Project description:BackgroundThis article describes a rare case of inferior vena cava (IVC) filter perforation into the duodenum in a patient presenting with abdominal pain.Case reportA 55 year old woman presented with abdominal pain four years after an IVC filter placement. Workup demonstrated an IVC filter strut perforating the duodenum. The filter was removed via laparotomy, the duodenum was closed primarily, and the IVC was repaired. The patient was discharged home on post-operative day five and is doing well.ConclusionsMost extraluminal perforations of IVC filter struts are asymptomatic. Rare filter associated duodenal perforations may present with non-specific abdominal symptoms. If no other diagnosis can be attributed to the patient's presentation, direct removal of the filter and repair of the duodenum are indicated.

Project description:Background: Previous observational studies suggest that inferior vena cava filter placement in pulmonary embolism patients complicated with congestive heart failure, mechanical ventilation, and shock may have a mortality benefit. We sought to analyze the survival benefits of inferior vena cava filter in pulmonary embolism patients complicated with acute myocardial infarction, acute respiratory failure, shock, or requiring treatment with thrombolytics. Methods: This retrospective observational study used hospital discharge data from the National Inpatient Sample Data (NIS). ICD-9-CM coding was used to identify complicated pulmonary embolism patients (N = 254,465) in NIS from 2002 to 2014, including the subgroups of acute myocardial infarction, acute respiratory failure, shock, and thrombolytics. Inferior vena cava filter recipients were 1:1 propensity score-matched on age, sex, race, deep vein thrombosis, Elixhauser comorbidities, and other pulmonary embolism comorbidities (45 covariates) to non-inferior vena cava filter recipients in complicated pulmonary embolism patients and separately in each subgroup. Clinical outcomes were compared between the inferior vena cava filter group and the non-inferior vena cava filter group. Results: Mortality rate in complicated pulmonary embolism patients with inferior vena cava filter placement was lower (20.9% vs. 33%; NNT = 8.28, 95% confidence interval (CI) 7.91-8.69, E-value = 2.53) and in the subgroups; acute myocardial infarction (17.9% vs. 30.1%; NNT = 8.19, 95% CI 7.52-8.92, E-value = 2.76), acute respiratory failure (19.5% vs. 29.7%; NNT = 9.76, 95% CI 8.67-11.16, E-value = 2.38), shock (30.7% vs. 47.1%; NNT = 6.08, 95% CI 5.73-6.47, E-value = 2.43), and with the use of thrombolytics (7% vs. 12.9 %; NNT 17.1, 95% CI 14.88-20.12, E-value = 3.01) (p < 0.001 for all). Conclusion: Inferior vena cava filter placement in pulmonary embolism complicated with acute myocardial infarction, acute respiratory failure, shock, or requiring thrombolytic therapy was associated with reduced mortality.

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.

Project description:As part of a program targeted at developing a resorbable valved tube for replacement of the right ventricular outflow tract, we compared three biopolymers (polyurethane [PU], polyhydroxyalkanoate (the poly(3-hydroxybutyrate-co-3-hydroxyvalerate-co-4-hydroxyvalerate) [PHBVV]), and polydioxanone [PDO]) and two biofunctionalization techniques (using adipose-derived stem cells [ADSCs] or the arginine-glycine-aspartate [RGD] peptide) in a rat model of partial inferior vena cava (IVC) replacement. Fifty-three Wistar rats first underwent partial replacement of the IVC with an acellular electrospun PDO, PU, or PHBVV patch, and 31 nude rats subsequently underwent the same procedure using a PDO patch biofunctionalized either by ADSC or RGD. Results were assessed both in vitro (proliferation and survival of ADSC seeded onto the different materials) and in vivo by magnetic resonance imaging (MRI), histology, immunohistochemistry [against markers of vascular cells (von Willebrand factor [vWF], smooth muscle actin [SMA]), and macrophages ([ED1 and ED2] immunostaining)], and enzyme-linked immunosorbent assay (ELISA; for the expression of various cytokines and inducible NO synthase). PDO showed the best in vitro properties. Six weeks after implantation, MRI did not detect significant luminal changes in any group. All biopolymers were evenly lined by vWF-positive cells, but only PDO and PHBVV showed a continuous layer of SMA-positive cells at 3 months. PU patches resulted in a marked granulomatous inflammatory reaction. The ADSC and RGD biofunctionalization yielded similar outcomes. These data confirm the good biocompatibility of PDO and support the concept that appropriately peptide-functionalized polymers may be successfully substituted for cell-loaded materials.

