Acute lower limb ischaemia secondary to aortic compression from uterine fibroid

Nawawi SH, Wan Ibrahim WZ, Yahya MM, Ramli R

BMJ Case Rep, 2023 Aug 17;16(8).
PMID: 37591622 DOI: 10.1136/bcr-2022-253129

A woman in her early 50s with uncontrolled diabetes mellitus and a huge uterine fibroid presented to the emergency department with diabetic ketoacidosis and bilateral acute lower limb ischaemia. Vascular and advanced imaging studies confirmed distal aortic compression by a huge uterine fibroid, resulting in extensive lower limb arterial thrombosis. After resuscitation, the patient underwent emergency hysterectomy, thromboembolectomy and amputation of the right leg. She remained critically ill and died of fulminant sepsis and multiorgan failure 10 days later. This case reports the effects of external vascular compression by a large pelvic mass.

Fulltext Ischaemic gangrene of leg due to ring constriction: a case report

Thambi Dorai CR

Med J Malaysia, 1986 Jun;41(2):173-5.
PMID: 3547051

An infant with bilateral congenital ring constrictions in the legs presenting with ischaemic gangrene of one leg is reported. The ischaemia was precipitated by greenstick fracture, the constriction ring producing a 'tourniquet effect' on the swollen tissues. Prophylactic release of deep annular constrictions is advised to prevent complications.

Fulltext Successful revascularisation of near total amputation of the upper limb after ten hours of warm ischaemia

Merican AM, Kwan MK, Cheok CY, Wong ELW, Sara TA

Med J Malaysia, 2005 Jun;60(2):218-21.
PMID: 16114164

Near total amputation of the upper limb if unsalvageable would cause severe disability. However, delayed revascularisation can be life threatening. We report two cases of revascularisation of the upper limb following near total amputation that was successful and functional after a warm ischaemic time of ten hours. The first was a traction avulsion injury of the arm leaving major nerves contused but in continuity. The second was a sharp injury through the mid-forearm attached by only a bridge of skin. Attempting revascularisation of a proximal injury beyond 6 hours, in selected cases is worthwhile.

Fulltext Revascularization for foot salvage in diabetic critical foot ischaemia

Yii MK, Liew NC

Med J Malaysia, 1999 Sep;54(3):325-8.
PMID: 11045058

A consecutive series of 32 diabetic patients, 16 male and 16 female, who presented to the authors with critical limb ischaemia was reviewed over a two-year period. Atherosclerotic risk factors and co-morbidities were present in 56% of these patients. Diagnostic angiography was performed in all patients. Revascularization was achieved in 91% of the cases with three perioperative deaths. Ten bypasses were anastomosed distally to one of the crural or ankle arteries at the foot. Major amputations were required in five patients who had had revascularization and in 4 of these gross sepsis was the main factor responsible for limb loss despite patent grafts. The primary graft patency rates at one month and one year were 96% and 90% respectively. Surgical reconstruction was possible in the majority of diabetic patients with critical ischaemia and should be offered to patients preferably before the establishment of gross sepsis to improve limb salvage.

Karanth VK, Karanth TK, Karanth L

Cochrane Database Syst Rev, 2016 12 13;12:CD011519.

BACKGROUND: Critical lower limb ischaemia (CLI) is a manifestation of peripheral arterial disease (PAD) that is seen in patients with typical chronic ischaemic rest pain or patients with ischaemic skin lesions - ulcers or gangrene - for longer than 2 weeks. Critical lower limb ischaemia is the most severe form of PAD, and interventions to improve arterial perfusion become necessary. Although surgical bypass has been the gold standard for revascularisation, the extent or the site of disease may be such that the artery cannot be reconstructed or bypassed. These patients require other modalities of treatment, for example, vasodilatation by drugs or lumbar sympathectomy to relieve pain at rest and to avoid amputations. A systematic review of randomised controlled trials is required to evaluate the effects of lumbar sympathectomy in treating patients with CLI due to non-reconstructable PAD.
OBJECTIVES: The objective of this review is to assess the effects of lumbar sympathectomy by open, laparoscopic and percutaneous methods compared with no treatment or compared with any other method of lumbar sympathectomy in patients with CLI due to non-reconstructable PAD.
SEARCH METHODS: The Cochrane Vascular Information Specialist (CIS) searched the Specialised Register (January 2016) and the Cochrane Central Register of Controlled Trials (CENTRAL; 2015, Issue 12). In addition, the CIS searched clinical trials databases for details of ongoing and unpublished studies.
SELECTION CRITERIA: Randomised controlled trials (RCTs) comparing any of the treatment modalities of lumbar sympathectomy, such as open, laparoscopic and chemical percutaneous methods, with no treatment or with any other method of lumbar sympathectomy for CLI due to non-reconstructable PAD were eligible. To decrease the bias of including participants that may be incorrectly diagnosed with CLI, review authors defined CLI as persistently recurring ischaemic rest pain requiring regular analgesia for more than two weeks, or ulceration or gangrene of the foot or toes, attributable to objectively proven arterial occlusive disease by measurement of ankle pressure of < 50 mmHg or toe pressure < 30 mmHg. We defined non-reconstructable PAD as a resting ankle brachial index (ABI) < 0.9 when no reasonable open surgical or endovascular revascularisation treatment option is available, as determined by individual trial vascular specialists.
DATA COLLECTION AND ANALYSIS: Two review authors independently assessed studies identified for potential inclusion in the review. We planned to conduct data collection and analysis in accordance with the Cochrane Handbook for Systematic Review of Interventions.
MAIN RESULTS: We identified no studies that met the predefined inclusion criteria. To decrease the bias of including participants who may be incorrectly diagnosed with CLI, we based our inclusion criteria on objective tests, as described above. The randomised trials identified by the literature search were performed before such objective criteria for selection were applied and therefore were not eligible for inclusion in the review.
AUTHORS' CONCLUSIONS: We identified no RCTs assessing effects of lumbar sympathectomy by open, laparoscopic and percutaneous methods compared with no treatment or compared with any other method of lumbar sympathectomy in patients with CLI due to non-reconstructable PAD. High-quality studies are needed.

