Penetrating cardiothoracic war wounds

OBJECTIVE Penetrating cardiothoracic war wounds are very common among war casualties. Those injuries require prompt and specific treatment in an aim to decrease mortality and late morbidity. There are a few controversies about the best modality of treatment for such injuries, and there are not many large series of such patients in recent literature. METHODS We analysed a group of 259 patients with penetrating cardiothoracic war wounds admitted to our institutions between May 1991 and October 1992. RESULTS There were 235 (90.7%) patients with thoracic wounds, 14 (5.4%) patients with cardiac, wounds and in 10 (3.7%) patients both heart and lungs were injured. The cause of injury was shrapnel in 174 patients (67%), bullets in 25 patients (9.7%), cluster bomb particles in 45 patients (17.3%) and other (blast etc.) in 15 patients (6%). Patients, 69, had concomitant injuries of various organs. The initial treatment in 164 operated patients was chest drainage in 76 (46.3%) patients, thoracotomy and suture of the lung in 71 (43.2%) patients, lobectomy in 12 (7.3%) patients and pneumonectomy in 5 (3%) patients. Complications include pleural empyema and/or lung abscess in 20 patients (8.4%), incomplete reexpansion of the lung in 10 patients (4.2%), osteomyelitis of the rib in 5 patients (2.1%) and bronchopleural fistula in 1 patient (0.4%). Secondary procedures were decortication in 12 patients, rib resection in 5 patients, lobectomy in 2 patients, pneumonectomy in 4 patients, reconstruction of the chest wall in 2 patients and closure of the bronchopleural fistula in 1 patient. The cardiac chamber involved was right ventricle in 12 patients, left ventricular in 6 patients, right atrium in 7 patients, left atrium in 3 patients, ascending aorta in 2 patients and 1 patient which involved descending aorta, right ventricle and coronary artery (left anterior descending) and inferior vena cava, respectively. The primary procedure was suture in 17 patients (in 10 patients with the additional suture of the lung), suture + extraction of the foreign body in 4 patients, 2 of them with cardiopulmonary bypass. Complications were pericardial effusion in 6 patients, arrhythmia in 2 patients, myocardial infraction in 1 patient and migration of the foreign body in 1 patient. Patients, 7, died, five of the group with concomitant injuries, two of thoracic and one of cardiac injuries (5, 1.2 and 4.2%, respectively). CONCLUSIONS Penetrating cardiothoracic wounds are among the most serious injuries in war, either in combat or among civilians. In spite of their nature, they can be treated successfully with relatively low mortality and morbidity.

Stable gastric pentadecapeptide BPC 157 in trials for inflammatory bowel disease (PL-10, PLD-116, PL14736, Pliva, Croatia) heals ileoileal anastomosis in the rat.

PurposeGastric pentadecapeptide BPC 157 (BPC 157), which has been shown to be safe in clinical trials for inflammatory bowel disease (PL-10, PLD-116, PL14736, Pliva, Croatia), may be able to cure intestinal anastomosis dehiscence. This antiulcer peptide shows no toxicity, is limit test negative, and a lethal dose is not achieved. It is stable in human gastric juice. In comparison with other standard treatments it is more effective for ulcers and various wounds, and can be used without a carrier needed for other peptides, both locally and systemically (i.e., perorally, parenterally). We studied the effectiveness of BPC 157 for ileoileal anastomosis healing in rats.MethodsWe assessed ileoileal anastomosis dehiscence macroscopically, histologically, and biomechanically (volume [ml] infused through a syringe-perfusion pump system (1 ml/10 s), and pressure [mmHg] to leak induction [catheter connected to a chamber and a monitor, at 10 cm proximal to anastomosis]), at 1, 2, 3, 4, 5, 6, 7, and 14 days. BPC 157 (10 µg, 10 ng, 10 pg/kg i.p. (or saline [5 ml/kg]) was first administered after surgery, while it was last given 24 h before either assessment or sacrifice.ResultsThroughout the experiment, both higher doses of BPC 157 were shown to improve all parameters of anastomotic wound healing. The formation of adhesions remained slight, the blood vessels were filled with blood, and a mild intestinal passage obstruction was only temporarily observed. Anastomosis without leakage induces markedly higher volume and pressure values, with a continuous increase toward healthy values. From day 1, edema was markedly attenuated and the number of granulocytes decreased, while from days 4 or 5 necrosis decreased and granulation tissue, reticulin, and collagen formation substantially increased, thus resulting in increased epithelization.ConclusionThis study showed BPC 157 to have a beneficial effect on ileoileal anastomosis healing in the rat.

