How to diagnose splenic abscesses?

Splenic abscess is a rare but potentially fatal entity, occurring mainly in patients with underlying risk factors. Mortality of the disease depends on the time of diagnosis and treatment. Due to low sensitivity and specificity of clinical symptoms and laboratory markers, imaging plays the vital role in the diagnostic work-up. The aim of this article is to give a concise overview of the methods of splenic abscess diagnosis.

High-frequency ultrasound-based differentiation between nodular dermal filler deposits and foreign body granulomas.

BACKGROUND: The number of procedures involving dermal filler injection is still on the rise. Although their safety is improving, not all complications can be avoided. The late complications manifesting as nodules or granulomas pose a particular diagnostic and therapeutic challenge, due to the lack of uniform standards or guidelines. High-frequency, ultrasound imaging appears to be a useful method for distinguishing between granulomas and nodular dermal filler deposits. AIM: The aim of the paper was to evaluate the utility of high frequency ultrasound imaging for distinguishing between foreign body granulomas and nodular dermal filler deposits. MATERIAL AND METHODS: Eleven females aged 21-66 years (mean age of 43.6 years old) who had soft tissue fillers injected were enrolled. All patients had a high-frequency ultrasound scan of the involved skin area performed. The shape, margins, area, location and echogenicity of the lesions were assessed. Additionally, the lesions were evaluated histologically and photographs were taken. RESULTS: The analysis indicated differences between the ultrasound image of granulomas and dermal filler deposits. Characteristic ultrasound features of granulomas include oval shape and blurred, irregular outer edges. Small hyperechoic areas were seen inside the granulomas. The deposits were anechogenic, with sharp, regular borders. CONCLUSIONS: High-frequency ultrasound imaging enables distinguishing between granulomas and nodules-dermal filler deposits, which form after dermal filler injections.

The use of a novel method of endovenous steam ablation in treatment of great saphenous vein insufficiency: own experiences.

OBJECTIVE: Endovascular procedures are gaining more and more popularity as treatment of great saphenous vein (GSV) incompetence. The purpose of the present study was to assess the efficacy of steam GSV ablation. METHODS: Steam ablation using the steam vein sclerosis system (CERMA, France) was performed in 20 patients with GSV incompetence. The efficacy of the procedure was evaluated using ultrasound and the following parameters were assessed: changes in lumen diameter, GSV wall thickness, reflux and presence/absence of blood flow. RESULTS: The GSV steam ablation resulted in the obliteration of the vein lumen in all patients - reflux or blood flow were not observed in any subject. A significant decrease of GSV lumen diameter and an increase of GSV wall thickness were also observed in all subjects following the procedure. No postoperative complications were noted. The steam ablation technique was also positively assessed by the patients. CONCLUSIONS: Steam ablation is an endovascular surgical technique, which can become popular and widely used due to its efficacy and safety. It is also easy to use and patient-friendly. The research on its use should be continued.

The effectiveness of anticellulite treatment using tripolar radiofrequency monitored by classic and high-frequency ultrasound.

BACKGROUND: Cellulite affects nearly 85% of the female population. Given the size of the phenomenon, we are continuously looking for effective ways to reduce cellulite. Reliable monitoring of anticellulite treatment remains a problem. OBJECTIVE: The main aim of the study was to evaluate the effectiveness of anticellulite treatment carried out using radiofrequency (RF), which was monitored by classical and high-frequency ultrasound. METHODS: Twenty-eight women underwent anticellulite treatment using RF, 17 women were in the placebo group. The therapy was monitored by classical and high-frequency ultrasound. The examinations evaluated the thickness of the epidermal echo, dermis thickness, dermis echogenicity, the length of the subcutaneous tissue bands growing into the dermis, the presence or absence of oedema, the thickness of subcutaneous tissue as well as thigh circumference and the stage of cellulite (according to the Nürnberger-Müller scale). RESULTS: Cellulite was reduced in 89.286% of the women who underwent RF treatment. After the therapy, the following observations were made: a decrease in the thickness of the dermis and subcutaneous tissue, an increase in echogenicity reflecting on the increase in the number of collagen fibres, decreased subcutaneous tissue growing into bands in the dermis, and the reduction of oedema. In the placebo group, no statistically significant changes of the above parameters were observed. CONCLUSION: Radiofrequency enables cellulite reduction. A crucial aspect is proper monitoring of the progress of such therapy, which ultrasound allows.

The removal of post-sclerotherapy pigmentation following sclerotherapy alone or in combination with crossectomy.

BACKGROUND: Sclerotherapy is a widely used method for the obliteration of blood vessels. Hyperpigmentation is a frequent complication that results from haemosiderin (FeO) accumulation. Hyperpigmentation and changes in the skin can be observed with ultrasound. OBJECTIVE: The aim of this study was to evaluate the efficacy of hyperpigmentation elimination using an intense pulse light generator (IPL) equipped with radio waves (RF) under ultrasonography (US) control. METHODS: Twenty-one women with permanent hyperpigmentation (after sclerotherapy or crossectomy combined with sclerotherapy) underwent a hyperpigmentation eliminating therapy with the use of IPL + RF and were monitored by using US. The thicknesses of the dermis and the subcutaneous tissue as well as the echogenicities of each layer were assessed. RESULTS: As a result of the therapy, a complete regression of hyperpigmentation was achieved in 90.48% of the women, and in 9.52% of the women, the therapy led to a reduction in hyperpigmentation but did not cause its complete disappearance. An increase in dermal echogenicity and a decrease in subcutaneous tissue echogenicity were observed, but there was no change in their thicknesses. After the therapy, the ultrasound images of areas of previous hyperpigmentation corresponded with images that were characteristic of healthy skin. CONCLUSION: IPL + RF therapy is effective for eliminating permanent skin hyperpigmentation after sclerotherapy. US is also useful in this therapeutic method.

Splenic arteriovenous fistula--late complications of splenectomy.

This is a case report of a 30-year-old female patient with a splenic arteriovenous fistula of rare, atypical clinical course. The patient was admitted to the hospital due to strong abdominal pains and fever. 13 years earlier, the patient underwent splenectomy due to post-traumatic rupture of the spleen. On imaging examinations prior to surgery (ultrasonography, CT), a splenic arteriovenous fistula was diagnosed. The patient was operated on due to increasing abdominal pain. The fistula was closed by splenic artery and splenic vein banding during the course of laparotomy. This case report will be discussed based on literature review.
