    Massive subchorial thrombosis (MSCT) is a placental abnormality, the etiology and pathogenesis of which remain inadequately studied. MSCT is characterized by a clinical symptom complex comprising marked intrauterine growth retardation, oligohydramnios, and fetal distress due to placental circulatory problems. Perinatal outcomes are appreciably determined by the term of pregnancy, the degree of placental insufficiency, and neonatal status. Prolonged MSCT makes it possible to diagnose this pathology by echographic and magnetic resonance imaging studies and to attempt to treat placental dysfunction through tocolytic therapy and correction of oligohydramnios, to prolong pregnancy, and to have a viable newborn infant. The clinical and morphological diagnosis of MSCT calls for its differential diagnosis with other focal placental lesions, such as subamniotic, intraplacental, and retroplacental hematomas, cytotrophoblastic cyst, umbilical cord cysts, and chorangioma.

    Venous Thrombosis I: Introduction

    Venous thrombosis, the most common disorder of the veins, involves the formation of a thrombus or blood clot associated with vein inflammation. It can be classified as either superficial vein thrombosis or deep vein thrombosis.Superficial Vein Thrombosis: This involves the formation of a thrombus in a superficial vein, usually the greater or lesser saphenous vein. Though less severe than deep vein thrombosis (DVT), SVT can lead to complications if untreated.Deep Vein Thrombosis (DVT): This...

    Venous Thrombosis III: Interprofessional Care

    Venous thrombosis requires effective prevention and treatment strategies to improve patient outcomes and reduce potential complications.Prevention StrategiesHealthcare providers must prioritize preventing venous thromboembolism (VTE) for all adult patients upon admission. Interventions depend on bleeding and thrombosis risk, medical history, current medications, diagnoses, planned procedures, and patient preferences. Patients on bed rest should change positions every two hours and, if not...

    Venous Thrombosis II: Clinical Manifestations and Diagnostic Studies

    The key difference between Superficial Vein Thrombosis (SVT) and Deep Vein Thrombosis (DVT) lies in their location and severity.Clinical ManifestationsSVT typically presents with localized pain, tenderness, and redness along the course of a superficial vein, often accompanied by a palpable, cord-like structure under the skin. This condition is usually less dangerous than DVT but can be uncomfortable and may lead to complications such as cellulitis or, rarely, a clot extension into the deep...

    Thoracic Aorta

    The thoracic section of the aorta begins at the T5 vertebra and extends to the T12 level at the diaphragm, initially progressing through the mediastinum to the left of the spinal column. Throughout its course in the thoracic segment, the thoracic aorta emits various offshoots known collectively as visceral and parietal branches. The branches that predominantly supply blood to visceral organs are termed visceral branches and include bronchial, pericardial, esophageal, and mediastinal arteries,...

    Aneurysm II: Clinical Manifestations and Diagnostic Studies

    Thoracic, aortic arch and abdominal aneurysms are significant vascular conditions that can present with various clinical manifestations and lead to serious complications. Understanding these manifestations and the appropriate diagnostic studies is essential for effective management and treatment.Thoracic Aortic AneurysmsThoracic aortic aneurysms often remain asymptomatic until they reach a size that impinges on adjacent structures. They typically cause deep, diffuse chest pain that radiates to...

    Hemorrhagic Stroke ll: Pathophysiology

    A hemorrhagic stroke develops when a cerebral blood vessel ruptures, allowing blood to escape into the surrounding brain tissue, as in intracerebral hemorrhage (ICH), or into the subarachnoid space, as in subarachnoid hemorrhage (SAH). Because the skull is a rigid compartment, the sudden presence of extravascular blood rapidly increases intracranial pressure and compresses adjacent neural structures, leading to immediate tissue injury and impaired cerebral perfusion.Mass Effect and Primary...
