POLIESPLENIA E ANOMALIA DO SISTEMA PORTAL HEPÁTICO ASSOCIADAS À AUSÊNCIA DE VEIA CAVA INFERIOR EM CRIANÇA: RELATO DE CASO

Agenesis of inferior vena cava (IVC)is a rare cardiovascular malformation that occurs between the sixth and tenth week of embryogenesis. It may be associated with cardiac and abdominal malformations, besidescomplications such as deep vein thrombosis (DVT). The present study reports the case of a patient randomly diagnosed with total IVC agenesis associated with malformation of the portohepatic system and polysplenia. Female patient, 9 years old, being monitored for hemorrhagic dengue, withcomputed tomographyand abdominal ultrasound revealing anomaly of the development of the hepatic portal system associated with the absence of inferior vena cava with continuation inretrocrural azygos vein, in addition to multiple accessory spleens. When the anastomoses of the IVCprimitive veins are not formed properly, partial or total agenesis of this vessel may occur. Consequently, the blood is diverted to the retrocrural azygos. Identification of these malformations is important for the patients receive proper guidance about DVT prevention, in additionto monitoring them for diagnosis of other possible malformations.

Background: Inferior vena cava (IVC) filters are commonly used in China to prevent pulmonary embolisms in patients with deep vein thrombosis. However, IVC filter removal is complicated when the filter has penetrated the IVC wall and endovascular techniques usually fail. The purpose of this study was to evaluate the effectiveness and safety of retroperitoneal laparoscopic-assisted retrieval of wall-penetrating IVC filters after endovascular techniques have failed. Patients and Methods: We retrospectively evaluated a series of 8 patients who underwent retroperitoneal laparoscopic-assisted retrieval of a wall-penetrating IVC filter between December 2017 and November 2019. All patients had experienced at least 1 failure with endovascular retrieval before the study. The filters were slanted and the proximal retrieval hooks penetrated the posterior lateral IVC wall in all patients on computed tomography. Demographic information, operation parameters, and complications were recorded and analyzed. All patients were followed up for at least 12 months. Results: The procedure was successful in all patients. The median surgery time was 53.6 ± 12.7 min and the average blood loss was 45.0 ± 13.5 ml. No serious complication occurred during the patients’ hospitalization, which was an average of 6.4 days. The median follow-up time was 15.1 months, and no patient had deep vein thrombosis recurrence. Conclusions: Retroperitoneal laparoscopic-assisted retrieval is a feasible and effective technique, particularly when proximal retrieval hooks penetrate the posterior lateral wall of the IVC after endovascular techniques have failed. To some extent, the development of this technique at our institution has increased the success rate of filter removal and improved patient satisfaction.
