Abstract

Patients with brain arteriovenous malformation (AVM) have a certain risk to bleed, and the goal of this study was to examine the effect of radiological and clinical predictive characteristics of AVM hemorrhage using multidetector computed tomographic (MDCT) angiography. The study included a series of 57 patients, mean age 35.46 years, who were diagnosed during their hospitalization at Clinical Department of Neurosurgery, Clinical Center of Serbia, in the period from January 2008 to March 2016. In all patients, the diagnosis was made using MDCT angiography. Two groups of patients were observed. The first group included patients who did not initially present with hemorrhage, while the second group initially presented with hemorrhage. Both groups were treated with medical therapy or a combination of medical therapy with embolization/surgery/radiotherapy. Deep venous drainage (p<0.05), combined arterial supply from different basins (p<0.05) with a length >60 mm, venous dilatation present in the drainage vein (p<0.01), and the angle of casting sup-ply arteries in the nidus (p<0.01) carry a risk of repeated bleeding. In the group of patients who had initial hemorrhage, the mean value of the casting angle size was 130°, while in the group that did not have initial bleeding the mean value of the measured angle size was 103.81° with standard deviation of 17.21° (p<0.01). In conclusion, AVMs with deep venous drainage from the carotid and vertebrobasilar basin, the length of the feeding arteries >60 mm, the angle of the casting feeding arteries in the nidus ≥130° and dilatation and/or venous aneurysm of drainage vessel are predictive for clinical presenting by hemorrhage., Bolesnici s arteriovenskim malformacijama mozga (AVM) imaju određen rizik za krvarenje pa je cilj ove studije bio ­ispitati utjecaj radioloških i kliničkih prediktivnih karakteristika AVM za hemoragiju pomoću multidetektorske CT angiog-rafije (MDCTA). U studiju je bilo uključeno 57 bolesnika srednje dobi od 35,46 godina kojima je dijagnoza postavljena na Institutu za radiologiju i magnetskom rezonancijom dok su bili hospitalizirani na Klinici za neurologiju Kliničkog centra Srbije u razdoblju od siječnja 2008. do ožujka 2016. godine. Svim bolesnicima je dijagnoza postavljena pomoću MDCTA. Praćene su dvije skupine bolesnika. Jednu skupinu činili su bolesnici kod kojih se AVM u početku nije manifestirala krva-renjem, dok se druga skupina odmah prezentirala hemoragijom. Obje skupine su liječene medikamentnom terapijom ili kombinacijom medikamentne terapije s embolizacijom/kirurškom intervencijom/radioterapijom. Duboka venska drenaža (p<0,05), kombinirani arterijski dovod iz različitih slivova (p<0,05) s dužinom >60 mm, prisutna venska dilatacija na dre-nažnoj veni (p<0,01) i kut ulijevanja dovodnih arterija u nidus (p<0,01) nosili su rizik ponovljenog krvarenja. U skupini bolesnika koji su imali inicijalnu hemoragiju srednja vrijednost veličine kuta ulijevanja je bila 130o, dok je u skupini koja nije imala inicijalno krvarenje srednja vrijednost izmjerenog kuta bila 103,81o sa standardnom devijacijom 17,21o (p<0,01). U zaključku, AVM s dubokom venskom drenažom iz karotidnog i vertebrobazilarnog sliva, dužinom dovodne arterije >60 mm, kutom ulijevanja dovodne arterije u nidus ≥130° i dilatacijom i/ili aneurizmom drenažne vene su prediktivni model za kliničko prezentiranje hemoragijom.

