without previous thrombosis:

12 h) or LMWH in usual prophylactic
doses (i.e., enoxaparin 40 mg sc every
24 h).
with previous thrombosis:

usual therapeutic doses (i.e.,
enoxaparin 1 mg/kg sc every 12 h).
16. Heparin monitoring

Lab. Tip in monitoring:
prolonged aPTT should be investigated prior to initiating therapy.
For example, if the reason is a lupus anticoagulant
Routine monitoring of LMW heparin is not generally required.
18. Thrombo-(prophylaxis not therapy)
i.e : low-dose heparin
Route: subcutaneous tissue only (not muscle tissue).
Dosage: 5000 units every 8-12 hours.
Dose adjustment: aPTT or anti-Xa activity.
Injection sites should be rotated (usually left and right portions of the
abdomen, above iliac crest).

There is insufficient evidence to evaluate the effect of progesterone
supplementation in pregnancy to prevent a miscarriage in women
with recurrent miscarriage. B Green-top Guideline 2011

starting dose : 0.25 mg up to 0.5 mg two times a week.
Follow up :
PRL has to be controlled after 3 weeks of treatment
then; Do PRL level weekly
when PRL plasma levels are stabilized below 10 ng/ ml, cabergoline
dosage can be reduced to the minimum (i.e., 0.25 mg twice weekly).
In cases of hyperPRL rather than hypothroidism :
therapeutic effect of cabergoline in treatment of hyperprolactinemia
will typically persist for at least 4 weeks after cessation of treatment.

• Folliculo-endometrial asynchorony (increased endometrial thickness

65. no agreement has been reached on endometrial thickness. Although
most clinicians empirically prefer endometria >7 mm, available
evidence does not support any specific thickness, as pregnancies with

on pregnancy outcomes. (Kowalik et al Cochrane review 2011)
While :
elective hysteroscopic removal of the septum in asymptomatic patients
before the first pregnancy is not supported. (Parsanezhad et al; 2006)
81. Septate uterus by ESHRE–ESGE includes three morphological classes by ASRM; Top row,
norm (internal indentation ,1 cm); middle row, arcuate; and bottom row, septate uterus
83. Normal uterus by ASRM with the same length of internal fundal indentation in coronal view
(top row); may be recognized paradoxically by ESHRE-ESGE as a septate (case on left) or
normal uterus (case on right) depending on the thickness of the uterine wall in the sagittal
view (bottom row).

Remember
92. Post division ??
Immediately post procedure

3 months) unnecessary because division of the uterine septum does not lead
to formation of adhesions.

93. Should the Cervical Portion of the Septum Be Spared in
Patients with a Complete Septate Uterus?
Avoid secondary cervical incompetence.
Resection of the cervical portion was reported to make the procedure
safer, easier, and less complicated than preservation
of the cervical septum. (Parsanezhad et al; 2006)

if septate uterus is associated with mixed history
hysteroscopic metroplasty is of little value .

101. Intramural Myoma is associated with an increased risk of
spontaneous miscarriage [Ezzati et al; 2009].
Size ????
Before you do myomectomy complete evaluation evaluation has been
completed”. ASRM 2012
The location and size of the myomas are the two parameters that
influence the success of a future pregnancy. Kolankaya et al; 2006
BUT
102. Non surgical treatments :
• Drugs
• Embolization
• MRI US ablation
Has no role till now in mangment of myomas affecting
reproductive outcomes
104. Although the association between endometrial polyps and pregnancy
loss has not been proven, polyps are more common in patients with
recurrent spontaneous abortion. Valli et al; 2001
Surgical excision is usually recommended, Devi et al; 2006
105. Hysteroscopic polypectomy can be performed by excision with
forceps or gentle curettage.
While resectoscope had a 0% recurrence rate and that
grasping forceps had a 15% recurrence rate. Preutthipan et al; 2005
If endometrial polyp less than 1.5 cm try 1st synthetic progestagens
106. Cervical insufficiency

109. Funnel length should not be measured or recorded as it is not an independent predictor of
preterm labor risk when the closed length of the cervical canal is considered
110. Evaluation of cervical length in a patient with a curved cervix. If the widest distance (A, red