Project description:Introduction Kidney and liver cysts in autosomal dominant polycystic kidney disease (ADPKD) can compress the inferior vena cava (IVC), but IVC compression prevalence and its risk factors are unknown. Methods Patients who have ADPKD (n = 216) with abdominal magnetic resonance imaging (MRI) studies and age-/sex-matched controls (n = 216) were evaluated for IVC compression as well as azygous vein diameter (a marker of collateral blood flow) and IVC aspect ratio (left-to-right dimension divided by anterior-to-posterior dimension with a value of 1 corresponding to a circular (high pressure) IVC caudal to compression. Results Severe IVC compression (?70%) was observed in 33 (15%) ADPKD subjects and mild compression (?50% to <70%) was observed in 33 (15%) subjects; whereas controls had no IVC compression (P < 0.001). Severe IVC compression was associated with larger azygous vein (4.0 ± 1.3 mm versus 2.3 ± 0.8 mm without IVC compression; P < 0.001) and a more circular IVC cross-section upstream (mean IVC aspect ratio: 1.16 ± 0.27 vs. 1.69 ± 0.67, P < 0.001), suggesting higher pressure upstream from the compression. IVC compression was associated with older age, lower estimated glomerular filtration rate (eGFR), greater height-adjusted total kidney volumes, greater height-adjusted liver volume (ht-LV), and greater liver and renal cyst fractions (P < 0.001). No subject younger than 30 years had IVC compression, but ADPKD subjects ?40 years old had 12-fold higher risk of IVC compression (95% confidence interval [CI]: 4.2–42.4), with highest predicted probability for Mayo Clinic classes 1D (59%; 95% CI: 39%–76%) and 1E (74%; 95% CI: 49%–90%) after adjustment (P < 0.001). Women with ht-LV ? 2000 ml/m had 83% (95% CI: 59%–95%) prevalence of IVC compression. Complications of IVC compression included deep vein thrombosis (DVT) and symptomatic hypotension. Conclusions IVC compression is common in ADPKD patients >40 years old, with Mayo Clinic class 1D/E, and in females with ht-LV > 2000 ml/m. Graphical abstract

Project description:This case describes a 57-year-old morbidly obese woman with complications of a permanent Bard inferior vena cava (IVC) filter (BD Bard, Covington, Ga) placed in 2005. She complained of recurrent abdominal pain for 6 years associated with constipation, nausea, and bloating. Computed tomography venography showed an IVC filter with malposition, strut fracture, and extrusion, and a fractured strut protruded outside of the vena cava, adjacent to the distal right common iliac artery. The da Vinci Xi Surgical System (Intuitive Surgical, Sunnyvale, Calif) was used to remove the IVC filter and its displaced fractured strut. The operation time was 189 minutes, with an estimated blood loss of 200 mL. She was discharged home on postoperative day 2 with no complications. She had complete resolution of abdominal pain at her follow-up appointment.

Project description:Emphysematous pyelonephritis (EPN) is a progressive necrotizing infection of the renal parenchyma, collecting system and perinephric tissue. A 36-year female with uncontrolled diabetes, presented with left emphysematous pyelonephritis, with air in the infra-hepatic inferior vena cava (IVC). She was hydrated, treated with intravenous antibiotics, insulin. Percutaneous nephrostomy with Double J stenting was done in modified supine position. Patient was discharged with nephrostomy. Two weeks later, flexible ureterorenoscopy was done and obstructing papillary necrosis removed. Pneumo-vena cava due to emphysematous pyelonephritis is quite rare and careful evaluation is required. Prompt intervention is life saving and obviates the need for nephrectomy.

Project description:Tumor invasion into the inferior vena cava (IVC) and hepatic vein (HV) is challenging in cancer surgery with curative intent. Appropriate techniques for venous reconstruction are essential. We have described in detail a novel technique of fashioning an interposition tube graft using the falciform ligament to reconstruct the IVC and HV. The falciform ligament maintains all the benefits of an autologous tissue graft, with the added advantage of its flexibility in customizing graft dimensions. Its use in IVC and HV reconstruction has rarely been reported. The short-term outcomes with this tube graft are promising.

Project description:BackgroundInferior vena cava thrombosis is a rare blunt abdominal trauma complication often associated with severe liver injury. We present two cases of inferior vena cava thrombosis due to mild liver injuries.Case presentationCase 1 was a 25-year-old woman taking oral contraceptives for dysmenorrhea who was injured in a motorcycle accident. Contrast-enhanced computed tomography revealed hepatic contusion of the sixth segment. At 1 week after the accident, inferior vena cava thrombosis was detected. Case 2 was a 58-year-old man injured in a motorcycle accident. Contrast-enhanced computed tomography showed traumatic subarachnoid hemorrhage, right hemothorax, and liver injury with hepatic contusion of the sixth segment. At 1 week after the accident, inferior vena cava thrombosis was observed.ConclusionInferior vena cava thrombosis can occur following liver injury, regardless of damage severity. When there are thrombogenic factors and damage near the inferior vena cava, follow-up examinations should be carried out.

Project description:PurposeTo compare filter tilt and filter jumping during Option inferior vena cava (IVC) filter deployment with 3 different wires techniques using a 3-dimensional (3D) printing vena cava phantom.Materials and methodsAn IVC 3D printed vena cava phantom was made from a healthy young male's computed tomographic data. Option IVC filters were deployed with 3 different wires: i) original push wire, ii) hydrophilic stiff wire, and iii) bent stiff wire. Right internal jugular and right femoral access were used 5 times with each wire. Filter tilt angle, tilt ratio, jumping, and tip abutment to the IVC wall were analyzed.ResultsThe transfemoral approach with original push wire had significantly higher tilt angle than did the transjugular approach (6.1˚ ± 1.9 vs. 3.5˚ ± 1.3, p = 0.04). Mean tilt ratio was significantly lower with the bent wire with transfemoral access (0.49 ± 0.13 vs. 0.78 ± 0.18 [original push-wire] and 0.67 ± 0.08 [stiff wire], p = 0.019). The ratio was lower also with original push wire with transjugular access (0.34 ± 0.19 vs. 0.57 ±0.11 [stiff wire] and 0.58 ±0.17 [bent wire], p = 0.045). Filter jumping occurred more often with the transjugular approach with original push wire than with stiff or bent-wire delivery. Filter tip abutment to the IVC wall occurred only with the transfemoral approach.ConclusionsBent wire with transfemoral access and original push wire with transjugular access had lower filter tilt ratio at Option IVC filter deployment. However, filter jumping was common using the original push wire with transjugular access.
