Mortality And Morbidity

Introduction Heparin induced thrombocytopenia thrombosis Syndrome has a high mortality and morbidity in cardiac surgical patients in spite of early diagnosis and management. We present a case with multiple acute deep venous thrombosis (DVT) after using unfractionated heparin (UFH) during coronary artery bypass graft (CABG) with initiation of HIT antibodies negative. Case presentation A 70-year-old male complained of left leg pain 2 days after CABG for an acute ST-elevation myocardial infarction. Patient was treated with UFH intravenous during CABG. Platelet count was 78 x 109/L that was 130 x 109/L before the procedure. Anti-heparin antibodies IgM/IgG were negative. Venous Doppler ultrasound showed an acute deep venous thrombosis (DVT) in the left peroneal vein. However, after the patient was treated with Coumadin anticoagulation for 7 days with INR in therapeutic range (2-3), the patient presented for right low extremity pain. Platelet count was 40 x 109/L. Anti-heparin antibodies IgM and IgG were repeatedly positive. Venous Doppler ultrasound showed multiple bilateral lower extremities acute DVTs. Patient had thrombectomy and continued with coumadin anticoagulation at INR in therapeutic range for 3 months. Discussion HITTS is an immune-mediated drug reaction that occurs more frequently in patients undergoing cardiovascular surgery. Thrombosis caused by the HIT/T syndrome is most commonly venous thromboembolism. Thrombosis is arterial in about 20% of cases, including acute limb ischemia, myocardial infarction, or stroke. Previous clinical data has shown that about 40% of high titer-negative HIT antibodies were associated with a positive result in repeated testing several days later, which is the same as our presentation. The mortality and morbidity rates of HITTS are approximately 30% and 60%, respectively, and an additional ~10% of patients require amputations or suffer other major morbidity. However, with early recognition and intervention, mortality can be reduced from >30 to <10%. Obviously, repeated testing to identify patients who have HIT despite a negative initial HIT test in several days is greatly recommended. Diagnosis is essentially clinical and negative results from laboratory assays do not exclude the diagnosis.

Deep Vein

Fifty-three patients were examined because of suspected deep venous thrombosis, by means of clinical examination, Doppler ultrasound and venography. Eighty-two legs were examined with all three methods. Venography was positive in 40 and normal in 42. The clinical examination was false positive in 4 legs and false negative in 6. The Doppler ultrasound studies gave false positive results in 3 legs and false negative results in 6. These results are better than those reported in the literature probably because the thrombosis extended to the popliteal vein or the more proximal veins in 38 of the 40 legs with deep vein thrombosis. This high percentage of upper leg vein thrombosis can be explained by the fact that 47 of the 53 patients were ambulant when they developed the signs and symptoms of thrombosis. It is concluded, that the clinical examination and Doppler ultrasonography can be used to diagnose deep vein thrombosis in ambulant patients in our clinic. We presume that the findings reported in the literature cannot be used indiscriminately as a basis for diagnostic strategies in other hospitals because of widely varying categories of patients, referral patterns and diagnostic criteria that are virtually impossible to standardize.

This chapter, found in the bone, joint, and extremity pain section of the book, provides a succinct synopsis of a key study examining the use of Doppler ultrasound for diagnosing suspected lower extremity deep venous thrombosis. This summary outlines the study methodology and design, major results, limitations and criticisms, related studies and additional information, and clinical implications. This study demonstrated that 2-point ultrasonography is equivalent to the whole-leg ultrasonography for diagnosing symptomatic deep venous thrombosis. In addition to outlining the most salient features of the study, a clinical vignette and imaging example are included in order to provide relevant clinical context.

Potential Risk Factors

OBJECTIVEThe risk of venous thromboembolism (VTE) from deep venous thrombosis (DVT) is significant in neurosurgical patients. VTE is considered a leading cause of preventable hospital deaths and preventing DVT is a closely monitored quality metric, often tied to accreditation, hospital ratings, and reimbursement. Adult protocols include prophylaxis with anticoagulant medications. Children’s hospitals may adopt adult protocols, although the incidence of DVT and the risk or efficacy of treatment is not well defined. The incidence of DVT in children is likely less than in adults, although there is very little prospectively collected information. Most consider the risk of DVT to be extremely low in children 12 years of age or younger. However, this consideration is based on tradition and retrospective reviews of trauma databases. In this study, the authors prospectively evaluated pediatric patients undergoing a variety of elective neurosurgical procedures and performed Doppler ultrasound studies before and after surgery.METHODSA total of 100 patients were prospectively enrolled in this study. All of the patients were between the ages of 1 month and 12 years and were undergoing elective neurosurgical procedures. The 91 patients who completed the protocol received a bilateral lower-extremity Doppler ultrasound examination within 48 hours prior to surgery. Patients did not receive either medical or mechanical DVT prophylaxis during or after surgery. The ultrasound examination was repeated within 72 hours after surgery. An independent, board-certified radiologist evaluated all sonograms. We prospectively collected data, including potential risk factors, details of surgery, and details of the clinical course. All patients were followed clinically for at least 1 year.RESULTSThere was no clinical or ultrasound evidence of DVT or VTE in any of the 91 patients. There was no clinical evidence of VTE in the 9 patients who did not complete the protocol.CONCLUSIONSIn this prospective study, no DVTs were found in 91 patients evaluated by ultrasound and 9 patients followed clinically. While the study is underpowered to give a definitive incidence, the data suggest that the risk of DVT and VTE is very low in children undergoing elective neurosurgical procedures. Prophylactic protocols designed for adults may not apply to pediatric patients.Clinical trial registration no.: NCT02037607 (clinicaltrials.gov)
