A series of 510 percutaneous infraclavicular subclavian venipunctures performed by the authors is presented. Complications included five cases of simple pneumothorax (0.98%) and one instance of subcutaneous emphysema without pneumothorax (0.20%). No mortality was associated with the procedure.
There have been no published reports of pneumopericardium complicating laparoscopy. Following an apparently uncomplicated laparoscopy, a 35-year-old woman developed pneumopericardium associated with subcutaneous emphysema of the neck. This resolved without specific therapy and without sequelae.
In a 28-year-old woman right-sided pneumothorax developed during a laparoscopic cholecystectomy. The authors believe that the pneumothorax was caused by in the inflow of carbon dioxide into the thoracic cavity without injury to the diaphragm. So far, only a few reports of this complication exist, but in the future it will probably occur more frequently, since the number of laparoscopic operations is increasing. The symptoms are alterations in capnography, subcutaneous emphysema and diminished respiratory sounds.
Steroid therapy increases the risk of bowel perforation. Bowel perforation may occur at any time of steroid therapy, but the first weeks appear to hold the greatest potential for perforation. However, clinical findings after perforation may be misleading under steroids, and peritonitis may be absent. It is known that bowel perforation can lead to subcutaneous emphysema at various sites. Thus, in any patient with emphysema, bowel perforation must be included in the differential diagnosis, especially in patients receiving steroids. Missing knowledge of this entity may lead to marked delay between onset of initial signs and diagnosis, and hence worsen the survival rate. In this report we present a case of chronic steroid use, where asymptomatic sigma perforation led to a generalized emphysema, which was initially attributed to a maxillary sinus infection due to Aspergillus and anaerobic bacteria.
Tuberculosis is still a major paediatric problem in many parts of Africa, and the diagnosis may be missed because of the unusual and varied clinical features in some children. This is illustrated by 5 cases which have been described who presented with (a) unilateral swelling of the leg associated with inguinal lymphadenopathy; (b) subcutaneous emphysema; (c) 'cystic lung' disease; (d) respiratory stridor and (e) abnormal behaviour.
Operative cholangiography is an important adjunct to laparoscopic cholecystectomy, a recently developed surgical procedure in which cholecystectomy is performed through four abdominal ports under sustained pneumoperitoneum and the direct vision of a video laparoscope. Operative cholangiogram can effectively identify incidental choledocholithiasis or anatomic variation in the biliary system that may significantly influence the surgical approach or postoperative management of the patient. Unique features portrayed on operative cholangiogram in patients undergoing laparoscopic cholecystectomy include unusual displays of pneumoperitoneum, subcutaneous emphysema, visualization of the unresected gallbladder, and overlying surgical hardware that must remain in the operating field during film exposure.
A 39-year-old woman who was involved in a high-energy trauma suffered a haematopneumothorax, subcutaneous emphysema, multiple fractures including a fracture of corpus Tx, and air in the epidural space.
Laparoscopic surgery is growing in popularity. As a result, laparoscopic procedures are being done on a broader and older patient population. These patients may have underlying cardiopulmonary disease that predisposes them to complications not seen in younger patients. Anesthesiologists should be aware of this possibility and of the problems inherent to the pneumoperitoneum necessary for laparoscopy. We present two cases involving elderly patients to illustrate cardiopulmonary complications that can occur during establishment or maintenance of the increased intra-abdominal pressures required for laparoscopic surgery. The first case describes a patient who developed bradycardia and asystole during insufflation for a laparoscopic hernia repair. The second case involves severe hypercarbia and a pneumothorax due to massive subcutaneous emphysema that developed during a laparoscopic colon resection.
A case of subcutaneous and retropharyngeal emphysema following a dental restoration is presented. The patient complained of swelling, tenderness, and a "crackling feeling" of her right face and neck, as well as pain in the back of her throat. Radiographs confirmed the diagnosis of interstitial air emphysema. The etiology of this unusual complication was the compressed air used in modern dental drills and syringes. Treatment consists of reassurance, observation, and prophylactic antibiotics. [Bavinger JV: Subcutaneous and retropharyngeal emphysema following dental restoration.
Bronchial fistulae in communication with atmospheric pressure can be identified by the presence of a squeaking sound heard over the chest wall during a Valsalva maneuver. Furthermore, these leak sounds can help identify the size, location, and communications of the bronchial fistulae. The size of the leak can be inferred by the pitch of the leak sound. Large leaks produce low pitched sounds, smaller leaks (or partially obstructed leaks) produce high pitched squeaks , and multiple leaking sites produce polyphonic leak squeaks . The bronchus responsible for the leak can be identified by cessation of the leak sound during balloon occlusion of the correct bronchial stump. A communication of a bronchial fistula with the chest wall facial plane produces massive subcutaneous emphysema and an early inspiratory click. This click suggests a check valve mechanism of air exiting the leaking bronchus.
Transtracheal oxygen delivery seems to be a safe procedure in the treatment of chronic obstructive pulmonary disease (COPD) with chronic hypoxaemia. Even so, serious complications do occur. Three patients in whom we used a subcutaneous tunnelled intratracheal oxygen catheter (ITO2C) are described. Surgical intervention was required in all because of complications from the procedure. One of the complications--tracheal and catheter obstruction with stridor and subcutaneous emphysema by granulomatous tissue--has to our knowledge not been reported before.
