Filtro de vena cava inferior ante diagnóstico de trombosis venosa profunda en gestante en trabajo de parto. A propósito de un caso clínico / Inferior vena cava filter before diagnosis of deep venous thrombosis in a pregnant woman in labor: A case report

Introducción: El embarazo representa un estado procoagulante que aumenta el riesgo de fenómenos trombóticos en la mujer. Al igual que en la población no gestante, deberemos diagnosticar y tratar lo más precozmente posible dichos eventos para evitar la migración del trombo a otras localizaciones. La anticoagulación constituye la medida terapéutica de primera línea. Sin embargo, ciertas situaciones de aumento de sangrado como el trabajo de parto pueden suponer una contraindicación para iniciar dicha anticoagulación. En el siguiente artículo se desarrolla un caso clínico en el que el diagnóstico de trombosis venosa profunda tuvo lugar al inicio del trabajo de parto. Principales síntomas y/o hallazgos clínicos: Aumento de diámetro de miembro inferior izquierdo, con enrojecimiento del mismo y aumento de temperatura local. La paciente describía dolor a nivel de dicha extremidad desde hacía 15 días. No presentaba disnea y la saturación de oxígeno era del 100%. Diagnósticos principales: Trombosis venosa profunda, trabajo de parto. Intervenciones terapéuticas: La contraindicación de anticoagulación y la necesidad de un tratamiento inmediato plantearon el filtro de vena cava inferior como la opción más razonable. Resultados: Tras la colocación del filtro, el parto cursó sin incidencias; no migró el émbolo y el filtro se retiró a los 29 días del parto sin complicaciones. Conclusión: Pese a nuestra escasa experiencia clínica en el manejo de estos casos, podemos afirmar que el filtro de vena cava inferior representa una opción razonable y segura en los casos de trombosis de miembros inferiores en mujeres en trabajo de parto.(AU)

Introduction: Pregnancy represents a procoagulant state that increases women's risk of thrombotic phenomena. As in the non-pregnant population, we must diagnose and treat these events as early as possible to avoid the migration of the thrombus to other locations. Anticoagulation is the first-line therapeutic measure. However, certain situations of increased bleeding such as labor may be a contraindication to initiate such anticoagulation. The following article develops a clinical case in which the deep vein thrombosis diagnosis occurred at the onset of labor. Main symptoms and/or clinical findings: Increase in diameter of the left lower limb, with redness of the same and increase in local temperature. The patient described pain at the level of this limb for 15 days. He had no dyspnea and oxygen saturation was 100%. Main diagnoses: Deep vein thrombosis, labor. Therapeutic interventions: The contraindication of anticoagulation and the need for immediate treatment raised the inferior vena cava filter as the most reasonable option. Results: After the placement of the filter, the delivery proceeded without incident. The plunger did not migrate and the filter was removed 29 days after delivery without complications. Conclusion: Despite our limited clinical experience in the management of these cases, we can affirm that the inferior vena cava filter represents a reasonable and safe option in cases of thrombosis of the lower limbs in women in labor.(AU)

CT findings of inferior vena cava trauma according to the level of injury: a retrospective analysis of 19 cases in a single trauma centre.

AIM: To analyse the clinicoradiological characteristics of traumatic inferior vena cava (IVC) injury level on preoperative computed tomography (CT). MATERIALS AND METHODS: This retrospective study evaluated patients from a single trauma centre treated for traumatic IVC injury between January 2014 and January 2021. Data on demographics, mechanism of injury, Injury Severity Score, radiological findings on CT and angiography, IVC injury level in surgical findings, complications, and clinical outcomes were collected. RESULTS: During the 8-year study period, 36 patients presented with traumatic IVC injury: 19 underwent preoperative CT with 17 (89%) blunt and two (11%) penetrating injuries. The most common primary CT sign was contour abnormality (53%, n=10), followed by intraluminal flap and active extravasation (21%, n=4). Among the secondary signs, hepatic laceration (53%, n=10) and retroperitoneal haemorrhage (53%, n=10) were the most common. Frequencies of primary and secondary signs were higher in the infrarenal and suprarenal than in the retrohepatic vena cava injuries. Diagnostic capability of preoperative CT for IVC injury differed according to the IVC level. The detection rate was the highest for an infrarenal vena cava injury at 100% (n=4), followed by that for a suprarenal, suprahepatic, and retrohepatic vena cava injuries at 75% (n=3), 43% (n=3), and 25% (n=1), respectively. CONCLUSION: CT findings of traumatic IVC injuries may vary depending on the mechanism and anatomical site of injury. Familiarity with IVC injury imaging features may help in diagnosis and surgical treatment planning.

