A new DC bus voltage control strategy for energy routers based on distributed coordination optimization

Abstract The types of power ports of energy routers at the side of the distribution network platform are complex and have different characteristics, which makes the operation conditions of energy routers complex and changeable. Although many pieces of literature have proposed more relevant control strategies to effectively realize the efficient and stable operation of energy routers under the two basic working conditions of grid-connected and isolated islands. However, when considering various complex operating conditions such as start-up, overload/overcharge, sudden failure of distribution network, grid-connected, and inter-island switching, the reliable operation of the existing energy routers is still faced with great challenges. In this paper, a DC bus voltage control strategy based on distributed coordination optimization is proposed for typical operating conditions of energy routers. Simulation results show that this strategy can effectively achieve the DC bus voltage control performance of energy routers under various burst operating conditions and strengthen the robustness of output voltage of energy routers under isolated islands.

Analysis of the influence of dust particles in the peanut pickup harvester with a self-designed axial-flow dust-fall box on its dust suppression performance

The atmospheric particulate pollution poses a serious threat to human health and ecological environment. The dust particle pollution caused by the operation of agricultural machinery is becoming increasingly severe and the peanut pickup harvesters are widely used in agricultural operation. Therefore, it is necessary to reduce the concentration of dust particles in the work of peanut pickup harvesters. In this study, a self-designed dust-fall box composed of multipleaxial flow cyclone tubes in parallel was integrated with the peanut pickup harvester. Based on the CFD-DPM model, simulation analysis was conducted to explore the effects of different inlet velocities, different numbers of swirling blades, and two types of exhaust port on the dust removal performance of the cyclone. The Box-Behnken design was used to determine the optimal structural parameters of the axial flow cyclone. The influence of the pressure distribution and velocity variations of the internal flow field on the dust removal efficiency of the two schemes was simulated and analyzed. Thereafter, a reasonable parallel scheme of multiple axial flow cyclone tubes in the dust-fall box was determined. The drone was used to monitor dust in peanut harvesting operations, and dust particle concentrations at 8 detection points under varying working conditions were recorded. The distribution and diffusion rules of dust in harvesting operations were explored through cluster analysis, and the test data obtained were compared with numerical calculation results to verify the accuracy of numerical calculation. The results showed that for a single axial flow cyclone, when the inlet wind speed was 6 m/s to 8 m/s and the number of swirling blades was 4, the structural parameters of the cyclone separator had significant influence on the separation efficiency. The influencing factors ranking in descending order were cylinder diameter, cylinder length, and exhaust pipe insertion depth, respectively. To be more precisely, the separation efficiency was best when the cylinder diameter was 60 mm, the cylinder length was 150 mm, the insertion depth of the exhaust pipe was 50 mm and the cone angle was 20°. It was more reasonable to use 8 axial flow cyclone tubes in parallel, and the maximum separation efficiency can reach 84.21 %. Field operations showed that the numerical calculation results were similar to the actual harvesting process. The dust particle concentration in the peanut harvesting operation equipped with a dust-fall box was always lower than 10 mg/m3. The dust particle concentration was the highest at the rear of the whole machine and the lowest near the cab. Compared conventional harvesters, the harvester with a dust-fall box reduced its dust particle concentration by 64.37 %; the concentration of 30 μm dust particles was reduced by 69.31 %; the dust particle concentration at the rear of the whole machine also effectively reduced. This study can provide reference for controlling dust emissions during peanut harvesting operations and agricultural machinery harvesting operations.

Processes and mechanisms of the evolution of container port system in the Yangtze River Delta: An analysis from spatial and network perspectives

the Yangtze River Delta (YRD) has established a large-scale container port system with seaports and Yangtze ports as the mainstay and including other riverports and dry ports, occupying a prominent position in the pattern of national and even the global shipping development. Considering the new trend that the theoretical paradigm of port research has shifted from “spatial” to “network”, and that the focus of research goes from seaports to both seaports and inland ports, this study brings the complexity and uniqueness of the development of the port system in the YRD into the picture. By analyzing the influence of globalization, specialization, marketization, transportation, and greenization on port system development and its pattern formation, this paper elaborates on the gradient process of transportation and services allocation from the coast to the riverside and then to the inland. The evolution of port system is considered to have a temporal gradient between spatial-level transportation expansion and network-level services upgrading, and it is also believed that there is a spatial gradient in logistics supply chain terminalization between coastal and inland areas. Combined with the quantitative analysis from 200 5 to 2020, after entering the stage of port regionalization in the YRD, the container volume is distributed from coastal concentration to inland decentralization at the spatial level, while at the network level, port and shipping service enterprises (PSSEs) maintain a relatively centralized distribution along the coastal areas. At the same time, container volume growth rate fluctuates down, number of PSSEs growth rate fluctuates up, which trend is notable in the seaport. Currently, port regionalization in the YRD is still incomplete; the degree of logistics supply chain terminalization of ports in inland areas is relatively low; and the synergy between spatial and network in the entire YRD region has not yet been formed. This study tries to answer the question of the relationship between different types of ports in the complex port system, which can enrich the theoretical and empirical results of port system research and guide the practice of port and shipping in the YRD.

