Spontaneous chylopericardium in an adult due to mediastinal cystic hygroma

Chylopericardium is a rare and benign condition. Apart from common causes like non-surgical trauma, tuberculosis, malignancy, radiation, and postoperative, mediastinal cystic hygroma presenting as chylopericardium is an extremely rare entity. Primary or idiopathic chylopericardium is diagnosed when the precise cause is not known. It is a diagnosis of exclusion. We report a 27-year-old lady with mediastinal cystic hygroma, presenting as spontaneous chylopericardium, who was managed surgically with no recurrence on 18 months follow-up. She was evaluated for complaints of discomfort in the upper abdomen region and breathing difficulty in left lateral position for 4 days, and was found to have a large pericardial effusion with impending tamponade. She underwent pericardiocentesis, and on fluid analysis, it was confirmed as chylous pericardial effusion. She was evaluated thoroughly and was taken up for right video-assisted thoracoscopy. The thoracic duct was clipped and a window was created in the pericardium, the cystic hygroma was excised, and pleurodesis was done. The postoperative period was uneventful. Histopathology of the pericardial window showed chronic inflammatory pathology and cystic lesion was confirmed as a chylous cyst.     

Video-assisted thoracoscopic surgery for primary chylopericardium after orthotopic heart transplantation.

Chylopericardium is a rare complication of cardiac surgical procedures. We describe a 41-year-old woman who underwent orthotopic heart transplantation and developed chylopericardium early in the post-operative period. Because of unsuccessful conservative treatment (pericardiocentesis, pericardial drainage, low-fat diet with medium-chain triglycerides, and total parenteral nutrition), surgical intervention was indicated and the patient successfully underwent right-sided thoracoscopic duct ligation and partial pericardiectomy (pericardial window).     

Subxiphoid pericardial window for pericardial effusive disease

A subxiphoid pericardial window made in 123 patients allowed drainage and diagnosis of pericardial effusions. In 40 patients with malignancy and effusions, median drainage was 450 ml; cytology was positive in 17 or 36 (47%), and pericardial biopsy showed cancer in 13 (43%) of 30 patients. In 11 patients with malignancy, both cytology of effusions and biopsy of the pericardium were negative. In 83 patients with benign effusions, median drainage was 400 ml. Effusions recurred in 14 of the 123 patients (11%); nine patients in the benign group and five in the malignant group. Five of these 14 underwent thoracotomy (3 to 542 days postoperatively); two underwent median sternotomy and one underwent pericardiocentesis. Two intraoperative deaths resulted from cardiac arrest. Mortality at 30 days was 25% (10/40 patients) in the malignant group and 11% (9/83 patients) in the benign group. No deaths resulted from recurrent effusions. The establishment of a subxiphoid pericardial window allows rapid and safe drainage of pericardial effusions with sampling for cytology and pericardial biopsy. It has minimal morbidity and few recurrent effusions.     

Cardiac tamponade following penetrating mediastinal injuries: improved survival with early pericardiocentesis.

Cardiac tamponade was diagnosed in 197 patients admitted over 20 years (1955-1974) to the Charity Hospital of New Orleans, for emergency treatment of pentrating mediastinal injuries. Of the 197, 174 definitively treated patients followed one of three patterns of management: 96 had OR thoracotomy, 68% were unstable, and preoperative pericardiocentesis reduced mortality from 25 to 11% (p less than 0.01); 44 had emergency thoracotomy, 91% were unstable, and prethoractomy pericardiocentesis decreased mortality from 94 to 63% (p less than 0.05); 34 patients primarily with isolated stab wounds, were treated nonsurgically with pericardiocentesis and observation, only 50% were unstable and there was 15% mortality. Recurrent tamponade did not significantly increase overall or operative mortality in patients with pericardiocentesis. Recommendations: early, even presumptive, diagnosis of tamponade; immediate pericardial decompression via pericardiocentesis; and rapid transfer to OR for thoracotomy or sternotomy and cardiorrhaphy with continous pericardial decompression via intrapericardial catheter.     

