Project description:Persistent left superior vena cava (PLSVC) is the most frequent abnormality in the general population with the frequency of 0.1% to 0.5%. It results from the failure of the involution of the left anterior cardinal vein. Right and Left SVC can coexist together in 80% to 90% of cases. Association of PLSVC with ano rectal malformation (ARM) is very rarely reported. Hence, here is a report of a unique case of PLSVC in a female neonate with ARM.

A rare case of isolated persistent left superior vena cava diagnosed by echocardiography.

Project description:BackgroundThe persistent left superior vena cava (PLSVC) is an infrequent vascular variant. PLSVC with absent right superior vena cava, also known as isolated PLSVC, is an exceptionally rare entity. In this case we present a patient with isolated PLSVC draining to coronary sinus, diagnosed incidentally during echocardiography.Case presentationA 35-year-old man underwent a transthoracic echocardiography which showed an enormously dilated coronary sinus. Hand-agitated saline was injected via peripheral intravenous cannulas. The contrast appeared firstly in the coronary sinus before it opacified the right atrium. Since this was also visible by the right antecubital saline injection, it indicated an extremely rare case of PLSVC with the absence of right superior vena cava which was confirmed by cardiac magnetic resonance.ConclusionsThe finding of a distinctively dilated coronary sinus in echocardiography led us to further investigation using agitated saline that revealed an infrequent anomaly termed isolated PLSVC. The in-depth diagnosis of this vascular variant is crucial considering that it may lead to important clinical implications, such as difficulties with central venous access, especially in the current era of a rapid development of cardiac device therapies.

Symptomatic congenital saccular aneurysm of the inferior vena cava associated with a circumaortic left renal vein.

Project description:Congenital saccular aneurysms of the inferior vena cava (IVC) are extremely rare, with 23 cases reported so far. We present a case of a 55-year-old woman with an acute episode of back pain that mimicked aortic dissection. Computed tomography ruled out aortic dissection but demonstrated a saccular aneurysm of the infrarenal IVC and a circumaortic left renal vein. The saccular aneurysm was excised, and the postoperative anatomopathologic examination revealed that it was congenital in nature. Surprisingly, preoperative symptoms of recurrent palpitations, dyspnea, and positional abdominal discomfort resolved after resection. This is the first reported case of a symptomatic congenital saccular aneurysm of the IVC with an associated circumaortic left renal vein.

Absent right superior vena cava and persistent left superior vena cava: An incidental finding.

Project description:A patient with Marfan syndrome undergoing Bentall operation was found to have an absent right superior vena cava and persistent left superior vena cava. The dilation of coronary sinus raised the suspicion of persistent left superior vena cava. The diagnosis was confirmed by agitated saline contrast echocardiography and computed tomography of the chest.

Absent right superior vena cava.

Project description:A patient planned to be performed catheter ablation. However, three-dimensional contrast-enhanced chest computed tomography revealed isolated persistent left superior vena cava. We should know such an anatomical abnormality especially when central venous catheter or peripherally inserted central catheter is inserted from right jugular vein or right subclavian vein.

Diathermy-assisted recanalization of chronic superior vena cava obstruction, case report.

Project description:The number of cases of superior vena cava syndrome (SVCS) increased due to increased cardiac devices and central venous catheters. Management of benign SVCS is still controversial. A 51-year-old male known to have ischemic cardiomyopathy and chronic renal failure on regular hemodialysis. In the last 12 months, he had progressive shortness of breath and swelling of his upper part of the body. Examination revealed engorgement of the neck veins, facial puffiness, and pitting edema of both upper limbs. Venography showed occluded SVC. We applied a 50 Watt of energy via electrocautery pen to a Hi-Torque 0.014 Astato guidewire to cross the occluded segment retrogradely. We used 2 stents 39 mm, mounted on BIB 20/40 mm. Final angiography revealed full restoration of SVC flow. Diathermy use to cross a chronic total SVC obstruction is feasible and safe. Endovascular techniques are suitable as initial management of benign SVC syndrome.