Abstract

Here we present two cases of gastrostomy insertion via laparotomy in patients with malignant esophageal disease. Patients were ASA (American Society of Anesthesiologists) physical status III and IV. The patients presented as very high risk for general anesthesia, so we decided to use unilateral left sided paravertebral block (PVB) on four thoracic levels along with contralateral local infiltration at the gastrostomy insertion site. We present two cases, one of them a 57-year-old male ASA III patient scheduled for a gastrostomy procedure due to esophageal cancer with infiltration of the trachea. We also present a case of a 59-year-old male patient, ASA IV status, scheduled for the same procedure due to advanced esophageal cancer with a fistula between the left main bronchus and the esophagus and metastases in the left lung. The paravertebral space was identified with the use of an 8 Hertz (Hz) linear ultrasound probe and a nerve stimulator. Paravertebral block was successfully used for insertion of a gastrostomy, thereby enabling adequate anesthesia and perioperative analgesia without hemodynamic or respiratory complications., Prikazujemo dva slučaja postavljanja gastrostome laparotomijskim putem kod bolesnika s malignom bolesti jednjaka. Bolesnici su prema Američkom anesteziološkom društvu (American Society of Anesthesiologists, ASA) klasificirani kao ASA status III i IV. Zbog vrlo visokog rizika za primjenu opće anestezije prikazanim bolesnicima odlučili smo primijeniti prsni paravertebralni blok na četiri razine s nasuprotnom lokalnom infiltracijom mjesta postavljanja gastrostome. Prikazujemo dva slučaja; jedan je bio 57-godišnji ASA III bolesnik predviđen za postavljanje gastrostome zbog karcinoma jednjaka s infiltracijom traheje. Također prikazujemo 59-godišnjeg ASA IV bolesnika predviđenog za isti zahvat zbog uznapredovalog karcinoma jednjaka s fistulom između glavnog lijevog bronha i jednjaka uz metastaze na lijevom plućnom krilu. Paravertebralni prostor je identificiran primjenom ultrazvučne linearne sonde od 8 Hertza (Hz). Paravertebralni blok je uspješno primijenjen za postavljanje gastrostome omogućavajući time zadovoljavajuću anesteziju i perioperacijsku analgeziju bez hemodinamskih i respiracijskih komplikacija.

Abstract

The verified presence of a glioblastoma multiforme (GBM ) tumor in the motor area of the brain, in a patient lacking preoperative neurological deficit, offers no certainty that the tumor can be radically removed without the possibility of causing postoperative motor deficit. We present a series of 60 patients hospitalized at the Clinical Department of Neurosurgery, Clinical Center of Serbia in Belgrade between October 2011 and February 2015, harboring tumors located within and in the vicinity of the motor zone of the brain. By using Karnofsky‘s index (KI), the pre- and postoperative conditions of the patients were evaluated. Regarding electrical stimulation of the motor cortex, significantly lower values of the electrical current intensity, frequency, and pulse wave duration (p, Jasna prezentacija tumora mozga u području motorne zone kod bolesnika koji prijeoperacijski nisu imali slabost ekstremiteta nije jamstvo da se on može radikalno odstraniti bez poslijeoperacijskog neurološkog deficita. Prikazujemo niz od 60 ispitanika sa supratentorijalnim tumorima lokaliziranim u i oko motorne zone mozga, koji su hospitalizirani na Institutu za neurokirurgiju KCS u Beogradu u razdoblju od listopada 2011. do veljače 2015. godine. Procjena prije- i poslijeoperacijskog stanja bolesnika je vrednovana ljestvicom Karnofski indeksa (KI). Iz serije su isključeni bolesnici s recidivom tumora i bolesnici čiji je KI kod prijma bio manji od 70. Tijekom procedure elektrostimulacije motornog korteksa potrebne su značajno manje vrijednosti jačine struje, frekvencije i pulsnog vala (p

