my dads surgery

Hi all, well my dad had his surgery on the 16/3, they only removed a portion of his kidney which we were all happy about he looked really good, unfortunatley that didnt last, he left high dependancy after 5 days and went into a normal surgical ward and he started having problems breathing, they did test and found both of his bottom lungs had collapsed and they did a ct angeogram at 11 sunday night, but "couldnt" actaully say for sure whether there was a blot clot, they suspect there is, so they are treating him for that. The last few days he has had alot of breathing problems and that is making him anxious . Ill post more when i can.
