Rare complication of a dialysis catheter insertion

Persistent Left Superior Vena Cava Identified After Hemodialysis Catheter Insertion: A Case Report

Introduction

Central venous catheter (CVC) insertion is the most commonly performed clinical procedure when a patient initiates hemodialysis. Despite its clinical benefits, CVC insertion has several risks of complications. Thrombosis, venous stenosis, infection, arrhythmia, pneumothorax, and bleeding are among these complications. Malposition of the tip of the CVC can also occur with an incidence of up to 7%. One of several factors that could contribute to malposition is venous anatomy variation. Persistent left superior vena cava (PLSVC) is an extremely rare venous anatomical disorder but might have a significant clinical impact.

Case Presentation

Here we report a PLSVC case that was identified in chest radiography after the insertion of a CVC catheter in a patient with end-stage renal disease (ESRD). A 40-year-old woman with a history of type 2 diabetes mellitus, hypertension, dyslipidemia, and obesity was presented in the emergency room with dyspnea for 1 week. Acute hemodialysis was required because of the ESRD and pulmonary edema. The PLSVC condition accompanied by various complications that occurred in this patient became a dilemma for the nephrologist in determining the diagnosis and proper CVC management.

Discussion

PLSVC is the most common congenital abnormality of the vena cava, even though it has a very small incidence. PLSVC occurs in about 0.1–0.5% of the total population and reaches 10% in individuals with congenital heart abnormalities. Most PLSVC presents along with normal superior vena cava and drains into the right atrium, which makes it very difficult to see the clinical signs and symptoms. Almost all PLSVC conditions are found incidentally during or after invasive procedures such as CVC insertion. CVC insertion in the PLSVC condition needs proper management to minimize the risk of complications.

Conclusion

This case shows the importance of understanding the PLSVC condition, which, although very rare, is expected to increase the awareness of the nephrologist in making the diagnosis, determining appropriate management, and preventing complications, thereby improving patient safety.

Tunnelled haemodialysis catheter insertion into the persistent left superior vena cava

Persistent left superior vena cava is an uncommon abnormality of the venous system. Most commonly, it is diagnosed incidentally during central vein catheterisation on the left side or pacemaker implantation. We present the case of a patient with persistent left superior vena cava, which was diagnosed after the attempted insertion of tunnelled haemodialysis catheter through the left internal jugular vein. The presence of the persistent left superior vena cava was confirmed by cardiac echography and angio-computed tomography scan. The 19-cm long tunnelled haemodialysis catheter was inserted into persistent left superior vena cava through the left internal jugular vein with good long-term function.

Intraoperative identification of persistent left superior vena cava with intracavitary electrocardiogram during venous port insertion: A report of eight cases

Persistent left superior vena cava is a rare congenital anomaly, occurring in 0.3% to 0.5% of general population and up to 10% in patients with congenital heart disease. This anomaly is usually discovered incidentally during central venous catheterization from left side. Since 2015, we have identified eight cases of persistent left superior vena cava out of a total of 2637 patients who had left sided venous port insertion in our department. The persistent left superior vena cavae were identified with the aid of intracavitary electrocardiogram. The characteristic finding was an initial negative P-wave (in lead II), followed by a biphasic P-wave pattern during catheter insertion. All the ports worked properly, with a total catheter dwelling time of 2586 days (range: 96-756 days, mean: 323.25 days), and no catheter-related complication was observed. However, because of the paucity of clinical evidence, we should still be prudent in the long-term use of venous ports in persistent left superior vena cava.

Catheterization in a patient with end-stage renal disease through persistent left superior vena cava: a rare case report and literature review

Background

Persistent left superior vena cava (PLSVC) is a common vena cava malformation, and drains blood into the right atrium via the dilated coronary sinus in most cases. It is usually asymptomatic and detected incidentally during invasive procedures or imaging. Whether the hemodialysis catheters can be placed in PLSVC is still controversial now (Stylianou et al. Hemodial Int 11:42-45, 2007).

Case presentation

Here we report a rare case of catheterization through PLSVC in an end-stage renal disease (ESRD) male patient whose PLSVC connected with pulmonary vein with insufficient blood flow eventually. Among the other 28 cases included in the literature review, 16 cases were non-tunneled catheter and 12 cases were cuffed, tunneled catheter and most of them could provide adequate blood flow.

Conclusion

PLSVC is a rare malformation and mostly asymptotic, we believe that PLSVC drains blood into the right atrium with enough inner diameter and blood flow can serve as an alternative site for conventional dialysis access. However, the feasibility of hemodialysis catheterization through it and measures to avoid serious complications are still needed to be discussed.

Sudden hypotension occurring after 4 days of left-sided central catheter placement

Central venous catheters (CVCs) have an important role in the management of critically ill patients. In contrast to the immediate complications after CVC insertion, the late complications were difficult to be noticed without high suspicion despite their life-threatening outcome. We report a rare but fatal delayed vascular perforation occurring after 4 days of left-sided hemodialysis catheter insertion. A 74-year-old male with septic shock was treated with continuous renal replacement therapy (CRRT) and recovered smoothly during hospitalization. Refractory hypotension occurred abruptly on the fourth hospital day. Chest X-ray and computed tomography revealed that the catheter tip perforated the innominate vein and located the mediastinum. He finally died despite the emergent radiologic intervention.

Ultrasound-guided catheterization of the left subclavian vein without recognition of persistent left superior vena cava: A case report

RATIONALE

A persistent left superior vena cava (PLSVC) is rare, but the most common thoracic venous anomaly. We report a case of PLSVC unrecognized during left subclavian vein catheterization using real-time ultrasound-guided supraclavicular approach.

PATIENT CONCERNS

A 79-year-old man with history of hypertension presented with traumatic subdural hemorrhage, subarachnoid hemorrhage, and epidural hemorrhage. Before the operation, a central venous catheter (CVC) was placed into the left subclavian vein.

DIAGNOSES

A dilated coronary sinus on echocardiogram and subsequent agitated saline test confirmed the diagnosis of PLSVC.

INTERVENTIONS

A CVC was placed into the left subclavian vein under real-time ultrasound guide, with supraclavicular approach. A postoperative chest X-ray revealed a left-sided paramediastinal course of the CVC; the CVC was removed under the impression of malposition.

OUTCOMES

The CVC functioned properly.

LESSONS

Ultrasound is used for safe and correct placement of CVC; however, the presence of PLSVC could not be detected by ultrasonography in this case. When the chest radiograph shows the central venous catheter passing along the border of the left heart and a dilated coronary sinus detected on echocardiogram, we should have suspicion of a PLSVC.

Central venous access through a persistent left superior vena cava: a case series

A persistent left superior vena cava (PLSVC) is a rare, under-recognized congenital anomaly. The PLSVC is incidentally discovered during central venous access procedures when access is obtained from the left internal jugular vein. The vast majority of PLSVCs drain into the right atrium; however, it is critical to recognize a PLSVC that drains into the left atrium as it can predispose to systemic dispersion of emboli through bypassing the lungs. Additionally, PLSVC catheterization has also been previously reported to be associated with cardiac dysrhythmias, venous stenosis, coronary sinus thrombosis, cardiac tamponade, and cardiac arrest. This case review presents three cases which illustrate the viability and safety of a PLSVC for long-term central venous access in the setting of chemotherapy and hemodialysis. Ascertaining the drainage pattern of a PLSVC with venogram, echocardiography, computed tomography is paramount prior to long-term catheterization.