The Representativeness of Subslab Soil Gas Collection as Effected by Probe Construction and Sampling Methods

AbstractSubslab soil gas (SSSG) samples were collected as part of an investigation to evaluate vapor intrusion (VI) into a building. The June 2015 Office of Solid Waste and Emergency Response (OSWER) VI Guide (U.S. Environmental Protection Agency [U.S. EPA] 2015) does not provide specific, detailed recommendations regarding how to collect SSSG samples. The data collected in this study will be used to provide input into future OSWER VI Guidance documents on SSSG sample collection. To this end, three different types of subslab sampling ports were constructed with various sampling techniques within a hexagon‐shaped grid in near proximity to each other. Conventional‐, Vapor Pin‐, and California‐style ports were established in duplicate for continual analysis by onsite gas chromatography‐electron capture detection (GC‐ECD). Triplicate ports were established to evaluate active and passive long‐term sampling methods to determine short range temporal differences. Active sampling methods included evacuated stainless‐steel canisters fitted with capillary flow controllers (Modified U.S. EPA Method TO‐15 [U.S. EPA 1999a]) and sorbent tubes collected using a syringe (Modified EPA TO‐17 [U.S. EPA 1999b]). The Passive sampling method used was sorbent tube samples collected following the EPA TO‐17 sampling method (Modified). This study did not identify any systematic differences in sample results between conventional, Vapor Pin, and CA‐style probes for used in SSSG sampling. The decisions for site management would probably be the same for data from any subslab port style, active or passive sampling techniques over durations less than 2 weeks.

Pengembangan Pelabuhan Perikanan “Tanjung Adikarto” di Kabupaten Kulonprogo dengan Pendekatan Arsitektur Ekologi

In the context of carrying out fisheries activities, the Tanjung Adikarto Fishing Port does not fully meet the requirements as a Coastal Fishing Port (Type C). Complete facilities such as cold storage, shops, ship maintenance and fishing equipment, as well as places for handling and processing fishery products are still not available, while several other facilities also do not meet adequate standards. In this section, the author will describe the actual conditions of the facilities at Tanjung Adikarto Port and their comparison with the standard facilities that a Coastal Port (Type C) should have. This is the first step to evaluate what needs to be improved in order to increase the capacity and feasibility of the port to support more optimal fishing activities. Observations of the existing condition of the port have revealed several problems that need attention. Buildings that are damaged and uninhabitable are one of the main issues that need to be addressed immediately. The aim is not only to ensure port operations run optimally, but also to align port activities with environmental sustainability, so that their contribution to the community's economy can be realized in a sustainable manner.

Chinese Coastal Fishing Ports Classification Based on Remote Sensing Images

Fishing ports are important fishery production platforms, and the transformation of these has had a profound impact on the fishing industry. A reasonable classification solution is crucial for scientific understanding, development, and management of fishing ports. Current research on the use of spatial distributional characterization and the construction of a classification system for fishing ports to improve their management is limited. Therefore, in this study, a fishing port classification system was constructed using remote sensing images, with fishing port boundaries accurately extracted for classification. Using graphical summarization, fishing ports were classified into five types, including inland, estuarine, shoreline, gulf, and islands. A port type identification system was also constructed based on distance from the shoreline, water area, and circulation. Finally, fishing port characteristics and differences were investigated based on spatial superposition. The results demonstrate that shoreline and gulf types are the most prevalent fishing port types along the Chinese coast, accounting for 43% and 26% of the total number of fishing ports, respectively. This provides a strong foundation for China’s fishery production, processing, and trade. Through the establishment of a comprehensive scientific classification system, fishing port management can be modernized, supporting the sustainable development and utilization of coastal zones.

Totally implantable venous ports in infants and children: a single-center retrospective study of indications and safety.