Laparoscopic resection of a paraganglioma behind the retrohepatic segment of the inferior vena cava: a case report and literature review.

Background: Due to the location of paragangliomas (PGLs) behind the retrohepatic segment of inferior vena cava (IVC), it is difficult to expose and resect the tumor. Case presentation: A tumor measuring 50×45×62cm behind the retrohepatic portion of IVC was found in a 51-year-old female with hypertention and diabetes mellitus. Although the test for catecholamines revealed no signs of disease, the enhanced computed tomography (CT) scan, somatostatin receptor imaging and iodine-131-labeled metaiiodo-benzylguanidine (131I-MIBG) imaging revealed that the tumor was PGL. A three-dimensional printing was performed to visualize the tumor. The laparoscpic surgery for the PGL behind the retrohepatic segment of IVC was performed and the tumor was resected completely without causing any tissues injury. The pathologic diagnosis was PGL and the patient was able to recover well. Conclusions: This case demonstrates that laparoscopic surgery may be helpful in tumor accessibility, and could be used in the appropriate cases to remove PGLs that are located behind the retrohepatic segment of the IVC.

Contemporary Management and Outcomes of Injuries to the Inferior Vena Cava: A Prospective Multicenter Trial From PROspective Observational Vascular Injury Treatment.

INTRODUCTION: Injuries to the inferior vena cava (IVC), while uncommon, have a high mortality despite modern advances. The goal of this study is to describe the diagnosis and management in the largest available prospective data set of vascular injuries across anatomic levels of IVC injury. METHODS: The American Association for the Surgery of Trauma PROspective Observational Vascular Injury Treatment (PROOVIT) registry was queried from November 2013 to January 2019. Demographics, diagnostic modalities, injury patterns, and management strategies were recorded and analyzed. Comparisons between anatomic levels were made using non-parametric Wilcoxon rank-sum statistics. RESULTS: 140 patients from 19 institutions were identified; median age was 30 years old (IQR 23-41), 75% were male, and 62% had penetrating mechanism. The suprarenal IVC group was associated with blunt mechanism (53% vs 32%, P = .02), had lower admission systolic blood pressure, pH, Glasgow Coma Scale (GCS), and higher ISS and thorax and abdomen AIS than the infrarenal injury group. Injuries were managed with open repair (70%) and ligation (30% overall; infrarenal 37% vs suprarenal 13%, P = .01). Endovascular therapy was used in 2% of cases. Overall mortality was 42% (infrarenal 33% vs suprarenal 66%, P<.001). Among survivors, there was no difference in first 24-hour PRBC transfusion requirement, or hospital or ICU length of stay. CONCLUSIONS: Current PROOVIT registry data demonstrate continued use of ligation extending to the suprarenal IVC, limited adoption of endovascular management, and no dramatic increase in overall survival compared to previously published studies. Survival is likely related to IVC injury location and total injury burden.

Endovascular Balloon Occlusion of the Inferior Vena Cava in Trauma: A Single-Center Case Series.

Injury to the inferior vena cava (IVC) can produce bleeding that is difficult to control. Endovascular balloon occlusion provides rapid vascular control without extensive dissection and may be useful in large venous injuries, especially in the juxtarenal IVC. We describe the procedural steps, technical considerations, and clinical scenarios for using the Bridge occlusion balloon (Philips) in IVC trauma. We present a single-center case series of 5 patients in which endovascular balloon occlusion of the IVC was used for hemorrhage control. All 5 patients were men (median age 35, range 22 to 42 years). They all sustained penetrating injuries-4 gunshot wounds and 1 stab wound. Median presenting Shock Index was 0.7 (range 0.5 to 1.5). Median initial lactate was 5.4 mmol/L (range 4.6 to 6.9 mmol/L). There were 2 suprarenal IVC injuries, 2 juxtarenal injuries, and 3 infrarenal injuries. Four patients underwent primary repair of their injury, and one underwent IVC ligation. Four patients had intraoperative Resuscitative Endovascular Balloon Occlusion of the Aorta for inflow control and afterload support. The median number of total blood products transfused during the initial operation was 37 units (range 16 to 77 units). Four patients underwent damage control operations, and one patient had a single definitive operation. Four of the 5 patients (80%) survived to discharge with the lone mortality being due to other injuries. Endovascular balloon occlusion serves as a valuable adjunct in the management of IVC injury and demonstrates the potential of hybrid open-endovascular operative techniques in abdominal vascular trauma.

