[A report of 4 cases of aortic operation using open proximal anastomosis under the hypothermic circulatory arrest and left lateral exposure].

Four cases of aortic operations using open proximal anastomosis (OPA) under the hypothermic circulatory arrest (HCA) and left lateral approach (LLA) are reported. Three of 4 cases had extensive aortic disease from distal arch to descending thoracic aorta (Stanford type B chronic aortic dissection, double false aneurysms, and double true aneurysms). Another one case had ruptured aneurysm of thoracic aorta. LLA should have been selected in all cases, however, aortic proximal cross-clamp was impossible in them, because of giant pseudolumen, diseased lesion of aortic arch, hemothorax followed rupture of aneurysm. Therefore OPA under the HCA was performed. There were no complication associated with HCA, bleeding, neurological deficiency and respiratory dysfunction. We conclude that, although the HCA may have some problems, if there is the proper indication, OPA under the HCA is useful method at aortic operation for difficult aortic disease.

[Gunshot wounds of the abdomen studied by computed tomography. The authors' personal experience in 30 cases].

INTRODUCTION: CT plays an important role in depicting gunshot wounds in parenchymal and hollow organs in the abdomen. Relative to other techniques and to emergency laparotomy, CT permits good assessment of abdominal content, major injuries and changes in other districts, such as chest, pelvis and skull. We investigated the yield and role of CT in diagnosing abdominal gunshot wounds, with their rich and varied radiological signs and associated injuries. MATERIAL AND METHODS: We retrospectively reviewed the findings of 30 patients with abdominal gunshot wounds examined in 4 years at Loreto-Mare Hospital, Naples. All patients were men, age ranging 19-54 years (mean: 35); 6 of them were not from the European Union. Examinations were carried out from diaphragm to pubis with i.v. contrast injection and the CT angiography technique. CT was integrated with chest studies in 6 cases and with skull studies in 5. Subsequent CT follow-ups were necessary in 12 cases submitted to conservative treatment. RESULTS: Liver was the most damaged parenchyma, with hemorrhage and lacerocontusion in 7 cases and mashed in 1 case; spleen was involved in 4 cases; hemoperitoneum was found in 18 cases. Diaphragm was involved in 5 cases and pancreas in 2; gallbladder, stomach and duodenum were involved in 1 case each and jejunum-ileum and colon in 3 and 6 cases, respectively. CT showed renal injury in 3 cases and bladder injury in 2. Eight patients had vertebral gunshot damage. Pneumothorax, hemothorax and lacerocontusion were found in 7 cases; brain was injured in 4 cases and limbs in 16. DISCUSSION AND CONCLUSIONS: Tissue damage extent depends on the speed and kinetic energy the bullet carries into the abdomen. Abdominal radiography shows the bullet and its site, pneumoperitoneum from gastrointestinal perforation, crash bone injuries, vertebral trauma and subcutaneous emphysema. Instead, CT depicts early parenchymal damage and vascular injury and thus becomes a complete and necessary tool for imaging gunshot wounds. CT provides early diagnostic information which help plan emergency treatment and thus decrease mortality. As for angiography and US, we suggest they be used subsequently because in emergency they may delay the diagnosis. Moreover, vessel rupture and active intraabdominal bleeding are easily detected with spiral CT, which appears the best tool for prompt assessment of the injuries associated with gunshot wounds in other districts such as, the skull. To conclude, CT permits adequate planning of emergency surgery and helps select the cases for follow-up, intensive care and conservative treatment.

Echocardiographically guided pericardiocentesis - the gold standard for the management of pericardial effusion and cardiac tamponade.

BACKGROUND: The conventional surgical pericardiotomy and blind needle-puncture pericardiocentesis using a subxiphoid approach have been reported to have only moderate success rates and to be associated with unacceptably high rates of morbidity and mortality. More recently, echocardiographically guided pericardiocentesis was reported to improve considerably the likelihood of success and the safety of this procedure. OBJECTIVE: To evaluate the efficacy and safety of echocardiographically guided pericardiocentesis in the authors' institution. PATIENTS AND METHODS: A series of consecutive patients who underwent percutaneous pericardiocentesis at the Hamilton General Hospital, Hamilton, Ontario, from June 1994 to December 1998. RESULTS: Forty-one patients underwent a total of 46 echocardiographically guided pericardiocentesis procedures. The procedure was successful in 100% of attempts. Clinical complications occurred in two (5%) patients: one patient with known coagulopathy developed hemothorax and one patient developed purulent pericarditis several days after the procedure. There were no deaths, and no patient required urgent referral for surgical management. CONCLUSIONS: Echocardiographically guided pericardiocentesis is safe and effective, and is the method of choice for therapeutic and diagnostic drainage of pericardial effusions. While echocardiographically guided pericardiocentesis was described originally at centres with large volumes of patients with clinically significant pericardial effusions and with extensive experience in using this technique, similar high success and low complication rates were attained at an institution with relatively low numbers of patients requiring pericardial drainage.

