The feasibility and safety of PICCs accessed via the superficial femoral vein in patients with superior vena cava syndrome

Comparison of outcomes from tunnelled femorally inserted central catheters and peripherally inserted central catheters: a propensity score-matched cohort study

OBJECTIVES

To compare catheter-related outcomes of individuals who received a tunnelled femorally inserted central catheter (tFICC) with those who received a peripherally inserted central catheter (PICC) in the upper extremities.

DESIGN

A propensity-score matched cohort study.

SETTING

A 980-bed tertiary referral hospital in South West Sydney, Australia.

PARTICIPANTS

In-patients referred to the hospital central venous access service for the insertion of a central venous access device.

PRIMARY AND SECONDARY OUTCOME MEASURES

The primary outcome of interest was the incidence of all-cause catheter failure. Secondary outcomes included the rates of catheters removed because of suspected or confirmed catheter-associated infection, catheter dwell and confirmed upper or lower extremity deep vein thrombosis (DVT).

RESULTS

The overall rate of all-cause catheter failure in the matched tFICC and PICC cohort was 2.4/1000 catheter days (95% CI 1.1 to 4.4) and 3.0/1000 catheter days (95% CI 2.3 to 3.9), respectively, and when compared, no difference was observed (difference -0.63/1000 catheter days, 95% CI -2.32 to 1.06). We found no differences in catheter dwell (mean difference of 14.2 days, 95% CI -6.6 to 35.0, p=0.910); or in the cumulative probability of failure between the two groups within the first month of dwell (p=0.358). No significant differences were observed in the rate of catheters requiring removal for confirmed central line-associated bloodstream infection (difference 0.13/1000 catheter day, 95% CI -0.36 to 0.63, p=0.896). Similarly, no significant differences were found between the groups for confirmed catheter-related DVT (difference -0.11 per 1000 catheter days, 95% CI -0.26 to 0.04, p=1.00).

CONCLUSION

There were no differences in catheter-related outcomes between the matched cohort of tFICC and PICC patients, suggesting that tFICCs are a possible alternative for vascular access when the veins of the upper extremities or thoracic region are not viable for catheterisation.

Totally implanted central venous access devices inserted by the femoral route: A narrative review and the proposal of a novel approach, the FICC-port

BACKGROUND

Femoral ports are used in patients with indication to a totally implanted venous access device but with contraindication to chest-ports and brachial ports because of obstruction of the superior vena cava. In the last three decades, femoral ports have been implanted almost exclusively by cannulation of the common femoral vein at the groin, while the position of the tip has been assessed by X-ray.

METHODS

We report our experience with a new approach to femoral ports, which includes recent methods and techniques developed in the last few years. These novel femoral ports, which we call "FICC-ports," are characterized by (a) long femoral 5 Fr polyurethane catheter inserted by ultrasound-guided puncture of the superficial femoral vein at mid-thigh; (b) intraprocedural location of the tip in the sub-diaphragmatic inferior vena cava, using ultrasound visualization by the transhepatic and/or the subcostal view; (c) low-profile or very low-profile reservoir implanted above the quadriceps muscle, at mid-thigh.

RESULTS

In the last 3 years, we have implanted 47 FICC-ports in young adults with mediastinal lymphoma compressing the superior vena cava. We had no immediate/early complication, and only three late complications (one kinking of the catheter in the subcutaneous tissue; one tip migration with secondary venous thrombosis; one persistent withdrawal occlusion due to fibroblastic sleeve).

CONCLUSION

If there is indication to a femoral port, the implantation of a "FICC-port"-as described above-is to be strongly considered in terms of safety, effectiveness, and cost-effectiveness: no immediate-early complications, minimal late complications, no X-ray exposure, low invasiveness, low cost.

Femoral to abdomen tunneling at the bedside for medium/long term venous access

BACKGROUND

Femoral to abdomen tunneling of small-bore central venous catheters is a bedside technique for patients with contraindications to a thoracic approach, or as an alternative to a lower extremity catheter exit site.

METHOD

A femoral to abdomen tunneling technique was implemented for patients receiving medium and long-term intravenous treatments with contraindications to the thoracic venous approach or as an alternative to a lower extremity catheter exit site. All venous access devices were inserted with ultrasound guidance under local anesthesia, and catheter tip placement assessed by post procedural radiography.

