Objectives: To compare internal jugular vein approach and upper arm approach through basilic or cephalic veins in insertion of total implantable central venous port regarding early post-operative complications, patency rate, compliance and patient quality of life.
Methods: We identified 50 patients who underwent totally implantable venous access ports (TIVAP) implantation in the arm (25 patients) or chest (25 patients) between November 2015 and November 2017. Implantation via an upper arm (cephalic or basilic) occurred through venous cut down, the internal jugular vein was performed using percutaneous technique.1 All approaches were under fluoroscopic guidance. Early, postoperative complications were evaluated. During follow up, self-compliance and quality of life were assessed as well.
Results: Technical success was 100%. Procedure-related arterial injury occurred in 3 patients in central approach only, post-operative hematoma or stitch inflammation and seroma were observed. Late complications included catheter infection, occlusion, pinch off syndrome and skin dehiscence. Thrompophlepities of the vein and extravasation in both techniques were documented and quality of life was assessed during follow up.
Conclusions: Totally implantable venous access ports (TIVAP) can be implanted with high technical success rates, and are associated with low rates of complications. Upper arm implantation may benefit clinicians and patients with respect to safety and comfort.
Key words: Central venous catheters, peripheral portacath, chemotherapy.
Introduction
The number of cancer patients has been increasing worldwide due to progressive society ageing. Rapid developments in outpatient cancer chemotherapy have exponentially increased the need for implantable central venous (CV) ports.2 Totally implantable venous access ports (TIVAP) are widely used and allow for administration of chemotherapy and artificial nutrition as well as blood sampling. These devices have been evaluated extensively in various locations, e.g. the chest, upper arm and forearm, generally showing excellent results as to technical success and low rates of complications3 with the reservoir positioned in the arm. The potential benefits that justify a more detailed study of this technique include reducing the risk of intraoperative complications such as arterial injury, pneumothorax or hemothorax, noninterference in breast imaging, easier access to puncture, better cosmetic results and better quality of life.4
Patients and methods
In this retrospective study, we identified 50 patients
who underwent percutaneous TIVAP implantation between Novembers 2015 and November 2017 in Gamal Abd-Elnaser hospital, Alexandria and Ain Shams University Hospitals and were suffering from different neoplastic diseases requiring chemotherapy. Patients’ demographic and baseline characteristics are highlighted in Tables 1-3. Indications for TIVAP insertion was to have chemotherapy. All patients were examined and treated as part of routine care, and provided informed consent. Institutional review board approval was not required. 25 patients were men and 25 were women.
24 patients presented with cancer colon (48%) (11 central and 14 peripheral), 4 patients with cancer stomach (8%) (2 central and 2 peripheral), 2 with bone cancer (4%) (one central and one peripheral), 4 with cancer esophagus (8%) (3 central and one peripheral),
10 with cancer breast (20%) (5 entral and 5 peripheral) and 6 with other malignances (12%). 25 patients had central approach while the other 25 patients had peripheral approach, (18 of them were basilic and the other 7 patients were cephalic).

Description of upper arm central venous port implantation
The access route of choice was the right arm as shown in (Figure 1), the preparation for surgery included shaving the catheter implantation site when necessary, and disinfection of the entire limb with Betadine.
To reduce the difficulty in obtaining the vein by cut
down technique, intraoperative duplex was used to determine site of cut down on basilic or cephalic veins.
In the operative room, the patient was placed in the supine position, allowing the upper limb to abduct, upper arm to rotate outward in basilic and inward in cephalic approach, forearm to supinate
in basilic or pronate in cephalic approach, and medial side of the arm to be upward for better demonstration of the basilic vein. The elbow was bent; the forearm was pronated in basilic approach.
Central venous catheter placement and port implantation
The point for a skin incision was 3-4 finger breadth from medial or lateral epicondyle of the arm. Local anesthetic was applied to areas about 2 cm right and left from the point for a skin incision and to areas 2 cm peripheral from these to establish a subcutaneous pocket. Subsequently, a scalpel was used to make a skin incision from 2 cm to the right to 2 cm to the left of the incision point. This incision was used later as the entrance for making a subcutaneous pocket with a forceps, the connective tissues between the skin and the basilic vein were removed and the basilic vein was identified and peripheral cannula 22 g (rose) was used to puncture the vein.
A guide wire (0.14 mm) was inserted through the lumen of the peripheral cannula placed in the vein and carried forward until SVC was reached under X-ray fluoroscopic guidance. If there was abnormal resistance during wire passage, appropriate use of a contrast dye was helpful to confirm a run-through of the vessel and presence of stenosis or occlusion. After introducing the guide wire, the peripheral catheter was withdrawn. The dilator and the sheath were introduced for 5 cm in the vein then the dilator was removed and the catheter was introduced over the wire through the sheath (the catheter was introduced over the wire directly without the sheath or the dilator).
