Objective: The objective is to explore the application of computed X-ray tomography (CT) imaging technology in peripherally inserted central catheter (PICC), and to propose a more effective method for PICC catheterization. Method: In this study, 69 subjects are divided into the observation group (X-ray and CT) and the control group (X-ray). The guiding effect of CT images on PICC tube placement in complex cases is compared. In this study, CT localization of the superior vena cava–caval-atrial junction (CAJ) is used as the gold standard. The position relationship of carina-CAJ and carina-PICC catheter tip is measured and analyzed by CT image and chest radiography (CXR) image, providing scientific basis for PICC tip imaging. Results: After this study, the tip of the catheter should be 1/3 of the middle and lower part of the superior vena cava, about 3 cm above the junction of the right atrium and the superior vena cava, and in the upper part of the diaphragm of the inferior vena cava, so that it cannot enter the right ventricle or the right atrium. The best position of the tip of the catheter is near the junction of the superior vena cava and the right atrium. The average vertical distance between the tracheal carina and CAJ is 4.79 cm. Conclusion: CT and X-ray examination can effectively determine the location of the tip of PICC catheter in cancer chemotherapy patients, but the clarity of X-ray examination is missing. It is suggested to adopt CT examination, and further adopt and promote it.

Abstract Two preliminary studies were conducted to determine feasibility of using the electrocardiography (EKG) method to determine terminal tip location when inserting a peripherally inserted central catheter (PICC). This method uses the guidewire inside the catheter (or a column of saline contained in the catheter) as an intracavitary electrode. The EKG monitor is then connected to the intracavitary electrode. The reading on the EKG monitor reflects the closeness of the intracavitary electrode (the catheter tip) to the superior vena cava (SVC). The studies revealed that the EKG method was extremely precise; all tips placed using the EKG method and confirmed using x-ray were located in the superior vena cava. In conclusion, the EKG method has clear advantages in terms of accuracy, cost-effectiveness, and feasibility in conditions where x-ray control may be difficult or expensive to obtain. The method is quite simple, easy to learn and to teach, non-invasive, easy to reproduce, safe, and apt to minimize malpositions due to failure of entering the SVC.

We report a case of primary malposition of a PICC inserted by guidewire replacement in the emergency room. Intraprocedural tip location by intracavitary electrocardiography was not feasible because the patient had atrial fibrillation; intraprocedural tip location by ultrasound (using the so-called “bubble test”) showed that the tip was not in the superior vena cava or in the right atrium. A post-procedural chest X-ray confirmed the malposition but could not precise the location of the tip. A CT scan (scheduled for other purposes) finally visualized the tip in a very unusual location, the left pericardiophrenic vein.

Abstract Introduction The diagnosis of sinus venosus atrial septal defect (SVASD) is complex and requires special imaging. Surgery is the conventional treatment; however, transcatheter repair may become an attractive option. Case report A 60 year-old woman was admitted to the cardiology department with several episodes of paroxysmal atrial flutter, atrial fibrillation and atrioventricular nodal reentrant tachycardia. She reported a 10-year history of occasional palpitations which had not been studied. A transthoracic echocardiography revealed severe right ventricle dilatation and moderate dysfunction. Right volume overload appeared to be secondary to a superior SVASD with partial anomalous pulmonary venous drainage. A transesophageal echocardiography confirmed the diagnosis revealing a large SVASD of 16x12 mm (Figure A) with left-right shunt (Qp/Qs 2,2) and two right pulmonary veins draining into the right superior vena cava. Additionally, it demonstrated coronary sinus dilatation secondary to persistent left superior vena cava. CMR and cardiac CT showed right superior and middle pulmonary veins draining into the right superior vena cava 18 mm above the septal defect (Figures B and C). After discussion in clinical session, a percutaneous approach was planned to correct the septal defect and anomalous pulmonary drainage. For this purpose, anatomical data obtained from CMR and CT was needed to plan the procedure. During the intervention two stents graft were deployed in the right superior vena cava. The distal stent was flared at the septal defect level so as to occlude it while redirecting the anomalous pulmonary venous flow to the left atrium (Figure D). Control CT confirmed the complete occlusion of the SVASD without residual communication from pulmonary veins to the right superior vena cava or the right atrium (Figure E). Anomalous right superior and middle pulmonary veins drained into the left atrium below the stents. Transthoracic echocardiographies showed progressive reduction of right atrium and ventricle dilatation. The patient also underwent successful ablation of atrial flutter and intranodal tachycardia. She is currently asymptomatic, without dyspnea or arrhythmic recurrences. Conclusions In this case, multimodality imaging played a key role in every stage of the clinical process. First, it provided the diagnosis and enabled an accurate understanding of the patient’s anatomy, particularly of the anomalous pulmonary venous connections. Secondly, it allowed a transcatheter approach by supplying essential information to guide the procedure. Finally, it assessed the effectiveness of the intervention and the improvement in cardiac hemodynamics during follow-up. Abstract P649 Figure.

