תסחיף ריאתי (ת"ר) הוא מצב שכיח בתחומי רפואה שונים והסתמנותו הקלינית מגוונת. הביטויים השכיחים כוללים קוצר נשימה פתאומי, כאב צידרי (pleural pain), שיעול, גניחת-דם ועילפון. טאכיפנאה, טאכיקרדיה, גודש ורידי צוואר והיפוקסמיה. שיעור התמותה מת"ר הוא 6%-8%, למרות טיפול, אך בחולים עם ת"ר המלווה בירידת לחץ-דם, עלול שיעור התמותה להגיע עד 30%.

מצב קליני קשה יותר הוא תסחיף ריאתי מסיבי (תר"מ). זהו מצב מסכן חיים, הכרוך בשיעור תמותה גבוה ביותר ומחייב טיפול מיידי. מרבית החולים (60%-70%) עלולים למות תוך 1-6 שעות מתחילת התסמינים, אם לא יוחל טיפול. הטיפול בחולה עם תר"מ מחייב שיתוף פעולה של צוות רפואי הכולל את הרופאים המטפלים, אנשי דימות פולשני, יחידה לטיפול נמרץ ומנתחי לב. ההחלטות חייבות להתקבל במהירות על סמך הוריות המעוגנות בתוצאות מחקרים, אך מביאות בחשבון את הידע והניסיון המקומי של הצוות הרפואי.

המטרה בסקירה הנוכחית היא לדון בהיבטים השונים של הטיפול בחולה עם תר"מ, על סמך המידע בספרות ועל סמך הניסיון שרכשנו בטיפול במספר חולים עם תר"מ בשנים האחרונות, תוך ניסיון לשתף את קהל הקוראים בתרשימי הזרימה לטיפול, שגובשו במחלקתנו.

Two cases of severe hepatic injury in which selective hepatic artery embolization was used to control hemorrhage are presented. The first case is that of a 35 year old patient who sustained a severe liver injury after a car accident. A CAT scan of the abdomen revealed an AAST grade 5 liver injury, pooling of contrast material within the liver parenchyma, and blood within the peritoneal cavity. The patient was given fluid resuscitation and taken to angiography where bleeding from branches of the right hepatic artery was demonstrated. While angiography was being undertaken the hemodynamic status of the patient deteriorated, blood transfusion was started, and a selective embolization of the right hepatic artery was performed. The bleeding stopped promptly and hemodynamic stability was regained.

The second case is that of a 40 year old pedestrian run over by a car. Abdominal ultrasound revealed free fluid in the peritoneal cavity and the patient was rushed to the O.R. Crushed right lobe of the liver, and inferior vena cava and bowel tears were found. After perihepatic packing and resection of the right and sigmoid colons retrohepatic vena cava tear was repaired and perihepatic packing restored. The abdominal cavity was closed and the patient was taken to the ICU for the correction of hypothermia, metabolic acidosis, and coagulopathy that had developed during the surgery. After 8 hours in the ICU the patient was transferred for angiography and a selective embolization of branches of the right hepatic artery was performed.

The clinical course of the patients after angiographic embolization of the hepatic arteries is described and the literature that discusses the use of angiography and embolization of hepatic arteries after traumatic hepatic bleeding is reviewed.

Atrophic Gastritis Presenting with Pulmonary Embolism

Atrophic gastritis is an autoimmune gastropathy in which there is destruction of gastric parietal cells. This results in intrinsic factor deficiency and disturbance in vitamin B12 absorption. Its clinical manifestationa are therefore the consequences of B12 deficiency and include anemia and neurological defect. In addition, lack of B12 results in metabolic changes, including disturbances of methionine metabolism and accumulation of homocysteine.

In recent years, there has been increasing evidence suggesting that hyperhomocysteinemia is a risk factor for thrombo-embolic disease. We describe a 51-year-old man with atrophic gastritis, severe B12 deficiency and hyperhomocystein-emia. The initial clinical manifestation was pulmonary embolism, without either anemia or neurological signs. B12 deficiency should therefore be considered in patients being investigated for hypercoagulability.