Totally Implantable Venous Access Devices (TIVADs) contribute significantly to the treatment progress and comfort of patients requiring long-term therapy. However, the procedure for implanting TIVADs, as well as its very presence, may be associated with complications. This study evaluates the indications, safety, and complication rates of venous port implantations in pediatric patients. It also explores factors influencing the occurrence of early and late complications post-implantation. The study included 383 pediatric patients treated at the Department of Pediatric Surgery, Traumatology, and Urology in Poznan between 2013 and 2020 who underwent 474 implantations of intravenous ports. Venous access was achieved using the Seldinger technique. Statistical analysis was performed using Statistica 13 with TIBCO and PQStat 1.8.2.156 with PQStat. Venous ports were used in 345 oncology patients requiring chemotherapy (90% of the total group) and in 38 children (10%) with non-oncology indications. There were 36 early complications (7.6%) and 18 late complications (3.8%), excluding infectious complications. The most common early, non-infectious complications included pneumothorax (15 patients; 3%) and port pocket hematoma (12 patients; 2.5%). The most common late, non-infectious complications observed were venous catheter obstruction (8 children; 1.7%) and port system leakage (5 children; 1%). Infectious complications occurred in 129 cases (27.2%). Children with a diagnosis of non-Hodgkin's lymphoma, acute myeloid leukemia, and acute lymphoblastic leukemia had a significantly higher incidence of port infections. Venous ports equipped with a polyurethane catheter, compared to systems with a silicone catheter, functioned significantly shorter. The Seldinger method of port implantation is quick, minimally invasive, and safe. The type of port, including the material of the port's venous catheter, and the underlying disease have an impact on the durability of implantable intravenous systems. The experience of the surgeon is related to the frequency of complications associated with the procedure.

“Great Vladivostok”: Process and Results

The “Great Vladivostok” project of the Khrushchev period is relatively little known in the history of the USSR due to political reasons. It was not only a part of Khrushchev’s great construction reform in the country but also an attempt to consolidate the influence of the Soviet Union in Eastern Asia, create a new type of port, and settle the territory of the south of the Far East with immigrants from the western part of the country. In addition, the project had several features that both Soviet and foreign scholars ignored. The authors use archival materials, oral history, and the works of researchers, including unpublished ones, in this article. The work aims to describe the realisation of the project, and its main ideas, to analyse its successes and failures.

Implementing decarbonisation measures in Norwegian ports

Despite the extensive literature on port sustainability, empirical research has so far paid limited attention to experiences with implementing measures that contribute to decarbonisation in small and medium-sized ports. This study contributes to the literature by investigating decarbonisation measures implemented by Norwegian ports, and drivers and barriers that ports associate with such efforts. We rely on a unique dataset of survey responses from 96 Norwegian port organisations, supplemented with insights from qualitative research. We find that most ports have implemented at least one measure that contributes to decarbonisation. Most prominent is shore power, followed by increased energy efficiency. We find that support from owners and surroundings is prominent in decarbonisation efforts and that political guidelines and steering from port owners are important drivers. Heterogeneity in port types and contexts implies that further empirical research is needed. This study calls for raising the role of ports in the energy transition on the political agenda.

Comparative Analysis in the Implementation of Port State Control (PSC) and Port State Measures Agreement (PSMA) in the Preventing IUU Fishing in Indonesia

Indonesia implements the prevention of IUU fishing in ports using the PSM Agreement 2009. In its implementation, the Government of Indonesia designated port of PSMA implementing by establishing four ports, namely 3 fishing ports and 1 public port. The diversity of these types of ports has an impact on differences in the implementation of foreign fishing vessels entering Indonesian jurisdiction. This research is descriptive by using normative and comparative juridical methods. The results of this study reveal that the implementation of PSC in ports uses the Tokyo MoU, and fishing ports are determined using the 2009 PSM Agreement. This difference in legal basis causes confusion in law enforcement for IUU Fishing as a party to the PSM Agreement, so that an integrated legal arrangement is needed between public ports which are the authority of the Ministry of Transportation and fishing ports which are the authority of the Ministry of Maritime Affairs and Fisheries.

A GAVeCeLT bundle for PICC-port insertion: The SIP-Port protocol.