Massive primary chylopericardium: a case report

A large pericardial effusion was discovered in an asymptomatic 12-year-old boy admitted for an elective orthopedic procedure. On physical examination, heart rate was 96 and blood pressure was 130/70 without paradox. The neck veins were not distended, but heart tones were distant. Chest roentgenogram (CXR) showed an enlarged cardiac silhouette. Echocardiogram showed a massive pericardial effusion compressing the right atrium, with depressed ventricular contractility. Pericardiocentesis yielded 450 mL of chylous fluid. A percutaneous pericardial drain was placed and drained another 400 mL of chyle. Pericardial fluid reaccumulated even though the patient was on a low-fat diet, and 1 week after admission left thoracotomy was performed with partial pericardiectomy and pericardial window. There was 1 L of chyle in the pericardial sac; frozen section of the pericardium showed lymphangiectasia. Chest tube drainage diminished rapidly and the patient was discharged. Follow-up CXR at 1 week showed fluid in both pleural spaces requiring bilateral tube thoracostomies again draining chyle. Even with total parenteral nutrition (TPN), 500 mL/d of chyle drained from the pleural tubes. Right thoracotomy with ligation of the thoracic duct was performed after 1 week of TPN. Pleural drainage abruptly dropped, and there has been no reaccumulation in either the pleural spaces or pericardium at 6-month follow-up. This case dramatically supports early thoracic duct ligation and partial pericardiectomy as the treatment of choice for primary massive chylopericardium.     

Chylopericardium after cardiac operations in children

BACKGROUND: Chylopericardium is a rare complication after operation for congenital heart disease. The incidence and clinical outcomes in a large cohort of surgical patients are unknown. METHODS: We retrospectively reviewed the clinical records spanning more than 12 years in a single institution of 16 children with chylopericardium after cardiac operation. RESULTS: We identified 16 patients with chylopericardium between 1985 and 1997. Chylopericardium was isolated in 7 patients. Twelve patients required pericardial drainage. Patients with isolated chylopericardium presented late and were treated initially as having postpericardiotomy syndrome. Three patients underwent thoracic duct ligation. There were two late deaths unrelated to the chylothorax. Associated diagnoses were internal jugular vein thrombosis and recurrent pulmonary vein obstruction (1 of 16 patients), an associated syndrome but not Turner or Noonan (10 of 16), superior cavopulmonary or total cavopulmonary anastomosis (7 of 16), atrioventricular septal defect repair (5 of 16), and repair of tetralogy of Fallot (2 of 16). CONCLUSIONS: Percutaneous drainage to relieve tamponade together with a low-fat or medium-chain triglyceride diet results in resolution in most cases of postoperative chylopericardium. If a pericardial effusion enlarges, fails to clear on aspirin therapy, or presents late after hospital discharge, diagnostic pericardial tap and a low-fat diet are indicated.     

Uremic pericardial effusion. Treatment by catheter drainage and local nonabsorbable steroid administration.

Pericardial drainage via percutaneous catheter placement and local nonabsorbable steroid instillation was employed as definitive therapy for uremic patients who had intractable pericardial effusions. Twelve patients are reported. Prior daily dialysis, and in one case systemic steroids, were not curative. 11 of 12 cases suffered severe tamponade requiring pericardiocentesis. One patient had an organized pericardial effusion, making pericardiocentesis impossible. He required pericardiectomy with prolonged hospitalization (2 weeks) due to postoperative complications. There were no complications in the 11 patients where catheter drainage and local steroid instillation were employed. No patient had recurrence of his pericardial effusion (followed from 2 weeks to 32 months). Instillation of a relatively nonabsorbable steroid through an indwelling pericardial catheter provides immediate and lasting relief without either the inconvenience or postoperative complications and prolonged hospitalization associated with the surgical procedure of pericardial fenestration. This report offers initial evidence that the percutaneous approach may be a safe and effective alternative to pericardial fenestration in most uremic patients with pericardial effusion.     

