Operative outcome of minimal access aortic valve replacement versus standard procedure.

BACKGROUND: to determine the advantages and/or risks of minimal access aortic valve replacement compared to standard sternotomy procedure. METHODS: from January 1997 to December 2001, 271 consecutive adult patients underwent isolated aortic valve replacement of which 174 underwent a minimal access procedure (Group 1) and 97 a standard procedure (Group 2). The preoperative variables of both groups were comparable. Retrospective analysis of postoperative outcome was performed. RESULTS: follow-up was complete and ranged from 6 months to 4 years. Overall in-hospital mortality was 3.3% (respectively 2.8 and 4.1%). No statistical difference was noted regarding operative time variables, mortality rate and hospital stay. There was a significant higher incidence of revision (p = 0.018) and late pericardial effusion (p = 0.022) in the minimal access group. Also trends were in favour of the standard group for incidence of postoperative pneumothorax and pericarditis constrictiva. CONCLUSIONS: minimal access aortic valve replacement is a safe and reliable technique, but carries the risk of incision-related morbidity. Proper patient selection and perioperative management is mandatory.

Tracheobronchial compression of vascular origin. Review of experience in infants and children.

BACKGROUND: Tracheobronchial compression of vascular origin is an uncommon but important cause of respiratory distress in infants and children. We reviewed our surgical experience with 31 children, presenting vascular tracheobronchial compression. METHODS: Thirty-one children, with a median age of seven months, were operated on for airway and/or oesophageal compression secondary to vascular anomalies. Diagnostic findings, mainly established by bronchoscopy and angiography, revealed several pathologic disorders such as right aortic arch with aortic diverticulum in 10, double aortic arch in five, innominate artery compression in six, arteria lusoria in four, and pulmonary artery sling in one patient. Five children developed tracheobronchial compression after previous repair of a complex congenital heart disease. Clinical symptoms on admission were dominantly stridor, recurrent airway infection, dyspnea, respiratory distress and upper digestive complaints such as dysphagia and gastroesophageal reflux. RESULTS: Surgical relief was successful in 30 patients. Only one child with palliated tetralogy of Fallot and pulmonary artery sling died because of intractable extensive tracheobronchial stenosis. Late follow-up over three to 90 months showed a symptom-free evolution in most patients, including one reoperation for recurrent compression and one late death. CONCLUSIONS: Tracheobronchial compression by vascular structures in childhood is uncommon and may be masked by nonspecific respiratory symptoms, resulting in an often delayed diagnosis. Once imaging studies have clearly delineated the causal pathologic vascular structures, surgical correction is often straightforward and effective, in spite of the common presence of tracheobronchial malacia.

Aortic dissection and Turner's syndrome.

Cardiovascular malformations, especially coarctation of the aorta and bicuspid aortic valve, are common in patients with Turner's syndrome. Only 46 patients with aortic dissection and/or rupture have been described. All patients had associated aortic dilation or aneurysm. In all cases except three, involvement of the ascending aorta was present, making surgery often imperative. We describe a rare case of a DeBakey type IIIb aortic dissection (without involvement of the proximal aorta) in a patient with Turner's syndrome mosaicism. The dissection occurred two weeks after a caesarean section because of eclampsia. No aortic dilation or other cardiovascular malformations were found. The distal extension and uncomplicated nature of the dissection indicated medical management. After fifteen months of follow-up, she is clinically doing well and repeated CT scan shows a stable dissection of the descending and abdominal aorta without dilation.

Dissemination of the use of the electronic patient record in high-quality workmanship: the regional IT consultant for primary care doctors.

The number of general practitioners in Denmark with electronic patient record systems is rising. More than 80% of all GP practices now have computerised patient record systems. These medical practices communicate electronically with hospitals, laboratories, pharmacies and county councils. With the procurement of electronic patient record systems and connection to the Danish Healthcare Data Network, the vast majority of patient data in medical practices is now held in electronic form. This offers good opportunities for the data to be used not just in the consultation situation but for quality development and the monitoring of quality targets in general practice as well. However, the individual medical practices do not utilise the opportunities presented to them by their computer systems. The Quality Development Committee in Funen County Council has therefore set up an IT consultant scheme to provide guidance and instruction in the various computer systems found in general practice today, in order to optimise the use of data for quality monitoring.

Traumatic pseudoaneurysm of the abdominal aorta.

A traumatic pseudoaneurysm of the abdominal aorta is a rare entity, occurring as the result of a missed aortic lesion at the time of the initial injury. Therefore, clinical suspicion and careful abdominal exploration at first laparotomy is mandatory to prevent aortic pseudoaneurysm formation and its risk of delayed rupture. We present a case of successful surgical treatment of a suprarenal aortic false aneurysm, presenting 4 weeks after a life-threatening gunshot wound in a 13-year-old child.