17-alpha-hydroxyprogesterone (17P) FDA approved march 2011 for
prevention of PTL and mid Trimesteric abortion
Safe drug by numerous
epidemiologic studies (Schardein

trials ( Meis et al; 2003 -Fonseca et al;
2003 - O'Brien et al; 2007)
118. Risk of hypospadias in male offspring exposed to exogenous
progestins; even if confirmed, this risk is limited to exposure prior to
11 weeks of gestation and thus is not relevant to women with
prior preterm delivery, as they will receive the drug after 16
weeks of gestation [Silver et al; 1996 – Carmichael et al; 2005 ].
Treatment-genotype interactions, which could
result in either a beneficial or harmful treatment response [Manuck et
al; 2011 ].
123. According to probability theory, at least 50% of embryos created by a
parent with a balanced translocation and 67% of embryos created by
a parent with a Robertsonian translocation will be abnormal
At least one euploid embryo was identified in 61% of initiated IVF
cycles, and in 79% of cycles in which PGS was performed.
124. Extraordinary genetic diversity of the
human embryos at implantation
That put another question about the
value of PGS before embryo transfer
??!!!
Is it a help or a hype
125. FISH Vs CGH
Comparative genomic hybridization (CGH) is a
genetic test that identifies all chromosomes
within the embryo , not as FISH which detect
defects in some individualized chromosomes
،السبت02،رمضان1438
126. PGS is notan indicative marker for embryo quality, but a definite genetic
diagnostic test to excludedevelopmentally incompetent embryos from the
cohort, those that are at risk to generate miscarriage or implantation failures
127. trophectoderm biopsy (Scott et al., 2013) and vitrification do
not compromise the reproductive competence of blastocysts
(Schoolcraft et al., 2011).
Morphological criteria, even coupled with morphokinetic analysis, are
very poor predictors of embryo chromosomal
architecture and viability (Capalbo et al., 2014; Rienzi et al., 2015).
So
Poor-quality blastocysts have significant euploidy rate and considerable
delivery potential (Capalbo et al., 2014); poor embryo quality should
not be used as a reason to cancel the genetic-testing procedure when
PGS has been indicated before starting the IVF cycle.
128. TTT :
just Genetic counseling
Financial cost as well as implantation and live birth rates per
cycle following in vitro fertilisation/ preimplantation genetic
diagnosis.
They should be informed that they have a higher (50–70%)
chance of a healthy live birth in future untreated pregnancies
following natural conception Franssen et al; 2006 than is
currently achieved after preimplantation genetic diagnosis/in vitro
fertilisation (approximately 30%). Lalioti 2008
129. Indicated only in :
women of advanced reproductive age with RPL:
• There is no evidence that IVF with PGS improves
overall live birth rates compared with expectant
management, because a significant number of IVF cycles
either do not undergo PGS or fail to identify euploid
embryos.
However, when euploid embryos are identified in women
older than age 35, the live birth rate is improved.
130. Observational studies have shown that increased consumption of folic
acid in the periconceptional period may reduce this risk. George et al;
2002 – Gaskins et al; 2014
132. A review of all published large RCTs and metaanalyses
undertaken by the ESHRE Special Interest Group for Early
Pregnancy (SIGEP) protocol for the investigation and medical
management of recurrent miscarriage concluded that the only
interventions that do not require more randomized controlled
trials are tender loving care and health advice.

137. • Avoidance of toxicities such as smoking, hot tubs/saunas, etc.
• Antioxidant vitamin supplements may reduce sperm DNA damage
(we have published reports of this benefit).
• Encourage the patient to eat food rich in antioxidants (fruit, veg,
dried tomatoes etc)
• Treatment of infection may reduce sperm DNA damage.
• Varicolectomy may reduce sperm damage. TESE (testicular
extraction of sperm) has been proposed as being beneficial (we
recommend it in some cases).
• Decreased abstinence days to only one day !!! Isabel et al; 2013.
Treatments for elevated sperm DNA fragmentation include:
Cause specific treatment :
138.
139. To conclude, the findings of this systematic review demonstrate a
significant relationship between levels of DNA damage in sperm and
spontaneous pregnancy loss
Tests for DNA damage and selection of undamaged sperm should be
considered as part of the diagnostic and treatment pathways for those
suffering from recurrent pregnancy loss
140. Does we have an overlap between
RPL and infertility ??!!!
To consider in treatment
141.
142. Take home message
If the treatment of RPL is not cause specific treatment consider
