[Reconstruction of a crushed chest with HI-TEX PARP NT implant].

The authors present the case of a 57-year-old man with polytrauma, who was injured in a train accident. Together with other injuries, he also sustained multiple comminuted fractures on the left half of the rib cage. These subsequently required surgical intervention because of thoracic instability and impending lung injury. Extensive damage to the thoracic skeleton was treated by removal of the damaged tissues and replacement by the HI-TEX PARP NT implant. The presented procedure is being discussed as an alternative to metallic fixation in thoracic instability in cases of devastating injury or injury resulting in bone and tissue loss.

Urological complications of congenital nephrogenic diabetes insipidus--long-term follow-up of one patient.

A male with a severe form of congenital nephrogenic diabetes insipidus (diuresis 10 l per day) had megaureters, megavesica, large residuum and a history of three traumatic ruptures of the megavesica and a recurrent urinary tract infection (RUTI). Hemodialysis was introduced at 41 years of age. At age of 42, he underwent a bilateral retroperitoneoscopic nephrectomy to prevent further RUTI and 8 months later transplantation of a cadaver kidney. Intermittent catheterization is necessary due to residual urine in the urinary bladder.

[Diagnosis and treatment of liver injuries].

AIM: The aim is to specify contemporary diagnostic and therapeutic procedures of liver injuries. METHODOLOGY: The authors present a trial group of 117 patients with various stages of liver injuries hospitalized at the Traumacentrum Surgical Department of the Faculty Hospital in Plzen from 1.1.2000 to 31.9.2005. 61 injured (52.1%) were treated conservatively, 56 (47.9%) surgically, who underwent 87 procedures, in total. RESULTS: 10 polytrauma patients exited (8.5%) from a haemorrhagic shock (group Moore IV-VI). Six subjects (5.1%) had complications on hospitalization. Average hospitalization lasted 18 days (1-69 days). CONCLUSION: The basic diagnostic tools in liver injuries include "bed side" ultrasonography, spiral computer tomography, in more complicated traumas also MRI, angiography or endoscopic retrograde cholangiography. As a treatment strategy, conservative methods prevail in haemodynamically stable patients, regardless of the liver injury stage. The objective of the surgical management is to provide "damage control surgery", i.e. the first procedure is aimed at life-saving, no time-demanding surgical procedures (e.g. liver tamponade), management of hypothermia, haemocoagulation and metabolic acidosis.

[An inflammatory aneurysm of the abdominal aorta].

Inflammatory aneurysm of the abdominal aorta is a rare disorder, affecting approximately 3-10% of the population with a diagnosis of the abdominal aortic aneurysm. The principal etiological agents of the disorder include bacterial microorganisms, primarily Salmonella, Staphylococcus aureus, and Escherichia coli. However, in many cases the etiology od the disorder remains unclear and, likely, autoimmune and genetic dispositions may play a certain role, as well. The principal diagnostic procedures include ultrasound, CT and MRI examinations. The principal therapeutic procedures include open resection of the inflammatory aneurysm with complete removal of the infectious tissue and its replacement by a prosthesis or a vascular allograft "in situ" or through an extraantomical reconstructive procedure. New procedures also include endovascular therapy which is technically much simpler, less demanding for a patient, however, it may leave a potential infectious focus in the organism with a risk of further septic complications to follow. Therefore, the authors recommend a strictly individual treatment strategy in each patient with this serious disorder. In case of positive cultivation bacteriological findings, extended (a minimum of 6 weeks) antibiotic therapy and regular, long-term patient follow-up with regular visits, are essential.

[Miniinvasive laparoscopic or retroperitoneoscopic radical nephrectomy for the parenchymal tumor].

