Peripherally inserted central catheter (PICC) is a widely used technique in oncology chemotherapy, characterized by safety, reliability, and long dwell time. However, a catheter can break due to various causes. When an acute rupture occurs, it always lead to sever complications which may threaten patients\' safety and potentially result in medical disputes. In this study, we collected and analyzed 3 cases of PICC line breakage causing drug leakage in our hospital from 2018 to 2023. All these 3 cases were postoperative breast cancer patients accepting chemotherapy, with 2 cases involving external partial breakage and 1 case involving internal partial breakage. Due to timely and appropriate management, no acute rupture occurred. We propose some ideas such as selecting high-quality catheter materials and avoiding over extension or repeated bending are crucial in preventing PICC line breakage. In addition, we also recommend establishing a standardized and scientific management pattern of PICC to ensure the safety and effectiveness of its clinical application, including comprehensive assessment, \"four-element\" intervention, and continuous evaluation.

Intravenous injection of pulverized tablet formulations intended for oral use may lead to pulmonary foreign body granulomatosis, a rare and serious condition. This case report details an unusual case of pulmonary micronodular disease resulting from the injection of crushed hydrocodone bitartrate and acetaminophen tablets via a peripherally inserted central catheter (PICC). A 62-year-old female on total parenteral nutrition presented with progressive dyspnea on exertion. A high-resolution CT scan revealed bilateral diffuse pulmonary nodules. Bronchoscopy and lung biopsy confirmed the presence of granulomatous inflammation with foreign-body giant cells, consistent with a foreign-body reaction. A detailed history uncovered that the patient had been administering crushed oral medication through her PICC line for better pain control. This case report adds to the literature by documenting the severe consequences of PICC line misuse and enhancing the understanding of lung granulomatous reactions from foreign materials.

UNASSIGNED: Peripherally inserted central catheters (PICCs) are frequently utilized for extended intravenous treatments. However, complications such as incorrect placement into the azygos vein can result in significant health issues. A thorough understanding of these aspects is crucial to enhance the safety and effectiveness of PICC procedures, thereby improving patient care outcomes.
UNASSIGNED: The research was conducted on a cohort of 12 patients who experienced PICC malposition into the azygos vein. Systematically reviewed information on classification, imaging manifestations, potential influencing factors, and methods for identification, prevention, and management.
UNASSIGNED: The analysis uncovered two PICC malposition classifications within the azygos vein, each with unique imaging characteristics. It also pinpointed several factors influencing malposition, offering valuable insight into potential risks. Moreover, it established effective detection methods, underscoring the significance of imaging techniques. Additionally, it outlined strategies for preventing and managing PICC malposition in the azygos vein, enhancing overall comprehension of the issue.
UNASSIGNED: The findings emphasize the importance of taking a proactive stance to avoid malposition and stress the necessity of prompt and precise intervention when malposition does happen, thereby enhancing the safety and effectiveness of PICC processes.

Onasemnogene abeparvovec (OA) is the approved intravenous gene therapy for the treatment of spinal muscular atrophy (SMA). A functional copy of the human SMN1 gene was inserted into the target motor neuron cells via a viral vector, AAV9. In clinical trials, OA was infused through a peripheral venous catheter, and no data are available on central catheter use. Recently, we had a case where OA was administered directly into the right atrium via a peripherally inserted central catheter (PICC) instead of a peripheral line, as recommended. The patient was a female child aged 4 months, diagnosed as SMA type I. For practical reasons, a dose of OA according to the weight of the patient (1.1 × 1014 vectorial genomes/kg) was administered via PICC in 1 h, as the product information recommends. The drug was well tolerated, with no hypersensitivity reactions or initial elevation of transaminases or other adverse effects. To our knowledge, this is the first case reported where OA was administered via a central line. This type of administration is not contraindicated, but it is not specifically contemplated or recommended. It is unknown whether central line administration could have any implications for transduction efficiency and immunogenicity. Future studies should clarify these aspects, as each gene therapy has a specific optimal dose recorded that depends on the site and route of administration of the drug, the AAV variant and the transgene.

Peripherally inserted central catheters are widely used in patients with extensive burns, with the guidelines recommending insertion through unburned skin. This case report describes a patient who was burned over 88% of their surface area and suffered severe inhalation injury. For him, the popliteal vein was the only vein on unburned skin available for catheter catheterization. Based on evidence, we successfully placed a peripherally inserted central catheter through the popliteal vein under ultrasound while the patient was in the prone position and avoided associated complications.

BACKGROUND: Peripherally inserted central catheters (PICCs) are an essential infusion route for oncology patients receiving intravenous treatments, but lower extremity venipuncture is the preferred technique for patients with superior vena cava syndrome (SVCS). We report the case of a patient with a lower extremity PICC ectopic to the ascending lumbar vein, to indicate and verify PICC catheterisation in the lower extremity is safe and feasible. And hope to provide different perspectives for clinical PICC venipuncture to get the attention of peers.
METHODS: On 24 August 2022, a 58-year-old male was admitted to our department due to an intermittent cough persisting for over a month, which worsened 10 d prior. Imaging and laboratory investigations suggested the patient with pulmonary malignancy and SVCS. Chemotherapy was not an absolute contraindication in this patient. Lower extremity venipuncture is the preferred technique because administering upper extremity venous transfusion to patients with SVCS can exacerbate oedema in the head, neck, and upper extremities. The patient and his family were informed about the procedure, and informed consent was obtained. After successful puncture and prompt treatment, the patient was discharged, experiencing some relief from symptoms.
CONCLUSIONS: Inferior vena cava catheterisation is rare and important for cancer patients with SVCS, particularly in complex situations involving ectopic placement.

