CT contrast for dx
NBM, NG, IV fluids, endoscopic decompression, flexi sig +/- surg
Gallstones Ix and outcomes of these

Half of this is given in first 8 hours
occlusion in distal aorta-thigh/bum claudication + absent fem pulse, male impotence
Leriche syndrome
Normal ABPI
0.9-1.3 = N
0.6-0.9 = Mild PAD
0.3-0.6 = Mod-severe PAD

> 3cm
US - 65 for Dx, CT in stable pts with symptoms for repair
3-4.4 = yearly follow up
4.5-5.4 = 3m follow up
5.5+. symptoms/ 1cm+ growth in a year = repair

aortic stenosis
What congenital problem is coarctation of aorta ass with
turner syndrome
Pneumothorax mx
No SOB, <2cm = follow up 2-4 weeks

Breast cancer surgery - no palp LNs in axilla vs palpable Las in axilla
Prior to surg:
No palp LNS in axilla - pre op axillary US. If + then sentinel node biopsy
Palp LNs - axillary node clearance at surg 9can give arm lymphoedema etx)
