Temporal changes in deep venous thrombosis risk after electrical injury

Previous work has used the National Burn Repository to examine deep venous thrombosis (DVT) after electrical injury. However, these studies were limited and could not examine when DVT occurs after electrical injury. In addition, the utility of risk assessment models for DVT risk stratification has not been examined in this patient population. The authors performed a retrospective chart review of electrically injured patients at a single, American Burn Association- and American College of Surgeons-verified burn center over a 9-year period. Risk factors were identified and used to calculate Caprini scores at baseline and time of discharge. Outcomes of interest included symptomatic DVT or pulmonary embolism and time to DVT or pulmonary embolism. A total of 77 electrically injured patients were identified. DVT incidence was 6.5%. Patients with DVT had significantly higher TBSA (27.8% vs 3.8%), mean number of operations (4.8 vs 0.3), central venous catheter insertion (100% vs 5.3%), ventilator days (16.2 vs 0.3), intensive care unit days (24.4 vs 0.9), and mean change in Caprini score (18.6 vs 1.3) during hospitalization. Baseline Caprini scores were low, and DVT events occurred only after multiple risk factors were present; the average time-to-event was hospital day 17. Among patients with Caprini score >8, DVT incidence increased to 62%. In our single-center experience, the Caprini score was able to quantify DVT risk after electrical injury. In our series of 77 patients, the overall incidence of DVT was 6.5%. However, among patients whose Caprini score reached >8 during hospitalization, DVT incidence increased to 62%.

Early fasciotomy in electrically injured patients as a marker for injury severity and deep venous thrombosis risk: an analysis of the National Burn Repository

By using the National Burn Repository, the authors sought to identify markers for injury severity and deep venous thrombosis (DVT) risk after electrical injury. They identified adult patients in the National Burn Repository who were admitted with an electrical injury between 1995 and 2007 (n = 1469). Patients who died within 24 hours or were admitted for less than 1 day and hospitals reporting no complications were excluded. Independent variables included TBSA burned, duration of intensive care unit stay and hospital admission, duration of mechanical ventilation, the number of operative procedures, amputation, and early fasciotomy. Early fasciotomy was defined as fasciotomy performed on a patient's first trip to the operating room and was used as a proxy for severity of electrical injury. DVT and death were the dependent variables. Among electrically injured patients, 10.4% had early fasciotomy. Patients who had early fasciotomy had significantly prolonged intensive care unit stays (10.3 vs 4.8 days, P < .001), hospital days (36.7 vs 17.1 days, P < .001), amputations (49.0 vs 4.6%, P < .001), and a number of operative codes (17.6 vs 5.4, P < .001). DVT incidence was 0.9%. Electrically injured patients who had early fasciotomy were significantly more likely to have a DVT when compared with patients who did not have early fasciotomy (7.55 vs 0.95%, P = .002). Early fasciotomy after electrical injury is a marker for increased injury severity. Among patients who underwent early fasciotomy after electrical injury, 7.5% develop DVT, and 49% require amputation during their initial hospitalization.

Mondor's disease

Mondor's disease (MD) is a rare condition, which is considered a thrombophlebitis of the subcutaneous veins. It commonly occurs on the anterolateral thoracoabdominal wall, but it can also occur on the penis, groin, antecubital fossa and posterior cervical region. The clinical features are a sudden and typically asymptomatic onset of a cord-like induration, although some patients report a feeling of 'strain'. It is a self-limiting process that lasts a short period of time, which may be the reason why there are few reports about its diagnosis and treatment. Its pathogenesis has remained unclear, because of the lack of methods to reliably differentiate between veins and lymphatic vessels. Immunohistochemical staining for CD31 and D240 has been identified recently as the best method to distinguish small veins from lymphatic vessels, making it a valuable technique in diagnosing not only MD, but also many other diseases in which veins or lymphatic vessels are affected. MD has been associated with several systemic diseases such as breast cancer and hypercoagulability states, thus laboratory studies are recommended to exclude any possible systemic disorders. As this condition is usually a benign and self-limiting process, vigorous treatment is only recommended when the process is symptomatic or recurrent.