Inferior Vena Cava Ligation and Pancreaticoduodenectomy in a Patient With Penetrating Abdominal Trauma.

INTRODUCTION: Injury to the inferior vena cava (IVC) is often fatal. Pancreaticoduodenectomy for trauma is also rare. This case describes a patient who underwent both procedures. CASE PRESENTATION: A 30-year-old male presented status post gunshot to the abdomen. He was taken to the operating room and found to have 6 cm defect in the IVC, which was ligated. Despite resuscitation, the patient required emergent return to the OR where bleeding from the pancreaticoduodenal artery was noted in addition to injuries in the stomach, duodenum, and pancreas. He subsequently underwent a pancreaticoduodenectomy. He was discharged after a month-long hospital stay. CONCLUSIONS: This case demonstrates that IVC ligation is a form of damage of control surgery. Pancreaticoduodenectomy is rarely performed during the index operation for trauma patients. Patient with injuries to the pancreaticoduodenal complex can be life-threatening if not rapidly controlled. This patient is a rare example of someone who survived two morbid trauma surgery interventions.

Management of Renal Artery-Inferior Vena Cava Fistula Following Nephrectomy for Penetrating Trauma.

Background: Renal artery to inferior vena cava fistula is a rare event postnephrectomy. We report a case of an adult male in whom a renal artery to inferior vena cava fistula was detected on non-invasive studies following nephrectomy for penetrating trauma. Case Report: A fistula between the right renal artery and inferior vena cava was confirmed with diagnostic angiography. The fistula was successfully embolized using microcoils. Discussion: This case highlights the importance of exploring retroperitoneal hematomas secondary to penetrating trauma.

Lessons Learned From Treating 114 Inferior Vena Cava Injuries at a Limited Resources Environment - A Single Center Experience.

BACKGROUND: The inferior vena cava is the most frequently injured vascular structure in penetrating abdominal trauma. We aimed to review inferior vena cava injury cases treated at a limited resources facility and to discuss the surgical management for such injures. METHODS: This was a retrospective study of patients with inferior vena cava injuries who were treated at a single center between January 2011 and January 2020. Data pertaining to the following were assessed: demographic parameters, hypovolemic shock at admission, the distance that the patient had to be transported to reach the hospital, affected anatomical segment, treatment, concomitant injuries, complications, and mortality. Non-parametric data were analyzed using Fisher's exact, Chi-square, Mann-Whitney, or Kruskal-Wallis test, as applicable. The Student's t-test was used to assess parametric data. Moreover, multiple logistic regression analyses (including data of possible death-related variables) were performed. Statistical significance was set at P <0.05. RESULTS: Among 114 patients with inferior vena cava injuries, 90.4% were male, and the majority were aged 20-29 years. Penetrating injuries accounted for 98.2% of the injuries, and the infrarenal segment was affected in 52.7% of the patients. Suturing was perfomed in 69.5% and cava ligation in 29.5% of the patients, and 1 patient with retrohepatic vena cava injury was managed non-operatively. The overall mortality was 52.6% with no case of compartment syndrome in the limbs. A total of 7.9% of the patients died during surgery. CONCLUSION: The inferior vena cava is often injured by penetrating mechanisms, and the most frequently affected segment was the infrarenal segment. A higher probability of death was not associated with injury to a specific anatomical segment. Additionally, cava ligation was not related to an increased probability of compartment syndrome in the leg; therefore, prophylactic fasciotomy was not supported.

Our clinical experiences of vascular injuries due to lumbar disc surgeries.

OBJECTIVES: We aimed to evaluate emergency vascular complications of the lumbar disc reconstructive surgery in this study. METHOD: Between March 2006 and February 2020, nine patients (six males and three females; mean age: 53.4 ± 9.6 years; range: 38-64 years) who underwent emergent vascular intervention during lumbar spinal disc reconstructive surgery in our clinic were included in this retrospective study. RESULT: The left common iliac artery injury, the left common iliac artery and left common iliac vein injuries, bilateral common iliac artery and abdominal aortic injuries, and vena cava inferior injury with left common iliac vein and right common iliac vein injuries were detected in two, three, two, and two patients, respectively. In addition, 16 mm Dacron tube graft interposition and graft patch plasty were performed in one and two patients who had an abdominal aortic injury, respectively. Also, 8 mm polytetrafluoroethylene straight graft interposition was performed in two patients with left common iliac artery injury, and lateral wall repair was performed in other patients. Graft patch plasty and 8 mm polytetrafluoroethylene graft interposition were performed in one patient with vena cava inferior injury and left common iliac vein injury, respectively. Also, lateral wall repair was performed in other patients with venous injuries. Deep venous thrombosis had developed in three patients, and one patient of these had a pulmonary embolism. CONCLUSION: The incidence of vascular injury after the lumbar disc surgery is relatively low; however, the emergency vascular operation should be performed as soon as possible.

