We report a case of massive pulmonary embolus demonstrated on CT in an adult male presenting with dyspnea, with no known risk factors for embolism. Abdominal CT on further investigation showed a renal tumor invading the left renal vein and the inferior vena cava as the cause of the pulmonary embolus. In a patient presenting with pulmonary artery embolism without venous thrombosis, the differential diagnosis should include an occult tumor as the cause of the embolus.

Preterm Baby

A borderline preterm baby is born with an emergency caesarean section. The baby is found to have an unprovoked occlusive thrombosis in the left renal vein and inferior vena cava. There are no obvious risk factors for thrombosis. The baby is commenced on un-fractionated heparin (UFH) followed by a prolonged course of low molecular weight heparin (LMWH) based on the guidelines adopted from adult evidence. You wonder if this is reasonable to treat neonates as per adult guidelines given the great differences between adult and neonatal clotting parameters.

ABSTRACT OBJECTIVE: The normal anatomic course of the left renal vein (LRV) from the kidney to inferior vena cava (IVC) is usually preaortic. It is called retroaortic left renal vein (RLRV) when located between the aorta and vertebra; the circumaortic left renal vein (CLRV) has both a preaortic and retroaortic course. In this study, we aimed to find the incidence and characteristics of LRV abnormalities in routine abdominal CT and MR examinations conducted in our clinic. MATERIALS AND METHODS: A total of 2189 abdominal CT and MR examinations, performed between April 2007 and June 2009, were reviewed retrospectively for retroaortic and circumaortic LRV abnormalities. RESULTS: LRV abnormalities were detected in 50 (2.3%) examinations. Forty-four of these (2%) were RLRV and 6 (0.3%) were circumaortic LRV abnormalities. CONCLUSIONS: Preoperative knowledge of LRV abnormalities facilitates the safe performance of surgery and reveals the clinical symptoms. It is easy to see LRV and its drainage way on routine CT and MR imagings

Iliac Vein Thrombosis

Among thrombophilic risk factors for deep venous thrombosis (DVT), agenesis of the inferior vena cava (AIVC) is very rare, but it must be considered in specific settings. Here, we present the case of an 18-year-old woman who was admitted to the Emergency Department with swelling and pain of her left leg. Clinical examination and ultrasonography detected extensive proximal DVT of the left leg. After attempted mechanical thrombectomy failed, an abdominal CT scan was obtained, which demonstrated bilateral thrombosis of the iliac-femoral axis in the context of congenital AIVC.

A rare and unpredictable complication of firearm and missile injuries is projectile embolism. With only a few cases described in the literature, bullet embolism may become a diagnostic challenge for emergency physicians and military surgeons. Bullet embolization is a rare phenomenon, but the complications can be devastating. Case presentation. A 34‑year‑old man sustained a severe complex abdominoskeletal mine‑blast injury with damage to the hollow organs (duodenum and transverse colon), inferior vena cava and both low extremities. The internal hemorrhage was stopped by phleborrhaphy. The wounds of the duodenum and large intestine were sutured, and gunshot fractures of both anticnemions were stabilized by extrafocal osteosynthesis. The whole‑body CT showed that there was a projectile embolus into the branch of the right mid‑lobe pulmonary artery. No clinical manifestations of pulmonary artery embolism were observed in the patient. After surgery, he developed multiple necrosis and transverse colon perforations that resulted in fecal peritonitis. The suture line leakage that caused the formation of a duodenal fistula and postoperative wound infection were also detected. The complications were managed by multiple reoperations. The attempts of endovascular bullet extraction weren’t undertaken due to severe concomitant injuries, complications and asymptomatic clinical course of pulmonary artery projectile embolism. Open surgery retrieval of the embolus was successfully performed on the 80th day after injury. The patient was discharged from the hospital in good condition on the 168th day after the missile wound. Conclusions. Patients with missile wounds and no exit gunshot perforation should be examined using the whole‑body CT for determining possible migration of a projectile with the blood flow. Patients with asymptomatic pulmonary artery embolism should be managed nonoperatively. In case of symptomatic pulmonary artery projectile embolism, it is reasonable to consider the possibility of open thoracic surgery.

Objective: To determine the prevalence of inferior vena cava (IVC) anomalies in Thai patients who underwent contrast-enhanced computed tomography (CT) of the abdomen. Materials and Methods: Two radiologists retrospectively and independently reviewed the contrast-enhanced abdominal CT examinations in 1,429 Thai patients between August 1, 2018 and January 25, 2019 who met the inclusion criteria. Patients were included, if (a) their CT showed well visualized IVC, renal veins, and right ureter that were not obliterated by tumor, cyst, fluid collection, or intraperitoneal free fluid, (b) they had not undergone previous abdominal surgery that altered anatomical configuration of the IVC, renal veins, and right ureter. The presence of all IVC anomalies were recorded. Results: Among the 1,429 studied patients, 678 were male (47.4%) and 751 were female (52.6%). The prevalence of IVC anomalies was 3.5%. Five types of IVC anomalies were presented. The most common was circumaortic left renal vein in 24 patients or 48.0% of all IVC anomalies and 1.7% of the study population, followed by retroaortic left renal vein in 15 patients or 30.0 % of all IVC anomalies and 1.0% of the study population. Other IVC anomalies included double IVC, left IVC, and retrocaval ureter at 0.5%, 0.2%, and 0.1% of the study population, respectively. Conclusion: The prevalence of IVC anomalies in the present study differed from the previous studies conducted in other countries, which may be attributable to differences in race and ethnicity. Awareness of these anomalies is essential when evaluating routine CT examinations in asymptomatic patients. Their presence should be carefully noted in radiology reports to avoid anomaly-related complications.