RESULTS

In this case series, from January 2020 to January 2023, a total of eight FTA-tunneled venous access devices were inserted. There were seven ambulatory patients and one bedbound patient. The median length of the subcutaneous tunnel was 20 cm, ranging from 15 to 27 cm. The median length of the intravenous catheter to the terminal tip was 31 cm, ranging from 23 to 40 cm. Tip location was confirmed by post-procedural abdominal radiograph. The catheter tip locations were interpreted to be at the level of T8-T9 (2), T12 (1), L4 (2), L2 (2), L1(1).No insertion or post insertion related complication was reported. Six patients completed the scheduled intravenous treatment. One patient was unable to be tracked due to transfer to an outside facility. One catheter initially demonstrated to be coiled over the left common iliac vessel was repositioned using a high flow flush technique. There was one reported catheter dislodgment by the nurse providing care and maintenance. The overall implant days were 961, with a median dwell time of 125 days ranging from 20 to 399 days.

CONCLUSION

Femoral to abdomen tunneling provides an alternative exit site useful in select patients with complex intravenous access. The data of this small retrospective review suggests this a safe and minimally invasive bedside procedure.

End-stage renal disease in a critical patient with superior vena cava syndrome with central vein catheters inserted via the superficial femoral vein: A case study

Superior vena cava syndrome (SVCS) is caused by obstruction to the blood flow through this vein. Indwelling central venous devices, such as cardiac pacemakers and haemodialysis catheters have emerged as the most common benign aetiology of SVCS. SVCS is particularly severe in patients with end-stage renal disease who require continuous renal replacement therapy plus infusion therapy. The presence of SVCS results in a reduction of available venous access for affected patients. Therefore, venous access plays a crucial role in the management of these patients. The importance of dealing with vascular access (VA) in critical patients with these conditions cannot be overstated. This case describes an 81-year-old man with respiratory failure who had end-stage renal disease complicated with SVCS. Using ultrasound-guided puncture, we inserted a peripherally inserted central catheter (PICC) into the superficial femoral vein to meet his infusion requirements in intensive care. After successful placement, the catheter tip position was adjusted using imaging to position the tip relative to the haemodialysis catheter. Whenever patients with severe renal dysfunction are treated, central veins should be preserved. Safe PICC access is possible via the superficial femoral vein to protect the last central VA for rational use. This meets urgent needs for infusion and deserves promotion.

Femoral venous access: State of the art and future perspectives

In the past 5 years, non-dialysis femoral venous access has changed in terms of indications, techniques of insertion, and expected incidence of complications. To the traditional non-emergency indication for femoral catheters-obstruction of the superior vena cava-many other indications have been added, both in intensive and non-intensive care. The insertion technique has evolved, thanks to ultrasound guided venipuncture, tunneling, and ultrasound based intraprocedural tip location. Insertion of femorally inserted central catheters may be today regarded as a procedure with an extremely low intraprocedural and post-procedural risk. The risk of infection is reduced by the possibility of the exit site at mid-thigh, by the use of cyanoacrylate glue for sealing the exit site, and by appropriate intraprocedural strategies of infection prevention. The risk of catheter-related thrombosis is low, due to several concomitant strategies: a proper match between vein diameter and catheter caliber; an accurate intraprocedural assessment of tip location by ultrasound and/or intracavitary ECG; the consistent use of ultrasound guided venipuncture and micro-introducer kits; an adequate stabilization of the catheter at the exit site. The risk of mechanical complications and the risk of lumen occlusion are minimized when using polyurethane, power injectable catheters. All these novelties have brought a revolution in the field of femoral venous access, so that this route may be considered as safe and effective as other approaches to central venous catheterization.

