[THE ROLE AND PLACE OF VIRTUAL CT COLONOSCOPY IN COMPLEX RADIOLOGICAL DIAGNOSIS OF COLON DISEASES].

Nowadays CT colonoscopy is one of the basic methods for colon disease diagnostic. In Georgia mentioned method is used rarely despite of its high diagnostic potential. The current research aims to populate CT colonoscopy to be widely used in diagnostic as well as preventive healthcare, develop radiological semiotics of colon specifications and pathology changes. The research have been carried out in Batumi Referral Hospital. During the clinical researches patient's complains were gathered in details , also there was considered life , medical history and clinical research data. Following instrumental methods were used: CT colonoscopy, fibrocolonoscopy, irrigography-irrigoscopy, ultrasound research of colon. Computer Tomography researches was carried out on "General Electric" (USA) 16 layer CT scanner with 1.2 mm step by following phases: definition of research indication, preparation of intestine, insufflation, getting image, working on image and interpretation. In all cases intenstine was filled up with common air by manually method. According to 224 patients examination results in colon growing anomalies diagnostic CT colonoscopy responsivity is 98,0%, specificity 100%, diagnostic accuracy 98,2%, diverticulosis diagnostic 92,3%, 95,1%, 92,7%, and accordingly polyps in diagnostic: 87,3%, 85,6%, 85,9%. According to the gained results we can make conclusion, that CT colonoscopy is a reliable, high informational and minimally invasive diagnostic method to discover pathological disorder in colon wall and early stage cancer.

PARTIAL ANOMALOUS PULMONARY VENOUS CONNECTION WITH INTACT ATRIAL SEPTUM: A CASE REPORT.

Partial anomalous pulmonary venous connection (PAPVC) is a type of left to right shunt, when one or more lung veins drain to right atrium directly or indirectly via systemic veins. PAPVC is a rare condition, discovered by 0.4 to 0.7% of cases in autopsy series. It is often associated with atrial septal defect, but can be found with other congenital anomalies such as ventricular septal defect. Our report is about 42-year old woman who has right sided PAPVC draining into right brachiocephalic vein, which was incidental finding during pulmonary CT angiography. Patient had no symptoms associated with PAPVC and had no accompanied congenital anomaly, which is more rare condition. After consultations by surgeons, decision of conservative follow up was made, because of the fact that patient was asymptomatic. After performed multidetector computed tomography and image analysis in coronal, sagital and 3D reconstructions gave us superior quality images for data analysis. Once more, it confirms the role of modern high quality computed tomography in the diagnostic abilities of PAPVC.

Clinical manifestation and management of intravenous mercury injection: a case report.

Intentional self-injection of metallic mercury case report is presented. A 22 year old man with a past medical history of ethylene glycol suicidal poisoning was admitted to a Acad. N. Kipshidze Central University Clinic in Tbilisi, four months after deliberate intravenous injection of an unknown quantity of metallic mercury from several thermometers into his antecubital vein. After 2 months of asymptomatic period, the patient began to complain of pain and tremor in limbs, fatigue and skin rash. CT scan of the thorax and the abdomen confirmed multiple small opacities of metallic density in both lungs, liver and right kidney. After the procedure the patient was transferred to the toxicology center in Baku, Azerbaijan for chelation therapy. On arrival no biochemical abnormalities in hepatic or renal function or clinical pulmonary malfunction were detected, despite presence of slight symptoms of erethism, tremor mercuralis, knee joints arthralgia and lower extremities weakness. Chelation therapy with intramuscular injection of Unithiol (DMPS) was started in dose of 20mg/kg/day. After one month of chelation therapy, mercury blood concentration slowly decreased from initially 134 microgram/L to 105 microgram/L. This case report demonstrates mild acute toxicity following intravenous administration of unknown amounts of elemental mercury. Because of chelation therapy can remove approximately 1 mg of mercury per day the patient was recommended further long-term DMPS treatments under the control blood mercury levels. It is concluded that clinical manifestations of intravenous elemental mercury intoxication may be delayed despite significant increase in blood mercury level.

The role of multislice spiral computed tomography in the diagnosis and management of acute facial trauma in patients with multiple injuries.

Using of mutislice spiral CT as first line examination for the diagnosis of Acute Facial trauma in the setting of Polytrauma reduces both: valuable time and cost of patient treatment. After a brief clinical examination, MDCT was performed depending on the area of injury, using a slice thickness of 0.65 mm. The obtained data were analyzed using 3D, MIP and Standard axial with Bone reconstruction protocols. 64 polytrauma patients were evaluated with both Anterior and Lateral craniography (plain skull X ray: AP and Lateral) and Multi Slice CT. Craniography detected only 18 cases of traumatic injuries of facial bones, but exact range of dislocation and accurate management plan could not be established. In the same 64 cases, Multislice CT revealed localization of all existed fractures, range of fragment dislocation, soft tissue damage and status of Paranasal sinus in 62 cases (96.8%). In two cases MS CT missed the facial fracture, in one case the examination was complicated because of bone thinness and numerous fracture fragments, in another multiple foreign body artifacts complicated the investigation. The study results show that, CT investigation based on our MDCT polytrauma protocol, detects all more or less serious facial bone injuries.