NT-pro-BNP, but not C-reactive protein, is predictive of atrial fibrillation in patients undergoing coronary artery bypass surgery

OBJECTIVE Atrial fibrillation (AF) remains the most commonly observed complication following myocardial revascularisation surgery. We aimed to evaluate the clinical utility of N-terminal fragment of the brain natriuretic peptide (NT-pro-BNP), troponin T, transcoronary lactate gradient (TCLG) and C-reactive protein (CRP) as predictors of AF in patients undergoing isolated coronary artery bypass surgery (CABG). METHODS This study included 215 consecutive patients in sinus rhythm (SR) undergoing elective CABG between May 2007 and May 2008. The patients were grouped according to their respective postoperative rhythm into SR and AF groups. The data are presented as mean values+/-standard deviation, or medians with quartiles. RESULTS Fifty-five patients developed AF (26%). The preoperative NT-pro-BNP values were 273+/-347 and 469+/-629 pg ml(-1) in the SR and AF groups, respectively (p<0.0001). The postoperative NT-pro-BNP values were 3110+/-3600 pg ml(-1) in the SR and 4625+/-5640 pg ml(-1) in the AF groups (p=0.027). The transcoronary lactate gradient rose from the pre-cardiopulmonary bypass values to those observed 5 min after revascularisation in both groups (-0.05+/-0.37 to 0.39+/-0.46 mmol l(-1) (p<0.0001) in the SR group and -0.01+/-0.27 to 0.43+/-0.46 mmol l(-1) (p<0.0001) in the AF group). The CRP values increased from 6+/-13 to 163+/-88 mg l(-1) (p<0.0001) in the SR group, and from 6+/-16 to 163+/-104 mg l(-1) (p<0.0001) in the AF group. The dynamics of TCLG and CRP did not differ between the groups (p=0.71, p=0.44, respectively). The troponin T values on postoperative day 1 were significantly higher in the AF than the SR group (0.86 (0.49-2.1) ng ml(-1) vs 0.67 (0.37-1.16) ng ml(-1), p=0.046). The duration of cardiopulmonary bypass (CPB) was 85+/-24 min in the SR and 93+/-30 min in the AF group (p=0.05). Patients who developed AF were older (66+/-7 years vs 60+/-9 years, p<0.0001) and had a higher EuroSCORE (3.9+/-2.7 vs 2.9+/-2.2, p=0.009). Multivariate analysis identified age (p=0.0043), preoperative NT-pro-BNP (p=0.019) and duration of CPB (p=0.035) as independent predictors of AF. CONCLUSIONS Preoperative and postoperative NT-pro-BNP as well as TnT values were significantly higher in patients who subsequently developed AF. TCLG and CRP were not useful in identifying patients at higher risk for AF. Multivariate analysis identified age, preoperative NT-pro-BNP and duration of CPB as independent correlates of AF.

Primary malignant fibrous histiocytoma of the heart with skeletal muscles metastases.

Abstract  Malignant fibrous histiocytoma is an extremely rare primary malignant tumor of the heart. It is usually diagnosed when it is locally aggressive or has already metastasized. The prognosis is poor with an average survival time of one year. We report a case of recurrent left atrial malignant fibrous histiocytoma initially misdiagnosed as myxoma. The patient underwent repeated surgical resections followed by chemotherapy. Despite adjuvant chemotherapy, 18 months after initial diagnosis, definitive tumor relapse in left atrium was diagnosed. This is the 48th case of primary cardiac fibrous malignant histiocytoma reported in the literature.

Intracardiac shrapnel in a polytraumatized child

Penetrating cardiac trauma is a life-threatening condition and presents a therapeutic challenge for the surgeon. Additional multiple organ-system injuries, as are common in the setting of war, further complicate the management of such patients. We present the case of a 9-year-old girl who sustained multiple injuries from an unexploded artillery shell, resulting in a retained intracardiac shrapnel. Her cardiac pathology consisted of a shrapnel located in the interventricular septum accompanied by a pneumopericardium and a right-sided hemopneumothorax. The presentation and management of this patient are the subjects of this report.

Aetiology and outcome of acute renal failure secondary to war related trauma and infectious disease in Croatia

Summary: The aim of our study was to explore the aetiology and the outcome of acute renal failure (ARF) during the war in Croatia. of the 2132 patients admitted to our hospital between April 1990 and November 1992 due to war related trauma, 11 (0.5%) developed ARF. We believe that the development of ARF in these patients was secondary to an overwhelming septic process. Most of our patients suffered from multiple organ failure. of the 11 patients suffering from ARF due to war related trauma only four recovered (63.6% had died). We attribute the lethal outcome to the progression of the septic process. Patients who developed ARF due to infectious diseases unrelated to trauma had a different prognosis. Acute renal failure caused by the Hantan virus ran a benign course, in both its oliguric and non‐oliguric form. Patients who developed ARF as a complication of leptospirosis also had a good prognosis. Although ARF is usually of a multifactorial genesis, our study aimed to emphasize the importance of disseminated septic processes as a cause of ARF.

Surgical excision of a hemangioendothelioma of the left ventricle

Primary intracardiac neoplasms are most commonly histologically benign with only 30% exhibiting signs of malignancy. Metastatic tumors of the heart are 30 times more common than primary cardiac tumors. Patients with intracardiac masses may present with dyspnea on exertion, thromboembolic events, pericarditis, arrhythmias, or congestive heart failure. In many, however, the diagnosis is made upon discovering a murmur in an otherwise asymptomatic patient. Hemangioendotheliomas are very rare tumors of the heart characterized by capillary-sized vessels lined by rounded and often multilayered endothelial cells. Cardiac muscle cells are found compressed between proliferating vascular channels. We present a patient with this unusual cardiac tumor with no previous cardiac history and a new systolic murmur.
