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

ABSTRACT: 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.

Intravascular lipoma of the inferior vena cava and left renal vein.

Project description:Intravenous lipoma of the inferior vena cava is an incidental finding on contrast-enhanced computed tomography in 0.5% of individuals. We report a case of multiple intravenous lipomas discovered during diagnosis of cholangitis in a 39-year-old woman. Imaging revealed three fatty masses that appeared connected by cordlike structures: one in the left renal vein with wide mural attachment and two in the inferior vena cava, the higher of which was mobile. We hypothesize that these originated as a single lipoma that subsequently divided into three distinct masses. Because mobile masses may cause pulmonary thromboembolism, surgery is recommended in these cases.

Prenatal Diagnosis of Aorta-Porto-Umbilical Vein Fistulas with Left-Sided Inferior Vena Cava.

Project description:Congenital arteriovenous fistulas involved with the abdominal aorta are very rare. Left-sided subrenal inferior vena cava (IVC) with normal connection to the heart is also rare and has not been reported prenatally. In this article, we described a fetus with aorta-porto-umbilical vein fistulas combined with a left-sided IVC.

Urothelial carcinoma of the renal pelvis with renal vein and inferior vena cava tumor thrombus: case series and literature review.

Project description:BackgroundUrothelial carcinoma (UC) of the renal pelvis with renal vein and inferior vena cava (IVC) tumor thrombus (TT) was extremely rare. We aimed to explore the clinical and pathological characteristics, diagnosis and treatment of renal pelvis UC with renal vein and IVC TT.MethodsFrom March 2016 to January 2019, eight patients of renal pelvis UC with renal vein and IVC TT were diagnosed and underwent operation in our hospital. Clinical features, operative details, pathological outcomes, and prognosis data were reviewed and collected.ResultsThere were five males and three females (52-84 years old). Their main symptoms were flank pain and hematuria. According to the Mayo classification, the TT was 4 level-0 (1 left and 3 right), 2 level-I (right), and 2 level-II (right). Half the patients underwent retroperitoneal laparoscopic radical nephroureterectomy with thrombectomy, and the other underwent open procedures. The mean operative time was 298.9 minutes. Pathological outcomes revealed high-grade UC, with positive lymph nodes in 6 cases. Four patients received adjuvant chemotherapy, one target therapy and one adjuvant chemotherapy combined with immunotherapy after surgery. The mean follow-up time was 11.1 months. Three patients are alive, and two of them developed recurrence and lung metastasis.ConclusionsPreoperative differentiation between renal pelvis UC and renal cell carcinoma with venous TT was very important for the management. Radical nephroureterectomy with thrombectomy might be a reasonable method for renal pelvis UC with venous TT. The prognosis of such cases was poor even if adjuvant therapy was scheduled.

Adrenocortical Carcinoma with a Renal Vein Thrombus Extending to the Inferior Vena Cava Successfully Resected with the Left Kidney and Distal Pancreatectomy: A Case Report.

Project description:IntroductionAdrenocortical carcinoma (ACC) is an extremely rare and aggressive tumor, and its clinical characteristics are poorly defined because of its rarity.Case presentationWe report a 64-year-old man who presented with upper abdominal pain and weight loss. Computed tomography revealed a 15 cm left adrenal tumor compressing the pancreas ventrally and a tumor thrombus in the inferior vena cava (IVC) originating from the left renal vein. Positron emission tomography-computed tomography revealed 18F-fluorodeoxyglucose uptake only in the tumor and tumor thrombus, and radical surgery was planned. Intraoperatively, the tumor was visible on the posterior stomach wall, and the tumor adhered to the pancreas and left kidney. We excised the tumor with part of the pancreas and the left kidney and excised the thrombus from the IVC after clamping. The final diagnosis was ACC, tumor-node-metastasis grade T3N1M0, stage III. The patient received chemotherapy and radiotherapy postoperatively; however, two liver metastases appeared 6 months after surgery. Chemotherapy was continued, and no exacerbation of the liver metastases was observed. Posterior segment resection of the liver was performed 16 months after the initial surgery.ConclusionThis report of a rare case of ACC involving the pancreas with tumor thrombus extension to the IVC stresses that this combination of conditions does not preclude radical surgery. However, more data are needed regarding chemotherapy and radiotherapy, as well as relapse treatment, and further research on ACC is essential for a favorable prognosis.

Inferior vena cava filter thrombosis.

Project description:Patients with inferior vena cava (IVC) filters - particularly permanent filters - are at increased risk for recurrent deep venous thrombosis (DVT). Judicious use of IVC filters, as well as the prompt retrieval of temporary IVC filters, substantially reduces the risk of IVC thrombosis.

A Predictive Model for Tumor Invasion of the Inferior Vena Cava Wall Using Multimodal Imaging in Patients with Renal Cell Carcinoma and Inferior Vena Cava Tumor Thrombus.

Project description:Purpose:Developed a preoperative prediction model based on multimodality imaging to evaluate the probability of inferior vena cava (IVC) vascular wall invasion due to tumor infiltration. Materials and Methods:We retrospectively analyzed the clinical data of 110 patients with renal cell carcinoma (RCC) with level I-IV tumor thrombus who underwent radical nephrectomy and IVC thrombectomy between January 2014 and April 2019. The patients were categorized into two groups: 86 patients were used to establish the imaging model, and the data validation was conducted in 24 patients. We measured the imaging parameters and used logistic regression to evaluate the uni- and multivariable associations of the clinical and radiographic features of IVC resection and established an image prediction model to assess the probability of IVC vascular wall invasion. Results:In all of the patients, 46.5% (40/86) had IVC vascular wall invasion. The residual IVC blood flow (OR 0.170 [0.047-0.611]; P = 0.007), maximum coronal IVC diameter in mm (OR 1.203 [1.065-1.360]; P = 0.003), and presence of bland thrombus (OR 3.216 [0.870-11.887]; P = 0.080) were independent risk factors of IVC vascular wall invasion. We predicted vascular wall invasion if the probability was >42% as calculated by: {Ln?[Pre/(1 - pre)] = 0.185 × maximum?cornal?IVC?diameter + 1.168 × bland?thrombus-1.770 × residual?IVC?blood?flow-5.857}. To predict IVC vascular wall invasion, a rate of 76/86 (88.4%) was consistent with the actual treatment, and in the validation patients, 21/26 (80.8%) was consistent with the actual treatment. Conclusions:Our model of multimodal imaging associated with IVC vascular wall invasion may be used for preoperative evaluation and prediction of the probability of partial or segmental IVC resection.
