ABSTRACT

Resumen: La malposición de los catéteres venosos centrales se asocia a importantes riesgos, a menudo infraestimados. Aunque se han descrito algunos factores que pueden favorecer la malposición, generalmente su causa no llega a diagnosticarse y parece ser de origen multifactorial. Presentamos dos casos de malposición de catéteres venosos centrales motivadas por causas anatómicas inusuales, diagnosticadas en el perioperatorio. En el primer caso, se diagnostica una agenesia de vena cava superior en el transcurso de una sustitución mitral por esternotomía, que lógicamente se asocia con una malposición de la vía central insertada. La utilización de catéteres y dispositivos a través de venas yugulares y subclavias en pacientes con esta infrecuente patología implica importantes limitaciones y complicaciones potenciales graves. En el segundo caso, la existencia de un bocio no diagnosticado provoca la malposición bilateral y simultánea de dos catéteres venosos canalizados, en el contexto de una situación de emergencia, en ambas venas yugulares internas.


Abstract: Malposition of central venous catheters is associated with important and underestimated risks. Although some factors have been related with malposition, its cause is generally not diagnosed, and it seems to have multifactorial origin. We present two cases of central venous catheter malposition due to unusual anatomical causes, diagnosed in the perioperative period. In the first case, superior vena cava agenesis was diagnosed during mitral replacement by sternotomy, which was logically associated with malposition of the inserted central line. The use of catheters and devices through jugular and subclavian veins in patients with this infrequent pathology is associated with important limitations and serious potential complications. In the second case, an undiagnosed goiter causes bilateral and simultaneous malpositioning of two inserted central venous catheters, in the context of an emergency situation, in both internal jugular veins.

ABSTRACT

Persistent left superior vena cava (LSVC) with absent right SVC (RSVC) is a rare congenital anomaly. If undetected, the condition may pose difficulties in central venous catheter insertion, pacemaker electrode insertion, and cannulation during cardiopulmonary bypass. We describe a case of persistent LSVC with absent RSVC, who was diagnosed to have bicuspid aortic valve with aortic stenosis.

ABSTRACT

Objective To investigate characteristics and value of prenatal ultrasound in diagnosing persistent left and absent right superior vena cava.Methods Ultrasonic data of 8 fetuses with persistent left and absent right superior vena cava were retrospectively analyzed.Ultrasonic findings of persistent left and absent right superior vena cava and other complicated anomalies were observed,and the outcomes were followed up.Results The ultrasonic characteristics of persistent left and absent right superior vena cava included a vessel which could be seen on the left of pulmonary artery on three vessel-trachea view draining into the dilated coronary sinus,and right superior vena cava was absent.With combined spatio-temporal image correlation (STIC) and high definition flow (HDF) technique,the spatial relationship of the left superior vena cava,aorta and pulmonary artery could be observed.Dilated coronary sinus was found in all 8 fetuses,other congenital heart defects were detected in 5 fetuses,and extracardiac anomaly was found in 1 fetus.Conclusion Persistent left and absent right superior vena cava and complicated anomalies can be accurately diagnosed with prenatal ultrasound.Dilated coronary sinus is an important clue for prenatal ultrasonic diagnosis.

ABSTRACT

Persistent left superior vena cava(PLSVC) derives from abnormally persistent patency of an embryological vessel normally present during the early developmental period. The incidence of PLSVC is 0.3% in healty persons, 4.8% in patients with congenital heart anomaly. Most of the patients with PLSVC have normal right superior vena cava (RSVC), but PLSVC plus absent RSVC is very rare, especially in those without congenital heart anomalies. We experienced a case of PLSVC and absent RSVC during an insertion of internal jugular venous catheter for acute hemodialysis. A 53-year-old female was admitted due to uremia for initiation of dialytic therapy. She had long history of diabetic nephropathy but without congenital heart anomalies. We inserted a dual lumen catheter for acute hemodialysis via right internal jugular vein. On the chest x-ray film taken after the insertion of the catheter, we detected unusual course of the catheter curved to the left. PLSVC and absent RSVC was confirmed by normal saline contrast echocardiography and CT angiograpy.

ABSTRACT

Abscence of right superior vena cava(SVC) in visceroatrial situs solitus is a rare(0.07% to 0.13%) congenital cardiovascular malformation, and little is known about the type and frequency of additional heart defects and arrhythmias. We reviewed previous publications and report the case of 8 month old male infant with absent right superior vena cava and persistent left superior vena cava and large secundum atrial septal defect, mild pulmonary valvular stenosis.

ABSTRACT

A case of unilateral pulmonary vein atresia with absent right superior vena cava in 9 years-old boy is described with a discussion. Clinical findings were similar to other reports and consisted of hemoptysis, dyspnea and anemia. A chest X-rary revealed irregular vascular marking on left lung fiedld and increased interstitial marking on right upper lung field. The diagnosis could be confirmed with radionuclide perfusion study, MRI scan of heart and great vessels and angiography which demonstrated a small right pulmonary artery, pruned its peipheral branches, stasis of contrast material and nonvisualization of draining righ pulmonary veins. Pneumonectomy, patch angioplasty of diaphargm excision will be necessary.