Midline peripheral catheters inserted in the superficial femoral vein at mid-thigh: Wise choice in COVID-19 acute hypoxemic respiratory failure patients with helmet continuous positive airway pressure

BACKGROUND

During coronavirus disease 2019 (COVID-19) pandemic, Helmet Continuous Positive Airway Pressure (h-CPAP) has been widely used to treat Acute Hypoxemic Respiratory Failure (AHRF). In COVID-19 patients undergoing h-CPAP a simple short peripheral catheter could be insufficient. According to the European Recommendations for Proper Indication and Use of Peripheral venous access consensus, a stable peripheral Vascular Access Device is indicated for intravenous treatment compatible with the peripheral route scheduled for more than 1 week.

OBJECTIVE

The aim of this prospective study was to evaluate the performance and the potential complications of superficial femoral midline catheters (SFMC) inserted in the Superficial Femoral Vein by direct Seldinger technique with peripheral tip (Arrow®, Teleflex; 20 cm length four FR single lumen and seven FR dual lumen) in AHRF COVID-19 patient. Complications were divided in early (accidental puncture of superficial femoral artery (APSFA); accidental saphenous nerve puncture (ASNP); bleeding) and late (Catheter Related Thrombosis (CRT); Catheter-Related Bloodstream Infections (CRBSI); Accidental Removal (AR); persistent withdrawal occlusion (PWO)).

METHODS

From 1st October 2020 to 30th June 2021 we conducted a prospective observational study in COVID-19 sub-intensive wards at Luigi Sacco Hospital (Milan).

RESULTS

Hundred seventy five SFMC (mean dwell time 11.1 ± 9.8 days) were implanted in COVID-19 patients, 107 (61.1%) during h-CPAP treatment (10.5 ± 8.9 days), the remaining 68 (38.9%) in patients with severe disease. We recorded two minor immediate/early complications (APSFA without sequelae) and no major complications.The long-term follow-up registered four CRBSI (2.3%-2.5/1000 catheters days (CD)), five CRT (2.9%: 2.6/1000 CD), 22 AR (12.6%; 11.4/1000 CD), 38 PWO (36.5%), 34 of which occurred due to fibroblastic sleeve (32.7%).

CONCLUSIONS

SFMC proved to be safe, easy and time-saving. It could be implemented, after a careful benefits and risks evaluation, in particular settings such as h-CPAP, delirium, bleeding risk factors and palliative care patients.

The SIF protocol: A seven-step strategy to minimize complications potentially related to the insertion of femorally inserted central catheters

The insertion of central venous catheters through the femoral veins is not uncommon and is potentially associated with the risk of immediate puncture-related complications and severe late complications as infection and thrombosis. As for other central venous access devices, the use of a standardized protocol of insertion and the correct application of evidence-based strategies are beneficial in reducing the risk of complications. We proposed a standardized protocol (S.I.F.: Safe Insertion of Femorally Inserted Central Catheters) consisting of seven strategies that should be part of vascular cannulation and should be adopted during the insertion of femoral venous catheters, aiming to minimize immediate, early and late insertion-related complications. These strategies include: preprocedural evaluation of the patient history and of the veins, appropriate aseptic technique, ultrasound guided puncture and cannulation of the vein, intra-procedural assessment of the tip position, adequate protection of the exit site, proper securement of the catheter, and appropriate coverage of the exit site.

ACR Appropriateness Criteria® Central Venous Access Device and Site Selection

The use of central venous access devices is ubiquitous in both inpatient and outpatient settings, whether for critical care, oncology, hemodialysis, parenteral nutrition, or diagnostic purposes. Radiology has a well-established role in the placement of these devices due to demonstrated benefits of radiologic placement in multiple clinical settings. A wide variety of devices are available for central venous access and optimal device selection is a common clinical challenge. Central venous access devices may be nontunneled, tunneled, or implantable. They may be centrally or peripherally inserted by way of veins in the neck, extremities, or elsewhere. Each device and access site presents specific risks that should be considered in each clinical scenario to minimize the risk of harm. The risk of infection and mechanical injury should be minimized in all patients. In hemodialysis patients, preservation of future access is an additional important consideration. The ACR Appropriateness Criteria are evidence-based guidelines for specific clinical conditions that are reviewed annually by a multidisciplinary expert panel. The guideline development and revision process support the systematic analysis of the medical literature from peer reviewed journals. Established methodology principles such as Grading of Recommendations Assessment, Development, and Evaluation or GRADE are adapted to evaluate the evidence. The RAND/UCLA Appropriateness Method User Manual provides the methodology to determine the appropriateness of imaging and treatment procedures for specific clinical scenarios. In those instances in which peer reviewed literature is lacking or equivocal, experts may be the primary evidentiary source available to formulate a recommendation.

