Cephalic Vein Cut-Down Method for Totally Implantable Venous Access Ports: A Single-Institution Experience

BACKGROUND

The widespread use of chemotherapies has increased the need for totally implantable venous access ports (TIVAPs). Previously, the subclavian puncture approach with the landmark technique was the most used implantation method; however, it has been related to early complications such as pneumothorax, hemothorax, and arterial puncture. Therefore, a safer implantation method is required. This study aimed to assess the safety and efficacy of the cephalic vein cut-down method used in our institution.

METHODS

Patients who underwent TIVAPs implantation using the cephalic vein cut-down method as the first choice between January 1, 2018, and December 31, 2020, were included in this study. We retrospectively evaluated the technical success rates, operation times, and early complications.

RESULTS

This study included 221 adult patients (men, 129; women, 92), with a mean age of 68 ± 11 years. The mean body mass index (BMI) was 21 ± 4 kg/m2. A total of 213 patients (96.4%) had malignant tumors that required chemotherapy. The mean postoperative follow-up period was 659 ± 442 days (range, 5-1,698 days). A total of 127 patients (57.5%) died during the follow-up period. The technical success rate was 86.4% (191/221). There were 30 failures, 24 of which were converted to the subclavian vein puncture approach. The mean operation time was 53 ± 21 min. Early complications were observed in 4 (1.8%) patients, corresponding to an incidence of 0.028 complications/1,000 catheter days. One patient had an unintended arterial puncture; however, it was not a result of the cephalic vein cut-down method but a secondary result of the subclavian vein puncture. No complications of pneumothorax, hemothorax, or arterial puncture were observed with the cephalic vein cut-down method.

CONCLUSIONS

This study showed that the cephalic vein cut-down method for TIVAPs had an acceptable success rate and fewer early complications than the conventional puncture techniques.

Cephalic Vein Cut Down for Total Implantable Venous Access Ports: A Retrospective Review of a Single Institution Series

Objective

The aim of this work was to describe the early and late success rates of cephalic vein cut down (CVC) in the implantation of totally implantable venous access ports (TIVAP) for chemotherapy treatment in oncological patients.

Methods

This was a retrospective study of 1 047 TIVAP performed in a private institution between 2008 and 2021. The CVC with pre-operative ultrasound (PUS) was the initial approach. All cephalic veins (CVs) were mapped pre-operatively with Doppler ultrasound, measuring their diameter and course in oncological patients who required a TIVAP. With a CV diameter ≥ 3.2 mm TIVAP was carried out by CVC; with CV diameter < 3.2 mm, subclavian vein puncture (SVP) was performed.

Results

1 047 TIVAPs were implanted in 998 patients. The mean age was 61.5 ± 11.5 years, 624 were women (65.5%). Male patients were significantly older and with a higher incidence of colonic, digestive system, and laryngeal cancer. Initially, TIVAP was indicated in 858 cases (82%) by CVC and 189 (18%) by SVP. The success rate was 98.5% for CVC and 98.4% for SVP. There were no complications for CVC (0%) but five early complications (2.5%) in the SVP group. The rates of late complications were 4.4% in the CVC group and 5.0% in the SVP group, foreign body infection being the most frequent (57.5% of the cases) (p = .85).

Conclusion

The CVC or SVP using PUS for TIVAP deployment, performed through a single incision, is a safe and effective technique. This open but minimally invasive technique should be considered in oncological patients.

Outcome Comparison of Totally Implantable Venous Access Device Insertions Between Surgeons and Radiologists in Australia

Background

The need for chemotherapy treatment is increasing with the growing incidence of cancer worldwide. The insertion of totally implantable venous access devices (TIVADs) is commonly performed by surgeons and radiologists, but the procedures are not without complications. The primary outcome of this review outlines TIVAD insertion success and complication rates between general surgeons and radiologists. The secondary goal of this study is to help identify areas for improvement and consideration when performing TIVAD insertion.

Methodology

This was a descriptive, three-year, retrospective multicentre study of oncological patients who underwent TIVAD insertion by either general surgeons or radiologists at two peripheral Brisbane hospitals.

Results

Surgeons performed 61 percutaneous subclavian vein cannulations, 29 ultrasound-guided internal jugular veins, and seven open cephalic veins cut-down TIVAD insertions (n=97). Overall surgical success was 81.4%, with the internal jugular (89.7%) having the highest success rate followed by the open cut-down (85.7) and subclavian approaches (77.0%). The overall surgical complication rate was 16.4%, with five pneumothorax, five port malfunctions, three haemorrhages, two infections, one thrombus, and one mediastinal injury. Each pneumothorax was associated with subclavian cannulation attempts. Two haemorrhages were associated with both open cephalic and subclavian attempts. Radiologists performed 248 ultrasound-guided internal jugular vein TIVAD insertions (n=248) with 247 successful first attempts (99.5%). Within the radiology group, there was an overall complication rate of 15.3% with 22 infections, 14 port malfunctions, one haemorrhage, and 1 mediastinal injury.

Conclusion

Ultrasound-guided internal jugular vein TIVAD insertion had the highest first attempt success rate in both the surgical and radiology groups.

Detachment and embolization of totally implantable central venous access devices: diagnosis and management

BACKGROUND

Detachment and embolization (DE) is a rare complication of totally implantable central venous access devices (TIVADs). This study aimed to analyze clinical findings, etiology, and treatment options in DE of TIVADs.

METHODS

Patients who experienced DE between 2010-2019 were included. Indications, implantation techniques, time to diagnosis, patient complaints, diagnostic methods, rupture site, location of embolization, treatment methods, and chest X-rays prior to detachment were analyzed retrospectively.

RESULTS

DE of TIVAD was detected in 12(1.2%) patients. Eleven patients had breast cancer and one had colon cancer. Mean age at implantation was 45.3 ± 9.6(31-61.3) years. Seven (58%) patients were asymptomatic, four (33.3%) had TIVAD malfunction, and one (8.3%) had pain and swelling at port site after injection. Mean time from implantation to diagnosis was 1149.92(16-2795) days. The etiologies comprised Pinch-off Syndrome (POS) in eight (66%) patients, detachment directly adjacent to the lock mechanism in three (25%) patients, and probable iatrogenic injury during explantation in one (9%) patient. The most common site of embolism was the superior vena cava (25%). While the embolized fragment was removed percutaneously in 11 patients, medical follow-up was treatment choice for one patient.

CONCLUSIONS

DE is a rare complication with an incidence rate of 1.2% in this study. Since most patients were asymptomatic, chest radiography plays an important role in diagnosis. The most common cause was POS, and it can be prevented by inserting the catheter from lateral third of the clavicle during subclavian vein catheterization. The first-choice treatment was percutaneous femoral retrieval. However, if not technically possible, alternative treatment options are thoracotomy or follow-up with anticoagulant therapy.