Inferior vena caval aneurysm diagnosed in context of trauma.

Inferior vena cava (IVC) aneurysms remain rare vascular entities that carry significant morbidity and potential mortality. Given the paucity of literature on this clinical entity, there is no consensus regarding management guidelines, and it is important to continue to add to the current literature body. In this report, we describe the case of a 64-year-old male diagnosed with a type III IVC aneurysm. Here, we describe this clinical presentation and discuss our management of this aneurysm in the context of the wider, yet limited literature body.

[Open abdominal trauma with inferior vena cava injury]. / Sluchai sochetannoi otkrytoi travmy zhivota s povrezhdeniem nizhnei poloi veny.

The authors report surgical treatment of a patient with a penetrating abdominal trauma followed by damage to inferior vena cava, liver, duodenum and pancreas, massive bleeding and large retroperitoneal hematoma. Suturing of inferior vena cava defect, liver and pancreas, Billroth II gastric resection, drainage of retroperitoneal space and abdominal cavity were carried out. Postoperative period was complicated by pneumonia and seroma in lesser sac that required percutaneous puncture. Antibiotic therapy was used postoperatively. The patient was discharged in 25 days after surgery.

The outcomes of interventional treatment for Budd-Chiari Syndrome complicated by inferior vena cava thrombosis: Systematic review and meta-analysis / Resultados del tratamiento intervencionista del síndrome de Budd-Chiari agravado por trombosis de la vena cava inferior: Una revisión y un metaanálisis sistemáticos

Purpose: The aim of this study was to perform a systematic review and meta-analysis to assess the safety and efficacy of interventional treatment for Budd-Chiari syndrome (BCS) complicated by Inferior Vena Cava thrombosis (IVCT) patients. Methods: We evaluated the published studies on interventional treatment for BCS complicated by IVCT. Meta-analysis was used to calculate the combined effect size and their 95% confidence intervals (CI) based on random effect. The publication bias was assessed by Begg's test. Results: Sixteen studies on interventional treatment for BCS complicated by IVCT patient were selected for meta-analysis, a total of 767 BCS complicated by IVCT patients were included. The combined effect size (95% CI) were 99% (98–100%) for the total successful rate of IVC recanalization, 15% (11–21%) for the rate of IVC restenosis after initial operation, 92.0% (86–97%) for the rate of clinical improvement, 76% (68–84%) for the rate of thrombus clearance and 0.00% (0–1%) for the incidence of pulmonary embolism (PE). Through subgroup meta-analysis about the rate of thrombus clearance, we got the pooled results (95% CI) of individualized treatment strategy (ITS) group and non-individualized treatment strategy (non-ITS) group, were 81% (71–92%) and 73% (63–83%), respectively. Conclusions: The interventional treatment for BCS complicated by IVCT patients is safe and effective with low incidence of PE, high thrombus clearance rate, high technically successful rate, good patency, and high clinical improvement rate. Moreover, subgroup analysis indicated that management based on the type and extent of the thrombus is proposed.(AU)

High Mortality and Venous Thromboembolism Risk Following Major Penetrating Abdominal Venous Injuries.

