Clinical Information

Patient initials or Identifier Number

Relevant Clinical History and Physical Exam

Since January 2023, the patient began to experience anginal pain, radiating to the left arm during physical activity, which resolved after taking nitroglycerin. Due to the progressive deterioration of health and the ineffectiveness of the therapy prescribed at the outpatient stage, the patient was referred for coronary angiography.


Relevant Test Results Prior to Catheterization

Clinical bloodtest: RBC – 4,4 10in 12 tbsp. / l; HGB - 135 g / l;  MCV – 91,3 cubic meters; PLT - 260 10 in 9 st. / l;MPV – 8.7 cubic meters; Leukocytes – 6.7 10 in 9 tbsp. / l; Segmentedneutrophils,% - 73.9%; Lymphocytes – 15,9%; Monocytes - 8.5%; Eosinophils - 0.8%;Basophils - 0.8%; Erythrocyte sedimentation rate - 28 mm / h;Biochemicalblood test: Potassium – 4,13  mmol / l;Glucose – 5,7  mmol / L; GFR (MDRD) M – 62,9ml / min / 1.73m2; Serum creatinine – 81,8¥ìmol / l.

Relevant Catheterization Findings

Type of coronary blood supply: left.LM: has uneven contours.LAD: has uneven contours along its entire length.Cx: 70% stenotic at the mouth, 99% stenotic in the distal segment.RCA: diffusely changed, 90% stenotic in the proximal segment.




Interventional Management

Procedural Step

A guiding catheter was placed in the ostium of the LM. A guidewire was inserted through the stenosed area into the distal Cx bed. The second guidewire was inserted into the distal LAD bed. A 3.0*28 mm DES was implanted into the distal segment of the Cx. A 3.5*34 mm DES was implanted into the Cx with transition to the LM. POT was performed using a 5.0x10mm balloon catheter. During dilatation of the balloon catheter, the balloon catheter became jammed. Numerous attempts to deflate the balloon catheter were unsuccessful. The guide catheter with balloon catheter and guidewires were removed as a complex. The guiding catheter was re-installed in the ostium of the LM. The guidewire was passed into the distal Cx bed. The second guidewire was re-passed through the stent cell into the distal segment of the LAD. 3.5x15 mm and 3.5x15 mm balloon catheters were used to postdilate the stented sections of the LM, LAD, and Cx by "kissing balloons" method. The DES 3.5*38 mm was implanted into the proximal segment of the LAD with transition to the LM. POT was performed using a 5.0x10mm balloon catheter. The guidewire was re-passed through the stent cell into the distal segment of the Cx. 3.5x15 mm and 3.5x15 mm balloon catheters were used to postdilate the stented sections of the LM, LAD, and Cx by "kissing balloons" method.  POT  was performed using a 5.0x10mm balloon catheter. The control angiography showed the blood flow along the TIMI III arteries. The operation was completed.


Case Summary

Balloon catheter jamming during coronary stenting is quite rare, but it is necessary to know the treatment options for this complication. Knowledge of methods for treating complications helps the operator select the most appropriate treatment method and achieve optimal stenting results.
