Complications after percutaneous placement of totally implantable venous access ports in the forearm

A novel incision technique of a totally implanted venous access port in the upper arm for patients with breast cancer

BACKGROUND

A totally implanted venous access port (TIVAP) in the upper arm is a safe and cost-effective vascular access device and is widely used in breast cancer patients. Traditional tunnelling technique increases the operation time and has an unsatisfied cosmetic effect, so we explored the feasibility, cosmetic effect and complications of an upper arm port with a novel incision in this retrospective study.

METHODS

We reviewed 489 cases of totally implantable venous access port implantation in the upper arm with two types of incisions in our centre from 1 January 2018 to 30 January 2022. The patients were divided into two different incision groups including the puncture site incision group (n = 282) and the conventional tunnelling group (n = 207). The comparison of the results was collected between the two groups, and contributing factors were analyzed for major complications.

RESULTS

A total of 489 patients were successfully implanted with arm ports using the puncture site incision technique (n = 282, 57.7%) and conventional tunnelling technique (n = 207, 42.3%). The average operation time of the two types of incisions was 36.5 ± 15 min in the puncture site incision group and 55 ± 18.1 min in the tunnel needle group (P < 0.05). In terms of complications, 33 catheter-related complications occurred (6.4%), including 9 cases of infection, 15 cases of catheter-related thrombosis and 7 cases of skin exposure. Fourteen patients in the puncture site incision group developed complications compared with 17 in the traditional incision group. There were no significant differences between the two groups in terms of overall complication events (5.0% and 8.2%, P = 0.145) while the same result was found in each complication event. Weight, total cholesterol and diabetes were found to be associated with device-related infections in the univariate Cox proportional hazard regression models. Diabetes was found to be associated with device-related infections in multivariate analysis while hypertension was associated with thrombosis.

CONCLUSIONS

The puncture site incision method is a novel technique with a better cosmetic appearance and less operation time than the traditional tunnelling technique, providing a comparable overall rate of complications. It offers a preferable choice for clinicians when dealing with different situations of patients. It is worthy of being used and promoted for patients requiring the totally implanted venous access port in the upper arm.

Percutaneous implantation of peripherally inserted totally implantable venous access systems in the forearm in adolescent patients

BACKGROUND

Children with different underlying malignant diseases require long-term central venous access. As for port systems in a pectoral position, peripherally implanted port systems in the forearm revealed high levels of technical and clinical success in adult cohorts.

OBJECTIVE

To investigate the technical and clinical outcomes of percutaneous central venous port implantation in the forearm in adolescents.

MATERIALS AND METHODS

Between April 2010 and August 2020, 32 children ages 9 to 17 years with underlying malignancy received 35 totally implantable venous access ports (TIVAPs) in the forearm. All venous port systems were peripherally inserted under ultrasound guidance. Correct catheter placement was controlled by fluoroscopy. As primary endpoints, the technical success, rate of complications and catheter maintenance were analyzed. Secondary endpoints were the side of implantation, vein of catheter access, laboratory results on the day of the procedure, procedural radiation exposure, amount of contrast agent and reasons for port device removal.

RESULTS

Percutaneous TIVAP placement under sonographic guidance was technically successful in 34 of 35 procedures (97.1%). Procedure-related complications did not occur. During the follow-up, 13,684 catheter days were analyzed, revealing 11 complications (0.8 per 1,000 catheter-duration days), Of these 11 complications, 7 were major and 10 occurred late. In seven cases, the port device had to be removed; removal-related complications did not occur.

CONCLUSION

Peripheral TIVAP placement in the forearms of children is a feasible, effective and safe technique with good midterm outcome. As results are comparable with standard access routes, this technique may be offered as an alternative when intermittent venous access is required.

Outcome analysis in 270 radiologically guided implantations of totally implantable venous access ports via basilic vein

BACKGROUND

Totally implantable venous access ports (TIVAPs) are widely applied in patients who require chemotherapy, parenteral nutrition, or frequent intravenous drug infusion. Although various venous access routes are possible for TIVAP insertion, the best method remains a topic of controversy. We present a single-center retrospective study of radiologically guided placement of TIVAPs through the basilic vein, with analysis of technical feasibility, patient safety, and device-related complications.

METHODS

We retrospectively reviewed 270 patients who received TIVAP implantation through the basilic vein from November 2013 to July 2016, under imaging guidance by an interventional radiology team at our institution. Fluoroscopic images, chest radiographs, computed tomography scans, and medical records were reviewed after port implantation. Catheter maintenance days were calculated and catheter-related complications were recorded.

RESULTS

The procedural success rate was 99.3%. In total, 270 TIVAPs were implanted in 270 patients, of which 150 remained functional at the end of the study period. The total catheter maintenance days was 77 543 days, and the mean catheter indwelling duration was 287 ± 207 days. In 20 (7.4%) patients, TIVAP-related complications occurred during the follow-up period, resulting in a postprocedural complication rate of 0.26 incidences per 1000 catheter days. No significant relationship was observed between complications and gender (p = 0.188), age (p = 0.528), body mass index (p = 0.547), the type of primary malignancy (p = 0.914), or between the left and right basilic veins (p = 0.319).

CONCLUSION

Real-time ultrasound and fluoroscopic guidance provides a safe method for TIVAP implantation through the basilic vein, with a high technical success rate and few device-related complications.

Upper-Extremity Deep Vein Thrombosis in Patients With Breast Cancer With Chest Versus Arm Central Venous Port Catheters

Most of the patients undergoing treatment for cancer require placement of a totally implantable venous access device to facilitate safe delivery of chemotherapy. However, implantable ports also increase the risk of deep vein thrombosis and related complications in this high-risk population. The objective of this study was to assess the incidence of upper-extremity deep vein thrombosis (UEDVT) in patients with breast cancer to determine whether the risk of UEDVT was higher with chest versus arm ports, as well as to determine the importance of previously reported risk factors predisposing to UEDVT in the setting of active cancer. We retrospectively reviewed the medical records of 297 women with breast cancer who had ports placed in our institution between the dates of December 1, 2010, and December 31, 2016. The primary outcome was the development of radiologically confirmed UEDVT ipsilateral to the implanted port. Overall, 17 of 297 study subjects (5.7%) were found to have UEDVT. There was 1 documented case of associated pulmonary embolism. Fourteen (9.5%) of 147 subjects with arm ports experienced UEDVT compared with only 3 (2.0%) of 150 subjects with chest ports (P = .0056). Thus, implantation of arm ports as opposed to chest ports may be associated with a higher rate of UEDVT in patients with breast cancer.