BACKGROUND: Penetrating injuries to the inferior vena cava and/or iliac veins are a source of hemorrhage but may also predispose patients to venous thromboembolism (VTE). We sought to determine the relationship between iliocaval injury, VTE and mortality. METHODS: The National Trauma Data Bank was queried for penetrating abdominal trauma from 2015-2017. Univariate analyses compared baseline characteristics and outcomes based on presence of iliocaval injury. Multivariable analyses determined the effect of iliocaval injury on VTE and mortality. RESULTS: Of 9,974 patients with penetrating abdominal trauma, 329 had iliocaval injury (3.3%). Iliocaval injury patients were more likely to have a firearm mechanism (83% vs. 43%, P < 0.001), concurrent head (P = 0.036), spinal cord (P < 0.001), and pelvic injuries (P < 0.001), and higher total injury severity score (median 20 vs. 8.0, P < 0.001). They were more likely to undergo 24-hr hemorrhage control surgery (69% vs. 17%, P < 0.001), but less likely to receive VTE chemoprophylaxis during admission (64% vs. 68%, P = 0.04). Of patients undergoing iliocaval surgery, 64% underwent repair, 26% ligation, and 10% unknown. Iliocaval injury patients had higher rates of VTE (12% vs. 2%), 24-hr mortality (23% vs. 2.0%) and in-hospital mortality (33% vs. 3.4%) (P < 0.001 for all). VTE rates were similar following repair (14%) and ligation (17%). Iliocaval injury patients also had higher rates of cardiac complications (10.3% vs. 1.4%), acute kidney injury (8.2% vs. 1.3%), extremity compartment syndrome (4.0 vs. 0.2%), and unplanned return to OR (7.9% vs. 2.5%) (P < 0.001 for all). In multivariable analyses, iliocaval injury was independently associated with risk of VTE (OR 2.12; 95% CI, 1.29-3.48; P = 0.003), and in-hospital mortality (OR = 9.61; 95% CI, 4.96-18.64; P < 0.001). CONCLUSION: Iliocaval injuries occur in <5% of penetrating abdominal trauma but are associated with more severe injury patterns and high mortality rates. Regardless of repair type, survivors should be considered high risk for developing VTE.

Imaging in traumatic injury to the inferior vena cava.

Inferior vena cava (IVC) injury is a rare but serious consequence of trauma. It presents with high scores on trauma assessment scales and is often life threatening. Factors that contribute to poor survival include delay and difficulty in diagnosis due to non-specific clinical features. As it is a relatively rare entity, imaging in IVC injury is not well described in the literature. As radiologists, it is vital that features of potential IVC injury are recognised promptly and findings relayed to the treating clinician in a timely manner to improve survival and reduce the risk of possible complications. Imaging features that should alert radiologists to IVC injury include contour abnormalities, active extravasation, pseudoaneurysm, and pericaval haematoma. Trauma to the IVC is associated with significant complications. These include exsanguination and refractory shock in the acute period while in the longer term, thrombosis can develop with potential for subsequent pulmonary embolism. Additionally, there are complications that may develop post-surgically including further haemorrhage, IVC stenosis, and infection. We review the spectrum of imaging findings in traumatic IVC injury, which are exemplified with cases from our practice. Furthermore, we discuss important factors to consider during interpretation and the challenges that a radiologist may encounter when making the diagnosis.

A Systematic Review and Meta-Analysis of Ligation Versus Repair of Inferior Vena Cava Injuries.

OBJECTIVE: Inferior vena cava (IVC) injuries have a high mortality rate that may be related to the location of injury and type of repair. Previous studies have been either single center series or database studies lacking granular detail. These have reported conflicting results. We aimed to perform a systematic review and meta-analysis of published literature evaluating ligation versus repair. METHODS: Studies published in English on MEDLINE or EMBASE from 1946 through October 2018 were examined to evaluate mortality among patients treated with ligation versus repair of IVC injuries. Studies were included if they provided mortality associated with ligation versus repair and reported IVC injury by level. Risk of bias was assessed regarding incomplete and selective outcome reporting with Newcastle-Ottawa score of 7 or higher to evaluate study quality. We used a random-effects model with restricted maximum likelihood estimation method in R using the Metafor package to evaluate outcomes. RESULTS: Our systematic review identified 26 studies, of which 14 studies, including 855 patients, met our inclusion criteria for meta-analysis. IVC ligation was associated with higher mortality than IVC repair (OR: 3.12, P < 0.01, I2 = 49%). Ligation of infrarenal IVC injuries was not statistically associated with mortality (OR: 3.13, P = 0.09). Suprarenal injury location compared to infrarenal (OR 3.11, P < 0.01, I2 = 28%) and blunt mechanism compared to penetrating (OR: 1.91, P = 0.02, I2 = 0%) were also associated with higher mortality. CONCLUSIONS: In this meta-analysis, ligation of IVC injuries was associated with increased mortality compared to repair, but not specifically for infrarenal IVC injuries. Suprarenal IVC injury, and blunt mechanism was associated with increased mortality compared to infrarenal IVC injury and penetrating mechanism, respectively. Data are limited regarding acute renal injury and venous thromboembolic events after IVC ligation and may warrant multicenter studies. Standardized reporting of IVC injury data has not been well established and is needed in order to enable comparison of outcomes across institutions. In particular, reporting of injury location, severity, and repair type should be standardized. A contemporary prospective, multicenter study is needed in order to definitively compare surgical technique.