History of surgery for penetrating chest trauma.

The military surgery experience of the past several centuries has been an important determinant of the evolution of the clinical management of penetrating thoracic trauma. The major management problems fall into two main categories: acute, life-threatening conditions such as open pneumothorax and exsanguinating hemorrhage, and chronic conditions such as clotted hemothorax, empyema, and fibrothorax. Better treatment and prevention of the latter has greatly reduced morbidity. Although hospital mortality has fallen by a factor of ten since the middle of the nineteenth century, the total mortality caused by penetrating thoracic trauma has undergone less change.

[Iatrogenic extrapleural hematoma].

We encountered a rare case of complications at the time of central venous catheterization due to extrapleural hematoma. A 71-year-old woman was scheduled to undergo subtotal gastrectomy. After introduction of general anesthesia, a CVP catheter was inserted from the right jugular vein, but it was removed intraoperatively, because of poor dropping of the infusion fluid. A few minutes later, the blood pressure started to decrease. We considered that this symptom was derived from the surgical procedure, and rapid blood transfusion associated with administration of a vasopressor was performed. Postoperative chest X ray revealed poorly delineated right lung field, and hemothorax was suspected. However thoracic drainage resulted in an extremely small amount of blood-like fluid. The abnormal defect in the right pulmonary field was found to be an extrapleural hematoma by thoracic CT on the first postoperative day. The hematoma was reduced by subsequent management in 7 days, and the patient was discharged from the ICU without any further complications.

[The surgical treatment of pulmonary and associated echinococcosis in childhood].

Over a nine-year period (1990-1998), a total of 196 children with pulmonary and associated hydatid disease, aged 2 to 16 years, undergo treatment in the Department of Pediatric Thoracic Surgery--Emergency Medicine Institute "N. I. Pirogov"--Sofia. One hundred thirty children (62.1%) present isolated, and sixty-six (38.8%)--associated hydatid disease, of which with localization in the liver (63 cases), brain (1), kidney (1) and spleen (1). The pulmonary cysts are located in the left lung in 96 cases (48.9%), right lung--79 (40.3%) and bilateral involvement--21 (10.8%). In 74 children the disease runs an asymptomatic course, in 128 (65.3%)--with fever and cough, and in 65 (33.1%)--with thoracic pain. On admission 183 children (94.4%) are in a satisfactory and good general condition; 13 with complications in the cyst and pleural cavity are in a serious general condition accompanied by respiratory failure. In 129 children diagnosis is made on the ground of x-ray study, in 40 CAT study is additionally performed, and in 24--ultrasonography. Of 22 children with bilateral pulmonary location, 13 (59.9%) undergo operation in two stages, and nine (40.1%)--in one stage, with bilateral thoracotomy done in seven, and sternotomy in two instances. Intraoperatively more than one echinococcus cysts are discovered in 23 cases (11.7%). In 105 children (53.5%) echinococcotomy is performed, in 67 (34.2%)--atypical resection, in 8 (4.1%)--lobectomy, in 15 (7.6%)--segmentectomy and in one--pneumonectomy. In the early postoperative period, one child develops hemothorax from a bleeding intercostal artery, and another one--pneumothorax from unsutured bronchus in the cyst bed necessitating emergency re-thoracotomy. The outcome is fatal in one patient with malignant hyperthermia, and the remainder are discharged clinically cured.

[Chylothorax following penetrating injury].

We describe a 19-year-old man with 9 stab wounds of the chest. Initial evaluation revealed paraplegia at the D-10 level and bilateral hemothorax. 2 days after admission right-sided chylothorax was diagnosed. Fasting and total parenteral nutrition resulted in complete clearance. Chylothorax can cause major metabolic consequences, but prompt treatment results in full recovery.

[Perioperative morbimortality in pneumonectomy. Analysis of risk factors].