The article describes the types of correction of the supracardial form of abnormal drainage of the pulmonary veins. One of the methods of correcting this defect is the Warden operation, which includes: after sternotomy, connection of artificial circulation, cardioplegia, the superior vena cava is cut off, the proximal end is sutured. Next, a right atriotomy is performed, an anastomosis is formed using an autopericardial patch between the abnormal drainage and the left atrium through the ASD. Then an anastomosis is formed between the auricle of the right atrium and the distal end of the superior vena cava. As a result, blood from the abnormal pulmonary veins begins to drain into the left atrium through the ASD.

BACKGROUND: Structural features of the patients vascular system can cause unintended complications when providing vascular access and can disorient the specialist in assessing the location of the installed catheter. This study aimed to demonstrate anatomical features of the vascular system of the superior vena cava and diagnostic steps when providing vascular access in a child. CASE REPORT: Patient K (3 years old) was on planned maintenance of long-term venous access. Preliminary ultrasound examination of the superior vena cava did not reveal any abnormalities. Function of the right internal jugular vein under ultrasound control was performed without technical difficulties; a J-formed guidewire was inserted into the vessel lumen. X-ray control revealed its projection in the left heart, which was regarded as a technical complication, so the conductor was removed. A further attempt to insert a catheter through the right subclavian vein led to the same result. For a more accurate diagnosis, the child underwent computed angiography of the superior vena cava system. Congenital anomalies of the vascular system included aplasia of the superior vena cava and persistent left superior vena cava. Considering the information obtained, the Broviac catheter was implanted under ultrasound control through the left internal jugular vein without technical difficulties with the installation of the distal end of the catheter into the left brachiocephalic vein under X-ray control. CONCLUSION: A thorough multifaceted study of the vascular anatomy helps solve the anatomical issues by ensuring vascular access and preventing the risks of complications.

Background: Presented is a case of persistent left superior vena cava draining into the right atrium through coronary sinus and finally opens into right atrium. Abnormalities of the vascular system are more commonly seen due to its importance in circulation. Persistent left superior vena cava is rare but important congenital vascular anomaly. It results when the left superior cardinal vein caudal to the innominate vein fails to regress.The venous anomaly of a persistent left superior vena cava (PLSVC) affects 0.3%–0.5% of the general population. Normally the superior vena cava is a single vascular structure formed by the union of right and left brachiocephalic veins which are in turn formed by the union of internal jugular and subclavian veins of corresponding side, draining the head and neck as well as the superior extremity. Aims and Objective: To evaluate the accuracy of persistent left superior vena cava and to find out the opening of PLSVC and formations of both SVC. Materials and Methods: During routine dissection of Thorax, we have opened the thoracic cage and take out the Heart. during that we found separate SVC and then we did the study on this PLSVC in the Department of Anatomy, Jaipur National University Institute for Medical Sciences and Research Centre (JNUIMSRC) Jaipur and National Institute of Medical Sciences and Research (NIMS & R). Results: We found persistent left superior vena cava in two cadavers out of 30 cadavers (6.66%) one was 64-year-old male cadaver and another 72-year-old male cadaver. Both the vena cavae were formed as of brachiocephalic veins of the corresponding side. The persistent left superior vena cava opened into the enlarged coronary sinus that drained into the right atrium between the opening of inferior vena cava and right atrio-ventricular orifice. Conclusion: It has important clinical implications in certain clinical interventions. It may complicate placementof cardiac catheters or pacemaker leads.

Abstract This is a case report of an incidental diagnosis of persistent left superior vena cava (PLSVC). The diagnosis was suspected after a peripherally inserted central catheter (PICC) was placed and a postinsertion chest radiograph was conducted. PLSVC is a vascular anomaly that is usually diagnosed as an incidental finding. Here, we discuss the tests performed to confirm the diagnosis and the 3 variants of PLSVC. Nurses who place PICCs are likely to run across this abnormality on postinsertion chest radiograph and knowing the diagnostic test to order to confirm the diagnosis is key in expediting patient care.