The catheter was appropriately positioned in the SVC. The optimal CV catheter tip location was about 2 cm passed centrally from the carina, as recognized by fluoroscopy. The sheath was peeled off.
A subcutaneous pocket for a port was made by blunt dissection using forceps (Figure 2). The port and catheter was then connected according to the manufacturer’s manual. Fixing the port to connective tissue through the suture hole was optional with our upper arm method. Finally, the skin was sutured appropriately while avoiding pricking the catheter.
Fig 1: Description of site of peripheral basilic insertion.
For pectoral placement
Following local anesthesia, the internal jugular vein was accessed using the percutaneous technique with micro puncture needle. Subsequently, the wire was introduced and confirmed that it was in the correct position under fluoroscopic guidance.
Following preparation of the port pocket in the chest, a tunneling device was used to cross the distance between the pocket and the initial puncture site subcutaneously.
The peel-away sheath was placed in the internal jugular vein. The catheter tip was inserted via the sheath under fluoroscopic guidance and placed centrally with the tip aiming at the vertebral body below the carina.
After tunneling the distance between the initial vascular access site and the pocket, the catheter was cut to adequate length and connected to the port chamber. Correct and central placement of the catheter tip as well as the loop-free run of the catheter in the tunneled area was documented by fluoroscopy.
The port was fixed to the pectoral muscle fascia by proline suture 4\0. The pocket was closed with one layers of suture, as the vascular access site was closed with one cutaneous stitch only.
At the end of all procedures, all TIVAP were accessed with a non-coring puncture needle, before needle removal, the catheter was flushed with of heparinized sodium chloride (5000 u). Following pectoral implantation, pneumothorax was ruled out by chest X-ray after expiration.
Intraoperative data, such as operating time, type of anesthesia, access route changes and intraoperative complications were recorded for further evaluation.
Patients were instructed to keep applying sterile occlusive dressings for 3 days after the procedure. In case of need for immediate use of the device, the puncture was performed in surgical room.

Follow up
Patients included in the sample were clinically evaluated at 10 and 30, days, 3 and 6 months after the procedure and at the end of chemotherapy or at any other time of the study in case of any catheter-related intercurrent events.
Additional tests such as X-ray or Doppler ultrasound were requested only if the patient complained of symptoms related to the catheter (e.g., dysfunction, edema or changes related to the surgical wound).
The primary outcomes assessed were the early
postoperative complications, defined as events occurring within 30 days after implantation and late complications which occur after that.
A satisfaction questionnaire was applied in the second evaluation, after 30 days of implantation. From the patients’ perspective, this questionnaire analyzed data involving recognition of the need for the device, aspects of comfort; anxieties generated by the use of the device; interference in daily activities; aesthetics and overall satisfaction based on the recommendation grade indicated by the patient.
The patients were asked whether they agreed or disagreed with statements relating to the different aspects of satisfaction analyzed. The results of the questionnaire were compared.
Results
In preprocedural periods 18 patient, (36%) in the group of central approach required O2 mask in Trendlenberg positioning while no one in peripheral approach required, O2 mask or Trendlenberg position (p <0.001).

Discussion
Totally implantable venous access ports (TIVAP) aprovide comfort, convenience and security in the application of chemotherapy, which when administered via peripheral vein, may present complications, such as phlebitis, pain and even more severe consequences, like skin necrosis and limb compartment syndrome due to extravasation of medication.5 These complications cause unnecessary concern, affecting the quality of life of cancer patients. Unlike in externalized tunneled
catheters (e.g., Hickman catheter), central venous arm ports show a lower infection rate, long duration and better quality of life which is important, especially in the often immunocompromised patient.6
The sites most commonly used for the insertion of these devices are currently the veins of the superior vena cava system (internal jugular and subclavian) with the reservoir positioned in the anterior chest region. These techniques are proven safe and have become even
more effective after the systematic use of ultrasound, with a significant reduction in cannulation failure rates, inadvertent puncture of carotid, hematoma formation, hemothorax or pneumothorax when compared to the technique based on the use of anatomical landmarks.7
Brachial insertion ports are safely implanted in peripheral veins, especially the basilic vein, with easy maintenance and low morbidity, since the rates of severe perioperative complications related to puncture site or pneumothorax and hemothorax are zero. Risks associated with catheter fracture between the clavicle and the first rib (pinch-off syndrome) also appear to be reduced by the use of this technique.4
Devices with the reservoir implanted in the arm offer an interesting alternative for patients with gross tumors or exposure to radiation therapy in cervical and/ or anterior chest regions which contraindicate the port implantation in the conventional position, avoiding femoral vein catheterization, greatly associated with infectious complications. Another possible advantage of the brachial port insertion includes better cosmetic results, avoiding scars in more exposed and visible regions.4