Spontaneous perforation of the oesophagus is extremely rare in children, as is perforation due to vomiting in pregnancy. We report the case of a 15-year-old in whom vomiting in early pregnancy resulted in oesophageal perforation with subcutaneous emphysema causing marked facial swelling in the absence of other signs. The more common clinical presentation of spontaneous oesophageal rupture (Boerhaave's syndrome) is discussed.
A 19-year-old man consulted a doctor for swelling of his neck and shortness of breath. The day before, he woke up with a slight cough and upper chest pain early in the morning. He went to school and spent the day as usual. He did not have a history of asthma or violent cough. The next day, chest radiography showed subcutaneous emphysema and pneumomediastinum. Computed tomography not only confirmed the presence of mediastinal and subcutaneous air, but also demonstrated a linear radiolucent stripe in the spinal canal corresponding to epidural emphysema. The patient did not have any neurologic findings. His general condition remained good except that his arterial blood oxygen saturation slightly decreased to 95%. Laboratory data were normal, except for serum IgE, which was elevated (2072 IU/ml). He stayed at rest and was treated conservatively and his symptoms improved within a few days. Seven days later, the intraspinal air and pneumomediastinum had resolved spontaneously on follow-up chest computed tomography (CT).
A previous publication by this author discussing complications of endoscopic intranasal ethmoidectomy indicated an overall complication rate of 29% in 90 patients (17% in 150 ethmoidectomies). Compared to published complications rates for traditional intranasal ethmoidectomy (2.7% to 3.7%), 17% is alarming and of concern. The complication results in 300 ethmoidectomies performed on 180 patients are presented. The overall complication rate was 9.3%. Only two further complications have occurred since the first reported series: a cerebrospinal fluid leak and one case of subcutaneous emphysema. Methods and techniques that have led to the reduction of complications are briefly discussed. Endoscopic ethmoidectomy is a valid, safe procedure in experienced hands.
The paper concerns the complications which appeared during 1822 laparoscopies and 141 hysteroscopies. The overall percentage of complications in presented material was 0.82% for laparoscopy and 2.8% for hysteroscopy. The most frequent complication during performance of laparoscopy was subcutaneous emphysema (8 cases). The most frequent complication during hysteroscopy was uterine wall perforation, which appeared in 3 cases during incision of dense and massive intrauterine adhesions. All patients with complications of gynecologic endoscopy recovered well.
Transthoracic fine-needle biopsy (TFNB) is a valuable method of recognizing changes in lungs, especially suspected of cancer. Such operations are cheap, don't demand expensive instruments and are possible to perform in each pneumonology ward, especially if they are an ideal supplement for bronchofibroscoping examination. The possibility of quick and effective performance of transthoracic biopsy shortens the diagnostics considerably. From January 1997 to April 1999 there were performed 406 operations of TFNB. There were 334 people operated on (294 men--74.5%; 85 women--25.5%), average age for the whole group of patients--62.8 (+/- 10.4 years). The patients were divided into two groups considering hospitalization places: I--patients from (not transported for operation)--135 (40.4%), II--patients transported for operation from another hospitals--199 (59.6%) The examination was performed under control of rtg apparatus (7600 OEC Medical System with mobile x-ray tube on a C-arm and laser localizer). The usual complication was an pneumothorax--52 cases (12.8%); drained--16 cases (3.9%). An average depth of inserting in an early pneumothorax is 6.56 (+/- 0.73), in a late pneumothorax--8.6 cm (+/- 1.75), (p = 0.0015). An average depth of inserting in a drained pneumothorax was 8.9 cm (+/- 2.17), in a non-drained pneumothorax 7.7 cm (+/- 1.3) (p = 0.024). Patients that had to be transported for the operation had pneumothoraxes that needed to be drained considerably more often: 14 cases in 199 comparing to 2 in 135 among patients not demanding to be transported (p = 0.02). Pneumothoraxes appeared more often after indicating tumors of smaller size, from 3 cm--21.6%; 3.1-6 cm--13.3% (p = 0.036). From another complications one could notice: hemoptysis--4 cases; subcutaneous emphysema--1 case; fever and shivers--1 case; hypotonia--2 cases; cough--1 case. Those complications were treated symptomatically or vanished themselves.
We present two cases of blunt external trauma to the trachea. The first was a 19-year-old man who had suffered rupture of the first tracheal ring as a consequence of attempting suicide by hanging from a cable. The second was an 11-year-old boy who fell from a bicycle and struck his neck against the handlebars. Fracture of the second tracheal ring was found at surgery. Both cases were treated by primary repair. A surgical exploration is essential in the case of subcutaneous emphysema, even if no respiratory distress is present and a radiological evaluation is negative. Follow up, according to the extent and type of injury, is recommended to prevent post traumatic stenosis of the trachea.
The rare case of a pneumopenis and pneumoscrotum after a thoracic operation is reported. Two subtypes--pneumatocele and subcutaneous emphysema of the scrotum--are differentiated on the basis of anatomy. The cases reported in the literature so far are reviewed. A therapeutic regimen is recommended.
