Studying anatomical characteristics and variants of prostatic artery on digital subtraction angiography

SUMMARY

Objectives: To describe anatomical features and variants of prostatic artery (PA) on digital subtraction angiography (DSA).

Subjects and Methods: Descriptive statistic study. We reviewed the DSA of 58 patients, which had a PA embolization to reduce the benign prostatic hyperplasia (BPH) symptoms at radiology department of Bach Mai Hospitalfrom Oct - 2016 to June - 2017

Results: PA was found at 110 pelvic halves, of which 5 pelvic halves (4,5%) had two PAs, 105 pelvic halves had one PA. In terms of the type of origin of PA according to Francisco Carnevalle, in 115 PAs, the percentage of type 1 (was from a common trunk with the superior vesical artery - SVA), type 2 (anterior division of internal iliac artery), type 3 (obturator artery), type 4 (internal pudendal artery), type 5 (less common origins)was successively 33,9%, 13,9%, 18,3%, 23,9%, 10,4%. Atherosclerosis of PA observed in 20.9%.The “corkscrew” patern was found in 30.4%. The average diameter of PA was 1.5 ± 0.34mm. Anastomosis of PA with surrounding arteriesare common. PA may supply rectum (6.1%), seminal vesical(9.6%), bladder (5,2%), controlateral prostatic parenhyma (13%), surrounding soft - tissues (3.5%).

Conclusion: The common trunk with SVA was the most common origin of PA. Anatomosis of PA with surrounding tissues is complex.... Therefore, profound knowledge ofthe PA anatomy and variants on DSA is necessary to treat BPH by prostatic arterial embolization.

Key words: prostatic artery, digital subtraction angiography, Francisco Carnevalle classification.

SUMMARY

A secondary postpartum hemorrhage may occur between 24 hours and 6 weeks after the birth. Secondary postpartum hemorrhage may be caused by endometritis, damage to an artery in caesarean, possible as a result of abscess from puerperal infection that causes damage to blood vessel. The urterine artery lesion is the most common, the internal pudental artery lesion is very rare. We report a case of a 36 year old patient, bleeding 12 days in postpartum due to damage to the internal pudendal artery, successful embolization of the internal pudendal artery.

Keyword: Secondary postpartum hemorrhage, embolization, uterine artery, internal pudendal artery.

Investigation of the relationship between rectocele and other pelvic floor disorders

SUMMARY

Background - Objectives: Pelvic floor dysfunction and prolapse are common condition of women past the middle age, with nonspecific clinical symptoms. Many cases of rectocele occurs combine with other pelvic floor disorders. Failure to recognize the complex set of pelvic floor defects leads to most therapy failures. The aim of this study is order to evaluate the correlations between age, number of birth and rectocele, and to define the role of dynamic magnetic resonance defecography in diagnosis.

Methods: Cross-study description. Patients with pelvic floor dysfunction had done clinical examinations and they were indicated dynamic MR Defecography at University Medical Center, HCM City by urologist or gynecologist and proctologist.

Results: MR Defecography of 1683 patients was evaluated from 01/2008 to 6/2012. Most patients are about 40 to 50 years old with 2 to 3 parity. 1218 patients with incontinence; 1311 patients (77.9%) has rectocele. Prolapse of the posterior compartment is the most common type of prolapse. Rectocele combines with more than one pelvic organ prolapse 77.4%; 64.2% of the patients with anismus had rectocele. There are statistically significant in the correlation of age, the number of birth with rectocele or pelvic organ prolapse (OR # 1.04-2.67 and p<0.005). Risk of rectocele was higher in the patients with pelvic organ prolapse than in the patients without pelvic organ prolapse (p<0.005).

Conclusions: Complex pelvic floor disorders often involve several compartments. Dynamic MR Defecography allows evaluating the both morphological and functional assessment of the pelvic floor, selecting the most appropriate treatment.

Value of magnetic resonance imaging in the diagnosis of ovarian thecomas/fibrothecomas

SUMMARY

Purpose: Our study aims to study the value of conventional magnetic resonance imaging (MRI) combined with DWI and Dynamic technique in the diagnosis of thecomas/fibrothecomas and differential diagnosis benign with malignant ovarian tumors.

