Description
The ones that reach the ward
If you work in a hospital that performs intervention but you are not the operator, this is the more relevant half of the book. Retroperitoneal haemorrhage, contrast nephropathy, late tamponade, pseudoaneurysm, subacute stent thrombosis — all of them present on a ward, hours after the procedure, to whoever is covering.
That doctor was not in the laboratory and does not know what was technically difficult about the case. They are nonetheless the person who has to notice.
Recognition before management
Each complication is written recognition first: what the patient looks like, what the observations do, and how long after the procedure it typically declares. Management follows as an action sequence. The commonest failure is not treating these badly — it is attributing a quiet tachycardia to pain or anxiety for six hours.
The in-lab half
Perforation graded by severity, abrupt closure, dissection, arrhythmia, equipment entrapment and no-reflow, each as an ordered response.
Relevant to
Interventional operators, but equally ward physicians, intensivists, emergency clinicians and nursing staff in units that receive post-procedure patients — a much larger group than the operators, and the one that usually has to make the call.

The complications that announce themselves, and the ones that do not
Cath lab complications divide into the open and the hidden, and the hidden ones cause most of the harm. Perforation recognised late, retroperitoneal bleeding presenting as agitation, air embolism, dissection propagating quietly, contrast nephropathy declared only on the ward — each is given its earliest sign rather than its classical description.
Written for the operator on the day it happens
Management is sequenced as it must be performed, with equipment named, thresholds stated and the decision to stop or continue addressed directly. Prevention is treated as a laboratory culture question — access technique, anticoagulation checks, contrast discipline, the second operator’s role — rather than a list of exhortations. A closing section covers disclosure, documentation and the morbidity meeting, which is where cath lab complications become learning rather than repetition.
