Abstract

An entry vessel is crucial for intravenous port implantation. A safe alternative entry vessel that can be easily explored is crucial for patients without feasible cephalic vein or for those who need port reimplantation because of disease relapse. In this study, we tried to analyze the safety and feasibility of catheter implantation via the deltoid branch of the thoracoacromial vein. From March 2012 to November 2013, 802 consecutive oncology patients who had received intravenous port implantation via the superior vena cava were enrolled in this study. The functional results and complications of different entry vessels were compared. The majority of patients (93.6%) could be identified as thoracoacromial vessel. The deltoid branch of the thoracoacromial vein is located on the medial aspect of the deltopectoral groove beneath the pectoralis major muscle (85.8%) and in the deep part of the deltopectoral groove (14.2%). Due to the various calibers employed and tortuous routes followed, we utilized 3 different methods for catheter implantation, including vessel cutdown (47.4%), wire assisted (17.9%), and modified puncture method (34.6%). The functional results and complication rate were similar to other entry vessels. The deltoid branch of the thoracoacromial vein is located in the neighborhood of the cephalic vein. The functional results of intravenous port implantation via the deltoid branch of the thoracoacromial vein are similar to other entry vessels. It is a safe alternative entry vessel for intravenous port implantation.

Abstract

Background: Our objective is to report on two centers' experience of intra-operative management of major vascular injury during single-port video-assisted thoracoscopic (SPVATS) anatomic resections, including bleeding control techniques, incidence, results, and risk factor analysis.Methods: Consecutive patients (n = 442) who received SPVATS anatomic lung resections in two centers were enrolled. The different clinical parameters studied included age, previous thoracic surgery, obesity (BMI > 30), tumor location, neoadjuvant therapy, and pleural symphysis. In addition, peri-operative outcomes were compared between the groups, with or without vessel injury.Results: There were no intra-operative deaths in our study. Overall major bleeding incidence was 4.5%, whereby 70% of major bleeding episodes could be managed with SPVATS techniques. In order to determine risk factors possibly related to intra-operative bleeding, we used case control matching to homogenize our study population. After case control matching, pleural symphysis was significantly related in the univariate (p = 0.005, Odds ratio 4.415, 95% CI 1.424-13.685) and multivariate analysis (p = 0.006, Odds ratio 4.926, 95% CI 1.577-15.384). Operative time (p < 0.001), blood loss (p < 0.001), and post-operative hospital stay (p = 0.012) were longer in patients with major vascular injury. There were no differences in 30-day mortality and 90-day morbidity.Conclusions: In summary, major intra-operative bleeding episodes during SPVATS anatomic lung resections are acceptable and most such bleeding episodes can be safely managed with SPVATS techniques.

Abstract

Abstract: All available conventional ports share a common design, including catheter, locking nut, and port body, and all share two sites of structural weakness. One site is the junction between the locking nut and the proximal end of the catheter. The other site is the catheter fixation site between the locking nut and the protruding stud of the connecting tube. To overcome these shortcomings, we designed a new type of intravenous port which combines the connecting tube into one piece. The aims of this study were to test the mechanical characteristics of the new design and assess its safety in animal study. The prototype of the preattached port was manufactured from biocompatible materials, including PEEK, silicone and polyurethane. All components were assembled with biocompatible glue and mechanical and safety tests were performed to determine the mechanical strength, and tissue reaction of surrounding soft tissue and entry vessels. The mechanical tests showed the new design would not lead to catheter fracture in the oscillation test. The traction test showed significant peak load (18.75 ± 3.29 vs. 26.61 ± 1.75 N; p = 0.036) because of the difference in catheter extension capacity (26.57 ± 4.28 vs. 47.93 ± 2.45 mm; p = 0.012). Significantly smaller endurable injection pressure was identified in the prototype. (90 ± 20 vs. 177.5± 9.48 psi; p = 0.01) The safety test showed good tolerance in beagle dogs and led to no intravascular thrombus and minimal reaction in surrounding tissues. The new prototype preattached port showed good mechanical strength and overcame two potential structural weakness points. The integrated fixation design not only reduced the dimensions of the port device but also provided a greater injection area compared to current designs. It did not cause intravascular thrombosis and produced minimal tissue reaction in surrounding soft tissue, as identified by autopsy. The new design of the fixation device could serve as the basis for the next generation of intravenous ports. © 2017 Wiley Periodicals, Inc.
