“…Mathews et al (1999) classify the anomalies of the IVC according to the anomalies of the corresponding embryonic veins, but in the anomalies of the renal segment, the complete bilateral duplication is not included. Ueda et al (1983) in an attempt to determine the incidence of the IVC anomalies observed by CT divided the double IVC anomalies only with regard to the size of the left and right IVCs. Morita et al (2007) classified pelvic venous variations in cases of congenital venous anomalies and in cases of double IVC estimated only the diameter of the left and right IVCs.…”

Duplication of the inferior vena cava: anatomy, embryology and classification proposal

et al. 2009

A case of a duplicated inferior vena cava (IVC) along with other anatomical vessel variations in a 72-year-old male cadaver is presented. The anomalous vessels involved, besides the IVC, were the left testicular vein and artery, the left suprarenal artery and a superior accessory left renal artery. Based on the gross appearance of the preaortic anastomotic trunk between the left and right IVC as well as on the underlying embryological features, a classification is proposed: incomplete bilateral duplication of the IVC and complete bilateral duplication of the IVC. The latter can be further divided into three types: major, minor and asymmetric.

“…Indeed, frequency by modern imaging techniques using CT and/or MRA are comparable to those found in the dissecting room or at surgery e.g. 0.62 % in 161 cadavers (Ongoiba et al, 2006), 0.64 % in 342 nephrectomies (Baptista-Silva et al, 1997), 1.03 % upon CT (Ueda et al, 1983). Our five cases are the first diagnosed from a pool of 7722 patients evaluated by CT and MRV in Jordan, with frequency rate 0.002 %.…”

Double Inferior Vena Cava Detected by CT Venography and Confirmed by Magnetic Resonance Venography: Embryogenesis and Literature Review

SUMMARY:A hospital based prospective study was conducted from July 2001 to July 2015 at the Department of Radiology, Jordan University Hospital, Amman, Jordan. During that period, five cases of double inferior vena cava (DIVC) were discovered among a cohort of 7722 patients (3861 men and 3861 women, 49.5±16.9 years, range 16-78 years). Cases were diagnosed by contrast-enhanced Spiral CT venography (CTV) and confirmed by turbo three-dimensional (3D) time-of-flight contrast-enhanced MR venography. The majority of patients 3166 (41 %) were referred for staging and follow-up of malignancy, postoperative complications 1777 (23 %), nonspecific abdominal pain 1467 (19 %), preoperative assessment 849 (11 %) and trauma 463 (6 %). Magnetic resonance venography showed higher sensitivity, diagnostic accuracy and noninvasive modality for assessment of IVC map. MRV is a more useful, noninvasive modality for assessment of IVC map. DIVC is a common anomaly, its incidence in our study found to be 0.064 %. The incidence, literature review, embryogenesis, and importance of this anomaly are discussed. In addition, sample figures of relevant cases are provided.

“…Abnormalities with regard to the azygos system are rare; the prevalence was reported as up to 0.1%. [1][2][3] Successful slow pathway ablation in atrioventricular nodal reentry tachycardia 4,5 and ablation of right ectopic atrial tachycardia, 6 of atrial flutter, 7 and of right-sided accessory pathway 8 in patients with an azygos venous continuation were reported. Successful PVI via a superior approach in patients with interruption of the ICV has been described.…”

A 56-year-old male patient was admitted for catheter ablation of highly symptomatic paroxysmal atrial fibrillation. During the procedure, a rare anatomic variation with an interrupted inferior caval vein (ICV) branching suprarenal into an azygos venous continuation draining into the superior caval vein was detected. Using angiography, a continuation of the ICV leading into the liver, subdividing into 5 smaller branches draining into the right atrium (RA), was displayed. Despite this challenging anatomic variation, successful pulmonary vein isolation (PVI) was performed. Case ReportA 56-year-old male patient was admitted for catheter ablation of highly symptomatic drug-refractory paroxysmal atrial fibrillation (2 to 3 episodes per week), first diagnosed 48 months before the procedure. Physical examination revealed no anomalous findings, and medical history was unremarkable except for a known 1-vessel coronary artery disease with status post bare metal stent implantation in the left anterior descending artery, normal left ventricular function, and left atrial (LA) diameter of 51 mm. No LA thrombus was detected before the procedure by transesophageal echocardiography. No additional preinterventional imaging was performed. Ablation ProcedureAfter written informed consent was obtained, the procedure was performed under conscious sedation using boli of midazolam, fentanyl, and a continuous infusion of propofol (1%). Venous accesses (8F) were achieved via the right femoral vein, the left femoral vein, and the left subclavian vein. Positioning of both deflectable diagnostic catheters (7F, Webster, Biosense Webster, Diamond Bar, Calif) in the coronary sinus from the left subclavian vein and at the Hisbundle region via the left femoral vein was unremarkable. Transseptal PunctureThe guide wire for the first transseptal sheath was introduced via the right femoral vein. The guide wire exhibited an uncommon course and did not enter the RA from inferior; angiography revealed a persistent vena azygos draining into the superior caval vein (Figure 1). An additional angiography from the ICV demonstrated suprarenal branching into an azygos vein and, as another exceptional anatomic variant, a continuation of the ICV leading to the liver vein, which subdivided into 5 branches directly entering the RA (Figure 1).Intending to minimize the periprocedural risk with regard to the challenging transseptal puncture (TP) in this unique anatomic setting, we decided to perform cryoballoon-based PVI using only a single TP. Moreover, the steerable sheath (12F, FlexCath, CryoCath, Montreal, Canada), which is used in combination with the cryoballoon system, allows complex movements within the LA and ascertains access to all PVs.The guide wire was advanced via the ICV continuation to the most medial liver vein branch (Figure 1) into the RA, providing best access to the fossa ovalis. The steerable sheath was advanced and TP was performed with pressure monitoring in standard right anterior oblique (RAO) 30°and left anterior oblique (LAO) 40°angulation...