UNASSIGNED: A peripherally inserted central catheter (PICC) is a specialized type of long-term intravenous catheter commonly employed for administering chemotherapy. The operation and management of PICC should exclusively be carried out by trained healthcare professionals equipped with the requisite knowledge of anatomy, procedural technique and patient care. Persistent left superior vena cava (PLSVC) is a vascular malformation which is typically asymptomatic in clinical presentation, almost always identified during invasive surgery or imaging examinations.
UNASSIGNED: Herein, we detailed a case involving a breast cancer patient whose PLSVC was identified during the placement of PICC because of the negative P-wave in electrocardiogram (ECG). Subsequent examination, including chest x-ray imaging, postoperative enhanced CT of the chest, ECG, and consultation with an experienced imaging physician confirmed that the patient\'s variant type was PLSVC type I. 2160. Removal of the catheter was deemed unnecessary, as the catheter tip was appropriately positioned and no other concomitant cardiovascular malformations were detected.
UNASSIGNED: The PLSVC is a vascular anomaly and is relatively uncommon within the general population. The operator should possess a thorough familiarity with the potential anatomical variations of left superior vena cava, and specialized case profile should be established for patients diagnosed with PLSVC.

This report presents a case involving a 21-year-old male patient with acute promyelocytic leukemia, where the peripherally inserted central catheter (PICC) tip location was diagnosed differently using ultrasound and computed tomography. The PICC was inserted into the left upper arm via the basilic vein. Echocardiography performed in the left lateral recumbent position suggested the PICC tip to be in the right atrium, deepest at the level of the tricuspid annulus. However, trans-catheter contrast-enhanced echocardiography, performed with a different posture involving left shoulder abduction and slight external rotation, revealed the tip to be at the cavo-atrial junction. Additionally, chest computed tomography, conducted in the supine position with raised arms, indicated the tip to be located at the upper one-third of the superior vena cava. These contradictory diagnoses can be attributed to the use of different body postures during the assessments. Considering the clinical efficacy and safety, it is crucial to fully consider the influence of multiple postures on PICC tip location during placement and determination. We recommend incorporating at least two opposite extreme daily postures to assess the nearest and farthest positions of the tip, ensuring effective and safe PICC placement and reducing the risk of complications.

BACKGROUND: Peripherally inserted central catheters (PICCs) are typically placed under fluoroscopy. We used a magnetic tracking and electrocardiogram-based tip confirmation system for insertion of a PICC insertion in a morbidly obese patient at the bedside.
METHODS: A 53-year-old female with severe obesity (height, 160 cm; weight, 217 kg; BMI, 84.8 kg/m2) was admitted to the intensive care unit. Both bilateral, inguinal, and cervical regions were covered with an excess of adipose tissue, making it difficult to place a central venous line. Since transferring her to fluoroscopy seemed dangerous, a PICC was inserted using Sherlock 3CG® TCS at the bedside. Magnetic sensor guidance failed due to the thick subcutaneous tissue her precordium, but intracavity electrocardiography could direct the tip to an appropriate position.
CONCLUSIONS: We experienced bedside insertion of a PICC into a patient with BMI of 84.8 kg/m2 patient using a Sherlock 3CG® TCS. Since the interaction between Sherlock 3CG® TCS and body habitus has not been investigated, further reports are needed.

BACKGROUND: Although the use of a peripherally inserted central catheter (PICC) has many advantages for the treatment of neonates, catheter malposition may result in serious complications that could be life-threatening. We report the case of a 10-day-old neonate with cardiac tamponade secondary to a PICC line who was successfully treated by pericardiocentesis.
METHODS: An Iranian (Asian) preterm male neonate was born by Cesarean section with a birth weight of 1190 g and a first-minute Apgar score of 7. Based on an increased respiratory distress syndrome (RDS) score from 4 to 7, resuscitation measures and intubation were performed at the neonatal intensive care unit (NICU). On day 3 after birth, a PICC line was inserted for parenteral therapy. A chest X-ray confirmed that the tip of the PICC line was in the appropriate position. Mechanical ventilation was discontinued 72 h post-NICU admission because of the improved respiratory condition. On the day 10 post-NICU admission, he suddenly developed hypotonia, apnea, hypoxia, hypotension, and bradycardia. Resuscitation and ventilation support were immediately started, and inotropic drugs were also given. Emergency echocardiography showed a severe pericardial effusion with tamponade. The PICC line was removed, and urgent pericardiocentesis was carried out. The respiratory situation gradually improved, the O2 saturation increased to 95%, and vital signs remained stable.
CONCLUSIONS: Dramatic improvement of the neonate\'s clinical responses after pericardial drainage and PICC removal were suggestive of PICC displacement, pericardial perforation, and cardiac tamponade.
