Totally implanted venous access port (TIVAP) systems provide adequate quality of care and life, especially for oncology patients. Long-term vascular access is very important and easy to perform, but in some clinical situations, if patients have a superior caval system occlusion, femoral insertion may be the only option. We present a case of a 70-year-old colorectal adenocarcinoma patient diagnosed with subclavian vein hypoplasia. Her care team decided intraoperatively to implant a port system by the right femoral access...

A 47-year-old woman with a history of radiation enteritis and implantation of a central venous port was admitted to our intensive care unit(ICU) suffering from high fever. She was diagnosed with active infective endocarditis due to catheter-related blood stream infection. Although echocardiography showed a large vegetation on the mitral valve, surgical therapy was postponed for 5 weeks because of intracranial hemorrhage infarction. On the 3rd day after mitral valve repair, she developed consciousness disturbance and computed tomography(CT) revealed acute subdural hematoma of the posterior cranial fossa...

BACKGROUND: Combined latissimus dorsi and prosthetic reconstruction is a useful reconstructive option in patients with a history of breast radiation who are not good candidates for abdominally based autologous reconstruction. One difficulty, particularly in obese patients, is that the thickness of the flap can impair port localization, increasing the risk of inadvertent puncture during expansion. The authors sought to investigate the upper limits of tissue thickness at which tissue expansion can be reliably performed...

BACKGROUND: Cytoreductive surgery with hyperthermic intraperitoneal chemotherapy (CRS-HIPEC) is an appropriate treatment for select patients with peritoneal carcinomatosis. While most commonly performed through an open incision, the laparoscopic approach has been reported and offers short-term benefits. A robotic-assisted approach for carcinomatosis of gastrointestinal origin, however, has not yet been described. METHODS: We report our approach to robotic-assisted CRS-HIPEC for a patient with a perforated appendiceal mucocele...

BACKGROUND: Catheter-related bloodstream infection (CRBSI) is one of the most frequent complications in patients with cancer who have central venous catheters (CVCs) implanted and is associated with substantial morbidity and mortality. Taurolidine is a non-antibiotic agent with broad-spectrum antimicrobial activity, which has been used as a lock solution to prevent CRBSI in some settings. However, little is known about its usefulness in high-risk adult neutropenic patients with cancer...

INTRODUCTION: Intravascular or catheter embolization of a foreign body, either by fracture or migration, is a rare condition, occurring in approximately 1%. This study is focused on the migration of catheters since they represent the majority of cases of embolization. We present one of the largest published series of removal of foreign bodies with endovascular techniques. The objective of the present study is to demonstrate the different locations where foreign bodies, in most cases catheters, can reach, the technique used to remove them and the affected population...

Superior vena cava syndrome (SVCS) represents undoubtedly a rare life-threatening condition. Herein, we present a rare case of a 69-year-old woman, with a history of hepatic flexure tumor and an indwelling central venous port, presenting with acute signs and symptoms of SVCS due to thrombosis of the catheter. The patient was treated with intravenous anticoagulation and fibrinolytic therapy and showed regression of symptoms. It is reported that central venous catheters are routinely used in clinical practice mainly in oncological cases for chemotherapy, parenteral nutrition or dialysis...

BACKGROUND: Three types of central venous access devices (CVADs)-peripherally inserted central catheters (PICCs), skin-tunnelled central catheters (Hickman-type devices), and implantable chest wall Ports (Ports)-are routinely used in the intravenous administration of anti-cancer treatment. These devices avoid the need for peripheral cannulation and allow for home delivery of treatment. Assessments of these devices have tended to focus on medical and economic factors, but there is increased interest in the importance of patient experiences and perspectives in this area...

The purpose of this study was to model the metallic port in breast tissue expanders and to improve the accuracy of dose calculations in a commercial photon treatment planning system (TPS). The density of the model was determined by comparing TPS calculations and ion chamber (IC) measurements. The model was further validated and compared with two widely used clinical models by using a simplified anthropomorphic phantom and thermoluminescent dosimeters (TLD) measurements. Dose perturbations and target coverage for a single postmastectomy radiotherapy (PMRT) patient were also evaluated...