In the last decade, a new type of brachial port has been introduced in clinical practice, the so-called "PICC-port." This is a brachial port, but inserted according to the methodologies and technologies currently adopted for the insertion of peripherally inserted central catheters (PICCs). Several studies have shown that PICC-port insertion is safe, not associated with any relevant immediate or early complication, and that the expected incidence of late complications is significantly lower if compared to "traditional" brachial ports (i.e. inserted without ultrasound guidance). Furthermore, PICC-ports yield excellent esthetic results and are associated with optimal patient compliance. This paper describes an insertion bundle-developed by GAVeCeLT, the Italian Group of Long Term Venous Access Devices, and nicknamed "SIP-Port" (Safe Insertion of PICC-Ports)-which consists of few evidence-based strategies aiming to further minimize all immediate, early, or late complications potentially associated with PICC-port insertion. Also, this insertion bundle has been developed for the purpose of defining more closely the differences between a traditional brachial port and a PICC-port. The SIP-Port bundle is currently adopted by all training courses on PICC-port insertion held by GAVeCeLT. It includes eight steps: (1) preprocedural ultrasound assessment utilizing the RaPeVA (Rapid Peripheral Venous Assessment) protocol; (2) appropriate skin antiseptic technique and maximal barrier precautions; (3) choice of appropriate vein, in terms of caliber and site; (4) clear identification of the median nerve and of the brachial artery during the venipuncture; (5) ultrasound-guided puncture and cannulation of the vein; (6) ultrasound-guided tip navigation; (7) intra-procedural assessment of tip location by intracavitary ECG or by trans-thoracic echocardiography; (8) appropriate creation and closure of the subcutaneous pocket.

Mismatch between volume and value: a new perspective on the significance of global ports

ABSTRACT To achieve high-volume and high-quality development of maritime transport and establish a port industry ecosystem, maritime stakeholders and national policymakers must recognise ports as crucial economic and trade windows. For a comprehensive and in-depth interpretation of a port, this study focuses on seaborne cargo as the entry point and proposes a methodological framework for assessing port importance. The proposed framework is based on a multi-methodological fusion and considers the relationship between the type, direction, volume, and value of the maritime cargo transported through the port, while distinguishing between the associated economic sectors, industry types, imports, exports and transhipments, and volume and value. Hence, port importance is assessed based on three dimensions: identification of the maritime transport cargo types for which the port has a comparative advantage, measurement of the port combined cargo transport capacity, and differentiation of the port type. The results reveal that seaborne cargo volumes and values are mismatched in global ports; high seaborne cargo value increases port importance to a greater degree than high seaborne cargo volume; and ports can be classified as inland serving, balanced inland and outward serving, and outward serving. These findings provide a research basis for a new port industrial-ecosystem construction strategy.

Retrofit of a 600 MW Down-Fired Pulverized-Coal Furnace for Low NOx Emission

Aiming at solving the problem of high NOx emissions of a down-fired boiler, a new combustion system has been proposed by means of the numerical simulation using Ansys Fluent. The coal-lean stream (tertiary air), which was originally mixed with a separated overfired air (SOFA) stream on the front and rear walls of the upper furnace, was relocated to the lower zone of the furnace after retrofit. The secondary-air slots were transformed into a new annular port type, which was injected into the furnace with a down-tilt angle to increase the residence time of the coal stream. Furthermore, the effect of secondary air distribution and velocity of coal stream on performance was studied. After retrofitting the combustion system, the NO emissions were effectively controlled, decreasing from 906 mg Nm−3 to 576 mg Nm−3, but the carbon content of fly ash increased from 2.46% to 5.78%. Aiming at decreasing the carbon content of fly ash, the effect of coal/primary air velocity on the arch was studied. Less carbon content in fly ash can be observed for the lower arch airflow velocity. The results showed that the NO emissions can be controlled below 595 mg Nm−3, and the carbon content of fly ash was reduced to 3.39% when the velocity was decreased to 18 m s−1.

Fuzzy and Machine Learning based Multi-Criteria Decision Making for Selecting Electronics Product

In this study, we have considered electronics product as laptop one of the essential items in digital era. The decision-making and buying processes for laptops are time consuming and fraught with competing priorities. Furthermore, machine learning is used to pick and purchase laptops using a variety of strategies. Through a questionnaire that provided them with many choices for the newest features and essential components they desire in their devices, the participants' replies were sought. The participants' responses were elicited from eighteen independent input variables: processor, ram capacity, gpu, graphics card, laptop brand, type of storage, storage size, ports, screen size, backlit keyboard, pc body, category, screen display, weight, webcam, battery life, operating system, and price range. Each of the input variables was quantified using a scale using the terms very low, low, medium, high, and very high. Five input and one output processes were designed using the Mamdani technique, a conventional fuzzy reasoning tool (FLC). To arrive at a more precise knowledge of the procedure for choosing a laptop in accordance with the user's requirements, standard fuzzy systems were employed.

