Post-mortem changes of the vascular system-a thanatological study using multidetector computed tomography.

Forensic pathologists have to deal with post-mortem changes of the human body. Those post-mortem phenomena are familiar and largely described in thanatology. However, knowledge about the influence of post-mortem phenomena on the vascular system is more limited, except for the apparition and development of cadaveric lividity.

Structured team-oriented program to follow patients after vena cava filter placement: a step forward in improving quality for filter retrieval.

To reduce inferior vena cava filter (IVCF) related complications, retrieval is recommended whenever possible. Nevertheless, IVCF retrieval rates remain lower than expected, likely due to insufficient follow-up after placement. We evaluated the value of a structured program designed to follow patients by the interventional radiology team up to 5 months after IVCF placement.

Safety of elective percutaneous peripheral revascularization in outpatients: A 10-year single-center experience.

Purpose: To evaluate the safety and feasibility of peripheral percutaneous endovascular procedures in a large group of outpatients with peripheral arterial disease (PAD).

Materials And Methods: We retrospectively evaluated all consecutive patients who underwent peripheral transluminal angioplasty (PTA) for PAD of the lower extremities as "Out-Patient Admission Protocol" (OPAP) from January 2005 until December 2015. A total of 498 consecutive patients (305 men and 193 women) with mean age of 66±10 (SD) years (range: 37-90 years) were evaluated.

Visualization of Myocardial Infarction in Postmortem Multiphase Computed Tomography Angiography: A Feasibility Study.

Recent studies have indicated that multiphase postmortem computed tomography angiography (MPMCTA) allows detection of a pathological enhancement of the myocardium in regions that correlate with the localization of the infarction at histology. The aim of this study was to verify this hypothesis by examining MPMCTA images in cases of myocardial infarction. Therefore, we investigated 10 autopsy cases where death was attributed to myocardial infarction or which showed cardiovascular pathology.

Superior Vena Cava (SVC) Endovascular Reconstruction with Implanted Central Venous Catheter Repositioning for Treatment of Malignant SVC Obstruction.

Superior vena cava (SVC) syndrome is a group of clinical signs caused by the obstruction or compression of SVC and characterized by edema of the head, neck, and upper extremities, shortness of breath, and headaches. The syndrome may be caused by benign causes but most of the cases are caused by lung or mediastinal malignant tumors. Stenting of SVC has become widely accepted as the palliative treatment for this condition in malignant diseases, as it offers rapid relief of symptoms and improves the quality of life.

The role of angiography in the congruence of cardiovascular measurements between autopsy and postmortem imaging.

Introduction: Postmortem CT angiography is the method of choice for the postmortem imaging investigations of the cardiovascular (CV) system. However, autopsy still remains the gold standard for CV measurement. Nevertheless, there are not any studies on CV measurements on the multi-phase postmortem angiography (MPMCTA) which includes comparisons with autopsy.

Brachial Approach As an Alternative Technique of Fibrin Sheath Removal for Implanted Venous Access Devices.

Implanted venous access device (IVAD) late dysfunction is commonly caused by fibrin sheath formation. The standard method of endovascular fibrin sheath removal is performed the femoral vein. However, it is not always technically feasible and sometimes contraindicated.

A Case of Gastro-Duodenal Artery Aneurism: Treatment and Complications.

We present the case of a 75-year-old patient with asymptomatic gastro-duodenal artery aneurism (GAA) that was coiled through the left femoral artery. The gastro-duodenal artery (GDA) was then embolized. Following the intervention, the patient'™s left foot became cold.

Percutaneous endovascular management of chronic superior vena cava syndrome of benign causes : long-term follow-up.

Background: The vast majority of superior vena cava (SVC) syndromes are of malignant causes, but with growing use of indwelling central catheters and implanted cardiac devices, benign SVC syndromes are becoming more frequent. The main objective of this study is to evaluate long term outcome in patients treated for benign SVC syndrome by endovascular techniques.

Methods: Forty-four patients, 26 men and 18 women, mean age 56, treated for benign SVC syndrome using endovascular techniques between 2002 and 2015 were included.

The cardiothoracic ratio on post-mortem computer tomography.

In clinical practice, the cardiothoracic ratio (CTR) was first utilized on plain chest radiography, and subsequently with computed tomography (CT) to diagnose cardiomegaly with a threshold of 0.5. Using CTR in forensic practice could help to detect cardiomegaly on post-mortem CT (PMCT) prior to the autopsy.

Pathomorphological and CT-angiographical characteristics of coronary atherosclerotic plaques in cases of sudden cardiac death.