UNLABELLED: Pneumonectomy continues to be associated with high rates of morbidity and mortality. OBJECTIVE: The aim of this study was to determine the mortality and morbidity rates after pneumonectomy and to analyze perioperative risk factors related to mortality. PATIENTS AND METHODS: The cases of 266 patients undergoing pneumonectomy between January 1986 and December 1997 were reviewed retrospectively: 241 patients with lung cancer, 4 with pulmonary metastasis, 9 with bronchiectasis and 12 with other benign diseases; 13% received neoadjuvant therapy. The bronchial stump was stapled in 92%, sutured in 8%, and covered with autologous tissue in 73%. Intrapericardial pneumonectomy was performed in 32%, pneumonectomy extended to the chest wall or diaphragm in 9%, and completion pneumonectomy was performed in 3%. We collected general demographic data, medical histories, pulmonary function data and surgical technique. Deaths and postoperative complications within the first 30 days after pneumonectomy were also known. RESULTS: Two hundred sixty-six pneumonectomies were performed [right 102 (38%); left 164 (62%)] in 249 men (93%) and 17 women (7%) who were 58 +/- 11 years of age (20 to 79 years). The rate of early postoperative death (30 days) was 5.6%. Mortality rates were higher among patients over 70 years of age (p = 0.045), diabetics (p = 0.038), patients undergoing neoadjuvant therapy (p = 0.031), those with FEV1 under 1,800 ml (p = 0.013), cases of right-sided pneumonectomy (p = 0.001), cases of extended pneumonectomy (p = 0.037) or those without coverage of the bronchial stump (p = 0.005). Mortality was also higher when complications appeared involving the bronchial stump (p < 0.01), heart (p < 0.001), respiration (p < 0.001) or digestion (p = 0.002). Overall morbidity was 40%. Surgical complications developed in 23%: postpneumonectomy empyema (10%), bronchopleural fistula (7%) (with no significant difference related to stapling or suturing), hemothorax (3%) and wound complications (3%). Twelve patients (4.5%) underwent second operations. Cardiac morbidity was 20% (atrial fibrillation in 12%), respiratory morbidity was 8% and other complications appeared in 19% of cases. CONCLUSION: In our experience, mortality after pneumonectomy is 5.6% with an overall complication rate of 40%, mainly due to surgical and cardiac complications. Coverage of the bronchial stump with autologous tissue reduces the risk of postoperative death due to fistula and/or empyema after pneumonectomy.

[Diagnosis and treatment of diaphragm ruptures].

72 cases of diaphragm's ruptures in patients with serious combined trauma illustrated basic methods of diagnosis in this condition including X-ray, ultrasonic methods, computed tomography and thoracoscopy. In 26.3% of the patients the diagnosis was made during laparotomy or thoracotomy for massive bleeding because of injury of other organs. In the absence of bleeding the diagnosis was based on signs of the abdominal organs dislocation into the pleural cavity. The differential diagnosis between right-sided coagulated hemothorax and diaphragm's right cupula ruptures was the most difficult.

Cost-effective approach of video-assisted thoracic surgery: 7 years experience.

BACKGROUND: Cost containment is the driving force behind current health care reform. While video-assisted thoracic surgery (VATS) permits a less invasive approach to surgical diseases of the chest, cost is one aspect that is seldom discussed. In Asia, cost-effectiveness essential for the survival of this approach. We present our cost-effective experience with VATS in 2300 patients over a 7-year period. METHOD: Between 1992 and 1999, 2300 patients underwent video-assisted thoracic surgery at Chang Gung Memorial Hospital. The mean age was 53.2 years (range, 22 days to 102 years); 67% (1541 patients) were men. The VATS technique was mainly performed based on traditional surgical principles. Conventional instruments and the fundamental surgical techniques of dissection, suturing, hemostasis, and tissue approximation that are familiar in the open setting were modified and used to enhance cost savings during VATS. RESULTS: Surgery was performed on 41 patients on an emergency basis (24 with impending cardiac tamponade and 17 with hemothorax). The mean hospital stay of the patients treated by VATS was 4.5 days. The majority of the patients were operated on successfully using conventional instruments under video vision. The overall operative cost was decreased as compared to common VATS techniques. No delayed morbidity was noted in our patients after a mean follow-up period of 39 months (range, 1 to 68 months). CONCLUSION: It is our experience that VATS procedures should be performed with the same expertise as open surgery. Conventional instruments similar to those used in open thoracotomy can be incorporated in VATS, and with a more natural hand manipulation. Only through stringent use of expensive endoscopic consumables and application of modified techniques based on traditional surgical principles can VATS be performed efficaciously and economically for a wide range of thoracic conditions.

[Bronchial stenosis secondary to severe thoracic contusion. Comment on 2 cases].