Abstract

Chronic pleural effusion requires pleural and lung biopsy in more than 60% of patients. Open lung biopsy was formerly considered as the most reliable diagnostic method, whereas now the procedure is mostly performed via video-assisted thoracoscopy. During the last ten-year period (1995­-2005), 96 patients aged 31-72 (mean age 53) years were operated on at University Department of Thoracic Surgery, Jordanovac University Hospital for Lung Diseases by video-assisted thoracoscopy in general anesthesia. All biopsies were done by clamp sampling from parietal or visceral pleura, and in 31 patients lung tissue was sampled by endostapler wedge resection. Conversion to mini-thoracotomy was needed in only 12 patients, due to massive adhesions. Tissue samples were referred for histopathologic analysis. After the procedure, the patients had a thoracic drain connected to negative pressure. Histopathologic diagnosis was made in almost all patients, yielding a 97% success rate. In 16 patients, drain airflow had to be prolonged to more than 5 days, while the mean drainage duration was 4 days and mean hospital stay 8 days. Talc pleurodesis was performed in most patients with malignant effusion to stop effusion accumulation. Video-assisted thoracoscopic biopsy allows for adequate pleural and lung sampling with a high rate of accuracy. Postoperative mortality and morbidity are lower in comparison with open lung biopsy. It is concluded that video-assisted thoracoscopic biopsy is an efficient and safe method in the diagnosis of chronic pleural effusion., Dugotrajni izljevi pleuralne šupljine zahtijevaju biopsiju pleure i pluća kod više od 60% bolesnika. Ranije se otvorena biopsija pluća smatrala najpouzdanijom dijagnostičkom metodom, dok se danas taj zahvat najčešće izvodi videotorakoskopskim putem. U zadnjih deset godina, od 1995. do 2005. godine, u Klinici za torakalnu kirurgiju "Jordanovac" operirano je videotorakoskopskim načinom 96 bolesnika u općoj anesteziji. Prosječna životna dob bila je 53 godine, s rasponom od 31-72 godina. Sve biopsije su rađene uzimanjem uzoraka hvataljkom s parijetalne ili visceralne pleure, a kod 31 bolesnika uzet je i komadić plućevine klinastom resekcijom uz pomoć endostaplera. Samo kod 12 bolesnika učinjena je konverzija u minitorakotomiju zbog opsežnih priraslica. Svi uzorci su upućeni na patohistološku analizu. Nakon zahvata svaki bolesnik je imao torakalni dren koji je spojen na negativni tlak. Histopatološka dijagnoza postavljena je kod gotovo svih bolesnika, tako da je uspješnost zahvata bila 97%. Kod 16 bolesnika postojao je produženi protok zraka na dren kroz više od pet dana, dok je prosječno vrijeme drenaže iznosilo 4 dana, a prosječni boravak u bolnici 8 dana. Kod većine bolesnika s malignim izljevom rađena je pleurodeza talkom kako bi prestalo nakupljanje izljeva. Videotorakoskopska biopsija omogućava uzimanje kvalitetnog uzorka pleure i plućevine (bioptata) uz visok postotak točnosti. Poslijeoperacijska smrtnost i pobol bili su niži nego kod otvorene biopsije pluća. Zaključak je da je videotorakoskopska biopsija pluća učinkovita i sigurna metoda u dijagnostici kroničnog pleuralnog izljeva.

Abstract

Deformiteti stijenke prsnog koša su relativno rijetke bolesti nepoznate etiologije koje se javljaju u djetinjstvu i adolescenciji. Primjetna je obiteljska pojavnost deformiteta uz vrlo rijetko spontano izlječenje. Kirurško liječenje predstavlja jedinu mogućnost ispravljanja deformiteta bilo klasičnim operacijskim načinom ili minimalno invazivnom metodom liječenja (endoskopskim putem). Među kirurzima nema ujednačenog stava o tome u kojem je životom razdoblju najbolje učiniti ispravljanje deformiteta, jer su rezultati vrlo dobri bez obzira na primijenjenu metodu liječenja. U ovom radu prikazani su rezultati liječenja kod 105 bolesnika operiranih klasičnim načinom između 1985. i 2005. godine u Klinici za torakalnu kirurgiju Kliničke bolnice za plućne bolesti „Jordanovac“., Chest wall deformities are relatively rare diseases of unknown etiology, which occur in childhood and adolescence. Pectus deformities show familial occurrence with very rare spontaneous resolution. Operative treatment is one of the possible therapeutic options for deformity correction by classic operative procedure or by minimally invasive method of treatment (endoscopic). There is no consensus among surgeons about the age at which correction of the chest wall deformity should best be performed because therapeutic results are very good irrespective of the method of treatment employed. Therapeutic results in 105 patients operated on by the classic method during the 1985-2005 period at University Department of Thoracic Surgery, Jordanovac University Hospital for Lung Diseases in Zagreb, Croatia, are reported.

