Balloon Embolization

PurposeTo investigate the effects of detachable balloons in embolizing traumatic carotid cavernous fistulas (TCCFs) and the risk factors for recurrence after balloon embolization.Materials and methods188 patients with TCCFs were enrolled, and clinical, treatment, and follow-up data were analyzed for possible risk factors for recurrence after embolization.ResultsAmong 188 patients, 182 (96.8%) had successful balloon embolization; 6 patients failed. One balloon was used in 94 cases and multiple (two or more) balloons were used in 62 patients. 26 patients had occlusion of the parent artery whereas the remainder had parent artery preservation. Periprocedural complications occurred in 3 patients (1.6%) including cerebral embolism in 1 and abducent nerve paralysis in the other 2. Immediately following embolization, headache appeared in 92 patients and was relieved after 3–5 days with medications. A total of 165 patients (87.8%) had follow-up (6 months to 16 years, mean 5 years). 23 (13.9%) patients with internal carotid artery preservation had recurrence 1–33 days (mean 11 days) after the first embolization and were retreated to complete occlusion. Factors affecting recurrence were multiple balloons and residual fistula (p<0.05). Logistic regression confirmed the independent factors affecting recurrence were multiple balloons (≥2 balloons, OR 7.80, 95% CI 2.28 to 26.73; p=0.001) and residual fistula immediately following embolization (OR 10.46, 95% CI 2.99 to 36.5; p=0.000).ConclusionThe recurrence rate is high in the first month after embolization with detachable balloons, and multiple balloons and residual fistula are two independent factors affecting recurrence following balloon embolization.

1. The thyroids of the adult Californian newt, Triturus torosus, were examined in Zenker, Champy, and Nassonov preparations, in one series in which these glands were entirely at rest, in another series in which they underwent a spontaneous activation and in a third group in which activation had been forced by intraperitoneal injections of thyroid activator. 2. As in invertebrates so in the newt the Golgi apparatus appears to consist of two components, of one which is deeply blackened, and of another one which stains much darker than the cytoplasm and corresponds to Bowen's idiosomatic substance. The former frequently forms a shell around the latter as a core. The problem has been discussed in the light of the work published recently by Owen and Bensley. 3. Only incomplete observations are available concerning a possible relation between Golgi apparatus and functional phase of the cell. (a) In the resting condition the Golgi apparatus is relatively small and compressed in an apico-basal direction. (b) In preparation for colloid release through the basal cellends, the Golgi apparatus enlarges greatly in an apico-basal direction and its trabeculae become stout. (c) In the cells in which fluid has accumulated in large lacunae and is excreted through the basal cell-ends, the Golgi apparatus begins to become fragmented into long, slender pieces. (d) In the cells in which basal excretion has ceased and the remaining liquid has been condensed into stainable droplets, the fragments are transformed into short, thick, and lumpy pieces. (e) When the colloid droplets are redissolved and transformed into vacuoles for the purpose of refilling the follicles, the Golgi bodies appear as black rings around a dark core. 4. In most instances the topographical relation existing between the Golgi apparatus and the secretion products is not specific. The distribution of the Golgi material represents merely an accurate repetition of the distribution of the cytoplasm. 5. In some instances, however, a close relationship is found between the Golgi apparatus and the secretion products (figs.12-15, 22, 23, PI. 36). 6. In no case does the Golgi apparatus show a reversal of its position from the apex to the base of the cell. In cells which are in an active state of basal excretion the Golgi apparatus may be strictly apical. Its position does not convey a knowledge of the excretion polarity of the cell.

Abstract Context.—Recently, prostatic atrophy associated with chronic inflammation has been linked to carcinoma either directly or indirectly by first developing into high-grade prostatic intraepithelial neoplasia. Objective.—The purpose of our study was to test this hypothesis in autopsies. Design.—A step section method was used to cut the posterior lobe in coronal planes at intervals of 0.3 to 0.5 cm in 100 consecutive autopsies of men older than 40 years. Prostatic atrophy was classified as simple, hyperplastic (or postatrophic hyperplasia), and sclerotic and was analyzed for the presence of chronic inflammation. Prostatic atrophy without (group A) and with inflammation (group B) was correlated with the following variables: age, race, histologic (incidental) carcinoma, high-grade prostatic intraepithelial neoplasia, and extent of both these lesions. Results.—Of the 100 prostates examined, 12%, 22% and 66%, respectively, had no atrophy, atrophy without inflammation (group A), and atrophy with inflammation (group B). There was no statistically significant difference between groups A and B for age (P = .55), race (P = .89), presence of histologic (incidental) carcinoma (P = .89), extensive carcinoma (P = .43), presence of high-grade prostatic intraepithelial neoplasia (P = .65), extensive high-grade intraepithelial neoplasia (P = .30), or subtypes of prostatic atrophy. Neither a topographical relation nor a morphologic transition was seen between prostatic atrophy and histologic carcinoma or high-grade intraepithelial neoplasia. Sclerotic atrophy either alone or combined with other subtypes was more frequent in the group with inflammation. A striking morphologic finding was a topographical relation of focal inflammation with sclerotic atrophy in areas with erosion of the epithelium. Conclusions.—Inflammatory prostatic atrophy does not appear to be associated with histologic (incidental) carcinoma or high-grade intraepithelial neoplasia. One possible cause of inflammatory infiltrate associated with prostatic atrophy may be the extravasated prostatic secretions, which were noted in areas of eroded epithelium, a common finding in the sclerotic type of prostatic atrophy.