Auditing state-owned enterprise through predictive analytics and function transformation

PurposeOne of the best ways to assist China is through infrastructure investment. China might become more resilient to natural calamities by pouring more money into its transport network. Analyzing the relationship between China's degree of planned expansion and the country's current network of transport hubs can help with city development estimates. A wide range of factors were taken into consideration while evaluating China's dominance and the caliber of its transportation infrastructure. Using a geographical autocorrelation model and a coupling coordination model, the dynamic link between China's adaptability and the caliber of its transportation infrastructure is examined.Design/methodology/approachChina's northwest is underdeveloped in comparison to the southeast, which has a high level of resilience and development of its transportation infrastructure. The relationship between the levels of resilience upheld by China's transport infrastructure is suggested to be coordinated.FindingsThe authors find a positive geographical autocorrelation between the degree of coupling coordination and the degree of agglomeration, despite the fact that the distance between cities increases with time. They now believe that there is a connection between an area's population density and the degree of interspousal cooperation within. The consequence is an improvement in both national security and economic prosperity. The facilities for disaster management and transportation in China have received several proposals for improvement.Practical implicationsThe authors' Practical Implications suggests that scale inefficiency is a major contributor to the relatively poor efficiency of China's primary inland river ports. Different types of inland river ports may have vastly different water system efficiencies. Input and output congestion at China's important interior river ports has reached 51%, making it very clear that massive amounts of valuable port resources are being wasted.Originality/valueMany variables, such as climate and human error, affect the total amount of goods that can be moved via inner river ports. Ports situated either higher up or lower down the same canal may perform better or worse, respectively, depending on the circumstances.

Verification of Safety for Synchronous-Reactive System Using Bounded Model Checking

Real-time embedded systems are increasingly applied in safety-critical areas, so guaranteeing the correctness of such systems by means of formal methods becomes particularly important. In this paper, we propose an optimized bounded model checking (BMC)-based formal verification approach for the verification of safety for synchronous-reactive (SR) models, which are often used to design systems with complicated control logic, especially the real-time embedded control systems. This method is based on the tackling of a series of challenging problems including the management of the logical clock, encoding of the contained ports, representation of the data types of ports, descriptions of behaviors of various components in a considered model, and formal consideration of the fixed-point semantics. We have implemented this proposed method in the prototype Ptolemy-Z3, and integrated this tool into the Ptolemy II environment. In addition, the experimental evaluation on 22 SR models has shown that our method performs better than the existing automatic verification method in Ptolemy II.

Towards a Reference Architecture for Cargo Ports

Cyber-Physical Systems (CPS) are physical systems whose operations are coordinated, monitored, and controlled by computing and communication functions. These systems are typically heterogeneous, including Internet of Things and information technology subsystems, and can present a myriad of implementation details, making them very complex systems. An important type of CPS is a maritime container terminal (cargo port), which is a facility where cargo containers are transported between ships and land vehicles for onward transportation and vice versa. A cargo port performs four basic functions: receiving, storing, staging, and loading for both import and export containers. We present here process patterns that describe the functional aspects of cargo ports and a pattern that describes their structural properties (patterns are encapsulated solutions to recurrent problems). These patterns describe semantic aspects found in any cargo port and can be adapted to describe other CPSs. We decompose these process patterns into use cases that describe their interactions with the system. We then integrate the process patterns with structural patterns to assemble a partial reference architecture (RA) that shows the interactions of all the patterns while also indicating the typical stakeholders found in all ports. We validate the proposed reference architecture, highlighting its theoretical and practical value. Software and system designers of cargo ports need to start from a conceptual and abstract view that is subsequently refined to add more details. The use of reference architectures and patterns is an effective way to organize and describe the functional and non-functional aspects of a system, as well as to unify the design of all its aspects. This is, until now, the only published RA for cargo ports, and it can be a useful guideline for the designers of any type of cargo port.

