Use of Ilizarov distraction modified by Cattaneo and Catagni for femoral lengthening.

Ilizarov distraction device with proximal fixation by Cattaneo and Catagni has been used for femoral lengthening in 13 patients. Planned femoral elongation, fast remodeling of the newly formed bone and intended correction of the anatomical and mechanical axis of the limb have been achieved in all cases independently of the level of corticotomy. Full weight bearing was maintained during entire period of treatment.

[Results of surgical peritalar release with elongation of the lateral column of the foot in treatment of congenital veritcal talus].

Clinical and radiological results of surgical treatment of congenital vertical talus with the method introduced by the author have been presented. Along with Ingram's peritalar release and Grice's extra articular arthrodesis the author introduced elongation of the lateral column of the foot by interposing a bony graft into the calcaneocuboid joint. Five feet in children aged 5 on an average have been operated. An average follow-up was of 5 years. Clinically, three results were rated excellent and two good, radiologically two were excellent, two good and one fair. The results were assessed with a point scale, parameters worsening the outcome are presented in the tables.

[Pseudoaneurysm of both superficial femoral arteries complicating coronary angiography: case report].

A 58 years-old patient with aortic valve disease was admitted to our hospital for coronarography. Coronarography by transfemoral route bilaterally failed and eventually the coronary arteries were visualised by the transaxillary route. After the study bilateral pseudoaneurysms of the superficial femoral arteries were diagnosed clinically and confirmed by color-Doppler and angiographic studies. Surgical therapy was successful. Causes, nature, diagnosis and surgical as well as nonsurgical therapy of the femoral artery pseudoaneurysms complicating percutaneous transfemoral cardiac catheterization are discussed.

[Coexistence of WPW syndrome, coronary disease and segmental disorders of myocardial contraction. Diagnostic difficulties. Description of a case].

A 61 years old patient with Wolff-Parkinson-White's syndrome, and hypertension was admitted to the CCU, because of the first episode of substernal chest pain. ECG was deformed by Wolff-Parkinson-White's syndrome, type B, with accessory pathway located on the right side, without evolution. Serum enzymes remained low. Echocardiography showed akinesis of the posterior wall and hypokinesis of the lateral wall (the same contraction disorders were described in previous echocardiographical examination 5 years ago), it was observed that the first portion of myocardium to contract was the base of the right ventricle. To elucidate the etiology of the contraction disorders, scintigraphy of the heart, using Thallium 201, was performed, showing normal perfusion of the myocardium. To illustrate the dependence of the contraction disorders and abnormal depolarization pattern of the heart, echocardiographical examination was repeated, confirming the previous results, then 100 mg of Ajmaline was given to the patient intravenously, and echocardiographical examination was continued. Administration of the drug caused antidromic atrioventricular re-entrant tachycardia during which the lateral wall of the heart had been contracting properly. This case shows contraction disorders of the heart caused by the abnormal depolarization pattern, resulting from the presence of accessory pathway. It also illustrates the diagnostic difficulties in patients with Wolff-Parkinson-White's syndrome and suspected myocardial infarction, at the same time showing that scintigraphy of the heart might be very helpful in such patients. This case confirms the usefulness of echocardiography for localization of the accessory pathway.

[Use of Dynasplint in prevention of muscular contractures in limbs undergoing lengthening].

Dynamic splinting with Dynasplint for prevention of muscular contractures and subluxations in the joints during lower limb lengthening in 10 children has been used. In all cases the splint successfully prevented subluxation in the knee and the foot deformity. Ability to move splinted joints allowed effective rehabilitation. The splint was well tolerated by all the patients during whole period of distraction.

[Use of magnetotherapy for treatment of bone malunion in limb lengthening. Preliminary report].

Two children with bone malunion after lengthening of congenitally shortened lower leg have been presented. The crus has been elongation 8 cm by Ilizarov method in 9 years old boy and 5 cm elongation of the tibia has been achieved with the use of Bastiani method in 8 years old girl. In both cases malunion has occurred. The radiographs revealed pseudoarthrosis (the girl, 6 month after operation) and centrally located bony defect (the boy, 2 months postoperatively). In both cases pulse sinusoidal magnetic field was applied successfully with cortical bone and marrow cavity restored in 2 months.

[The value of ultrasonography in monitoring limb lengthening].

