POSTOPERATIVE ARTERIAL RELAXATION AND INTRAOPERATIVE VENOUS DILATION AS INTERCONNECTED PROGNOSTIC FACTORS FOR THE MATURATION OF ARTERIOVENOUS FISTULAS.

AIM: To investigate if immediate arterial distention can be used as a predictive factor for the development of a good fistula. MATERIAL AND METHODS: Over a 5-months period (January- May 2015) all the patients who underwent an arteriovenous fistula between the radial artery and the cephalic vein of the forearm at the Second Surgical Clinic of the Iasi Regional Cancer Institute and were willing to participate were enrolled in the study. The diameters of the vessels were measured 1 hour and 8 weeks after surgery. RESULTS: We found statistically significant differences for all measured diameter variations between the calcified artery and normal artery groups (p < 0.001 for the arterial distention at 1 hour and 8 weeks after surgery and p = 0.002 for the venous distention 8 weeks after surgery). A linear regression also showed that the degree of arterial distention immediately after surgery and the venous distention 8 weeks after surgery were statistically correlated. CONCLUSIONS: Arterial distention immediately after surgery and therefore the lack of it due to the presence of arterial calcifications can be used to predict whether or not a good fistula can be achieved at a 1% statistical significance level.

Epidemiological evaluation of the outcomes after video-assisted thoracoscopic talcage in neoplastic pleurisy.

AIM: Clinical-epidemiological investigations for further assessing the importance of video-assisted thoracoscopy in the treatment y of patients with neoplastic pleurisy. MATERIALS AND METHODS: The researches included a group of 72 patients (31.9% men and 68.1% women aged 31-81 years, mean age ± 60 years) with neoplastic pleurisy who underwent pleural symphysis by video-assisted thoracoscopic talcage. For statistical-mathematical processing and interpretation the Pearson correlation index with the level of significance at p = 0.05 and highly significant at p < 0.005 was used. RESULTS: Neoplastic pleurisy prevalently affected the age groups 51-80 years (84.9%). Dyspnea was present in all cases, and patient history at the time of admission revealed 14 conditions, of which 25% were lung cancers. Macroscopically nodular and vegetative tumors were found in 66.7% of cases. An amount of 1000-2000 ml of pleural fluid was found in 44.5% of the cases and a serocitrin appearance in 50%. In 23.6% of the cases cytology results were positive for malignancy and in 13.8% suspicious. In 65.2% of the cases the pleural fluid was exudative and anatomopathology was suggestive of adenocarcinoma in 34.7% of the cases and breast cancer in 18%. The prevalence of recurrences varied from 1 month to more than 7 months, with 36.4% for 1-2 months. CONCLUSIONS: The obtained additional data support the important role of pleural symphysis by video-assisted thoracoscopic talcage in the patients with neoplastic pleurisy.

[True posttraumatic femoral artery aneurysm: a rare clinical entity]. / Anevrism adevarat posttraumatic de artera femurala. Entitate clinica rara.

Traumatic etiology in aneurysms is very rare. After arterial trauma we usually find pseudo aneurysms. True aneurysms are due to deterioration of the arterial wall in small and long-term repetitive trauma. Pseudo aneurysms are usually described on radial and cubital artery in patients who work with vibrating tools ("hypothenar and thenar hammer syndrome") and on axilar artery in those who use axilar crutches. We present a case of a woman with a true aneurysm of the femoral artery developed due to repetitive trauma of the femoral region at the work place. The patient presented as an emergency, with ruptured aneurysm and she underwent an emergency operation. The diagnosis was established late by histopathological examination. This is the first case of posttraumatic true aneurysm with this location. True aneurysms should be considered in repetitive trauma regardless of anatomical region.