In our study, an excellent technical success rate of
100% was observed. Similar success rates were presented in a study with 299 patients undergoing radiological port placement via the jugular or subclavian vein, respectively undergoing radiological arm port placement in 109 patients. This study confirms already published data showing higher technical success.8

During intraoperative period the group of central approach required O mask and Trendlenberg positioning was mandatory. The face was covered by towels making the patient irritable while in the peripheral approach this was not required and the patient could breathe freely without covering his face. Although the incidence of accidental intraoperative complications, such as arterial puncture pneumothorax, and haemothorax are low in other reports in the literature (pneumothorax, 1.5%-
3.1%; arterial puncture, 3.1%-4.9%; total, 6.2%-
10.7%),9 it cannot be eliminated completely in jugular approach unless the risk is structurally excluded. In this regard, upper arm port implantation has several physical advantages. First, because of anatomical reasons, these complications didn’t occur in upper arm implantation. Second, unlike subclavian / internal jugular /femoral puncture, no landmark method for the upper arm exists, forcing an operator to use ultrasound, eliminating arterial puncture risk. In the present study, the difference between the incidences of these preprocedural complications was significant.10
The overall post-operative complication rate was the same in both groups ‘’Pinch-off syndrome’’ didn’t occur during upper arm implantation because of anatomical reasons. Distal catheter migration from the puncture point is also unlikely to occur in the straightforward upper arm lines because there are no steep turning sections causing tension from an elastic restoring force.
Such parts are usually observed in internal jugular procedures.2
The most frequent observed late complications in this study were vein thrombosis (6%) infection (8%) and Cath occlusion (6%). Publications regarding pectoral ports report lower rates of thrombotic complications than arm ports. The reason for higher thrombotic complications may lie in the longer distance and the smaller diameter of the passed vessels if the port is placed peripherally and this would be a potential disadvantage of this technique when compared to cervical insertion.
Knriakose et al. reported a higher incidence of arm venous thrombosis in patients with a peripherally placed port (11.4%) than in those with a chest port (4.8%). The incidence of arm venous thrombosis in our series (12%) is compatible with that of peripherally placed port.11 The only thrombotic complication was a superficial thrombophlebitis of the basilic vein, confirmed by Doppler ultrasound. After one week of full anticoagulation, patients have complete remission of the edema, and the treatment was continued for 3 months with no complications. The catheter remained functioning throughout the treatment period. There are currently no definite recommendations or guidelines for the use of prophylactic anticoagulation therapy to prevent thromboembolic complications.12
Cath infection and occlusion were observed, describing this circumstance to an inadequate handling of the port during the service interval; maybe more effort should be made to teach medical staff how to use the devices safely and properly, with emphasis on how to work strictly sterile when puncturing the port and on blocking the system with heparinized sodium chloride potential problem in the longterm management of the port.13
No complications regarding a breakdown of the port system and there was minimal drug leak (one case only) occured noted over the observation period of 1 to 24 months in our series. This is probably because the main users of TIVP at our institute were all highly trained in the use of several types of TIVP systems, and thereby mechanical damage to the port system could be avoided.8
We found no significant differences for some questions addressed in the questionnaire compared to the findings of Goltz et al.14 76% from peripheral approach preferred this site compared to (12%) of central approach, (28%) of patients especially females in central approach said that it would be better if they have their port peripherally compared to (2%) in the peripheral approach who want it on the chest. They said that upper arm implantation does not leave scars on the neck or chest, which may prevent patients from wearing wide-open neck clothes because of cosmetic concerns.
Moreover, in our study the patients complained less
about any unpleasant sensation associated with the port, and reported lower impact caused by the device on daily activities, such as moving the arm and wearing clothes. The level of satisfaction with the aesthetic results observed among patients in our study was higher (p=0.0001).
Conclusion
In conclusion, for patients with peripheral veins no longer able to accept an indwelling needle, TIVP is safe and suitable for long-term use for chemotherapy. The brachial port implantation is a feasible option with low surgery risk, low intraoperative, similar rates of postoperative and late complications compared to existing data and can provide safety and comfort benefits to both medical professionals and cancer patients.
Our results showed a high level of patient satisfaction on quality of life with the brachial catheter insertion, and almost all the patients analyzed would recommend this device to others.
Our study demonstrated only an initial evaluation of a technique not often used in our practice, but that can be employed safely and presents satisfactory results.
We hope that this procedure will become more common and eventually be validated in prospective multicenter randomized clinical trials regarding its noninferiority or superiority to the internal jugular procedures with respect to safety, maintenance of quality of life, and cost-effectiveness.
