INTRODUCTION AND IMPORTANCE: Raghib syndrome is a rare congenital complication consisting of the termination of the left superior vena cava (LSVC) in the left atrium, an unroofed coronary sinus, and an atrial septal defect most often found in the posterior-inferior angle of the atrial septum. Both a right-to-left and a left-to-right intracardiac shunt exist. In most circumstances, they do not show any symptoms. PRESENTATION OF CASE: The patient presented with a persistent left superior vena cava draining into the left atrium, an unroofed coronary sinus, and a secondary atrial septal defect (ASD)...

BACKGROUND: In the intensive care unit (ICU) patients, fluid overload and congestion are associated with worse outcomes. Because of the heterogeneity of ICU patients, we hypothesized that there may exist different endotypes of congestion. The aim of this study was to identify endotypes of congestion and their association with outcomes. METHODS: We conducted an unsupervised hierarchical clustering analysis on 145 patients admitted to ICU to identify endotypes. We measured several parameters related to clinical context, volume status, filling pressure, and venous congestion...

This study proposes a novel inferior vena cava filter (IVCF) design, "Lotus," aiming to enhance release stability and endothelialization. A catheter-filter-vessel model was established for IVCF property analysis, validated by comparing numerical simulations and in vitro tests. Lotus's mechanical properties were analyzed, and optimization suggestions are provided. Compared to existing clinical filters, Lotus demonstrates improved release stability and thrombus capture ability. This work suggests Lotus as a potential technical reference for improved IVCF treatment...

During the fetal period, oxygenated blood from the placenta flows through the umbilical vein (UV), portal sinus, ductus venosus (DV), and inferior vena cava (IVC) to the heart. This venous route varies regionally in many aspects. Herein, we sought to characterize the venous route's morphological features and regional differences during embryonic and early-fetal periods. Twenty-nine specimens were selected for high-resolution digitized imaging; 18 embryos were chosen for histological analysis. The venous route showed a primitive, large, S-shaped curved morphology with regional narrowing and dilation at Carnegie stage (CS) 15...

AIMS: Regulation of the renin-angiotensin system (RAS) in heart failure (HF) with reduced ejection fraction (HFrEF) still raises questions, as a large proportion of patients show normal renin levels despite manifest disease. Experimental venous congestion results in reduced renal perfusion pressure and stimulates renin secretion. We hypothesized that excess renin levels are mainly a result of right ventricular failure as a sequalae of left ventricular dysfunction. The study aimed to link right ventricular function (RVF) with renin levels and to investigate further contributors to excess RAS activation...

PURPOSE: Combining resuscitative endovascular balloon occlusion of the aorta (REBOA) and the inferior vena cava (REBOVC) with open surgery is a new hybrid approach for treating retrohepatic vena caval injuries. We compared endovascular total hepatic isolation with supraceliac REBOA ± suprahepatic REBOVC and no occlusion in experimental retrohepatic vena cava bleeding regarding survival, bleeding volume, hemodynamic stability, and arterial collateral blood flow. METHODS: Twenty-five anesthetized pigs (n = 6-7/group) were randomized to REBOA; REBOA + REBOVC; REBOA + infra and suprahepatic REBOVC + portal vein occlusion (endovascular Heaney maneuver, four-balloon-occlusion, 4BO) or no occlusion...

Ovarian vein thrombosis (OVT) is a rare but serious complication, most commonly occurring in the postpartum period. This article reports the case of a 40-year-old woman who presented 12 days after a normal vaginal delivery with fever and pelvic pain. An initial diagnosis of endometritis was made, and empiric antibiotic therapy was administered, but the fever persisted. An ultrasound scan was then done to rule out appendicitis, which revealed a thrombosis of the right ovarian vein extended to the inferior vena cava...

Point-of-care ultrasound (POCUS) of the internal jugular vein (IJV) offers a non-invasive means of estimating right atrial pressure (RAP), especially in cases where the inferior vena cava is inaccessible or unreliable due to conditions such as liver disease or abdominal surgery. While many clinicians are familiar with visually assessing jugular venous pressure through the internal jugular vein, this method lacks sensitivity. The utilization of POCUS significantly enhances the visualization of the vein, leading to a more accurate identification...

We report a case of a robotic-assisted excision of a retrocaval ancient schwannoma. A 40-year-old female presented with generalized weakness and abdominal pain that led to the diagnosis of a retroperitoneal mass adjacent to the pancreas and inferior vena cava. Because of the clinical, imaging, and needle biopsy findings, the patient underwent an elective robotic-assisted retroperitoneal exploration. We provide an overview of the pathology and highlight the significance of utilizing a minimally invasive approach for excision of retroperitoneal masses...

The presence of a cysto-caval fistula is a serious and rare complication of hepatic hydatid cysts, which can be life-threatening. We report a case of a 22-year-old patient with a segment I hepatic hydatid cyst discovered following scannographic imaging for non-specific abdominal pain. Management consisted of albendazole-based premedication for two weeks, followed by hepatic and venous resection surgery with prosthetic replacement after venous exclusion under extracorporeal circulation. To avoid hemorrhagic and/or embolic complications, it is essential to discuss rare cases of hydatid cysts with intimate contact or invasion of the vena cava in a multidisciplinary setting, to plan repair or reconstruction away from intraoperative surprises that are often fatal for benign pathology...

BACKGROUND: The gold standard treatment for renal cell carcinoma (RCC) with tumor thrombus (TT) is complete surgical excision. The surgery is complex and challenging to the surgeon, especially with large tumor thrombus extending into the inferior vena cava (IVC) and right atrium. Traditionally, these difficult cases required the use of cardiopulmonary bypass (CPB) with or without deep hypothermic cardiac arrest, but in recent years, different surgical techniques derived from the field of liver transplantation have been used in efforts to avoid CPB...

Glomus tumor, arising from glomus bodies (specialized neurovascular structures involved in thermoregulation), commonly occurs in extremities and rarely in viscera. The spectrum of glomus tumors range from benign tumors to tumors with uncertain malignant potential to tumors of the malignant subtype. A vast majority of visceral glomus tumors are benign. Most common visceral tumors arise in the gastrointestinal tract. Glomus tumors of the kidney are a rare entity of which malignant glomus tumors are exceedingly rare...

We present a 58-year-old female patient who underwent resection of a leiomyosarcoma arising from the right ovarian vein. She was referred to our hospital because of lower abdominal pain that had been present for 1 month prior to the visit. Ultrasound examination revealed a well-defined, smooth, lobulated, highly vascular mass(57 mm)adjacent to the distal portion of the duodenum. Contrast-enhanced computed tomography revealed the contrast enhancement mass (60 mm)located surround the right ovarian vein. In abdominal magnetic resonance image examination, the mass exhibited isointense signal on T1-weighted images, high signal on T2-weighted images, and restricted diffusion on diffusion- weighted images...

PURPOSE: In the modern era of robotic renal procedures and diagnostics, an even more detailed anatomical understanding than hitherto is necessary. Valves of the renal veins (RVV) have been underemphasized and have been disputed by some authors, and few textbooks describe them. The current anatomical study was performed to address such shortcomings in the literature. METHODS: One hundred renal veins were studied in fifty adult formalin-fixed cadavers. Renal veins were removed from the abdomen after sectioning them flush with their entrance to the renal hilum...