Two cases with complete bronchial stenosis of the mainstem bronchus secondary to thoracic blunt trauma are presented. One patient had hemoneumothorax on the left side, the other one had bilateral hemothorax. Both were initially treated with drainage by thoracostomy tube with partial resolution of the thoracic bloody pleural collection. Later, the two patients developed complete atelectasis of the lung, one on the left side and the other one in the right; this later case was subject to lung decortication. The fiberopticbronchoscopy showed a complete occlusion of the mainstem bronchus in both patients. A bronchoplasty with sleeve resection of the stenotic segment was performed; the lumen of the bronchus was preserved by an end-to-end suture with separate stitchs of Vycryl 0000. Both cases remain without bronchopulmonary pathology after 4 years of follow-up of bronchoplasty. In cases of blunt thoracic trauma, it is important to consider the possibility of bronchial rupture. The importance of bronchoscopic diagnosis and surgical treatment is stressed.

[A case of tuberculous aneurysm of the aorta].

We reported a rare case of tuberculous aneurysm of the aorta managed successfully with urgent surgical therapy. A 35-year-old woman was admitted to our hospital complaining of fatigue and hemoptysis. Laboratory tests showed severe anemia, slight liver dysfunction, elevated level of C-reactive protein, and negative syphilis serologies. The chest roentgenogram revealed widening of right upper mediastinum, two nodular shadows in right middle lobe, and left-sided infiltration shadow with pleural effusion. The pleural effusion was bloody and its level of adenosine deaminase was normal. Culture of pleural effusion specimen remained negative. A computed tomography scans of the chest revealed an aortic aneurysm on the aortic hiatus. Rapid increase in pleural effusion was followed by hemothorax a few hours later. After operation, she received antituberculosis therapy. Histopathologically, the resected lung showed inflammatory process including granulation of giant cells and epithelioid cells. The specimens of the aortic aneurysm revealed rupture of whole layer of aortic wall and inflammatory cell infiltrations. These findings suggested that the case to be a tuberculous aneurysm of the aorta. Therefore, we diagnosed the case as the rupture of tuberculous aneurysm of the aorta.

[Rapid development of multiple meniscal signs complicating invasive pulmonary aspergillosis in a patient receiving chemotherapy for acute leukemia].

This report describes the rapid development of multiple meniscal signs complicating invasive pulmonary aspergillosis in a 53-year-old man receiving chemotherapy for acute leukemia. While undergoing first induction therapy for AML, he developed chest pain, and multiple bilateral infiltrations were seen in chest roentgenograms. Administration of antibiotics, antifungal agents, steroid pulse therapy and G-CSF was begun. Pulmonary cavities with meniscal signs developed. The next day, pneumothorax and hemothorax were noted. Although drainage and mechanical ventilation were performed, the patient died after massive hemoptysis. Invasive pulmonary aspergillosis was diagnosed at autopsy.

The geriatric puzzle. Assessment challenges of elderly trauma patients.

Assessing elderly patients is like putting together a jigsaw puzzle. In the case described, it's entirely possible that the patient stumbled and fell, bumping his head and bruising his chest. His confusion is probably secondary to dementia, and his vital signs indicate a lack of serious injury. However, it's just as likely that the patient is hypotensive and unable to mount a compensatory tachycardia, has an expanding subdural hematoma, multiple rib fractures with a hemothorax and a ruptured spleen. And it could be worse. His diabetes could be out of control. He could suffer from chronic congestive heart failure, and his living will could be sticking out of his pocket. As the elderly population increases in number, their medical and social issues grow as well. The onus is on us, as healthcare providers, to learn about the aging population and the special problems they present so that we can continue to improve the quality of care we deliver.

Surgical correction of funnel chest.

AIM: To present our experience in surgical treatment of funnel chest. MATERIAL AND METHODS: Seven patients (6 males and 1 female) aged 13 to 18 years were treated in the Department using Rathke-Schlegel's modification of Ravitch operative technique. In 2 patients the corrected deformity status was maintained by 2 Kirschner's pins that were placed substernally and attached bilaterally to the adjacent ribs. In one patient a direct traction through the sternum was applied and in 4 patients the fixation was achieved by fastening the sternum with wire loops to an overlying AO plate. RESULTS: Very good results were achieved in 4 patients (57.14%) and a good outcome was evaluated in 3 patients with 30% recurrence of the deformity. There was no lethal outcome. Three complications were encountered: in one patient hemothorax occurred that was cured by a single punction aspiration, in other patient one of the Kirschner's pins slipped into the thoracic cavity. The pin but did not injure intrathoracic organs and was promptly removed. In the third patient earlier removal of the plate was required because suppuration developed. CONCLUSION: The presented method for correction of chest deformity is successful if the implants are kept in place from 6 to 12 months. This time is sufficient for formation of a solid callus that prevents recurrence of the deformity.