Alternative vascular accesses in electrophysiological operating rooms: focus on the quality of life in the early postoperative period

Atrial fibrillation is the most common arrhythmia, the incidence of which increases in parallel with the progressive aging of the population. Atrial fibrillation worsens the prognosis of patients and significantly reduces the quality of life. Improvement of the technical and methodological aspects of catheter procedures leads to their widespread introduction into clinical practice both for the prevention of embolic events and for rhythm control. The need to provide access to the main vessels, more often to the femoral veins, the use of large bore introducers, as well as aggressive regimens of antithrombotic therapy in the postoperative period, bring to the fore local complications of catheter procedures and necessitates to maintain a horizontal position to achieve stable hemostasis. The use of ultrasound imaging can significantly reduce the number of vascular events. However, long-term immobilization often leads to back pain, urinary retention, and infectious complications, which is more pronounced in the older patient population. In order to reduce the immobilization time, many hemostasis systems have been developed, which have disadvantages and require additional costs for the treatment of patients. In this regard, the development and introduction into clinical practice of novel vascular access types to improve the quality of life in the early postoperative period seems relevant. For this purpose, a randomized study is conducted, which compares the efficacy and safety of the distal femoral access, which makes it possible to activate patients as soon as possible after surgery.

Intracavitary electrocardiography for femorally inserted central catheter tip location in adult patients

BACKGROUND

In this study, the intracavitary electrocardiogram (ECG) P-wave and QRS-wave changes during femorally inserted central catheter (FICC) placement in adults were observed with the aim of reducing malposition occurrence. The observed method provides venous access in patients who have limited upper limb venous catheterization potential and require medium-term and long-term infusions.

METHODS

A retrospective analysis of 34 adult patients who underwent FICC placement was conducted. After body surface measurements were taken, all patients were connected to an ECG during catheter placement, and the P-wave and QRS-wave changes were observed. Next, the catheter tip position was confirmed with an abdominal X-ray, and an analysis of the changes occurring during the procedure was conducted.

RESULTS

In the 34 patients included in the present study, the catheter tips were located below the diaphragm level in the inferior vena cava. Of the patients, 18 showed negative P waves, biphasic P waves, and positive high-amplitude P waves with increasing the insertion depth. In 16 patients, no P-wave characteristic changes were observed during catheterization, and an abdominal X-ray confirmed that the catheter tip was positioned below the level of the first lumbar vertebra.

CONCLUSION

Negative P waves, biphasic P waves, and positive high-amplitude P waves appeared during FICC placement in adults. Catheter withdrawal until the P wave reverted to normal indicated that a tip position close to the inferior vena cava above the diaphragm level was ideal.

Catheterization of PICC through a superficial femoral vein for patients with superior vena cava syndrome using ECG positioning and ultrasound-guided technologies

OBJECTIVE

We herein demonstrate the efficacy of PICC placement through a superficial femoral vein in patients with superior vena cava syndrome using ultrasound guidance and electrocardiographic localization. The treatment of PICC disconnection was also discussed.

METHODS

The study enrolled 51 patients with superior vena cava syndrome. Ultrasound-guided technology and ECG positioning technology are employed to help these patients in catheterization. The puncture time, the number of punctures, and catheter tip position were recorded. The patient was followed up for at least 2 years. The complications and treatment during follow-up were recorded.

RESULT

The average puncture time was 32.13 ± 3.91 min. A total of 49 patients were successfully punctured once, while 2 patients failed in the first puncture. The main reason for puncture failure is that the inability of a guide wire to pass through. After the nurse removed the needle and pressed the puncture point until no rebleeding occurred, the puncture above the original puncture point was successful. X-ray examination revealed that the catheter tip was located in the inferior vena cava, above the diaphragm, near the right atrium. The success rate of catheterization was 100%. The visual analog scale (VAS) score was (2.44 ± 0.73) at the time of puncture, which was tolerable during the operation, and the patient did not complain of obvious pain following the operation. One patient developed complications of broken tube half a year after the puncture. Interventional physicians utilized angiography to locate the broken catheter.