INTRODUCTION: Laparoscopic (LRNE) or retroperitoneoscopic (RRNE) radical nefrectomy originally published in 1991, respectively in 1993, began to be introduced in common practice at the end of the 20th century. In this work we summarize our findings gathered upon introduction of these methods. SUBJECTS AND METHODOLOGY: We present a group of 50 miniinvasive nephrectomies conducted during 2003-2004 (46 LRNE and 4 RRNE). LRNE was combined with ipsilateral adrenalectomy in five cases and with cholecystectomy in three cases (in all cases the LRNE was on the right side). RESULTS: The mean age of the patient subjects was 65 +/- 11 years (34-81). The blood loss was 134 +/- 201 ml (30-1200). The tumor size according to the CT was 50 +/- 13 mm (30-82). Histologically, 45x renal carcinomas, 4x oncocytomas, 1 x urothelial carcinomas were diagnosed. The drain was removed 2.1 +/- 0.9 days following the surgery. The mean hospitalization time was 6.1 +/- 1.6 days (4-9). Only a single major, however lethal, complication arised: In a 74-year old female, the left-sided LRNE due to the carcinoma pT3bG2 and at the same time vaginal hysterectomy, extraction of the renal preparation through the vagina and anterior and posterior vaginoplasty (for a prolaps) were conducted. The patient was repeatedly revised for haemoperitoneum and she exited on the 18th postoperative day due to pneumonia. The mean duration of the LRNE was 168 +/- 40 minutes (80-265). The combined LRNE and cholecystomic procedure lasted 265 minutes. The mean duration of the LRNE with CHE was 213 minutes, and of the LRNE with adrenalectomy was 170 minutes. In 4 cases of the RRNE (indicated three times due to preceeding major surgical procedures in the abdominal cavity and once for the Crohn's disease) the mean duration was 203 minutes. CONCLUSION: Miniinvasive RNE in TI tumors is a modem reproducible methodology suitable for application in clinical practice. The laparoscopic approach appears more appropriate. The retroperitoneoscopic approach is indicated mainly in cases of postoperative adhesions in the abdominal cavity.

Surgical treatment of benign liver tumors.

In their report, the authors evaluated in their report a group of patients with benign liver tumors. These patients were treated at the Surgical Department of the Teaching Hospital in Pilsen from 1999 up to 2004. The evaluation of the investigated groups compared of 43 sick patients was based on the prospect of their individual diagnoses, types of performed surgeries, the time period of their therapy and complications, which had occurred in the course of their surgical treatment. In the group of 24 patients with liver haemangioma, the authors recorded 14 patients with focal nodular hyperplasia, 3 patients with hepatocellular adenoma and 2 patients with other types of benign tumors--multilocular cystic lymphangioma of the liver and one hamartoma. Among these patients there was 0% mortality and 6.9% morbidity.

The contribution of MRI to the diagnosis of diffuse meningeal lesions.

We analysed MRI findings in patients in whom a diffuse abnormality of the meninges was revealed by MRI. We looked at T1 and T2-weighted spin-echo or fast spin-echo images and contrast-enhanced T1-weighted images. There were 15 patients with abnormalities on MRI, clinically suspected in ten. Four had meningoencephalitis, one meningeal and subcortical sarcoidosis nodules, four meningeal malignancies--one disseminated oligodendroglioma, one with meningeal infiltration around an adenocarcinoma, three meningeal infiltration by a haematological malignancy, and one a chronic subdural haematoma without a history of injury. We excluded patients with primary meningeal tumours and typical injury-related meningeal bleeding. The relatively small number of patients is due to both the infrequency of diffuse meningeal disease and to the low frequency of suspected meningeal pathology as an indication for MRI. The latter's diagnostic contribution is greatest in infectious disease and neoplastic infiltration, and less obvious in haematological malignancies. Contrast-enhanced T1-weighted images are most useful.

[Intralobar pulmonary sequestration].

Sequestration is defined as an area of abnormal pulmonary tissue not connected with the bronchial tree, supplied by an aberrant systemic artery and without a normal pulmonary function. Extralobar (ELS) and intralobar (ILS) forms are distinguished. During the year 2002 the authors diagnosed and operated upon two cases of the intralobar form of pulmonary sequestration, and in last 25 years five cases - 4 x ILS and 1 x ELS. Reported are a 35 year old man with relapsing infections of the sequester and a 21 year old woman where the sequestration was accidentally found without clinical symptoms. The focus was localized in both cases in the left lower lobe of the lungs, anomalous supply arteries derived from the thoracic aorta. Venous drainage of the sequester was different - in the man a systemic drainage via the v. azygos, in the woman via the pulmonary veins was found. In one case the diagnosis was made on the basis of angiography and computer tomography, in the other case it was made on the basis of multidetector CT angiography (MDCTA). Both findings were treated by primary surgical intervention lobectomy. The postoperative course was uneventful.
