Intraoperative hypertensive crisis Archives

Tag: Intraoperative hypertensive crisis

In the simplest of terms and in the context of Neuroendocrine Tumours, it is a dangerous change in blood pressure, heart rate, and breathing (technical term – cardiopulmonary hemodynamic instability). On an operating table under anaesthetics or an invasive procedure such as liver embolization, this can actually be life threatening. Incidentally, this happens with many other types of conditions (hormones and peptides do exist in other illnesses). However, with a patient already oversecreting these hormones and peptides, it could be a life or death situation.

With catecholamine secreting NETs known as Pheochromocytoma and Paraganglioma where there might need to be significant pre-operative preparation in addition to peri-operative measures and post surgical treatment and monitoring, to prevent ‘Intraoperative Hypertensive Crisis

The 5 E’s (of Carcinoid Syndrome)

By Ronny Allan Aug 27, 2024 5 Comments

The 5 Es was a good idea but the boundary was never properly defined. I don't believe it applies to all NETs and I don't believe it is confined to carcinoid syndrome Original Post Since my diagnosis, I seem to have been in a perpetual learning phase! What not to do, what not to eat, what not to read! However, early on in my experience, I came across a list of 'E' words (5 of them) which is a handy reminder for Carcinoid Syndrome patients, particularly those whose symptoms are not under control. When I say "carcinoid syndrome" in this article,…

Neuroendocrine Cancer – Horrible Hormones

By Ronny Allan Mar 22, 2024 15 Comments

Updated and reviewed 20th March 2024 Hormonal imbalances are quite common in many conditions including day to day stuff. With Neuroendocrine Cancer, it can be a real challenge both at diagnostic and maintenance phases. In addition to the cancer angle, there's some strange stuff going on, inexplicable, frightening for the patient, an unwanted ingredient causing chaos!Until I was diagnosed with metastatic Neuroendocrine Cancer, I didn't have a clue about hormones - it's one of those things you just take for granted. However, hormones are vital to human health (male and female) and it's only when things go wrong you suddenly…

Neuroendocrine Tumours: a spotlight on Pheochromocytoma and Paraganglioma

By Ronny Allan Dec 14, 2016 4 Comments

Updated 19th August 2025I spend a lot of time talking about the most common forms of Neuroendocrine Tumours (NETs), but what about the less well-known types? As part of my commitment to all types of NETs, I'd like to shine a light on two less common tumour types known as Pheochromocytomas and Paragangliomas - with an incidence rate of approximately 8 per million per year. They are normally grouped together, and the definitions below will confirm why. If you think it's difficult to diagnose a mainstream NET, this particular sub-type is a real challenge.So, let's get definitions out of the…
