thoracic vertebra to the catheter tip was separately measured on the erect position and supine position chest films.The shift of the catheter tip position was judged by the difference in the distance measured on chest films as well as by the comparison with the bony anatomic marks.Results Successful implantation of TIVAP was accomplished in 86 patients.When the patients changed from erect position to supine position,the catheter tip of TIVAP moved caudally in 71 patients,with the mean displace distance being (12.29±7.48) mm;the catheter tip of TIVAP moved cephalad in 31 patients,with the mean displace distance being (5.00±3.79) mm;and the catheter tip of TIVAP remained in the same position in 2 patients.When the patients changed from erect position to supine position,the catheter tip of TIVAP had a tendency to move toward the foot side,the average displace distance was (-9.32±9.36) mm,the difference in catheter tip location between two photographic positions was statistically significant (P＜0.000 1).No statistically significant correlation existed between the changes of catheter tip position and the sex,age,height,weight as well as body mass index (P＞0.05).Conclusion After the implantation of TIVAP,the position of catheter tip will change with patient's body posture.When patient's posture changes from erect position to supine position the tip of the catheter tends to shift towards the atrium.
ABSTRACT
Objective To evaluate the clinical application of implantation of totally implantable venous access port (TIVAP) via the internal jugular vein (IJV) guided by ultrasonography in infants.Methods The clinical data of 446 sick infants,who received TIVAP at the Affiliated Shanghai Children's Medical Center,School of Medicine,Shanghai Jiaotong University,China (single center) during the period from January 2009 to July 2016,were retrospectively analyzed.The time spent on surgery,the success rate of first puncturing of IJV and the incidence of puncture-related complications were recorded,and the results were compared between traditional IJV blind puncture group and ultrasound-guided IJV puncture group.Results Of the 446 sick infants,traditional IJV blind puncture was employed in 265 and ultrasound-guided IJV puncture was adopted in 181.In traditional IJV blind puncture group,the mean time spent on surgery was 7.6 min,the success rate of first puncturing of IJV was 75.85％ (201/265),and the incidence of puncturerelated complications was 5.66％ (15/265).In ultrasound-guided IJV puncture group,the mean time spent on surgery was 4.2 min,the success rate of first puncturing of IJV was 97.24％(176/181),and the incidence of puncture-related complications was 1.70％ (3/181).Conclusion For the performance of TIVAP implantation in sick infants,the use of ultrasound-guided IJV puncture technique can shorten the operation time,improve the success rate of first puncturing,and reduce the incidence of puncture-related complications.Therefore,ultrasound-guided IJV puncture is a safe,effective,simple and feasible technique.This technique is worthy of clinical promotion.
ABSTRACT
Objective To evaluate the feasibility and safety of embedding the totally implantable venous access port (TIVAP) via the access of right brachiocephalic vein (BCV).Methods The clinical data of 493 patients,who underwent the placement of TIVAP by using right BCV route during the period from March 2013 to December 2015,were retrospectively analyzed.The patients included 137 males and 356 females,with a mean age of (47.3±13.2) years old (ranging from 29 to 78 years old).The puncture success rate and TIVAP indwelling procedure-related complications were analyzed.Results The technical success rate was 100％,the success rate of initial puncturing was 99％ (488/493).The mean operation time was (22.5± 8.3) minutes (range of 18-35 minutes).Mis-puncturing of artery happened in 3 patients (0.61％,3/493);and no severe complications such as hemothorax or pneumothorax occurred.After implantation,the patients carried TIVAP for 124-986 days,with a mean of (271.1±53.8) days.The incidence of complications was 2.25％ (11/488),including hemorrhage at port site (n=2),catheter-related infection (n=l),partial thrombosis (n=2),and formation of fibrous protein sheath (n=6).No serious complications such as displacement or rupture of catheter,or catheter pinch-off syndrome (POS),etc.were observed.Conclusion The implantation of TIVAP by using right BCV route has high puncturing success rate,the technique is safe and reliable,and it can provide another option of catheter access for the clinical performance of TIVAP implantation.
ABSTRACT
Objective·To investigate the incidence, risk factors and treatment of the catheter-related thrombosis (CRT) in breast cancer patients after implantation of totally implantable venous access port (TIVAP) in chemotherapy. Methods·A total of 190 cases after implantation of TIVAP were investigated. Color Doppler ultrasound was used to monitor the neck blood vessels to find whether there was CRT before chemotherapy and before taking out the port. The incidence of CRT, occurrence time, risk factors and treatment efficacy were observed. Results·There were 112 (58.9%) cases with CRT and 108 (56.8%) patients with asymptomatic thrombosis, and only 4 cases had symptomatic thrombosis, the incidence of which was 2.1%. Most thrombosis developed on the 21th day after catheterization, and the patients over the age of 60, with clinical stage Ⅲ - Ⅳ and chemotherapy regimens TEC (docetaxel combined pirubicin and cyclophosphamide) were the risk factors for thrombosis. All the patients with asymptomatic thrombosis accepted anticoagulant treatment with low molecular heparin, earthworms enzyme or aspirin, respectively, but there was no significant difference in efficacy in the three groups (P=0.743). Conclusion·Port catheter related symptomatic thrombosis incidence is low but the incidence of symptomatic thrombosis is high in the breast cancer patients after chemotherapy. Age, tumor stage and TEC chemotherapy regimens are the risk factors for catheter-related thrombosis.

ABSTRACT
This study aimed to investigate the causes and managements of the fractures and migrations of the implantable venous access port catheter (IVAPC). The fracture or migration of IVAPC occurred in 4 patients who were treated between May 2012 and January 2014 in Union Hospital, Wuhan, China. The port catheter leakage was found in 2 cases during drug infusion. Catheters that dislodged to the superior vena cava and right atrium were confirmed by port angiogram. The two dislodged catheters were successfully retrieved by interventional procedures. Catheter fracture occurred in two cases during port removal. One catheter was eventually removed from the subclavian vein through right clavicle osteotomy and subclavian venotomy, and the other removed by external jugular venotomy. Flushing the port in high pressure and injury of the totally implantable venous access port (TIVP) during implantation are usually responsible for catheter displacement. Interventional retrieval procedure can be used if the catheter dislodges to the vena cava and right atrium. Catheter fracture may occur during removal if clipping syndrome occurs or the catheter is sutured very tight during implantation.

ABSTRACT
Aim of The Study: A totally implantable venous access port (TIVAP) has become an essential prerequisite for many chemotherapy protocols. It is serving its purpose very well, but its use is not without complications. We are presenting our experience with these devices (TIVAPs). Subjects and Methods: We retrospectively reviewed the totally implantable venous access ports in 81 patients at our hospital between January 2009 and March 2011 for long-term problems which include postoperative and follow-up problems, excluding the immediate complications which occur at the time of insertion. Results: Catheter malfunction was the most common complication (9.87%, 0.40/1000 device-days of use/observation). Catheter-related bloodstream infections were present in 5 (6.17%) patients (0.25/1000 device-days of use/observation). The mean life of the catheter was 246 days. Only 11.1% ports required removal during the treatment period. Overall, patients either completed treatment (82.8%) or died (6.1%) while receiving treatment. Conclusion: TIVAPs provide safe and reliable vascular access for patients on chemotherapy but require utmost care by a dedicated team of trained medical professionals and paramedics experienced with the use of such ports, in order to minimize the complications and their continued use while administering treatment.