Late cardiac tamponade after open heart surgery

Delayed cardiac tamponade after open heart surgery is relatively uncommon, but constitutes a life-threatening condition that must be diagnosed and managed promptly. We report 21 patients who developed cardiac tamponade 5 to 53 days after open heart operations. Possible etiological factors included anticoagulant therapy (19 patients), excessive mediastinal drainage in the postoperative period (10 patients), postpericardiotomy syndrome (4 patients), and coagulation disorders (1 patient). The clinical presentation was insidious and the diagnosis was often difficult to establish at the outset. A high index of clinical suspicion and echocardiography were the most reliable means to reach an early diagnosis. Twenty patients in whom delayed tamponade was suspected were operated and all of them survived. In one patient tamponade was not diagnosed antemortem and he died; on autopsy left heart compression by a large loculated clot was found. Decompression of the pericardial space can be accomplished by pericardiocentesis or by surgical means (subxiphoid pericardiotomy, median sternotomy, or thoracotomy). Although pericardiocentesis alone may be effective, mainly when the postpericardiotomy syndrome is the suspected etiology, we recommend open procedures since the presence of blood clots and adhesions has been a frequent finding.     

Left ventricular pseudoaneurysm after pericardiocentesis

We present the case of a patient with recurrent episodes of pericardial effusion and fever. During approximately one month, the patient was treated with double pericardiocentesis for cardiac tamponade and the last of them was interrupted for the suspect of left ventricular puncture due to aspiration of arterial blood from the needle used for pericardiocentesis. Considering the suspect of infective pleuro-pericarditis and patient's symptoms, a surgical drainage of the pericardial effusion was performed via right thoracotomy. The echocardiography and CT-scan performed after right thoracotomy showed only a mild pericardial effusion. Fifteen days later, the patient suffered from congestive heart failure and fever. The echocardiography and CT-scanning which were performed urgently, showed a large pseudoaneurysm (approx. 26 mm x 36 mm) of the apex of the left ventricle. Ventriculography confirmed the presence of the pseudoaneurysm in connection with the left ventricular apex. Exclusion of the LV pseudoaneurysm was performed using a Prolene 0 running suture on two strips of bovine pericardium, avoiding ECC use. The patient was discharged on the 7th postoperative day. Iatrogenic pseudoaneurysm caused by pericardiocentesis represents a very rare complication and it should be prevented by identifying the high-risk patients.     

Chylopericardium Secondary to Lymphangiomyoma - A case report -

Chylopericardium is a rare disease entity characterized by the accumulation of chylous fluid in the pericardial sac. It usually arises from mediastinal neoplasms, thrombosis of the subclavian vein, tuberculosis, nonsurgical trauma, thoracic or cardiac surgery. The spectrum of symptoms for chylopericardium varies from an incidental finding of cardiomegaly to dyspnea, upper abdominal discomfort, cough, chest pain, palpitation, fatigue. However, most of the patients are asymptomatic. The main purpose of treatment of chylopericardium is the prevention of cardiac tamponade and prevention of metabolic, nutritional, and immunological compromise due to chyle leak. Here, we report a case of chylopercardium secondary to lymphangiomyoma with review of the literature.     

Delayed pericardial effusion following stab wounds to the chest.