CONCLUSION

It is safe and feasible to place PICC through a superficial femoral vein under ultrasound combined with ECG positioning technology in patients with superior vena cava syndrome.

Ultrasound-guided cannulation of the superficial femoral vein for central venous access

BACKGROUND

In some clinical conditions, central venous access is preferably or necessarily achieved by threading the catheter into the inferior vena cava. This can be obtained not only by puncture of the common femoral vein at the groin, but also-as suggested by few recent studies-by puncture of the superficial femoral vein at mid-thigh.

METHODS

We have retrospectively reviewed our experience with central catheters inserted by ultrasound-guided puncture and cannulation of the superficial femoral vein, focusing mainly on indications, technique of venipuncture, and incidence of immediate/early complications.

RESULTS

From June 2020 to December 2020, we have inserted 98 non-tunneled central venous catheters (tip in inferior vena cava or right atrium) by ultrasound-guided puncture of the superficial femoral vein at mid-thigh or in the lower third of the thigh, all of them secured by subcutaneous anchorage. The success of the maneuver was 100% and immediate/early complications were negligible. Follow-up of hospitalized patients (72.5% of all cases) showed only one episode of catheter dislodgment, no episode of infection and no episode of catheter related thrombosis.

CONCLUSIONS

The ultrasound approach to the superficial femoral vein is an absolutely safe technique of central venous access. In our experience, it was not associated with any risk of severe insertion-related complications, even in patients with low platelet count or coagulation disorders. Also, the exit site of the catheter at mid-thigh may have advantages if compare to the exit site in the inguinal area.

Technical success and safety of peripherally inserted central catheters in the great saphenous and anterior accessory great saphenous veins

BACKGROUND

Peripherally inserted central catheters (PICC) are occasionally placed in the great saphenous vein (GSV) and anterior accessory great saphenous vein (AAGSV) in patients with inadequate upper extremity veins or contraindications to upper extremity placement. Outcomes on the placement of PICCs in these veins are limited.

OBJECTIVES

This study aimed to determine technical success and safety of GSV/AAGSV PICCs.

MATERIALS AND METHODS

This is a retrospective study that reviewed all GSV/AAGSV PICC placements between January 2011 and December 2019. A total of 29 PICC placements procedures were identified. The electronic medical record was queried for demographic, procedural, and complication data. Technical success was defined by whether the vein could be accessed and a PICC could be placed. Catheter-associated infections, dislodgement or migration, malfunction, and PICC-associated thrombosis were recorded.

RESULTS

Technical success of placement was 100%. Twenty-one (72%) catheters were placed in the GSV in the mid to upper thigh and eight (28%) were placed in the AAGSV. The median PICC dwell time was 13 days with a range of 3-155 days. PICC-associated complications occurred after 11 (37.9%) placements. Line associated infection was the most common complication (17.2%).

CONCLUSION

Due to a high complication rate, GSV/AAGSV PICC placement should be considered only when upper extremity or cervical PICC placement is not feasible or contraindicated.

The application of intracavitary electrocardiogram for tip location of femoral vein catheters in chemotherapy patients with superior vena cava obstruction

BACKGROUND

Most studies focused on the application of intracavitary electrocardiogram (IC-ECG) location in superior vena cava access catheterization, this study aimed to explore the effect of IC-ECG for tip location of femoral vein catheters in chemotherapy patients with superior vena cava obstruction (SVCO).

METHODS

A total of 158 patients placed catheters through superficial femoral vein from July 2016 to May 2019 were enrolled in the randomized controlled study. The patients were divided into two groups by envelope lottery method: X-ray location was used in the control group (n = 79); IC-ECG location was used in the observation group (n = 79). The catheters should be located at or near the inferior vena cava (IVC)-right atrium (RA) junction (above the level of diaphragm within the IVC). The general information of patients, clinical catheterization effects and catheter-related complications were compared between the groups.

