Duplicated inferior vena cava with coexisting multiple vascular anomalies and their clinical implications: a case report

Abstract

The paper presents the case of a 23-year-old man with multiple venous anomalies. The abnormalities were asymptomatic, and they were detected accidentally on routine abdominal ultrasound examination. The anomalies were found in the inferior vena cava, right testicular vein, left renal vein, and hepatic veins. Familiarity with different developmental variants within the inferior vena cava and other venous vessels plays a crucial role in ultrasound imaging. Vascular anomalies, although rare, should be taken into account in the differential diagnosis of focal lesions within the abdominal cavity. Also, variation in vascular anatomy may be a precipitating factor for blood flow disorders, and hence predispose patients to deep vein thrombosis and other pathological conditions. The reported case serves as a valuable addition to the knowledge of the vascular system that radiologists use in their everyday practice when performing diagnostic ultrasound examinations.

Duplicated inferior vena cava-trifurcated portal vein: a rare anatomical variation encountered during Whipple procedure

“…In the fourth week of embryogenesis, three venous systems are formed: the vitelline, the umbilical and the cardinal system. The IVC consists of four main segments: [ 2 , 5 ] the hepatic segment derives from the hepatic vein and the hepatic sinusoids; the prerenal segment originates from the right subcardinal vein; the renal segment is derived from the anastomosis of the right subcardinal anteriorly and supracardinal vein posteriorly; and the last one, the postrenal system, arises from the right supracardinal vein. Normally, the left subcardinal and supracardinal veins regress.…”

Variação De Veia Testicular Direira Em Cadáver De Adulto: Relato De Caso

“…A veia testicular apresenta grande variabilidade quanto ao número, trajeto e locais de drenagem, sendo que algumas destas variações podem levar a esterilidade masculina (NAYAK; VASUDEVA, 2020). As anomalias vasculares devem ser levadas em consideração no diagnóstico diferencial de lesões focais dentro da cavidade abdominal, além disto, a variação na Anatomia vascular pode ser um fator precipitante para distúrbios do fluxo sanguíneo e, portanto, predispor os pacientes a trombose venosa e outras condições patológicas (GOLABEK et al 2019). A proposta do nosso estudo é descrever uma variação encontrada na veia testicular direita, em cadáver formolizado de adulto.…”