Thromboembolism in Orthopedic Trauma

Trauma increases risk of thromboembolic complications. Thus, in pelvic fractures and spinal injuries the incidence of deep vein thrombosis (DVT) is about 35-60%. Half occur in the pelvic veins and are the most likely to result in pulmonary embolism. While symptomatic pulmonary embolism occurs in 2-10% of patients, more have silent pulmonary embolism. 0.5-2% of pulmonary embolisms are fatal. In lower extremity trauma the incidence of DVT is about 58%, with 18% of them in the proximal veins. Thromboembolic complications are the prime cause of morbidity and mortality among trauma patients, yet they can be prevented efficiently and cost-effectively. The arsenal of prophylactic agents includes heparin, low molecular weight heparin, and mechanical devices including inferior vena cava filters.

Cholesterol crystal embolization can affect multiple organ systems and mimic other systemic diseases. We describe a 65-year-old woman who had renal failure, diarrhea, transient ischemic attacks and purple toes due to spontaneous cholesterol crystal embolization.

The most common invasive procedure performed in hospitals ithe insertion of a vascular access device. This procedure has the rare complication ofcatheter emboli. Accidental cutting of a peripheral catheter, the use of duplex ultrasound to locate the cut and the extraction of the catheter through a venesection is described. If peripheral extraction fails, percutaneous extraction or thoracotomy should be tried, in that order. The immediate precautions have an impact on the final results.

Pulmonary embolism is a common event in hospitalized patients. In some cases it presents with hemodynamic collapse, indicating massive obliteration of the pulmonary vasculature and has a very grim prognosis; 2/3 of such patients die within 2 hours of onset of symptoms. We describe our experience in 13 patients with massive pulmonary embolism. An aggressive diagnostic and therapeutic approach, utilizing sophisticated imaging techniques, thrombolytic therapy and surgery, led to the survival of 8 of the patients. Our experience supports an aggressive approach in these seriously ill patients.

Cerebrovascular events have high mortality and morbidity, especially in the elderly. Ischemia is the main cause and 30% of the ischemic events are embolic and of cardiac origin. The clinical picture is not always typical of the type of stroke, but diagnosis of the mechanism of the event determines treatment. Transesophageal echocardiography (TEE) is a sensitive procedure more appropriate for diagnosing emboli of cardiac origin than transthoracic echocardiography (TTE). We therefor compared TEE and TTE in the determination of the source of emboli in 65 patients with ischemic stroke but without significant atherosclerotic changes in their carotid arteries, and compared these findings with those in 50 patients without stroke. 68% of the patients had potential sources of emboli according to TEE, compared to only 15% according to TTE. In the control group only 24% had potential sources of emboli by TEE. The findings were: clots in the left atrium, severe aortic atheroma, patent foramen ovale with paradoxical shunt, spontaneous echocardiography contrast, vegetations and mitral valve prolapse. The study showed that TEE is better than TTE in detecting the etiology of embolic stroke in those with normal carotid arteries, thus determining appropriate management.

Splenic infarction is a rare disorder. The typical clinical presentation is sudden pain in the left upper quadrant of the abdomen, and awareness to this possibility is the major clue for diagnosis. We describe a 49-year-old man with chronic atrial fibrillation and splenomegaly who was treated with anticoagulants. Because of hematuria, the regular dose of anticoagulant therapy was reduced. The hematuria stopped but he complained of sudden onset of pain in the left upper quadrant. Computerized tomography and isotope scan of the spleen confirmed the clinical suspicion of splenic infarction. Treatment with anticoagulants and analgesics was followed by clinical improvement.

A 9-year-old boy was admitted after a bicycle fall. Abdominal CT-scan revealed severe liver injury (stage IV according to the liver injury scale of the American Association for Surgery Trauma), including ruptured intraparenchymal hematoma with active bleeding. The patient was hemodynamically stable and was treated conservatively for the first 2 days. On the 3rd day selective hepatic artery angiography was performed because of abdominal distension and the need for 7 pints of packed red blood cells. Active right hepatic artery bleeding was identified and treated successfully by embolization. We think that early angiography and selective embolization should always be considered for acute or continuous bleeding after liver injury.