Haematemesis resulting from ischaemic strangulating intestinal obstruction

Moissinac K, Ponnampalam J, Chong Se To B

Eur J Emerg Med, 2000 Dec;7(4):297-9.
PMID: 11764140

Although bleeding into the intestinal lumen may occur in strangulating intestinal obstruction, haematemesis is infrequently encountered. We report on a patient who presented with haematemesis and who had, in addition, clinical and radiological features of small bowel obstruction. Upper gastrointestinal endoscopy did not locate the source of bleeding. At laparotomy, which was performed because of clinical deterioration, gangrenous strangulated small bowel secondary to adhesive obstruction was found. In a patient with non-resolving intestinal obstruction, a deterioration in the condition is a clear indication for exploration. Haematemesis occurring concurrently may be a marker of intestinal strangulation, adds strength to the indication and highlights the urgency of the need for exploration.

Intra-arterial allogeneic mesenchymal stem cells for critical limb ischemia are safe and efficacious: report of a phase I study

Das AK, Bin Abdullah BJ, Dhillon SS, Vijanari A, Anoop CH, Gupta PK

World J Surg, 2013 Apr;37(4):915-22.
PMID: 23307180 DOI: 10.1007/s00268-012-1892-6

BACKGROUND: Critical limb ischemia (CLI) caused by peripheral arterial disease is associated with significant morbidity and mortality. This condition is associated with a 30 % amputation rate as well as mortality levels which might be as high as 25 %. There is no pharmacological therapy available, but several reports have suggested that mesenchymal stem cells (MSCs) may be a useful therapeutic option.
METHODS: This study, done at a university hospital, evaluated 13 patients for a phase I trial to investigate the safety and efficacy of intra-arterial MSCs in CLI patients. Eight patients with ten affected limbs were recruited for the study. As two patients (three limbs) died of ischemic cardiac events during the 6-month follow-up period, seven limbs were finally evaluated for the study.
RESULTS: There was significant pain relief. Visual analog scale (VAS) scores decreased from 2.29 ± 0.29 to 0.5 ± 0.34 (p < 0.05), ankle brachial pressure index (ABPI) increased significantly from 0.56 ± 0.02 to 0.67 ± 0.021 (p < 0.01), and transcutaneous oxygen pressure (TcPO2) also increased significantly in the foot from 13.57 ± 3.63 to 38 ± 3.47. Similar improvement was seen in the leg as well as the thigh. There was 86 % limb salvage and six of seven ulcers showed complete or partial healing.
CONCLUSION: It was concluded that intra-arterial MSCs could be safely administered to patients with CLI and was associated with significant therapeutic benefits.

Fulltext Review of the Long-term Effects of Autologous Bone-Marrow Mononuclear Cell Implantation on Clinical Outcomes in Patients with Critical Limb Ischemia

Yusoff FM, Kajikawa M, Matsui S, Hashimoto H, Kishimoto S, Maruhashi T, et al.

Sci Rep, 2019 05 22;9(1):7711.
PMID: 31118440 DOI: 10.1038/s41598-019-44176-5

Critical limb ischemia (CLI) is associated with a high risk of limb amputation. It has been shown that cell therapy is safe and has beneficial effects on ischemic clinical symptoms in patients with CLI. The aim of this study was to further investigate the outcomes of intramuscular injection of autologous bone-marrow mononuclear cells (BM-MNCs) in a long-term follow-up period in atherosclerotic peripheral arterial disease (PAD) patients who have no optional therapy. This study was a retrospective and observational study that was carried out to evaluate long-term clinical outcomes in 42 lower limbs of 30 patients with atherosclerotic PAD who underwent BM-MNC implantation. The median follow-up period was 9.25 (range, 6-16) years. The overall amputation-free rates were 73.0% at 5 years after BM-MNC implantation and 70.4% at 10 years in patients with atherosclerotic PAD. The overall amputation-free rates at 5 years and at 10 years after implantation of BM-MNCs were significantly higher in atherosclerotic PAD patients than in internal controls and historical controls. There were no significant differences in amputation rates between the internal control group and historical control group. The rate of overall survival was not significantly different between the BM-MNC implantation group and the historical control group. Implantation of autologous BM-MNCs is feasible for a long-term follow-up period in patients with CLI who have no optional therapy.

Fulltext Early and aggressive ISR with a polymer- and carrier-free drug-coated stent system

Loch A, Bewersdorf JP, Veeriah RS

Indian Heart J, 2017 03 17;69(5):651-654.
PMID: 29054192 DOI: 10.1016/j.ihj.2017.03.002

The LEADERS FREE trial concluded that the polymer free drug-coated BioFreedom™ stent appeared to be both safer and more effective than bare-metal stents (BMS) with an ISR rate comparable to traditional DES without the need for prolonged DAPT. We implanted 45 BioFreedom™ stents in 34 patients over a 4-month period. 4 patients represented early (106-238 days after the implant procedure) with angina symptoms and severe ISR was detected in all patients. The rate of severe and early ISR detected in our patient population of 11.8% is comparable to that of traditional BMS. Further studies are warranted.
