Ectopic pregnancy management (Conservative, Medical and Surgical Management)
CONSERVATIVE MANAGEMENT - rarely done
-Only if No or very minimal symptoms
-Adnexal mass < 35mm
-No visible heartbeat
-The ectopic needs to be unruptured
-HCG level < 1500 IU / l
-Close follow up required, if b-hcg is not going down then active management
MEDICAL MANAGEMENT
One of dose of IM methotrexate in bum
Criteria: low hcg, ability to attend follow up,
adherence to avoiding pregnancy for 3 months following treatment
same as conservative essentially except: HCG level must be < 5000 IU / l
If first dose doesn’t work give second or surgical management
SURGICAL MANAGEMENT (MAJORITY OF PATIENTS)
Recommend in cases where patients are unable to attend follow-up, the ectopic pregnancy is advanced or the patient is haemodynamically unstable.
1st line laproscopic salpingectomy
Surgical management often involves removing that tube, unless the patient only has one functioning tube and wishes to remain fertile. In that case is salpingotomy may be performed where only the ectopic pregnancies removed. However, there is a risk that all the tissue will be removed and so the beta CG needs to be performed to exclude any remaining trophoblastic tissue within the Fallopian tube.

What is the management of Aortic stenosis?
Management
- if asymptomatic then observe the patient is a general rule
- if symptomatic then valve replacement
- if asymptomatic but valvular gradient > 40 mmHg and with features such as left ventricular systolic dysfunction then consider surgery

Aortic regurgitation
Pulmonary fibrosis vs Bronchiectasis?
Bronchiectasis- permanent dilation of the bronchi causing sputum and organisms to drown leading to chronic PRODUCTIVE cough and recurrent infections, HAEMOPTYSIS

TAVI vs Open heart surgery. which is preffered when?
Transcatheter Aortic Valve Implantation
Long-term outcomes for TAVI still need to be clarified as it is a relatively new procedure. Therefore, open surgery is still the first-line option in younger, fitter patients.
Patients with a TAVI do not typically require warfarin as the valve is bioprosthetic.
