Results of surgical treatment of cervical esophageal diverticula.

On the basis of 20 years' experience, the authors present the immediate and long-term results of operative treatment of Zenker's diverticulum. Comparison of two methods of surgery--diverticulopexia (in 21 patients) and excision (in 16), both associated with upper esophageal sphincter myotomy--shows good immediate and long-term results (from 1 to 19 years), with disappearance of symptoms (dysphagia) in all patients. There was no perioperative mortality. Postoperative complications were most commonly of pulmonary origin and were observed in a third of patients in both groups. In two patients from the group treated with excision, a leak from the suture line occurred, which healed spontaneously. These two patients had transient dysphagia in the postoperative period. On the basis of this analysis, the authors conclude that diverticulopexia is a safer surgical procedure than excision, giving less complications and a very good long-term functional result.

[Results of surgical treatment for Zenker's diverticula].

From 1976 to 1996, thirty nine patients were surgically treated for pharyngoesophageal diverticulum. The present study aimed to compare two methods of operative treatment of Zenker's diverticulum: excision (group I) and pexy, both of which were associated with upper esophageal sphincter myotomy. The main indication for surgery was dysphagia. The diagnosis of Zenker's diverticulum was based on clinical symptoms and the result of upper GI tract barium examination. In 75% of patients the diameter of diverticulum exceeded 2 cm. No patient died in the perioperative period. The main complications observed in the postoperative period were of pulmonary origin. In group I (excision) a leakage from the suture line occurred in 2 patients (12.5%). Time of follow-up ranged from 1 to 20 years (mean: 7 years). The comparison of both methods of treatment employed is in favour of diverticulopexy, being a safer and less complications-bearing method, although both of them give similar functional results.

[Arterial hypertension complicated by aortic dissection. Clinical analysis, results of conservative treatment].

Detailed analysis of 21 patients suffering from arterial hypertension complicated by aortic dissection, who were treated non-surgically was performed. Signs and symptoms of aortic dissection appeared the most frequently in the age between 50 and 69. In 14 (66.7%) cases proximal (type A) and in 7 (33.3%) distal (type B) dissection were diagnosed. During acute phase 15 patients complained of pain and 6 did not. Smoking and family history of arterial hypertension were the commonest risk factors in this group. Proximal dissection was more frequently connected with painful course of the dissection whereas distal with painless. Detailed analysis of clinical data and non-invasive treatment during acute phase (first 14 days since onset of pain) was performed. During ambulatory observation which lasted 3-75 month (mean 34.3 month) 5 (25%) patients died, 15 (75%) are still alive.

[Unusual clinical course of ruptured aortic aneurysms--report of three cases].

Three cases of unexpected clinical course of ruptured aortic aneurysm have been presented in patients of their 7th decade life. All of them had arterial hypertension. Signs and symptoms on admission to hospital (dysphagia, chest and interscapular pain, hematemesis, abdominal pain, elevated body temperature and diminished exercise tolerance) were non-specific of aortic aneurysm, suggesting other disease. Dramatic clinical course with hypovolemic shock in two cases led to death. One of them refused surgery. In the third one, in spite of blood effusions to pleural cavity, pericardial sac and mediastinum, effective hypotensive therapy with a preservation of the slow heart rate and fluid evacuation from pericardial sac, gave the opportunity to perform elective surgery. Aortic dissection often presents an atypical course and when suspected, all available imaging technics including computed tomography and nuclear magnetic resonance must be used.

Results of long-term medical treatment of patients with arterial hypertension complicated by aortic dissection.

UNLABELLED: The purpose of the study was to analyse results of ambulatory treatment of patients with arterial hypertension complicated by aortic dissection. Twenty patients (19 men, one woman), aged between 39 and 72 years, underwent full physical examination. In all cases the diagnosis of aortic dissection was confirmed by at least two different imaging methods (ultrasonography, digital subtractional angiography, computer tomography or nuclear magnetic resonance). During follow-up (3-75 months, mean 34.3 months), physical examination was performed every 6-8 weeks, chest radiograph was taken once a year. All patients controlled their blood pressure (BP) at home. According to the mean number of in-home BP measurements per month all patients were divided into two groups: group I good (n = 10) and group II bad compliers (n = 10) (28 +/- 30 vs 3 +/- 2 in-home BP measurements a month). Ten patients (6 in group I, 4 in group II) underwent 24 h automatic BP measurement examination. Blood samples were collected for serum cholesterol and uric acid measurements. All patients suffered from arterial hypertension and in five cases at least one parent suffered from this disease. Only three of 20 have never smoked cigarettes. Elevated serum cholesterol was observed in 10 (50%) cases and elevated uric acid in six (30%). Proximal (type A) aortic dissection (DeBakey classification type I and II) was found in 13 patients, distal aortic dissection (type B) in seven patients. All patients were treated with beta-blockers. In 75% of 20 cases three or more hypotensive drugs were used simultaneously to control BP. In the group I lower values of mean of maximal SBP (160 +/- 10 vs 177 +/- 7 mm Hg, P < 0.05) and lower mean circadian heart rate (58.6 +/- 7.5 vs 80.9 +/- 7.9 beats/min, P < 0.005) were observed. The most frequent complaints were intermittent claudication, 9 (45%); angina pectoris 8 (40%), other chest pain, 4 (20%). During follow-up period (3-75 months, mean 34.3 months) five of 20 patients (25%) died (all had proximal, type A dissection) and 15 of 20 patients (75%) are still alive. All deaths in group II were sudden, whereas the only one in group I was because of chronic renal insufficiency. Mortality rate in the two groups were 10% (one of 10) vs 40% (four of 10), respectively, in groups I and II. IN CONCLUSION: patients who control their BP more often have the lower values as well as lower heart rate and therefore a better prognosis.

[Left coronary artery-pulmonary artery fistula. Case report].

A case of a 45-year-old male with anterior descending branch of the left coronary artery fistula to the main pulmonary trunk is reported. The patient was admitted because of a retrosternal pain. ECG showed ST-elevation in leads V2-3. This was first episode of anginal symptoms. The authors suggest that the single episode of coronary pain may have been provoked by faintness (following alcohol consumption) in the mechanism of the steal syndrome or by coronary spasm. A fistula (on coronarography) was diagnosed (the coronary arteries showed no changes). The value of the shunt calculated via Flick's method was 1.1 l/min. Exercise test, 24-hour ECG recording as well as stress thallium scintigraphy did not reveal post-exertion ischemic changes. During a 17-month post hospitalization follow-up the patient reported no anginal symptoms. Because of the small shunt and asymptomatic follow-up no surgical treatment was recommended.

[Cor triatriatum with mitral incompetence--contribution to diagnosis and therapy].

Authors presented difficulties in diagnosis of the cor triatriatum with the mitral incompetence in 34 years old female patient. Diagnosis was based on two-dimensional and doppler echocardiographic examinations and then angiocardiographically proved. Therapy consisted in resection of the fibromuscular intraatrial septum and implantation of the St. Jude mitral prosthetic valve.

Cardiac chambers and their walls in cardiomyopathies as evaluated with CT.

Thirty-two patients with cardiomyopathy, 25 with hypertrophic and 7 with dilated form were examined by cardiac catheterisation, left ventriculography, selective coronary angiography and ungated cardiac computed tomography. Diffuse hypertrophy, localized hypertrophy and dilated cardiomyopathy were diagnosed and assessed quantitatively based on CT linear, surface and volumetric parameters of cardiac morphology. Absolute septal thickness and left ventricular mass measured in CT image are the most discriminative attributes.