Material and method: In total, 68 thecomas/fibrothecomas, 63 malignant ovarian tumors were included in our study. All patients underwent conventional MRI, DWI in 79 cases and Dynamic enhancement (DCE) in 14 cases. The clinical features and characteristics of conventional MRI, DWI and DCE of these two groups were analyzed. Apparent diffusion coefficient (ADC) values, Tmax, MRE were measured and compared between groups. Univariate analysis, multivariate logistic regression analysis were analyzed. Sensitivity (Se), Specificity (Sp), Positive Predictive Value (PPV), Negative Predictive Value (NPV) were included.

Results: All the fibromas/fibrothecomas showed hypo-isointensity on T1 weighted imaging (T1WI) and 77.9 % lesions showed hypo- to isointensity on T2 weighted imaging (T2WI). After administration of contrast medium, 82,3% tumors appeared as minor to mild enhancement, 71,4% benign tumor had type 1 curve, Tmax cutoff were 230s with Se and Sp 71,4%. MRE were not already measured because of few cases. On DWI, 68,4% fibromas/fibrothecomas manifested no signal intensity or low signal intensity. The ADC cutoff were 1.07 x 10-3 mm2/s to differentiate benign from malignant ovarian tumors. Multivariate logistic regression analysis showed that only T2WI and ADC were the important indicators in discriminating fibromas/fibrothecomas or benign tumors from malignant ovarian tumors.

Conclusion: The combination of DWI, DCE with conventional MRI is of great value in the diagnosis of fibromas/fibrothecomas and differentiation benign ovarian tumors from malignant ovarian tumors

Keywords: Fibromas/fibrothecomas, Conventional magnetic resonance imaging, Diffusion-weighted imaging, Apparent diffusion coefficient value, Dynamic contrast enhancement.

Investigation of hysterosalpingopraphy in infertile women

summa ry

Objectives: investigate the images of uterine cavity and fallopian tube patency by hysterosalpingopraphy in infertile women and learn the involved factors.

Subjects and methods: Cross-sectional descriptive study on 157 infertile women examined at Hue University Hospital with clinical examination, history and hysterosalpingopraphy.

Results: in 157 infertile women with mean-age 30.4 ± 5.4, there was 5.7% cases with abnormal uterine cavity and 13.4% abnormal tubal patency. In which, proximal blockage was 4.5%, distal blockage and hydrosalping were 8.9%. Some factors included age over 35 years (p = 0.02; OR = 2.49), secondary infertility (p=0.029; OR = 2.27), past history with tubal operation (p = 0.016) or high pressure of pushing fluid (p=0.004; OR = 4.005) associated with abnormal findings on hysterosalpingopraphy.

Conclusion: hysterosalpingopraphy helps detect many abnormalities in the uterine cavity and the fallopian tubes, especially in people over 35 year old, with a history of tubal surgery, secondary infertility. It is recommended to indicated hysterosalpingopraphy routinely for these cases for early detection of abnormalities.

Evaluation of changes in semen, sex hormones after intervention in varicocele

SUMMARY

Purpose: Evaluating the technical feasibility an semen quality after intervention of varicocele.

Subjects and research methods: Among 101 patients treated with varicocele emboization during 2 years. With 50 patients were followed up before and after embolization 6 months by the size of the vein, testes, and semen index including concentration, morphology, mobility, hormonal (including Testosterol, LH, FSH). Technical details, reasons for the failure of the procedure are noted. Using pairing comparison algorithm before and after treatment.

Results: 100% technical success. The indicators of spermatozoa including sperm concentration, morphology and mobility were improved with the reliability of 95%, especially sperm motility index, PR - sperm rised signigicantly with Z = 4,1 ± 1,51 (before and after treatment). The index of testosterol hormones increased significantly after treatment with Z = 1.81 ± 1.32, LH and TSH hormonal indexes did not change significantly.

Conclusion: Intervention of varicococele has been shown to be effective in improving semen and testosterone index.

Key word: Intervention of varicocele, Sperm, testosterone index.