INTRODUCTION: Delayed pericardial effusion following penetrating cardiac trauma has not been commonly reported, and the exact incidence remains unknown. It was more common before 1960, when pericardiocentesis was still a popular treatment for stable patients presenting with a stab wound to the heart. MATERIAL AND METHODS: During an 8-year period, 24 patients were diagnosed with delayed pericardial effusions following a recent stab wound over the chest. Nine patients had been initially treated at our trauma unit, and the remaining 15 patients were referred by a peripheral clinic. RESULTS: Diagnosis was confirmed by cardiac ultrasound or echocardiogram. Sixteen patients were adequately treated by subxiphoid drainage. Sternotomy was performed in five patients, left thoracotomy in two and right thoracotomy in one patient. No actively bleeding injuries were found. Three patients had active infection in the pericardial space. Fever, pleural effusions and ascites were common associated findings. Additional procedures performed included laparotomy for acute abdominal pain in two patients (both negative), and simultaneous drainage of a pleural empyema. Two patients with staphylococcal pericardial infections required subsequent pericardiectomy. SUMMARY: The diagnosis of a penetrating cardiac patient may be missed in a stable patient, and patients may present with delayed pericardial effusions and tamponade. Post pericardiotomy syndrome may be the most common cause of delayed pericardial effusion, followed by sepsis. Subxiphoid pericardial window is an adequate form of treatment. Recent literature reveals that occult cardiac injury is not uncommon, thus a case should be made to actively investigate all patients with precordial stab wounds with cardiac ultrasound or echocardiogram.     

Pericardial drainage prior to operation contributes to surgical repair of traumatic cardiac injury

We report on two cases of successful surgical repair of cardiac injury: one involving a left ventricular stab injury and the other a blunt rupture of the right atrium. Each patient underwent emergency surgical repair, the former via left anterolateral thoracotomy and the latter via median sternotomy, following pericardial drainage tube insertion from the subxiphoid area. The operative approach was chosen according to the color of drained blood, i.e., arterial bleeding indicated left anterolateral thoracotomy, while venous bleeding indicated median sternotomy. We conclude that pericardial drainage via the subxiphoid approach prior to induction of anesthesia is an easy and useful technique to perform, not only to release cardiac tamponade but to determine the operative approach in patients suffering from cardiac tamponade following cardiac injury.

Clinical experience with subxiphoid drainage of pericardial effusions

To assess the effectiveness of subxiphoid pericardial tube drainage for treatment of pericardial effusion, we reviewed 41 consecutive patients who underwent this procedure during a 14-year period. The patients ranged in age from 7 months to 75 years. All were symptomatic preoperatively. The diagnosis of pericardial effusion was confirmed by echocardiogram in all but 2 patients. Eight patients had acute pericardial tamponade. Subxiphoid pericardial drainage was performed under general (n = 35) or local anesthesia (n = 6). A portion of the anterior pericardium was excised in each patient. There were no perioperative deaths. Thirty-day mortality was 19.5%; there were five late deaths. All deaths were unrelated to pericardial effusion or to the operation. One patient had recurrent effusion requiring pericardiocentesis on the 21st postoperative day. He died five days later of extensive lymphoma. Twenty-eight patients were followed from 1 month to 10 years; mean follow-up was 31.5 months. None developed recurrent effusion or pericardial constriction. We conclude that subxiphoid pericardial drainage is effective for treatment of pericardial effusion.     

Which treatment in pericardial effusion?

BACKGROUND: Pericardiocentesis, pleuro-pericardial window, subxiphoid pericardial drainage and pericardioscopy: which methodology to treat pericardial effusion? Each of these surgical treatments can be effective, depending on clinical factors and history of the patients. We considered pericardial effusions during 5 years. METHODS: We reviewed 64 cases: 14 acute pericardial effusions (5 patients with cardiac tamponade), 39 subacute, 11 chronic. Epidemiology and aetiology: 8 cases were between 20 and 25 years old (all affected by lymphoma), 56 were distributed in every age, especially over 60, and of these 45 were neoplastic and 11 non- neoplastic. Non-neoplastic cases were connectivitis (3 patients), uncertain origin effusion (7 patients), tubercular (1 patient). In neoplastic effusions we found lymphoma (at older age) in 7, small cell lung cancer in 6, NSCLC in 12, mesothelioma in 2, breast cancer in 7. RESULTS: Acute pericardial effusions with cardiac tamponade underwent echo-guided pericardiocentesis. In 43 we had a subxiphoid pericardial drainage, among these cases we performed 4 pericardioscopies. We created a pleuro-pericardial window on VATS in 13, on thoracotomy in 4 for technical reasons. CONCLUSIONS: Pericardiocentesis is to be preferred in acute pericardial effusion with cardiac tamponade to avoid general anaesthesia. Pleuro-pericardial window on VATS is better in chronic pericardial effusion (for infective or systemic disease) and in recurrence, after performing subxiphoid drainage. Subxiphoid drainage is suitable for all neoplastic patients, and in case of unknown aetiology in order to perform a pericardioscopy.