[Role of multislice spiral computed tomography in diagnosis of spinal injuries in polytrauma patients].

Spinal injury in poly trauma patients is serious problem, because they cause high mortality and morbidity. According to WHO statistics, there are registered 30 million cases of spinal injuries annually, 50% of them die before reaching the hospital. In last 5 years incidence of spinal traumas has increased 2.6 fold and is about one third of all spinal diseases. That is why spinal injuries remain a challenge. The purpose of our study is to assess diagnostic efficiency of multislice spiral CT in diagnosis of spinal injuries in poly trauma patients. We randomly assessed data from 200 poly trauma patients, who underwent multislice spiral CT in poly trauma mode. In 92 (46%) patients different types of spinal fractures and injuries were detected. Age distribution was 16-72 (mean age 52 years). Out of 92 patients, 9 (4.5%) had isolated trauma, 83 (41.5%) had multiple trauma. Solitary injury of spinal column was detected in 30 (32.6%) patients, 54 (58.6%) had combined spinal injuries. In spinal injury patients the most common trauma mechanism was MVC - 56 patients (60.86%), fall from height 27 (29.36%) patients, diving 5 (5.43%) patients, gun shot wound 3 (3.26%) patients, industrial injury 1 (1.08%) patients. The most common location of the injury was lumbar vertebra (55 patients), thoracic vertebra (39 patients), cervical vertebra (28 patients). After assessing MDCT and MRI results 37 patients were operated, 6 of them underwent surgical intervention urgently, 31 had delayed surgery, that was performed after treating other life threatening injuries. Indications for surgical intervention were spinal cord compression and non stable vertebral fractures. According to our study results, MDCT is the study of choice for the diagnosis of spinal injuries in poly trauma patients. It helps to detect type and extension of the bony injury and visualize fragments in the spinal canal. It is superior to other radiological studies. 3D, MIP and MPR reconstruction gives information about spatial location of the fracture and helps to timely plan correct management.

[Diagnostic possibilities of multilayer computer tomography in blunt abdominal trauma].

The purpose of our study was to determine MDCT diagnostic possibility in blunt abdominal trauma. Our work was based on MDCT results of 84 blunt abdominal trauma patients with stable hemodynamic status (28 (33.3%) female and 56 (66.6%) male). Age ranges from 17 up to 64 years. The CT scan showed obvious organ and system injuries in 82 poly-trauma patients. Injuries of craniocerebral region, also of facial bones, chest and spine were determined in two patients; in one of which, however, it was not possible to differentiate subcapsular spleen hematoma accurately because of left upper joint metallic holder artifacts. In second patient the liver injury was accurately diagnosed, but there were visualization problems caused by the massive retroperitoneal hematoma from right adrenal gland injury. The investigation showed that sensitivity of CT scan data was 98%, specificity-97% and accuracy rate-98%. All above mentioned clearly states the importance of MDCT in the emergency department. MDCT ensures precise diagnosis in maximally short period of time and thereby helps to choose proper treatment and decreases post-traumatic complications.

[The role and place of helical ct for preporative diagnosis of acute appendicitis].

The goal of our study was to ascertain the role and place of helical CT for preoperative diagnosis of acute appendicitis. Our study relied upon the results of helical CT scans of 60 patients, which were diagnosed probable acute appendicitis based upon clinical signs. Of these 60 patients 49 (81,6%) were female, 11 (18,4%) male. For all patients laboratory studies of blood were made, 31 patients were examined by ultrasonography. Among this group the diagnosis of acute appendicitis was verified by CT scan in 41 patients. In the case of 5 patients the scan was equivocal because of smaller amount of omentum; in this subgroup of 5 patients (5% overall) three were given radiocontrast dye, and two (3,3% overall) were not. In 11 (18,3%) cases the diagnosis of acute appendicitis was not verified, and in three cases the diagnosis was incorrect. According to data of our study and intraoperative data analysis, sensitivity of this method approaches 93% and the specificity - 92%, and overall diagnostic accuracy 93%. Helical CT may be stated as diagnostic method of choice in the diagnosis of acute appendicitis. It is helpful in clinical decision making, and reducing the amount of false appendectomies.

Endovascular treatment of stenosis of autogenous arteriovenous access for hemodialysis.

Retrospectively review of long-term outcome of balloon angioplasty (TBA) in the treatment of native dialysis A-V fistulae stenosis was conducted. From February 2008 to January 2009, seven hemodialysis patients (5 women and 2 men; mean age 46.4 years) were treated for stenosis of the A-V fistula at the venous outflow tract. Angioplasty was performed with the use of high-pressure balloons. Percutaneous transluminal angioplasty was used. There were no any complications during and after procedure. In 4 cases residual stenosis did not exceed 10% and in 3 cases 30%. After 3 month the improvement rate was 85%. Two patients required surgical treatment. None of the patients displayed any major complications from the procedure. This study confirms the efficacy of PTA in the treatment of vascular access stenosis. Elevated dialysis blood line pressure can be the first sign of fistula stenosis. Although our series is small, we have nevertheless demonstrated that the concerted efforts of nephrologists, interventional radiologists, and surgeons are the key to maintaining and prolonging vascular access survival in this group of patients.