[Traumatic diaphragmatic herniation after continuous thoracic drainage: a case report].

We report a case of traumatic diaphragmatic hernia (TDH) resulting from continuous thoracic drainage and was successfully treated by surgical procedures. A 45-year-old man was admitted to our department due to shock after a blunt trauma by a traffic accident. As he revealed left hemothorax on admission, continuous thoracic drainage was performed. Soon after the drainage, diaphragmatic hernia occurred as an incarceration of the spleen into the thoracic cavity. In the literature, 80 cases with TDH have been reported in Japan since 1986. The purpose of this study is to discuss the mechanism of TDH in the acute phase and to consider its appropriate diagnostic tools. The following two results were obtained. (1) TDH may be appeared during the clinical course, especially after a continuous thoracic drainage, in patients with damaged diaphragm by blunt traumas. (2) CT is the most effective tool for the diagnosis of TDH.

[Epidural anesthesia for a patient with catamenial pneumothorax].

Endometriosis extending into the thoracic cage or the lung might induce defect of the tissue and show catamenial symptoms, such as pneumothorax or hemothorax. These events usually occur 48 to 72 hours after menstruation. A 37-year-old woman with ten year history of recurrent catamenial pneumothorax was scheduled for removal of ovarian cyst. Since intermittent positive pressure ventilation or pneumoperitoneum might induce pneumothorax, we selected epidural anesthesia for laparotomy. Epidural cannulations were performed at Th 9/10 and L 4/5 interspaces. After administration of 2% mepivacaine (400 mg) and fentanyl (0.1 mg), the block extended from Th 6 to S 5. The surgery was done without any complication. In this case epidural anesthesia for laparotomy was useful for the patient with catamenial pneumothorax.

[Liver trauma due to penetrating lesions: miscellanea, personal case series, clinical and CT findings].

PURPOSE: Penetrating liver wounds are related to many causes and rank second after blunt abdominal and liver trauma. We will report the clinical and radiological findings of our personal series of patients with penetrating trauma, especially by firearms and stab and cut wounds. We will also try to define the diagnostic workup of these traumas, which is especially based on CT signs of liver damage and associated changes and which is of basic importance for following treatment, both surgical or conservative. MATERIAL AND METHODS: In the last seven years we retrospectively reviewed 31 cases of penetrating liver trauma. The patients were 19 men and 12 women, ranging in age 18 to 73 (mean 42), with penetrating liver injuries from firearms (16 patients) and stab (9 cases) wounds; 6 patients had injuries from different causes. Abdominal CT was carried out in emergency with the CT Angiography (CTA) technique in all patients. In the patients with suspected chest and abdomen involvement CT was performed from the mid-chest for accurate assessment of diaphragm and lung bases and to exclude associated pleuropulmonary damage. RESULTS: Penetrating liver wounds were caused by firearms in 70% of cases, by stabbing in 12% and, in the extant 18%, by other causes such as home accidents, road and work traumas, and liver biopsy. In our series, the liver was most frequently involved, especially by firearms wounds; in our 16 cases the most frequent injuries were hemorrhagic tears. We found bullets in the liver in 6 cases. In one case of home accident the patient wounded himself while slicing bread with a long knife, which cut into the anterior abdominal wall and tore the anterior liver capsule, as seen at CTA. DISCUSSION AND CONCLUSIONS: Penetrating wounds to liver and abdomen are less frequent than those to the chest. In the past decade the use of CT has changed the diagnostic and therapeutic approach to such injuries completely, decreasing the resort to explorative laparotomy and hepatorrhaphy. Indeed, CT provides a clear picture of the extent and severity of damage, which permits to choose a conservative treatment in case of intraparenchymal hematomas and lacerocontusive foci without hemoperitoneum, which can be followed-up with physical and CT examinations. Moreover, Helical CT could provide the early diagnosis of active bleeding in the peritoneum and of focal bleeding in the liver, thus permitting prompt hepatorrhaphy or targeted hepatectomy. A diaphragm injury suspected at CT should always prompt the surgeon to intervention, especially when hemothorax, lung base pneumothorax, large liver hematoma or tear of the liver dome are associated. Finally, subdiaphragmatic free gas indicates gut perforation associated with liver damage, in which case surgery is necessary too.
