Vascular Injuries Caused by Acupuncture
Article Outline
Abstract
Aim
To systematically review the literature on vascular injuries caused by acupuncture.
Method
Systematic literature search in Medline and PubMed.
Results
Twentyone cases were identified and the majority developed symptoms in direct connection with the acupuncture treatment. Three patients died, two from pericardial tamponade and one from an aortoduodenal fistula. There were five more tamponades, seven pseudoaneurysms, two with ischaemia, two with venous thrombosis, one with compartment syndrome and one with bleeding. The two patients with ischaemia had remaining sequeleae. Information on follow-up was suboptimal with no information in nine patients.
Conclusion
Vascular injuries are rare, bleeding and pseudoaneurysm dominating. Follow-up is insufficient in the hitherto published papers.
Keywords: Vascular injury, Acupuncture, Iatrogenic
Introduction
Acupuncture is a very old treatment for various disorders. It has survived and is still frequently used, also in non-eastern countries. Although patient records are not always used as in western medicine it seems reasonable to consider the treatment as very safe. Reported complications are rare but some are serious such as infections (bacterial endocarditis, septicaemia, HIV, hepatitis), pneumothorax, spinal cord lesion and allergic reactions.1
The aim of this systematic review is to analyze injuries of the cardiovascular system induced by acupuncture.
Method
MEDLINE and PubMed were searched without time limitation. Acupuncture was combined with various vascular terms as well as with vessel anatomy. Reference lists in identified papers were scrutinized. Articles in English, German, French and Scandinavian languages were read as were papers with English summary (one Japanese identified: Nakanishi et al. 2007).2
Results
Twentyone cases were identified (21 publications).3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21 There were twelve females, eight males and in one patient the gender was not given. Age was not reported in two patients, in the remaining median age was 61 years (range 25–83). The indications for acupuncture were back pain in seven, abdominal pain in two and shoulder stiffness, fibromyalgia, knee joint arthrosis, rheumatoid arthritis, ulcerative colitis, intermittent claudication and asthma in one each. In five patients the indication was not reported. Nine acupuncture treatments were given by experienced acupuncturists, two patients were treating themselves and in ten there is no information about the education or skill of the acupuncturist. In three cases it is stated that electroacupuncture was used.
Eighteen patients experienced symptoms immediately in relation to the acupuncture treatment, in one patient symptoms started after several hours and in one after one day. In one there is no exact information. In three patients the diagnosis was made at autopsy, in the remaining the diagnostic delay was four days (median; range immediately to 6 months).
In Table 1 the acupuncture site is shown, as well as symptomatology, diagnostic test used and how the patients were treated. As could be expected from a vascular puncture injury the symptoms are due to bleeding, the development of a pseudoaneurysm or vascular occlusion. Thee was no information on underlying vascular pathophysiology. Three patients died before treatment, two from pericardial tamponade and one from an aortoduodenal fistula with massive haematemesis. In the last case the diagnosis was made with CT, the patient dying from haemorrhagic shock while waiting for surgery. When diagnosis was established the remaining patients were treated accordingly. One patient with a popliteal occlusion came to diagnosis after half a year, developing symptom of ischaemia immediately after the puncture but with spontaneous improvement. She was treated without invasive intervention and suffered from mild claudication. One patient with some calf muscle necrosis after compartment syndrome had a small functional defect. In one patient severe ischaemia developed leading to gangrene and amputation. The remaining survivors had an uneventful course. The problem, however, is the poor information on follow-up time: Three patients died and one underwent arm amputation, in nine no time is reported and in the remaining eight it was in median 4 months (one week–3 years).

aThis case caused debate whether the gangrene due to thrombotic occlusion of the brachial artery was caused by the acupuncture or by the underlying disease (ulcerative colitis) with increased thrombogenicity.10 One needle was used. For delay in handling probably caused the unfortunate outcome. |
Discussion
With the background that acupuncture has been used for thousands of years in Asian countries and since a few decades also in the western part of the world – in fact increasingly so – the frequency of severe complications is extremely low.22, 23, 24 In a postal questionnaire covering 34 407 acupuncture treatments there were two cases of “heavy bruising” indicating vessel puncture.24 None required hospital admission, though. Serious adverse events have been estimated to 0.55 per 10 000 patients undergoing acupuncture treatment.25 This is well within the 95% confidence interval between 0–1.1 per 10 000 treatments suggested by MacPherson et al.,24 the incidence being calculated from 12 prospective studies including 109 152 patients undergoing 1107 270 treatments. This obviously means that vascular injuries are, indeed, rare. At the same time we have to realize that serious complications may be hidden in areas where reporting is suboptimal and where there is no regulation of acupuncturist practice. A limiatation of the study is that journals in Asian languages without English summary has not been possible to evaluate. None the less it is important to be aware of the existence of also rare major side effects and thus the possibility to meet such patients.
By scrutinizing the literature – the interest being stimulated by an own patient3 – only twentyone patients were identified. The most dramatic consequence is presternal puncture with cardiac tamponade, which may be fatal if not correctly diagnosed and promptly treated. Otherwise the dominating injury was development of a pseudoaneurysm. As the hole in the artery caused by an acupuncture needle must be very small the treatment of choice today would seem to be ultrasound guided thrombin injection.26 From a vascular surgical point of view the acupuncture induced injuries are not special and should be treated as other puncture induced injuries. The important message is to have knowledge of the possibility and as acupuncture is increasingly used, this information must be part of the medical history in unclear cases of vascular occlusion or pseudoaneurysm. Detailed anatomical knowledge by the acupuncturists obviously is a fundamental requirement for prevention. They should also be aware of potential serious complications that may occur. Acupuncture needles may be as long as 125
mm, which explains the possibility of also rather deep injuries.
There has been a decrease in reported acupuncture complications between 1965 and 1999 with a peak incidence 1976 to 198523 and there are no recent indicence reports. This does not, however, necessarily mean a decrease in the true incidence as registration and reporting routines probably are far from optimal. As indicated in the results section of this paper this is valid also for case reports. There is an ongoing discussion on the value of case reports and some journals do not even publish them. Our view is that such an editorial restriction is basically correct, but some case reports are definitely of value increasing our knowledge on rare diseases and complications and new treatment options. Journals accepting case reports should, however, have criteria on which information is necessary for considering publication. When it comes to vascular injury the competence of the acupuncturist seems important as well as a long term enough follow up. A year or more seem reasonable in cases with vascular injuries. The optimal design of a trial dealing with acupuncture induced complications, however, would be having a prospective acupuncture registry with high attendance rate, high compliance and a sufficient number of patients.