The Evolution of the Waterfront Utilization and Sustainable Development of the Container Ports in the Yangtze River: A Case Study of the Yangtze River Delta

Waterfront resources are an important support system for the social and economic development within the region along the Yangtze River. Container ports are an important component of the Yangtze River port system, as well as for the growth point of waterfront utilization. Based on the summary of remote sensing images and relevant data, this paper calculates the waterfront utilization of the container ports along the Yangtze River in the Yangtze River Delta (YRD), analyzes the waterfront organization pattern and change characteristics, and puts forward the enlightenment and countermeasures for the sustainable development of the port waterfronts. Extending the study of port resources from coastal areas to inland areas is an academic contribution of this paper. At the same time, it has practical significance for the high-quality development of port and shipping and the development and protection of land resources along the Yangtze River. In the YRD, the waterfront utilization of container ports has increased along the Yangtze River, showing a decrease from downstream to upwards, and it has formed dense zones attached to the central cities and major manufacturing bases. The ports with higher length of waterfront are mostly located in the shipping central cities and the Yangtze River estuary. The development direction of container ports is large-scale and specialized. The utilization of the container port waterfront is approaching the periphery of the city and areas with convenient transportation. The utilization of container port shorelines will be close to the periphery of the city and convenient transportation areas. The container port waterfronts occupy the ecological reserve, and the conflicts are expanding with the development of shipping, mainly distributed in the Yangtze River estuary. Based on the empirical analysis, this paper puts forward four enlightenments. First, the exploitation and utilization of the port waterfront has experienced multiple stages of “exploitation—conflict—mitigation”. With the transformation of productive waterfront utilization, the pattern of sustainable development along the Yangtze River has changed. Secondly, the conflict between waterfront utilization and protection is inevitable. Additionally, it is necessary to face up to the temporary rapid rise of encroachment on the reserve. Third, through the horizontal coordination of the port system along the river, the original focus on the hub cities will be transferred to the comprehensive consideration of the port cities in the whole region, and the waterfront load of different types of container ports can be balanced. Fourth, the Yangtze River Delta integration mechanism can solve the barriers between higher and lower levels or between different departments and cities.

Organization of river-sea container transportation in the Yangtze River: Processes and mechanisms

Port systems' regionalization is driven by inland port construction and shipping logistics. Among them, riverports are unique inland ports that are connected by seaport systems and contribute to a river-sea container transportation (RSCT) organization. Through a case study of the Yangtze River, this study conceptualizes RSCT based on the “spatial-network” perspective, and the driving forces pertaining to globalization, informatization, marketization, and greenization are examined. Further, we explore the trajectory of port regionalization and supply chain terminalization between coastal and inland areas, and analyze the multiscale mechanism of transportation and service development among ports considering spatial effects. The results suggest that a significant temporal gradient exists in port regionalization between the coast and inland regions. Logistics supply chain terminalization, a component of regionalization, forms and develops only during the growing stage of regionalization. Currently, the Yangtze River port system is regionalizing and being terminalized, contributing to spatial variation between the size and capacity of different types of seaports and inland ports in providing container transportation and logistics-derived services. The framework is validated by a quantitative empirical analysis based on container barge route data and shipping service enterprise data, thus confirming the evolution process from coastal concentration to inland decentralization for both. The study findings indicate that transportation's decentralization is more significant at the macro level, and that the service cannot narrow the gap between coastal and inland areas significantly with the current development of port systems in the Yangtze River. The interaction between “spatial” and “network” has only improved in seaports, and the nexus of the transportation and logistics supply chains has not yet been formed at the macro level. This study contributes to the literature on port regionalization from the spatial network perspective and provides insight into the relationship between seaports and inland ports in a complex port system.

An unusual cause of chest pain.

A 78-year-old female with a history of lymphoma presented to the emergency department (ED) because of chest discomfort. A chest x-ray was performed and revealed the diagnosis. As shown in Figure 1, the patient's Port-A-Cath fractured and part of it was displaced to the right heart (Figures 1 and 2). The discontinuity was noted at the level of the left first rib and clavicle. The mid and distal portion migrated and was seen within the distal superior vena cava, right atrium, and possibly projecting into the right ventricle. The decision was made to admit the patient to conduct endovascular retrieval. One of the rare complications of a Port-A-Cath placement is its fracture and displacement into the heart. The most common site of displacement is at the superior vena cava-right atrium junction, and it can further embolize into the right ventricle.1 This complication is rare, with a reported incidence of 0.4%–1.8% and 66% of patients developing the fracture within 1 year.2 Some causes that might lead to a port fracture and displacement include the type of port used, the site of placement, and the duration of catheter use.2 An endovascular approach is used to retrieve the fractured catheter.3 Knowledge of this complication can help emergency physicians when evaluating a post-chemotherapy patient because catching it early can prevent fatal complications such as cardiac arrhythmias and septic embolization.3