The goal of this study was to assess the localization and types of thrombosed plaques in cases of sudden cardiac death attributed to coronary artery disease and to evaluate possible correlations with body mass index (BMI) and increased heart weight. This retrospective study was performed on forensic cases for which the cause of death was attributed to coronary artery disease. A complete autopsy and a multi-phase postmortem computed tomography (CT) angiography (MPMCTA) were performed in all cases.

Application of multi-phase postmortem CT-angiography in the investigation of vascular pathology and modified vascular anatomy: a special case of "vascular patchwork".

Multi-phase postmortem CT-angiography (MPMCTA) is used routinely for investigating cases of traumatic and natural death at the University Centre of Legal Medicine, Lausanne-Geneva. Here, we report the case of a patient affected by Leriche syndrome, with a history of numerous cardiovascular interventions, including an axillobifemoral bypass. The multiple cardiovascular changes presented by the patient were visualised by this relatively new technique and they were shown not to be related to the cause of death.

[Treatment of critical lower limb ischemia].

Critical limb ischemia is a major public health problem in our western countries due to the epidemia of (diabesity). The outcome of patients suffering from critical limb ischemia reains poor with an amputation free survival rate at one year of about 50%. The treatment should be multidiciplinary and done in emergency in specialized centers to ensure the limb salvage: this management should be centered aroud 3 axis: the screening of the cardiovascular risk factors, the best medical treatment and the invasive approaches.

Percutaneous endovascular salvage techniques for implanted venous access device dysfunction.

Purpose: Implanted venous access devices (IVADs) are often used in patients who require long-term intravenous drug administration. The most common causes of device dysfunction include occlusion by fibrin sheath and/or catheter adherence to the vessel wall. We present percutaneous endovascular salvage techniques to restore function in occluded catheters.

Computer Aided Detection and measurement of peripheral artery disease.

Computer-Aided Tomography Angiography (CTA) images are the standard for assessing Peripheral artery disease (PAD). This paper presents a Computer Aided Detection (CAD) and Computer Aided Measurement (CAM) system for PAD. The CAD stage detects the arterial network using a 3D region growing method and a fast 3D morphology operation.

Acute aortic dissection with carotid and coronary malperfusion: from imaging to pathology.

Postmortem imaging, including postmortem computed tomography angiography, has become an integral tool in forensic investigation in recent years. A relatively new technique, multiphase postmortem computed tomography angiography, allows detailed visualization of the vascular system and makes it possible to evaluate the dynamic perfusion of aortic branches, including the coronary arteries. Here, we report a case of aortic dissection involving the ascending aorta (type A) with coronary and carotid malperfusion.

Acute coronary syndrome after levamisole-adultered cocaine abuse.

Cocaine is a well known trigger of acute coronary syndromes. Over the last 10 years levamisole, a veterinary anthelminthic drug has been increasingly used as an adulterant of cocaine. Levamisole was used to treat pediatric nephritic syndrome and rheumatoid arthritis before being withdrawn from the market due to its significant toxicity, i.

[Primary hyperaldosteronism with adrenal adenoma or hyperplasia: surgical case or not?].

Primary hyperaldosteronism is one of the most frequent causes of secondary hypertension. Cardiovascular morbimortality is higher than in essential hypertonic and justifies diagnostic and specific treatment of this pathology. Therapeutic choice depends of health and desire of the patient.

[Popliteal artery aneurysms: management in 2013].

Although rare, popliteal artery aneurysms are the most common peripheral aneurysms and are frequently associated with abdominal aorta aneurysms. They are often bilateral. One third of patients are asymptomatic at diagnosis, with an insidious evolution.

Multi-phase postmortem CT angiography: recognizing technique-related artefacts and pitfalls.

Background And Purpose: Multi-phase postmortem CT angiography (MPMCTA) is increasingly being recognized as a valuable adjunct medicolegal tool to explore the vascular system. Adequate interpretation, however, requires knowledge about the most common technique-related artefacts. The purpose of this study was to identify and index the possible artefacts related to MPMCTA.

Postmortem imaging of sudden cardiac death.

Postmortem imaging is increasingly used in forensic practice in cases of natural deaths related to cardiovascular diseases, which represent the most common causes of death in developed countries. While radiological examination is generally considered to be a good complement for conventional autopsy, it was thought to have limited application in cardiovascular pathology. At present, multidetector computed tomography (MDCT), CT angiography, and cardiac magnetic resonance imaging (MRI) are used in postmortem radiological investigation of cardiovascular pathologies.

Postmortem computed tomography angiography vs. conventional autopsy: advantages and inconveniences of each method.

Purpose: Postmortem computed tomography angiography (PMCTA) was introduced into forensic investigations a few years ago. It provides reliable images that can be consulted at any time. Conventional autopsy remains the reference standard for defining the cause of death, but provides only limited possibility of a second examination.