Diagnosis and Management of Postoperative Pericardial Effusions and Late Cardiac Tamponade Following Open-Heart Surgery

The clinical and laboratory findings of 28 patients identified as having late pericardial effusions were examined. Eleven of these patients were asymptomatic; 9 patients had moderate symptoms including fatigue, malaise, weight gain, and dyspnea on exertion, and 8 patients with similar symptoms had evidence of cardiac tamponade. Ten patients underwent right heart catheterization in the intensive care unit; normal hemodynamics were confirmed in 4 and cardiac tamponade in 6 patients. Pericardiocentesis was effective in decompressing cardiac tamponade in 7 of 8 patients. One patient required operative subxiphoid drainage after unsuccessful pericardiocentesis. In addition, 5 patients with moderate clinical symptoms and pericardial effusions, who did not have cardiac tamponade, underwent pericardiocentesis because of a need for chronic anticoagulant therapy. The remaining patients were managed successfully by observation, discontinuation of warfarin when possible, fluid restriction, and diuretic therapy. All but 1 patient was symptomatically improved. A diagnostic and therapeutic schema is presented as an aid to early recognition of this troublesome and potentially lethal complication.     

Abdominal cavity unidirectional shunt for refractory pericardial effusion 7 months after cardiac valve replacement: A case report

Refractory pericardial effusion after repeated pericardial drainage and drug therapy for nearly half a year after cardiac valve replacement is rare. We present the case of a 36‐year‐old female patient who underwent an abdominal cavity unidirectional shunt for refractory massive pericardial effusion through a subxiphoid mini‐incision, 7 months after cardiac valve replacement. The head end of a prefabricated bovine pericardial short tube with double leaflets on the tail was sutured to the small incised hole of the diaphragm, whereas the body and the tail of the short tube were dissociated in the left anterior hepatic space. Three months later, the pericardial effusion completely disappeared, no peritoneal effusion occurred, and all symptoms vanished.

Pleuroperitoneal shunts in the management of persistent chylothorax

Between June 1981 and June 1988, we placed pleuroperitoneal shunts in 16 patients for the management of refractory chylothorax on the Pediatric Surgical Service, University of Virginia. The cause of the chylothorax was caval thrombosis from central venous catheters in 5 patients, idiopathic in 3, and mediastinal lymphangioma in 2, and in 6, it developed after a cardiac procedure. Chylothorax in each patient was unresponsive to thoracentesis, tube thoracostomy, and dietary manipulations. A Denver double-valved shunt system is currently employed and is implanted using general anesthesia. Manual pumping is required postoperatively for several months. Twelve (75%) of the 16 patients had excellent results with complete elimination of the chylothorax and resolution of symptoms. In 10 of these 12, the shunt has been removed. Four had an unsatisfactory result: 3 had inferior vena cava hypertension, and 3 were low-birth-weight premature infants. Four patients seen early in this series required revision of the position of the pleural catheter, with successful drainage in each instance. Pleuroperitoneal shunting is a safe, simple, and effective treatment of chylothorax in infants and children. In view of our success in treating chylothorax with these shunts, we recommend early shunting before the development of nutritional or immunological depletion.