The authors attempted to assess the value of ultrasound for monitoring of the new bone formation at the site of distraction in patients undergoing limb lengthening after Bastiani. Twenty patients were assessed; 12 cases of femur lengthening and 8 cases of tibia lengthening. It was found, that ultrasound allowed to detect the new bone formation visible as hyperechogenic foci as soon as 4 to 14 days postoperatively, while regular radiology showed this only 4 to 8 weeks after operation. Detection of the new bone formation at the site of lengthening permits, in authors opinion, to choose an optimal onset of distraction and its pace according to the speed of bone formation. Regular ultrasound monitoring prevents premature bone union or disintegration of the newly generated bone in case of to slow or to fast distraction respectively. In two cases sonography early demonstrated cystic changes at the location of distraction. It also permits detection of an axial displacement of the fragments of bone in every case.

[Technique of surgical treatment for congenital clubfoot using complete subtalar release by the Cincinnati approach].

The technique of congenital clubfoot surgical treatment based on independently described method by Mc Kay and Simons is delineated. We have modified skin incision making it ca 2 cm above the calcanean tuber in order to facilitate an access for elongation of the calcaneal tendon. In some cases the procedure was supplemented with cuneonavicular and first tarsal-metatarsal capsulotomy and tibialis anterior muscle tendon transfer to the dorsum of the first metatarsal bone.

[Programmed electrical stimulation of the heart in relation to left ventricular contractility in ischemic heart disease].

To determine the relation between left ventricular contractility disorders and the inducibility of serious ventricular arrhythmias, 83 patients (pts) with ischaemic heart disease and ventricular tachycardia (VT) or fibrillation (VF) in history and/or Lown's class IVb arrhythmia in 24-hour Holter ECG monitoring were evaluated by means of echocardiography and programmed electrical stimulation (PES) of the heart. Inducible VT or VF were observed in 66% of pts: sustained monomorphic VT (SMVT) in 33%, nonsustained VT (NSVT) in 28% and VF in 6%. VT or VF were significantly more frequent in patients with VT/VF in history (91% vs 42%, p less than 0.001), SMVT (48% vs 17%, p less than 0.01) as well as NSVT (38% vs 17%, p less than 0.01). Low ejection fraction (EF less than 40%) was observed in 18 pts (22%), VT/VF was inducible in 94% of them, while only in 57% with EF greater than or equal to 40%, p less than 0.01, SMVT in 39% vs 30%, NSVT in 33% vs 25%. Among 21 pts (21%) with left ventricular (LV) dyskinesis in 91% of pts while only in 55% without it, p less than 0.01, SMVT in 53% vs 26%, p less than 0.05. We concluded that in patients with previous myocardial infarction, VT/VF in history and abnormal LV contractility full haemodynamic, angiographic and electrophysiologic examination should be performed to determine their risk of sudden death due to serious ventricular arrhythmia before final decision about the mode of treatment.

[Late ventricular potentials and ventricular arrhythmia in patients with stable ischemic heart disease].

Ischaemic heart disease especially after previous myocardial infarction can predispose to the life-threatening ventricular arrhythmias. Late potentials (LP) are confirmed parameters predicting patients prone to sudden cardiac death in ventricular arrhythmias mechanism. Late potentials registered noninvasively from the body surface were analysed in 86 patients with stable ischaemic heart disease (67 males and 19 females aged 35-67, mean 53 years). Registration of signal average electrocardiograms (SA-ECG) were performed by Simson technic (X, Y, Z orthogonal leads) using identical analysing systems and quantitative SA-ECG criteria in all three participating centers. In all patients ventricular arrhythmias detected on 24-hour ecg Holter monitoring were assessed. The localisation of previous myocardial infarction and echocardiographic assessment of left ventricular function were also analysed in each case. The results of SA-ECG were correlated with these clinical findings. Late potentials were detected (according to two or three accepted criteria) in 16 pts (19%), in 53 pts (61%) SA-ECG were normal but in other 17 pts (20%) abnormal SA-ECG (according to only one criterium) were registered. Out of these 17 pts with abnormal SA-ECG, 14 pts had prolonged filtered QRS duration as the only incorrect SA-ECG parameter. Comparative analysis between studied groups shows higher incidence of previous Q-wave myocardial infarctions in patients with LP and with abnormal SA-ECG than in patients with normal SA-ECG (63% and 71% vs 43% respectively; p less than 0.01). Ventricular arrhythmias observed in studied patients occurred with similar frequency in all groups however in patients with LP and with abnormal SA-ECG complex ventricular arrhythmias were more common than in group with normal SA-ECG (56% and 53% vs 49% respectively: NS).(ABSTRACT TRUNCATED AT 250 WORDS)
