Invasion of Pheochromocytoma from the Caudal Vena Cava to the Right Ventricular Cavity in a Dog

Pheochromocytomas are catecholamine-secreting tumors that are composed of neuroectoderm-derived chromaffin cells. An 8-year-old miniature dachshund with abdominal distension was diagnosed with a neuroendocrine tumor with invasion from the caudal vena cava to the right ventricular cavity. The dog died due to hypotensive shock from the vagal reflex, and on autopsy, an extra-adrenal pheochromocytoma (paraganglioma) was diagnosed in the caudal abdomen. At autopsy, the tumor plug of the caudal vena cava was confirmed. To the best of our knowledge, this is the first case report that echo-captured the extension of pheochromocytoma in the right ventricle and shows it in a figure and video file.

Intravenous leiomyomatosis is extremely rare. This case describes a 42-year-old woman who presented with abdominal distension, cyclical bloating and urinary retention. Preoperative imaging showed a multilobulated uterine mass. Following multidisciplinary team discussion, a complete staging surgery consisting of midline laparotomy, total hysterectomy and bilateral salpingo-oophrectomy was performed. Intraoperatively, a large multilobulated uterine mass was noted with engorgement of the infundibulopelvic ligaments due to intravascular extension of tumour. On removal of the uterus, the patient desaturated and became hypotensive. Intraoperative transoesophageal echocardiography revealed mass extending from the inferior vena cava (IVC) into the right atrium (RA). The cardiothoracic surgical team retrieved a worm-like mass extending from the IVC into the RA. Histopathological examination diagnosed a large uterine leiomyoma with intravenous leiomyomatosis. The mass from the RA was a bland spindle cell tumour which matched the uterine mass histopathologically. Intravenous leiomyomatosis is a rare variant of uterine leiomyoma. Although intracardiac extension has been described, this is the first case of intraoperative embolisation of pelvic tumour to the RA at hysterectomy.

Abstract Background Emphysematous pyelonephritis (EPN) with gas in the inferior vena cava (IVC) is a rare presentation and to our knowledge, this is the first case report in the urologic literature. Case presentation A 35-Year-old obese diabetic Hispanic female presented to the emergency room with a clinical picture of septic shock. Prompt computerized tomography scan revealed EPN with gas throughout the right renal parenchyma and extending to the right renal vein, IVC, and pulmonary artery. She died before surgical intervention Conclusion This case demonstrates that patients presenting with severe EPN have a high mortality risk and providers should acknowledge that septic shock, endogenous air emboli, or a combination of both could result in cardiovascular collapse and sudden death.

Acceleration Stress

Measurements of right ventricular pressure in miniature swine were made at +Gz levels from +1 through +9 Gz. Polyethylene catheters were chronically placed in the cranial vena cava of five 2-yr-old female miniature swine (35–50 kg). The catheters were large enough to allow the introduction of a Millar pressure transducer into the venous system for placement in the right heart. The animals were fitted with an abdominal anti-G suit, restrained in a fiberglass couch, and exposed to the various +Gz levels on a centrifuge while fully conscious and unanesthetized. Right ventricular pressure and heart rate were measured during and for 2 min following 30-s exposures to each level of +Gz stress. The maximum right ventricular systolic pressure observed during +Gz was 200 Torr at +5 Gz with the maximum diastolic pressure being 88 Torr observed at +5 Gz. Mean heart rates were 200–210 beats/min at all levels of +Gz greater than or equal to +3 Gz when the animal remained stable. Mean maximum right ventricular pressures during +Gz stress were observed to increase through +5 Gz (85 Torr) and to decrease at higher levels of +Gz, indicating that through +5 Gz there is at least a partial compensation during acceleration stress. Decompensation in response to the stress began to occur during acceleration above +5 Gz with all animals decompensating during +9 Gz.

Aim. To justify and develop method of endocardial electrode reposition in the right ventricular cavity of the heart in the spontaneous termination of temporary pacing in patients with recurrent myocardial infarction.Methods. A method of endocardial electrode reposition was used in 23 patients with myocardial infarction complicated by acute bradyarrhythmias. Written informed consent was obtained from all patients, and in the absence of contact with the patient, decision to insert temporary artificial pacemaker was made by medical consultation.Results. A method of endocardial electrode reposition that provides threading the electrode from the venous bed to the right ventricular cavity of the heart, cardiac stimulation by electrical impulses and creation the new contacts between electrode and right ventricular endocardium of the heart using the same electrode, both in the presence and in absence of the heart conduction and excitation function, was developed. At the same time, it excludes the electrode dislocation from the right ventricular cavity of the heart, provides the electrode fixation with endocardium, and at the same time allows to impose a stable artificial heart rhythm in the shortest time. During the spontaneous termination of the effective artificial pacemaker, endocardial electrodes reposition enabled to promptly regain the heart rhythm control in all 23 patients with acute bradyarrhythmia of infarction genesis.Conclusion. Effective and safe method of endocardial electrode reposition in the right ventricular cavity of the heart in the spontaneous termination of temporary pacing in patients with recurrent myocardial infarction was developed and introduced into clinical practice.

Abstract Funding Acknowledgements governmental grants Uterine leiomyoma is a commom disease in women, however, intravenous leiomyomatosis of uterine origin extending via inferior vena cava into the right side of the heart,known as intracardiac leiomyomatosis is a rare condition (3%). In 1907, Durk reported the first case of intracardiac extension. The patient was a Woman, 35 years old, admitted to our emergency department for an intracardiac mass. She had shortness of breath,fatigue and chest pain. The transthoracic two dimensional echocardiography showed an echogenic oval mass mobile in right atrium and projected through right ventricle in diastole. This mass was observed to extend from inferior vena cava to the right atrium. The echotransesophageal three dimensional showed a large mobile mass that extended from inferior vena cava to the right atrium. A Computer tomographic (CT) scan showed a hypodense multilobulated mass in the pelvis, which had invaded the inferior vena cava and right atrium. The patient underwent a two stages surgery. In first stage (transatrial tumor resection). The operation was performed normal temperature with establisment of cardiopulmonary bypass (CPB). Subsequently, the pathological report was confirmed uterin smooth muscle origin. The second stage surgery ( total histerectomy) was done four weeks later for removing lobulated mass uterin with dimensions 20x15x7.5cm with confirmed histopathological of leiomyoma. Because of it is nonspecific clinical presentation and rarity, an intracardiac Leiomyomatosis continues to be a misdiagnosed as either thrombus or myxoma. The cardiac imaging techniques like a transthoracic echocardiography 2d and transesophageal echocardiography 3d have been used to define the presence, extension of tumor as appearance of the mass and involvement of adjacent structures.

Cavopulmonary Shunt

The left superior vena cava became occluded in an infant with hypoplastic left heart syndrome. After a bidirectional Glenn procedure, he presented with severe oxygen desaturation and right ventricular dysfunction; the left superior vena cava drained into the inferior vena cava through collateral veins. As salvage therapy, we created a modified total cavopulmonary shunt using only autologous tissue in which the right hepatic vein and inferior vena cava drained into the pulmonary artery via a lateral tunnel in the right atrium. Immediately after surgery, his oxygen saturation increased and right ventricular function improved.