RESULTS

No significant differences in general information, catheter obstruction, catheter-related thrombosis, catheter exit-site bleeding and infection were found between the groups. The rate of successful insertion at the first attempt and patient satisfaction in the observation group were significantly higher than that in the control group (p < 0.05). The time and cost of location and the incidence of catheter-related complications in the control group were 32.57 min and 140.51 Yuan and 21.5%, which were significantly higher than 6.94 min and 13.59 Yuan and 7.6% in the observation group (p < 0.05).

CONCLUSION

IC-ECG accurately located the tip of femoral vein catheters, reduced the incidence of catheter-related complications and the time and cost of location, improved patient satisfaction.

Cannulation of the superficial femoral vein at mid-thigh when catheterization of the superior vena cava system is contraindicated

PURPOSE

Patients needing medium- to long-term infusion therapy with limited catheterization via the superior vena cava system is a challenging condition. The conventional catheterization via the femoral vein in the groin has a high complication rate, discomfort, and short indwelling time. Since changing the insertion site can avoid the disadvantage of conventional catheterization via the femoral vein in the groin, the present study aimed to investigate the effects of femoral inserted central catheters insertion via the superficial femoral vein at the mid-thigh to resolve the issue of limited superior vena cava system catheterization.

METHODS

Based on the symptoms and signs, enhanced computed tomography findings, and insertion history, in 121 patients, limited catheterization via the superior vena cava system was identified. Subsequently, the femoral inserted central catheters were inserted via the superficial femoral vein at the mid-thigh under the guidance of ultrasound, and the tip of femoral inserted central catheters was in the inferior vena cava.

RESULTS

A total of 121 patients underwent femoral inserted central catheters insertion via a superficial femoral vein at the mid-thigh from August 2017 to December 2018. The success rate of insertion was 100%, and the indwelling time was 3-472 days. The complications of femoral inserted central catheters in the thigh were similar to that of peripherally inserted central catheters in the arm. The incidence of primary malposition was 1.65%, the incidence of catheter-related thrombosis was 0.83%, and the central line associated bloodstream infection rate was 0.83%. Subsequently, 116 lines (95.87%) were removed at the end of the treatment, one line (0.83%) was accidentally removed by the patient, and four lines (3.31%) were unplanned removed due to complications.

CONCLUSION

The technique of femoral inserted central catheters insertion via the superficial femoral vein at the mid-thigh has a high success rate, low complication rate, and less impact on activities, and is easy to maintain. This phenomenon resolves the patient's needs of medium- to long-term infusion therapy with limited catheterization of superior vena cava system.

Review and Case Studies of Midthigh Femoral Central Venous Catheter Placement

Background: Bedside vascular access options have been limited to the short peripheral intravenous, midline catheter, peripherally inserted central catheter, and central venous catheter (CVC) insertion sites such as the jugular, subclavian, and femoral vein. Many patients with limited options for upper extremity, subclavicular, supraclavicular, and cervical limitations have traditionally received a femoral CVC in the inguinal region. This insertion site is considered a high risk for infection because of its location in the inguinal region and associated difficulties with maintaining the dressing integrity. An alternative location was selected for the insertion of a femoral vein central venous catheter in the midthigh to reduce the risk of infection.

Methods: After a multiple-year implementation process, midthigh femoral (MTF) insertions were performed on a select group of patients. The case studies that are included in this report outline the indications, procedures, and other pertinent aspects of the MTF placement. Patients at this institution with contraindications to upper extremity and thoracic catheter insertion received a MTF vein CVC in place of a traditional common femoral vein catheter insertion in the inguinal area. All procedural consents include permission for photography of procedure sites.

Results: All but a single patient completed their therapy without complication; 1 intentional dislodgement by a patient was recorded. There were no MTF catheter-related bloodstream infections and 2 confirmed central line associated bloodstream infections (n = 2 of 100) with the second noted as probable contaminated specimen. Outcomes reflected no procedural complications (eg, expanding hematoma or femoral nerve injury or any other femoral artery or vein injuries) and 1 nonocclusive deep vein thrombosis (n = 1 of 100).

Conclusions: The MTF CVC provides an alternative to traditional common femoral vein catheter placement for nonemergent patients with upper extremity and thoracic contraindications to central line placement.