Combined repair of upper sternal cleft and tetralogy of Fallot in an infant.

We report on a 2-month-old infant with the unusual association of an upper sternal defect and tetralogy of Fallot. Surgical correction of the cardiac disease consisted of closing the ventricular septal defect and relief of the right ventricular outflow tract by infundibuloplasty. The already less compliant bony thorax of the infant made direct approximation of the upper sternal defect only possible with adjuvant bilateral chondrotomies. Sternal cleft repair is advised during the very first weeks of life, during which complete correction of the rarely associated tetralogy of Fallot can be successfully performed.

Nonvalved homografts of thoracic aorta in operation for complex congenital cardiac disease.

BACKGROUND: In contrast to the wide and successful use of valved aortic and pulmonary homografts, the non-valved prolongation of the thoracic aorta for the repair of some complex congenital heart diseases has rarely been described. We present here our experience with the use of descending aorta and aortic arch homografts as non-valved conduits for the surgical repair of complex cardiac malformations in 8 patients. METHODS: One atriopulmonary conduit replacement four extraatrial cavopulmonary connections, and one intraatrial cavopulmonary repair were achieved by means of a homograft of the descending aorta with a diameter of 15 to 17 mm. Three pulmonary unifocalization procedures were carried out in 2 more patients using a curved homograft of the aortic arch with a diameter of 18 mm. Except for 1 patient, whose incompetent common atrioventricular valve was replaced with a mechanical prosthesis, all other patients were managed without anticoagulation. RESULTS: No conduit-related complications were seen during a follow-up of 18 to 42 months. One patient died perioperatively during an emergency central repair of the right ventricular outflow tract after bilateral unifocalization with arch homografts. Another patient died suddenly 4 months after cavopulmonary connection. The remaining 6 patients are currently doing well. CONCLUSIONS: Regardless of the complexity of the underlying malformations, we are encouraged to use nonvalved thoracic aortic homografts in the repair of congenital cardiac diseases because of the reduction in thrombotic, hemorrhagic, and infectious complications associated with their use; convenience in handling; and their versatility in size and shape.

Laparoscopic-assisted surgery of the spleen: clinical experience in expanding indications.

Between January 1993 and November 1995 laparoscopic surgery was used in 21 patients with a variety of splenic diseases, namely idiopathic thrombocytopenic purpura, congenital spherocytosis, lymphoma, leukemic infiltrative disease, splenic infarction, trauma, or splenic cyst. Total splenectomy was carried out laparoscopically in 16 patients. Conversion to open splenectomy was necessary in two other patients because of intractable bleeding. Two patients with a splenic cyst underwent laparoscopic unroofing of the cyst. Conservative hemostasis of a spleen injury grade II was carried out in a child after blunt trauma. The total mean duration of the laparoscopic procedures was 158 min and the mean blood loss volume was 350 ml, both conversions being excluded. Postsurgical recovery was excellent and the average hospital stay was 5 days, including the patients with conversion. There were no significant postoperative complications. Our observations indicate that an increasing number of surgical diseases of the spleen can be managed adequately by a less invasive laparoscopic approach. However, the criteria for using this procedure are in an expanding phase and are still mainly dependent on the surgeon's technical experience.

Contribution of endoscopy to early diagnosis of hypertrophic pyloric stenosis.

The diagnostic accuracy of ultrasonography and gastrointestinal endoscopy was compared in 63 infants who were operated on for infantile hypertrophic pyloric stenosis. Endoscopy was far more accurate than ultrasonography, the diagnosis being made in 97 and 81% of the cases, respectively. The difference between the techniques was even more obvious in the younger patients and in those with a short history of vomiting. The ability to detect coexistent or other causes of vomiting with endoscopy appeared advantageous. The endoscopic procedure is easily done without general anesthesia and was without complications in our series. We recommend endoscopy as an important tool in very young patients with few clinical signs other than vomiting, allowing for appropriate treatment without delay.

Is the use of ankle saphenous vein for carotid artery patch closure justified?

Saphenous vein patch angioplasty has been introduced to prevent early and late restenosis after carotid artery endarterectomy. We describe a case of vein patch rupture on the first postoperative day, resulting in death of a hypertensive female patient. Although the incidence of this complication is low (0.5 to 1%), the morbidity and mortality rate is dramatically high when it occurs. In similar cases published, saphenous vein harvested from the ankle is involved almost exclusively, suggesting that small-diameter veins have a higher risk of rupture when used as a carotid patch. Old age, female gender, diabetes and arterial hypertension seem to be further factors negatively influencing the physical properties of the vein. Therefore, if a venous patch is needed in selected patients most probably in female patients with small internal carotid arteries, it seems appropriate to use the proximal part of the saphenous vein from the groin or the thigh.