Abstract

Descending necrotizing mediastinitis is a severe septic infection of the mediastinum, mostly resulting from an infectious process originating from the neck or oral cavity. The mortality rate associated with descending necrotizing mediastinitis remains high (>40%) in spite of the current medical and surgical treatment options. The disease may occur at any age and in either sex. Early diagnosis is of utmost importance to immediately initiate intensive antibiotic therapy or surgical intervention in case of the infectious process descent to the thoracic cavity. A patient with descending necrotizing mediastinitis, initially treated with antibiotic therapy followed by surgical intervention due to the disease propagation, is presented. Intraoperatively, a life threatening complication of the left venous angle erosion developed., Descendentni nekrotizirajući medijastinitis je ozbiljna gnojna infekcija medijastinuma koja najčešće nastaje spuštanjem infekta iz područja usne šupljine ili vrata. Smrtnost je i dalje vrlo visoka (preko 40%) usprkos današnjim mogućnostima liječenja konzervativnim ili kirurškim putem. Bolest se može pojaviti kod svih dobnih skupina, kako kod muškaraca tako i kod žena. U liječenju bolesti najvažnije je rano postavljanje dijagnoze kako bi se odmah započela intenzivna antibiotska terapija, a u slučaju spuštanja gnojnog procesa u prsni koš kirurška intervencija. Prikazuje se bolesnik s descendentnim nekrotizirajućim medijastinitisom koji je u početku liječen antibioticima, a zbog propagacije bolesti i kirurškim zahvatom. Tijekom kirurškog zahvata razvila se za život opasna komplikacija, erozija lijevostranog venskog spoja.

Abstract

The aim of the study was to establish the value of clinical preoperative staging of central bronchial carcinoma according to TNM classification (cTNM). Postoperative histopathologic staging of bronchial carcinoma according to TNM classification (pTNM) was used as a reference value. The study included patients with central non-small cell bronchial carcinoma. Preoperative staging was correctly assessed in 50%, underestimated in 32%, and overestimated in 18% of patients. The difference between preoperative and postoperative staging was not statistically significant. In order to be as precise as possible on preoperative bronchial carcinoma staging, all diagnostic methods available should be used to distinguish resectable from nonresectable tumors. The extent of diagnostic work-up should be coordinated with therapeutic consequences., U radu se vrednuje klinička prijeoperacijska procjena stadija centralnog karcinoma bronha prema klasifikaciji TNM (cTNM). Kao referentna vrijednost rabila se je poslijeoperacijska patohistološka procjena stadija karcinoma bronha prema klasifikaciji TNM (pTNM). Analizirani su operirani bolesnici s centralnim nemikrocelularnim karcinomom bronha. Prijeoperacijski je stadij bolesti bio točno procijenjen u 50,00%, podcijenjen u 2,00%, a precijenjen u 18,00% bolesnika. Razlika između prijeoperacijske i poslijeoperacijske procjene nije bila statistički značajna. Treba rabiti sve raspoložive dijagnostičke metode radi što točnijeg prijeoperacijskog određivanja stadija karcinoma bronha u cilju razdvajanja resektabilnih i neresektabilnih tumora. Opseg dijagnostike mora se uskladiti s terapijskim posljedicama.
