Abstract Background A persistent left superior vena cava (PLSVC) is the most common congenital anomaly of the thoracic venous return. Case Description During atrial septal defect repair, a pulmonary artery (PA) catheter was placed via the left internal jugular vein. Although placement of the PA catheter in the main PA was confirmed by transesophageal echocardiography, the central venous pressure (CVP) waveform was abnormal. Intraoperatively, the PA catheter was seen exiting the coronary sinus with the CVP port within the coronary sinus. Conclusions The diagnosis of PLSVC is discussed and the differential diagnosis of the abnormal “ventricular” pattern of the CVP waveform is reviewed.

Background. A conventional centrally inserted central catheter (CICC) is frequently used to measure central venous pressure (CVP) to monitor the cardiocirculatory status of patients. The tip of the totally implanted port (TIP) is inserted at the same location in the superior vena cava as that of a CICC, and the TIP has been implanted in many patients with cancer. Measurements of CVP using CICC (CICCP) and TIP (TIPP) may be closely related. Material and Methods. Ten patients with TIPs in an intensive care unit were prospectively studied, and 121 records of 4536 paired CICCP and TIPP measurements were collected. A bench test in a static or dynamic setting was performed, and 598 paired measurements taken using CICC and TIP were recorded. Results. The measurement of TIPP was highly correlated with that of CICCP in patients with cancer, especially those in a calm state. Patients with a calm state and ≥3 consecutive identical TIPP were recorded (≥30 seconds), and 90% of the mean difference between CICCP and TIPP was ≤2 mmHg. The pressure measurements recorded using CICC and TIP were identical in both the static and dynamic bench tests. Conclusions. TIP may be an alternative to CICC for measuring CVP.

The health care system in Peru treats 15,000 dialysis patients annually. Approximately 45% of patients receive therapy using catheters. The incidence of catheter-induced superior vena cava (SVC) occlusion is increasing along with its associated significant morbidity and vascular access dysfunction. One of the unusual manifestations of this complication is bleeding “downhill” esophageal varices caused by reversal of blood flow through esophageal veins around the obstruction to the right atrium. Herein is presented the case of an 18-year-old woman on hemodialysis complicated by SVC occlusion and bleeding esophageal varices who underwent successful endovascular recanalization of the SVC. Bleeding from “downhill” esophageal varices should be considered in the differential diagnosis of dialysis patients exposed to central venous catheters. Aggressive endovascular treatment of SVC occlusion is recommended to preserve upper extremity access function and prevent bleeding from this complication.

Patients who present with acute cardiovascular compromise require haemodynamic monitoring in a critical care unit. Central venous pressure (CVP) is the most frequently used measure to guide fluid resuscitation in critically ill patients. It is most often done via a central venous catheter (CVC) positioned in the right atrium or superior or inferior vena cava as close to the right atrium as possible. The CVC is inserted via the internal jugular vein, subclavian vein or via the femoral vein, depending on the patient and their condition. Complications of CVC placement can be serious, so its risks and benefits need to be considered. Alternative methods to CVC use include transpulmonary thermodilution and transoesophageal Doppler ultrasound. Despite its widespread use, CVP has been challenged in many studies, which have reported it to be a poor predictor of haemodynamic responsiveness. However, it is argued that CVP monitoring provides important physiologic information for the evaluation of haemodynamic instability. Nurses have central roles during catheter insertion and in CVP monitoring, as well as in managing these patients and assessing risks.
